Socioeconomic Consequences of Mercury Use and Pollution

Abstract In the past, human activities often resulted in mercury releases to the biosphere with little consideration of undesirable consequences for the health of humans and wildlife. This paper outlines the pathways through which humans and wildlife are exposed to mercury. Fish consumption is the major route of exposure to methylmercury. Humans can also receive toxic doses of mercury through inhalation of elevated concentrations of gaseous elemental mercury. We propose that any effective strategy for reducing mercury exposures requires an examination of the complete life cycle of mercury. This paper examines the life cycle of mercury from a global perspective and then identifies several approaches to measuring the benefits of reducing mercury exposure, policy options for reducing Hg emissions, possible exposure reduction mechanisms, and issues associated with mercury risk assessment and communication for different populations.

Building Capacity in Small-Scale Mining Communities: Health, Ecosystem Sustainability, and the Global Mercury Project

The Global Mercury Project (GMP) is an initiative of the United Nations in collaboration with numerous government and nongovernment organizations to promote knowledge and capacity building on the links between small-scale gold mining practices and health, ecosystem, and social factors, and to implement interventions that reduce mercury pollution and exposure caused by mining activities in developing countries. Knowledge regarding the use of mercury and the dynamics of complex environmental, health, socioeconomic, and cultural conditions in and surrounding small-scale mining sites is particularly needed for the purpose of developing appropriate community-based measures to reduce mercury-related problems. GMP strategies aim to build upon local knowledge and practices to train miners on the use of cleaner and affordable technologies of mining and mineral processing in order to minimize negative impacts. The initiative is especially proactive in facilitating transdisciplinary and participatory models of community interaction, involving local, regional, and international stakeholders in each of the strategy design, community assessment, and community intervention phases. The six participating countries are Brazil, Indonesia, Lao People’s Democratic Republic, Sudan, Tanzania, and Zimbabwe. This article outlines GMP’s objectives and scope of activities and also highlights achievements, challenges, and opportunities for future development.

Mercury Reduction in Munhena, Mozambique: Homemade Solutions and the Social Context for Change

Abstract The health and environmental impacts of artisanal gold mining are of growing concern in Munhena, Mozambique, where more than 12,000 people are involved in such activities. Gold is extracted using mercury amalgamation, posing a considerable threat to human and environmental health. A pilot project ascertained the feasibility of reducing mercury use and emissions by promoting control measures utilizing local resources. Retorts were fabricated with local materials. Training workshops introduced the homemade retorts, and a portable mercury monitor revealed effective mercury reduction. Barriers to widespread technology adoption include poverty, lack of knowledge and trust, and the free supply of mercury from private gold buyers. Homemade retorts are inexpensive and effective, and miners could benefit by building community amalgamation centers. The government could play a greater role in gold purchasing to reduce mercury pollution.

Shifting Formalization Policies and Recentralizing Power: The Case of Zimbabwe’s Artisanal Gold Mining Sector

In the 1990s, government authorities in Zimbabwe introduced internationally praised policies to formalize the artisanal and small-scale mining sector, using a combination of district-administered and nationally administered licensing and capacity-building measures. While “decentralization” efforts in the 1990s and early 2000s were hampered by insufficient resource and power transfers, the model was seen by environmental scholars as a source of optimism. However, as economic crisis deepened in the 2000s, national officials (a) revoked the power of Rural District Councils to regulate riverbed alluvial gold panning and (b) increased barriers to formally licensed small-scale primary ore mining. This article examines the recentralization of power in this growing informal sector, exploring how heavy-handed implementation of national reforms contributed to livelihood insecurity. The study emphasizes how national officials invoked “formalization” rationales for mining policy shifts that obscured their underlying political and economic drivers, disempowering local district authorities and deepening the marginalization of informal livelihoods.

Implications of the Minamata Convention on Mercury for informal gold mining in Sub-Saharan Africa: from global policy debates to grassroots implementation?

