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.

This chapter is an initial exploration and sharing of experiences and ideas based largely on a case study of a group of small farmers who have occupied and are producing on land that they believe they have an historical right to. The group, called Mahlahluvani – although they include people from other communities and claimant groups – are part of a land claim that has been lodged on the land they now occupy, but the claim is not yet settled.
