the mining sector of liberia: current practices and

After the discovery of high-grade iron ore in Bomi Hills, Bong, and Nimba, natural resources have been the basis of Liberian economy and its people livelihood. Iron ore mining was the mainstay of the Liberian economy between 1960 and 1980, contributing more than 60% of export earnings and about 25% of GDP (Boakye et al. 2012), which then ranked Liberia as the largest exporter of iron in Africa and third largest in the world. Gold and diamond mining in Liberia was carried out largely by alluvial mining of small-scale operations, with estimates of over 100,000 artisanal miners in Liberia. But nearly 14 years of war (1989–2003) destroyed much of the country’s productive infrastructure and brought mining to a virtual halt. Liberia is estimated to hold reserves ranging from between two to five billion metric tons of iron ore and three million ounces of gold (Boakye et al. 2012). The major mineral commodities produced in Liberia are iron ore, gold, and diamond. Mining concessions cover an operational area of 113,256 ha (Ministry of Finance 2013). Besides the production of iron ore, gold, and diamond, Liberia remains largely unexplored and has shown other minerals such as beryl, tin, columbite-tantalite, phosphates, zinc, copper, lead, rare earth minerals, nickel, molybdenum, beach sand (zircon, rutile, ilmenite, and monazite), bauxite, kyanite, chromite, uranium, and silica sands. All are characteristically associated with Precambrian/Proterozoic rocks which underlie most of the country

Since the cessation of hostilities, revival of the mining industry has been an explicit government objective in its efforts to reconstruct the country and to underpin growth by leveraging Liberia’s rich natural resources to the extent of attracting massive foreign investment of USD 7.6 billion and creating about 10,000 jobs (LEITI 2016; Ministry of Finance 2013). Investments comprise, among others, rehabilitation of old and installation of new mining plants, construction of railways, roads, and bridges. As a result, the Government of Liberia has enacted (2003–2006) a legal framework providing for the sustainable use and conservation of natural resources. However, the adoption of the environmental management tools such as Environmental Impact Assessment (EIA), Environmental Impact Statement (EIS), and the harnessing of best practices valorizing local knowledge are still lacking. Thus, the pressure on the environment is still heavy

Industrial mining in Liberia includes gold and iron ore. The mining of these minerals is associated with huge environmental impacts ranging from land form degradation, pollution of air quality, loss of biodiversity, and watercourse contamination. The latter is of serious challenge in the mining sector because of the climatic condition of Liberia. For instance, the rehabilitated Nimba mine is estimated to generate 150 million tonnes of waste rocks (60 Mm3 of waste rocks) over its first 20 years mine’s life (AcerlorMittal Liberia Limited 2013). In addition, the New Liberty Gold mining operations require 1.2 Mm3 of water annually and its tailings storage facility (TSF) is expected to discharge 9.4 Mm3 (received from rainfall and runoff during the wet season) of water annually into surface water streams (Aureus Mining 2014). Therefore, there are greatest potential impacts on water quality, human health, and ecosystem from these activities coupled with increased sediment load due to the high erosion potential of soil when disturbed and effluents discharged of toxic substances, such as cyanides and heavy metals including acid mine drainage (AMD) that can cause long-term impairment to watercourses and biodiversity (Akcil and Koldas 2006). Additionally, the data collection for environmental information has been decentralized among various line ministries and agencies, as well as international organizations and institutions which have a stake in the Liberian environment

Based on the current development trend, the objective of this paper is to carry out a systematic review of the current water use-related challenges in the Liberian mining sector particularly the water management issues and mining regulatory frameworks. Results from the review will be used to recommend policy strategies that promote sustainable water resources management in the mining sector. Accordingly, “Historic and economic perspectives of the Liberian mining sector” of this paper discusses the historical and economic contribution to the economy. “Mineral legislation, regulatory framework, and environmental challenges in the Liberian mining sector” describes the current mining methods, legislative frameworks, and environmental challenges while “Policy suggestions” presents a case study and water resource management challenges. “Conclusion” presents policy suggestions and concludes with some recommendations

Liberia is a leading country in mineral resources with substantial iron ore, gold, and diamond deposits. Iron ore mining was previously undertaken by American and European companies in the areas of Bomi Hills, Bong Mines, Mano River, and Nimba. Those concessions resulted in widespread clearance of tropical rainforest for mines (open-cast pits), processing plants, housing and roads, railways, and unmanaged deposit sites. The Nimba mine for instance produced some 300 million tons of mining wastes (unwanted materials) that were deposited in the surrounding forest. Environmental impact assessments had not been conducted at the sites and potential risks were unknown
