EXECUTIVE SUMMARY

The Advanced Training Institute on Climatic Variabilityand Food Security was designed to equip youngagriculture and food security professionals in developingcountries to apply advances in climate prediction at aseasonal lead time to their home institutions’ ongoingefforts to address climate-sensitive aspects of agriculturalproduction, food insecurity and rural poverty. TheInstitute comprises three components: intensive training,follow-up research, and a final workshop. TheInternational Research Institute (IRI) for ClimatePrediction designed, implemented and hosted the initialphase of the Training Institute, in coordination with theGlobal Change System for Analysis, Research and Training(START), and with generous financial support from theDavid and Lucile Packard Foundation.

Participant Selection

Nineteen outstanding early- to mid-career agriculture andfood security professionals from fourteen countries inAsia, Africa and Latin America participated. The selectionprocess was highly competitive. Seventy-seven peopleapplied for only twenty positions. Participants wereevaluated by the Director, other IRI scientists, and theInternational Advisory Committee based on a well-definedset of criteria that included:

• Academic foundation,

• Grasp of the central issues, expressed in a Statement ofInterest,

• Vision and strategy for applying concepts within asignificant follow-up project,

• Home institution’s relevance, capacity and connectionto target stakeholders,

• The applicant’s influence within their institution, and

• Potential for long-term impact.

Intensive Training Phase

The intensive training component of the Training Institutewas held at the IRI facility in Palisades, New York, 8-26July 2002. The workshop curriculum provided a balanceof relevant concepts and methods from the physical,biological, social and integrative systems sciences.Twenty-two faculty members led the participants throughthe following topics:

• Understanding and predicting climate fluctuations.

• Understanding and predicting agricultural impacts.

• Understanding decision makers.

• Analyzing management responses to forecasts.

• Communicating forecast information.

• Institutionalizing support for forecast applications.

• How all the pieces fit together in the design ofpractical, problem-focused projects.

• Developing proposals to obtain project resources.

The curriculum was heavily oriented toward methodology.Hands-on exercises in the afternoons reenforced conceptspresented in morning lectures. The trainees showedconsistent enthusiasm and a high degree of competencethroughout the workshop.

Project Implementation Phase

A unique element of this Training Institute is seed grantsfor follow-up project work. The competitive seed grantprogram clearly motivated participants. It provides amechanism to ensure immediate follow up and to embedthe concepts and approaches within the long-termprograms of the participants’ home institutions. Trainingin proposal development, feedback from peers andorganizers before and during the workshop, individualproposal clinics, and methods learned during the workshopimproved project design and presentation. Everyparticipant left with a funded project, and has beenassigned a senior scientist to serve as a mentor. Projectmentors (a) serve as a resource persons, (b) provideaccountability to ensure that the project stays on track,including approving mid-term and final reports, (c) helpexpand the participant’s network of contacts and (d) areavailable to serve as advocates with participant’s homeinstitutions. Home institutions have committed to supportthe projects with in-kind contributions. The immediateresult is 19 ongoing, funded, participant-led projects in 14countries, that focus on various aspects of climate andfood security.

Synthesis Phase

After completing projects, the participants will reconveneat a summary workshop to present their results, share theirexperiences, synthesize lessons learned, and prepare aresulting publication. The final workshop will tentativelycoincide with the Fourth International Crop Science

Congress in Brisbane, Australia, in September 2004.

Advisory Committee

An International Advisory Committee of ten distinguishedscientists provided oversight. Their contributions includedevaluating applicants and selecting trainees, providinginput to the curriculum, evaluating follow-up projects andguiding grant award decisions and, in several cases,serving as project mentors.

A Suite of Intensive Training Institutes

The Advanced Training Institute on Climatic Variabilityand Food Security is the first of three Intensive TrainingInstitutes in Global Change Science, sponsored by STARTand the David and Lucile Packard Foundation. The othersare:

• Urbanization, Emissions and the Global Carbon Cycle(4-22 August 2003, National Center for AtmosphericResearch, Boulder, Colorado, USA)

• Assessing Vulnerability to Global Change and Global

Environmental Risks

All aim at enhancing the pool of trained young scientistsfrom developing countries who are able to play aleadership role in cross-disciplinary approaches to keyissues of global environmental change and sustainabledevelopment. All three incorporate funds for follow-upresearch grants and a summary workshop. The sponsorsbelieve that the momentum and critical mass mobilized inthe training institute coupled with follow-up research anda synthesis workshop will yield greater synergies thantraining alone, and lead to sustained collaborative researchnetworks.

A Framework for Developing AgriculturalApplications of Seasonal Forecasts

James Hansen

Advances in our ability to predict climate fluctuationsmonths in advance suggest opportunity to improvemanagement of climatic risk in agriculture, but only ifparticular conditions are in place. I will relate thecomponents of the Training Institute to a set ofprerequisites to beneficial use of seasonal climateforecasts. The first prerequisite is that forecastinformation must address a need that is both real andperceived. Second, benefit arises only through viabledecision options that are sensitive to forecast information.Third, benefit depends on prediction of the components ofclimate variability that are relevant to viable decisions.Fourth, appropriate forecast use requires effectivecommunication of relevant information. Finally,sustained use requires institutional commitment andfavorable policies. Considering three phases of effort isuseful: an exploratory phase to gain understanding andassess potential, a pilot phase characterized by co-learningbetween researchers and target decision makers, and anoperational phase focusing on engaging and equippingrelevant institutions.

Keynote Address:Beyond Climate Information:

What Else Is Needed for Food Security and Poverty Alleviation?

Jacob Kijne

This presentation discusses the conditions under whichfood security needs to be achieved, includingtechnological changes, degradation of natural resources,competition for scarce water, the changing structure offarming, and international agricultural trade and itssubsidies. It analyses the link between food security andrural poverty, and presents food production trends indeveloping countries. The role of irrigation in foodproduction is discussed. Important institutional aspects,such as the need for farmers’ involvement in theimprovement of food production, will be illustrated byseveral case studies. The presentation ends by specifyingthe most promising options and opportunities forimproving food production in developing countries andthe role of climate information in this process.

Afternoon Workshop:Funding Your Own Research:

How to Write a Winning Proposal

Marian Fuchs-Carsch

The primary purpose of proposal writing is to persuade,not to inform. Principles of persuasive writing apply.First, think about your reader. Second, spoon feed yourreader. Make your writing easy to read by using simple,direct sentences; bullets; active voice; and positivelanguage. Third, plan before you write. Writing topersuade requires appealing to the self-interest of thereader (i.e., the donor), and writing with passion.Development donors generally fall within a fewcategories, but represent a range of goals and constraints.Although development goals are priority, development

donors may fund projects with a research component.Rules differ, depending on whether a proposal is sole-source or a response to a request for proposals.Partnerships are always an asset. A project is acombination of inputs managed in a certain way, toachieve desired outputs, and ultimately desired impacts.The essential elements of a project are goals andobjectives, inputs, a management plan, activities, outputsand a budget. Objectives should be specific, measurable,achievable, realistic and time-bound. A concept note isuseful for gaining internal approval, enlisting partners, andgaining preliminary donor approval. A full proposal ismore involved, should follow any donor guidelines, andshould be subjected to a policy of in-house review. Thepresentation presents generic templates and extensiveguidance for writing concept notes and proposals.

Module 1: Understanding and Predicting Climate Fluctuations

LECTURE SUMMARIES

The Scientific Basis for Seasonal Prediction

Neil Ward

Although the chaotic nature of the atmosphere precludesprediction of weather events beyond about 10-14 days,climate fluctuations can be anticipated months ahead dueto the influence of solar irradiance, land vegetation, sea iceand sea surface temperatures (SSTs) on the atmosphere.SST patterns influence climate patterns around the globe.Their persistence brings a degree of predictability. Asimplified model highlights one effect of SSTs on thetropical atmosphere. The bottom 3 km “boundary layer”over the tropical oceans is well mixed. Its temperaturereflects that of the ocean surface. The difference in weightbetween warm and cold air creates pressure gradients thatinduce winds that converge and rise over warm water. Asthe warm air rises, it cools, causing its moisture toprecipitate as rain. A 10-km effective lid causes rising airto spread and descend elsewhere, creating three-dimensional circulation patterns. Descending air inhibitsclouds and rain. Friction and the Coriolis force modifythe resulting circulation. Latent heating associated withlarge-scale ascent triggers atmospheric waves that travelinto mid-latitudes. Away from the tropics, the Coriolisforce has a greater influence than SSTs.

Ocean-Atmosphere Interactions and El Niño

Lisa Goddard

Coupled ocean-atmosphere interaction occurs in all thetropical ocean basins. However, the Pacific Ocean exertsa unique influence on the global climate system. Its largesize allows for: (a) relatively long time scales, leading topotential predictability of El Niño and La Niña; (b) largeamplitude growth of coupled anomalies; (c) potential forsustained oscillations; and (d) large spatial shifts inconvection and thus atmospheric heating, impacting globalcirculation. Longitudinal shifts in SST patterns associatedwith El Niño or La Niña induce anomalous low-levelwinds, leading to anomalous convergence and rainfall,resulting in anomalous upper-level winds, which finallyinfluences anomalous subsidence. Convergence andsubsidence feed back to low-level winds which, in turn,influence SST patterns. Atmospheric circulation changesinduced by El Niño or La Niña often modify SST in othertropical ocean basins. SST anomalies in the Indian andtropical Atlantic Oceans can play a significant role inaffecting climate variability of neighboring regions thatmay be modified by the atmospheric response to SSTanomalies in the tropical Pacific.

