Planning a group trip to the closest or local farms who are growing crops using any bad chemicals or mistreating the soil in any other way. Get Positive News stories in your inbox each week. A guide to the soil degradation. Increased demand for agriculture commodities generates incentives to convert forests and grasslands to farm fields and pastures. ADVERTISEMENTS: In this article we will discuss about the causes and control of land degradation. Soil degradation has been defined as a process that leads to decline in the fertility or future productive capacity of soil as a result of human activity (United Nations Environment Programme, 1993). 4. 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). Soil loses its natural vitality and balance of elements, degrading its quality and lending it barren and … This can be accomplished by intercropping, which means … Home. 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. Overgrazing destroys surface crop cover and breaks down soil particles, increasing the rates of soil erosion. 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. As an example, mining destroys crop cover and releases a myriad of toxic chemicals such as mercury into the soil thereby poisoning it and rendering it unproductive for any other purpose. The rates of soil erosion and the loss of soil nutrients as well as the top soil are highly contributed by overgrazing. Soil Degradation The river's delta is covered with tropical rain forest. We use cookies to ensure that we give you the best experience on our website. The word ‘organic’ here describes the molecules of carbon that bond together, often containing hydrogen, oxygen and nitrogen. Poor land management, such as deforestation , overgrazing, construction activities and forest fires are among the main causes of this situation. The erosion process is thus accelerated, creating soil degradation as well as water pollution. Efforts centre around ensuring no bare soil is exposed, with ‘cover crops’ planted directly after harvest. Hence, there is a necessity for individuals all over the world t… 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. 2. Land and soil are very important resources to our future because of how they allow us to produce food and other resources (amongst other things). Simple steps and innovative thinking will help improve the quality of soil in the country Land degradation is any kind of alternation in the overall condition of the soil which decreases its actual productive capabilities. Experts suggest rotating pastured land used by the meat and dairy industries so less is being used at once. India is losing a huge amount of money from degraded lands (Table 2). How Long Does CBD Last? These problems have caused soil quality decline, crop yield reduction, economic crisis, poverty, unemployment, and rural urban migration. For this reason, the transformed land is unable to soak up water, making flooding more frequent. 4. The reduction of soil nutrients because of alkalinity or acidity or water logging are all categorized under the chemical components of soil degradation. RECARE was a multidisciplinary research project of 27 different organisations that assessed the threats to Europe's soils and identified innovative solutions to prevent further soil degradation. 1. Proper tillage mechanisms hold as one of the most sustainable ways of avoiding soil quality decline. 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. Title: Soil Degradation 1 Soil Degradation. 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. Land Degradation and Desertification. Still, soil organic matter and plant nutrients can be replenished. Again, most of the runoff and sediments from urban areas are extremely polluted with oil, fuel, and other chemicals. It's a protective layer that keeps all other parts together.

Soil degradation is a complex problem that requires governments, institutions, communities and individuals to take joint measures. This is indeed the most visible effect of soil degradation, but does not cover all of its aspects. Use minimum tillage. Land degradation occurs when the economic and biological productivity of land is lost, primarily through human activities Our pick of five possible solutions. While Soil degradation occurs naturally, it has been highly exuberated by anthropogenic activities. These protect the soil while returning nutrients and plant matter too. There are certain agricultural practices that are environmentally unsustainable and at the same time, they are the single biggest contributor to the worldwide increase in soil quality decline. There are several physical factors contributing to soil degradation distinguished by the manners in which they change the natural composition and structure of the soil. The Earth's soil is like the skin on a living being. 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. As populations grow, individuals can be sensitized and educated regarding sustainable forest management and reforestation efforts. This protective layer is being stripped away, with half of the Earth's topsoil lost in the last 150 years ('Soil Erosion and Degradation'). 1 Natural Resource Institute, Plant Health and Environmental Group, University of Greenwich, Chatham Maritime, Central Avenue Kent UK ME4 4TB. Plant more trees. 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. Land reclamation encompasses activities centered towards restoring the previous organic matter and soil’s vital minerals. These protect the soil while returning nutrients and plant matter too. Find Other Styles Note that from the first issue of 2016, MDPI journals use article numbers instead of page numbers. This also leads to loss of biodiversity, degradation of the soil, and alteration in the ecosystem. While soil degradation may occur naturally, it has been highly exuberated by anthropogenic activities. 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.. Home‎ > ‎ Solutions: What Can We Do? Soil degradation has become a serious problem in both rainfed and irrigated areas of India. Therefore, the misuse or excessive use of fertilizers increases the rate of soil degradation by destroying the soil’s biological activity and builds up of toxicities through incorrect fertilizer use. Causes of Land Degradation: In addition to pollution, soil and land face several other problems. Some of the major types include soil erosion, soil contamination, desertification, soil acidification, soil salinity 4. 