As in many fen land regions in East Germany, long-standing intensive arable farming—enabled by reclamation—has caused soil deterioration and high water runoff in the Schraden region. The more than ten years of economic and political transformation that followed the breakdown of the socialist regime has worsened the situation and even added new problems. The visible consequences are droughts in the summer, waterlogged plots in the spring, and worn-down water management facilities that operate in an uncoordinated or even unauthorized way. Given the local public-good character of some features of the fen land, the common-pool character of the ecosystems intermittently scarce resource water, and the conflicting interests of regional stakeholders, it is argued that the reallocation of property rights over reclamation systems, together with ineffective coordination mechanisms, have caused the physical and institutional failure of the water management system and so impeded appropriate land use. Note: This version was published online in June 2005 with the cover date of August 2004.  相似文献

The authors consider consumption of copper in the UK using data from 1920 to 1970. They draw up an overall balance sheet which, it is hoped, provides a firm foundation on which to base the total availability of copper and against which could be balanced the scrap which was recycled.  相似文献

The basic objective of this paper is to present a policy assessment of the Saskatchewan Uranium Royalty (SUR). This scheme, as enacted on 1 August 1976, was designed to be an integral part of the province's rent appropriation and economic development strategy. Before the tax regime is addressed directly an overview is given of the resource policy environment within which the impost was developed.  相似文献

This paper explores the background of a proposed revision to the Mineral Resources Law of China, why and how the law was amended in the past, its salient features and objectives. Of equal importance is an analysis of how this national law, with its attendant regulations and policies, formed the basis for the growth and continued development of China's small-scale mining industry. The Xiaoqingling Gold Mountain case study is shown to justify the necessity and feasibility for formalizing and consolidating small-scale mines in China, and to some extent, the success of the nation-wide ASM resource consolidation policy at a local level.  相似文献

In what circumstances do organizations react to changes in their operating environment by adopting proportionate policy responses? And drawing on institutional theory, what expectations can we formulate in relation to the proportionality of policy responses to climate change? These two research questions frame this article, which seeks to make new connections between the emerging perspective of proportionality in policy-making and existing institutional theories. We find that institutional theories are well suited to formulating expectations concerning the (dis)proportionality of policy responses, but their explanatory power can be further improved by taking the characteristics of specific climate policy problems into account. While there are many different problems nested in the ‘meta’ problem of climate change, we find that most of them have characteristics which suggest that policy under-reactions are more, not less likely. Amongst institutional theories, rational choice institutionalism provides the clearest expectation that proportionate policy responses are unlikely. Policy entrepreneurship is identified as one obvious way in which to stimulate proportionate policy responses, through fostering new ways of thinking within organizations.  相似文献

Change has been the leitmotif of Mongolia in recent years as the country rides on the back of a mining boom, but enormous upheavals tear apart Mongolian economic, political and social fabrics. Yet, Mongolian imagination continues to be imbued with the idea of nomadic herders, the quintessential pasture and rangeland dwellers of the steppes. The conflicting visions raise the question: “How is the livelihood of Mongolia’s nomadic herders responding to the diverse changes ushered in by the post-socialist economic reforms?” This paper investigates this question in the context of the growing artisanal and small-scale mining, which is described as informal mining, and argues that the Mongolian nomads are continually (re)adjusting their livelihoods through informal mining to cope with the variety of transitions triggered off by processes put in place by state policies. It argues that the nomadic herders are not only responding to climate change or poverty, but are also stepping up to seek a share of the mineral resource wealth that the state is promising to the international investors. The aim of the paper is to offer an alternative interpretation of the commodity rush by erstwhile rural-based nomadic herders of Mongolia, and to link their involvement in informal mining with global debates of political economy.  相似文献

Developing a more widespread diffusion of sustainable agricultural practices as part of progressing rural sustainable development is being hampered by different modes of environmental social thought. This introduction to this special issue on ‘Reconstituting of nature through rural development practices’ argues for a realignment of social theory and empirical practice in considering the real potentiality of alternative and emergent rural development cases. The social science of agro-ecology is introduced as an initial framework within which to assess such alternatives and emerging tendencies. Copyright © 2001 John Wiley & Sons, Ltd.  相似文献

This paper reviews a series of strategies for improving environmental performance in the small-scale gold mining industry. Although conditions vary regionally, few regulations and policies exist specifically for small-scale gold mining activity. Furthermore, because environmental awareness is low in most developing countries, sites typically feature rudimentary technologies and poor management practices. A combination of policy-, managerial- and technology-related initiatives is needed to facilitate environmental improvement in the industry. Following a broad overview of these initiatives, a recommended strategy is put forth for governments keen on improving the environmental conditions of resident small-scale gold mines.  相似文献

