Modelling and analysis of international recycling between developed and developing countries

To deal with the complexity of recycling, a wide variety of models have been developed, each serving a specific purpose. Despite the current trend increasing international trade in recycling-related material flows, the international dimension of physical and economic relationships in recycling is often ignored in current models and analyses. This paper develops a formal model of an international material-product chain (MPC) that represents the mechanism behind international recycling. The attention is focused on the case of a developed and a developing country that exchange material commodities, final products and recyclable waste. Among others, the model demonstrates that taking into account environmental externalities results in higher levels of recycling. Moreover, we show that international recycling is mainly driven by regional differences in the quantity and quality of factor endowments and economic efficiency of recycling. Given that industrialised countries are relatively well endowed with recyclable waste, the recovery rate usually exceeds the utilisation rate. In developing countries, an opposite pattern is observed.     

How multilateral financial institutions promote sustainable water infrastructure planning through economic appraisal: case studies from coastal cities of China

Sustainable urban water infrastructure planning is vital for all cities in developing countries, where rapid urbanization has exacerbated the increasingly burdened environment. Water sustainability is a prerequisite for economic growth, social equity, and living quality in urban areas. This paper documents the current challenges and summarizes the solutions adopted in water infrastructure planning and management. Then, case studies of how multilateral financial institutions have promoted sustainable water infrastructure planning through economic appraisal and the novel approaches adopted for sustainable water infrastructure planning and asset management, are presented for the three cities of Jiaozhou, Cixi, and Fangchenggang. Conclusions are made based on the comparison and analysis of the experiences drawn from the case studies of how economic analysis could help promote sustainable water infrastructure planning and management. It is illustrated that economic analysis that considers ecosystem services supply should be employed more in water infrastructure planning, operation, and management in China.     

Economic and financial analysis of harvesting and utilization of river reed in the Okavango Delta, Botswana

The Okavango Delta, the largest Ramsar wetland site, is one of the most resource-rich ecosystems in Botswana. A range of resources, including reeds, contribute in various ways to the well-being of many of the communities through subsistence and income generation. The economic value of reeds and other resources found in wetlands has been poorly understood, leading to the perception that wetlands are wastelands, and have little or no economic values. Such resources are therefore likely to receive lower priority in conservation when evaluated against other alternative activities. The aim of this research was to determine the benefit and financial and economic viability of harvesting river reed in the Okavango Delta. Primary data were collected through a structured questionnaire administered at three villages in the Okavango Delta. Secondary data were collected from existing literature. Financial and economic analysis was undertaken using static and financial models. Market prices were used to calculate the net income generated from the sale of harvested reed. The measurement criteria for static models were the annual net cash income, net annual economic benefit, and return on investment (ROI), while those under the dynamic models were the net present value (NPV), benefit cost ratio (BCR), and the net benefit investment (N/K) ratio. It was more financially profitable and economically viable to harvest and sell reeds at Shorobe village (a village relatively close to the District economic centre, Maun), than Shakawe or Etsha-13.     

Economic and financial analysis on rainwater harvesting for agricultural irrigation in the rural areas of Beijing

Since 2006, around 600 rainwater harvesting systems have been constructed for agricultural irrigation in Beijing. The financial and economic implications of using these systems are discussed less. It is important to understand the effectiveness of the investments spent on the rainwater harvesting systems. The paper aims to analyze economic and financial performance of the constructed rainwater harvesting systems in rural areas of Beijing through the method of cost benefit analysis. The economic analysis focuses on determining the contribution of rainwater harvesting systems to the development of society, carried out from the point of view of government. The financial analysis allows comparison of the financial implications of using groundwater with using rainwater for agricultural irrigation from the point of view of individual participant, namely the local farmers. The results show that the rainwater harvesting systems are economically feasible. This means rainwater harvesting have positive effects for society. However, the financial feasibility of rainwater harvesting systems depends on the charge for groundwater and on the size of the rainwater harvesting systems. If groundwater is not charged, the rainwater harvesting systems are not financially feasible. If groundwater is charged at 2 Yuan/m³, only large size systems are financially feasible while small and middle sizes systems are not financially feasible. Under these circumstances, only large systems can run smoothly, while farmers may not use the small and medium-size systems.     

