Methodology of integrated watershed management for sustainable water resources use

摘要

Water resources in the Asia region are very severe and scarce, and a very rapid population increase is apparent in recent years. This rapid population increase causes not only increase of water demand but also affect the land use change, resulting land degradation, soil erosion and change in hydrologic regimes. To overcome those water crises, it is necessary to develop a methodology and analytical methods for the desired watershed management. In the paper, the author proposed an integrated watershed management as one of the desired watershed managements for the next generation and showed a framework and a research flow of the management emphasizing the capacity building and the water governance as well as scientific researches on water resources issues.
