Water Erosion is a widespread form of degradation that occurs in all agroclimatic zones of India.\n<ul class=\"wp-block-list\">\n<li>It can occur through splash, sheet, rill, and gully erosion.<\/li>\n\n\n\n<li>Soil erosion starts with the raindrops falling onto the bare soil surface.<\/li>\n\n\n\n<li>The impact of raindrops breaks up surface soil aggregates and splashes particles into the air.<\/li>\n\n\n\n<li>On sloping land, detached soil material flows with runoff down the slope, resulting in soil loss. An area of about 126 Mha has been suffering from various degrees of water erosion.<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Wind Erosion<\/strong> &#8211; This type of erosion basically involves displacements of soil particles by wind.\n<ul class=\"wp-block-list\">\n<li>Usually, the soil is removed in thin layers as sheet erosion, but the wind&#8217;s effect can sometimes carve out hollows and other features.<\/li>\n\n\n\n<li>Wind erosion is a function of wind velocity, soil characteristics, and land use.<\/li>\n\n\n\n<li>Land degradation due to wind erosion is limited to the arid regions of India. An area of 11 Mha suffers from wind erosion of various intensities.<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Acidic Soil<\/strong> &#8211; Acidic soil develops in humid areas due to excessive leaching of cations with high rainfall.\n<ul class=\"wp-block-list\">\n<li>This results in a lower pH and loss of soil fertility. Chemical amendments like lime can reclaim soil.<\/li>\n\n\n\n<li>About 6.98 Mha are affected by acidic soils, which is about 9.4% of the soils classified into saline, sodic, and saline-sodic.<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Salt-affected soils<\/strong> &#8211; These soils contain excessive soluble salts, exchangeable sodium, or both, affecting crop yield and production.\n<ul class=\"wp-block-list\">\n<li>Depending upon the physiochemical properties and the nature of the salt, the soils are classified into saline, sodic, and saline-sodic.<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Flood, Drought and Other Climatological Extremes<\/strong> &#8211; Flood, drought and other climatological extremes are common in many parts of the country.\n<ul class=\"wp-block-list\">\n<li>These natural disasters cause widespread land degradation, heavy monetary losses, and a serious setback to a country&#8217;s economic development.<\/li>\n\n\n\n<li>It has been estimated that eight major river valleys spread over a 40 Mha area of the county, covering 260 million people.<\/li>\n\n\n\n<li>Besides environmental degradation, poverty and marginalisation are the other significant factors.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading has-text-color has-link-color wp-elements-cd4495ef09a879c10ec578682cd1b722\" style=\"color:#015aa7\"><span class=\"ez-toc-section\" id=\"Impact_of_Land_Degradation\"><\/span><strong>Impact of Land Degradation<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Consequences of land degradation can be seen as follows:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Decline in Agricultural Productivity<\/strong> &#8211;
