The Beijing-Tianjin-Hebei (BTH) region is an important engine for China’s socioeconomic development. Timely and effectively assessing constraint factors of resources and environment is of great significance for the sustainability assessment and the sustainable development of this region. However, comprehensive assessment research considering key resource and environmental constraints are still lacking. In this study, therefore, the limiting factors of resources and the environment in the BTH region were assessed based on the framework of landscape sustainability science. First, we chose five limiting factors, including topographic condition, geological environment, water resource, land resource, and atmospheric environment, to assess the constraints of resources and the environment using the single-factor evaluation method and the multi-factor comprehensive evaluation method. Based on the results, we divided the whole region into five subregions, i.e., the ecological conservation subregion, the geological disaster subregion, the water resource scarcity subregion, the atmospheric pollution subregion, and the cropland protection subregion. The results revealed that the northern BTH region was highly constrained by topographic conditions, the central BTH region was strongly constrained by geological environment and water resources, whereas the southern BTH region was constrained mainly by land resources and atmospheric environment. In addition, water resource was the main limiting factor for regional population growth and economic development. In 2010, the water resource scarcity subregion had a total population of 39.59 million, an urban population of 76.90%, and a gross domestic product of 2 455.57 billion yuan. We argue that the sustainable development of the BTH region should explicitly consider the resource and environmental limiting factors, implement land use optimization according to local conditions, maintain multiple land use types and diverse management strategies, based on the perspective of “strong sustainability”, so as to promote the regional sustainable development.  相似文献

Socio-economic factors influencing sustainable water supply in Botswana   总被引:2,自引:0,他引:2  
Lado C 《GeoJournal》1997,41(1):43-53
The paper examines the socio-economic and political issues of sustainable water supply in Botswana. It pays particular attention to the actual and potential role of economic instruments. Water consumption occurs both in a market and non-market contexts (producer = consumer). Due to rapidly increasing water demand and the fact that the "easy" solutions to increase water supply have largely elapsed, Botswana is concerned with water shortages which may hamper peoples basic needs and industrial development in the future. Other sustainability concerns relate to the environment (pollution), social factors (equity and affordability) and economic considerations (cost recovery and efficiency). Prices, costs and the value of water are instrumental in striking a compromise between these goals. Trends in pricing and their relationship with costs and resource value are presented, and the impact of prices and subsidies on water demand and supply reviewed in order to assess their contribution towards a sustainable equilibrium. There is a substantial scope to improve the performance of economic instruments such as price subsidies and tax relief. The long-term marginal costs calculated in the Botswana National Water Master Plan contribute to prices approaching the costs of water production, but it excludes the environmental considerations. Resource scarcity is partly reflected where it increases the water supply costs; the indirect use and non-use values and external impacts are not incorporated in the water charges. Higher prices would increase the economic feasibility of water recycling and water harvesting and generate investment capital needed for the expansion of the water supply systems. Government subsidies may discourage efficient resource use. It is generally concluded that there is need for greater emphasis on re-use of waste water and control of the demand by harmonizing fees or tariffs between urban and rural areas as far as non-essential use is concerned; and provide more incentives for large-scale consumers to increase water use efficiency and sustainability.  相似文献

This paper analyzes the transformation of China’s advertising industry as a result of China’s economic reforms and the globalization of the advertising industry. Spatially clustered in the city-regions of Beijing, Shanghai and Guangzhou, the industry has been structurally and operationally integrated with the global advertising giants, as well as developing local strategies to attract the interest of local consumer markets. While the entry of global multinational advertising businesses has compelled China’s advertisers to accept and adapt to the industry’s globalized institutions, standards, operational procedures and corporate culture, the transformation of China’s advertising industry is best understood as a consequence of the interaction between globalization and localization.  相似文献

Baldacchino [Baldacchino, G., 2002. Jurisdictional self-reliance for small island territories: considering the partition of Cyprus, The Round Table, 365, 349-360] has argued that the ‘troika’ of smallness, insularity and peripherality may incline island peoples (rather more than mainlanders?) to question the effects of economic globalization and be especially disposed to innovative approaches to development. He views jurisdictional capacity as integral to that task. Much of the literature on such issues relates to island nations, but this work focuses on Australia’s smallest and only island state of Tasmania, and thus on a sub-national jurisdiction. In what follows I explore the effects of an attempt to enrol Tasmanians in the creation and stabilization of a ‘2020 vision’ meant to be global in its reach, to focus on the particular strengths of the island state, and be innovative in advancing sustainable development. Known as Tasmania Together, the 20-year strategic vision outlines diverse economic, social and environmental goals assembled over two years via widespread consultations with the island’s communities of place and interest. For a time Tasmania Together generated significant debate about what it means to be an island people, and whether and to what extent Tasmanians’ future will be secured through economic globalization or localized endeavours premised on sustainability principles. Important to Tasmanians as well as to island studies, these rhetorics of social and spatial engagement also have salience beyond the borders of the island state, highlighting larger questions about the technologies of governmentality, agency and the performance of identity.  相似文献

