Water is an important and integral part of our ecological system. It is not only a vital source of life for human beings but it also supports agriculture, livestock, industries, and the environment. Declining per capita water availability, competing water demand for different uses and users, changing food habits and life styles, livelihoods and socioeconomic scenarios climate change and environmental needs call for holistic management of water resources. The planning, designing, development and management of water resources depend on its spatial and temporal variation.
While doing so it is also important to consider natural, social, physical, financial and human capital as well as cultural, historical and geographical situations available in the country. Integrated Water Resources Management (IWRM) is basically a process of utilization of water resources in such a manner so that combined and coordinated resources utilization creates many times better cumulative impact both in terms of quality and quantity without adverse impact on other resources, than single resource utilization and combining the impact of all the water resources afterwards. It varies from place to place and no single solution fitting to all the situations can be developed.
