Abstract
In this chapter, the authors summarizes the complex considerations involved in assessing the real water saving from adoption of MI technologies, and thereby highlighting the challenges in assessing the real potential of MI technologies in India. It summarizes the issues emerging from the analysis presented in the previous chapters in terms of areas for future research. Particularly, the need to quantify crop water requirement for various horticultural crops, and the need to understand the economic viability of using solar pumps for micro irrigation systems are highlighted. Given the limits to expanding the area under micro irrigation systems in India, the authors also argue that there is a need to focus on other water saving technologies in agriculture, in terms of understanding the benefits and impacts.

Penman-Monteith equation can be used for estimating ET. The empirical relationship established by Siddique et al. (1989) can be used for arriving at cumulative bare soil evaporation from estimated ET and leaf area index. Then the actual soil evaporation can then be estimated from the values of bare soil evaporation using light extinction coefficient.
