1.1.2.WATER USE Total water withdrawal was estimated at 4.2km3 in 2002. Agriculture is the greatest water user in Zimbabwe accounting for 79 per cent of total water use. Agricultural water uses are for irrigation, fish farming and livestock watering. Irrigated agriculture will continue to dominate the water demands for Zimbabwe in the foreseeable future.
1.2.WATER QUALITY, ECOSYSTEMS AND HUMAN HEALTH Surface water in Zimbabwe is usually of good quality for irrigation: generally conductivity is less than 500 microsiemens/cm. Groundwater on the other hand tends to be more variable in quality, with some being saline, sodic or saline-sodic. Current knowledge about the quality of groundwater in the country is limited. Chemical analyses of water are done before the implementation of drip systems but are rarely done for surface and sprinkler systems. Poor drainage and salinity are not a major problem in irrigated areas in Zimbabwe, although they have been observed in some schemes under surface irrigation; this is normally associated with poor land levelling and poor water management or the use of poor quality irrigation water. There is a general increase in the use of agrochemicals in the country due to the intensification of crop production. It is thought that the regular use of commercial levels of agrochemicals is an occupational risk for irrigation farmers and increases the risk of contamination of both surface water and groundwater resources. However, data on water analysis showing agrochemicals levels in natural water sources in Zimbabwe are not obtainable and it is thus difficult to establish the extent of pollution due to irrigated agriculture. In Zimbabwe the net effect on human health of irrigation development tends to be positive. There is an improvement in the nutritional status of the people both on the scheme and in the surrounding area. Indirectly, benefits are twofold: -because of the economic progress resulting from irrigation, communities can afford better health care; -the upgraded infrastructure (roads, electricity, etc.) that accompanies irrigation ensures better basic health services such as child immunization, family planning and mother and child health. However, despite the net positive effect on human health, irrigation (especially surface irrigation) in the country is associated with an increased risk of malaria, schistosomiasis, enteric diseases like diarrhoea, agrochemical poisoning, and skin and eye diseases.
