Improving Water Productivity in Agricultural Systems, April 24 – May 12, 2016
Water is the major limiting factor for agricultural production in the dry areas of Central and West
Asia and North Africa (CWANA). Agriculture accounts for around 80% of water consumption in the
region, however, the rapidly ...
Agricultural water productivity for rainfed areas in 2006
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 ...
WLI 2017 Project Narrative
WLI 2017 _Project Narrative
Scenarios and analysis
Three scenarios were examined for the normal year of 2006. The scenarios are based on raising
agricultural water productivities to various levels by more investment, improving water management,
agricultural practices and ...
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 ...
Rainfed Agriculture and Food Security in Dry Areas
The world’s ability to produce enough food to feed the growing population is further constrained by water scarcity, particularly in dry areas. Water is an increasingly scarce resource and the FAO estimates that nearly 1.8 ...
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 ...
Actual Evapotranspiration of rainfed areas in 2008
Evapotranspiration was determined using the methodology proposed by USGS’s Simplified Surface Energy Balance. The Actual Evapotranspiration (AET, mm) estimation were done using MODIS 1km (thermal infrared band resolution) ...
Crop yield of irrigated areas in 2002
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 ...
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) ...
