The conventional wisdom is that water resources should be managed on a basin-wide scale. However, a closer look at the scale of transboundary water institutions reveals that, for the most part, this is not the case. This study seeks to understand the gap between reality and theory by arguing that due to the common spatial discrepancy between benefits and costs of cooperation at the basin scale, other scales are advanced in order to offset this discrepancy. To test this hypothesis, the negotiation process over the spatial scale of the 1944 treaty between the US and Mexico over transboundary water is examined. The analysis of this case study indicates that due to its weakening position in an upstream/downstream conflict over the Colorado’s water in the early 20th century, Mexico demanded widening of the scale by integration of the negotiations over the Rio Grande with those over the Colorado’s water. This allowed the parties to trade the Rio Grande’s water for the Colorado’s and thus to offset the spatial discrepancies that precluded agreements in previous basin-level negotiations. However, this spatial strategy was found to have a high political cost, especially in the decentralized US system. Hence, the US had to use additional mechanisms to mitigate these internal transaction costs.  相似文献

This contribution to the Forum Debate on global development focuses on the dimension of functional income distribution between labour and capital and its demand‐side and supply‐side effects. The article summarizes recent literature that has sought to explain the reasons behind the global fall in the labour share. It then discusses the demand‐side effects of the declining wage share on growth, based on the post‐Keynesian/post‐Kaleckian literature. The author presents an alternative policy scenario for the G20 based on a mix of increasing wage share and public investment, before discussing the supply‐side effects of rising inequality. The article concludes with some policy implications for equality‐led development.  相似文献

This article addresses the future of freshwater resources in the Palestinian West Bank through a discussion of contemporary issues that each plays a vital role in determining the long‐term sustainability of freshwater reserves, such as water resource availability, trans‐boundary water issues, water reuse and conservation, changes in land use, and the potential impact of climate change on long‐term water management. Climate change and changing land use patterns are already altering this region's water resources. Future predictions regarding the long‐term effects of these changes are complex and therefore inherently uncertain. However, the consensus among most studies on this subject indicates that currently water‐poor regions such as the Middle East will experience even greater water stress in the future. Nearly all of the freshwater consumed in the West Bank is obtained from local groundwater supplies that are suffering overdraft as well as decreasing water quality. Climate change will exacerbate water stress by increasing overall temperatures, decreasing and fluctuating precipitation, and reducing overall aquifer replenishment. Expanding urbanization will continue to strain freshwater supplies by negatively impacting the quality and quantity of available freshwater. Water management in the West Bank is further complicated by total Israeli control over water resources, which often causes water delivery to Palestinians in this region to be marginalized. This article finds that Palestinian and Israeli water managers must plan for future water crises, which will likely be a result of the combined effects of increasing urbanization and climate change coupled with exponential population growth.  相似文献

East Asia has led the world in economic growth and export expansion in recent decades. The phenomenal rate of economic growth among the so‐called “four little tigers”—Hong Kong, Singapore, South Korea, and Taiwan—enabled them to achieve newly industrializing country (NIC) status in the 1980s, followed by Indonesia, Malaysia, and Thailand. Earlier studies explained the development from the government‐led development paradigm, or the so‐called the statist approach. Scholars also argue that foreign direct investment (FDI) played an important role in the economic development, thanks to technology transfers. Kojima and Ozawa and later Kohama, however, argue that Japanese FDI help East Asian economies while U.S. FDI do not because Japanese technology transfer practices are appropriate for East Asian countries but not the United States'. Thus, we revisit the issue of East Asian economic development and test the economic effects of FDI from the United States and Japan. Using a Barro‐type growth model, we test the effects of FDI from the United States and Japan on economic growth in East Asian NICs. We find that FDI from both the United States and Japan helped economic growth in the “four little tigers,” but not in Indonesia, Malaysia, and Thailand.  相似文献

Abstract

Two modes of using undergraduate students as peer teachers in introductory courses have been developed at the University of Colorado at Boulder. Peer teachers are small group leaders in a human geography course built around role playing simulations; in two physical geography courses they are tutors in a self‐paced system. A separate course provides peer teacher guidance—a course‐within‐a‐course model. Socio‐psychological, pedagogical, economic, and political implications of peer teaching are interpreted after ten years' experience with the programme.  相似文献