Evaluating Predictability:Dynamic Climate Models

Neil Ward

General Circulation Models (GCMs) represent theatmosphere throughout a 3-dimensional grid, and simulateweather every few minutes through a season. The modelsrequire initial atmospheric conditions, and continuous SSTboundary conditions. Equations represent all keydeterminants of the atmosphere’s evolution. The modelatmosphere responds to incoming solar radiation at itsupper boundary and SSTs at its lower boundary.Equations specify how heat and moisture enter the lowestlayer and permeate through the atmosphere. There isalways a battle between the influence of SSTs and internalatmospheric process that limit predictability from SSTforcing. To address this, we run the model multiple timeswith different initial atmospheric conditions. Thedistribution among model runs indicates the model’s rangeof possible climatic conditions. The average among runscan be considered the model’s best forecast. Becausesome GCMs perform better than others in particularregions, conclusions about lack of prediction skill shouldnot be based on results of a single model. Evidence ofpredictability should be based on both GCM results andevidence of a plausible physical mechanism.

Methods of Prediction

Neil Ward

We consider five methods. First, coupled GCMs, includeocean process and their dynamic interaction with theatmosphere – the theoretically most appealing approach.They can predict ENSO-related SST evolution with goodskill and lead time. Second, operational forecast centerstypically use atmospheric GCMs forced with forecastSSTs, derived from coupled GCMs (Pacific) or statisticalmodels (Atlantic and Indian). Third, regional climatemodels (RCMs) simulate the atmosphere at a high (up to20 km) resolution over a limited region to resolve small-scale climatic influences, using GCM-derived boundaryconditions. Fourth, dynamic forecasts may be improvedthrough statistical transformations of model output,including, (a) correction of systematic error, (b) correctionof ensemble spread, (c) optimal model combination, and(d) downscaling. Fifth, statistical prediction methodssometimes perform well, but risk over-fitting and artificialskill unless predictor selection is based on physicalmechanism. Statistical downscaling estimates local-scaleresponses to large-scale model predictions, and can beextended to prediction of, e.g., hydrological, agriculturalor epidemiological impacts of the local climate. Wediscuss statistical and dynamic downscaling in detail.

Climate Data, Climate Monitoringand the Global ENSO Signal

Chet Ropelewski

There has been a revolutionary change in climate scienceover the past 2-3 decades due, in part, to the ability tostore and analyze large amounts of data using moderncomputers. Previously the emphasis was on the massivejob of getting observation data into computer-compatibleform. Much of that work has been completed and anumber of data libraries exist. We are now accustomed toaccessing and analyzing any number of data sets that havebeen prepared with climate analysis as their expresspurpose. However, almost all of the historical data usedin climate research were not gathered with climate studiesin mind. It is only over the past few years that programssuch as the Global Climate Observing System have beendesigned with climate monitoring as a primary focus. Thelack of a climate focus in most of the historical data setslimits our ability to describe, monitor and analyze theclimate. This presentation will discuss seasonal climatevariability from the viewpoint of the availableobservational data and the products derived from thesedata. The presentation will illustrate the capabilities andshortcomings of current climate data to define andmonitor the global ENSO signal.

An introduction to some of the most commonly usedstatistical models in seasonal climate forecasting ispresented. Deterministic-discrete models should belimited to exploration, when sample sizes are small.Contingency tables can transform a deterministic-discreteto a probabilistic model. The probabilistic-discrete modelcan be extended to multiple predictors throughdiscriminant analysis. Deterministic, continuous forecastsuse, e.g., regression. Prediction intervals allowtransformation to a probabilistic forecast. Canonicalmethods are useful with multiple predictors and/orpredictands. The similarities, differences, strengths andweaknesses of each of the models are discussed. We alsoprovide guidelines on how to interpret and compareforecasts from the different models. One of the commonpitfalls in statistical forecasting is the multiplicity problemand resulting “artificial skill.” Cross-validation andretrospective forecasting can help correct artificial skill.

Statistical Transformation of Dynamic Model Output

Henrik Feddersen

Because substantial forecast uncertainty is due to modelerror, statistical postprocessing can often increaseprediction skill. The challenge is to find large-scalefeatures that GCMs simulate well and that correlate withgrid-cell observations. An ideal “index” is one thatmaximizes the explained variance. Principal componentsanalysis (PCA) applies successive linear transformationsthat maximize the remaining explained variance, such thatthe resulting eigenvectors (EOFs) are orthogonal. Thefirst PC of the observed field is an optimal “index,” and isestimated by the first PC of the GCM field. If the PCs ofthe model and observations correlate well in time, we canuse the model PCs as predictors. Singular valuedecomposition (SVD), finds patterns that maximize thefraction of explained covariance in time between the twofields. Canonical correlation analysis (CCA) findspatterns that maximize the correlation between time series.Regardless of the transformation method, the transformedpredictors and predictand are related by a regression modelthat is then used for prediction. A further transformationcorrects negative bias in the spread of ensemble membersfor probabilistic forecasting.

Operational Forecast Systems:The Example of the IRI’s System

Tony Barnston

Each month, the IRI forecasts global temperature andprecipitation for four overlapping 3-month periods. Theprocess uses predicted global SST anomalies, based on acombination of dynamic and statistical models, as input tofour atmospheric general circulation models (AGCMs).For the shortest lead time, the AGCMs are also run withrecent observed SST anomalies. To represent forecastuncertainty, the IRI expresses them in terms of probabilityof falling within low, middle and upper terciles, based inpart on the distribution of multiple runs of each AGCM.Predictions from the four AGCMs are combined into asingle forecast using two multi-model ensemblingtechniques that calculate optimal weights for each AGCM.IRI forecasts incorporate empirical adjustments, includingan ENSO-based probabilistic composite for the locationand season. Ongoing improvements of the IRI forecastsystem include improved SST prediction in the Indian andAtlantic Oceans. Future advances depend on improvedocean observation and increased computational resources.

Evaluating Forecast Quality

Simon Mason

We discuss methods of evaluating the quality of forecasts.Appropriate methods of forecast verification depend onthe type of forecast, i.e., whether discrete or continuous,and whether deterministic or probabilistic. A probabilisticforecast is never “wrong.” In the deterministic-discretecase, we consider rates of hits and misses. Skill comparesthe accuracy of one set of forecasts to that of another (e.g.,climatology, persistence, perpetual forecasts, randomforecasts). In the deterministic-continuous case, we use ameasure of association, e.g., correlation (which does notaccount for bias) or mean squared error. Forprobabilistic-discrete forecasts, the Brier score isanalogous to mean-squared error. Although aprobabilistic forecast can never be wrong, a forecaster’slevel of confidence can be. Reliability deals withcorrectness of probabilities. Sharpness, a function ofaccuracy, deals with the degree to which a forecast reducesuncertainty. Even for deterministic forecasts, there is nosingle measure of the various aspects of forecast quality:accuracy, skill, uncertainty.

Downscaling in Space

Henrik Feddersen

The linear transformation of the GCM output discussedpreviously is based on downscaling large-scale patterns ofvariability to a single grid cell. The transformation isconsidered a correction if the predictand is at the sameresolution as the predictor(s), and downscaling if thepredictand is at a finer (e.g., individual station) spatialresolution. The predictor and predictand need notrepresent the same field. For example, GCM mean sealevel pressure or 850 hPa wind fields might gives accuratedownscaling of rainfall than GCM rainfall. The modeloutput statistics (MOS) approach requires a long trainingperiod in which both GCM output and observations areavailable. Otherwise, a statistical relationship between thepredictand (e.g., station rainfall) and observations of adifferent field (e.g., mean sea level pressure or 850 hPawind) can be used to transform GCM output to estimatethe predictand. This approach is known as perfectprognosis. Whenever it is possible, the MOS approach ispreferred, as it removes systematic model bias, while theperfect prognosis approach does not. Statisticaldownscaling can be applied to statistical properties ofwithin-season variability, e.g., the number of rainy days.

Dynamic Downscaling

Andrew Robertson

We present preliminary results and lessons from a dynamicdownscaling experiment carried out experimentally forNortheast Brazil. The project is a collaboration betweenthe IRI and FUNCEME. The approach is to nest theRegional Spectral Model (RSM) at an 80 km grid overGCM (ECHAM 4.5) output, then nest the RSM at 20 kmwithin the 80 km RSM. We now have a 20 memberensemble run for 30 years. Hindcast skill of mean rainfallis high in the March–May season and in the single monthof April, with anomaly correlations exceeding 0.7 in someareas. We are just starting to evaluate daily statistics. Thesimulated daily rainfall distribution is better from theRSM at 80 km than from the GCM or the RSM at higherresolution. The approach is promising, but is tedious andrelatively expensive. Future research will comparedynamic downscaling skill against statistical downscaling.

Downscaling in Time

Andrew Robertson

Forecast seasonal averages are not always useful toapplications such as agriculture and water resourcemanagement. This lecture discusses the characteristics ofthe weather within a season that are important forapplications. We then consider how these attributes can bequantified in a probabilistic way, and prospects forpredicting them up to several seasons in advance. Astochastic approach is key, since weather cannot bepredicted deterministically more than about two weeks inadvance. We would like to be able to predict daily weatherscenarios that can be used as inputs to, e.g., cropsimulation models. The stochastic weather generator is awell-established technique for generating daily sequencesof precipitation, daily maximum and minimumtemperatures and solar radiation. We show how theparameters for these models can be estimated fromobserved data and predicted from climate-modelseasonal-mean predictions. The lecture compares thisapproach to using historical analogues, and to direct useof (statistically corrected) daily climate-model output.

