Adaptation and end-user communication
South Asia is expected to be seriously affected by the impacts of climate change since most economies are relying on agriculture and natural resources like water. The region already faces water stresses due to increase in population growth, urbanization, and increasing demands in the agriculture, industrial and hydropower sectors. Climate change is expected to further aggravate water shortage.
This project aims to represent and quantify (with uncertainty) the major hydrological variables (e.g. streamflow, surface runoff, groundwater level) for the entire Indian region (defined here as the drainage areas with runoff contribution to India).
The methodology is based on a participatory model development process, which combines existing numerical methods with local, regional and national expert knowledge to create an adapted modelling tool. This tool can be used for studying the effects of potential climatic changes (primarily using the CORDEX SA projections) and related adaptation strategies, for water resources management, and for operational hydrological warning services in the country.
The objectives of the project are:
• Calculation of extreme climate indices for the precipitation and temperature;
• Development of the bias-corrected scenarios for the selected general circulation model (using the DBS tool);
• Assessment of the impact of climate change on water resource availability using the HYPE hydrological model;
