Green accounting and sustainability of the Peruvian metal mining sector

This paper estimates the true economic income of Peru’s metal mining sector for the period 1992–2006, using a model of green economic income based on Hamilton (2000). The total depletion of natural capital caused by metal mining is calculated by estimating, on the one hand, the depreciation of mining resources (using the Hotelling rent approach) and, on the other, the environmental degradation provoked by metal mining activities. The results show that the total loss of natural capital represents between 31% and 51% of the metal mining GDP and between 2% and 4.9% of Peru’s GDP. On the other hand, correcting the usual GDP measure produced by the traditional National Account System (NAS) for the total loss of natural capital caused by mining activities shows that the GDP traditional measure overestimated by 51–64% the true economic income generated by Peruvian's metal mining sector during the period 1992–2006. The importance of the generation, taxation, and disposition of mining economic rents for Peru’s sustainable development in the future is also discussed.     

A conceptual approach to model sand–gravel extraction from rivers based on a game theory perspective

Sand–gravel mining is a significant parameter of economic development and social welfare function in modern societies. As demand for aggregate increases in construction industry, conflicts for the availability of the resource and environmental impacts become more intense. The present paper describes the contested status quo in riverbed sand–gravel mining activities with an example from Greece, as a case study. The scope is to propose a methodology about good governance of the mining sector that promotes a sustainable sharing of aggregate resource by securing environment and safekeeping revenues in the mining trade market.     

Spatial Convergence in Major Dissolved Ion Concentrations and Implications of Headwater Mining for Downstream Water Quality

Spatial patterns in major dissolved solute concentrations were examined to better understand impact of surface coal mining in headwaters on downstream water chemistry. Sixty sites were sampled seasonally from 2012 to 2014 in an eastern Kentucky watershed. Watershed areas (WA) ranged from 1.6 to 400.5 km² and were mostly forested (58%–95%), but some drained as much as 31% surface mining. Measures of total dissolved solutes and most component ions were positively correlated with mining. Analytes showed strong convergent spatial patterns with high variability in headwaters (<15 km² WA) that stabilized downstream (WA > 75 km²), indicating hydrologic mixing primarily controls downstream values. Mean headwater solute concentrations were a good predictor of downstream values, with % differences ranging from 0.55% (Na⁺) to 28.78% (Mg²⁺). In a mined scenario where all headwaters had impacts, downstream solute concentrations roughly doubled. Alternatively, if mining impacts to headwaters were minimized, downstream solute concentrations better approximated the 300 μS/cm conductivity criterion deemed protective of aquatic life. Temporal variability also had convergent spatial patterns and mined streams were less variable due to unnaturally stable hydrology. The highly conserved nature of dissolved solutes from mining activities and lack of viable treatment options suggest forested, unmined watersheds would provide dilution that would be protective of downstream aquatic life.     

Industry Response to the Challenge of Sustainability: The Case of the Canadian Nonferrous Mining Sector

/ The paper investigates how the Canadian nonferrous sector is tackling the challenge of sustainable development. Although there is no consensus as to what sustainable development means in practice for management in the sector, at least three dimensions must be taken into account: (1) metals are recyclable, the availability of this resource is not a concern for the foreseeable future; (2) the need to minimize environmental impacts of metals exploration, extraction, transformation, consumption, and recycling; and (3) production activities should not be socially or culturally disruptive. The nonferrous mining industry faces several environmental problems. Some of the most significant are acid mine drainage, sulfur emissions, recycling, and metals toxicity. The industry has developed a number of responses to address these specific concerns as well as other more general challenges. Six strategies are described and analyzed: (1) research and development, (2) an effort of consensus building among stakeholders known as the Whitehorse Mining Initiative, (3) international networking, (4) active involvement in the development of environmental management standards, (5) management reorganization and (6) voluntary agreements. The importance of external factors in the shaping of corporate environmental management practices is discussed, in particular the role of government. Progress has been achieved in three areas: (1) managerial practices and organization, (2) reducing the impacts of ongoing operations and (3) minimizing future liabilities, but two significant fields of conflict remain, namely mining in wilderness areas and projects on aboriginal lands.KEY WORDS: Canada; Environmental management; Minerals industry; Nonferrous metals; Sustainable development; Whitehorse Mining Initiative     

Towards greening a university campus: The case of the University of Maribor, Slovenia

The environmental performance of the University of Maribor (Engineering Campus) has been assessed on a life cycle basis. The following activities have been considered in the study: the use and operation of lecture theatres (construction and maintenance, heating, lighting and water consumption) and day-to-day consumption of sundries (paper and plastic bottles). The results indicate that the heating and construction of buildings are the ‘hot spots’ in the system, for most environmental impacts. Different waste management options for the plastic and paper, including recycling, incineration and landfill, have also been compared for environmental impacts and economic costs. The option combining 70% recycling, 29% incineration and 1% landfill has been found to be most economically and environmentally sustainable.

