It is now recognized that irrigated agriculture is producing more than just food products. Irrigated fields are part of agroecosystems that perform many different functions that are of use to humans. However, irrigated agriculture may as well produce negative impacts on the ecosystems as they depend upon increased pollution, depletion of water resources elsewhere, ultimately rendering dis-services to other categories of the population. Assessing the values of nonmarketed ecosystem services and disservices supplied by agriculture is an important policy challenge for promoting an irrigated agriculture that provides the right balance of food products and other environmental services. This short review shows there are still many challenges both for measuring demand for various ecosystem services, and integrating demand functions into a coherent policy framework.
