The uranium and nuclear industries in China

This article reviews the available information on the uranium industry and the beginning of nuclear power in China. Few details of China's uranium industry have hitherto been published in the West. The broad conclusions reached are that China is faced with severe energy shortages for the foreseeable future; nuclear power will help to solve this problem but the timing and extent of its contribution are uncertain. The central question of civil nuclear policy is whether or not to use imported technology, although satisfactory development of the uranium industry probably will require foreign assistance. The principle conestraint in this regard is foreign exchange. To help overcome this problem the Chinese are now, for the first time, offering uranium on the international market.     

The relationship between resources and living standards

Available estimates of potentially recoverable world mineral and fuel resources are examined with a view to determining whether everyone likely to be living on earth next century could be raised to the material living standards people in developed countries now have. It is concluded that this goal is impossible. A number of fundamentally important implications follow, especially regarding the inappropriateness of growth strategies in general, goals for Third World development, and the need for ‘de-development’ of developed countries to much more frugal, self-sufficient and cooperative social systems.     

Potentially recoverable resources: How recoverable?

There are a number of factors which are likely to limit the proportion of potentially recoverable resources that will actually be recovered. The most important of these concern the way minerals are distributed within the crust and trends in energy costs associated with mineral production. This article offers a pessimistic view of the prospects for mineral supplies early in the 21st century. The resource situation is even less hopeful when the possibility of extending the material living standards of the developed countries to everyone likely to be living on earth late next century is considered.     

Mineral resources appraisal and policy: Controversies,issues and the future

Political-economic events of the 1970s brought mineral resource appraisal to the focus of national policy. Estimates of and methodologies for mineral resources appraisal were scrutinized, revealing deficiencies in method and data and fostering considerable debate about the credibility of estimates and about preferred methodology. Since credibility can be increased through the acquisition of additional geoscience information, questions regarding methodology have more than one formulation and therefore more than one correct solution, depending upon the expected value of additional information and the conditional losses of relevant policy options. When existing information is meagre and the expected value of information is high, the optimum decision may be to defer all policy options until after the acquisition and analysis of- additional information. Decision theory offers an analytical framework that is sufficiently generalized to provide answers for highly varied circumstances of geoscience and resource information and policy issues. Our ability to perform any such analysis is limited by inaccuracies in both geologists' estimates of undiscovered mineral resources, and in economists' calculations of conditional losses of policy options for each of the relevant states of mineral resources.     

The value of mineral resources: Perspectives and conflicts

The concept of value is central to mineral economics as it is all branches of economics. In the minerals sphere particular problems are posed for a theory of value by, firstly, the non- renewability of mineral resources, secondly the substantial effort that must be made to convert a mineral into a useful product, and finally the perception of minerals, both economically and symbolically, as peculiarly national forms of wealth. Some thoughts are offered on different approaches to mineral resource valuation and on the frequently conflicting principles of exploitation to which these various approaches give rise.     

The hotelling valuation of natural resources: some further results

This paper tests the Hotelling Valuation Principle (HVP) for natural resources using data from oil and gas ‘pure plays’ such as royalty trusts and master limited partnerships. The results support the HVP which specifies that the value of any mineral reserve may be predicted by the market price of the resource, net of extraction costs. Regression results also indicate that a Box-Cox transformation of variables provide a better means of estimating the functional relationship between the value of an exhaustible natural resource and its market price.     

Energy efficiency: The best immediate option for a secure, clean, healthy future

The imperatives for reducing the world's dependence on fossil and nuclear fuels have multiplied manifold in recent years with the advent of worldwide terrorism. These new dangers come in addition to the imperatives of addressing the dire consequences of global warming and devastating pollution that accompany the use of these fossil fuels. Reducing dependence on these unsafe and unreliable energy resources should be a top global priority. Implementation of proven energy efficiency technologies offers the world the fastest, safest, most economic and most environmentally benign way to alleviate these threats. This article outlines available efficiency measures, their economic advantages and means by which they may be and have been implemented. While examples of efficiency applications from both developed and developing countries are given, the article relies heavily on experience with energy efficiency in the United States, where data on efficiency is particularly abundant.     

