Foreword Deutsche Gesellschaft für InternationaleZusammenarbeit (GIZ) GmbHA 2/18, Safdarjung Enclave,New Delhi 110029 Rajeev AhalDirector Natural Resources Managementand Agroecology Message Water is intrinsic not only to life but also to economic growth and development.The honourable PrimeMinister of India has highlighted the need for comprehensive and integrated Water Vision@2047, includingadaption and mitigation strategies with timelines. He has emphasised on the need for water budgeting andmanagement (both supply and demand sides) at gram panchayat and village as well as town/city level to betaken up universally with people’s participation and under leadership of rural and urban local bodies. In ruralareas agriculture uses 80-90% of water, therefore appropriate cropping patterns, crop varieties, efficient waterutilization need to be promoted with a ‘whole of Government’ approach. The Green and Sustainable Development Partnership (GSDP), signed at the highest levels in May 2022between India and Germany, aims at aligning bilateral, triangular, and multilateral cooperation on climatepolicy and SDG implementation, particularly focusing on the 2030 Agenda and the Paris Agreement.In thespirit of GSDP, the Indo-German Bilateral Project “Water Security and Climate Adaptation in Rural India(WASCA)” implemented by GIZ in partnership with Ministry of Rural Development and Ministry of JalShakti, Government of India, has been instrumental in piloting innovative approaches, strengthening capacitydevelopment measures and facilitating knowledge exchange. Water budgeting is crucial for India’s sustainable development, especially in water stressed areas, whereresource scarcity and uneven distribution threatens economic stability, food security and climate resilience.Proactive water management needs to shift towards a data-driven approach that systematically accounts forinflows, outflows, and water availability and access. The Jalagam web-based water budgeting application,developed in partnership with NITI Aayog, is instrumental in identifying contextual measures for bridging thegap between water demand and supply, identifying hotspots of consumption, and enabling efficient resourceallocation. It’s piloting across 18 blocks has demonstrated that a structured water management approachenhances water security, resilience, and sustainability. Its national level uptake will strengthen informeddecision-making, ensuring equitable access and robust planning in the face of climate change and growing andcompeting water demands, ultimately safeguarding India’s water future. I congratulate NITI Aayog and Indo-German Bilateral Project “Water Security and Climate Adaptation in RuralIndia (WASCA)” project team for successful piloting and documenting the joint efforts in this report. I wish tothank all the primary stakeholders for providing relevant inputs and contributions to this pilot assessment andhelping finalise this report for wider dissemination for contributing to India’s Water Vison @2047.
