Measuring for irrigation efficiency
Improving the efficiency of irrigation water use on farms can reduce input costs, improve the sustained delivery of available water to pastures and enhance the provision of water-related ecosystem services.
In this 2021 case study, water use and irrigation efficiencies were analysed in 15 centre pivot irrigation systems on six mixed (irrigated and dryland) pasture-based dairy farms in the Southern Cape (in the Tsitsikamma and Outeniqua areas), South Africa.
The study uses scientifically researched data on dairy farms to explore pasture and product water use and various irrigation efficiencies on the farm. It advocates for the efficient use of irrigation water on dairy farms and the use of water meters to this end.
