To obtain those fuels and minerals which cannot be supplied from intra-CMEA sources, the European CMEA countries have resorted to compensation agreements, long-term supply agreements, and joint venture with the developing countries. Examples of these are given. In the future the European CMEA countries will need to rely increasingly on the developing countries for supplies of raw materials. The reasons for this are examined and new forms of East-South co-operation aré explored.
Pour obtenir ceux des carburants et des mineraux qui ne peuvent pas leur être livrés en provenance de fournisseurs internes du Conseil d'assistance d'économique mutuelle (CAEM), les pays européens du CAEM ont fait appel à des ententes de compensation, à des ententes de livraison à long terme et à des operations conjointes avec des pays en voie de développement. Des exemples sont donnés. Les pays européens de CAEM seront amenés, dans les années à venir, à dependre de plus en plus des pays en voie de développement pour les fournitures en maitières premieres. Les raisons correspondantes sont passées en revue et des formules nouvelles de cooperation est-sud sont explorées.
Para abastecerse de combustible s y minerales que no pueden ser suministros de fuentes de los países del Consejo de Asistencia Económica Mutua (CAEM), los países europeos de CAEM estan utilizando acuerdos de compensación, contratos a largo plazo e inversiones conjuntas con los países en desarrollo. En este artículo se dan ejemplos de estos contratos. En el futuro los países europeos de CAEM dependerán en el suministro de recursos naturales por los países en desarrollo. Se examinan las razones para esta creciente dependencia y se exploran nuevas formas de cooperación Este-Sur.  相似文献

During the next 20 years, coal will have a growing importance both in absolute and relative terms. In the non-OPEC developing countries, coal consumption will double by the year 2000. Coal, however, must be obtained, transported, burned and the residue ash disposed of to be of economic benefit. This paper using current Japanese experience examines some of the problems involved in obtaining and using coal for electric power generation and compares the costs of its use with other fuels.
Il y aura dans les 20 ans a venir une importance accrue du charbon en termes relatifs et absolus. Les pays n'appartenant pas a L'OPEP verront leur consommation de charbon passer du simple au double d'ici l'an 2000. Mais pour avoir une valeur économique, le charbon devra être produit, transporté et brulé, et il se posera en outre un problème d'évacuation des cendres résiduelles. Ce mémoire qui a pour base l'expérience actuelle du Japon fait l'examen de quelques problèmes liés à la production et à l'utilisation du charbon dans le cadre de la production d'énergie électrique. Il compare les coûts d'utilisation de celui-ci et de carburants divers.
Durante los próximos 20 años, el carbón tendrá importancia creciente tanto en términos absolutos como relativos. En los países en desarrollo no miembros de OPEP, el consumo de carbón doblará para el año 2000. Teniendo en consideración la experiencia del Japón, este articulo examina algunos de los problemas en la obtención y uso del carbón en plantas de generación eléctrica y compara con otros combustibles alternativos.  相似文献

This article examines the extent to which selected non-fuel minerals-exporting developing countries can rely on their traditional source of hard-currency earnings to promote future economic growth and to facilitate payments for interest and amortization of accumulated debt. The countries (and minerals) under consideration are: Chile (copper), Bolivia (tin) and Jamaica (bauxite). Incorporated into the study are sets of alternative assumptions regarding global demand for these minerals to the end of the century, market shares, mineral prices, external debt levels and interest rates. More specifically, the study examines the likely ranges of future export revenues of these countries from these minerals in the years 1990 and 2000, and the role that these future export revenues may play in servicing external debt.  相似文献

After several years of experimentation and demonstration, photovoltaic (PV) power is now firmly established for certain applications where reliable power is required in remote locations. The technology has recently matured to the point where PV is now an appropriate, cost-effective technology for village use. This paper reviews experience and presents economic comparisons between photovoltaic and conventional power systems. It is concluded that PV is cost-effective for individual home lighting and small loads such as radios, when compared with kerosene lamps and batteries. For mutiple uses PV is cost-effective compared with diesel generators for daily electricity demands up to around 20 kWh, depending on local conditions.  相似文献

This paper reviews relevant literature on the sustainability indicators theoretically proposed and practically applied by scholars over the past 15 years. Although progress is being made in the development and critical analysis of sustainability indicators, in many cases existing or proposed indicators are not the most sensitive or useful measures in developing countries. Indicator selection needs to meet the following criteria: relative availability of data representing the indicators, sensitivity to stresses on the system, existence of threshold values and guidelines, predictivity, integratability and known response to disturbances, anthropogenic stresses, and changes over time. Based on these criteria, this paper proposes a set of operational indicators for measuring agricultural sustainability in developing countries. These indicators include ecological indicators involving amounts of fertilizers and pesticides used, irrigation water used, soil nutrient content, depth to the groundwater table, water use efficiency, quality of groundwater for irrigation, and nitrate content of both groundwater and crops. Economic indicators include crop productivity, net farm income, benefit–cost ratio of production, and per capita food grain production. Social indicators encompass food self-sufficiency, equality in food and income distribution among farmers, access to resources and support services, and farmers knowledge and awareness of resource conservation. This article suggests that the selection of indicators representing each aspect of sustainability should be prioritized according to spatial and temporal characteristics under consideration.  相似文献

