Climate change in the form of temperature increase and rainfall variability has intensified in the last three decades. Rainwater harvesting is one of the mitigation strategies in drought-prone regions. Hence, studies on rainwater harvesting technologies were conducted in four villages of Tumkur, Gadag, Belagavi and Chikkaballapura districts during 2011 to 2018 as a part of National Innovations in Climate Resilient Agriculture (NICRA). During 2017, 77,700 m3 and 6,410 m3 of water was harvested in farm ponds and water harvesting structures, respectively. The harvested water was used for supplemental irrigation during drought periods to increase and stabilize crop production and improve the system's productivity. After desilting of community pond the water storage capacity has increased by 2-3 times and also there was an increased cropping intensity of the village. Plastic lining materials had shown efficacy in minimizing seepage and percolation losses. In-situ moisture through trench cum bund conserved the harvested rainwater during June-August which has increased the surrounding soil moisture content and kept the moisture for a longer duration. This increased the yield of the groundnut by 20.59 per cent which was not possible without trench cum bunding. The ground water level in open wells and borewells started improving by diverting runoff water into defunct / less yielding borewells. [ABSTRACT FROM AUTHOR] |
