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 ...
Responsiveness of chickpea to climate change
Appropriate changes in the genetic options are needed to cope up with the changing climate and farming
system to ensure food security and sustainable cereal production for the ever growing populations in
developing world. ...
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 ...
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 ...
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) ...
Quantification of Agricultural Water Productivity at Field Scale and Its Implication in On-Farm Water Management
The Kingdom of Saudi Arabia (KSA) is under
extreme water shortage conditions. About 80 % of water in
KSA is utilized by the agricultural sector; therefore, proper
management of irrigation water is required to produce ...
Assessing Agricultural Water Productivity in Desert Farming System of Saudi Arabia
The primary objective of this study was to assess the water productivity (WP) of the annual (wheat, barley, and corn) and biennial (alfalfa and Rhodes grass) crops cultivated under centerpivot irrigation located over desert ...
