This book provides a framework to characterize river basins based on water availability, water supplies, water uses and water demands to ascertain the need and measures available for improving crop water productivity that would be effective at various scales, i.e., plant-level, plot-level, irrigation system level and basin level. This is an essential reference for anyone interested in water management and agriculture.
- Presents clear explanations of the physical and technical measures that can be adopted to improve productivity of water in agricultural production under different basin conditions
- Offers physical strategies for improving water productivity in agriculture in different agroecological regions, along with the institutional and policy measures that affect them
- Includes methodologies for assessing the food security challenges of individual nations using empirical analysis and global datasets
Academics working on drought management challenges and policy responses, policy makers, Agriculturalists, Climatologists. Upper-year undergraduate courses and graduate courses that either focus or touch on Indigenous environmental governance
