China has been trying to improve the safety and environmental performances of small coal mines (SCMs) in 2000s through measures of trusteeship and consolidation. The question whether such policy and practice can sustain small scale mining is interesting academically and important practically for China and the world. This paper finds that the Chinese SCM policy has been switched from encouragement to restriction for legal SCMs and from privatization to nationalization in some provinces in the past 10 years. Legal SCMs face pressure to be expanded continuously and to be absorbed or consolidated by large coal mines, which often are state owned. Unexpectedly, financial resources may not be a big constraint nowadays due to availability of private equity investment resources. The paper argues that both the trusteeship and consolidation approaches may only be able to sustain SCMs in the short run. A more sustainable measure is to establish a stable, transparent and inclusive legal and fiscal framework. This paper concludes that those trusteeship approaches may be applicable to restructuring small scale mines in other countries; however, the consolidation practice in China's is unique and thus may not be applicable to others.  相似文献

A growing number of people are entering the artisanal and small‐scale mining (ASM) sector worldwide. In Madagascar, millions of individuals depend on this informal activity. Through a case study in the Alaotra‐Mangoro region of Madagascar, our research aimed to understand the “bottom‐up” dynamics and ripple effects of the sector, by looking at the realities for rural communities where inhabitants are both directly and indirectly affected by ASM. We were interested in community members' and miners' perceptions of the socio‐economic and environmental impacts of ASM, and in identifying the factors attracting people living in one of the country's agricultural hubs to this activity. Our results show a wide diversity of push and pull factors leading people to enter the sector. Although many positive impacts of ASM exist for miners and communities within the vicinity of mines, most miner participants considered themselves worse off since starting to mine, highlighting the high risk and low probability of return of ASM. ASM's potential for local and national development will remain squandered if its negative impacts continue to go unmanaged. Accounting for local contexts and the ripple effects of ASM will be crucial in achieving safety and security for miners, and to tap into the benefits it may offer communities while minimising environmental damage.  相似文献

China is the world's largest energy consumer, and coal accounts for a higher proportion of the country's total energy consumption, yet during its 12th five-year plan (2011–2015), the coal share among total energy consumption significantly decreased. Previous studies exploring energy performance typically used energy consumption as an input, but this lacks the analytical capacity for the structure of energy consumption. Thus, this study splits energy input into two different inputs, coal consumption and non-coal energy consumption, and based on their differences with other variables, uses the hybrid dynamic data envelopment analysis model to assess the energy performance of China's provincial industrial sector during the period 2011 to 2015. We then compare coal consumption's and non-coal consumption's rooms for improvement and conclude that provinces in eastern and central China should reduce the amount of coal consumption, thereby improving energy performance. Conversely, provinces in the western region should target a balance between energy utilization efficiency and coal consumption.  相似文献

Compositional changes to air quality from coal mining are not only the most visible impact from these activities on the environment, they can also immediately affect the health of mine professionals and adjoining populations. The presence of gases and suspended solids emitted by mining activities affects the human respiratory system and decreases production in mines. This article summarizes a case study of several Northern Coalfields Limited (NCL) coal mines with an emphasis on particulate matter (PM) to report the status of air quality connected to coal production and overburden removal. The concentrations of sulfur dioxide (SO2), nitrogen oxides (NOx), and suspended particulate matter (SPM) reported in the literature are also summarized in table form to allow comparisons to the permissible standards set by the Indian Central Pollution Control Board (CPCB) and other standards used around the world. An up‐to‐date status of air quality at coal mines is compared for mines located in different parts of India. Subsequently, all coal mines were divided into different classes in regard to the severity of their emissions. These classes are, in increasing order of severity, green, yellow, red, and black. SPM measurements were tabulated in regard to concentration and composition. Our article concludes with the recommendation that an environmental impact assessment (EIA) to be conducted to better characterize changes in the environment from mining emissions to develop integrated mitigation measures and to identify additional parameters to define air quality at mines.  相似文献

