Any Irrigation system invariably contributes to enhanced crop production and increased farm incomes to the rural households and it provides cyclical development in different sectors of the economy as a whole. However, some of the factors impede the agricultural output despite substantial contribution by the irrigation systems and they include (i) economic factors like adequate farm returns; (ii) performance factors namely water use efficiencies; (iii) social factors like failure to achieve equitable distribution of water and environmental factors related to soil salinity, water logging, public health, etc. In such a situation it is imperative to evaluate the performance of the irrigation systems against its desired objectives based on the FAO & IWMI, New Delhi guidelines and such evaluation of the irrigation systems provide a crucial feed back to improve the water management to make the systems more accountable besides providing vital inputs to the planners, policy makers, implementing agencies and the beneficiaries to initiate feasible corrective measures. To improve the performance of the existing age old irrigation systems & its efficiency, the baseline survey, has been carried out in the selected irrigation schemes comprising major, medium and minor irrigation schemes by considering the year 1998-99 as the base year for conducting such a study to arrive identified performance indicators to serve as bench marks for future comparison on completion of the ongoing project. The Rajolibanda Diversion Scheme, Mahaboob Nagar dist, A.P is one of the selected major irrigation scheme commands and the baseline survey is carried out in RDS Main Canal and its distributaries, etc. and an attempt is made to evaluate the performance of the RDS project using performance indicators like engineering indicators, operational indicators, agricultural indicators ,environmental and socio economic indicators as per the guide lines of IWMI,New Delhi & FAO on the equity , timeliness, adequacy, location, uniformity and irrigation efficiency criteria, Socio, economical environmental aspects and the results are discussed in the present paper.
