The changing status of the global environment, in both developed and developing countries, and our perception of these changes since the convening of the United Nations Conference on the Human Environment in Stockholm in 1972 are reviewed. The present as well as potential future environmental issues facing mankind are discussed under three interrelated broad categories: interrelationship between people, resources, environment and development, rational use of natural resources and new patterns of development and lifestyle.  相似文献

Over the past decades, many Asian economies have achieved striking levels of economic growth. This economic growth has been necessary in order to fulfil the material needs and aspirations of growing populations. However, it has also been accompanied by substantial environmental degradation. While the precise interactions between economic growth, economic development and environmental degradation is subject to controversy and a comprehensive assessment of the Asian environment may be required to fully understand this relationship and the present conditions of the environment, it is argued in this paper that the achievement of sustainable economic development and the harmonizing of economic and environmental objectives will not be possible without deliberate policy interventions. Such policies need to incorporate a regional dimension in the form of institution building, in parallel to the concept of regional economic growth. The article focuses on the current problems of environmental and natural resource degradation in Asia, within a possible conceptual framework of impoverishing or unsustainable economic growth, and suggests a set of policies that need to be adopted in order to solve current difficulties.  相似文献

This paper examines the various pressures for state action in respect of land use and environmental management. It then considers the processes through which these pressures are currently being articulated into policies and actions. A brief assessment of the effectiveness of local planning practice follows and then the paper considers the questions which should be addressed in land use and environmental issues in the UK.  相似文献

The concern of this paper is with the spatial consequences of development in a given rural setting and the way in which physical planning fits into the revival of a dying rural area, particularly in Third World Countries. It is based on experience derived from Dekinal in Benue State, Nigeria and endeavours to define a rural area by briefly discussing its characteristics and highlighting its problems. It proposes a comprehensive development planning process to induce development based on available resources.  相似文献

The medicinal and aromatic plants resources of Uttarakhand, India offer significant opportunities of employment and livelihood for rural communities and contribute a large share in the medicinal and aromatic plants trade of India. With the growing trade of medicinal and aromatic plants resources in the global market, the medicinal and aromatic plants business of Uttarakhand is also continuously growing in terms of trade volume, value and market reach. But, considering the ecological importance as well as unregulated exploitations of these resources, the growing business activities in this sector appear incompatible to the sustainability agenda. Through a mini review, this study assesses the medicinal and aromatic plants sector of Uttarakhand and identifies key challenges that seem incompatible for resource and business sustainability and offers some prospective research directions essential for identifying pragmatic solutions to support sustainability in the sector. This review identifies nine key challenges to sustainability in Uttarakhandʼs medicinal and aromatic plants sector. It is therefore pertinent that future research focus on the prevailing challenges of the medicinal and aromatic plants sector of Uttarakhand to develop strategies for sustainable business prospects.  相似文献

Building uses a combination of materials resources ranging from clay to bronze. Some of these resources are widely available, but require substantial energy resources to process and distribute them as the volumes used are so great. Other resources, like copper, are in much smaller supply. The resources used in building need to be examined against the future resource limitations in their supply and the possibilities of recycling. The links between building and waste cycles will also be critical, as wastes from other processes can often be incorporated into the building process. Design for recycling has to be balanced against the advantages of design for longer life. Reversible cementitious processes could confer enormous advantages if the reversibility was safely controllable, but this represents a very formidable scientific problem. The advantages of composite materials need to be balanced against the difficulties of effective recycling, for example reinforced concrete. The building as an energy conservation device also needs more emphasis. The final section deals with the concept of the materials conservation city in a Utopian way. It is designed to stimulate constructive thinking about resource conservation and materials recycling.  相似文献

ABSTRACT

Small-scale ecological farming and their associated alternative food networks, are increasingly important in China, as a response to poor farm incomes and as a contribution to widespread concerns about environmental degradation and food safety. However, despite the enormous market potential and the notable success of some ventures, this type of farming remains at the margins, with many businesses struggling to develop beyond their start-up phase and consumers struggling to build confidence in the new produce and routes to market. Many of these farms display the classic elements of pioneer businesses, including high reliance on charismatic individuals, insecure land rights, high transaction and monitoring costs and fragile routes to market. Empirically, many of these businesses fail because they cannot grow out of the pioneer phase before the pioneer grows tired of the business. While this is a problem for all small businesses, it is particularly acute in business sectors like ecological farming in China, where there is little evidence of suitable and sustainable developmental models. Using Bernardus Lievegoed's work on organisational development applied to two case study farms, we suggest that there are Western developmental models that are applicable to small-scale ecological farming and that have the potential to offer insights into how this might be achieved with Chinese characteristics. We conclude by arguing that, Chinese ecological farms have to plan explicitly for a form of development that allows them to remain committed to their ideals while moving them away from dependence on charismatic people, family labour and volatile customer bases.  相似文献