Coal is the major primary energy which fuels the economic growth in China. The Soviet-style institution of the coal sector was adopted after the People’s Republic was founded in 1949. But since the end of 1970s there have been major changes: the market mechanism was introduced to the coal sector and the Major State Coal mines were transferred from central to local governments. This paper explains these market-oriented and decentralized reforms and explores their implications for the power sector, now the largest single consumer of coal. The argument of this paper is that the market-oriented and decentralized reforms in the coal sector were influenced by the changes in state energy investment priority as well as the relationship between the central and local governments in the context of broader reforms within China’s economy. However, these market-oriented and decentralized reforms have not equally influenced the power sector. Even though initial coal sector reform spurred power generation, the subsequent fragmented reforms raise concern about electricity shortages.  相似文献

Mineral development has contributed greatly to China's economic and social development. Many challenges remain, however, including environmental pollution and resource waste in practice, as well as a dearth of systematic theoretical research. The goal of this study is to analyze the economic and social effects of various mineral developments in China from diversified perspectives, so as to provide the basis for the formulation of China's mineral development policy. The input–output effects, industrial linkage effects and income distribution effects of different mining industries are quantitatively analyzed by adopting basic hypotheses of input–output economics, industrial linkage model and income distribution antitheses based on the latest available official data from China Statistical Yearbook from 2004 to 2010 and the 2007 Input–Output Table of China. The empirical results obtained in this study indicate that all mineral development industries, especially coal mining and washing, and petroleum and natural gas extraction industries, have given a strong impetus to the increase of China's fixed asset investment and GDP. Moreover, they have provided a large number of jobs, thereby alleviating ongoing employment pressure, and they have also played a positive role in promoting China's technology investment. The analysis of industrial linkages demonstrates that mining industries are basic to the national economy and produce a significant impetus to its downstream industries, but create weak pull effects in terms of national economic development. From the perspective of income distribution, mining industries play an important role in increasing China's fiscal revenue and per capital income. Hence, China's mineral development policy should (1) encourage additional investment in technology for exploration and development to insure sufficient supply and expand the input effects; (2) attract additional talent to work in remote regions; (3) optimize the industrial structure and promote the industrial transformation in resource regions; (4) adjust the interest distribution between the central and local governments to enable the local regions to become more self-sufficient; and (5) enhance the legal environment so that companies can more readily undertake their social responsibilities voluntarily.  相似文献

改革开放以来,我国的对外经济贸易有了显著的发展,外商直接投资和进出口的快速增长有效地推动了经济的快速发展。然而在经济发展的同时,我国碳排放水平日益提高,已成为全球最大排放国。为了更好地管控碳排放,研究外商直接投资(FDI),对外贸易与碳排放的关系具有重要意义。本文通过对我国1995—2011年29个省(市、自治区)的FDI、对外贸易对碳排放的动态效应分析发现,FDI与进出口水平的提升均有利于降低我国碳排放的水平,“污染天堂”假说在我国并未得到证实。同时,本文验证了“环境库兹涅茨曲线”在我国的存在,证实了我国的碳排放水平与人均GDP存在倒“U”型关系。  相似文献

This article analyses the question: do attitudes towards risk influence participation in small‐scale gold mining, a hazardous activity that generates uncertain income? This question is examined by measuring and comparing the risk attitudes of gold miners and non‐mining community members in the rainforest of Suriname, South America. The author presents a multivariate model to predict the duration of work in mining areas as a function of risk tolerance, age, education, and household demographics. The results suggest that a greater tolerance to risk increases the duration of a person's mining career. However, attitudes explain only a fraction of the variation in occupational choices. Qualitative data suggest that these choices are primarily shaped by local barriers to human capital development and by national economic volatility. Given their marginal position in society and the multitude of mining risk mitigation strategies, it is questionable whether gold mining exposes Suriname forest peoples to greater risks than other subsistence alternatives. The author argues that sensitivity to local historical and cultural conditions would improve the efficiency of policies aimed at developing a more sustainable mining industry. By zooming in on the daily lives of miners, anthropology can complement macro‐scale analyses and contribute to policy interventions in the small‐scale mining sector.  相似文献

As is the case in many other countries around the world, India's main source of electricity is coal‐fired power plants. In addition to providing energy, the burning of coal also results in large amounts of coal combustion products (CCP), the incombustible material, such as fly ash, left after the coal is burned. These materials are produced in large volume, and if they are not managed or utilized properly, they can pose a danger to the environment. This article discusses the uses of CCP, with a special emphasis on fly ash, and the role that it is currently playing and can continue to play as a mine filler for India's depleted opencast and underground coal mines.  相似文献

