Suitability for rain-fed Wheat (intermediate inputs)

The raster dataset of suitability for rainfed wheat with intermediate inputs has a spatial resolution of 5 * 5 arc minutes and is in geographic projection. Information with regard to wheat suitability was obtained from the "Derived Soil Properties" of the FAO-UNESCO Soil Map of the World which contains raster information on soil properties.

Purpose

This database will be used mainly for poverty and food insecurity mapping, particularly for analysing where the people live at global scales in relation to:

- Agroecological zones

- Marginal or productive lands

- Major foodcrop production systems, in particular those important to food security for the rural poor.

Supplemental Information

Each crop has a set of requirements as to the biophysical environment it prefers and would yield best. These requirements in terms of LGP, Thermal climate, dormancy, soil fertility, soil physical characteristics and toxic elements for wheat have been compared with actual conditions as given by the Soil Map of the World and GAEZ and a suitability rating was arrived at.

The dataset is available for download (below) in both ASCII and ESRI GRID formats. A layer (.lyr) and legend (.avl) file are provided in the downloads.
