A methodological assessment of raw materials in the UK

Many projects have attempted to model the consumption and recycling patterns of important raw materials, but without assessing the significance of that raw material to the UK. This article methodically assesses all the factors which influence the importance of each raw material, and ranks them in descending order of importance. Sensitivity analyses confirm that the resultant ranking is largely independent of factors used. Copper, oil, iron and steel, and aluminium, are the four most significant materials. This work provided the justification for a detailed examination of the copper industry and, in particular, the significance of recycling.     

Steel consumption and economic activity in the UK: The integration and cointegration debate

This research examines whether a long-run stationary equilibrium relationship holds between economic activity and the consumption of crude steel within the UK. Using the theory of fractionally integrated and cointegrated processes, and allowing for the possibility that the equilibrium path changes abruptly at occasional points in time, it is possible to determine if steel consumption and economic activity follow a common stochastic trend or whether the two series randomly drift apart over time. Evidence is found to support such a long term relationship. This result is at odds with the conclusions drawn by previous researchers in the area. The reason for this difference may be due to these researchers concentrating only on I(0) and I(1) specifications, without consideration of fractional possibilities and also to a failure to account for structural breaks in the equilibrium relationship. Such conclusions are made within the framework of the ARFIMA methodology that yields reliable inferences on the degree of fractional integration and cointegration. Critical values for fractional contegration with an ARFIMA model in the presence of structural breaks are also derived in this paper.     

Resource implications of materials waste in engineering manufacture

A quantitative analysis is presented of not only the direct but also of the indirect effects resulting from the fact that waste in any one part of a nation's industrial structure also induces waste in other parts.     

Pro-Poor local economic development in South Africa: The role of pro-poor tourism

This paper describes features of the emerging nexus in South Africa between tourism, poverty alleviation and local economic development (LED) interventions. The South African experience of evolving a strong pro-poor focus in LED planning is distinctive in the international context of writings on LED. Pro-poor LED is increasingly the outcome of the application of measures and programmes that are linked to the approach of pro-poor tourism in both rural and urban areas of South Africa. Two studies are presented of Alexandra township, Johannesburg and the Madikwe Game Reserve in North West Province as examples of pro-poor tourism as a form of pro-poor LED. It is argued that the growth of pro-poor tourism initiatives in South Africa suggests that the country is currently a laboratory for the testing and evolution of new approaches towards the planning of LED that potentially will have relevance for other countries in the developing world.     

The role of economic invisibility in development: veiling women's work in rural Pakistan

The thesis in this article is that both women's work and its invisibility are essential to development, and at two levels: to the economy of rural households and to the wider development process. For rural households, the case of Pakistan suggests that the veils that conceal women's work shield a portion of household production from the risks and extractions inherent in their involvement with development. This shielded production depends on off-farm natural resources of which the use is also veiled. For States and other development interests, the author suggests that women's work constitutes a subsidy which is intentionally invisible. The subsidy of women's labour is linked to a forest-to-farm subsidy. Women's invisible work, in other words, is not invisible because it is not seen, but because the process of economic development—for both rural households and States and other development actors—requires that it be hidden.     

Greener local economic development: Reflections from the UK on current European approaches

This paper considers moves to integrate environmental and economic development policies at local level. It provides a brief review of the EU policy frameworks and funding programmes which give a lead to, and support, local authorities in these efforts. Ecologically based approaches to local economic management are particularly highlighted. Municipalities typically employ a mix of regulatory, financial and voluntary measures to improve the environmental performance of businesses, create jobs and work towards greater local self-reliance. With the help of recent examples, the paper explores the variable scope for action—very much dependent on the national context—and identifies some mechanisms which are being used to good effect elsewhere in Europe but which are currently not easily transferable to the UK. Through programmes encouraging networking and the exchange of experience, UK practitioners can gain access to a range of European practice which demonstrates that greener local economic development is a real possibility.     

UK balance of payments in raw materials: A statistical analysis with implications for possible national materials policies

The author discusses the concept of a national materials policy for the UK and focuses on the implications for such a policy to be derived from analysis of the UK balance of payments. The position of materials in the overall trade balance, the role of individual commodities, the form of metal imports and the sources of supplies are all examined statistically to consider what are the major trends in materials trade.     