Ghana is endowed with surface and ground water resources. These resources prior to the colonial era were managed by traditional societies through various conventional methods embedded in their cosmovision. However during the colonial and postcolonial regimes, in response to climate change, economic globalization, and population pressure, there has been a conscious shift from customary water management systems towards paradigms cast in the contemporary mould (legislation, policies, and institutions). These modern approaches have been shown over the years to be insufficient in ensuring water sustainability. This insufficiency manifests itself in the increasing water scarcity through anthropogenic-induced water resources degradation and severe climatic variability. Using content analysis, this paper reviews this transition, first to fully understand the intricacies of the evolution and second to draw lessons for better water resources management in Ghana. This paper contends that although Ghana’s water related institutions, laws, and policies are undergoing significant reforms, implementation and practice remains embedded in weak ecological modernization (EM). Institutionalizing a narrow conception of EM will only perpetuate ‘organized irresponsibility’ and permit the continued production of ecological problems, leaving open the question of whether modernization is compatible with ecological sustainability. Though customary water management approaches are not entirely devoid of limitations, simply branding them as obsolete may obviate an important vehicle for water sustainability. In the spirit paradigmatic complementarity, ecosystem-friendly indigenous approaches must be integrated with contemporary management systems for the long term goal of sustainability.  相似文献

States employ international economic institutions as formal mechanisms in resource related conflict management. It is little known that states incorporate water resource management treaties in regional trade agreements (REIs) to jointly manage (1) the multifaceted use of rivers and (2) the territorial implications of rivers as borders. Both can lead to political tensions. I evaluate institutional effectiveness, through REI institutional design, in militarized interstate conflict. The role of trade institutions in geo-politics is a broad theme addressed. African dyads, REIs and conflict from 1950 to 1996 are the focus. I test the liberal hypothesis that institutions diminish the likelihood of militarized interstate conflict. Findings suggest allies that share memberships in REI water treaties with provisions for territorial boundary issues are more likely to fight than are other states. This relationship is weak, however, lending support to realist claims.  相似文献

While geographers have increasingly focused on how global commodity and production networks create new ‘geographies of responsibility’ there has been little empirical work considering how responsibility is worked into management systems and social activism in such networks. Drawing on literature from global production networks, geographies of responsibility and other literatures, this paper explores the dynamic and contested ways in which concepts of responsibility can play a role in network regulation. Both foreign direct investment and commodity networks (here referred to as ‘global production and investment networks’) are subject to complex negotiations and compromises involving corporate social responsibility and sustainability initiatives as well as shareholder activist, human rights, labor, and environmental activism. This is illustrated by reference to conflicts in Canada over Alcan, Inc.’s investments from 1993 to 2007 in the Utkal Alumina Project in Orissa, India. The project involved significant socio-environmental conflict. In Canada, Alcan’s investment was met by civil society campaigns that tested the company’s commitments to sustainability and corporate social responsibility. The case study suggests revising theories of geographies of responsibility. While foreign direct investment can create new relationships between distant others, these are fluid and contingent and not necessarily desirable. Rather than see networks as a source of responsibility we should work to ensure that the relationships that networks foster be structured to ensure our deeper values are respected.  相似文献

In accordance with Senegal’s decentralisation policy, important forest management tasks, including the right to allocate charcoal production rights, have been transferred to rural councils. This paper investigates the impact of these institutional reforms on charcoal production practices using the environmental entitlement framework developed by Leach et al. [Environmental entitlements: dynamics and institutions in community-based natural resource management. World Development 27 (2) (1999) 225]. The councils have not been able to turn their new endowments into entitlements because they lack sufficient strength and legitimacy. Informal institutions, notably the coalition between merchants, state agents and village chiefs, continue to run the charcoal business and are hardly affected by decentralisation efforts. Most rural people, especially those relying solely on agriculture for sustenance, do not benefit at all from the charcoal trade. They do suffer from the environmental costs it brings with it, however. Although tensions between pro-exploitation actors and pro-conservation actors are evident, the pro-exploitation actors’ firm grip on the informal institutions will probably lead to a prolonged subversion of the laws that seek to enhance local control and to sustain the forest.  相似文献

