The specialized book "Spatial System Innovations in Watershed Management" offers a comprehensive examination of the development of a methodological framework that facilitates the identification of suitable areas for the implementation of innovative systems to enhance rain-fed agriculture in the Doddahalla watershed. This area is one of the most drought-affected regions in Karnataka, India. The authors, Syed Ashfaq Ahmed and K. Ibrahim-Bathis, focus on biophysical factors that influence the suitability for planning innovations in water management. By applying a spatial multi-criteria evaluation of various thematic layers, such as land use, precipitation, runoff, and crop water requirements, ideal locations for rainwater harvesting and suitable cultivation practices are identified. The sustainable application of these methods aims to increase food production and reduce water scarcity, contributing to more sustainable agriculture.
