e-Discussion on Sustainable Water Management and Value Chains
The efficient and effective use of water in irrigation systems is of critical importance for sustainable agricultural development and overall economic growth. The key to sustainable water management is balancing supply and demand. Sustaining irrigated agriculture and crop production with limited water supplies thus requires increasing water use efficiency (water consumed by crop/water applied) and optimising the productivity of water (beneficial biomass/unit of water applied).
Several standards for sustainable crop production include indicators of water use efficiency and/or water productivity. Measuring water – efficiency or productivity – however is a challenge. Measuring stations are often absent in irrigation systems and farmers do not regularly record irrigation time or volumes.
HELVETAS Swiss Intercooperation in a consortium with the Better Cotton Initiative (BCI) and the Sustainable Rice Platform (SRP) is implementing a project to increase water efficiency and food production in the key commodity value chains rice and cotton. A factsheet on the WAPRO Project can be found here.
While the standards and indicators developed by the organisations are clear, water use efficiency and water productivity are expected to progressively improve, there is little meaningful guidance on how water efficiency or water productivity have to be measured especially in surface irrigation systems. This is one of the main challenges in our Water Productivity Project and very likely in other similar projects as well. The questions we would thus like to discuss – among others - in this forum are:
In addition, we would be very interested to get links to similar projects to start an experience exchange and a possible cooperation on the issue of sustainable water management, irrigation efficiency and water productivity.
We are looking forward to your contributions!