The behavior of individuals currently living will generally have long-term consequences that affect the well-being of those who will come to live in the future. Intergenerational interdependencies of this nature raise difficult moral issues because only the current generation is in a position to decide on actions that will determine the nature of the world in which future generations will live. Although most are willing to attach some weight to the interests of future generations, many would argue that it is not necessary to treat these interests as equivalent to those of the current generation. A common approach in this context is to use a system of discounting to evaluate future benefits and harms. This paper assesses the logic of discounting drawing on the writings of economists and philosophers. Much of the economic literature concerns the choice of an appropriate social discount rate. The social discount rate can be taken to reflect beliefs about the rights of future generations, a subject that has been extensively debated in the phioosophic literature. The writings of both economists and philosophers concerned with the weight to attach to the interests of future generations are reviewed and evaluated in this paper and the implications for environmental policy are discussed.  相似文献

The primary role of the Commission on Sustainable Development is to monitor progress in the implementation of Agenda 21 of the United Nations Conference on Environment and Development (UNCED, Rio de Janeiro, June 1992) and to suggest steps that governments and sectors of civil society can lake to move forward on its implementation. The CSD is to consider information provided by governments and to make appropriate recommendations to the General Assembly keeping in mind that national governments have the main responsibility for implementing Agenda 21.  相似文献

The Atatürk Dam was constructed on the Euphrates River in Turkey in the 1980s as the central component of a large-scale regional development project for the South-eastern Anatolia region, known as GAP. Since the first development plan for the region was presented in 1970, the objectives for regional development have changed significantly.
This article aims to analyze how the functions, design, and capacities of the Atatürk Dam project have been modified since 1970, paralleling changes in the regional development objectives and ambitions, and to identify accomplishments and constraints in the realization of the dam project.
Since 1970, ambitions to develop the region have grown significantly, resulting in major changes to the original project plans. The most important change occurred in 1978, when the design for the Middle Karababa Dam, recommended in 1970, was abandoned and the Atatürk Dam design was adopted. This change considerably increased the storage and power generation capacities of the dam. Yet, the sparse rainfall throughout the catchment in recent years has hampered full utilization of the dam's storage and generation capacities and increased the need for tradeoffs between conflicting demands for water use.  相似文献

The aim of the East Anglian Waste Minimisation in the Food And Drink Industry Project was to develop waste minimisation capability in food and drink sector companies by providing a structured training programme and consultancy support to participating members of a business club. The business club forum provided the structure within which interactive training and development sessions were delivered. Expertise and assistance in implementing waste minimisation and waste management programmes was given to member companies at their sites.The project resulted in pound 1,800,000 per annum of identified savings with pound 1,100,000 of verified savings already achieved. Training and development contributed fundamentally to these project outcomes and achievements.The structured training package used three different approaches or methods. Teaching and workshop sessions were used to present interactive training on waste minimisation practice. These were supplemented by interactive 'report-back' sessions where the 'project champions' presented progress reports to the club on waste minimisation at their sites.An overview of the business club approach is described, together with an account of the successes and challenges of applying a structured training and development programme and the barriers to waste minimisation that were overcome. Training effectiveness was measured according to reaction, learning, application and impact.  相似文献

Summary Increasingly stringent environmental lesislation and a growing consciousness of environmental issues within the community are spurring companies into adopting environmental improvement programmes. Enhanced environmental management not only ensures compliance with legislation but has other benefits, including reduced energy and waste disposal costs, improved public image, acess to green markets and lower insurance premiums. BS7750 and the Eco-Management and Audit Scheme now offer businesses the opportunity to establish a systematic and accredited environmental management system which will serve as a yardstick of environmental quality.  相似文献

The Earth has enough for everyone's need but not for everyone's greed. (Gandhi, 1947). A statement made when the world's population was 45% and global consumption was 25--30% of today's figures.The triad of problems, population, environment and development, is now being joined by a fourth, consumption. In many respects this could prove to be the least tractable of the four interlinked problems, since consumption patterns and expectations are deeply entrenched in most societies and cultures. However, change will come, whether by design or by default. The present consumption--or rather, excessive and wasteful consumption--on the part of rich nations cannot be sustained for environmental reasons alone, as exemplified by the fossil fuel/carbon dioxide connection to global warming. Nor can the present consumption in developing nations--meagre as these levels are for the 3 billion people who account for only 5% of the global economy--climb to levels desired by many if only because of the sheer numbers of their potential consumers. At the same time, it is increasingly the case that in the food sector, as in certain other sectors, over-consumption among rich communities can lead to under-consumption among poor communities. Fortunately, there are many opportunities to relieve consumption pressures, whether through enhanced technology or shifts in lifestyles, both of which can be promoted by a variety of policy initiatives.  相似文献

Problems of sustainable development and environmental protection pose a challenge to humanity unprecedented in scope and complexity. Whether and how the problems are resolved have significant implications for human and ecological well-being. In this paper, I discuss briefly recent international recommendations to promote sustainable development and environmental protection. I then offer a perspective on the roles and prospects of the university in promoting sustainable development and environmental protection.  相似文献
