New WRC reports (September 2008)

Abstract

WRC reports Report No: TT 267/08 Technology Transfer and Integrated Implementation of Water Management Models in Commercial Farming (A Pott; N Benadé; PS van Heerden; B Grové; JG Annandale and M Steyn) Commercial irrigation accounts for about 62% of South Africa’s total water use. There have been increased calls for the irrigation sector to improve its water use efficiency, and through the years the WRC has funded various research projects to achieve just that. These projects have resulted in the development of several irrigation efficiency models and programs, including the Agricultural Catchment Research Unit (ACRU) model, Water Administration System (WAS), irrigation scheduling program (SAPWAT), Soil Water Balance (SWB) and Risk Management Simulation Model (RISKMAN), which have all have proved to be popular and are used widely. A new technology transfer project involved water user associations and water boards to act as centres of excellence as a means of lesson sharing. A central feature of this project is to capture accurate data in a geographic information system (GIS).
