Soil degradation is a complex problem that requires governments, institutions, communities and individuals to take joint measures. Home. With the reduction of deforestation, soil’s ability to naturally regenerate can be restored. Degradation leads to reduction in crop yield in the affected lands and a possible decline in cropping intensity. Organic molecules are the building blocks of life. 2002. Soil loses its natural vitality and balance of elements, degrading its quality and lending it barren and … It was also reported that all of … PLAY. Rainfall, surface runoff, floods, wind erosion, tillage, and mass movements result in the loss of fertile top spoil thereby declining soil quality.All these physical factors produces different types of soil erosion (mainly water and wind erosion) and soil … Avoiding soil degradation is crucial to our well-being. It is comprised of countless species that create a dynamic and complex ecosystem and is among the most precious resources to humans. Or as it i… Causes of Land Degradation: In addition to pollution, soil and land face several other problems. 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. How Long Does CBD Last? This may include activities such as the addition of plant residues to degraded soils and improving range management. 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. Home. These protect the soil while returning nutrients and plant matter too. 4. Tillage against the slope in sloppy land. Get updates delivered right to your inbox! Title: Soil Degradation 1 Soil Degradation. Avoiding soil degradation is crucial to our well-being. Organic farmers who add compost and manure to the soil replenish nutrients while reducing flooding risk and capturing carbon. What Solutions Exist to Prevent Soil Erosion? 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. Soil / land management practices such as tillage and cropping practices, directly affect the overall soil erosion problem and solutions on a farm. In the broadest sense, it comprises alterations in the soil’s chemical property that determine nutrient availability. The biological factors affect mainly lessens the microbial activity of the soil. Countour farming in hill regions. 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. The health of soil is a primary concern to farmers and the global community whose livelihoods depend on well managed agriculture that starts with the dirt beneath our feet. S. Usman1. With the objective of understanding the distinct nature of soil quality decline, here are the causes, effects, and solutions of soil degradation. 05 Jun 2017 News item. 3. For two consecutive days, 4-5 December 2017, FAO and the Russian State Agricultural University - Timiryazev Agricultural Academy held … 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. Bibliography. Preventing salanization in the first place is thus an environmentally friendly means of offering solution to soil degradation. Simple steps and innovative thinking will help improve the quality of soil in the country Drought and aridity are problems highly influenced and amplified by soil degradation. Farmer’s perception of land degradation and solutions to restoring soil fertility in Niger. Sitemap. 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. This also leads to loss of biodiversity, degradation of the soil, and alteration in the ecosystem. In warm climates, they also preserve moisture. 1. {4.1.6, 4.2.1, 4.7} 3 Land degradation is a driver of climate change through emission of greenhouse gases and These problems have caused soil quality decline, crop yield reduction, economic crisis, poverty, unemployment, and rural urban migration. In addition, hillside farm fields need full crop cover to help keep the soil in place. The outcomes of soil erosion and quality decline are widely irreversible. Some of the major types include soil erosion, soil contamination, desertification, soil acidification, soil salinity 4. For this reason, the transformed land is unable to soak up water, making flooding more frequent. 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. Avoiding deforestation completely is an uphill task. 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. 3. 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. 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. Also, preserving the integrity of guarded areas can significantly reduce demonstration. Stay inspired – subscribe to Positive News magazine. 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. The Natural Resources Conservation Service estimates the world is losing 75 billion tons of soil a year annually. Land degradation is one of the great challenges of the 21st century. Solutions 1. 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. Use minimum tillage. Besides, climate change combined with human activities continues to worsen soil degradation. 1. Solutions we have come up with where informing Farmers and warn them about our topic "Soil Degradation and Agriculture." Solutions need to be developed and introduced which address both issues simultaneously. It's a protective layer that keeps all other parts together. When trees are removed by logging, infiltration rates become elevated and the soil remains bare and exposed to erosion and the buildup of toxicities. STUDY. Soil degradation is a complex problem that requires governments, institutions, communities and individuals to … What are the consequences of soil degradation? ADVERTISEMENTS: In this article we will discuss about the causes and control of land degradation. 1991). Soil degradation? These organisms interact with one another and with plants and small animals forming a web of biological activity. However, deforestation can be cut down and this can create an impressive way of reshaping and restoring forests and vegetation cover.
