Map of rainfed areas in 2017
IWMI’s global irrigated and rainfed area maps (GIAM and GMRCA, Biradar et al., 2009, Thenkabail et al., 2009) have ben merge with released irrigated area maps accessible online; http://waterdata.iwmi.org/applications/irri_area/to ...
Crop yield of rainfed areas in 2008
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 ...
Agricultural water productivity for rainfed areas in 2008
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 ...
ICARDA Efforts to Promote In Situ/On-farm Conservation of Dryland Agrobiodiversity
Dryland biodiversity has only recently got due attention because of its potential to contribute in overcoming the effects of global challenges caused by land degradation and and climate change (FAO, 1989). More particularly, ...
Actual Evapotranspiration of irrigated areas in 2006
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) ...

Changes in barley (Hordeum vulgare L. subsp. vulgare) genetic diversity and structure in Jordan over a period of 31 years
In many regions of the world, the cultivation of landraces is still common, in particular in centres of crop diversity. Significant effort has been put into ex situ conservation of landraces but limited data exist on the ...

Role of geoinformatics in ensuing global food security with special reference to dryland agroecosystems
Agriculture plays an important role in providing
food security in developing countries. Better agricultural
information is one of the key factors in understanding current
trends and status that determine food security from ...