Land Use-Based Landscape Planning and Restoration in Mine Closure Areas

Landscape planning and restoration in mine closure areas is not only an inevitable choice to sustain mining areas but also an important path to maximize landscape resources and to improve ecological function in mine closure areas. The analysis of the present mine development shows that many mines are unavoidably facing closures in China. This paper analyzes the periodic impact of mining activities on landscapes and then proposes planning concepts and principles. According to the landscape characteristics in mine closure areas, this paper classifies available landscape resources in mine closure areas into the landscape for restoration, for limited restoration and for protection, and then summarizes directions for their uses. This paper establishes the framework of spatial control planning and design of landscape elements from “macro control, medium allocation and micro optimization” for the purpose of managing and using this kind of special landscape resources. Finally, this paper applies the theories and methods to a case study in Wu’an from two aspects: the construction of a sustainable land-use pattern on a large scale and the optimized allocation of typical mine landscape resources on a small scale.     

Innovation for sustainable development in artisanal mining: Advances in a cluster of opal mining in Brazil

The objective of this article is to understand how the promotion of clusters of small economic agents in the gem sector has brought some improvements in the economic, social and environmental conditions in the mining sector and activities related to it. The research provides policy and theoretical contributions to the field of gem production, as well as enhances understanding of the under researched opal production in Brazil. It argues that government funding and technical support dedicated to the development of mining clusters, i.e. working with small economic agents as a whole and not individually, could promote not only more economic development, but also effectively incorporate social and environmental issues, such as workers safety, water management and tailings recycling. The argument is based on an evaluation of environmental, economic, social and institutional aspects of the opal mining cluster in Pedro II municipality, Piauí state. The results suggest that some formalisation of existing practices and adequate policies have triggered innovation with some positive effects on the performance of artisanal mining. Nevertheless, there are indications that if decision-makers plan to make this cluster more sustainable, they will have to include other issues in the debate including developing substituting economic activities.     

Informality in mineral resource management in Asia: Raising questions relating to community economies and sustainable development

Informal mining activities provide livelihoods for millions of poor in mineral‐rich developing countries. Yet, they continue to remain one of the least understood areas in mineral resource management. While its poverty reduction potential is acknowledged, the heterogeneous forms of mining that come under its purview are not well discussed. This article aims to draw attention to the politics of definition by briefly introducing the reader to the nomenclature currently used to describe such mining activities. Then the article examines the nature of informality that justifies the name, and then illustrates the claim by documenting a range of informal mining practices in India with cited examples from other Asian countries. It illustrates the variations in social‐economic, technical and legal characteristics, by putting such mining in a community and participatory framework. Finally, the article discusses ways to move towards sustainable development with community participation in mineral‐rich areas of developing countries.     

Environment and development in the Republic of the Marshall Islands: Linking climate change with sustainable fisheries development

The Republic of the Marshall Islands (RMI) is a major custodian of one of the ocean's major natural resources: tuna. The commercial tuna fisheries sector is the most important economic sector in the RMI and is thus a substantial contributor to this tiny island nation's GDP. Tuna catch and its associated revenues has fluctuated in line with climatic events such as the El Niño/La Niña Southern Oscillation (ENSO) and, in the last decade, national fisheries development policies have begun to capitalize on the positive effects that ENSO warm events have had on the tuna populations. However, global warming is expected to have a significant impact on ENSO, and not necessarily in positive ways. This paper will focus on the relationship between environment and economic development in the RMI fisheries sector. In particular, the linkages between global warming and its effects on the tuna fisheries sector must be better understood and uncertainties accounted for so that impacts are appropriately addressed and integrated into sustainable fisheries development policies. Conclusions reached are that new fisheries development strategies that emphasize environmental‐based planning are required. The emerging ecosystem‐based approach to fisheries management is a start, as are the various international initiatives in furthering our understanding of the linkages between climate and ocean systems currently underway.     

