Case Studies of Innovative Irrigation Management Techniques

Abstract

Irrigation is a vital input in the agricultural productivity and agricultural growth. More than 80% of available water resources worldwide as well as in India are being presently utilized for irrigation purposes. However, in India, the average water use efficiency of Irrigation Projects is assessed to be only of the order of 30-35%. There is no doubt that modernization of irrigation system like concrete lining to the inner surface of the open channel; canal automation etc. will save water significantly. But these techniques require huge capital investment, hence uneasy to adopt. On this background it is appropriate to know the innovative, simple, low cost, easy to adopt, water conveyance techniques used in the command of few irrigation projects in Maharashtra. The paper discusses the need to increase the Water Use Efficiencies of existing Irrigation Projects and new projects and the success case studies in detail. The findings show that such pioneering techniques shall be implemented in the command areas of other irrigation projects as and where found techno economically feasible to achieve improvement in crop yield and good water management with high water use efficiency.
