Small-scale mining in Ghana: The government and the galamsey

This paper argues that the current formalization system for small-scale gold miners in Ghana has been undermined and the small-scale mining laws no longer capture the reality of the sector’s activities. The paper will examine the small-scale mining system and shows that registered and unregistered actors operate not only in parallel but are actually intertwined and highly dependent on one another. The paper shows that the perceived dichotomy of formal and informal actors in the sector does not actually exist. The sector has instead evolved into a highly intertwined group of semi-formal sectors operating with varying degrees of legal registrations. The paper concludes that political leniency and law enforcement corruption has resulted in a booming small-scale gold system under poor government control. The paper recommends that politicians move to enact reforms to regularize the small-scale mining sector and curtail ubiquitous environmental and occupational safety problems. Anti-corruption initiatives and law enforcement reforms are the most urgent. However, reforming the laws is also necessary to capture and regulate the technological innovations the sector is currently using.     

Corporate Social Responsibility (CSR) for exploration: Consultants,companies and communities in processes of engagements

Over the last fifteen years, large-scale mining companies have started engaging in Corporate Social Responsibility (CSR), with the aim of contributing to developing local communities affected by their operations. Large-scale mining companies, together with the World Bank, have formulated voluntary principles and benchmarks to guide these company–community relations. Recently, it has been argued that CSR is also crucial in the early stages of exploration. Nowadays, mining consultants propagate a process approach to company–community relations, from early exploration to post-mining planning.     

Corporate social responsibility in the mining industry: Perspectives from stakeholder groups in Argentina

Since the liberalisation of its investment regime in the 1990s, Argentina has seen a rise in foreign direct investment into large-scale exploration and exploitation of mineral resources. However, many social groups (local communities, grassroots movement and the church) often strongly oppose new mining projects on the grounds of environmental, ethical and economic concerns. In a situation marked by widespread conflict, mining companies continue operating and develop Corporate Social Responsibility (CSR) initiatives which are often promoted as a means of contributing to the sustainability and development of the nation. The paper develops a framework to highlight how the principles of stakeholder theory could be used as conceptual and practical guidance for conflict-resolution oriented CSR policies. The framework is further used to analyse two case studies of conflictive mining projects in Argentina. The paper explores how key stakeholders perceive contribution of CSR to welfare and the socio-economic development of mining communities and sustainable development of the nation. It demonstrates that institutional and social stakeholder networks often strongly oppose the idea of voluntary self-regulation implied by CSR in situations characterised by weak governance. Even though the CSR of companies could be improved in areas of corporate communication, transparency, stakeholder engagement and dialogue, it is not seen as a panacea for the social conflicts in the sector.     

A SWOT analysis of environmental management practices in Greek Mining and Mineral Industry

Over the last two decades, mining and mineral exploration companies have adopted various environmental management practices in response to society’s pressure for better environmental protection. The literature highlights a number of benefits and challenges for companies adopting environmental management practices with the Greek Mining and Mineral Industry (GMMI) facing similar issues. In order to analyze the challenges faced by the GMMI, a Strengths, Weaknesses, Opportunities and Threats (SWOT) analysis was conducted, which examined the strengths, weaknesses, opportunities and threats faced by the industry when adopting environmental management practices. The analysis prescribes policy recommendations both for the government and industry which, if adopted, could facilitate improved environmental performance.     

The Environmental sustainability of mining in Australia: key mega-trends and looming constraints

At first ‘sustainable mining’ could be perceived as a paradox—minerals are widely held to be finite resources with rising consumption causing pressure on known resources. The true sustainability of mineral resources, however, is a much more complex picture and involves exploration, technology, economics, social and environmental issues, and advancing scientific knowledge—predicting future sustainability is therefore not a simple task. This paper presents the results from a landmark study on historical trends in Australian mining, including ore milled, ore grades, open cut versus underground mining, overburden/waste rock and economic resources. When complete data sets are compiled for specific metals, particular issues stand out with respect to sustainability—technological breakthroughs (e.g. flotation, carbon-in-pulp), new discoveries (e.g. uranium or U), price changes (e.g. Au, boom/bust cycles), social issues (e.g. strikes), etc. All of these issues are of prime importance in moving towards a semi-quantitative sustainability model of mineral resources and the mining industry. For the future, critical issues will continue to be declining ore grades (also ore quality and impurities), increased waste rock and associated liabilities, known economic resources, potential breakthrough technologies, and broader environmental constraints (e.g. carbon costs, water). For this latter area, many companies now report annually on sustainability performance—facilitating analysis of environmental sustainability with respect to production performance. By linking these two commonly disparate aspects—mining production and environmental/sustainability data—it becomes possible to better understand environmental sustainability and predict future constraints such as water requirements, greenhouse emissions, energy and reagent inputs, and the like. This paper will therefore present a range of fundamental data and issues which help towards quantifying the resource and environmental sustainability of mining—with critical implications for the mining industry and society as a whole.     

