2. Environment and Natural Resources Service 2. Environment and Natural Resources Service (SDRN)(SDRN)

It’s the integrated response to FAO’s environmental and natural resources programme requirements.

SDRN deals with sustainable development and natural resources and environment management issues in order to:• develop spatial information infrastructures that enable information access, sharing and lower costs; • promote integrated data and information use for food security and sustainable development; • develop methodologies, guidelines and policies for resource management and environmental monitoring.

SDRN has a multidisciplinary team of experts in remote sensing, geographical information systems,agro-meteorology, environment, energy, ecology, and economics.

GIS is used to integrate, process, analyse and display digital spatial and non spatial data. Layers of thematic information can be integrated to provide new insights into sustainable development problems.

Layer 1: Hydrography rivers and lakes.

Layer 3: Infrastructure

Original data can be from a range of projections and scales.

Layer 4: Soils

Layer 2: Elevation contours

In this example, many thematic layers were integrated to obtain a GISinformation infrastructure for Burundi.

Layer 5: Major land-cover types

3. Geographic Information System (3. Geographic Information System (GISGIS))GIS refers to computerised information storage, processing and retrieval systems, specifically designed to cope with spatial data and its corresponding attribute information.

Several layers are combined in thisGIS output. The 3D effect is generated by the GIS from the elevation data.

4. Advanced Real4. Advanced Real--Time EnvironmentalTime EnvironmentalMonitoring Information System Monitoring Information System

((ARTEMISARTEMIS))Since August 1988, ARTEMIS has been operationally receiving, processing, archiving and disseminating low-resolution remote sensing imagery in support of FAO’s programmes on early warning for food security, migrant pest anddisease control.

The ARTEMIS system was implemented by FAO in close co-operation withNASA Goddard Space Flight Centre, USA, the National Aerospace Laboratory (NLR) of the Netherlands and the University of Reading, U.K. with funding support from the Government of the Netherlands.

The ARTEMIS archive contains products derived from four different series of satellites by a number of processing centres and are available at daily, 10-daily, bi-weekly and/or monthly intervals.They can be seen at http://METART.FAO.ORG

SEDI is a simple and straightforward method for “assisted” interpolation. The method can be applied to any parameter of which the values are available for a number of geographical locations, as long as a 'background' field is available that has a negative or positive relation to the parameter that needs to be interpolated.

Three requirements are a prerequisite for the successful application of the SEDImethod:� The availability of the parameter to interpolate as point data at different geographical locations (e.g. rainfall, potential evapotranspiration, crop yields)� The availability of a background parameter in the form of a regularly spaced grid (or field) for the same geographical area (e.g. CCD, NDVI, altitude).� A relation between the two parameters (negative of positive; rainfall/CCD is positive, PET/altitude is negative). A Spearman rank correlation test can reveal whether a relation exists, and how strong this relation is.
