Deforestation in India is the widespread destruction of major forests in India. It is mainly caused by environmental degradation by farmers, ranches, loggers and plantation corporations. In 2009, India ranked 10th worldwide in the amount of forest loss , [ 1 ] where world annual deforestation is estimated as 13.7 million hectares (34 × 10 ^ 6 ...
Historic desertification is the study of the desert-forming process from a historic perspective. It was presumed in the past that the main causes of desertification lay in overuse of the land resulting in impoverishment of the soil, reduced vegetation cover, increased risk of drought and the resulting wind erosion. However recent projects to ...
Desertification is a gradual process of increased soil aridity.Desertification has been defined in the text of the United Nations Convention to Combat Desertification (UNCCD) as "land degradation in arid, semi-arid and dry sub-humid regions resulting from various factors, including climatic variations and human activities."
The institute has a wide collection of books and journals in its library named after Dr. P.C. Raheja. The library uses bar coding of books. The Environment Information System (ENVIS) centre on desertification is also part of institute. All the Regional Research Stations are linked with Consortium for e-resources in Agriculture (CeRA) by static ID.
Tropical forest in El Salvador expanded more than 20% between 1992 and 2001. Based on these trends, one study projects that global forestation will increase by 10%—an area the size of India—by 2050. [54] 36% of globally planted forest area is in East Asia – around 950,000 square kilometers. From those 87% are in China. [55]
India and the United States cooperated in 2001, using Landsat MSS with a spatial resolution of 80 meters, to get accurate forest distribution data. India thereafter switched to digital images and advanced satellites with 23 meters resolution and software processing of images to get more refined data on forest quantity and forest quality.

However, India was the third largest emitter of total carbon dioxide in 2009 at 1.65 Gt per year, after China (6.9 Gt per year) and the United States (5.2 Gt per year). With 17 percent of world population, India contributed some 5 percent of human-sourced carbon dioxide emission; compared to China's 24 percent share. [35] [36]
