Since 1950, 65 percent of Africa’s cropland, which millions depend on, has been affected by land degradation by mining, poor farming practices, and illegal logging. Meanwhile, an estimated 375 million young Africans are estimated to …
Mining companies drive economic growth and progress, but can contribute significantly to environmental degradation if their operations are not carefully managed.6–8 The industry itself cannot operate without disturbing land, so it has direct impact on land quality.
Soil degradation simply means the decline in soil quality which comes about due to aspects such as improper land use, agriculture, and pasture, urban or industrial purposes. It involves the decline of the soil’s physical, biological and chemical state.
Land Degradation & Development is an international journal which seeks to promote rational study of the recognition, monitoring, control and rehabilitation of degradation in terrestrial environments. The journal focuses on:
The causes of land degradation can be divided into natural hazards, direct causes, and underlying causes. Natural hazards are the conditions of the physical environment which lead to the existence of a high degradation hazard, for example steep slopes as a hazard for water erosion.
The relationships between mining and land degradation, their potential socioeconomic impacts and extents were quantified and analysed in this study. A case study was conducted in the Upper West, which is an emerging mining region in Ghana. Land cover, socio-economic and monthly rainfall data were ...
Deterioration in the quality of land, its topsoil, vegetation, and/or water resources, caused usually by excessive or inappropriate exploitation.
Land degradation is defined as the temporary or permanent decline in the productive capacity of the land, and the diminution of the productive potential, including its major land uses (e.g., rain-fed arable, irrigation, forests), its farming systems (e.g., smallholder subsistence), and its value as an economic resource.
Since 1950, 65 percent of Africa’s cropland, which millions depend on, has been affected by land degradation by mining, poor farming practices, and illegal logging. Meanwhile, an estimated 375 million young Africans are estimated to enter the job market within the next 15 years.
Mined area and mine spoils are a major source of erosion and land degradation with resultant loss of water resources and .and productivity. Mining from greater depth such as for oil, gas, etc., cause subsidence and accompanied erosion.
The study is set out to examine land degradation due to mining in Gunda area of Biu plateau with emphasis on the landscape. Both primary and secondary data were used.
1 Land Degradation due to Mining in India and its Mitigation Measures Dr H. B. Sahu Department of Mining Engineering National Institute of Technology
Journal of Degraded and Mining Lands Management is managed by the International Research Centre for the Management of Degraded and Mining Lands (IRC-MEDMIND), research collaboration between Brawijaya University, Mataram University, Massey University, and Institute of Geochemistry, Chinese Academy of Sciences-China.
Land degradation is the major consequences of direct interference of human activities in the natural phenomenon. Land degradation means: 1. Loss of natural fertility of soil because of loss of nutrients.
mechanisation, poor mining methods, use of metal detectors all these results in land degradation,” said Mangisi. Government this year ordered all Chrome mining activities along the Shurugwi- Zvishavane Highway to stop due to the destruction that the unplanned …
Land degradation A necessary first step in the sand mining process is the complete removal of vegetation from the area to be mined ( Barry & Marshall, 2002 ). In the early days of heavy mineral sand mining, this vegetation was piled up and burnt.
Environmental impact of mining Jump to ... The reducing or eliminating of environmental degradation is enforced in modern American mining by federal and state ... of land in the United States alone. This reclaimed land has renewed vegetation and wildlife in previous mining lands and can even be used for farming and ranching. Specific ...
The loss of soil quality is another contributing factor to land degradation, through pollution with heavy metals and acid from mines and power stations. Again, the loss of soil productivity is expensive; for example, it costs about R25 million to neutralise the effects of acid rain in Mpumalanga.
A complete, spatially explicit dataset illustrating the 21st century mining footprint for the conterminous United States does not exist. To address this need, we developed a semi-automated procedure to map the country's mining footprint (30-m pixel) and establish a baseline to monitor changes in mine extent over time.
The impact of mining activities on pollution of air, water, land, soil quality, vegetation including forest ecosystems, and on human health and habitation has become a matter of serious concern.
Land degradation is the temporary or permanent lowering of the productive capacity of land (UNEP, 1992b). It thus covers the various forms of soil degradation, adverse human impacts on water resources, deforestation, and lowering of the productive capacity of …

Abstract. This paper identified 37 mining sites in ten gold mining communities of Ijesaland, Nigeria; examined the forms, levels and extent of land degradation resulted from mining activities; analyzed spatial pattern of land use and finally assessed the effects of mining on livelihood of the people.
Land degradation will remain an important global issue for the 21st century because of its adverse impact on agronomic productivity, the environment, and its effect on food security and the quality of life. Productivity impacts of land degradation are due to a decline in land quality on site where ...
Given its diminutive size, Shurugwi can be said to be a town that has seen more land degradation than it can take. From hair-raising unclaimed mining pits, mercury-contaminated water bodies to brazen deforestation, the mining town’s natural ecosystems are seriously under threat.
Land use conflicts are becoming increasingly apparent from local to global scales. Surface gold mining is an extreme source of such a conflict, but mining impacts on local livelihoods often remain unclear.
And despite Mining, agriculture and forestry, resources historically key to Guyana’s economy, contributing to the overall land degradation, particularly in Regions 1, 4, 7, 8, 9 and 10, the Guyana Lands and Surveys Commission (GLSC) estimates that a total of 0.003 per cent of Guyana’s land is degraded.
Causes, Sources, Effects and Solutions of land pollution: Land pollution means degradation or destruction of earth's surface and soil, directly or indirectly as a result of human activities. The degradation of land that could be used constructively in other words is land pollution.
The following is a list of the major causes of land degradation. Whether it is through building homes, the cultivation of crops, humans have always influenced the landscape. The following is a list of the major causes of land degradation. Home; Food For Thought ... the land where mining activities have occurred can remain completely …
The Food and Agriculture Organization estimated that between 1990 and 2005, gold mining activities in Ghana contributed significantly to land degradation and loss of cultivable land, resulting in a massive loss of forest cover (26%) and arable lands (15-20%) at the Tarkwa, Ayanfuri, Dunkwa, Esaase and Bogoso mining areas in Ghana .