This paper reports the results of our research, conducted from June to August 2004, on the community-based conservation project in Mahenye, Zimbabwe. Previous studies have described this project as a model example of Zimbabwe’s CAMPFIRE program. We explore the project’s recent performance within the context of the country’s post-2000 political and economic crisis and address the implications of our findings for arguments supporting devolution of authority for natural resource management to the community level. These issues are related in that calls for devolution are at least partly contingent on the demonstrated capacity of local institutions to manage projects in the community interest despite difficult circumstances. In our research, we found that outcomes in Mahenye have deteriorated sharply from conditions described in earlier studies. We found further that local failures of leadership combined with the withdrawal of outside agencies responsible for oversight and assistance may be more to blame for this decline than the ongoing national turmoil. Our results suggest that even in apparently successful conservation and development projects, local participatory decision-making institutions are fragile and require continuing external support. Consequently, we argue for caution in promoting full devolution of authority to the community level without safeguards to maintain good governance and adequate capacity.  相似文献

Understanding people’s willingness to participate in projects and programmes of payments for ecosystem services (PES) has not been a key analytical concern of the scholarly literature around this new field of environmental policy and practice. This paper analyses participation in four communities benefiting from payments for biodiversity and carbon fixation in Mexico, and contrasts the results for each case with neighbouring communities that do not receive payments. We take a holistic approach that accounts for procedural rules, actors’ interactions, institutions and values, and individuals’ characteristics. We show that the nature of PES rules and the effectiveness of communication with government officers and NGOs influence resource managers’ ability and willingness to participate. We highlight community size, resource managers’ ability to diversify livelihood activities and local perspectives on the conservation of common forests, particularly sacred values and intergenerational concerns on forest conservation, as critical participation drivers. This analysis provides insights on why and how these new institutions may be attractive for some resource managers and permits to draw some recommendations for the future design of PES projects and programmes.  相似文献

Analyses of sustainable design and commodity networks often make a priori assumptions about the capacity of markets to provide solutions to environmental problems; and have a tendency to celebrate local scales of action. This paper offers a contrasting account, in which the national state sought to carefully manage scarce natural resources and to ensure equitable consumption at a time of deep crisis. We utilise the historical example of the British wartime Utility furniture scheme in order to draw out three lessons for sustainable and equitable environmental practice. First, we argue that national states do not simply provide an institutional backdrop to sustainable production but rather can act as important organising agents. Second, the paper emphasises that sustainability is best achieved through interventions across a commodity network, beyond simply modifications to a single node such as design. Finally, we underscore the value of ‘pragmatic centralism’ in environmental decision-making, calling attention to the collaborative practices that underpinned the scheme. The example of Utility’s adaptive responses—borne out of crisis, scarcity and shortage during wartime—offers much that is of intrinsic interest to current concerns about resource consumption and the drivers of sustainability in commodity networks.  相似文献

Different types of vegetation found in local environments are of value to rural livelihoods of many African households. However, the dominant way of expressing this value, which is mainly through economic valuation studies, is potentially limiting this knowledge’s usefulness in policy and research, due to the inability to present full picture. Using literature review and insights from field work, the paper argues that realized and notional values of vegetation to rural livelihoods are socially constructed and contested, and - in addition to understanding local livelihood context, which include social difference, and ecological dynamics - a focus on social institutions as terrains of negotiation is crucial. This means that resource value in rural livelihoods can be realized through contested and negotiated access arrangements that are mediated by complex institutions at local and external levels.  相似文献

The evaluation of agricultural sustainability status helps in identifying specific indicators that constrain the achievement of sustainable agriculture. The agricultural sector in Egypt is facing major sustainability constraints such as scarce land and water resources, environmental degradation, and rapid population growth as well as institutional arrangement including land tenure and farm fragmentation, agricultural administration, lack of infrastructure, and credit utilization and high interest rates. This study aims to evaluate the agricultural sustainability in some areas in Kafr El-Sheikh governorate, north of the Nile Delta; the international framework for evaluating sustainable land management was used for realizing this objective. The map of the physiographic soils of the studied area was produced depending upon Landsat ETM+ images analysis; the results indicate that the area includes three main landscapes, i.e., alluvial, lacustrine, and marine plains. The characteristics of productivity, security, protection, economic viability, and social acceptability in the different mapping units were assessed. The obtained results show that the studied area includes two different class types, the first are the lands that are marginally below the requirement of sustainability and the second are those lands that do not meet sustainability requirements. The former class is represented by the physiographic units of alluvial plain, whereas the latter class is represented by the physiographic units of the lacustrine and marine plains. The sustainability constrains in the studied area are related to the soil productivity, economic viability, and social acceptability.  相似文献

