Headwaters are fragile environments threatened by anthropogenic actions. The regeneration of headwaters calls for a practical approach through integrated environmental management. This book discusses various issues concerning headwater regions of the world under wide-ranging themes: climate change impacts, vegetal cover, sub-surface hydrology, catchment and streamflow hydrology, pollution, water quality and limnology, remote sensing and GIS, environmental impact assessment and mitigation, socio-economic impacts, public participation, education and management, and integrated watershed management. This book aims to bring about an awareness in sustainable regeneration of headwater regions and particularly highlighting the problems of environmental management in highlands and headwaters. These regions consist of great reserves of natural resources which need to be exploited and managed sustainably.