Weather-Sensitive Agricultural Models:Principles

Jim Jones

The variability of the environment in space and time, andthe complexity of crop responses to climate, soil andmanagement, call for an integrative systems approach.Crop models addresses the limitations of traditional fieldexperiments, integrate knowledge across disciplines, andbridge the gap between information created by disciplinaryresearch and needed for decision making. Forrestordiagrams are useful for representing conceptual models.Crop simulation models are based on understanding ofinteractions between plants, soil, weather, andmanagement; predict growth, yield and timing; requireinformation; and can be used for “what-if” experiments.They model mass and energy balances, and integrate theeffects of weather (processes temperature, CO2, day length,solar radiation, sometimes humidity and wind) on growth,

development and the dynamics of water availability.Experiments in Florida and Georgia demonstrate that themodels capture soybean response to weather. Ongoingwork is gradually addressing limitations including: factorsmissing from models, the challenge of spatial variability,input requirements, and model complexity, stability anddocumentation.

to, projected changes in temperatures, precipitation andCO2; and (e) addressing tradeoffs between economic andenvironmental goals for land use decisions. Withinseasonal forecast applications, crop models have been usedto identify optimal field scale management and farm-scalecrop mix, and estimate forecast value. Credibility ofapplications hinges on model evaluation, and sometimesrequires model adaptation. DSSAT is a research tool,developed by international network of researchers, forcrop production analyses. It incorporates: (a)crop-soil-weather models of 16 crops that account formost of the global food crop production, (b) analysis tools(uncertainty, economics), (c) support software (graphics,data management), and (d) GIS linkages for spatialvariability analysis. DSSAT is used in most countries ofthe world for research, teaching and technology transfer.

Predicting Regional Production:Principles

James Hansen

When applying crop simulation models to heterogeneousregions, aggregation error can seriously bias predictions.I will discuss the nature and sources of aggregation errorby comparing with “perfect aggregation.” Aggregationerror includes both mean bias due to nonlinear modelresponse to averaged inputs, and bias of year-to-yearvariability due to imperfect correlation between yieldsfrom different spatial units. The key approaches forimproving spatially aggregated crop yield simulation aresampling model inputs in either geographic or probabilityspace, and calibrating either model inputs or outputs.Calibration depends critically on availability of qualitytime series data at the target spatial scale. I discuss issuesand approaches for dealing with heterogeneity of soil,meteorological and management inputs when predictingspatially-aggregated production.

Predicting Regional Production:Applications

Jim Jones

I present three case studies that illustrate how models canbe used to predict regional-scale yield response to climatevariations. A study of soybean yield variations in a singlecounty in Georgia shows that variations in yield associatedwith climate variations over time can be estimated withaccuracies on the order of 5-10%. Use of simulateddeviations and historical yields to predict yield variationsis a good first approximation (errors on the order of10-20%). Availability of historical yields can improvepredictions, reducing errors by half or more. From a studyof soybean yields throughout Georgia, I introduce the yieldgap concept and reasons for yield bias. RMSE averaged14% when predicting yields for independent years after

correcting for bias. Bias varied considerably across thestate, implying variations in management and other factorsnot accounted for in the model. Other approaches mayfurther reduce bias. Finally, a millet yield forecastingsystem for early warning application in Burkina Fasoillustrates the role of GIS, the use of satellite-derivedrainfall coupled with generated temperature and solarradiation values, and sequential updating of forecasts andtheir uncertainty through the growing season. Yieldsforecast at mid season were within 15% of final yields.Although more work is needed, this approach showsconsiderable promise.

Linking Climate Predictionto Agricultural Models

James Hansen

The spatio-temporal scale mismatch between dynamicclimate models and agricultural (e.g., crop) simulationmodels is an ongoing challenge for model applications.The set of plausible information pathways suggests severalpotential methods for linking climate prediction toagricultural simulation models. First, classification (e.g.,ENSO phases) and selection of historic analogs has longbeen the standard method. The second approach, direct useof dynamic climate model output, is unlikely to give goodresults due to distortion of day-to-day variability, unlesssophisticated statistical transformations are applied to thedaily climate model output. The third approach, stochastictemporal disaggregation, involves use of a stochasticweather generator to disaggregate seasonal or sub-seasonalpredictions into daily time series with appropriatestatistical properties. The fourth approach, directstatistical prediction, relates the simulated outputs ratherthan the meteorological inputs of a crop model to climaticpredictors. The final approach I discuss is to derive yieldpredictions from probability-weighted historic analogs,e.g., tercile forecasts or a k-nearest-neighbor approach(topic of the next lecture).

Applications of the k-Nearest NeighborMethod for Regression and Resampling

Upmanu Lall

The objectives of this lecture are to (a) provide astructured approach to exploring a regression data set, and(b) introduce and demonstrate the k-nearest neighbor (knn)method. As a weighted average, the knn method is a formof regression. The steps of data exploration are (a)examine any systematic trends, (b) understand the structureof inter-variable relationships, (c) and examine probabilitystructure. Brush and spin plots aid visualization ofrelationships in multivariate data sets. If relationships arelinear and distributions normal (without or with a

17

transformation), then a linear model should be used.Otherwise, use the knn method with distance weights.Applying the knn method requires decisions aboutweighting method (i.e., the kernel function) and number ofneighbors (k). We discuss weighting based on rankdistance to the predictand vector, and criteria for choosingk.

Interpreting Historical Agricultural Data

James Hansen

Historical production records are useful for characterizingand understanding the impacts of predictable componentsof climate variability. Valid purposes of statisticalanalysis include exploration, hypothesis testing, andstatistical prediction. Because non-climatic factors

influence production, statistical analysis of time seriesdata must first account for trends. Choice of statisticaltechniques depend in part on whether the variables aretreated as continuous or discrete, the number of each typeof variable, and the distributions and behavior of each timeseries. I also discuss presentation method. Themultiplicity problem arises when a pair-wise statisticalhypothesis test is applied repeatedly to a data set. Acommon cause is “fishing” for predictability by evaluatinga number of potential predictors or evaluatingrelationships at multiple lead times. The problem alsoarises when considering multiple commodities orlocations simultaneously. Potential solutions includelimiting the variables considered, use of statisticalmethods that control experiment-wise significance, pre-filtering with principle component analysis, andBonferroni correction.

Predict Crop Yields from Seasonal Climate Forecasts

James Hansen

Objective: Become familiar with several promisingapproaches for linking coarse spatial and temporalresolution climate forecasts with crop simulation for topredict yield response to predicted climate fluctuations.

Overview: You will collectively implement and evaluatefive potential methods for producing crop yield forecastsfrom seasonal climate forecasts. Due to the number ofmethods we will consider, this exercise will be conductedin teams. Each of four teams will apply one method togenerate a time series (1970-1996) of maize yieldhindcasts based on seasonal climate hindcasts. Every teamwill also simulate yields with observed weather, calculateseveral measures of goodness of fit between hindcastyields and yields simulated with observed weather, andplot results. Each team will give a short (5 minutes)presentation of results on Wednesday morning. Theexercise will use the same Katumani, Kenya, data used inExercise 2.1. Teams 2-4 will use October-Decemberprecipitation hindcasts derived from ECHAM 3.6, eitherdirectly or as boundary conditions for a high-resolutionnested regional climate model (RSM). Because ECHAMwas run with observed SSTs, the results are not truehindcasts, and probably overestimate true prediction skill.

Four teams will evaluate five methods:

• Team 1: Selection of historic analogs by ENSO phase.

Module 3: Analyzing Management Responses to Forecasts

LECTURE SUMMARIES

A Risk Management Framework

James Hansen

Risk management entails balance between the level and thesecurity of livelihood. Decision trees are a useful way tothink about risky decisions, particularly the sequence ofdecisions, chance and outcomes. A decision tree exampleillustrates risk aversion and the concept of a certaintyequivalent. Expected utility provides a mathematicalfoundation for risk management that can handle a widerrange of scenarios, including those where decision optionsand states of nature are continuous. The shape of a utilityfunction embodies one’s attitudes toward risk. I discussabsolute and relative risk aversion. Although risk aversionis difficult to measure, experience suggests some commonranges of relative risk aversion. The assumptions behindexpected utility theory often do not hold underexperimental conditions. Nevertheless, the frameworkmakes the tradeoff between profit maximization and riskavoidance tractable, and remains useful when itslimitations are understood. Importantly, it provides anobjective basis for recommending incremental responsesthat are consistent with forecast uncertainty and risktolerance.

Principles of Retrospective Decision Analysis

James Hansen

Ex-ante, retrospective decision analysis is useful foranswering several relevant questions. Retrospectiveanalysis accounts for the probabilistic nature of forecastsby considering what optimal decisions and outcomeswould have been over a past series of years. Economistsdefine information value as the difference in expectedoutcomes between optimal use of the new information andoptimal use of the prior information. It is useful todistinguish between “objective” value based on expectedoutcomes, and “subjective” value based on certaintyequivalents. In spite of limitations, the forecast valueframework provides a useful metric for, e.g., identifyingwhich decisions are most sensitive to forecasts, comparingdifferent forecast systems, or evaluating tradeoffs betweenforecast lead time and skill. Optimal strategies identifiedfrom such an analysis can be an entry point for discussionwith decision makers or a starting point for traditionalresearch. The general framework is meaningful only in thecontext of a well-defined system.

