Rating Systems to Evaluate Onfarm Water Conservation

by John D. Hedlund, USDA Soil Conservation Service, Portland, OR, USA,
Paul K. Koluvek, USDA Soil Conservation Service, Portland, OR, USA,



Document Type: Proceeding Paper

Part of: Development and Management Aspects of Irrigation and Drainage Systems

Abstract:

The U. S. Department of Agriculture, Soil Conservation Service, concentrates its assistance on modernization of onfarm irrigation systems and improvement of water management to provide more efficient use of the finite water supplies in the West. The planning process includes screening onfarm irrigation projects so SCS can put its limited planning dollars and people where they will protect the long-term productivity of the soil and water resource base. A worksheet has been developed to evaluate water conservation potential of irrigation projects based on physical, economic, environmental, social, legal, and institutional considerations. In addition, a Farm Irrigation Rating Index (FIRI) has been developed to consistently assess onfarm irrigation water use for the present situation and for improved systems.
