Brochure, flyer, fact-sheetReal water savings in agricultural systems 2023
Also available in:
No results found.This course targets field-level programme officers and technical advisors in the water, food, irrigation and agricultural sectors. In the context of the global water shortages and challenges for water savings in agricultural systems, this course introduces interventions and tools, and more specifically the real water savings in agricultural systems (REWAS) project, that aims to provide practical guidance on the implementation of real water savings. -
Policy briefReal water savings in agriculture 2023
Also available in:
No results found.Irrigated agriculture consumes the largest share of water for human use by far, signifying that it is within the irrigation sector that solutions to address and manage water scarcity must be found. Unfortunately, overcoming the water crisis through agricultural interventions is not simple, and increasing attention is now being paid to common misconceptions and overly simplistic (and often erroneous) views in agricultural water management. In particular, the role that ‘increasing water use efficiency’ can play in tackling the water crisis is dominated by misunderstandings related to hydrology, economics, and human behaviour. This policy brief is based on extensive work carried out by FAO and FutureWater under the Asia Pacific Water Scarcity Programme (WSP). It clearly explains the complexities associated with efforts to increase water use efficiency and the importance of utilising water accounting and consistent use of terminology in developing water management interventions. A practical new tool is introduced that provides clear and practical guidelines on how to mplement ‘real’ water savings in agriculture by selecting suitable interventions that enhance crop water productivity. -
Book (stand-alone)Does improved irrigation technology save water?
A review of the evidence
2017Also available in:
No results found.The Near East and North Africa (NENA) Region has the lowest per-capita fresh water resource availability among all Regions of the world, consuming more than 85 percent of renewable fresh water resources through irrigation. Demography, food security policies, overall socio-economic development and climate change will accelerate the fast-widening gap between availability and demand for fresh water resources in the coming decades. How can NENA countries simultaneously reduce this gap, promote sustainable water resources management and contribute effectively to food security? Several measures are put in place. However, modernising irrigation systems remains dominant through typically converting the ‘low-efficient’ surface methods into the ‘high-efficient’ drip methods. The often underlying assumption is that increasing irrigation efficiency will allow to ‘save’ substantial amount of water that could be released for environment or other uses. The evidence from research and field measurements shows that this is not the case. While the benefit at local “on-farm” scale may be dramatic, at basin scale total water consumption by irrigation tends to increase significantly.