Constrained Optimization Models for Decision Analysis

David Letson

Ex-ante evaluation of climate forecast use requires thatwe model a range of decisions. Constrained optimizationis a useful framework for structuring decisions thatinvolve risk aversion, intermediate products, distributionnetworks, inventory management, and multiple objectives.The general steps to finding an analytical solution to aconstrained optimization problem are: (a) form aLagrangean, (b) differentiate with respect to all decisionvariables, and (c) form and interpret complementaryslackness conditions. Examples illustrate howmanagement of intermediate product processing in anindustry value chain, sequential inventory storagedecisions, and decisions with multiple objectives can beformulated and solved as constrained optimizationproblems.

Enterprise-Level Decision Analysis

James Hansen

The enterprise is the lowest level in the agriculturalsystems hierarchy that is managed. Production enterprisesare typically analyzed on a unit land area basis. Scaleindependence simplifies analyses and generalization ofresults, but precludes accounting for resource constraintsand management of risk. Enterprise-level analysisgenerally focuses on biophysical production, costs andprices. Due to the inability to account fully for risk at theenterprise level, analyses either assume risk neutrality orexamine risk efficiency. Steps in enterprise-level decisionanalyses are: (a) define the system and decision problem,(b) identify the range of viable decision options, developa realistic enterprise budget, (c) develop a stochasticbudget that accounts for climate variability, and (d)identify and evaluate superior strategies for climatologyand each forecast. I present an example of an enterprise-level analysis of maize management tailored to ENSOphases.

Eliciting Decision Structure and Decision Rules

David Letson

Jochec et al. (2001) effectively combined elements ofprescriptive and descriptive decision analyses in what isnow identified as a “participatory systems approach.”They used focus groups to (a) brief ranchers on theapproach and on seasonal climate outlooks, (b) elicit andconfirm decision rules in response to forecasts, and (c)verify the structure and results of an economic model. Themodeling approach combined forage prediction simulated

with a process-level simulation model using historicweather data, elicited decision rules, and a farm-leveleconomic accounting model. Rancher knowledge provedcritical for designing the decision analytic models,interpreting model results, understanding constraints toforecast use, and understanding rancher information needs.Whether or not you simulate ideal responses, start bylearning how climate-sensitive decisions are currentlymade.

Farm-Level Decision Analysis:Introduction

James Hansen

Climate-sensitive farm-level decisions include: (a) farmresource acquisition and allocation, (b) enterpriseportfolio / risk management, (c) managing interactionsbetween enterprises, (d) choice between farm andnon-farm activities, (e) choice between work and leisure,and (f) household consumption. To motivate thinking, Ipropose a series of questions related to each. I suggest thefollowing strategy. First, understand farmer goals.Second, inventory important decisions. Which aresensitive to the climate? What factors constrain each?Third, identify optimal (or risk efficient) strategies forindividual enterprises. Fourth, structure farm-leveldecisions and their determinants in a linear programmingtableau. Start simply and refine incrementally. Fifth,generalize objectives to consider, e.g., risk aversion.Finally, let farmers evaluate and refine the model. A farmlevel analysis cannot address market responses toaggregate decisions. Steep (inelastic) demand and a smallmarket relative to the aggregate production effects favornegative price impacts of forecast use.

Farm-Level Decision Analysis:Farm Land Allocation Case Study

David Letson

We present a case study of optimal management inresponse to ENSO information. The general problem is tochoose farming practices to maximize utility of expectedwealth, or its certainty equivalent. The value ofinformation (VOI) is the difference in certainty equivalentwith and without use of climate forecasts. The decisionmodel allocates farm land among 21 crop and management(fertilizer amount and planting date) alternatives tomaximize expected utility of year-end wealth, subject toland and labor constraints, and in response to pricevariability, risk aversion and climate variability. Theanalysis used synthetic weather data, crop simulationmodels, and stochastic prices. Maize is the favored cropfor favorable conditions, e.g., warm events and riskneutrality. Soybeans are favored in neutral and coldevents. Sunflower is a favored hedge, since its returns

21

have low variability and low correlation with those ofmaize. Diversification increases with risk aversion, butnot dramatically. Expected VOI is positive in the long-term, but in any given season may be < 0. The level andspread of VOI important to potential users. Omitting pricevariability may give misleading results.

Incorporating Market-Level Effects:Tomato Production Case Study

Carlos Messina

Although ENSO’s influence on Florida winter tomatoyields suggests that farmers might benefit from ENSOinformation, the small number of producers andgeographic concentration of production raises concern thatnegative price response might reduce or negate any

production benefits. A study to assess potential benefitsof ENSO information included participation of growersand extension agents; and retrospective, model-baseddecision analysis that linked historic weather data toprocess-level yield prediction and economic optimization.Optimal transplanting date and distribution of tomatoproduction between South Florida and Puerto Rico variedwith ENSO phase. Labor available for planting andharvest constrains responses to ENSO. The estimatedvalue of optimal use of ENSO forecasts for a single ha isabout $900 ha–1 y–1. If all farmers were to respond toENSO independently, reduced prices would cancelproduction benefits. However, if all South Florida tomatofarmers were to coordinate their actions optimally, theaverage benefit would be about $300 ha–1 y–1, or about$2,000,000 y–1 for the entire state.

You will use the built-in solver tomaximize certainty-equivalent farm income (CE) in a one-year decision period. CE is a nonlinear function ofvariability and risk aversion. You will look at sensitivityof the optimal solution to the degree of risk aversion.Solving the model for all years of weather data, andseparately for each ENSO phase allows you to calculatethe value of optimal use of the ENSO information. Forthe sake of simplicity, we will again not apply crossvalidation.

Module 4: Understanding Decision Makers

LECTURE SUMMARIES

Understanding Decision Makers

Peter Hildebrand

Farmers respond to climate forecasts using their ownindicators, and constantly make decisions about what toproduce, where, how and when. In addition to climate,they must also factor in market conditions, policies,household composition, and their own susceptibility toshocks. All these factors, and more, add up to verycomplex and diverse livelihood systems. We assume thatyou are interested in how to get farmers to respond toclimate predictions, how to get information to farmers,and how to understand farmers’ subsequent responses. Toreach these goals, it is necessary to understand whydecision makers make the decisions they do. IF yourforecasts are better than the farmers’ AND your suggestedresponses are better than the farmers’, then you need toknow how best to deliver the information, to whom, andwhen.

Relevant Questions

Peter Hildebrand

What information do you need before developingpredictions and making recommendations for highlydiverse smallholder farmers with scarce resources? Smallfarm livelihood systems: (a) are highly complex, (b) havea large number of enterprises, (c) have stronginterrelationships among enterprises, and (d) showincreasing dependence upon infrastructure with increasingpopulation pressure. Farming system diversity exists atscales ranging from continents to within-household. Thebiophysical environment, cultural norms, infrastructureand household composition influence diversity. It isimportant to understand who makes what decisions withinthe household and community. Key decisions include on-farm production (crops, livestock, non-agricultural) andreproduction (e.g., rearing children) activities, and off-farm activities (e.g., education, employment). Theportfolio, extent and seasonality of these activities areinfluenced by a range of biophysical and socioeconomicfactors.

Food Security in Developing Countries:Livelihood Activities and Portfolios

Corinne Valdivia

This session introduces the participants to the livelihoodsframework, a conceptual approach to understanding thecapabilities of people and their use of tangible andintangible assets resources and claims in making a livingin rural areas. The context in which individuals andhouseholds make decisions is also shaped by structures,institutions and climate. The session explains theseinteractions and how it can impact on coping with stressand shocks, and ability to make a living and improve it.From the conceptual framework, household livelihoodstrategies are analyzed with the economic portfolio model,evaluating the ex-ante and ex-post strategies to cope withshocks and stresses and adapt to climate variability.Finally the approach is applied to a case study on theidentification of profiles in the Bolivian Andes and howthis relates to access and use of information that improvescapabilities.

The Sondeo

Peter Hildebrand

The Sondeo, a reconnaissance survey method approachdeveloped in Guatemala to elicit information from farmersin a systematic way, is presented. In a Sondeo, livelihoodsystems are described, the agro-socio-economic situationof the farmer is determined, and the restrictions they faceare defined so that any proposed modifications of theirpresent technology are appropriate to their conditions. Ina relatively short time, it generates insights andinformation rarely obtainable in a formal survey.Generalizations beyond the sample interviewed arelimited. The Sondeo is characterized by a combination ofmethods used, fast turnaround time, close communicationbetween clientele and professionals, and aninterdisciplinary team approach. The presentationdiscusses the process and the applicability of thetechnique, in the context of the profiles of livelihoodsystems identified in the previous session.

Survey Design and Interpretation

Corinne Valdivia

This presentation focuses on the purpose andappropriateness of formal surveys in eliciting informationfrom farmers and their households. Formal surveysprovide a systematic way of obtaining information toanswer specific questions, in a manner that can be analyzedstatistically. Planning includes (a) specifying the questionsto be answered, (b) designing appropriate question contentand format, (c) defining respondents, (d) sample selection,(e) choosing interview method, and (f) establishinganalysis requirements. The order and manner in whichquestions are asked is important. Pre-testing is a necessarystep in the development of a formal survey. The mannerand order in which questions are asked is important,because it may influence the respondent’s answers. Anappropriate household survey is likely to includedemographic information, agricultural and non-agricultural activities, and climate. The advantages,constraints and purpose for the surveys are presented, aswell as the process to develop the survey, pretesting, dataentry, variable construction and analysis.

