Abstract
The present study was taken up in the black clay soil zone of Manthani mandal of Peddapalli district Telangana state in which series of on farm water harvesting structures were taken up by small and marginal farmers. The sizes of water harvesting structures, season wise cropping pattern, crop yields, cost of cultivation and net margins were collected from randomly selected farmers.
Thereafter, techno economic feasibility of taking up water harvesting structures was assessed. The field study revealed that these structures are technically feasible and financially viable for effective rainwater harvesting, providing critical irrigation to crops, enhancing crop yields and cropping intensity, resulting in resilience to adverse effects of climate change and consequent improvement in livelihood security of farmers.
Keywords: Techno economic feasibility, water harvesting structure, livelihood security
