Abstract
In this chapter, the authors raise several questions related to adoption of MI systems in India vis-à-vis the sections of the farming community, which adopts the technology and the sections which do not adopt. The authors also raise several questions relating to the methodology adopted currently for analyzing the physical, agronomic and economic benefits from MI, and assessing the future potential of MI systems’ in terms of saving water from agriculture and making more water available for environment, in the wake of the wider recognition of the distinction between ‘notional water saving’ and ‘real water saving’ from efficient irrigation technologies. It also deals with the issue of positive/negative externalities and real ‘social benefits’ and costs associated with the use of MI systems, a major justification for provision of heavy capital subsidies for its purchase by the farmers.