Introduction to Ethnographic Linear Programming of Small

Farm Livelihood Systems

Peter Hildebrand

This session describes the methodology to elicitinformation and describe a livelihood system, and identifythe livelihood strategies. Linear programming helps usunderstand highly-diverse livelihood systems, and servesas a basis for simulating household livelihood strategies.Simulating household livelihood strategies requiresethnographic data obtained with the participation of thefarmers. Ethnographic linear programming (ELP) helps usto design livelihood alternatives, and predict responses tochanges in technology, infrastructure, policy orenvironment. A linear programming matrix relatesresources, activities, goals, constraints and year-end cash.Household composition affects the amount and kind oflabor available, the amount of food required, and cashrequired for expenses. An example illustrates the stepsfollowed in developing a matrix for the LP model, and infinding feasible and realistic solutions that represent thelivelihood system.

EXERCISE SUMMARIES

Livelihood System Profiles

Corinne Valdivia, Peter Hildebrand

Objective: Learn to use information elicited from a keyinformant to develop a farm livelihood system profile,including capabilities, stores and resources, and claims andaccess, and the key external drivers.

Overview: The participants are divided in four groupswith a leader that is familiar with the agriculture of aregion. The regions identified correspond to India,Vietnam, Ghana and Ethiopia. The exercise consists ofdescribing a livelihood system, guiding the process by theconcepts of livelihoods, relevant questions, and portfoliocomponents described in the morning session. Each grouphas 40 minutes to develop a profile. Then these arereported to the whole group and discussed.

Livelihood System Matrices

Corinne Valdivia, Peter Hildebrand

Objective: Gain experience in quantifying a livelihoodsystem profile within a linear programming matrix.

Overview: The procedures to develop the matrix werepresented in a group session. The next step was anexercise to develop a matrix to represent a livelihoodsystem and identify strategies. The exercise consists ofdeveloping the matrix for an Ethnographic LinearPrograming exercise. After the group presentation thestudents broke into the working groups identified the daybefore to develop the livelihood systems, and used thissystem to develop a matrix with coefficients to understandthe objectives, activities and constraints. The second partof the exercise consisted in constructing the matrix in thecomputer and making it work. In the second part of theafternoon a member of each team was chosen to presenttheir matrix. “What-if” scenarios were explored, as two ofthe groups used the matrix to understand what wouldchange if some of the original conditions changed. Thelast part of the afternoon was intended for this exploration.

Scientific and Local KnowledgeSystems: Bridging the Gaps

Jere Gilles

Regardless of their education and sophistication,practitioners in a field approach knowledge quitedifferently than do scientists. The knowledge system ofpractitioners is termed local knowledge and is oftendistinct from traditional or customary knowledge.Priorities and emphases are different. Scientificknowledge tried to generalize across all settings and localknowledge concentrates on a particular place and time.The difference between these two knowledge systemsposes problems of translation and extension workers whooperate in the scientific tradition must learn to bridgebetween scientific knowledge and local knowledge if theyare to be successful. Given the different languages of thetwo systems, it is even more difficult to get feedback fromproducers. This session looks at these differences and triesto generate possible solutions.

Diffusion of Innovations: An Overview

Jere Gilles

What are the processes by which new ideas come to beadopted by most farmers in a population? This sessiongoes over the literature on the diffusion of innovation.The first distinction will be between awareness, trail andadoption because many programs encounter problemsbecause they do not distinguish between these threeelements. The second is between the different types ofadopters. The first people to adopt an innovation aregenerally very different from the remainder of thepopulation. Successful adoption by these "innovators,"though a crucial first step, will not assure the spread of aninnovation throughout all potential users.

26

The Role of the Innovation and the Social System in Adoption

Jere Gilles

Once we have the general principles of theadoption/diffusion model down, it is necessary to examinehow the nature of the innovation itself and the nature ofthe culture and social structure of a farming communitywill influence the adoption of an innovation and therelative benefits of that innovation. Basically the nature of

an innovation may influence the ability of people to try itout, to derive benefits from it and to sustain its use. Thesocial structure is also important because ultimately thewide diffusion of an innovation in a population dependson the networks of information sharing, power andinfluence that exist within a community. These factors donot influence the awareness of an innovation nor do theyhave an impact on the people who are the first to try a newtechnology. These networks are crucial for the widespreaduse/adoption of new technologies.

EXERCISE SUMMARIES

Networks

Jere Gilles

Objective: Identify possible bottlenecks in the flow ofinformation in participant countries to and fromagricultural field staff, using examples of weather andmarket information.

Overview: Each participant will draw a diagram of theflows of information to and from the agricultural fieldstaff person most likely to see farmers. Where does thisperson get information? What their resources if they wantmore information? How often do they use this source?How quickly does it flow? Once students have mappedout the networks, they should discuss possible bottlenecksand challenges. What barriers must be addressed to ensurethe flow of forecast information from its source tofarmers? This activity can be done by individuals orgroups of 2-3 persons who share a similar region, countryof origin, or farming system. These results will be sharedwith other small groups but probably not with allparticipants.

Diffusion Strategy

Jere Gilles

Objective: Gain experience in developing a strategy fordiffusion of climate forecast information and associatedtechnology.

Overview: The use of improved weather/climateforecasting techniques should help agriculture producersreduce the risks associated with weather. Your challengeis to identify a plan for the diffusion of the use of climateforecasting knowledge and an associated package ofdrought resistant crops to producers in your region. Firstdescribe the package of innovations that you would useand the communities of target producers. What challengesdoes the package of technologies and the social context ofagricultural communities pose for the innovation?Outline a plan of diffusion. What would be the targetcommunities? How would information be disseminatedand what steps would be taken to overcome the challengesposed by the technology and social settings themselves?Are there any preconditions, institutional changes thatwould be required before this program of diffusion couldbe initiated? This would be done by groups of 2-5participants who would present their results to the largergroup.

Module 6: Communicating Forecast Information

LECTURE SUMMARIES

Communicating Forecast Uncertaintyand Cognitive Anomalies

Peter Hayman

Like most of us, farmers tend to prefer categoricalforecasts that can be slotted into an IF THEN ELSE rule.For example, IF the season is going to be wetter thanaverage, THEN apply more inputs. Despite this preferencefor certainty, climate science can only offer probability. Inthis session we discuss several issues. First, whycommunicating climate science to end users requires beingclear about uncertainty. Second, why we need to workwith intermediaries to shift from the language ofchoice-consequence to choice-chance-consequences.Third, evidence from psychology that humans are poorintuitive statisticians. We will also cover the counterarguments that point out that as humans we aresurprisingly good at sorting though masses of data andmaking acceptable decisions. Finally we discuss ways tosimplify messages without “dumbing down” to categoricalforecasts.

Basic Principles of Decision Making

Galit Marcus

Rationality refers to consistent and systematicdecision-making. One might argue that people are neverirrational; some goal always motivates actions. Peoplemake decisions in a variety of modes, including: cost-benefit, recognition-based (including non-deliberative,stereotype-based, case-based and principle-based), role-based, reason-based, and affect-based. Cost-benefit andaffective decision making, for example, might lead toconsideration and selection of very different alternatives.Obstacles to good decision-making include: limitedattention, aversion to uncertainty, aversion to tradeoffs,conflict between motivation and cognition, and egocentricbiases. Limited attention contributes to excessivesensitivity to how a decision problem is framed, and toheuristics that simplify decision making but sometimeslead to poor decisions (e.g., availability,representativeness, anchoring). ’Good’ decision makingbenefits from using decision trees to structure a decisionin a manner that makes alternative actions, probabilitiesand tradeoffs explicit; and from creative problem solvinginvolving open-minded and sufficient (but not exhaustive)evaluation of goals, alternatives and probabilities.

Designing Communication Processesthat Help Decision Makers

Jennifer Phillips

Climate forecast information has value only if itinfluences actions by decision makers. The way in whichclimate information is communicated to the intendedbeneficiaries strongly influences the uptake and use of thatinformation. The common pitfalls of traditionaltechnology transfer include assuming that information isuseful before investigating the needs of users, ignoringsolutions already in place, and restricting informationexchange to one direction. Some lessons for addressingthese shortcomings in the communication process can bedrawn from the field of participatory development. Keyconcepts include interacting, facilitating, choice andadaptation. In practical terms, the use of discussiongroups is key, wherein everyone’s knowledge is respectedand ideas can be inspected, evaluated and accepted orrejected. Ideas for organizing discussion groups, the useof scenario-building as an activity, and integratingdiscussion groups with radio are presented here.

From Decision Support Systems to Discussion Support Systems

Holger Meinke

This talk illustrates how quantitative systems analysis, thatcombines simulation modeling with seasonal climateforecasting, can be useful in agricultural decision making.Quantitative systems analysis can help farmers replace“gut feeling” about their complex system with (a) harddata about the state of their system, and (b) probabilisticinformation about how the unknown can affect theoutcomes of decisions. Our participatory systemsapproach involving simulation-aided discussion withadvisers and farmers has led to the development ofdiscussion support software as a vehicle for facilitatinginfusion of forecasting capability into practice. WhopperCropper is an example, designed for farmer advisers.Whopper Cropper consists of a database of simulationoutput and a graphical interface for analyzing risksassociated with crop management options. Examplesillustrate how tactical responses to seasonal forecasts canincrease mean income. Although the approach does noteliminate the complexities of decision making, nor risksassociated with responses to a forecast, it does generatenew understanding of risks and opportunities. It providesquantitative data for meaningful comparison of options asa basis for informed discussion (“discussion support”).

Responding to Climate Forecasts: Using Scenarios in the Planning Process

Jennifer Phillips, Tahl Kestin, Cynthia Lawson

Objective: Explore and evaluate how predefined decisionscenarios communicate decision principles and improvedecision making under climatic risk. Participate in thereview of a web-based decision training module.

