A critical look at residential electricity conservation campaigns in a developing country environment

This paper analyses survey results of the effectiveness of information campaigns to promote energy efficiency among residential consumers in Brazil. The survey found that consumers have a relatively good knowledge of conservation measures to improve electricity usage. Nevertheless, other approaches are needed to promote energy conservation in the household sector.     

China: Energy and environment

Some of China's most prominent environmental problems are related to energy The air pollution of the cities and industrial centers is caused by the inefficient combustion of coal. Deforestation is due to a certain extent to the procurement of firewood. Further problems are caused by the ash and slag from coal combustion and the oil pollution of the sea. While most of China's air is still clean, pollution levels in the cities surpass by far those of German industrial towns, and the health effects are becoming apparent The problem of deforestation must be considered still more serious because it affects whole regions. Short-term effective solutions to the problems presented are not available     

Corporations and the environment: A new perspective

Summary The author presents the results of a pilot study which explored the voluntary support given by seven Pittsburgh multinationals to environmental goals and objectives through their foundations and operations. While much of the information is national in scope, the findings have international significance. Fundamental common key factors and patterns were identified which already have and will continue to guide most corporate international environmental activities. As interest grows in developing cooperative undertakings with the corporate community, it is important for environmental organizations, government, and academia to understand these patterns. Based on the findings and on suggestions by corporate representatives, recommendations are given as to how support of the goal of creating sustainable societies by the corporate and environmental communities can be improved and increased. Dr Langord's interest in urban and environmental policies range from issues dealing with coastal zone and floodplain management to urban waterfront re-vitalization and environmental aesthetics. Most recently she is studying the role of industry in helping to meet critical resource and environmental needs. She is exploring new patterns of cooperation with government, industry and environmental organizations. Currently Director of the International Environment Program, Center for International Studies, University of Pittsburgh, Dr Langord has held a number of academic positions, served as a resource policy analyst for the US Department of Interior, and has acted as a consultant to government and industry.     

Green product purchase intention: Some insights from a developing country

This paper examines from the motivational perspective of the Theory of Reasoned Action (TRA) how individual values and attitudes in a developing country influence purchase intention of a green product. It also investigates how values may affect attitudes towards environmentally responsible purchase intention. The study analyzed data collected from 257 working respondents who were asked their views concerning their value sets, attitudes and purchase intention of cloth diapers using the Structural Equation Modeling (SEM) technique. Findings indicate individual consequences relating to amount of effort and convenience of consumers is negatively related to intention to purchase green product. Environmental consequences are not a significant predictor of environmentally responsible purchase intention. Conservation value was found to be positively related to attitude on environmental consequences but less intensely with individual consequences while both self-transcendence value and self-enhancement value were positively related to individual consequences. Individual consequences and self-enhancement value were negatively related to environmentally responsible purchase intention. This paper has shown that the extended TRA is applicable and also this paper has enhanced understanding of predictors of environmentally responsible purchase intention in a developing country context.     

Environmental system management and governance needs in a developing country

Environmental governance in the twenty-first century in Bangladesh faces serious challenges in terms of improving service delivery. There are surfeits of laws, rules and regulations as well as institutions to manage and govern the environmental sector. The legal regime is quite comprehensive, yet little attempts have been made so far to iron out the contradictions and duplications among existing rules and regulations. Institutions continue to suffer because of a number of reasons. Coordination among different ministries and other agencies in the governmental and non-governmental sectors is poor. Inter-organizational meetings and other follow-up meetings are not regularly held and usually fail to achieve their intended objectives. Though attempts have been made to involve people at the formulation stage of action plans, seldom people are taken into confidence and consulted with when these plans are implemented. One of the consequences of such a situation is people’s lack of interest in government-sponsored environmental protection programs. The decision-making procedure/situation of different environmental development projects and policies did not follow the holistic or coordinated principles so that post-impacts of works appeared vast and diverse conflicts. This paper tries to search the history of environmental protection of Bangladesh, relevant environmental laws, rules, regulations and projects and major international conventions, treaties, and protocols signed or ratified by Bangladesh as well as investigates the current situation, mechanism and decision making regarding environment in the context of environmental governance, analyzing the problems and also explored the challenges for environmental management in Bangladesh and associated problems and risks of system and finally proposed some core guidelines of effective environmental governance and system management for Bangladesh.     

Bioethics of fish production: Energy and the environment

Aquatic ecosystems are vital to the structure and function of all environments on earth. Worldwide, approximately 95 million metric tons of fishery products are harvested from marine and freshwater habitats. A major problem in fisheries around the world is the bioethics of overfishing. A wide range of management techniques exists for fishery, managers and policy-makers to improve fishery production in the future. The best approach to limit overfishing is to have an effective, federally regulated fishery, based on environmental standards and fishery carrying capacity. Soon, overfishing is more likely to cause fish scarcity than fossil fuel shortages and high energy prices for fish harvesting. However, oil and other fuel shortages are projected to influence future fishery policies and the productive capacity of the fishery industry. Overall, small-scale fishing systems are more energy efficient than large-scale systems. Aquaculture is not the solution to wild fishery production. The energy input/output ratio of aquacultural fish is much higher than that of the harvest of wild populations. In addition, the energy ratios for aquaculture systems are higher than those for most livestock systems.     

