EVALUATION OF AN IRRIGATION WATER MANAGEMENT SCHEME - A CASE-STUDY

The Integrated Water Management Scheme, which was in operation in the command area of the Paladugu major distributary in the Nagarjunasagar Right Canal Command Area in Andhra Pradesh, India since 1980, was eval uated. This was done in terms of water supply-requirement ratio and ot her indices such as irrigation intensity, crop productivity and croppi ng pattern. A comparison with the performance of the system in the yea r before the scheme was introduced revealed that the scheme effectivel y led to a sustained increase in the irrigated area and irrigation int ensity (by >25%) resulting in increased crop production. Yields of pad dy and cotton went up by more than 100%. (C) 1997 Elsevier Science B.V .
