Rainwater Harvesting In South Asia: Education and Finance

Rainwater is a major source of irrigation in many parts of Pakistan, India, Sri Lanka, Nepal, Bangladesh, Bhutan and the Maldives. About 60-70 percent of total cropped area is irrigated by watercourses and canals. Only about 30 percent of the area depends on rainfall. Since none of these countries channels rainwater into an integrated system, most of the rainwater mixes into the drainage effluent and is wasted. In some parts of India, rainwater is stored in water tanks for irrigation of crops, but due to non-availability of sufficient educational facilities and financial constraints, the practice of harvesting rainwater is very low in this region.

Rainwater in the big cities goes to waste and no consideration is given to save this precious source of irrigation and drinking. In most of the areas, the drainage channels are covered but inlets are provided to add up the rainwater into drainable effluents. By maintaining separate small channels/drains to drain out and bring rainwater to a center place for storage and keeping it unmixed with drainable effluent, it can be optimally utilized for justified purposes. This objective can be achieved by educating people of the methods and ways to conserve rainwater and store it for future use.

The financing of such activities is also a point of consideration. In fact, a substantial amount is required to implement the idea of having two separate channels: one for drainable effluents and the other for rainwater conservation. The financing can be made partially through self-sponsorship (about 70 percent of the total cost by the beneficiaries) and international and national/regional donor agencies (the rest 30 percent). Some of the works can be carried out by the beneficiaries by providing services instead of spending money over there.