China is the second largest emitter of greenhouse gases (GHG) in the world, with potentially about two thirds of total Certified Emission Reductions (CERs) for Asia on the world carbon market (). Since 68% of its primary energy is from coal, China's average energy intensity is 7.5 times higher than the EU and 4.3 times higher than the US (EU, 2003 The European Union on-line. (2003). (http://europa.eu.int/index_ns_en.htm accessed Oct 2003  [Google Scholar]). Therefore, introducing advanced clean technologies and management to China represents opportunities for Annex I countries to obtain low-cost CERs through CDM projects, and access to one of the largest potential energy conservation markets in the world.

CDM can provide a win-win solution for both China and Annex I countries, and the Chinese government considers that the introduction of CDM projects can bring advanced energy technologies and foreign investment to China, thereby helping China's sustainable economy and generating CERs. As energy efficiency is generally low and carbon intensity is high in both China's energy supply and demand sectors, numerous options exist for cost-effective energy conservation and GHG mitigation with CDM.

This paper reviews current Chinese policies and administrative and institutional settings for CDM cooperation, and discusses existing policy, institutional and other barriers in the energy market by drawing on observations and experience from previous initiatives such as Cleaner Production and energy efficiency. Some options to remove these barriers are addressed. In order to make CDM projects feasible, China's government needs to promote awareness, streamline administrative systems, and be more active in building a competitive edge in the world carbon market.  相似文献

Some of China's most prominent environmental problems are related to energy The air pollution of the cities and industrial centers is caused by the inefficient combustion of coal. Deforestation is due to a certain extent to the procurement of firewood. Further problems are caused by the ash and slag from coal combustion and the oil pollution of the sea. While most of China's air is still clean, pollution levels in the cities surpass by far those of German industrial towns, and the health effects are becoming apparent The problem of deforestation must be considered still more serious because it affects whole regions. Short-term effective solutions to the problems presented are not available  相似文献

The control of water pollution in China's South-North Water Transfer Project (SNWTP) is examined through the lens of promotion tournaments as Chinese governmentality to offer a special perspective on China's hydro-politics and Chinese manners of water pollution control. This paper characterizes the existing form of governmentality in the SNWTP, pointing to its problems and potential resolutions. The promotion tournament is a market system with authoritarian control, designed to reconcile the incentives of local officials and the central managers of the SNWTP. This governmentality embodies characteristics of China's authoritarian water management system: centralized personnel control combined with market-oriented promotion competitions. However, a clear conflict between the requirements of ecological modernization and the use of power in China's water management system leads to distorted behaviors among local officials, an important source of problems in China's water management system. Compared to promotion tournaments, payments for ecosystem services or eco-compensation are applications of neoliberal environmentalism that could overcome the shortcomings of tournaments, and become the most critical governmentality for water pollution control in the SNWTP.  相似文献

In recent years, policy mechanisms to support a formalized artisanal and small‐scale mining (ASM) sector in sub‐Saharan Africa have gained increasing currency. Proponents of formalization argue that most social and environmental problems associated with the sector stem from the fact that ASM is predominantly unregulated and operates outside the legal sphere. This paper critically examines recent efforts to formalize artisanal and small‐scale mining in West Africa, drawing upon recent fieldwork carried out in Sierra Leone, Ghana and Mali. In exploring the sector's livelihood dimensions, the analysis suggests that bringing unregulated, informal mining activities into the legal domain remains a considerable challenge. The paper concludes by confirming the urgent need to refocus formalization strategies on the main livelihood challenges and constraints of small‐scale miners themselves, if poverty is to be alleviated and more benefits are to accrue to depressed communities in mineral‐rich regions.  相似文献

