Abstract
Artisanal gold mining occurs informally and therefore relies on low technologies and extraction methods lacking pollution controls. As a result, despite the fact that artisanal gold mining produces only twenty percent of the world’s gold, it releases more mercury than any other sector and represents the largest source of mercury emissions. At various points during the gold mining process, mercury is released and emitted into the atmosphere during various points in the gold mining process, where it deposits into soil, lakes, and rivers. This framework document provides a pragmatic approach for designing representative studies and developing uniform sampling guidelines to support estimates of morbidity that are explicitly linked to exposure to land-based contaminants from small-scale artisanal gold mining activities. A primary goal is to support environmental burden of disease evaluations, which attempt to attribute health outcomes to specific sources of pollution. The guidelines provide recommendations on the most appropriate and cost-effective sampling and analysis methods to ensure the collection of representative population-level data, sample-size recommendations for each contaminant and environmental media, biological sampling data, household-survey data, and health-outcome data. Section 1 of the guidelines provides an overview of the Artisanal and Small-Scale Gold Mining (ASGM) process, including a description of the primary contaminants released or discharged during each step of the process. Section 2 describes the process for identifying participating households and individuals within those households that will provide household survey data, environmental sampling data, biomonitoring data, and health-outcomes data. Section 3 provides general guidelines for conducting environmental sampling of soil, dust, sediment, water, fish, and/or agricultural and food products. Section 4 provides general guidelines for collecting biomonitoring samples in blood, urine, hair, or other biological matrices. Section 5 provides general guidelines for evaluating health outcomes using medical exams, health surveys, and diagnostic tests.

Publication Gender Dimensions of Artisanal and Small-Scale Mining : A Rapid Assessment Toolkit(World Bank, 2012-01-01)Artisanal and small-scale mining (ASM) is a global reality. It represents a longstanding and important livelihood for more than 100 million men and women around the world. In some places, communities have practiced it for generations; in other places, the prospect of new mineral finds draws large numbers of people suddenly to mining areas. Whether newly begun or long established, ASM has the potential to help men and women out of poverty when conducted in an informed and responsible way. In different communities, different techniques are used, and men and women share different divisions of labor, risks, and opportunities. ASM assessments, and the recommendations for action arising from these, are critical to the objectives of every ASM stakeholder, whether the large-scale mining (LSM) company seeking to improve the outcomes of its corporate social responsibility programs, a government agency or nongovernmental organization (NGO) seeking to fulfill its policy mandate, a microfinance organization promoting small and medium enterprise development in mining areas, or an association of miners seeking to formalize its activities. The toolkit is comprised of six components: introduction to gender and ASM; the gender and ASM framework; gender and ASM tools; the toolkit in practice; resources; and supplemental CD-ROM.Publication Artisanal Scale Gold Mining(Washington, DC: World Bank, 2022)This framework document provides a pragmatic approach for designing representative studies and developing uniform sampling guidelines to support estimates of morbidity that are explicitly linked to exposure to land-based contaminants from artisanal small-scale gold mining (ASGM) activities. A primary goal is to support environmental burden-of-disease evaluations, which attempt to attribute health outcomes to specific sources of pollution. The guidelines provide recommendations on the most appropriate and cost-effective sampling and analysis methods to ensure the collection of representative population-level data, sample size recommendations for each contaminant and environmental media, biological-sampling data, household-survey data, and health-outcome data. This framework focuses on ASGM activities that are known to use and generate mercury (Hg) as well as other metals, such as arsenic (As) and lead (Pb), depending on the specific ores being mined. A particular concern with Hg is the conversion to methylmercury (MeHg) in aquatic environments, leading to bioaccumulation and biomagnification in fish that may be locally consumed. Exposures to Hg, MeHg, and Pb are strongly associated with neurodevelopmental health outcomes in children. Exposures to Hg and MeHg are also associated with neurological illnesses in adults. Exposures to Pb are associated with renal outcomes in children and adults, and cardiovascular outcomes in adults. Exposures to As are associated with neurodevelopmental health outcomes in children, arsenicosis and skin disorders in children and adults, and potential cancers in adults, including skin, bladder, and lung. The primary objective of this framework is to guide research to assess the relationship between environmental contamination, exposures, and health