Food Sovereignty and Gender Justice

Food sovereignty asserts the right of peoples to define and organize their own agricultural and food systems so as to meet local needs and so as to secure access to land, water and seed. A commitment to gender equity has been embedded in the food sovereignty concept from its earliest articulations. Some might wonder why gender justice should figure so prominently in a food movement. In this paper I review and augment the arguments for making gender equity a central component of food sovereignty. The most common argument is: if women constitute the majority of the world’s food producers, then agricultural policy is a women’s issue. And insofar as patriarchal social relations continue to dominate the globe, then changing agricultural policies will require explicit attention to gender injustice. I suggest that this is a good argument, but that an ecological feminist perspective can provide additional theoretical reasons for maintaining the centrality of gender justice in food sovereignty discourse. Moreover, ecological feminism can provide a robust theoretical framework that coheres a concept and movement with a wide set of concerns. My critique positions food sovereignty’s call to social justice as embedded in a truly radical re-thinking of dominant conceptual frameworks, and re-envisioning of political and ethical relations.     

Regional intergovernmental institutions: Participation benefits and costs

Evaluators frequently cite the absence of effective participation by constituent governments and the need for consensus or even unanimity prior to action as the causes of poor performance by regional resource management institutions. Major governments either will not join the regional institution, will not participate even if legally members, or will exercise a veto over many important management projects.This paper examines the variables that may cause these problems and provides an improved understanding of why rational political actors would act in ways that inhibit the efficient management of resources. Among the principal variables determining participation are expected benefits of collective decisions, perceived losses of autonomy and representation, the number and homogeneity of other participants, decision costs, and the decision rule used to determine actions. Analysis of these factors suggests why consensus and unanimity decision rules are frequently chosen and why participation is usually limited.     

Seabed resources and international law

This article outlines the problems related to the exploitation and allocation of undersea resources. The nature and accessibility of undersea petroleum supplies and metalliferous nodules are described in terms of the existing and prospective future economic constraints. Since the majority of such resources lie outside national jurisdictions, their ownership has recently become a major source of international conflict. The character of that conflict is explained, and the prospective solutions under international law are identified. Unilateral action on the part of countries possessing the requisite technologies to exploit these resources is viewed as the most probable near-term outlook, even though it may not satisfy very many aspects of international equity.     

A multi-disciplinary framework to monetize financial consequences arising from CCS projects and motivate effective financial responsibility

Carbon dioxide capture and storage (CCS) holds promise as a safe and effective approach for addressing climate change. However, concern about potential “liability” associated with CCS often is cited as a significant barrier to project deployment. The authors contend that, in this context, the term “liability” is poorly defined and conflates concerns about the uncertainty in the timing and magnitude of potential damages with the need for financial responsibility for long-term stewardship of certified closed sites. This paper offers an analytic framework drawn from damages estimation methodologies used in comparable contexts and incorporates risk-based probabilistic modeling to assist stakeholders in evaluating the potential environmental, human health and financial consequences of CCS projects. Application of the proposed framework will achieve four distinct objectives. First, the outputs of the analyses – monetized damages estimates for adverse impact scenarios coupled with expected loss calculations that reflect scenario probabilities and identify the statistical range of possible outcomes, including “most likely” loss estimates – will help interested stakeholders consider the viability of various investment and financial risk management strategies. Second, the results can be used to develop or negotiate financial assurance instruments for analyzed projects. Third, the results will inform the public policy debate regarding the degree and magnitude of potential financial consequences resulting over the long-term, beyond an established post-closure period. And, fourth, while the detailed conceptual framework, resulting models, impact calculations and valuation analyses may be applied on a site-by-site basis, the site-specific results could be pooled to assess regional and national implications of various risk mitigation and financial risk management policies.     