Overview: Trainees beta tested a web site,www.ccnmtl.columbia.edu/projects/iri/responding/index.html,designed to help people use forecast information indecision making. The site contains information on generalprinciples of decisions making, and a few case studiesillustrating these concepts. The assignment is to: (1) readthe web materials on scenario building and case studies,(2) develop your own case study, and (3) to fill out a briefquestionnaire regarding the usefulness of the site. Parts(1) and (2) will help you organize information that willhopefully lead to better decisions using forecasts. Part (3)will help us improve the site. Tutorials guide users toaccess IRI web-accessible resources, such as climate dataand forecast information. The three people who worked

most closely developing the materials were present toobserve and answer questions.

Crop Choice Simulation Game

Peter Hayman

Objective: Use a spreadsheet-based simulation game toexplore issues of using a skillful but uncertain forecast fordecision making.

Overview: The purpose of the game is to decide theportion of the farm that should be planted to a new higherreturn higher risk crop (wonder bean) and the portion toleave in the traditional lower return lower risk crop (stablecereal). There are three rounds. In the first roundparticipants hear from an agronomist how valuable thenew crop is and need to decide the portion to plant, thegame is cumulative and people start to learn fromexperience. The second round introduces the probabilitydistribution of the profit of the two crops and the thirdround involves seasonal climate forecasts.

Panel Discussion: Implementation Opportunities and Strategies

Panelists: Reid Basher, Hartmut Grassl, Sulochana Gadgil, Holger Meinke, Hassan Virji, Roland Fuchs, Peter Gregory

The panel discussion provided a forum for participants tointeract with experts from diverse backgrounds regardinglong-term implications of the training. Discussionsfocused on a few themes:

• Regional climate outlook forums,• Forecast timing and content,• Engaging stakeholders, and• Related programs of the sponsoring institutions.

Climate Outlook Forums

Periodic climate outlook forums in Africa and LatinAmerica have been quite successful in improving themethodological basis and authority of seasonal forecasts,raising awareness of seasonal prediction, and initiatingdialogue between climate and stakeholder communities.Virji polled the trainees to see how many haveparticipated in the forums, and challenged them to attendthose in their regions. Some of the discussion focused onthe relevance of forecast information that the outlookforums produce, and how effectively they reach andinvolve poor farming communities. Waiswa indicatedthat the process of trickling from policy makers down tofarmers tends to be slow. Basher cited a recentcomprehensive review of the climate outlook forumprocess, the challenges involved in sustaining them, andthe prospects for reducing costs throughvideoconferencing.

Forecast Timing and Content

Grassl asked what forecast time scales are relevant, andchallenged participants to use the full range ofinformation, from daily weather forecasts to globalchange scenarios, that are available from internationalclimate institutions. Romero stressed the need to focuson critical periods for crop response, such as flowering.Waiswa indicated that farmers in eastern Africa wantforecasts of rainfall onset date, and complained that therainy season sometimes starts before climate outlookforms in the region. Adiku later reiterated the importanceof predictions of onset date, and emphasized the value ofcontinuous forecast updates within the season. Accordingto Singh, Indian farmers are concerned about breaks in themonsoon, and demand more information about within-

season variability. The group discussed the challenge offorecasting onset dates, and the potential for optimizingthe timing of forecast delivery and climate outlookforums. Gadgil first asked whether participants wereprepared to use relevant predictors other than ENSO.Later discussion emphasized the potential for satelliteremote sensing data, including spatially-contiguousestimates of rainfall and stored soil moisture, to addvalue to seasonal forecasts. According to Basher, the IRIprefers to build regional capacity, rather than tailor itsown global forecasts to local user need.

Engaging Stakeholders

Meza proposed that communication between farmers andresearchers is inadequate, and discussed the challenge ofmaintaining interest and learning during neutral years.Boer, Biru and Adiku called for greater efforts to equipextension personnel to function as intermediaries incommunicating forecast information. Gadgil counteredthat researchers need to interact directly with farmers tolearn from them, and not just rely on extensionintermediaries. Adiku highlighted the cultural andinstitutional barriers that sometimes limit directinteraction between researchers and farmers. Birusuggested that climate outlook forums may be a vehiclefor engaging farmer groups and extension programs. Theperceived need to effectively engage farming communitiesled naturally to a discussion of training for extensionpersonnel and for farmers. Fuchs-Carsch suggested theInternational Service for National Agricultural Research(ISNAR) as a potential starting point for building capacitywithin national agricultural research systems. Basherurged participants to also actively engage policy makersand senior scientists.

Related Programs

Panelists summarized relevant capacity buildingopportunities at START (Fuchs), the GlobalEnvironmental Change and Food Systems Program(GECAFS) (Gregory), CLIMAG projects in West Africa(Virji) and Asia (Meinke), and climate applications at theIRI (Basher).

WORKSHOP EVALUATION

Summary

On the final day of the workshop, individualquestionnaires and a self-directed group evaluationprocess gave participants the opportunity to evaluate theirexperience. The evaluation questionnaires combinednumeric and open-ended questions about the overalldesign and implementation, individual training modules,and the proposal development and evaluation process.Numeric results are presented as histograms on thefollowing pages.

Open-Ended Questions

The first open-ended question was, “What was the mostvaluable aspect of the workshop?” Several answersrelated to integration – the conceptual design of theworkshop; combination of climate science, agriculture andsocio-economics; combination of theory and exercises;how to integrate various tools; how to make forecastsuseful to farmers. Others focused on people – the qualityand experience of faculty; interactions with faculty, IRIclimate scientists and other participants. Severalparticipants found the training and support for projectproposal development the most valuable aspect. Othersidentified a variety of particular topics.

Four open-ended questions solicited perceived weaknessesand proposed improvements. Topics identified as needingmore attention include: dynamic climate models, climateforecasting, downscaling, use of climate model output,crop modeling, understanding and modeling decisionmakers, communication, and integrating forecasts withfood security. Topics identified as needing less attentioninclude: dynamic climate models, climate forecasting,relationships between empirical and dynamic forecastmodels, crop modeling, analyzing decision makers, andcommunication. The diversity of answers clearly reflectsthe diversity of needs, interests and backgrounds of theparticipants. Although the target audience was restrictedto agriculture and food security professionals, theparticipants still brought a rich diversity of cultural,educational and professional experience to the Institute.

Participants offered a range of suggestions for improvingthe training. Several related to the exercises. Participantsdisagreed about whether there were too many or too fewexercises. However, several cited problems completingexercises in a manner that fostered learning. One proposedremedy was after-hour access to computers equipped withthe software necessary to complete exercises. Suggestions

related to the intensity of the materials included: reducingmathematical rigor; screening participants to ensureappropriate background; provide more introductoryreading material well in advance; splitting the curriculuminto two workshops; and scheduling time for interactionwith faculty and IRI scientists. Other general suggestionsincluded: introducing social science concepts and methodsearlier; allowing participants to analyze their own datasets; keeping participants in one computer lab; and makingsoftware tools available to follow-up projects and homeinstitutions. The diversity of suggested changes to thebalance of topics included in the curriculum reflect thediversity of participant interests and backgrounds.

Quantitative Results

Participants rated many aspects of their experience on five-point numeric scales. Results are presented as histogramsin the next section. Most agreed strongly that theworkshop was personally valuable, and showed moderateagreement that it met its objective of equipping them tobring climate information to bear on their institutions’ongoing work. Nearly all felt that the level, scope andbalance of material and duration of the workshop wereappropriate. Lectures, exercises and faculty were generallyrated as effective. All trainees considered proposaldevelopment and evaluation activities to be valuable.They were, however, divided on whether time spent onproposals detracted from learning. The proposalworkshop was regarded as the most effective component,and the peer review activities the least effective componentof the proposal development process during the workshop.

There was no clear segregation among modules in termsof accomplishing objectives, relevance, comprehensibility,or the challenge to think in new ways. Module 1influenced more proposals than did the other modules.Responses suggest that Modules 1, 2 and 6 are most likelyto influence participants’ ongoing work.

Group Evaluation

Trainees conducted and summarized a group workshopevaluation. The group rated the training workshop as asuccess overall. Their report highlighted “the remarkableblend or disciplines and topics and the logical linkagesbetween successive components.”

They expressed several concerns that were generally

“The training course is very useful, and has provided ustheoretical and a little practical knowledge in climateforecasts and application in agriculture. The staff areexcellent, very supportive and enthusiastic. Logistics wereperfect.”

“The workshop was very well planned. The combination ofclimate science with agricultural and socio-economicsciences is a very good blend.”

“Meeting other participants, faculty, IRI and STARTmembers was very valuable. We could exchange ideas andexperiences and make contacts. I hope these relationshipswill be strengthened over time. This training will be veryvaluable in boosting my research and career.”

“The workshop is very well organized, and I appreciateJames Hansen and other faculty for their help sincerely.”

consistent with those raised in the individualquestionnaires. First, the time constraint limited theirability to fully assimilate the materials. Theyrecommended sending background reading materialsearlier. Second, participants generally wanted moreemphasis on practical methodology, and offered severalsuggestions related to exercises. The third issue related to

understanding climate data formats and access proceduressufficiently to allow them to use the IRI Data Libraryeffectively in their projects and ongoing work. Fourth, thereport cites issues of policy, markets and food securityresponse that participants would like to see receive moreattention. The group identified several additional topicsthat would be of interest in future training.

“Discussions highlighted theremarkable blend of

disciplines and topics andthe logical linkages betweenthe successive components.”

Group Evaluation

Moderator: Francisco MezaRapporteur: Sibiry Traore Pierre

Participants believe that IRI,START and their partners met thedifficult challenge of organizingthis workshop. Discussionshighlighted the remarkable blendof disciplines and topics and thelogical linkages between thesuccessive components. Overall,participants agreed that theorganization of the ATI was asuccess, with a particular mention for the facilities, judgedexcellent.

