Standards and guidelines for improved efficiency of irrigation water use from dam wall release to root zone application: Guidelines
Expanded Title:The activities undertaken during the course of the project have contributed to local knowledge on issues regarding irrigation water use efficiency. The outcomes have created new knowledge in that: • Efficiency refers to the state of a water balance for a defined spatial and temporal area rather than to the value of a performance indicator; and • Improved efficiency is achieved through a process of assessment and targeted actions, rather than general practices. The resulting approach that has been documented in the final report therefore still complies with the original proposed improvement process of “measure; assess; improve; evaluate”. It promotes an investigative approach to improving efficiency, rather than relying only on water accounting. The main output of the project was the compilation of guidelines for improved irrigation water management from dam wall release to root zone application. The guidelines are aimed at assisting both water users and authorities to achieve a better understanding of how irrigation water management can be improved, thereby building human capacity, allowing targeted investments to be made with fewer social and environmental costs. Using lessons learnt during the WRC project, best practices and technologies were introduced and illustrated.