Economic and financial aspects of mine closure

Today, mine reclamation is a key component to a successful mine plan. Most of the industrialized nations have recognized the need to make mining activities relatively environmentally friendly, if they want to continue to benefit from the economic gains from mineral resource development. Countries such as the United States, Canada, Australia and South Africa are leaders in the field and have implemented relatively sophisticated legislation to ensure environmentally correct mine closure. These countries rely on a combination of strict control strategies and economic penalties to ensure compliance. Yet, from the firm's perspective, reclamation activities are counterproductive as they cut into profits. In order to attract economic development and earn much needed economic capital, most of the rest of the world, particularly the developing countries, lack effective mine closure legislation. The traditional command and control type of legislation that is sometimes used is either vague and therefore avoided, or not enforced appropriately, resulting in an undesirable level of environmental degradation. With the use of case studies from Brazil, this article shows that direct controls are effective in some instances and not in others. It proposes that economic and financial tools may be more effective than the traditional direct controls in getting firms to comply with environmental standards, particularly in developing countries where environmental compliance is more difficult to achieve. It explains the use of performance bonding as one type of economic incentive that has proven to be an effective environmental policy in mine planning and closure. The authors additionally push beyond the typical style of performance bonds to introduce a flexible bonding and insurance system that allows governments to maintain strict environmental standards but limits firms financial exposure during the mining process. Such a system learns from the successes of the industrialized countries that use performance bonding and is sensitive to the needs of developing nations to attract investment yet maintain environmental integrity.     

Irrigation activities and institutions in Kenya's Lake Victoria Basin

Irrigation activities in Kenya range from large-scale government-owned schemes involving thousands of acres on which farmers work for wages to small individually owned and irrigated plots of three or four acres. This paper examines the institutions and operational workings of the government schemes as well as the privately owned plots. In general the most successful irrigation schemes are those which are organized and run by individuals or by private groups with government agencies and NGOs providing technical support.     

Environmental management systems in further and higher education institutions

Many people within the further and higher education sector in the United Kingdom (UK) have now accepted that responsible environmental management of their day to day site operations is necessary, but they are still unclear as to what lengths they need to go to obtain marketplace credibility. Many people in other sectors believe that the only way to achieve real credibility in this area is to become accredited by the new British Standard BS7750 Specification for Environmental Management Systems. Others are expressing concern that such systems are cumbersome to operate and generate a needless level of bureaucracy and additional unwelcome paperwork.This paper briefly discusses the responsibilities of further and higher education institutions with regard to environmental management and outlines one possible alternative to the BS7750 approach, the Confederation of British Industry (CBI) Environment Initiative. It also outlines the approach taken by the University of Strathclyde over the past three years in the development of an environmental management manual for the Estates Management Department and the development of a system to control university-wide environmental management.In conclusion this paper will focus on the suitability of BS7750 systems within further and higher education institutions in comparison with the approach adopted in the CBI Environment Initiative.This paper was first presented at Global Forum '94 Academic Conference Towards a Sustainable Future: Promoting Sustainable Development, Manchester, UK.Mr K. McDonach is a research assistant and Dr P. Yaneske is Director in the Safety and Environmental Management Unit of the University of Strathclyde.     

Indigenous economic institutions and ecological knowledge: A Ghanaian case study

Increasingly, the urgency of reorienting conventional development paradigms to take into account indigenous institutions and their ecological knowledge base is being recognized in both developed and developing countries. Based on a field research in Ghana, this paper discusses the nature and operation of indigenous economic institutions, their ecological knowledge, norms, beliefs, and practices pertaining to sustainable utilization of natural resources and environmental management. The institutions provide a framework of ideas, guiding principles, and practices that could serve as a foundation for endogenous options and broad-based efforts to solving resource and environmental management problems in the developing world. The paper also discusses limitations of indigenous ecological knowledge and practices.     

Petroleum prospects and the need for international cooperation

A review of the world energy situation prior to the Persian Gulf War of 1990-91 shows that periods of oil price instability have distorted the decision-making process. During periods of high prices, investments were made in uneconomic energy sources and in periods of low prices few investments were made at all. To create a rational investment climate, international cooperation between consumers and producers of petroleum is essential. Such cooperation in the form of a forum could help to stabilize prices and assure that the economic decisions needed to meet future demand would be made in a secure framework.
