Challenges with eradicating illegal mining in Ghana: A

Although the efforts of large-scale mining companies to implement alternative livelihood projects have drawn praise from the Ghana Chamber of Mines and donor bodies, a recent study by Hilson and Banchirigah (2008) argues that these activities have done little to address the illegal mining problem.The mining industry is a significant asset to the development of countries. Ghana, Africa’s second-largest gold producer, has benefited from gold mining as the sector generates about 90% of the country’s total exports. Just like all industries, mining is associated with benefits and risks to indigenes and the host environment. Small-scale An Integrated Approach to Assess the Environmental Impacts of Large

Ghana, like most resource-rich countries, is saddled and inundated with resource curse challenges. Key among them is the problem of illegal small-scale gold mining activities (ISSGMAs), which is mercilessly robbing the nation of its ecological integrity, despite attempts by successive governments to remedy the situation. In the midst of this The mining sector in Ghana consists of both small-scale and large-scale mining, each of which has varying environmental impacts.

ENVIRONMENTAL IMPACT ASSESSMENT: INSIGHTS

According to Aryee et al. (2003), problems associated with mining, especially small-scale mining in Ghana for example, can be quite substantial. This is because, illegal mining by virtue of their clandestine nature are not amenable to monitoring. These activities are, therefore, responsible for a substantial share of the environ-In Ghana, the endemic nature of Buruli ulcer in communities adjacent to mining activities suggests that proximity to artisanal and small-scale gold mining (ASGM) is a risk factor for this disease, as is the case of the higher prevalence of Buruli ulcer in the Amansie West District.26 An increased risk of infection was not associated with directReview of Environmental and Health Impacts of Mining in Ghana

The local socioeconomic effects of gold mining: Evidence from Ghana

In Ghana, inappropriate regulations and the promotion of foreign investment in large-scale mining projects at the expense of the welfare of rural communities have made securing a small-scale mining licence very difficult. One potential solution to this problem is to pressure multinationals to relinquish unused portions of their concessions.We set up a mortality surveillance system around two of the largest gold mines in Tanzania between February 2019 and February 2020 to estimate the mortality impact of gold mines. Death circumstances were collected using a standardized verbal autopsy tool, and causes of death were assigned using the InSilicoVA algorithm.
