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. Salinized soils can be restored by salt level correction reclamation projects and salinity control. Land reclamation encompasses activities centered towards restoring the previous organic matter and soil’s vital minerals. The FAO expert listed solutions for this, such as “localised drip systems and more efficient systems, to also reduce evaporation.” The Orinoco Basin extends across Veneuela and Colombia. Silting of drainage, canals, rivers and reservoirs results in increased floods and droughts. This cost is documented by declining crop productivity, land use intensity, changing cropping patterns, high … Increased runoff from urban areas also causes a huge disturbance to adjacent water sheds by changing the rate and volume of water that flows through them, and impoverishing them with chemically polluted sediment deposits. asphalt and concrete). Human activities such as poor farming practices may also deplete soil nutrients thus diminishing soil fertility. The areal extent of global degraded areas varies depending on the definitions. Soil degradation (physical, biological, chemical) is unfavorable process, resulting in the soil losing its organic matter - humus accumulated earlier, leading towards decrease of soil fertil-ity with 55-65% and therefore reducing its economic value.

These include erosion, deforestation and overgrazing, flooding and water logging, salination, desertification and ill- planned urbanization. In addition, hillside farm fields need full crop cover to help keep the soil in place. • 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 … 6. In other words, soil degradation takes away the soil’s natural capability of holding water thus contributing to more and more cases of flooding. The economic and social significance of a good land management, including soil and its contribution to economic growth and social progress is recognized in paragraph 205 of the Future We Want. Causes of Land Degradation: In addition to pollution, soil and land face several other problems. 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). This may include activities such as the addition of plant residues to degraded soils and improving range management. 4. Other improper cultivation activities such as farming on steep slope and mono-cropping, row-cropping and surface irrigation wear away the natural composition of the soil and its fertility, and prevent soil from regenerating. 1 Natural Resource Institute, Plant Health and Environmental Group, University of Greenwich, Chatham Maritime, Central Avenue Kent UK ME4 4TB. Drought and desertification destroys 12 million hectares a year (an area the size of Greece) and impacts 1.5 billion people – mainly the poor and underprivileged. Soil degradation is defined as a change in the soil health status resulting in a diminished capacity of the ecosystem to provide goods and services for its beneficiaries.Degraded soils have a health status such, that they do not provide the normal goods and services of the particular soil in its ecosystem..

Some major aspects identified as drivers of soil degradation are: Biodiversity decline Induced by soil contamination, erosion, salinisation and sealing; Soil biodiversity reflects the mix of living organisms in the soil. Soil erosion is a major factor for desertification. Bibliography. Most of the soil eroded from the land together with the chemical fertilizers and pesticides utilized in agricultural fields are discharged into waterways and streams. The Orinoco Basin extends across Veneuela and Colombia. Our pick of five possible solutions. With the reduction of deforestation, soil’s ability to naturally regenerate can be restored. Other important but less studied soil degradation processes include loss … Plants act as protective covers as they are helpful at making the soil stronger by stabilizing the land surface. 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. It is comprised of countless species that create a dynamic and complex ecosystem and is among the most precious resources to humans. Soil pollution refers to the contamination of soil with anomalous concentrations of toxic substances. 2. With the objective of understanding the distinct nature of soil quality decline, here are the causes, effects, and solutions of soil degradation. Examples of soil degradation. In extreme cases, soil becomes unfit for cultivation. Use organic manure. • Soil degradation needs to be recognised, alongside climate change, as one of the most pressing problems facing humanity. The Earth's soil is like the skin on a living being. Stay inspired – subscribe to Positive News magazine. Land Degradation and Desertification. As populations grow, individuals can be sensitized and educated regarding sustainable forest management and reforestation efforts. Foremost of all, it denudates the soil’s vegetation cover, compacts soil during construction, and alters the drainage pattern. Generally, the most important factor that determines healthy or good quality soil is organic matter. Timiryazev Academy students may offer a solution. 4. Again, most of the runoff and sediments from urban areas are extremely polluted with oil, fuel, and other chemicals. Organic farmers who add compost and manure to the soil replenish nutrients while reducing flooding risk and capturing carbon. Plant more trees. According to a recent report to the United Nations, almost one-third of the world’s farmable land has disappeared in the last four decades. We can prevent soil degradation in many ways by geo-chemical methods which help to make soil reusable. Deforestation in Paraguay is thought to have been reduced by 65 per cent within two years of the enactment of its 2004 Zero Deforestation Law – though it remains a huge problem in the country. Avoiding deforestation completely is an uphill task. 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. Soil pollution is defined as the concentration of soil by huge amounts of toxic and poisonous substances that contaminate the soil and make it totally unfit for cultivation. This is otherwise known as conservation tillage, which means tillage mechanisms targeted at making very minimal changes to the soil’s natural condition and at the same time improving the soil’s productivity. Tilling, multiple harvests and agrochemicals have boosted yields at the expense of sustainability. For example, exposure to soil containing high concentrations of benzene increases the risk of contracting leukaemia. Land degradation and soil erosion – particularly of agricultural/arable land and fertile topsoil – is a bigger problem than most people know. These problems have caused soil quality decline, crop yield reduction, economic crisis, poverty, unemployment, and rural urban migration. Soil degradation in India is estimated to be occurring on 147 million hectares (Mha) of land, including 94 Mha from water erosion, 16 Mha from acidification, 14 Mha from flooding, 9 Mha from wind erosion, 6 Mha from salinity, and 7 Mha from a combination of factors. Some of the major types include soil erosion, soil contamination, desertification, soil acidification, soil salinity 4. 2 what is soil? One of the simplest but most forgotten methods of land reclamation is planting of vegetation such as trees, crops, and flowers over the affected soils. The complex forms of the fertilizer’s chemicals are also responsible for denaturing essential soil minerals, giving rise to nutrient losses from the soil. Sustainable land use can help to reduce the impacts of agriculture and livestock, preventing soil degradation and erosion and the loss of valuable land to desertification. The project ran from 2013 - 2018. Land Degradation and Desertification. Overburden removal from the mine area results in a very significant loss of rain forest and the rich top soil. It is a serious environmental problem. In the broadest sense, it comprises alterations in the soil’s chemical property that determine nutrient availability. The reduction of soil nutrients because of alkalinity or acidity or water logging are all categorized under the chemical components of soil degradation. As populations grow, individuals can be sensitized and educated regarding sustainable forest management and reforestation efforts. However, deforestation can be cut down and this can create an impressive way of reshaping and restoring forests and vegetation cover. The agricultural fertilizers and pesticides also damage marine and freshwater ecosystems and the limits the domestic uses of the water for the populations that depend on them for survival. Vegetation cover primarily promotes thee binding of the soil together and soil formation, hence when it is removed it considerably affects the capabilities of the soil such as aeration, water holding capacity, and biological activity. 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.
