Geoinformatics for nourishing drylands
At a global perspective drylands :
- Cover 41 percent of the Earth’s surface
- Support 30 percent of the world’s population
- Support 50 percent of the world’s livestock
- Grow 44 percent of the world’s food
- Are home to ...
Actual Evapotranspiration of rainfed areas in 2002
Evapotranspiration was determined using the methodology proposed by USGS’s Simplified Surface Energy Balance.The Actual Evapotranspiration (AET, mm) estimation was done using MODIS 1km (thermal infrared band resolution) ...
Agricultural water productivity for irrigated areas in 2002
Agricultural Water Productivity (WPM) (kg/m3) was determined for each pixel by dividing crop productivity (kg/ha) raster layer by seasonal crop water use in terms of actual evapotranspiration (m3/ha) raster layer.The WPM ...
Agricultural water productivity for rainfed areas in 2002
Agricultural Water Productivity (WPM) (kg/m3) was determined for each pixel by dividing crop productivity (kg/ha) raster layer by seasonal crop water use in terms of actual evapotranspiration (m3/ha) raster layer.The WPM ...
Agricultural water productivity Hotspots of irrigated areas in 2008
The Hot spots of high and low water productivity was done by classifying the biophysical agricultural water productivity (kg/m3) layer into three classes: (i) High water productivity which includes values exceeding 1.0 ...
Food security in changing Arab environment
The Arab region has the largest food deficit in the world, due to the strained natural resource base and vulnerabilities to climate change implications, which put tremendous pressure on achieving food security. During the ...
Agricultural water productivity Hotspots of rainfed areas in 2006
The Hot spots of high and low water productivity was done by classifying the biophysical agricultural water productivity (kg/m3) layer into three classes: (i) High water productivity which includes values exceeding 1.0 ...

Crop yield of rainfed areas in 2006
Crop yield layer where derived from MODIS gross primary productivity (GPP) layer as a production efficiency model approach that estimates crop growth from intercepted photo synthetically active radiation and light use ...