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- As populations grow, individuals can be sensitized and educated regarding sustainable forest management and reforestation efforts. 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. The picture of wind erosion from the Dust Bowl era (figure 5.12) provides a graphic illustration of land degradation. It is mainly caused by salt buildup and leaching of nutrients which corrupt the quality of soil by creating undesirable changes in the essential soil chemical ingredients. Sustainable forest management efforts and reforestation schemes are key. Soil degradation is the decline in soil condition caused by its improper use or poor management, usually for agricultural, industrial or urban purposes. Also, preserving the integrity of guarded areas can significantly reduce demonstration. Overburden removal from the mine area results in a very significant loss of rain forest and the rich top soil. Year after year, huge acres of land lost due to soil erosion, contamination and pollution. Wind erosion can occur when soil is dry and loose, the surface is bare and smooth, and the landscape has few physical barriers to wind. Destruction of Infrastructure Minimum use of chemicals in farming. 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. the soil degradation process estimated over the past five to 10 years and the kind of physical human intervention that was causing soil degradation (Oldeman et al. Hence, the contributing factors to soil quality decline such as overgrazing, poor tillage methods, and deforestation are also the leading causes of desertification characterized by droughts and arid conditions. The soil quality decline is exuberated more and more as a result of the mechanization of agriculture that gives room for deep plowing, reduction of plant cover, and the formation of the hardpan. As stated earlier, about 40% of the world’s agricultural land is lost on the account of soil quality depreciation caused by agro-chemicals and soil erosion. Soil degradation examples include decline in soil fertility, adverse changes in alkalinity, acidity or salinity, extreme flooding, use of toxic soil pollutants, erosion, and deterioration of the soil’s structural condition. However, deforestation can be cut down and this can create an impressive way of reshaping and restoring forests and vegetation cover. 1: 68. There are several physical factors contributing to soil degradation distinguished by the manners in which they change the natural composition and structure of the soil. In extreme cases, soil becomes unfit for cultivation. Tilling, multiple harvests and agrochemicals have boosted yields at the expense of sustainability. Because soil degradation contributes to land degradation, it also means that it creates a significant loss of arable land. Biological factors refer to the human and plant activities that tend to reduce the quality of soil. 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. Examples of soil degradation. Some bacteria and fungi overgrowth in an area can highly impact the microbial activity of the soil through bio-chemical reactions, which reduces crop yield and the suitability of soil productivity capacity. Soil degradation? asphalt and concrete). S. Usman1. To restore the lost soil mineral matter and organic content, it would require what is known as land reclamation. Soil erosion appears to be the most widespread process of soil degradation and is also the most studied. To understand the distinct nature of soil quality decline, below are the causes, effects, and solutions of Soil degradation. The Orinoco Basin extends across Veneuela and Colombia. The river's delta is covered with tropical rain forest. Land degradation and soil erosion – particularly of agricultural/arable land and fertile topsoil – is a bigger problem than most people know. The FAO expert listed solutions for this, such as “localised drip systems and more efficient systems, to also reduce evaporation.” Home. The transition to … Altogether, industrial and mining activities degrade the soil’s physical, chemical and biological properties. 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. On the same context, soil degradation may also bring about loss of biodiversity. Terracing and Contour Ploughing By ploughing with the contours (shape) of the land rather than against it you reduce water erosion, also the need to irrigate … The costs of preventing salinization are incredibly cheaper than the reclamation projects in salinized areas. Urbanization has major implications on the soil degradation process. As a result, soil quality and agricultural productivity is greatly affected. 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. The post Causes, Effects and Solutions of Soil Degradation appeared first on Conserve-Energy-Future. This may include activities such as the addition of plant residues to degraded soils and improving range management. Use Soil-friendly Agricultural Practices. In other words, soil degradation takes away the soil’s natural capability of holding water thus contributing to more and more cases of flooding. Soil erosion, fertility decline, lowering of soil pH (dystrification), increase of soil nutrients in soil (eutrophication), soil salinity, waterlogging and soil pollution are identified as the important processes among them. Terraced farming needs to be implemented to make hillside agriculture manageable. What are the consequences of soil degradation? Avoiding deforestation completely is an uphill task. With time, the sedimentation process can clog waterways, resulting in water scarcity. Cultivate pulse crops. 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. These elements contribute to a significant amount of soil quality depreciation annually. Without plant and tree cover, erosion happens much more easily. In the long-term, the physical forces and weathering processes lead to the decline in soil fertility and adverse changes in the soil’s composition/structure. Possible solutions to soil degradation. Widespread soil degradation, leading to a decline in the ability of soil to carry out its ecosystem services, is caused largely by non‐sustainable uses of the land. SOLUTIONS TO REDUCE SOIL POLLUTION. While soil degradation may occur naturally, it has been highly exuberated by anthropogenic activities. The Natural Resources Conservation Service estimates the world is losing 75 billion tons of soil a year annually. 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.