Over the next decade the management of water quality will be one of the outstanding issues relating to the protection and conservation of the national stock of water. In the past, particularly in countries well-endowed with water resources, this has been considered to be a relatively negligible problem. However, the rapid growth of population in major urban centres, industrialization and the heavy dependence on chemical products in the agricultural sector are leading to a serious deterioration of water quality.
This paper reviews the nature of the pollution issue, the institutional requirements to deal with the problem in an effective and comprehensive manner and the near-term actions which governments should take to protect their existing water resources.  相似文献

The industrial harzardous waste problem is going to be explosive in developing countries as they industrialize further. This paper examines the hazardous waste problem, highlights some toxic waste types, and provides a list of industries that generate most of those wastes. Technological, economic and institutional measures that could be combined to mitigate the hazardous waste problem in developing countries are described, and recommendations for dealing with the problem are presented.  相似文献

Multiobjective assessments of water resource projects are useful for widening the range of impacts that are considered during the process of project planning and selection. Some of the principles and problems associated with multiobjective analyses are reviewed, as are several relatively simple information display techniques and approaches found applicable to conditions in many developing countries. These techniques can be used where data and technical expertise are limited, and where it is not possible to identify and quantify all economic, environmental or social objectives and their trade-offs during the search for the best compromise decision.  相似文献

This paper presents a decision support framework for environmental planning in developing countries. The interest in protecting the natural environment from pollution gained increased importance in the 1990s with a push by world communities for sustainable development. Developing countries as well as the industrialized nations are expected to cut down on pollution and control the use of non-renewable natural resources. Although the concept of sustainable development sounds plausible, it is difficult to implement in many countries due to their conflicting goals. The world-wide targets on emissions, use of fossil fuels, reduction in water and atmospheric pollution require the participation of every nation. These goals are not easily achievable by some of the poorer developing countries partly because of their economic dependence on natural resources and partly because of their inability to afford more modern and efficient technologies. Thus, environmental planning goals are often in conflict with the development,social and economic needs of a country. In this paper, we develop a decision support framework that utilizes multicriteria and optimization models to address environmental planning problems. This framework is based on identifying the priorities of conflicting goals by working through and reducing the conflicts. A strategic planning framework is introduced into the decision support system since national planning is a strategic issue and these goals can only be achieved by adopting a systemic view.  相似文献

Significant distinctions that exist between crude oil and natural gas compel that separate terms for gas be included in petroleum agreements. Fiscal terms, production shares and cost recovery are, like oil, important economic considerations in gas agreements. However, unlike oil agreements, other economic terms will also need to receive attention because gas agreements need to give explicit recognition to the process for commercializing the gas discovery.  相似文献

Sources of Deforestation in Tropical Developing Countries   总被引:8,自引:0,他引:8  
/ Key causes of tropical deforestation are investigated using cross-sectional data for 90 developing countries for the period 1981-1990. Regression results reveal that deforestation is associated with both development and scarcity. Deforestation accelerates with expanding infrastructure, trade, debt, investment in the human capital base, and resource-based economic expansion. On the other hand, absolute and relative scarcities-manifested by growing population pressures, food and land shortages, fuelwood dependency, and inequalities in access to land-are also key factors explaining forest loss. Thus, results point to a fundamental environmental conundrum: Development is required if countries are to alleviate scarcity-driven forms of forest exploitation but is itself a major cause of deforestation. Can countries balance development goals with forest protection? Setting aside the issue of its practical realization, the paper concludes that forest sustainable development cannot be achieved by implementing simple technical improvements in land-use practices alone. Securing the foundations for the sustainability of the forest base will require that countries address the underlying social processes driving tropical forest loss as well.KEY WORDS: Tropical deforestation; Developing countries; Rural land-use practices; Development; Scarcity.  相似文献