In October 2013, after years of negotiation, governments from 92 countries signed a historic agreement called the Minamata Convention on Mercury, establishing mandatory measures to curb mercury use and pollution. Article 7 of the Convention stipulates that governments must create National Action Plans to reduce and where feasible eliminate mercury use in artisanal gold mining, a rapidly growing informal sector in much of Africa, with strategies to be monitored by the Convention Secretariat. The purpose of this study is to critically analyze the implications of the Minamata Convention for the artisanal mining sector in Sub-Saharan Africa, which currently depends upon mercury amalgamation for gold extraction. Our analysis draws on examples from Zimbabwe and Tanzania, countries with divergent political challenges but both with expanding artisanal mining sectors. We argue that a paradigm shift is needed to address intertwined technological, political and socio-economic challenges facing marginalized populations in mining communities. We highlight why meeting the Convention targets requires that international donors and national policymakers proactively engage—rather than vilify—artisanal miners who use mercury, prioritizing local knowledge and collaborative community-based decision making to develop effective pollution abatement initiatives in gold mining regions. We further argue that gender-sensitive grassroots empowerment initiatives including microfinance programs are vital to facilitate adopting cleaner technology, as required by Article 7. Finally, the analysis underscores the need for fundamentally reforming national mining policy priorities, recognizing marginalized mining communities’ resource rights and tackling livelihood insecurity as part of efforts to implement the Minamata Convention. In considering what ‘grassroots’ implementation could mean, the article contributes to a growing body of scholarship calling attention to fairness and equity concerns in order to achieve the aims of global environmental agreements.

Mapping Spaces of Environmental Dispute: GIS, Mining, and Surveillance in the Amazon

Recent scholarship has urged increased attention to how advances in geographical information systems (GIS) technology can more equitably help to bridge gaps between the theory and practice of environmental protection and dispute resolution. This study brings new evidence to burgeoning debates in the Amazon, examining how a United Nations (UN) development initiative developed mapping systems in a shifting political climate for environmental governance while conducting campaigns with peasant miners to address environmental management. Amendments made in 2002 to the Brazilian Forest Code established natural preserves according to the geographic features of watersheds. The laws deter commercial land use on preserves, imposing strict penalties where artisanal mining is widely prevalent as a livelihood. The UN program utilized GIS and Shuttle Radar imagery to map the contested areas according to legal definitions and engaged stakeholders to discuss political implications. In 2006, new reforms made such mapping tools even more controversial—and urgent—with amendments that created opportunities for bringing “informal” mining into the legal sphere, theoretically allowing “spaces of exception” where mining can be legitimated. Our multimethod study underscores the need for appreciating diverse understandings of ecologically sensitive zones and empowering rural communities to take ownership over geospatial technologies in addressing environmental challenges. Although maps produced using the proposed methods could be useful, dominant advocacies that champion GIS as an enforcement tool often undermine local trust, inflame tensions, and render alternative “grassroots GIS” strategies impracticable. We examine the contexts, powers, limitations, and risks of the UNs technical intervention, exploring how competing views of environmental controversy lead to divergent perspectives on the politics of GIS “knowledge translation” and mapping itself.

Deforestation: call for justice, not militarization.

SIR — As a recent policy adviser to the United Nations in a programme intended to address environmental threats in the Amazon, I would caution readers of your Special Report ‘Brazil goes to war against logging’ (Nature 452, 134–135; 2008). Although this analysis of Brazil’s “militarystyle crackdown on deforestation” is valuable, it perpetuates some perilous assumptions. You aptly note that mining on the fringes is among the problems, but I would question some of the solutions you suggest. Urging international donors to help national governments such as Brazil to fund ‘traditional’ policies for enforcement neglects the reality that local governance agents, not national enforcers, can be more appropriate custodians; foreign donors frequently make this mistake. Also, there needs to be greater global awareness of the unwanted consequences of the so-called traditional policies of eco-militarization, which have wrought pervasive problems not only in the Amazon but worldwide. Police interference in indigenous people’s lives can have devastating effects, often leading to more environmental harm rather than less. My own experience with peasants who mine illegally in conservation areas suggests that resentment of the government drives illegality and marginalization. For example, indigenous groups in the Amazon captured more than 600 hostages in the past two years, protesting against injustices with regards to mining rights. One tribe took a UN worker and four others hostage a few months ago, angry that the government and international agencies ignored their resource claims; the government sent in police troops instead. That tribe was seeking the rights to mine its land — but only a multinational corporation was granted those rights. Brazil has millions of peasant (‘artisanal’) miners, but licences only very rarely go to poorer communities. Some 337 large-scale commercial mining permits violate Brazilian law, falling within 28 federal conservation areas; another 5,283 pending applications also impinge on federal conservation areas. Environmental violations are pervasive in both legal and illegal scenarios — and the concept of legality itself is blurred. It is time to politicize the Amazon, not militarize it. Conservation advocacies should focus on socio-economic empowerment of vulnerable populations. Military enforcement should be a rare last resort. It is time to listen to the poorest ‘illegal’ people and let them shape policy. Creating new megareserves, even if appropriate, is rarely an effective solution. Combating deforestation requires helping workers to find livelihoods while participating equitably in the intricate politics of nature. Samuel J.