Conventional approaches to development in areas that are experiencing economic decline invariably focus on business growth through interventions such as incentives, infrastructure development and job readiness training. This paper reports on a pilot project aimed at developing an alternative approach to community and economic development in the context of the Latrobe Valley, Victoria, a resource region that has experienced downsizing and privatisation of its major employer, the state‐owned power industry. The project was shaped by a poststructuralist concern with the effects of representation. It sought to challenge familiar understandings of disadvantaged areas, the economy, community and the research process in order to open up new ways of addressing social and economic issues. The resulting four‐stage research project was informed by the techniques of asset‐based community development and action research, as well as by discourses of the diverse economy and communities of difference. During the two‐year span of the project, four community enterprises were developed. The varying degrees of success they have met with in the four years since the project concluded highlight the critical role of local agencies such as the council in providing ongoing support for such endeavours.  相似文献

Abstract: In response to the growth of private sector involvement in water supply management globally, anti‐privatization campaigns for a human right to water have emerged in recent years. Simultaneously, alter‐globalization activists have promoted alternative water governance models through North‐South red‐green alliances between organized labour, environmental groups, women's groups, and indigenous groups. In this paper, I explore these distinct (albeit overlapping) responses to water privatization. I first present a generic conceptual model of market environmentalist reforms, and explore the contribution of this framework to debates over ‘neoliberalizing nature’. This conceptual framework is applied to the case of anti‐privatization activism to elucidate the limitations of the human right to water as a conceptual counterpoint to privatization, and as an activist strategy. In contrast, I argue that alter‐globalization strategies—centred on concepts of the commons—are more conceptually coherent, and also more successful as activist strategies. The paper concludes with a reiteration of the need for greater conceptual precision in our analyses of neoliberalization, for both academics and activists.  相似文献

Across the fiction and non‐fiction writings of Edward Abbey (1927–1989), the anticipated restoration of Glen Canyon on the Colorado River is a recurring theme. This article employs Abbey's polemic for the removal of Glen Canyon Dam to critique contemporary debates on dam decommissioning, water politics, and ecological restoration in Glen Canyon on the Utah–Arizona border. The endeavours (and fantasies) of Abbey's fictional quartet of eco‐saboteurs reveal his radical and anarchical imaginings on how to remove the dam, yet his non‐fiction works often suggest why Glen Canyon should be restored. The politicisation of Abbey's philosophy is explored through (1) organisational, institutional responses to the question of draining Lake Powell reservoir and decommissioning the dam, and (2) how the ideology of Abbey's fictional gang is recast—and plays out—in the actions of environmental activists. This article argues that Abbey remains an important voice in the battle to restore the Glen.  相似文献

As wildfires increase in both severity and frequency, understanding the role of risk saliency on human behaviors in the face of fire risks becomes paramount. While research has shown that homebuyers capitalize wildfire risk following a fire, studies of the role that risk saliency plays on residential development is limited. This paper aims to fill this gap by studying the link between wildfire risk saliency and the rate of residential development in wildfire-prone areas, by treating recent wildfires as conditionally exogenous shocks to saliency. Using geospatial data on residential development in Colorado, we show that saliency shocks due to wildfire lead to statistically significant reductions in the rate of new development in wildfire risk zones that last upwards of 5 years, a result that is robust to a number of alternative explanations. We explore the policy implications of these findings, noting that education on fire risks may curtail some but not all of the development in these high wildfire-risk areas due to the rapid growth of development in these regions.  相似文献

There have been significant territorial changes in the Spanish Mediterranean in the last few decades because of the important growth of residential tourism functions. The Spanish National Hydrological Plan ( 2001 ) and, to a greater extent, the Action for Management and Use of Water Programme ( 2004 ) advocated large‐scale desalination of seawater to guarantee a supply for urban, tourism, and even future agricultural demands. The paralysis of urban development planning caused by the financial crisis (2007/08), together with the downward trend in the consumption of drinking water in the last decade, highlighted a capacity to produce desalinated water that was far superior to actual needs. This study reviews the current context in which desalinated water is produced in Spain, weighs up the advantages and disadvantages of this method of water management, and considers the potential role that this non‐conventional source of water could play as a strategic resource in the future. The main findings of the study are that desalination is not a panacea; rather, it should be considered in terms of technological parameters tailored to the circumstances of each geographical and socioeconomic environment.  相似文献

