It looked unreal then! It appeared a little relevant afterwards. Centuries later it made sense. And only in the recent times has the intensity and appropriateness of Leonardo Da Vinci's observation that water is the driver of nature, struck us! 

The heat evaporates the moisture in the soil rapidly leading to widespread drought conditions. The changes in ocean temperatures are modifying the ocean currents, thus creating erratic and extreme weather conditions - creating more intense and frequent storms and cyclones; thus creating cycles of floods and drought.

As part of the research study, River Basins and River Basin Organisations in South Asia, done by the Society for Participatory Development Hyderabad, CapNet South Asia (Read More) and Gomukh Environmental Trust for Sustainable Development Pune (Click Here), data about individual river basins has been collected for the river basins in South Asia.

This report presents the findings of a study done by Pravah on the concurrent monitoring of the world's largest drinking water pipeline project, the Narmada project, which is supposed to cover 9633 villages an 131 towns of Saurashtra, Kutch and parts of North Gujarat.

This case study presents a erosion response model for watershed prioritisation in Bajaj sagar sub catchment of Mahi basin. The natural hydrologic processes like erosion of soil, movement of soil and its deposition in various parts of reservoir are very crucial phenomena occurring in any watershed. Erosion of soil is a very complex process which is affected by many factors and the loss caused is irreversible.

Micro-watershed level planning requires a host of inter-related information to be generated and studied in relation to each other. Remotely sensed data provides valuable and up-to-date spatial information on natural resources and physical terrain parameters.

Water flows without regard to political and administrative boundaries. Water planning with respect to rivers should therefore be done for the river basin (or sub-basin) as a whole. River basin planning also has to look in an integrated way at all the relevant parameters like urban and rural populations, water usage patterns, water pollution, wastewater flows.