Throughout history, mining communities have invariably found themselves striving for a good quality of life and a long‐term future. In the 21st century, problems of maintaining the economic vitality of mining regions are now compounded by concerns about the biophysical integrity of the local environment. In regions of the world where the economic viability of the resource is marginal and achieving a reasonable quality of life is a daily struggle, sustainable mining may seem to be a dubious prospect at best. Yet the twin imperatives of global political forces and burgeoning environmental concerns are requiring industry, governments and other interests to re‐conceptualize the way in which mining takes place in communities. Although mining itself may not be seen as an industry that contributes to the achievement of environmental objectives, it could — with careful planning — be used as a tool to foster a more sustainable and healthier community. This argument is considered in the context of the coal mining region of Santa Catarina, Brazil.  相似文献

Over the last five decades, Malaysia has undergone rapid economic, social and environmental change, a process which is still continuing. The pursuit of socio‐economic progress has been accompanied by an unprecedented rate of change in the natural environment. In parallel to this development, governmental responses have also adapted over time to address emerging environmental situations. This article views the recent history of Malaysia's evolving policy response to development needs and environmental change as consisting of four distinct stages. Despite an impressive array of policy statements and strategies to implement sustainable development, many challenges remain today. A clear articulation of normative principles of sustainable development is of paramount importance, as is the monumental task of policy implementation. The article argues that the trajectory of Malaysia's policy on natural resources and environmental issues bears the characteristics of path‐dependent evolution.  相似文献

An analysis of 179 junior exploration floats, listed on the Australian Securities Exchange (ASX) between July 2001 and June 2006, helped to build a basic understanding of the strategy and business structure of these companies. The “typical” junior explorer raised A$4 million at initial public offering (IPO) to finance a 2-year, mainly greenfields exploration program. The capital raised at IPO entitled its investors to approximately half of the company, with the balance in the hands of the promoters, vendors and/or seed capital investors. Of the A$4 million raised at IPO, it intended to spend approximately two-thirds on exploration, while the remainder was absorbed in corporate overheads and the costs of the IPO. Once these were paid, ongoing corporate overheads averaged approximately 28% of its total operational expenditure. However, given an average total annual expenditure of approximately A$2.6 million, most juniors held insufficient capital reserves to meet operational costs beyond a time frame of 2 years. As at October 2006, 9% of the companies were in the process of mine construction, whereas 6% had made it to producer status. The lead time from listing to production ranged from 1.5 to 53 months, giving a median of 28 months.  相似文献

The old tension between planning and law is revived in current practices of sustainable development. Urban professionals often blame central regulation for frustrating an inventive integration of local initiatives and policies. Against this background, the authors focus on the potential of ‘legal contextualisation’: the challenge of how to improve on regulation in such a way that it guides local practices in a normative sense but simultaneously enables optimal use of local – context bounded – option space. In order to make legal contextualisation researchable, the next four operational avenues of analysis are constructed in this paper: the normative dimension (requiring quality of legal norms); the relational dimension (studying the alignment of norms in different positions, such as the legislation, the court, and social compliance); the temporal dimension (searching the alignment of different moments of legal validation); and the functional dimension (making transparent the different roles that government agencies may take).  相似文献

The importance of global corporate green research and development (R&D) investment is gaining momentum and South Africa is no exception. This paper examines growing economic perceptions that green financial and stock-market systems result in heightened corporate hyperopia and therefore increase long-term and future green investment associated with R&D. It reports on the findings of a survey of 14 South African mining firms listed on the Johannesburg Stock Exchange SRI index. The study found, that, these firms’ market value showed a positive association with Green R&D. It also revealed increased Green R&D activity among large mining firms in the country and that they are highly likely to maintain their level of such investment in the coming years. The study's outcomes thus add to the body of empirical knowledge on firm hyperopia in relation to corporate greening initiatives.  相似文献