This study examined the environmental and social effects of large‐scale mining in Chingola, Zambia. Data was collected through semi‐structured interviews with 164 residents living close to Zambia's largest open pit mine, key informants and desk analysis of secondary data. Quantitative data was analysed using the chi‐square test, one sample T‐test and two sample Z‐proportions test, while qualitative data was analysed using content analysis. Results show that the residents reported being most affected by sulphur dioxide air emissions and noise pollution due to the proximity of the copper smelter and heavy moving machinery to their residences. The residents received domestic water containing rust and copper ore particles from the water utility company which draws raw water from the mine. Although the mine was a source of employment for locals, over 4,000 jobs (representing a 33% decrease) have been lost over a period of 4 years, negatively affecting the local economy. Mine management attributed the job losses to high production costs and mechanization of mining processes. The residents perceived the job losses to have led to crime, alcohol abuse and prostitution among youths as well as a general increase in poverty levels. Analysis of air emissions data from the mine found elevated levels of dust, cadmium, copper and lead pollutants. Key informants from Nchanga Mine reported implementing bioremediation to reduce soil contamination by the heavy metals and recycling SO2 to produce sulphuric acid. The study recommends an increase in social corporate responsibility from the mine management to ensure residents derive more substantive benefits from their proximity to the mine.  相似文献

The obvious paradox within China's environmental politics is the big gap between the central government's policy and its implementation outcomes at local levels. Despite concerns about implementation at the local level, much about the role of central governments in China's local environmental politics is still poorly understood. This article examines how the incentive structure set by the central authorities affects the policy implementation gap at the local level. Drawing on fieldwork and document analysis, this article argues that the incentives set by the central government regarding environmental policy implementation at local levels are perversely structured, meaning that the central government provides much more incentive for local governments' non-implementation or poor implementation of its environmental policies than it provides for full implementation. The central government's failure to encourage—politically, financially, as well as morally—local government officials to appropriately implement environmental policies can partly explain the production of the policy implementation gap at the local level. This implementation gap cannot be overcome by efforts at the local level unless the central government takes significant measures to address the perverse incentive structure embedded in the overall structure of China's local environmental politics.  相似文献

This brief pilot study implements a camera‐based laser scanning system that potentially offers a viable, cost‐effective alternative to traditional terrestrial laser scanning (TLS) and LiDAR equipment. We adapted a low‐cost laser ranging system (SICK LSM111) to acquire area scans of the channel and bed for a temporarily diverted stream. The 5 m × 2 m study area was scanned at a 4 mm point spacing which resulted in a point cloud density of 5,600 points/m2. A local maxima search algorithm was applied to the point cloud and a grain size distribution of the stream bed was extracted. The 84th and 90th percentiles of this distribution, which are commonly used to characterize channel roughness, were 90 mm and 109 mm, respectively. Our example shows the system can resolve both large‐scale geometry (e.g., bed slope and channel width) and small‐scale roughness elements (e.g., grain sizes between about 30 and 255 mm) in an exposed stream channel thereby providing a resolution adequate for the estimation of ecohydraulic roughness parameters such as Manning's n. While more work is necessary to refine our specific field‐deployable system's design, these initial results are promising in particular for those working on a limited or fixed budget. This opens up a realm of laser scanning applications and monitoring strategies for water resources that may not have been possible previously due to cost limitations associated with traditional TLS systems.  相似文献

The Komati Downstream Development Project (KDDP), based upon the Maguga Dam has enabled 6,000 hectares of semi‐arid lowveld, in a region with low and highly variable rainfall to be converted from subsistence to irrigated commercial farming, mainly of sugar cane. This has transformed the Swazi sugar industry from one dominated by a small number of large‐scale commercial estates to one where more than 1,500 previously impoverished small‐scale Swazi farmers have been able to enter the industry by joining farmers’ associations and creating communally managed farms. Recent changes to the EU's Sugar Protocol have undermined the financial viability of the KDDP farms and undermined food security, especially for the poorest, due to the cut in sugar prices. However, some farmers’ associations have opted to keep some of their land as irrigated home gardens, rather than convert all their land to sugar cane. This model has improved food security at a time of low sugar prices and points to a more sustainable way of using water from large scale dams than the conventional model. It is argued that the EU should target support to members of the KDDP who have taken out large‐scale loans to pay for the in‐field infrastructure and encourage all farmers’ associations to adopt the food garden model. This would enable them to continue to benefit from the irrigation through improved production of subsistence crops, whilst they diversify their commercial production into novel markets.  相似文献
