This chapter evaluates the potentials of, and pitfalls in, rainwater harvesting and groundwater recharging in water-scarce regions of India. It analyses macro and micro level hydrological and geo-hydrological data including rainfall magnitudes and variability, and runoff. The findings suggest that rainwater harvesting and groundwater recharging projects have an extremely limited potential in water-scarce regions of India from the point of view of basin level hydrological impacts and economic viability. This chapter describes the case study of the Narmada River Basin to illustrate the relative importance of blue and green water in managing basin water economies.

Keywords: rainwater harvesting; groundwater recharging; water-scarce regions of India; rainfall magnitudes; rainfall variability; runoff; hydrological impacts; economic viability; Narmada River Basin
