Conserve Energy Future. 12 billion to 27 billion annually. Intensive cultivation leads to removal of large quantities of nutrients from the soil which results to in loss of soil fertility. Mining disturbs the physical, chemical and biological features of the soil. Natural basins without outlet for water, low permeability of subsurface horizons, internal drainage, low intake rate of surface soils and obstructions to natural flow of rain water etc. The costs of preventing salinization are incredibly cheaper than the reclamation projects in salinized areas. In many parts of the world, mining activities or rather improper mining activities … 4.2 Causes of land degradation in the Sahel. The Problem Today . Governments, international organizations, and other environmental stakeholders need to ensure there are appropriate measures for making zero net deforestation a reality so as to inhibit soil degradation. About 40% of the world’s agricultural land is severely diminished in quality because of erosion and the use of chemical fertilizers, which prevent the land from regenerating. It affects global climate through alterations in water cycle and energy balances and disruptions of carbon, nitrogen and sulphur cycles. Avoiding deforestation completely is an uphill task. Most of the crop production practices result in the topsoil loss and the damage of soil’s natural composition that makes agriculture possible. The effects of soil erosion go beyond the loss of fertile land. Silting of drainage, canals, rivers and reservoirs results in increased floods and droughts. The causes of land degradation can be divided into natural hazards, direct causes, and underlying causes. In addition to these causes, intensive cultivation using high-yielding short-duration and fertilizer-responsive cultivars of crops has further accelerated the loss of plant nutrients which is much greater than what is supplemented through fertilizers. When trees are removed by logging, infiltration rates become elevated and the soil remains bare and exposed to erosion and the buildup of toxicities. Degradation of Natural Resources | Environment, Biosciences, Engineering and Technology (With Diagram). In the soil erosion, uppermost fertile layer of soil which contains essential nutrients is lost. Disturbances in the hydrologic cycle due to inefficient use of surface irrigation water, poor land development, seepage and poor drainage have resulted in higher water tables. Soil erosion is a serious problem in hills, arid and semi-arid areas. As populations grow, individuals can be sensitized and educated regarding sustainable forest management and reforestation efforts. (And 7 Ways to Reuse), Are Egg Shells Recyclable? Taking land out of production would allow soil carbon to rebuild and become stable. Soil erosion is a continuous process that occurs either slowly or at an alarming rate. Soils are a fundamental natural resource, and are the basis for all terrestrial life. Soil erosion can either be caused by natural forces like wind or water or can be caused by human behavior like deforestation or the building of dams. Plants act as protective covers as they are helpful at making the soil stronger by stabilizing the land surface. Main agents of soil erosion are (1) Water, (2) Wind, (3) Waves and (4) Glaciers Removal of the top layer of soil by various means, which include both natural events and human activities, is called as soil erosion. In the same context, soil degradation may also bring about loss of biodiversity. Altogether, industrial and mining activities degrade the soil’s physical, chemical, and biological properties. With the objective of understanding the distinct nature of soil quality decline, here are the various causes, effects, and solutions of soil degradation. Either way, soil erosion can lead to severe environmental degradation since large areas of land can become useless due to the erosion of soil. As stated earlier, about 40% of the world’s agricultural land is lost on the account of soil quality depreciation caused by agrochemicals and soil erosion.