This paper summarizes the subject matter covered at the United Nations Interregional Workshop on the Utilization of Subsurface Space convened in Stockholm, Sweden, 24–29 October 1982. The utilization of subsurface space has largely been confined to developed countries so far, and the purpose of the meeting was to focus attention upon its potential use in developing countries. Participants at the Workshop discussed the utilization of subsurface space in relation to the underground storage of food and commodities, water, petroleum and gas, and also energy production and utilization. Additional topics included transportation systems and public utilities. The implementation of such projects is discussed with respect to technology and technology transfer and to the economics of subsurface development. As capital, in particular, is a limited resource in developing countries, attention was devoted to the financing of such undertakings. The paper concludes with a brief discussion of the conclusions reached with specific attention to the possible role of United Nations organizations in this increasingly important area. Cet article résume le sujet traité par le Groupe de travail interrégional des Nations Unies sur l'utilisation de l'espace souterrain qui s'est tenu à Stockholm, en Suède, du 24 au 29 octobre 1982. Ce n'est que dans les pays industriels qu'on a jusqu'à présent largement utilisé l'espace souterrain et le but de ce Groupe de travail a été d'attirer l'attention sur le potentiel qu'il représente dans les pays en développement. Les participants ont discuté de l'utilisation de l'espace souterrain dans le cadre du stockage d'aliments et de biens de consommation, de l'eau, du petrole et du gaz, et aussi de la production et l'utilisation de l'énergie. Ils ont également discuté d'autres sujets, tels que les transports souterrains et l'enfouissement des structures industrielles. De plus, l'article traite de la mise en oeuvre de ces projets en ce qui concerne leur technologie et les transferts de technologie ainsi que des aspects économiques de la mise en valeur de l'espace souterrain. Les ressources financières étant, en particulier, limitées dans les pays en développement, le Groupe de travail s'est attaché au mode de financement de telles entreprises. L'article se termine par une brève discussion des conclusions auxquelles sont parvenus les participants en étudiant le rôle possible des organismes des Nations Unies dans ce domaine dont l'importance s'accroît. Este articulo resume el tema tratado en el Seminario Interregional de las Naciones Unidas sobre la utilización del Espacio en Subsuelo que tuvo lugar en Estocolmo, Suecia, del 24 al 29 de octubre de 1982. El espacio en subsuelo ha sido mayormente utilizado sólo por los países en desarrollo por lo cual el propósito de la reunión fue enfocado al caso de los países en desarrollo. Los participantes en la reunión discutieron la utilización del espacio en subsuelo con relación al almacenamiento de alimentos y otros bienes, agua, petróleo y gas y tambien en relación con la producción y utilización de energía. Tópicos adicionales incluyeron los sistemas de transporte y servicio público. La ejécución de tales proyectos se discuten con respecto a la tecnología del desarrollo del subsuelo. Debido a que el capital es la particular en recurso limitado en los países en desarrollo, se dió atención al financiamiento de tales proyectos. El artículo termina con una discusión breve de las conclusiones de la reunión, en especial, aquellos que se refieron al posible rol de las organizaciones de las Naciones Unidas en este área de importancia creciente.  相似文献

The uncertain supply and increasing cost of petroleum products since 1973 has spurred on the development of alternative forms of energy. Natural gas is a major source of energy in over 50 developing countries. In these countries natural gas has many uses as a substitute for other fuels or as a feedstock. This paper discusses the economic concept for pricing of natural gas, in particular marginal costs, and estimates the economic cost of natural gas in developing countries under a wide range of conditions. The marginal cost of natural gas estimated for these countries is far below the border price of competing fuels. Because natural gas is in its early days of development, gas supply costs are not expected to rise in these countries within the next two decades as already proven reserves are tapped.  相似文献

Adaptation to Climate Change in Developing Countries   总被引:2,自引:0,他引:2  
Adaptation to climate change is given increasing international attention as the confidence in climate change projections is getting higher. Developing countries have specific needs for adaptation due to high vulnerabilities, and they will in this way carry a great part of the global costs of climate change although the rising atmospheric greenhouse gas concentrations are mainly the responsibility of industrialized countries. This article provides a status of climate change adaptation in developing countries. An overview of observed and projected climate change is given, and recent literature on impacts, vulnerability, and adaptation are reviewed, including the emerging focus on mainstreaming of climate change and adaptation in development plans and programs. The article also serves as an introduction to the seven research articles of this special issue on climate change adaptation in developing countries. It is concluded that although many useful steps have been taken in the direction of ensuring adequate adaptation in developing countries, much work still remains to fully understand the drivers of past adaptation efforts, the need for future adaptation, and how to mainstream climate into general development policies.  相似文献

/ Achieving successful and well-integrated environmental management depends on principled and orderly assignment of responsibilities within and between public sector organizations. Guidelines for making these assignments can be found by considering different modes of public response in light of a framework based on some distinguishable patterns in the complexity they exhibit. The basic dimensions of environmental problems can be used to identify these patterns. Two examples from current environmental problems in Taiwan are given, illustrating how this framework can be put to use.  相似文献
