Remote sensed imagery in combination with secondary agricultural statistic was used to map crop water productivity (WP) in the Nile River Basin. Land productivity and crop tandardized gross value production (SGVP) were calculated at administrative level using the agricultural census data. Actual evapotranspiration (Eta) generated from remote sensing was used to assess crops consumptive water use. WP was then calculated by dividing SGVP by Eta in the cropped areas. Results show land productivity has a huge variation across the basin.

The WOCAT-LADA-DESIRE mapping tool is based on the original WOCAT mapping questionnaire (WOCAT, 2007). It has been expanded to pay more attention to issues such as biological and water degradation, it also places more emphasis on direct and socio-economic causes of these phenomena, including their impacts on ecosystem services. It evaluates what type of land degradation is actually happening where and why and what is being done about it in terms of sustainable land management (SLM) in the form of a questionnaire.
