[en] Because the world population is likely to double over the next century, with most of the increase being in the developing countries, the stresses caused by a lack of energy will increase unless tackled with determination. A truly global effort led by the industrialized countries is called for. The WEC advocates specific actions to be taken. It takes decades for energy projects to build up the required critical mass to impact on a global scale. Unless action is taken now to accelerate these processes, the future sustainability of energy production and use runs the risk of being badly compromised, to the disadvantage of all

[en] The question is posed as to whether high technology in nuclear medicine might lead to the nuclear medicine practitioner possibly finishing up working for the machine rather than the improvement of health care in its widest sense. A brief examination of some pros and cons of high technology nuclear medicine is given. (U.K.)

[en] This work is related to the world economic outlook for the 1990S. It is discussed here: the new global economy, financial relations, output and income trades in industrial countries structure of imports and exports of developing countries, international policy issues, exchange rates, debt crisis, international trade and international economic environment.

[en] Based on the review of the basic design of the sectoral crediting mechanism (SCM) – a promising option for developing countries’ emission reduction commitments – this paper analyzes five important practical issues for China to solve before participating in SCM, which include (1) difficulties in determining a crediting baseline (2) the unsolved over-supply problem in the carbon market (3) the very likely “carbon credits falling short of mitigation costs” problem (4) the immature market-oriented price system jeopardizing the success of motivation incentives and (5) inadequate capacity building. Corresponding suggestions or compromise solutions are given after a discussion of each issue. It is also recommended that in order to witness SCM come into being, researchers and negotiators should endeavor to solve the practical issues that SCM meets now, bearing in mind the balance of interests of both developing and developed countries. Finally we believe that SCM’s political barriers can be overcome when technical, economic institutional and capacity problems are solved. - Highlights: ► Latest developments in Sectoral Crediting Mechanism design have been reviewed. ► Ten years would be an ideal duration to adjust sectoral crediting baseline in China. ► Specific sectors could be selected to solve the carbon credits over-supply problem. ► SCM credits may come short of the mitigation costs, claiming a rising carbon price. ► Pricing system in China’s electricity sector makes it not a good candidate for SCM.

[en] Over the past 35 years, considerable experience has been gained in decommissioning many types of nuclear facilities. By the turn of the century, more than 60 nuclear power plants and 250 research reactors around the world will become likely candidates for decommissioning. Several factors influence the choice of decommissioning strategy in a country and consequently, the decommissioning cost estimates performed are difficult to compare. International efforts to harmonize the various estimates are essential. The IAEA introduced the concept of various cost elements or components, a suggested methodology and it has also undertaken, in its 1991-92 programme, some specific studies on a common methodology for decommissioning cost estimation. 2 figs, 1 map, 2 tabs

[en] This article determines the conditions under which the Southern countries should act together, or separately, while negotiating with the North about climate change policy and about the conditions for future Southern engagement. The paper models the international negotiations with complete and with asymmetric information in a dynamic framework. Results show that, depending on their characteristics, the different players can obtain benefits delaying the moment of the agreement

[en] Due to the fact that human activities and most sustainability issues are closely related to energy use, the energy system is a sound framework for providing lead indicators for sustainable development. Common energy-economic models enable the estimation of future states of the energy system. An energy system-based lead indicator set can be used to develop consistent and coherent future indicator estimates and to track sustainability, a clear advantage over existing sets. In developed countries, the sustainability discussion is focused on environmental topics, while in developing countries the issues of poverty and equity are equally important. Consequently, for measuring sustainable development in a developing country, the inclusion of a poverty indicator in a set of lead indicators is essential. By correlation and descriptive analysis, it is shown that reliable energy-based indicators of poverty can be created. Although no one-dimensional indicator is a comprehensive measure of poverty, the explanatory power of energy poverty indicators is comparable to that of other poverty indicators. Thus, the use of energy indicators is not restricted to environmental and economic issues but is also relevant for social issues

[en] Drinking water in developed countries is usually treated by the water-purification system, while in developing countries untreated natural water such as well water, river water, rain water, or pond water are used. On the other hand, many kinds of mineral water bottled in plastic containers are sold as drinking water with or without gas in urban areas in many countries. Seawater under hundreds meters from the surface is also bottled and sold as drinking water with advertising good mineral balance. Various element concentrations in water samples for drinking were analyzed, and then it was considered the effects of elements on human health. (author)

[en] A two-fold strategy appears necessary to ensure that the resource needs of the developed and developing nations are met. First, recycle and substitution must be encouraged in those instances where they do find application. Although these measures have limited applicability, they may be of vital importance in those instances where they do apply; in any event, they buy time. Second, practical and economical technologies must be developed to exploit the lower-grade and marginal ores and the oftentimes abundant but highly refractory ores, as well as to greatly increase the recovery of secondary elements present in the ores - elements whose form and amounts in the ores make them economically unrecoverable by themselves, but which are economically recoverable as by-products. It is often the case that if these elements are not recovered during the initial mining and milling operations, they are rendered unrecoverable, in a practical sense, forever. Furthermore, they may even become environmental pollutants. Specific examples of recovery from refractory ores, by-product recovery, and recycle are given. Also, some suggestions of substitutes for important resources are tabulated
