How to Evaluate Rural Development Schemes

In 2000-01, almost Rs 10,000 crore was spent on rural development schemes. The central government has almost a dozen major schemes in operation. But how is the success or failure of these schemes to be evaluated? By the quantum of funds allocated? By the fulfillment of targets?Or do we need a social cost-benefit analysis for each scheme? Rural development schemes may be sponsored by either the centre or state governments, or both. While the central government spent Rs 6,760 crore in 2000-2001, additional state government spending differs from state to state. State governments declare their own schemes, or contribute more resources towards central government schemes.