Analysis of the role of waste minimisation clubs in reducing industrial water demand in the UK

As a result of the UK Government's waste policy, which increasingly encourages sustainable development, and the realisation that water in the UK cannot be treated as an unlimited resource, there is growing interest in reducing the demand for water by industry. A series of industrial waste minimisation clubs have been set up within the country. This paper identifies the effectiveness of these clubs in reducing the demand for water. An overview of some of the clubs show how there is a major discrepancy between potential and implemented water savings, whilst a more detailed analysis of three specific examples show how water demand and cost to the company can be reduced, with the project paying for itself within around 1 year. It appears that companies are able to reduce water consumption by approximately 30%. If this level of saving was taken up by the entire industrial sector in England and Wales, water consumption could be reduced by approximately 1500 Ml/day. This reduction would be more significant in regions of lower rainfall, for example East Anglia and Southeast England.     

The economics of waste disposal in the UK

The author takes a simplified look at the structure of waste disposal costs in the UK. The immediate impression is that landfill costs are so significantly cheaper than other disposal options, on average, that considerable escalation in landfill costs, for whatever reason, would be needed to make it lose its predominance. The analysis also demonstrates that the more futuristic technologies may well have a role to play provided the initial estimates of per tonne costs are borne out by commercial ventures.     

UK electricity requirements and the environmental and economic aspects of the development of the combined cycle power station

In the space of three to four years, gas has changed from being a premium fuel, not to be utilized in power stations, to virtually the only fuel being considered for future electricity generation in the UK. This paper reviews the growth in the use of gas for electricity generation within the UK, with particular regard to the adoption of the gas-fired combined cycle power station. The environmental, economic and strategic issues associated with the proposed development of approximately 27 GW of new gas-fired plant are analysed and the resulting effects on existing base load power plant within the UK are considered.Dr James W.S.

Water and economic development: The role of variability and a framework for resilience

The article advances the hypothesis that the seasonal and inter‐annual variability of rainfall is a significant and measurable factor in the economic development of nations. An analysis of global datasets reveals a statistically significant relationship between greater rainfall variability and lower per capita GDP. Having established this correlation, we construct a water resources development index that highlights areas that have the greatest need for storage infrastructure to mitigate the impacts of rainfall variability on water availability for food and basic livelihood. The countries with the most critical infrastructure needs according to this metric are among the poorest in the world, and the majority of them are located in Africa. The importance of securing water availability in these nations increases every day in light of current population growth, economic development, and climate change projections.     

The Effectiveness of the UK Landfill Tax

This review of the UK's landfill tax generates two main contributions to our understanding of waste management in the UK. First, the review identifies areas in which the tax is least effective and considers policy implications associated with this. In particular, the tax has failed to significantly change the behaviour of domestic waste producers and SMEs. Second, it identifies continued information gaps that might be addressed. In particular, the landfill tax is intended to contribute to a transition away from landfilling of waste, towards recovery, recycling, re-use and waste minimization. This review of available evidence finds that there is reasonable data to monitor progress towards recycling, but not for re-use or waste minimization.     

Assessing the role of economic actors in the production of private and public goods in three EU agricultural landscapes

The study analyses the contribution of relevant economic actors to the provision of private and public goods in agricultural landscapes. A method consisting of a multi-sectoral perspective and an integrated approach based on the analytic network process (ANP) and the use of selected local stakeholders is applied. The usefulness of the method is demonstrated in three European case studies in Austria, Italy and Spain. The results show that agriculture and tourism are the sectors that contribute the most and the least, respectively, to the provision of goods and services in agricultural landscapes. Moreover, the results underscore that policy instruments towards such provision need to be targeted differently in different areas and must take into account the different roles of the local actors involved.     

US copper supply : An economic/engineering analysis of cost—supply relationships

The authors present short- and long-term supply schedules for the primary US copper industry. These schedules are based on the economic theory of supply, and are derived from site- and input-specific cost data. Cost figures are arrived at by a combination of engineering process analysis and statistical cost estimation. The supply functions can be used to evaluate the effects of changes in market, policy, or other variables on US copper supply.     