Project appraisal and planning for overdeveloped countries: I. The costing of nonrenewable resources

In cost-benefit analysis, natural resources, like other factors of production, should be costed as a mixture of marginal social cost of exploiting additional resources and lost marginal social benefit of forgone alternative uses, according to the way in which extra resources are made available to a project. For a nonrenewable resource, changes in future marginal social cost and marginal social benefit are likely to add significantly to the immediate elements of cost, as successively less tractable resource stocks are exploited. Of the several reasons given for ignoring these future costs, the most plausible is that technological advance justifies a heavy discount on the future. However, neither historical nor logical arguments demonstrate the inevitability of efficacious technological advance.     

Building resilience to drought in desertification-prone savannas in Sub-Saharan Africa: The water perspective

Securing sustainable livelihood conditions and reducing the risk of outmigration in savanna ecosystems hosted in the tropical semiarid regions is of fundamental importance for the future of humanity in general. Although precipitation in tropical drylands, or savannas, is generally more significant than one might expect, these regions are subject to considerable rainfall variability which causes frequent periods of water deficiency. This paper addresses the twin problems of “drought and desertification” from a water perspective, focusing on the soil moisture (green water) and plant water uptake deficiencies. It makes a clear distinction between long‐term climate change, meteorological drought, and agricultural droughts and dry spells caused by rainfall variability and land degradation. It then formulates recommendations to better cope with and to build resilience to droughts and dry spells. Coping with desertification requires a new conceptual framework based on green‐blue water resources to identify hydrological opportunities in a sea of constraints. This paper proposes an integrated land/water approach to desertification where ecosystem management supports agricultural development to build social‐ecological resilience to droughts and dry spells. This approach is based on the premise that to combat desertification, focus should shift from reducing trends of land degradation in agricultural systems to water resource management in savannas and to landscape‐wide ecosystem management.     

The whole relationship between environmental variables and firm performance: Competitive advantage and firm resources as mediator variables

The examination of the possible direct link between environmental protection and firm performance in the literature has generally produced mixed results. The present paper contributes to the literature by using the resource-based view as a mediating process in this relationship. The study specifically tests whether or not the resource-based view of the firm mediates the positive relationships of proactive environmental management and improved environmental performance with competitive advantage, which also has consequences for financial performance. We also check the possible link between the adoption of a pioneering approach and good environmental management practices. Our findings support that early investment timing and intensity in environmental issues impact on the adoption of a proactive environmental management, which in turn helps to improve environmental performance. The findings also show that a firm's resources and competitive advantage act as mediator variables for a positive relationship between environmental protection and financial performance. This contribution is original because the present paper develops a comprehensive whole picture of this path process, which has previously only been partially discussed in the literature. In addition, this study clarifies a relevant point in the literature, namely that the effect of environmental protection on firm performance is not direct and can vary depending on the sector considered. Whereas competitive advantage in relation to costs influences financial performance in the IPPC law sector, the relevant influence in the hotel sector comes from competitive advantage through differentiation.     

Change in environmental stability and the use of resources on small islands: The case of Formentera,Balearic Islands,Spain

Since the beginning of the 1960s, mass tourism has been the most important menace to the environmental stability of fragile and vulnerable Mediterranean microinsular systems. The socioeconomic changes introduced by tourism have produced important variations in the use of resources, including land. The result usually has been an increase in the level of artificiality of the territory, particularly in coastal areas. The intensity and frequency of change in the use of resources and the induced changes in the level of artificiality may be used as an estimation of environmental stability. The northern area of Formentera, Balearic islands, Spain, being the most environmentally important area of the island and simultaneously the most threatened by mass tourism development, has been chosen as a study case. Forty types of vegetation and land use have been estimated and mapped in the area. The stability level of each land use type has been estimated, before and after the development of tourism, and the main environmental processes have been identified. An attempt is made to predict some future trends and their variations.
