Summary:

Rapid economic development and population growth have resulted in modifications to land-use and land-management and are seriously affecting the availability of water resources throughout India. Urbanization, deforestation, agricultural intensification, shifts between irrigated agriculture and rain-fed crops, and the proliferation of small-scale surface water storage interventions, such as farm-level bunds and check-dams all have contributed to significant changes in the hydrology of catchments and effected the flow regimes of the region’s rivers. The impact of such changes and interventions on local hydrological processes - on streamflow, groundwater recharge and evapotranspiration - have yet to be fully explored, and our understanding of how these changes cumulatively affect water availability at the broader basin-scale, is very limited. The project sought to address the key scientific challenge of representing local, small-scale influences at larger scales. Focussing on the large inter-state Cauvery River basin, and using observations from established experimental catchments in both rural and urban settings, the project explored how changes in land-use, land-cover, irrigation practices and small-scale water management interventions locally affect hydrological processes.  For more on the impacts of the project click here