Packaging waste and the polluter pays principle: a taxation solution

Packaging waste has become a focus for attention by policy‐makers in a number of countries. This article offers a simple policy measure — a packaging tax or levy — which serves the required aims of policy, namely: reducing waste at source; increasing the rate of recycling; and consistency with the polluter pays principle. The tax is illustrated in the context of beverage containers in the UK and Japan. The merits of the proposal are its simplicity and flexibility. The article suggests that the relevant environmental damages are captured by waste disposal costs and litter. Other life cycle impacts, such as emissions from energy use, could be included but only if there are not more efficient ways of regulating them.     

Energy and environment in the European Union: An indicator-based analysis

The European Environment Agency (EEA) is the European Union body dedicated to providing sound, independent information on the environment. It is a major information source for those involved in developing, adopting, implementing and evaluating environmental policy in Europe, and also for the general public. In line with its mandate, the EEA has developed — focused around a set of policy relevant questions — a set of indicators to assess progress in Europe in integrating environmental considerations into the energy sector. Each question is answered through one or more indicators describing the development of the sector in Europe, implications for the environment and links to policy actions. The indicators cover not only the current situation, but also trends and prospects and, most importantly, point to the conditions for change that are needed for progress towards a more sustainable energy policy that benefits the environment. The results of the most recent assessment are presented in this article and show that in many areas of environmental integration there have been some successes, but overall progress to date has been insufficient. Substantial additional action will therefore be required in the future if the European Union is going to move towards a more environmentally sustainable energy system.     

Energy and environment scenarios for Senegal

In this paper, the energy and environmental dimensions of several proposed energy strategies for Senegal are explored. An analytical framework to compare the energy and measurable environmental impacts of a set of scenarios is developed, and the limitations of the quantitative approach are discussed. It is found that policies to promote substitution of liquid petroleum gas (LPG) for charcoal use in households may actually reduce greenhouse gas emissions, while also improving more important near-term environmental problems. Substitution of LPG for charcoal would not necessarily lead to a significant increase in Senegal's oil import bill, since other petroleum product usage will continue to dominate. Despite past industrial sector initiatives, considerable potential for energy efficiency investment remains, and presents additional opportunities for minimizing environmental impacts.     

An ecological perspective on nanomaterial impacts in the environment

Growing concerns over the potential for unintended, adverse consequences of engineered nanoparticles (ENPs) in the environment have generated new research initiatives focused on understanding the ecological effects of ENPs. Almost nothing is currently known about the fate and transport of ENPs in environmental waters, soils, and sediments or about the biological impacts of ENPs in natural environments, and the bulk of modern nanotoxicogical research is focused on highly controlled laboratory studies with single species in simple media. In this paper, we provide an ecological perspective on the current state of knowledge regarding the likely environmental impacts of nanomaterials and propose a strategy for making rapid progress in new research in ecological nanoscience.     

Energy and environmental challenges for developed and developing countries

A supply-oriented strategy which accepts current projections of development energy demands, and seeks to satisfy them, based on acquiring capital-intensive technologies requiring imported fuels is doomed to failure. Developing countries which follow such a strategy will be unable to meet either their energy needs or the basic development needs of their people. To the extent that their energy needs are thus met, it will be at horrendous cost of capital desperately needed for economic and social improvement in non-energy sectors and with tragic environmental consequences to the developing countries and to the world [17]. The opposite of a supply-oriented strategy is a demand-control one. Commercially available or near commercial energy efficient technologies will permit the developing countries to raise the standard of living of their people with only a modest increase in per capita energy consumption.     

Energy efficiency in developing countries Policy options and the poverty dilemma

Much of the rural population of the developing countries is poor and depends on agriculture for its living. One means of improving the standard of living of such poor peoples is through the introduction of modern more intensive and therefore more productive agricultural methods. Such methods will require energy intensification. The resulting increase in energy demand particularly electrical energy, will be very large, especially because the rural areas are least able to benefit from energy saving technologies.     

Universities,government, and industry: An international perspective on developing environmentally conscious technologies

The educational and research roles of universities in environmentally conscious technologies are discussed from a historical perspective. The American university system, and in particular its interactions with government and industry, is compared with that of the United States' main trading partners including Japan, the NAFTA countries, and Western Europe. Examples of federally funded U.S. programs related to green design are also tabulated. The role of universities within the framework of society, politics, and economics is discussed in regard to emerging concepts such as sustainable development, life-cycle analysis, and design for environment, as well as the functioning of local recycling infrastructures. The means by which universities can contribute to environmentally conscious technology are summarized, as are the demands placed on the next generation of engineers.     

