[Day 2] Center Presentation: CIMMYT

GIS Activities at CIMMYT

Juan Arista

CSI Meeting, ILRI Campus, Nairobi, March 31 – April 4th 2009

Outline

● Wheat Stem Rust Monitoring

● DTMA

● Wheat Atlas

● Wheat Blast - an emerging new threat?

Wheat Stem Rust Monitoring

● Development of standardized

field protocols + geo-referenced

data collection

● Centralized data base

● Improved web-based information

tools

Capacity Building

● 3 Regional training workshops

● 100 GPS units distributed (29 countries)

● Standardized protocols

Uzbekistan, June 2008● → Rapidly increasing flow of field data (KARI, EIAR, AREA)

On-line Information Tools

● RustMapper (Google Earth/web-browser)

● Near real-time: sites, winds, wheat,

susceptibility

Ug99 Pathway

● Known movements are following winds

● Yemen – most likely source for Iran

● Highly likely that Ug99 went undetected in southern Iran or southern Iraq?

● High potential for multi-directional dispersal from Iran

● New variants likely to follow a similar route?

DTMA

● All Socio-econ data geo-referenced, compiled

and summarized

● Drought frequencies – By maturity groups and

growth stage, frequencies for last 7 years

● Improved seed demand models in development

DTMA – New Tools

● Customized visualization tool based on Google

Maps / Google docs developed

● Google Earth version (browser) – coming soon

Where the Economists are working

DTMA – Trial Sites Tool● Site checking / editing tool

● Interactive tool – real-time links into MySQL data

base

● Correct site locations – extract data for GxE

Wheat Atlas

● An integrated web-based compendium of useful

geographically-based wheat information

● Countries in phase 1: Algeria; Egypt; Ethiopia;

Morocco; Sudan; Tunisia; Turkey

● Draws information from CIMMYT international

trial site dbase, FAOSTAT ..

● Interactive charts, maps, tables – region /

country / site level

Wheat Atlas

Wheat Blast – An emerging threat

● Wheat blast caused by Magnaporthe grisea

● First report Paraná, Brazil in 1985

● Now found in Brazil, Paraguay and Bolivia

● Severe yield losses (90-100%)

● NO KNOWN SOURCES of RESISTANCE

● Lack of epidemiological knowledge

● Seed-borne (others?)

● Where might be at risk?

Potential in Other Regions

● Climate similarity

• Maximum Temperature

• Minimal Temperature

• Rainfall

Key Areas

● Ethiopia

● South Asia

● North America

● Need to keep a close watch on this disease