Decolonising Online Development Studies?: Emancipatory Aspirations and Critical Reflections: A Case Study

Abstract Academics in high-income countries are increasingly launching development studies programmes through online distance learning to engage practitioner-students in low-income countries. Are such initiatives providing opportunities to critically tackle social injustice, or merely ‘mirroring’ relations of global inequality and re-entrenching imperial practices? Building on recent scholarship addressing efforts to ‘decolonise development studies’ and the complex power dynamics they encounter, we reflect on this question by analysing experiences of faculty and students in a United Kingdom-based online development studies programme, focusing particularly on perspectives of development practitioner-students working from Africa. We discuss barriers to social inclusivity – including the politics of language – that shaped participation dynamics in the programme as well as debates regarding critical development course content, rethinking possibilities for bridging counter-hegemonic development scholarship with practice-oriented approaches in a range of social contexts. Our analysis unpacks key tensions in addressing intertwined institutional and pedagogic dilemmas for an agenda towards decolonising online development studies, positioning decolonisation as a necessarily unsettling and contested process that calls for greater self-reflexivity.

Knowledge sharing in artisanal mining communities : mercury, technology and sustainability in developing countries

As gold has risen in value and artisanal gold mining has increased in many low income countries, there has been an increasing need for sustainable development models that promote environmental protection while enhancing the contribution of this activity to poverty alleviation. Artisanal mining provides a critical source of income for an estimated 15 million poverty-driven miners around the world, mainly in Africa, Asia and Latin America. However, its environmental impacts are often extensive, with mercury pollution posing major threats to human health and diverse ecosystems. 1000 tonnes of mercury are polluted annually into the environment due to mercury misuse in artisanal gold mining. This paper reviews community development models pioneered by local community practitioners and international experts as part of an initiative by the United Nations Industrial Development Organization, which can help to overcome environmental, social and economic challenges. We discuss the introduction of various technical options, from simple innovations that allow mercury containment, recycling and re-use, and also emphasize the importance of technologies of grinding and crushing that can be developed from local materials to further enhance income potential. While various past development efforts have sought to reduce mercury-related problems, we conclude that sustainable development should seek to intertwine knowledge-sharing on environmental goals with concrete ways of improving economic well-being. We demonstrate how such models of knowledge-sharing can help to catalyze local innovation, technology-sharing and community organization. We also discuss how this knowledge can be applied by governments to create capacitybuilding policies as well as regulations that support sustained improvement in mining standards.

Artisanal Gold Mining and Farming: Livelihood Linkages and Labour Dynamics after Land Reforms in Zimbabwe

Abstract While the rural development consequences of Zimbabwe’s Fast Track Land Reform Programme have been heavily debated, there is a dearth of literature focusing on the post-land reform inter-relations between artisanal and small-scale gold mining (ASGM) and farming. This article discusses the growing ASGM sector, encapsulated by the phrase ‘mari yaputika’/‘gold has detonated’, examining the impacts of ‘liberating’ mineral resources in farming areas previously inaccessible to the rural poor. Drawing on research in Mhondoro Ngezi District, we argue for more subtle understandings of smallholder farming/ASGM linkages in relation to changing labour and class dynamics, challenging accounts that under-recognise the multifaceted interconnectedness of artisanal mining and farming.