Local Media and Experts: Sources of Environmental Policy Initiation?   总被引:1,自引:0,他引:1  
Research on the process of policy change often involves a direct or indirect analysis of the roles of policy entrepreneurs and the mass media. In Colorado, beginning in 1998, twelve communities decided to obtain water rights for recreational in-channel purposes such as kayaking and whitewater rafting. These water rights stirred political controversy within some communities in Colorado related to spending public money, appropriate uses of water, and the role of recreation in local economies. Using a comparative case study research method, this research analyzes the role that policy entrepreneurs and local media coverage of recreational water rights played in initiating policy change in local communities. The most critical finding from this study is that in communities where citizens acted as policy entrepreneurs there was more controversy, less positive media coverage, and more media coverage early in the process. This case contradicts the assumption that local media coverage helps to highlight policy problems within communities. It supports the idea that experts wield higher levels of influence than citizens in promoting policy agendas.  相似文献

We analyze a two‐sector model of a trading creative regional economy (TCRE) of the sort studied by Florida. Our analysis focuses on two cases. The first case concerns the impact of faster neutral, whereas the second case concerns the impact of faster nonneutral, productivity growth in the tradable sector on the employment of creative people in each of a TCRE's two sectors. In both cases, the sign of the percentage change in the steady‐state use of creative capital in the nontradable sector is ambiguous. In other words, the potential departure of creative people from the tradable to the nontradable sector does not depend upon whether the faster productivity growth being studied is neutral or nonneutral. In addition, because the effects of faster productivity growth in the tradable sector are not necessarily innocuous, a potential role exists for activist policy designed to countermand the possibly negative effects of faster productivity growth on either the tradable or the nontradable sector. This finding of possible “uneven development” is consistent with Florida's view that TCREs can give rise to externalities such as uneven regional development.  相似文献

Salar Ignorado is a shallow acid saline lake hosted by a small intervolcanic basin high in the Andes Mountains of northern Chile. Modern surface waters have 3.3–4.1 pH, 0.5–3% total dissolved solids (TDS) and are actively precipitating gypsum crystals. The gypsum crystals trap the acid saline water as fluid inclusions, providing a record of recent surface water characteristics. Salar Ignorado gypsum contains three distinct types of primary fluid inclusions, which result from growth of the gypsum from surface waters. Petrography and microthermometry were performed on 27 gypsum crystals from Salar Ignorado to gain an understanding of recent water chemistry of the salar. One 18.3‐cm‐long gypsum crystal, hosting primary fluid inclusions along 28 successive growth bands, was the focus for fluid inclusion studies and allowed a record of high‐resolution chemical trends. This crystal showed a change in parent fluids during growth, from low salinity, to high salinity, back to low salinity. At the bottom of the crystal, the lowest six fluid inclusion assemblages have salinities of 1.7–5.1 eq. wt. % NaCl. The next nine fluid inclusion assemblages have significantly higher salinity (18.6–27.4 eq. wt. % NaCl) inclusions. The twelve fluid inclusion assemblages near the top of the crystal have low salinity (0.9–8.3 eq. wt. % NaCl) like those at the bottom of the crystal. The high‐salinity fluid inclusions in the middle of this gypsum crystal are interpreted to have formed during a pulse of magmatic/hydrothermal fluids to the surface, perhaps during local active volcanism. Secondary evidence of a magmatic influence on surface waters includes hydrogen sulfide and high molecular weight solid hydrocarbons within some fluid inclusions. This study is among the first detailed fluid inclusion studies of gypsum and suggests that fluid inclusions in gypsum can be paleo‐hydrogeologic proxies.  相似文献

This article explores the role of two large European rivers — the Rhine and the Danube — in the structured development of the European territorial system. The water resources of the Rhine river, the tributaries and connecting canals have created the greatest industrial megalopolis on the continent. In this process and under contemporary conditions, the area is connected with the Danube basin by the newly built Rhine‐Main‐Danube canal. As a result, new structures are forming, having the character of an ecological‐economic system. It is in this direction that part of the European territorial system connected with the Danube is developing. As physical‐geographical and ecological factors accelerate economic development and integrate new economic structures, new opportunities arise. With the link to ecological and water resources, development of the Danube as Europe's newest, prospective zone of expansion is predicted.  相似文献

