Irrigation: Local mapping

Remote sensing techniques have been employed by the International Water Management Institute (IWMI) to accurately investigate the status of irrigation in South Africa. By focusing on specific regions, this technology provides reliable mapping data on the scale of irrigation carried out by smallholder farmers at the local level. Discrepancies currently lie in data available to national governments on the areas being supplied by irrigation water. However, a recent working paper by IWMI states that by replicating this local mapping approach across Africa such inconsistencies would be overcome. This is essential for identifying and addressing the key flaws in irrigation systems, including areas where water supply is no longer sufficient during the extended dry season.