Agri-environmental schemes: their role in reversing floral decline in the Brue floodplain, Somerset, UK

This paper explores whether the introduction of an agri-environmental scheme has altered the course of long-term trends in plant species abundance in the Somerset Levels and Moors Environmentally Sensitive Area (ESA), UK. A semi-quantitative approach has been taken which integrates disparate but important historical datasets relating to flora and land management with more contemporary digital information. Species datasets from four time periods throughout the 20th century have been collated within a Geographic Information System and analysed with respect to ancillary data relating to elevation, under-drainage and ESA designation. Qualitative reconstruction of the historical ecology of this internationally important area of lowland wet grassland showed that a steady decline in abundance and extent of key components of the flora had already started by 1900. Analysis of historical under-drainage records dating from 1940s to 1980s showed a clear link between the length of time an area had been under-drained and the subsequent diversity of flora recorded in later surveys. In addition, the relative persistence of the rarer components of the wetland flora between surveys in 1980 and 1997 was related to the spatial pattern of under-drainage on the site since 1940. When overall species diversity was compared before and after ESA designation (1980-1997) there was some evidence of an increase in the number of species present and their spatial extent. The historical dataset provided useful contextual information with respect to species trends and allowed the interpretation of contemporary datasets to be placed within a longer timeframe. This pilot study using 18 species gives some evidence that long-established trends in species decline in the Somerset Levels and Moors ESA are starting to be reversed.     

Taking Venezuela back to the sustainability path: The role of financial development and economic integration in low‐carbon transition

Environmental protection and sustainable development are connected. Such connection is considered highly important for Venezuela, where fossil fuel abundance has created economic and environmental challenges. Surprisingly, only limited attention has been directed to identifying policy options for charting the path to sustainable development in the economy. Contributing to filling this gap in the literature, this study examines whether financial development, de facto and de jure conditions in trade and financial integration can trigger long‐term economic shifts that will change the trajectory of carbon dioxide (CO₂) emissions in the economy using a novel estimation approach—dynamic simulations of autoregressive distributed lag (ARDL) models. The empirical modelling framework incorporates the impact of population, economic growth, energy intensity and government consumption expenditure. ARDL‐bounds test provides evidence that the variables are cointegrated. Long‐run estimates from the dynamic ARDL analysis show that de facto and de jure conditions in trade and financial components of economic integration offer varied policy options for carbon mitigation in Venezuela. Population size, energy intensity, government consumption expenditure and de facto condition in financial integration have increasing impact on CO₂ emissions, exacerbating suitability challenges in the economy. On the other hand, positive shocks in financial development, de facto condition in trade integration and de jure condition in financial integration have a mitigation effect on CO₂ emissions. Overall, financial development, trade integration and the control of cross‐border financial flows are needed economic conditions that can accelerate a quick transition to a low‐carbon develpoment in Venezuela.     

The local authority EMAS in the UK: the Sutton model

The London Borough of Sutton was the first local authority in the UK to register units under the EMAS scheme. Working on a unit by unit basis the whole of the authority will be registered by the end of 1999. The EMAS was seen as the most appropriate tool for maintaining and expanding existing environmental initiatives in an increasingly restricted sector. The resulting new systems and work practices were seen to increase organizational efficiency by making sure that the right environmental questions were asked by the right people at the right time. The work has highlighted a number of strengths and weaknesses of the EMAS for local authorities and has highlighted the need for a more integrated approach in the future for local authorities to meet fully the needs of sustainability and Local Agenda 21.     

The north peak: an environmentally sensitive area in the UK

Summary Environmentally Sensitive Areas were introduced in Britain by the Ministry of Agriculture, Fisheries and Food during 1987. By 1994, the fourth round of designations had brought the total of such areas to 22. The environmental implications for the North Peak, which was designated as such an area in 1988, are discussed in the context of sheep farming and heather management, for these have shaped the patchwork of moorland ecosystems that give the North Peak its unique character.Paul Perkins is a research worker at the University of Huddersfield. He is currently undertaking research into how derelict mining land in West and South Yorkshire can be reclaimed for productive use.     

Environmental management in the UK: The way ahead for business

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.