As an approach to development, many see capitalism as reaching across an enormous range of scholarly domains and political interests. For some time geographers and others have begun to conceptualize capitalism as less of a system of intrinsic economic logic and more a collection of social and discursive relationships. By bringing capitalism into the “discursive world” these commentators and others have provided the theoretical ground for an exploration of alternative economic forms, especially those that are more socially and ecologically just. This paper makes an argument for putting sustainable development through the same theoretical scrutiny. Drawing on examples from the US we recruit the concept of “actually existing sustainabilities” from Altvater’s concept “actually existing socialisms” as an entry point to this conversation. Our purpose is to show that the potential for sustainability in the US exists in current local policies and practices if we rethink how we frame it.  相似文献

Evident mismatches exist between the demand and supply of water in many countries particularly in the semi-arid and arid worlds. The resulting food gaps which concern both the national governments of these countries as well as the international agencies which extend assistance to them, appear at first sight to pose challenges beyond the economic and political capacity of peoples and institutions to make the necessary adjustments. The institutions with responsibility for the allocation and planning of water use at international, national and local levels do not seem to be robust enough, or informed enough, to provide the necessary leadership to ensure that scarce water is used sustainably.It will be argued that despite the great difficulties which governments and users face in coping with the need to manage water so that it brings a sound return, as well as according to principles of equity, safety, and ecological sustainability, everywhere there are examples of conflict over water being avoided. And while the avoidance of conflict can in many cases be calculated to have been at a cost to the environment, nevertheless, to date conflict of a hot nature has been avoided. Case studies from a region seen to have the worst water resource future outside the industrialised world, the Middle East and North Africa, will be discussed which exemplify the numerous strategies adopted by countries in their various ecological, economic and political circumstances. A fortunate few governments have substituted oil capital for water while others have filled the food gap, which is generally an expression of the water gap, by ceding economic and political autonomy.  相似文献

Though the concept of sustainable development originally included a clear social mandate, for two decades this human dimension has been neglected amidst abbreviated references to sustainability that have focused on bio-physical environmental issues, or been subsumed within a discourse that conflated ‘development’ and ‘economic growth’. The widespread failure of this approach to generate meaningful change has led to renewed interest in the concept of ‘social sustainability’ and aspects thereof. A review of the literature suggests, however, that it is a concept in chaos, and we argue that this severely compromises its importance and utility. The purpose of this paper is to examine this diverse literature so as to clarify what might be meant by the term social sustainability and highlight different ways in which it contributes to sustainable development more generally. We present a threefold schema comprising: (a) ‘development sustainability’ addressing basic needs, the creation of social capital, justice and so on; (b) ‘bridge sustainability’ concerning changes in behaviour so as to achieve bio-physical environmental goals and; (c) ‘maintenance sustainability’ referring to the preservation - or what can be sustained - of socio-cultural characteristics in the face of change, and the ways in which people actively embrace or resist those changes. We use this tripartite of social sustainabilities to explore ways in which contradictions and complements between them impede or promote sustainable development, and draw upon housing in urban areas as a means of explicating these ideas.  相似文献

With over 40% of the water supply of Western and Eastern Europe coming from urban aquifers, efficient and cost-effective management tools for this resource are essential to maintain the quality of life. However, the increasing concerns about the environmental impacts of water projects and their increasing economic costs mean that traditional planning concepts, which assume unlimited supplies of potable water, must be questioned. This includes the source of the water supply and its appropriate use. Urban transport systems and the provision of water have been identified as the most critical factors that determine the future of cities in this century. The objective of an interdisciplinary research project presented in this paper is to identify and develop systems and technologies and integrative processes and analytical tools, which are commercially valuable, scientifically robust and which improve the cost effectiveness of urban water services, in line with the programs vision of ecological sustainability. As part of this program, a software tool has been developed to estimate the water flows and contaminant loads within the urban water system. This paper presents first modelling results of water and contaminant flows through the existing urban water, wastewater and stormwater systems, from source to discharge point.  相似文献