Exploring discourses on international environmental regime effectiveness with Q methodology: a case study of the Mediterranean Action Plan

Extensive research has been done on the 'high politics' of negotiations of international environmental agreements. However, little attention has been paid to the effectiveness of their implementation after coming into force. Effectiveness cannot be easily measured, since different stakeholders use different criteria as the basis of their opinion. The purpose of this study is to investigate discourses on the effectiveness of an international environmental regime. The regime chosen is the Mediterranean Action Plan (MAP) - and its legal framework, the Barcelona Convention - which was established in 1975 under the aegis of the United Nations Environment Programme (UNEP). Q methodology was used to reveal discourses on the effectiveness of UNEP/MAP. After collecting relevant literature and identifying the stakeholders, 25 in-depth interviews were conducted. The stakeholders were from the Secretariat of the Convention, academia, NGO workers, and others that studied or knew the subject well. From these interviews 294 statements were extracted, from which 44 were finally selected to be used in the Q study. The interviewees were approached for the second time to complete the Q sorts. This study revealed four distinct discourses concerning the effectiveness of international environmental regimes. It concludes that there is no one 'right' way of defining effectiveness and that no approach can provide more than a partial evaluation of the overall effectiveness of a regime.     

AESTHETIC PREFERENCE FOR WATER RESOURCE PROJECTS: AN APPLICATION OF Q METHODOLOGY1

ABSTRACT Many of the resources generating aesthetic and visual benefits are publically owned and their optimum use and development depends upon public investment. Traditionally, public investment decisions have been couched in economic terms requiring quantitative measurement of benefits and costs. Since many of the benefits these resources provide are not consumed when they are enjoyed, the total contribution of the resource is imperfectly measured in the usual market sense. Thus, if the provision of these public goods is left to the conventional market mechanism, less than socially optimal investment may occur. This study was designed to investigate whether aesthetic preferences related to water projects could be determined, and whether they differ among different groups of people. A Q sort of 44 photographs of a wide variety of water development projects was conducted with two groups, i.e., photographers (aesthetic man) and town assessors (economic man). The resultant analysis identified two significant factors. Factor 1 provided insight into a hypothesis of nature dominant or man dominant scenes. Factor 2 indicated that the respondents had a negative preference for projects which were in varying stages of completion or appeared to be polluted. Preferences were consistent between the two groups tested. The test revealed that people do not necessarily equate only naturalness with aesthetic appeal, but will accept development as aesthetic, provided that it is designed to complement the natural landscape.

KLUM@GTAP: Introducing Biophysical Aspects of Land-Use Decisions into a Computable General Equilibrium Model a Coupling Experiment

In this paper, the global agricultural land use model Kleines Land Use Model is coupled to an extended version of the computable general equilibrium model (CGE) Global Trade Analysis Project in order to consistently assess the integrated impacts of climate change on global cropland allocation and its implication for economic development. The methodology is innovative as it introduces dynamic economic land-use decisions based also on the biophysical aspects of land into a state-of-the-art CGE; it further allows the projection of resulting changes in cropland patterns on a spatially more explicit level. A convergence test and illustrative future simulations underpin the robustness and potentials of the coupled system. Reference simulations with the uncoupled models emphasise the impact and relevance of the coupling; the results of coupled and uncoupled simulations can differ by several hundred percent.

立地条件对麻栎人工林碳储量的影响

在江淮山地丘陵区,通过样地调查,研究了坡向和w对麻栎（Quercusacutisima）人工林系统碳密度及其空间分布的影响。结果表明：阴坡（SHS）树木碳密度显著高于阳坡（sus）（P〈0．05）,Wt镕i《1低的立地（sus）树木碳密度显著高于w、高的（suss）（P〈0．05）。3种立地条件下麻栎各器官碳密度分配均为：干碳密度〉根碳密度〉枝碳密度〉叶碳密度。SUS和SHS林木分配较多的碳同化物供给树干生长,SUSS林木分配较多的碳同化物供给根系和枝的生长。凋落物碳密度在SUS和SHS之间没有显著差异（P〉0．05）,而SUSS则显著低于SUS和SHS（JPl〈0．05）。整个剖面（0～50cm）土壤有机碳密度SHS显著高于SUS和SUSS（P〈O．05）,SUS和SUSS之间没有显著差异（P〉0．05）。麻栎人工林系统总碳密度大小为SHS（146．9t·hm^2。）〉SUS（116．9t·hm^-2）〉SUSS（102．6t·hm^-2）,SHS显著高于其他2种立地条件（P〈0．05）,SUS与SUSS之间没有显著差异（P〉0．05）。3种立地条件下均为土壤碳密度〉树木碳密度〉凋落物碳密度,凋落物碳密度占林分总碳密度的比例仅为2．1％～3．6％。SUS和SHS土壤碳密度占林分总碳密度的比例低于SUSS,而树木碳密度占林分总碳密度比例则相反。由此可见,在江淮山丘区,w较低的阴坡（SHS）最有利于麻栎人工林碳储量的累积,相对于w、较高的立地（suss）,较低的Wf±镕6砾1（sus）更有利于树木碳储量的增加。