outcomes related to a subset of contaminants originating from ASGM activities for particularly vulnerable populations (such as children) and the general population within a single household in the vicinity of ASGM sites in low- and medium-income countries. To achieve this objective, biomonitoring and health-outcome data are linked to household-survey and environmental data (for example, soil, dust, water, agricultural products, and fish) at the individual level from an exposed population compared to individuals from an unexposed (reference) population. Data on exposures and health outcomes in the same individual across a representative set of individuals is required to support an understanding of the potential impact of ASGM activities on local populations. These guidelines can also assist in building local capacity to conduct environmental assessments following a consistent methodology to facilitate comparability across ASGM sites in different geographic areas. Sampling strategies and methods are prioritized given information needs, resource availability, and other constraints or considerations. The framework includes a number of supporting appendixes that provide additional resources and references on relevant topics.Publication Transparency in Revenues from Artisanal and Small-Scale Mining of Tin, Tantalum, Tungsten and Gold in Burundi(World Bank, Washington, DC, 2016-01)Burundi has a wide range of mineral deposits of which tin, tantalum and tungsten ores, along with gold, are its primary mineral exports. Burundi’s geological endowment also includes nickel, rare earths, vanadium, and construction materials. The majority of mineral extraction is carried out by artisanal and small-scale mining (ASM) which is officially structured through cooperatives. Tin, tantalum, tungsten (from the minerals cassiterite, tantalite and wolframite and often referred to as the ‘3Ts’) and gold are the primary minerals mined and exported. Improvements in the gold sector are where the Burundian Government stands to make the greatest gains though this is complex to achieve and needs a very practical strategy which is grounded in market and trade realities. Taxation is one element of this but should not be considered in isolation. Engagement with the existing market and finding incentives for formalization is essential. The Government of Burundi should showcase its efforts to improve transparency and traceability. The next step will be to use EITI and iTSCi standards to help to meet the basic needs of artisanal mining communities and to contribute to formalization. This will promote positive perceptions and acceptance of both systems to the benefit of Burundi’s mineral sector and national revenues.Publication Adaptation of the Calculator of Social and Environmental Impacts from Small-Scale Gold Mining in the Amazon(Washington, DC: World Bank, 2023-11-09)Over the past decade, illegal gold extraction has increased significantly in the Amazon region, partly due to the high international prices of this mineral, the less stringent attitude of some countries in relation to the environment and the pursuit of immediate economic opportunities. Furthermore, this illicit activity is closely intertwined with other illegal practices, such as drug trafficking, human trafficking, and the trafficking of endangered species. This has repercussions not just for the region's ecological wealth, but also for the physical well-being of those safeguarding their lands and the health of communities living in proximity to the extraction zones due to the contamination of their rivers and, consequently, their primary sources of food, such as fish. Despite the international effort to recognize the socio-environmental repercussions of this activity, there are still gaps on this issue, mainly due to the economic losses that this activity represents.Publication Mining Together : Large-Scale Mining Meets Artisanal Mining, A Guide for Action(Washington, DC, 2009-03)The present guide mining together-when large-scale mining meets artisanal mining is an important step to better understanding the conflict dynamics and underlying issues between large-scale and small-scale mining. This guide for action not only points to some of the challenges that both parties need to deal with in order to build a more constructive relationship, but most importantly it sheds more light on some potential interventions for conflict prevention, management, and even transformation. This guide, then, represents a step in the right direction to start transforming the relationship between large-scale and artisanal miners through win-win solutions that emerge out of the genuine interaction and dialogue of all stakeholders involved: governments, companies, communities, miners and development organizations. Large-Scale Mining (LSM) companies increasingly come across Artisanal and Small-scale Mining (ASM) workers during their exploration or production activities in the developing world. The ASM-LSM relationship is often conflictual because both types of miners compete for the same resource or because they perceive each other as a threat. However the ASM-LSM relationship is now also undergoing a largely positive evolution in part thanks to new Corporate Social Responsibility (CSR) commitments. This guide is the result of this collaboration and provides an informative overview of the growing experiences of the most typical ASM-LSM issues and guidance for appropriate interventions.

