ABSTRACT
The most well-known irrigation systems began as the Triangle and Hippo Estates in the southern Sabi-Lundi Valley, which derive their water from Kyle Reservoir on the Mtilikwe River tributary of the Sabi River. Many other smaller systems have been developed and are planned under government and private development programmes. Increased severity of drought in Southern Africa will make rapid development of the proposed schemes a necessity (Chandiwana et al., 1988; Chandiwana and Snellen, 1994).