Farming in the urban environment of a developing nation — a case study from Ibadan metropolis in Nigeria

Summary The major characteristics, problems and prospects of farming in an urban environment of a developing nation are investigated using the Ibadan metropolitan area of Nigeria as a case study. Eight hundred farmers, made up of both part-time and full-time farmers were interviewed in five urban fringe settlements in the study area. Findings revealed that farming in the urban environment is guided by the logic of survival since most of the farmers engaged in urban cultivation are mainly low-income earners and they farm mainly to reduce their expenses on food and to supplement the family's income. The major problem confronting farming in the area is competition from non-agricultural land uses. Nevertheless, more than half (50.5 percent) of the farmers, who had been approached to sell their farmlands for non-agricultural uses in the area, rejected the offer, indicating that the prospects of continued farming are thought to be good. Measures like the sale of urban land at its agricultural value, provided the land remains in cultivation, as well as the further provision of land in and around the farmers' working places, could improve their access to land for extended farming.Dr Adeniyi Gbadegesin is a lecturer in the Department of Geography at the University of Ibadan. He has published papers widely on agricultural topics.     

South African gold mining taxation : An example of a resource rent tax

Theoretically, a resource rent tax is neutral in that it does not influence the allocation of resources. However, the application of such fundamental principles in the tax formula of the South African gold mining industry negates the neutrality principle. A progressive element in the tax rate encourages mining of submarginal ores - leads to misallocation of resources. However, it substantially reduces the financial risks of a mining company engaged in the extraction of a commodity characterized by price volability, such as gold, and permits economies of scale in mining and encourages conservation of a non-renewable resource. As long as prices increase faster than costs, the advantages of this system probably exceed the disadvantages. The choice of the threshold rate in such a tax system is critical. If it is too high it will encourage mining of submarginal ores, and if too low it does not recognize the peculiar risks of gold mining investments.     

Five propositions for improving decision making about the environment in developing communities: insights from the decision sciences

Decisions focused on managing natural resources in developing areas present some of the most imposing challenges to policy makers, scientists, and stakeholders alike. The response of policy makers and the technical community in the face of these challenges has been significant. However, our experiences as researchers and facilitators of group planning and decision-making processes have left us concerned about the lack of attention devoted to supporting the underlying processes used to make these complex decisions. To this end, we present five propositions based on work in the decision sciences that we believe stand out as essential for improving decision-making processes in developing communities.     

Small towns in the united states: a perspective

Small towns are an important part of the rural settlement fabric in the United States, but there is very little substantive research into their capacity to survive or their intrinsic importance. However, recently there has been increasing interest shown by social scientists in these problems. This paper looks at features of this research from the point of view of the population and economic structure of small towns. It concludes by arguing that the problems of small towns are not indigenous to the towns, and calls for a comprehensive national urban policy.     

Energy balance and global warming potential of corn straw-based bioethanol in China from a life cycle perspective

As the second largest corn producer in this world, China has abundant corn straw resources. The study assessed the energy balance and global warming potential of corn straw-based bioethanol production and utilization in China from a life cycle perspective. The results revealed that bioethanol used as gasoline and diesel blend fuel could reduce global warming potential by 10%–97% and 4%–96%, respectively, as compared to gasoline and diesel for transport. The total global warming potential, net global warming potential, net energy, and Net Energy Ratio per MJ ethanol generated from corn straw-based bioethanol system are estimated to be 0.20 kg CO₂-eq, 0.012 kg CO₂-eq, 0.60 MJ, and 1.87, respectively. By using sensitivity analysis, we found that the collected coefficient and compressing density of straw have a more obvious influence on energy balance; transportation distance has a more obvious influence on global warming potential emission factor. The by-products may be utilized as fertilizer, animal feed, cement replacement, or high-value lignin chemicals, which make a contribution to offsetting 0.28 MJ per MJ ethanol of energy consumption.     

Students' environmental concerns and opinions: a Chinese perspective

This study aims at comparing broadly the environmental concerns and opinions between Hong Kong and Beijing students. This is based on an earlier study in Australia which adopted a qualitative approach, using five open-ended question items. In their written comments the children's environmental opinions and concerns were explored. In general, upper primary students tended to be concerned more about the social environment relating to society, while junior and senior secondary students expressed more concern about the social environment relating to the nation and global issues.     

Issues in extractive resource taxation: A review of research methods and models

This paper provides a conceptual overview of economists′ attempts to learn about the effects of taxes on extractive resources. The emphasis is on research methods and techniques, with no attempt to provide a comprehensive tabulation of previous empirical results or policy conclusions regarding preferred tax instruments or systems. We argue, in fact, that the nature of such conclusions largely depends on, and is limited by, the researcher′s choice of modeling framework. Many alternative frameworks and approaches have been developed in the literature. Our goal is to describe the differences among them and to note their strengths and limitations.