Although the workshop duration appears to be appropriate,the time constraint has been pointed out by severalparticipants, for which proper assimilation of informationand technical skills received during lectures and exerciseswas being hampered by proposal development activities.The group recommends that background material be sentto participants much earlier prior to workshop kick-off inorder to enhance preparedness and reduce time pressureduring the workshop itself.

Participants feel that more emphasis should be put on thepractical side of the training. These include (but are notlimited to): more time and faculty allocated to exercises(with more flexibility to access computer rooms afterregular working hours), allowing for more discussions andsupport during the exercises sessions; increased relianceon case studies (instead of “blind” directive guidelines andhandouts that one follows rather “mechanically” – the lastweb-based exercise on 07/25/02 was the only oneinvolving case studies and this approach would have alsobeen very useful earlier in the workshop); possible use ofparticipants’ own data (which would need to be brought bythe trainees at the workshop); more exposure and trainingon data formats (this topic was not specifically scheduledand had to be squeezed in on 07/25/02; it would have beenuseful to include it early in the training process).

Participants think that the issue ofdata access needs to be included inthe training curriculum, as everyfollow up project will rely onsources of climate forecasts to anextent or another. It was suggestedthat the ATI coordinators sendsome electronic materialdocumenting IRI climate dataaccess procedures.

The issue of food security has also raised muchdiscussions. Some participants suggest that food securityper se has not been given enough attention despite itsexplicit mention in the theme of the ATI. The trainingcurriculum could include topics related to markets andpolicies as they are major factors acting on food securityalongside climate variability. The group recommends thata few policy makers be also invited to serve as lecturers inthe future. A participant suggested that ‘climate variabilityand food production’ would better describe the actualcontent of the ATI.

Other suggestions include: the need for a role-playinggame in the module on communicating forecastinformation; the need to expose trainees to alternativeapproaches for crop yield forecasting (some feel there istoo much reliance on process-based crop models – simplerempirical models could be other options to consider);finally, several participants suggested that opportunitiesfor meetings and discussions with actualpractitioners/users of climate forecasts (e.g. local farmers)should be explored for inclusion in the activities of thetraining institute.

Beyond these recommendations for further improvement,the group acknowledges the efforts made by the organizersand faculty for successful conduct of the training institute.

PROJECT SUMMARIES

Exploring Options for Improving CropProductivity Within Some Farming Zones of Ghana Using Coupled Climate-Crop Models

Samuel G.K. Adiku

Mentor: James W. Jones

This project seeks to develop a climate-based decisionsupport system to guide agricultural workers (farmers,extension advisors and policy makers) in planning theirwork, with the view of improving the productivity ofmaize and peanut in farming areas within southern Ghana.The proposal is set out in three phases: First, theknowledge (both indigenous and formal) of agriculturalworkers in climate variability and their planning methodsto offset bad seasons or exploit good seasons will beinvestigated. Second, models of maize and peanut inconjunction with long-term historical climate data will beused to investigate the problem of yield variability at ten(10) selected farming sites in southern Ghana. Third, twoclimate forecast techniques will be evaluated for theirvalidity to forecast the yield of peanut at one of thefarming sites. One technique will use historical climatedata of analogue years corresponding to three ENSOphases (El Niño, Neutral and La Niña) to simulate peanutyields in hindcast mode. The other technique will useclimate data output from a stochastic weather generator(e.g., WGEN) whose parameters are conditioned uponENSO phases, to run the peanut model. In both cases, thehindcast yields will be cross-validated and compared withhistorical yields collected from the Ministry ofAgriculture, Ghana. An assessment of the skill of theforecast method will be based on correlation coefficientand the root mean square error.

Early Climate Warning to the AndeanFarmers: Linking Seasonal Forecast

Information to Integrated GIS and Biophysical Models

Guillermo A. Baigorria

Mentor: Corinne Valdivia

Mountain areas present harsh environment, poorinfrastructures with difficult access and many hazardsrelated to climate and terrain. Climate forecasts at aglobal scale are not useful due to their low resolution.Therefore, there is the necessity to develop forecastingtools that represent the potential concerns of farmers in

order to integrate this information into their agriculturaldecisions. The project will combine the knowledge onseasonal-climate forecasting and geospatial modeling tocreate a support system for decision-makers. The projectwill develop a statistical downscaling method, linking theclimate forecast from Global Climate Models with the GIS& Biophysical models Laboratory software (GABP-LAB).This software makes use of the Water Erosion PredictionProject (WEPP) and the Decision Support System forAgrotechnology Transfer (DSSAT). Both are in theprocess of being validated for the Andean highlands. Thecase study will be held in the La Encañada Watershed inthe northern Andes of Peru, ranging between 2500 to4000 m.a.s.l. Simulated crop production maps athigh-resolution levels will be produced using seasonalforecasts, and traditional and alternative managementfarmers’ portfolios. Outputs will be presented to farmersbefore the cropping season. The acceptance by farmerswill be analyzed comparing both, the decisions proposedby the model versus farmers decisions.

Designing a Climate Sensitive DecisionSupport System for South Eastern (Somali

Region) Pastoral Areas of Ethiopia

Ngist Biru

Mentor: Maxx Dilley

Pastoralists in Ethiopia have faced repeated severedroughts leading to massive livestock losses and humansuffering. The limited ability of pastoralists to cope,coupled with poor early warning systems contributed tothe 1999-2000 humanitarian crisis. Save the ChildrenUnited Kingdom has been working with variousstakeholders to improve the early warning system inpastoral areas, focusing on the Somali Region. The systemincorporates the Household Food Economy Approach, butdoes not use available remote sensing or seasonal climateprediction information. Improved information could beused by the government, NGOs, donors, and also by thepastoralists. The project will incorporate both remotely-sensed rainfall and NDVI data, and climate predictioninformation into early warning in two zones of the Somaliregion, and assess the resulting benefits. The food securityofficers of the two zones will be trained to processrelevant satellite imagery. The principal investigator willfollow up on the incorporation of the remote sensed dataand forecast information in monthly bulletins in a way thatis understandable by users. A survey of government,

Astochastic climate data generator model to manageclimatic data limitation problems in Indonesia and its useto assess year-to-year and site-to-site variability of soilwater condition and potato production in the Pengalengansub-district (Bandung District, West Java) will beevaluated. Evaluation of the use of stochastic climaticdata generator model conditioned for ENSO phases toassess the variability of soil water condition and potatoproduction at Pengalengan will also be conducted.Options for supporting farmers in decision-making on thechoice of cropping strategies based on climate forecastoutcomes, and assisting agriculture extension workers andlocal agriculture staff to use climate forecasts to guideagricultural planning will be explored andoptions/approaches to connect dynamic climate modeloutput to agricultural simulation models forbenchmarking and impact assessment will be provided.

An Early Warning and Visualization System toIndicate the Three Monthly Status and

Impact of the El Niño Southern Oscillation onNamibia

Albert Calitz

Mentor: Willem Landman

This project will develop a relay system that will localizethe seasonal precipitation forecast of the InternationalResearch Institute for Climate Prediction (IRI), forNamibia. The system will show the area in Namibiaaffected by the El Niño Southern Oscillation (ENSO) in a25 X 25 kilometer grid and will visualize the seriousnessof the impact in terms of a rainfall index. This system willserve as an early warning system for ENSO relateddroughts. The output will be used as input to strategicplanning of drought aid and agricultural productiondecisions. It will provide an important and much-neededplatform for mitigating the effects of extreme ENSO

events. It will aid in directing policies and activities tomanage La Niña-related floods and El Niño-relateddroughts and water shortages, and provide input fordetecting the overuse of farmlands and the misuse ofgroundwater.

The overall goal of this project is to contributetoward improvement of the economic condition of Isabelacorn farmers by enhancing the stability of corn productionsystems in the province through the use of climate forecastproducts.

Application of Seasonal ClimateForecasts to Predict Regional Scale

Crop Yields in South Africa

Trevor G. Lumsden

Mentor: Emma Archer

The high inter-annual variability in South African climate,and resulting high variability in crop production, hasimplications for food security in the country, in particular,amongst resource-poor farming households. Theusefulness of available seasonal forecasts couldpotentially be enhanced if they were translated intoforecasts of crop yields through application of a cropmodel. The application of a crop model allows fordifferent management scenarios to be explored, and for anoptimum to be determined. The objectives of this researchproject include the linking of a crop yield model todownscaled seasonal climate forecasts derived from adynamical climate model, thus enabling the generation ofcrop yield forecasts for various agricultural regions inSouth Africa. These crop yield forecasts could be used in

Alemu Asfaw Manni

Mentor: Maxx Dilley

The tragic death of many people in the recurrent Ethiopiandrought demonstrates the region’s vulnerability to climatevariability. By studying climate variability and makingclimate information palatable to farmers and other users,we hope to empower them to mitigate the consequences ofnatural hazards, particularly drought, through better-informed decision making. The objectives of this projectare to (a) increase access to climate information productstailored to farmers (including pastorals andagro-pastorals), (b) integrate climate information with theHousehold Economy Approach, and (c) create awarenessof opportunities to use climate information in farmingdecisions. The project will generate knowledge, increasethe use of climate information, and identify ways in whichinformation products tailored to user needs can be appliedto reduce vulnerability and enhance preparedness. Projectactivities will include: timely dissemination of forecaststailored to user needs, dissemination of climateinformation linked with other food security-relatedvariables to relevant user groups, and collection andarchiving of relevant data. This project will demonstratethat forecasts can be effectively tailored to the needs ofusers, with a focus on pastoralists and agro-pastoralists.Lessons learned can be extrapolated to other parts of thecountry and other sectors of the economy.

