International Conference on Reimagining Rainfed Agro-ecosystems: Challenges & Opportunities during 22-24, December 2022 at ICAR-CRIDA, Hyderabad T1-07R-1062 Enhancing Climate Resilient Agriculture in Semi-Arid Region through Group Micro Irrigation by Collectivization and Equitable Sharing of Groundwater: Case Study in Maharashtra and Telangana, India Arun Bhagat*, Upasana Koli, Jyothirmayee Kandula and Marcella Dsouza WOTR Centre for Resilience Studies (W-CReS), Watershed Organisation Trust (WOTR), Pune (India) *arun.bhagat@wotr.org.in Groundwater is one of the primary sources of irrigation for food production in many countries of the world, and India, which significantly contributes to the food supply for countries, is the most groundwater-dependent country on earth. Despite their importance, the resources are heading for a crisis in many regions, mainly due to their enormous exploitation to increase production to feed the growing population. Climate change, it is anticipated, will pose an additional significant threat to groundwater resources in the future (Shahid et al., 2017), and has affected agricultural practices to the extent that farmers have increased the use of synthetic fertilizers and agrochemicals to protect themselves from the damages. Therefore, looking at the challenging water scenario, the government has been stressing about increasing the efficient use of water. However, despite the numerous schemes, technological inputs, and new methods of productivity enhancement, it has scarcely addressed the water problem in its entirety. To address these issues and challenges, Watershed Organisation Trust (WOTR) undertook an action research project - the Group Micro Irrigation (GMI) approach, devised to enhance agriculture productivity for a group of smallholder farmers with special attention to efficient water use. Methodology Water is considered a common good rather than privately owned in this approach. This viewpoint is to help manage scarce water resources judiciously and equitably. The GMI approach comprises four main components: groundwater management on the supply and demand side, promotion of CRA practices, facilitation of market linkages, and integration of applied research by providing small methods or tools to support farmers. In the first component of GMI, measures such as harvesting rainwater and construction of soil and water conservation structures to recharge groundwater are taken to support the supply side. And to support the demand side, accumulating private groundwater resources and distributing water through a common-drip-irrigation system are the measures taken. The second component of promoting Climate Resilient Agriculture (CRA) as a package of practices is a measure undertaken to boost soil health and plant resilience to ensure a harvest in the face of weather and environmental challenges. The third component involves encouraging market linkage through Farmer Resilience through land and water management interventions, water management and governance 29 | Page

And the fourth component is about integrating applied research to support farmers using simple tools and methods includes maintaining field books by farmers, crop water budgeting, and assessing groundwater availability by testing well water depth and pump discharge. The study was focused on the water scare area of Maharashtra and Telangana states. The GMI model details are given here under.

Impact of GMI intervention on cropped and irrigated area, cropping intensity, and crop and water productivity Assessment indicator Average rise in the cropped area (%) 40.01 Average rise in Irrigated area (%) 99.20 Average rise in cropping intensity (%) 67.42 Average rise in crop Productivity (%) 82.86 Average rise in water productivity (%) 77.81 Average change in cropping pattern Comparison between Pre and Post-intervention Shifted from grain crops to high-valued crops e.g. vegetable RULES (BY GROUPS) FOR THE MANAGEMENT OF THE GMI Water budgeting and crop planning before every season. The selection of crops should be the same for all or with the same harvesting duration based on the water budget decisions Compulsory use of micro-irrigation systems and water-intensive crops are not allowed when water availability is limited Follow climate-resilient agricultural practices A compulsory contribution of group funds based on GMI land area for maintenance and repair expenditures 30 | Page Resilience through land and water management interventions, water management and governance
