Impact of Soil Degradation: The following are the impacts of soil degradation: 1. Biological factors refer to the human and plant activities that tend to reduce the quality of soil. 1. Consequently, actions such as reducing irrigation, planting salt tolerant crops, and improving irrigation efficiency will have high pay offs because the inputs and the labor-demanding aspects associated with reclamation projects are zero. Examples of soil degradation. These chemical factors normally bring forth irreversible loss of soil nutrients and productivity capacity such as the hardening of iron and aluminum rich clay soils into hardpans. Efforts centre around ensuring no bare soil is exposed, with ‘cover crops’ planted directly after harvest. Examples include leaving the previous year’s crop residue on the surface to shield the soil from erosion and avoiding poor tillage methods such as deep plowing. Increased demand for agriculture commodities generates incentives to convert forests and grasslands to farm fields and pastures. Deforestation causes soil degradation on the account of exposing soil minerals by removing trees and crop cover, which support the availability of humus and litter layers on the surface of the soil. Soil Erosion is a common term that is often confused with soil degradation as a whole, but in fact refers only to absolute soil losses in terms of topsoil and nutrients. Tillage against the slope in sloppy land. ... LADA - Land Degradation Assessements in Drylands.

This protective layer is being stripped away, with half of the Earth's topsoil lost in the last 150 years ('Soil Erosion and Degradation'). Avoiding deforestation completely is an uphill task. In soil, the majority of organic matter is composed of an insoluble residue from plants and microorganism exudates – a fluid discharged from cells – and their decaying remains. Bibliography. Deforestation leads to the loss of the land’s value as, once converted into a dry or barren land, it can never be made fertile again. How Long Does CBD Last? The areal extent of global degraded areas varies depending on the definitions. The erosion process is thus accelerated, creating soil degradation as well as water pollution. Abstract. Still, soil organic matter and plant nutrients can be replenished. • Research by the Economics of Land Degradation Initiative in 2015 calculated that soil degradation is costing between $6.3 and 10.6 trillion dollars per year … SOLUTIONS TO REDUCE SOIL POLLUTION. India is losing a huge amount of money from degraded lands (Table 2). Land Degradation and Desertification. Growing different crops each year, so different nutrients are used and to allow periods of rest (fallow periods) so that soil can regain its fertility. Soil Degradation Research Paper papers for a college level and more complicated tasks for advanced courses. The decline in soil quality as a result of agricultural chemical fertilizers also further leads to water and land pollution thereby lowering the land’s worth on earth.

For example, exposure to soil containing high concentrations of benzene increases the risk of contracting leukaemia. 2. Many people do conceive the idea of Soil degradation but a good number lacks the knowledge of its precise definition. Land is commonly altered from its natural landscape when it rids its physical composition from soil degradation. Soil and land degradation are interrelated issues and often come up in the same context. Soil degradation takes place through many physical, chemical, and biological processes. Drought and aridity are problems highly influenced and amplified by soil degradation. 2002. These elements contribute to a significant amount of soil quality depreciation annually.

This cost is documented by declining crop productivity, land use intensity, changing cropping patterns, high … 1991). Just like the old adage states that “prevention is better than cure,” so does the same concept apply in solving the worldwide problem of soil degradation through salinization. The rates of soil erosion and the loss of soil nutrients as well as the top soil are highly contributed by overgrazing. Land Degradation and Its Causes Proper soil management is a ba-sis for society’s long term social and economic development. It involves the decline of the soil’s physical, biological and chemical state. This also leads to loss of biodiversity, degradation of the soil, and alteration in the ecosystem. Without plant and tree cover, erosion happens much more easily. The Earth's soil is like the skin on a living being. The biological factors affect mainly lessens the microbial activity of the soil. The complex forms of the fertilizer’s chemicals are also responsible for denaturing essential soil minerals, giving rise to nutrient losses from the soil. Soil erosion appears to be the most widespread process of soil degradation and is also the most studied. All these physical factors produces different types of soil erosion (mainly water and wind erosion) and soil detachment actions, and their resultant physical forces eventually changes the composition and structure of the soil by wearing away the soil’s top layer as well as organic matter. However, deforestation can be cut down and this can create an impressive way of reshaping and restoring forests and vegetation cover. Project news & events Related Project. Overburden removal is normally done by the process of blasting or using excavators, which results in generation of large volume of waste (soil, debris and other material).