Economic impacts of mining

The mining industry can be critical to a nation's economic well-being. Impacts may be felt on a national or regional level, with their significance dependent in part on the resources under development as well as existing government policies. This paper examines typical economic consequences of mining and how such impacts are being felt in the so-called transitional economies of Asia and Europe. Clearly, while mining continues to play an important role in the economies of Russia, China, Vietnam and other transitional nations, the nature and impacts of mining are different by virtue of years of centralized planning in the industry and the use of non-economic measures of efficiency. The changing character of mining is today opening up new opportunities for foreign investment and technology assistance.     

Mining investment and regional development: A scenario-based assessment for Northern Sweden

The way in which mineral development contributes to economic development in the region where it takes place is important for the mining industry’s relations to the local community. The purpose of this paper is to provide an assessment of the regional-economic impacts of a large-scale contemporary iron ore project in Northern Sweden (including two new mines, two processing plants, and one pellet plant). The regional input-output model rAps, provided by the Swedish government agency NUTEK is used, and it explicitly addresses the linkages between demographic development, the labour market, industrial production and the municipal finances in a consistent modelling framework. The simulation results suggest an average employment multiplier of about 2-2.5 during the maximum production phase, indicating that for every 100 jobs in mining about 100-150 jobs are supported elsewhere in the local economy. The positive impacts in this case are made possible in large because of the existing mining cluster and local suppliers in northern Sweden. Still, these results are perhaps best viewed as an indication of the potential for local economic development as they neglect, for instance, potential supply constraints (e.g., attracting the necessary labour force, road infrastructure, etc.). Specific policies to further strengthen the regional linkage effects may therefore be necessary in order for this potential to be realized in practice, and attention would preferably be paid to policy measures that have positive external spillover effects on the surrounding geographical area.     

From climate change impacts to adaptation: A development perspective for India

India has good reasons to be concerned about climate change as it could adversely affect the achievement of vital national development goals related to socio‐economic development, human welfare, health, energy availability and use, and infrastructure. The paper attempts to develop a framework for integrated impact assessment and adaptation responses, using a recently built railroad coastal infrastructure asset in India as an example. The framework links climate change variables — temperature, rainfall, sea level rise, extreme events, and other secondary variables — and sustainable development variables — technology, institutions, economic, and other policies. The study indicates that sustainable development variables generally reduce the adverse impacts on the system due to climate change alone, except when they are inadequately applied. The paper concludes that development is a vital variable for integrated impact assessment. Well crafted developmental policies could result in a less‐GHG intensive future, enhanced adaptive capacities of communities and systems, and lower impacts due to climate change.     

The mining industry in the European Union: Analysis of inter-industry linkages using input–output analysis

Input–output modelling is a useful tool in policy analysis and economic planning. This methodology is used to detect the inter-industry linkages known as forward and backward linkages. Examination of these measures provides one mechanism for identifying “key” or “leading” sectors. The main objective of this paper is to measure the linkages of the mining and quarrying industry in the European Union (EU) and to determine if any of the industry subsectors can be considered key sectors. The paper shows that three subsectors can be considered key sectors: the mining of coal and lignite and extraction of peat in Germany; mining of metal ores in Sweden; and other mining and quarrying in Austria, Denmark and Spain. These sectors are more stimulated by overall industry growth than other sectors and have greater impacts in terms of investment expenditures on the national economy than other sectors. The values of the forward and backward linkages show that the mining and quarrying is an industry that would be stimulated by an increase in a regional economy's production more than other sectors, while an increase in the mining and quarrying industry's output would not stimulate this regional economy more than an increase in other sectors.     

A framework for sustainable invasive species management: Environmental,social, and economic objectives

Applying the concept of sustainability to invasive species management (ISM) is challenging but necessary, given the increasing rates of invasion and the high costs of invasion impacts and control. To be sustainable, ISM must address environmental, social, and economic factors (or “pillars”) that influence the causes, impacts, and control of invasive species across multiple spatial and temporal scales. Although these pillars are generally acknowledged, their implementation is often limited by insufficient control options and significant economic and political constraints. In this paper, we outline specific objectives in each of these three “pillars” that, if incorporated into a management plan, will improve the plan’s likelihood of sustainability. We then examine three case studies that illustrate how these objectives can be effectively implemented. Each pillar reinforces the others, such that the inclusion of even a few of the outlined objectives will lead to more effective management that achieves ecological goals, while generating social support and long-term funding to maintain projects to completion. We encourage agency directors and policy-makers to consider sustainability principles when developing funding schemes, management agendas, and policy.

