Intervention In Catchment Land use to Protect A Tropical Lake Ecology & Its Water Storage Capacity
Catchment of any lake has always been of great importance while considering its environmental management for its sustenance both in terms of its quality as well as quantity. The present study was under taken on a typical tropical urban lake which is also source of drinking water for population of a capital city. Agriculture is the dominant land use of the basin and has created potential ecological problem to this lake, its storage capacity is depleting at considerable rate and the nutrients with surface runoff is the causes of eutrophication of the lake, agrochemicals used pose potential danger to water quality, which is a serious concern for human health. A change is land use to urban development on limited basis has been seen as a solution that will address the problem of soil erosion and siltation apart from input of agrochemicals joining the lake.
