This systematic review explores the application of geospatial technologies, including remote sensing (RS) and Geographic Information Systems (GIS), in agricultural water management in India. The study analyzed 60 research articles published between 2010 and 2022, following PRISMA guidelines. The review highlights the use of RS and GIS for addressing agricultural water management challenges, such as evapotranspiration (ET) estimation, irrigation water requirement, drought assessment, runoff estimation, water body mapping, groundwater recharge, and soil moisture estimation. The study reveals that while Landsat data is widely used, more advanced technologies like Sentinel, UAVs, and hyperspectral sensors have not been fully explored for water resource assessment. The integration of RS and GIS provides cost-effective and efficient solutions for monitoring and managing water resources, enabling precise irrigation scheduling, drought monitoring, and water conservation. The review emphasizes the importance of geospatial technologies in sustainable agricultural practices, particularly in the context of climate change and increasing water scarcity. The findings suggest that further research is needed to explore advanced Earth-observation technologies for improved water resource management in India. The study concludes that geospatial technologies play a crucial role in enhancing agricultural productivity and ensuring sustainable water use in the face of growing population and environmental challenges.This systematic review explores the application of geospatial technologies, including remote sensing (RS) and Geographic Information Systems (GIS), in agricultural water management in India.