For many centuries, emeralds have bejeweled the rich and famous all over the world. Emeralds have also made many millionaires overnight, sometimes by chance, as in some of the cases reported in this study. On the other hand, even though emerald mining has brought some economic benefits, many of these have remained at the top of the production chain. In many cases mining activities have caused a number of negative social and environmental impacts locally. Working conditions in small mines are very poor in general: with bad ventilation, high temperatures, long working hours, lack of safety, informal working contracts and no health or life insurance. Environmental impacts can be significant, such as widespread deforestation, erosion of abandoned mines, and soil and water pollution in streams. The economic and social public benefits can be minimal. Even when taxes on gem mining are relatively low, much of the mining local activity is informal and the high value-added formal activities take place outside the mining regions. This study aims to understand the dynamics of emerald mining and its impact on local development using the concept of clusters. The research analyzes three case studies in Brazil: Campos Verdes/Santa Terezinha (Goias state), Nova Era/Itabira (Minas Gerais state) and Carnaiba/Campo Formoso (Bahia state). Emerald mining regions attract many migrants, increasing the demand for public services (infrastructure, health, education, etc.), but local governments are unable to provide for them because the activity produces little tax revenue. In the end, there is a growing mismatch between demand and supply of public services, leading to a series of social and environmental problems. However, working with the concept of cluster can help to shed light on policies to improve the local benefits of gem mining, by organizing the miners and their supporting organizations to allow investments that bring long term benefits locally.  相似文献

ABSTRACT

In the climate and land use fields, policy mixes are complex in terms of the levels of governance, actors, and roles. They consist of policy instruments that target different actors and address multiple goals across several policy sectors and levels. The analysis of these complex arrangements extends beyond purely technical efficiency criteria, as several sources of tension between instruments may be identified, such as conflicting interests, goals, and approaches to implementation. The proliferation of governance networks complicates the understanding of actors’ interactions, the types of authority influencing the outcomes of policy mixes, and importance of different levels of governance. This article provides a framework to address these analytical challenges, particularly the interconnected networks of policy actors and policy instruments. It draws on polycentric governance literature to analyse how power matters in policy networks. This includes identifying distinct types of power, actors’ position, and variables that explain patterns of conflict, competition, convergence, and divergence in policy choices and outcomes. The framework is applied to the climate and land use policies implemented in the state of Mato Grosso, Brazil. Several methods were used to clarify these variables and to characterise policy mixes being implemented in the region, including social network analysis.  相似文献

Dettinger, Michael, 2011. Climate Change, Atmospheric Rivers, and Floods in California – A Multimodel Analysis of Storm Frequency and Magnitude Changes. Journal of the American Water Resources Association (JAWRA) 47(3):514‐523. DOI: 10.1111/j.1752‐1688.2011.00546.x Abstract: Recent studies have documented the important role that “atmospheric rivers” (ARs) of concentrated near‐surface water vapor above the Pacific Ocean play in the storms and floods in California, Oregon, and Washington. By delivering large masses of warm, moist air (sometimes directly from the Tropics), ARs establish conditions for the kinds of high snowlines and copious orographic rainfall that have caused the largest historical storms. In many California rivers, essentially all major historical floods have been associated with AR storms. As an example of the kinds of storm changes that may influence future flood frequencies, the occurrence of such storms in historical observations and in a 7‐model ensemble of historical‐climate and projected future climate simulations is evaluated. Under an A2 greenhouse‐gas emissions scenario (with emissions accelerating throughout the 21st Century), average AR statistics do not change much in most climate models; however, extremes change notably. Years with many AR episodes increase, ARs with higher‐than‐historical water‐vapor transport rates increase, and AR storm‐temperatures increase. Furthermore, the peak season within which most ARs occur is commonly projected to lengthen, extending the flood‐hazard season. All of these tendencies could increase opportunities for both more frequent and more severe floods in California under projected climate changes.  相似文献

ABSTRACT: Recent occurrences of heavy rainfall in New Orleans, Louisiana, have led to speculation that the local heavy rainfall regime has changed. To objectively determine the validity of these speculations, changing magnitudes of storm rainfall were investigated through an examination of the annual maximum storm series from 1871 to 1991 at the New Federal site. Although a long-term trend was not found, the Wilcoxon test indicated that magnitudes during the last 14 years (from 1978–1991) differed significantly from the rest of the series.  相似文献

Despite several recent UK initiatives to promote renewable energy development at the local level, little research has been carried out to investigate public beliefs about aspects of local renewable energy development. This research attempted to address this gap. Empirical data were collected at the Awel Aman Tawe development in South Wales immediately before and after a public participation process. The results indicate that support for specific aspects of local energy development (partnership with local communities, local use of generated energy and profits put back into the local community) was consistently high across time, with support for local ownership at a slightly lower level, yet still high. Secondly, socio-demographical analyses indicated that personal factors such as respondents' age, gender and employment status were important in shaping several of these beliefs. Since UK renewable energy development has often been controversial and subject to delay, results suggest that the adoption of a locally embedded development approach by public and private sector stakeholders will be strongly supported by local people. The implications of the results are discussed in relation to existing industry best practice guidelines and recent policy initiatives.  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
