Some of these salts are transported in solution by rivers.<\/li><li>In areas with a low water table, salts may percolate into the subsoil, and in well-drained regions, they are carried away by flowing water.\u00a0<\/li><li>However, poor drainage can lead to the stagnation of water with high salt concentration, causing the deposition of salts in the topsoil upon evaporation.<\/li><li>In regions with a high sub-soil water table, injurious salts may be drawn up from below through capillary action during the dry season&#8217;s evaporation.<\/li><li>Canal irrigated areas, where excessive water is often applied, contribute to the rise of the groundwater level.\u00a0<\/li><li>This, in turn, leads to the appearance of saline and alkaline efflorescences on the soil surface, primarily composed of sodium, calcium, and magnesium salts, facilitated by capillary action.\u00a0<\/li><li>Vast areas in states like Uttar Pradesh, Punjab, Haryana, arid regions of Rajasthan, and semi-arid areas of Maharashtra, Gujarat, Andhra Pradesh, Telangana, and Karnataka face challenges associated with salinity and alkalinity due to over-irrigation.<\/li><li>While projects like the Indira Gandhi canal in Rajasthan have transformed sandy deserts into productive granaries, they have also given rise to significant problems related to salinity and alkalinity in these areas.<\/li><li>Balancing irrigation practices and implementing effective drainage systems are crucial for managing and mitigating the adverse impacts of salt accumulation in the soil.<\/li><\/ul>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"DESERTIFICATION\"><\/span><strong>DESERTIFICATION<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<ul class=\"wp-block-list\"><li>Desertification refers to the expansion of desert-like conditions in arid or semi-arid areas, resulting from both human activities and climatic changes.\u00a0<\/li><li>A significant portion of the arid and semi-arid region situated between the Indus and the Aravalli range is experiencing the encroachment of desert conditions.<\/li><li>Wind erosion plays a pivotal role in desert soils, causing substantial soil loss.\u00a0<\/li><li>The sand transported by the wind settles on adjacent fertile lands, diminishing their fertility.\u00a0<\/li><li>Gradually, these once fertile lands begin to blend with the advancing desert, exacerbating the desertification process.\u00a0<\/li><li>Alarming estimates suggest that the Thar Desert is advancing at a rate of approximately 0.5 km per year.<\/li><li>The process of desertification can be attributed to various factors, including uncontrolled grazing, indiscriminate deforestation, and the expanding human population.\u00a0<\/li><li>Additionally, climate change has played a role in fostering the spread of deserts, contributing to the challenging conditions faced by these arid and semi-arid regions.\u00a0<\/li><li>The combined impact of these factors poses a significant threat to the ecological balance and sustainability of the affected areas.\u00a0<\/li><li>Addressing desertification requires coordinated efforts in sustainable land management, conservation, and mitigating the adverse effects of climate change.<\/li><\/ul>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"WATER_LOGGING\"><\/span><strong>WATER LOGGING<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<ul class=\"wp-block-list\"><li>The formation of flat surfaces and depressions contributes to the issue of waterlogging, where soils become saturated with water either from rainfall or leakage from various water sources.\u00a0<\/li><li>In India, the extent of waterlogged soils is substantial, covering about 12 million hectares, with half located along the coast and the other half inland.
