Silicon Valley's Integrated Water System

California's Santa Clara Valley, widely known as the Silicon Valley, manages its water resources admirably, integrating surface water, groundwater, artifi cial recharge, waste-water treatment, imported water, water conservation and public participation. As India seriously tackles its water challenges, the Silicon Valley's case history provides insights into how citizens of a hydrological basin may take control of their indigenous water resources based on an understanding of the essential attributes of hydrological systems, and drawing upon the best available science to achieve sustainable management. This case history also highlights the fact that even with the most sophisticated integrated water management, there are defi nite limits to the extent to which indigenous resources can satisfy water demands.

A Framework for India's Water Policy

India's annually renewable water resources are finite, subject to uncertain climatic variability. These resources have to be systematically monitored and managed to meet the legitimate needs of a diverse society. Ideally, a unifying national water policy to enable rational water management will give consideration to scientific knowledge of the nature of the resource within the set of human values to which India's democracy is committed.

Groundwater Management and Ownership

The conclusions of the recent report of the Planning Commission's expert group on groundwater management and ownership, from an earth-science perspective, are poorly informed and simplistic. The report is conspicuous in its failure to seek counsel from the nation's scientific, professional and public institutions that have expertise and interest in a wise utilisation of groundwater resources.
