Sustainability

Sea level rise and decrease are ancient phenomena related to the geologic glacial/interglacial cycles. But since the 19th century and the industrial revolution, an acceleration of sea level rise has been observed through tide gauge measurements and satellite altimetry.

This CGWB map provides us with block level information about groundwater exploitation across the country. Blocks are categorized as safe, semi-critical, critical, over exploited and saline based on the usage.

As observed by the United Nations Environment Program (GRID-Arendal) ice and snow are major components of the climate system. That is why human induced climate change can be first observed in Polar Regions where most of Earth's snow and ice are concentrated. In these areas global warming induces the progressive melting of ice and snow.

Altered frequencies and intensities of extreme weather, together with sea level rise, are expected to have mostly adverse effects on natural and human systems.

The earth is currently warming rapidly. And this warming is bringing about massive changes. Our glaciers are melting rapidly. The artic ice-shelf is breaking apart into pieces and threatens to modify the salinity of the oceans.

A number of films on climate change are available on the Centre for Science and Environment (CSE) store. These include:

This hindi document from the rainwater harvesting site of the Centre for Science and Envir

This document from the Department of Drinking Water Supply (Government of Kerala) published in the Extraordinary Gazette No. 92/2004, dated 12-01-2004 by the Government of Kerala includes a notification on the amendment of rules and includes:

The document informs that traditionally Indians worshipped both water and rain as “Jala” and “Varuna”. Even rivers were worshipped. Till 3000 B.C., RWH happened without human effort as rain got collected in rivers and natural depressions. Civilizations flourished on river banks all over the world Indus valley civilization in India.