It has been argued that by‐pass roads lead to suburban growth and that the construction of such roads will prompt the planning of industrial and other commercial developments, on the part of the local municipal government. This case study of five by‐pass roads shows that a significant, but limited suburban growth takes place along these roads. Actors who promote development have a greater effect on the planning process than those who resist land development. One exception is the regional authorities who can object to a local plan. The study also shows that most of the local development plans are submitted for approval by the local authorities themselves, either independently or jointly with private developers.  相似文献

Geologic carbon capture and storage (CCS) is an option for reducing CO2 emissions, but leakage to the surface is a risk factor. Natural CO2 reservoirs that erupt from abandoned oil and gas holes leak to the surface as spectacular cold geysers in the Colorado Plateau, United States. A better understanding of the mechanisms of CO2‐driven cold‐water geysers will provide valuable insight about the potential modes of leakage from engineered CCS sites. A notable example of a CO2‐driven cold‐water geyser is Crystal Geyser in central Utah. We investigated the fluid mechanics of this regularly erupting geyser by instrumenting its conduit with sensors and measuring pressure and temperature every 20 sec over a period of 17 days. Analyses of these measurements suggest that the timescale of a single‐eruption cycle is composed of four successive eruption types with two recharge periods ranging from 30 to 40 h. Current eruption patterns exhibit a bimodal distribution, but these patterns evolved during past 80 years. The field observation suggests that the geyser's eruptions are regular and predictable and reflect pressure and temperature changes resulting from Joule–Thomson cooling and endothermic CO2 exsolution. The eruption interval between multiple small‐scale eruptions is a direct indicator of the subsequent large‐scale eruption.  相似文献

The interactions of nature and society are intimately reflected in the degradation of the vast, yet diverse, landscapes and ecosystems of arid western China. The development of agriculture, especially irrigation, has altered rivers, soils and ecosystems so much that major ecological rehabilitation and restoration efforts have been needed since 1950. The catchments of the Tarim River in southern Xinjiang (the Tarim Basin) and of the Black River (Hei He) in Gansu Province and western Inner Mongolia provide examples of the benefits, difficulties and conflicts involved in dryland water management. In the early stages of the human development of these catchments, agriculture depending on irrigation using water from these inland rivers was encouraged. The over‐exploitation of these water resources led to such ecological problems as desiccation of lakes, drying out of rivers, degradation of soils and vegetation and lowering of groundwater levels, with consequent environmental and economic impacts. Since 1990 several high‐cost, national projects to re‐establish ecosystems have been initiated. Water is now released from dams in the headwaters of the rivers in order to restore water flows to the dried out lake basins. Such schemes have inevitably led to social problems and difficulties for the people who depended on the water from the dams for local irrigation. The contrasts in adjustments and attitudes over the use of water for agriculture and other economic activities, as opposed to schemes of restoration of ecosystems and ecological engineering, stem largely from two issues; inconsistent provision of information from the scientific community, and differing ideologies, namely environmental protection versus economic development.  相似文献

ABSTRACT We examine the impact of the political trade‐off between rural economic development and environmental quality on the determination of environmental regulations in the U.S. intensive livestock industry. The political economy model, adapted from Fredriksson (1997) , is tested empirically, using state‐level data on environmental regulation of the U.S. livestock sector. We find that state governments respond to greater potential for water pollution with more stringent environmental regulations. Consistent with our political economy model, we also find that states with lower recent growth in per capita income implement less stringent environmental regulations.  相似文献

The countryside around towns is under increasing pressure for development as a result of the centrifugal forces which have characterised the capitalist urbanisation process in the post‐war era. Conflict between pro‐growth and anti‐growth interests is now endemic in many peri‐urban areas. This paper identifies the principal agents involved in the production of the built environment in the urban fringe and presents a detailed analysis of how divergent interests interact to determine the nature of the fringe environment. The research informs academic debate on rural land conversion and provides guidance for decision‐makers charged with management of the urban fringe.  相似文献
