This book by Space Applications Centre (SAC), Indian Space Research Organisation (ISRO) is an outcome of the project on National Wetland Inventory and Assessment (NWIA) . Increasing concern about how our wetlands are being influenced had led to formulation of the project entitled to create an updated database of the wetlands of India.

Wetlands defined as areas of land that are either temporarily or permanently covered by water exhibit enormous diversity according to their genesis, geographical location, water regime and chemistry. They are one of the most productive ecosystems and play crucial role in hydrological cycle. Utility-wise, wetlands directly and indirectly support millions of people in providing services such as storm and flood control, clean water supply, food, fiber and raw materials, scenic beauty, educational and recreational benefits. Thus, their identification and protection becomes very important.

The study on “Snow and Glacier Studies”  was taken up by the Space Applications Centre, Indian Space Research Organisation (ISRO) and executed in collaboration with fourteen research organizations and academic institutions of the country, at the behest of the Ministry of Environment and Forests.

 Himalayan mountains contain important natural resources of frozen fresh water in the form of snow and glaciers. These glaciers are unique as they are located in tropics, high altitude regions, predominantly valley type and many are covered with debris.

The great northern plains of India sustain on the perennial melt of snow and glaciers meeting the water requirements of agriculture, industries, domestic sector even in the months of summer when large tracts of the country go dry. Therefore, it is important to monitor and assess the state of snow and glaciers and to know the sustainability of glaciers in view of changing global scenarios of climate and water security of the nation. Any information pertaining to Himalayan glaciers is normally difficult to be obtained by conventional means due to its harsh weather and rugged terrains.
