No single technical option, whether at macro or at micro level, is in a position to offer economically viable options for all parts of a large country like India. This is because location factors have a dominating influence. Site conditions at certain places may be favorable for construction of only large dams or only small dams or only tube wells in which case the question of choice does not arise. The same argument applies to each of the other alternatives.

Before implementation of any technology a comprehensive analysis of all its impacts, direct as well as indirect, primary as well as secondary, sustainable as well as non-sustainable, favorable and unfavorable should be made. Hence, there should always be a search for area specific optimum mix of technologies and actions.