Where and When Do We Need Water? Development of a Regional Crop Yield and

Water Demand Model Based on Sea SurfaceTemperature Forecasts

Francisco J. Meza

Mentor: Guillermo Podestá

The operation of water resources in regions of largeclimatic variability represents one of the major challenges

of modern society. Competition for water acrosseconomic sectors, and natural variability of the system canimpose severe restrictions on water supply. For thisreason, the need for integrated and efficient watermanagement policies has become increasingly important.The central valley of Chile shows a significant ElNiño-Southern Oscillation (ENSO) climate footprint onits climatic regime that can affect both water demand andsupply. This feature and the current skill of climateforecast models suggests that there is valuable informationthat can be incorporated into the decision making processin order to explore efficient water management strategies.The main objective of this research is to characterize themain water components of the agricultural hydrologicalcycle as well as the possible crop yield outcomes ofirrigated sectors under the ENSO scenarios. By combiningcrop models and climatic variability information performan exploratory analysis of the applications of climateforecasts for water management purposes for the MaipoRiver Basin. This project will result in the developmentof a regional model to assess water demands, crop yieldimpacts and risk profiles based on ENSO information andwater availability.

Application of Climate Predictionin Rice Production in the

Mekong River Delta, Vietnam

Thuan Nguyen

Mentor: Michael Manton

The Mekong River Delta is the largest rice producing area,and one of the most densely populated areas of Vietnam.The majority of the population depends entirely onfarming for their livelihood. Water deficiency and waterexcess associated with seasonal climate variability lead toa remarkable variability in rice production. Much of thisvariability appears to be related to ENSO. Seasonalclimate forecasts would help agricultural workers andfarmers plan for the coming season, and prepare forunfavorable climate conditions. The research project aimsto identify the impacts of ENSO phases on rainfall andtemperature characteristics over Long An province.Downscaled climate forecasts for the province will beproduced and disseminated to the agricultural sector.Seasonal climate forecasts will be incorporated into a cropyield simulation model to generate crop yield forecasts,which will then be evaluated.

to Prosperity? Farmers’ ParticipatoryApproach to Manage Climate Variability

V. Nageswara Rao

Mentor: Sulochana Gadgil

We plan to collect the long-term historical weather datafor Anantapur and Mahboobnagar sites, and identifypredictors that have good physical correlations forpredictand (rainfall) of the regions. Appropriate statisticaldownscaling techniques will be employed to predictclimate with dependable skill at local scale, and generateviable cropping options through APSIM modeling for useby farmers. A survey will be conducted to assess farmers’perception on relevance of climate forecasts in farmingdecisions. In partnership with NARS collaborators, weshall present to farmers the possible prediction skill ofclimate for these two regions as against historicalobservations, and the ensuing season’s forecast of climate.Besides, we will discuss with farmers, model-basedcropping options using yesteryears’ climate, which mighthave benefitted farmers, and options available withpredicted climate for the coming season. Forty farmersfrom four villages in two districts will be identified byexpression of interest, to participate and evaluate croppingoptions decisively in the study. During the crop season,observations will be recorded on farmers’ decisionsregarding cropping options, their input strategies, andreturn on investment to farmers who made use of climatepredictions. Farmers’ participation and discussions would

help evaluating the value of climate predictions to drylandagriculture in the region. As long-term benefits, we wishto create a local hub for climate prediction expertise byproviding training on downscaling techniques tocollaborators, and awareness among farmers aboutpotential gains as well as risk minimization throughapplying climate forecasting and crop modeling inagriculture.

Towards the Development of a SpatialDecision Support Systems (SDSS) for the

Applicationof Climate Forecasts in Californian

and Uruguayan Rice Production Systems

Alvaro Roel

Mentor: Walter Baethgen

Although forecasts make predictions of climate variablebehaviors for large regions of the world, these regions arenot uniform. Nevertheless, seasonal forecastrecommendations are traditionally applied as uniform invast regions. These had determined that in many situationsin some areas of these regions forecast recommendationswere suitable while in others not. A pilot project isproposed to evolve a system for the effective applicationof a seasonal climate forecast, which can address thenatural spatial variability in growing conditions thatcontrol productivity in rice ecosystems. The ultimate goalis to be able to predict for a given forecast how is going tobe the yield spatial structure within a field undertraditional management and according to the SDSS whatshould be the strategy to follow to maximize yieldproductivity under this climatic scenario. Therefore theOverall objectives of this project is: To integrate the "stateof the art" of the scientific knowledge regarding seasonalclimate forecast, crop simulation models and site-specificfarming into a Spatial Decision Support System for therice production systems of California and Uruguayan riceproduction sectors to decrease their vulnerability to interannual climatic variability.

Application of Seasonal Climate Forecastfor Sustainable Agricultural Production

in Telangana Sub-division of Andhra Predesh, India

K.K. Singh

Mentor: James Hansen

A major part of the population in the semi-arid AndhraPradesh lives in rural areas, where per capita income isvery low and agriculture is the main source of livelihood.In the absence of adequate irrigation facilities, rainfall isthe most critical element dictating productivity. An erraticrainfall distribution in space and time, associated droughtsand floods, and other socioeconomic factors force manyresource-poor farmers to migrate to urban areas to seekemployment. Early warnings based on seasonal rainfallforecasts can help farmers to adjust crop managementstrategies to minimize impacts of malevolent climate and

maximize benefits of benevolent climate. This project willevolve a system for the application of the seasonal climateforecasts to rainfed agriculture in the semi-arid areas ofAndhra Pradesh, India. We will select two districts astarget areas for climate forecast application. At theselected locations, we will explore crop managementscenarios (of farmers’ choice) based on climate forecasts.Finally, we will seek to integrate the use of seasonalclimate forecasts with the Agrometeorological AdvisoryService (AAS) of the National Centre for Medium RangeWeather Forecasting (NCMRWF). Outcome of theproposed research will equip and strengthen the AASsystem of NCMRWF with scientific tools andmethodologies that can be used for the potentialapplication of seasonal forecasts in agriculture in otherzones.

Coping with Climate Risk in China: Developinga Food Security Warning System Using

Seasonal Climate Forecasts

Fulu Tao

Mentor: Hartmut Grassl

The climate in China is highly variable due to influencesof Atmosphere/Ocean oscillations (such as ENSO,monsoons, etc.). The agriculture in China is highlyvulnerable to this climate variability because manycropping systems are rain-fed with low technicaladaptation. It is becoming clear that skill in seasonalclimate forecasts offers considerable opportunities tofarmers via its potential to improve yields. This projectaims to develop a food security warning system usingseasonal climate forecasts as input for food productionestimates and provision of adaptation options, ahead ofcrop seasons. Firstly we use a crop model to simulate thetime series of yield anomalies during the last decades.Then we analyze the correlation between the yield anomalyand seasonal climate anomaly using a multivariatestatistical model; finally we apply the statistical relationsto predict yield variability for the next season withseasonal climate forecasts as inputs. The predictions(probability estimates) will be used to discuss adaptationoptions with farmers.

Bytes for Bites: Translating Climate Forecastsinto Enhanced Food Security for the Sahel

Sibiry Traore Pierre

Mentor: Neil Ward

Climate variability is an urgent problem in the Sahel. Pastdramatic droughts and evidence of decreasing rainfall callfor new adaptative strategies to meet food requirements ofthe growing population living in these fragile and changingproduction systems. Modern science systems analysis andsimulation models have the potential to address thischallenge. Crop yield forecasts can be developed byappropriate combinations of climate and crop modeling,and incorporated into farmers practices. To achieve this,spatial and temporal scale constraints can be tackled withremote sensing techniques to increase local predictionskill. Use of leading climate and crop models will allowquantitative analysis of sorghum, maize and cottonresponses, and subsequent identification of optimal cropmixes under variable climate patterns in southern Mali.Outputs will include a decision-support matrix forproducers to minimize climatic risk, an evaluation ofcurrent forecasting skill and a digital land surface schemeof the region, and a method to apply climate forecasts toidentify production options in sudano-sahelian agriculture.Exposure of farmers and NGOs to products generated willprefigure the implementation of a full-size projectinvolving all partners along the information chain, withsensible impact on agricultural production expected byyear 2010.

Climate Information for Food Security:Responding to Users Needs

of Climate Information

Milton Michael Waiswa

Mentor: Jennifer Phillips

Currently climate scientists are able to use sea surfacetemperatures to forecast shifts in probabilities of rainfallamounts over a three-month period. Although this type ofinformation is important, the first major climateinformation needs of the farmers is knowing, at adequatelead times, the timing of the expected onset of seasonalrains. As a coping mechanism, farmers attempt to usetheir traditional indicators, particularly local winds andtemperatures, to forecast this important climate element.However, identification, validation and improvement ofthese indicators have not been done. Therefore this studywill identify details of traditional usage of temperature andwind information for forecasting onset of seasonal rains;validate the traditional environmental indicators for onsetof seasonal rains; develop statistical models forforecasting of seasonal rains and disseminate researchfindings. Identification of usage will be achieved throughconducting individual and group surveys of farmers inEastern (Tororo), Lake Victoria basin (Jinja), Central(Namulonge) and Western (Masindi) Uganda. Validationof environmental indicators will be based on the climatedata from synoptic weather stations in the four regions.Model development will be achieved by statisticalregression of validated temperature and wind indicatorswith rainfall onset dates formatted in pentads. Operationaluse of findings will be initiated through a stakeholders’workshop.
