Conjunctive use of surface and groundwater for small-scale irrigation in Zimbabwe


, : Conjunctive use of surface and groundwater for small-scale irrigation in Zimbabwe. Groundwater drought, pollution and management Proceedings International Conference, Brighton, UK, 1-3 February 1994: 145-153

Surface water in Zimbabwe is unreliable and poorly distributed. Over half the country is occupied by intrusive granites which supply sufficient water only for drinking and stock in villages. Collector wells were used to enhance the yields of boreholes in the crystalline basement. Alluvial aquifers occur in dry parts of the country and can be used for irrigation of large areas as they supply considerably higher yields.

Because the significance of the term prairie soils has by extension become ambiguous, the new term 'brunigra' soils is proposed for those originally designated as prairie soils, and diagnostic features are given.
