Usage of CC impact assessment

What is it about?

This paper presents a basin-scale approach to irrigation planning for use in areas with scarce hydrological and meteorological data. Past irrigation planning proposals in these areas have not specified the required volumes of water or the necessary capacities of irrigation facilities. Our consideration of irrigation projects in the Pursat River Basin, based on meteorological data inputs estimated by using a general circulation and/or climate change model, showed that our planning method can be applied despite the scarcity of data. Application of the results of long-term climate change modelling by Japan’s Meteorological Research Institute and a distributed water circulation model developed by Institute for Rural Engineering, NARO (NIRE), show that it is possible to model and use basic data when observational data are inadequate.