Publication Global Economic Prospects, January 2025(Washington, DC: World Bank, 2025-01-16)Global growth is expected to hold steady at 2.7 percent in 2025-26. However, the global economy appears to be settling at a low growth rate that will be insufficient to foster sustained economic development—with the possibility of further headwinds from heightened policy uncertainty and adverse trade policy shifts, geopolitical tensions, persistent inflation, and climate-related natural disasters. Against this backdrop, emerging market and developing economies are set to enter the second quarter of the twenty-first century with per capita incomes on a trajectory that implies substantially slower catch-up toward advanced-economy living standards than they previously experienced. Without course corrections, most low-income countries are unlikely to graduate to middle-income status by the middle of the century. Policy action at both global and national levels is needed to foster a more favorable external environment, enhance macroeconomic stability, reduce structural constraints, address the effects of climate change, and thus accelerate long-term growth and development.Publication Global Economic Prospects, January 2024(Washington, DC: World Bank, 2024-01-09)Note: Chart 1.2.B has been updated on January 18, 2024. Chart 2.2.3 B has been updated on January 14, 2024. Global growth is expected to slow further this year, reflecting the lagged and ongoing effects of tight monetary policy to rein in inflation, restrictive credit conditions, and anemic global trade and investment. Downside risks include an escalation of the recent conflict in the Middle East, financial stress, persistent inflation, weaker-than-expected activity in China, trade fragmentation, and climate-related disasters. Against this backdrop, policy makers face enormous challenges. In emerging market and developing economies (EMDEs), commodity exporters face the enduring challenges posed by fiscal policy procyclicality and volatility, which highlight the need for robust fiscal frameworks. Across EMDEs, previous episodes of investment growth acceleration underscore the critical importance of macroeconomic and structural policies and an enabling institutional environment in bolstering investment and long-term growth. At the global level, cooperation needs to be strengthened to provide debt relief, facilitate trade integration, tackle climate change, and alleviate food insecurity.Publication Carbon Pricing in the Power Sector(Washington, DC: World Bank, 2024-09-09)The number of countries that have announced some type of commitment to net zero emissions has increased very rapidly in recent years, from five in 2018 to over 145 in 2023. Middle and low-income countries must therefore consider policies to both grow and decarbonize their power sectors. A growing number of them are considering carbon pricing instruments (CPIs). However, the path to implementing carbon pricing is fraught with challenges, including financing obstacles, the urgent need to boost supply, and social priorities different from those of more advanced economies with more carbon pricing experience. This report delves deep into the power sector value chain dynamics, demonstrating how well-designed carbon pricing instruments can be instrumental in helping countries reach their decarbonization goals. Focusing on how decisions are made in diverse power sector models in several developing countries, this report establishes that the CPI must be carefully positioned at the right regulation point in the power sector’s value chain—rather than merely adding a burden for the sector. Getting it right can influence everything from power generation options to investment decisions and customers’ behaviors.Publication Digital Africa(Washington, DC: World Bank, 2023-03-13)All African countries need better and more jobs for their growing populations. "Digital Africa: Technological Transformation for Jobs" shows that broader use of productivity-enhancing, digital technologies by enterprises and households is imperative to generate such jobs, including for lower-skilled people. At the same time, it can support not only countries’ short-term objective of postpandemic economic recovery but also their vision of economic transformation with more inclusive growth. These outcomes are not automatic, however. Mobile internet availability has increased throughout the continent in recent years, but Africa’s uptake gap is the highest in the world. Areas with at least 3G mobile internet service now cover 84 percent of Africa’s population, but only 22 percent uses such services. And the average African business lags in the use of smartphones and computers as well as more sophisticated digital technologies that catalyze further productivity gains. Two issues explain the usage gap: affordability of these new technologies and willingness to use them. For the 40 percent of Africans below the extreme poverty line, mobile data plans alone would cost one-third of their incomes—in addition to the price of access devices, apps, and electricity. Data plans for small- and medium-size businesses are also more expensive than in other regions. Moreover, shortcomings in the quality of internet services—and in the supply of attractive, skills-appropriate apps that promote entrepreneurship and raise earnings—dampen people’s willingness to use them. For those countries already using these technologies, the development payoffs are significant. New empirical studies for this report add to the rapidly growing evidence that mobile internet availability directly raises enterprise productivity, increases jobs, and reduces poverty throughout Africa. To realize these and other benefits more widely, Africa’s countries must implement complementary and mutually reinforcing policies to strengthen both consumers’ ability to pay and willingness to use digital technologies. These interventions must prioritize productive use to generate large numbers of inclusive jobs in a region poised to benefit from a massive, youthful workforce—one projected to become the world’s largest by the end of this century.Publication Quantitative Analysis of Road Transport Agreements (QuARTA)(Washington, DC: World Bank, 2013-04-13)Road freight transport is indispensable to international economic cooperation and foreign trade. Across all continents, it is commonly used for short and medium distances and in long distance haulage when minimizing time is important. In all instances governments play a critical role in ensuring the competitive advantage of private sector operators. Countries often have many opportunities to minimize the physical or administrative barriers that increase costs, take measures to enhance the attractiveness and competitiveness of road transport, or generally nurture the integral role of international road freight transport in the global trade logistics industry. Road freight transport is critical to domestic and international trade. It is the dominant mode of transport for overland movement of trade traffic, carrying more than 80 percent of traffic in most regions. Generally, nearly all trade traffic is carried by road at some point. Therefore, the cost and quality of road transport services is of critical importance to trade competitiveness of countries and regions within countries. In fact, road transport is fundamental to modern international division of labor and supply-chain management.