Mining development,income growth and poverty alleviation: A multiplier decomposition technique applied to China

Mining has grown rapidly and is expected to continue to develop solidly in the future with the economic development in China. Based on this trend, how an increase in the outputs of mining sectors affects household income and poverty alleviation is an issue worthy of study. A multiplier decomposition method within a social accounting matrix (SAM) framework shows the linkages through which a mining sector's output contributes to household income growth and poverty alleviation. The decomposition applied to China reveals that mining development has more significantly positive impacts on the high and middle income household than low income household. Moreover, the decomposition incorporated with the Foster, Greer and Thoerbecke (FGT) poverty measure shows that the ‘coal’ sector contributes most to poverty alleviation and the low income household group, which has the biggest poverty rate, is the smallest beneficiary from the mining development. Thus, the policy implication is proposed that the government should give appropriate adjustment on the distribution of income between rich and poor households and help the unskilled human capital from the household group at a low income level to handle advanced technology of mining through education and training to reduce poverty more effectively.     

A multicriteria model for planning agricultural regions within a context of groundwater rational management

Current international research focuses on topics like sustainable development, regional planning, environmental decision making and implementation, biodiversity conservation plus a number of other relevant issues, especially at times of economic crisis as today. Economic growth and environmental protection can go hand in hand, provided that decision makers develop and use tools and insights targeting in the implementation of successful and robust long term policies. This paper was developed in the framework of a European research project and implements a Multicriteria Mathematical Programming model that optimises the sustainable management of agricultural regions taking in account the available resources (land, labour, capital) and environmental parameters (agrochemicals, water consumption). The model achieves the optimum farm plan in the area combining different criteria to a utility function under a set of constraints and the spatial integration of the vulnerability maps of the regions into the model enables the regional authorities to design policies for the optimal agricultural development and the groundwater protection from the agricultural land uses. Furthermore, the model is used to simulate different scenarios and policies by the local stakeholders, due to changes on different social, economic and environmental parameters. In this way the decision makers can achieve alternative farm plans and agricultural land uses as well as to estimate economic, social and environmental impacts of different policies. The model has been applied to an agricultural region in Northern Greece and proved to be a valuable tool in the implementation of environmental policies and actions, especially in agricultural regions in a delicate balance as the study area.     

Sustainable Mining in the European Union: The Legislative Aspect

This paper is a review of the community legislation of the European Union (acquis communautaire) with regard to the mineral extractive industry. It highlights the existing inconsistencies of the acquis, which require correction. Historically, the mining industry has received privileged treatment within the European Community. The treaties declare the promotion of a policy of using natural resources prudently and rationally to avoid their unconsidered exhaustion. However, mining is excluded from the scope of major environmental directives or reserves a certain freedom for interpretation. This has led to an increasing number of related cases at the European Court of Justice.The regulatory tools of the environmental acquis are rather diverse in controlling the emission sources, the pollution pathways, and the impacted receptor media through administrative measures or assigning environmental quality targets. A combined approach is needed for controlling the environmental impacts of the extractive industries. The amendment of the Seveso II Directive, the elaboration of a reference document on best available techniques and the preparation of a wide-scope directive on mining waste management might provide a frame for the elimination of the above discrepancies. In addition, a coherent European Community policy based on the balanced consideration of economic, environmental, and social aspects could ensure a sustainable development of the mining industry.

Environmental and socioeconomic impacts of cobblestone quarries in Addis Ababa and implication for resource use efficiency,environmental quality,and sustainability of land after‐use

The extraction of construction material in Addis Ababa has been a source of public conflict for many years, especially in terms of quarry operation, displacement of people, rehabilitation of quarry sites, and land after‐use. One of the main reasons for the conflict has been the extraction sector's inability to adjust to the existing laws. This paper reports the findings of a study undertaken to assess the environmental and socioeconomic impacts of quarry mining in Addis Ababa, Ethiopia, and it prescribes interventions that can assist in mitigating the negative impacts of mining. Marked operational, environmental, and socioeconomic impacts have occurred as a result of cobblestone quarrying in Addis Ababa. Improvements in the mitigation of these impacts can be achieved if quarrying operations are planned prior to commencement; resource‐efficient and sustainable mining techniques are employed; stakeholder participation is enhanced; the government provides institutional, organizational, and technical support to the operators; regulations are improved and regulatory implementations receive strict follow‐up; and the provision of the Ethiopian constitution's regarding “rights to development” is respected.
