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."
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 ...
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, [36] where world annual deforestation is estimated as 13.7 million hectares (34 × 10 ^ 6 ...
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]
As per the Millennium Ecosystem Assessment of 2005, land degradation is in defined as "the reduction or loss of the biological or economic productivity of drylands". [6] A similar definition states that land degradation is the "degradation, impoverishment and long-term loss of ecosystem services".
The proximate causes were clustered into broad categories of agricultural expansion (96%), infrastructure expansion (72%), and wood extraction (67%). Therefore, according to this study, forest conversion to agriculture is the main land use change responsible for tropical deforestation.
With 17 percent of world population, India contributed some 5 percent of human-sourced carbon dioxide emission; compared to China's 24 percent share. On per capita basis, India emitted about 1.4 tons of carbon dioxide per person, in comparison to the United States’ 17 tons per person, and a world average of 5.3 tons per person.
The cultivation of semi-arid regions encourages erosion of soil and is one of the causes of increased desertification. Desert farming is possible with the aid of irrigation, and the Imperial Valley in California provides an example of how previously barren land can be made productive by the import of water from an outside source.
