From a national perspective it is unclear whether the continued expansion of urban development seriously affects America's potential food production over the long run. Yet there are clearly regional biases toward conversion of farmland to urban uses and locally important changes in the appearance of the landscape at the rural—urban fringe. Urbanization also generates spillover effects causing the idling of farmland and the shifting from one type of agriculture to another.Land use controls aimed at directly addressing the use of the land may be effective in preventing some conversion of farmland to urban uses but the methods are costly and possibly very complex. Incentives to farmers to keep land in agriculture are generally too weak to be effective in retaining agricultural land in the face of strong urban pressures.This research was supported by a grant from the National Science Foundation (Research Applied to National Needs) to the Regional Science Research Institute.  相似文献

Planning control of urban land use in most of the Australian States is by the planning scheme system and is authorized by legislation based on the English Town and Country Planning Act, 1932. Under this system each planning authority prepares a land use zoning and reservation plan designed to accommodate the forecast urban growth. It then reviews and regulates the proposals for urban development projects as they are brought forward to ensure that they conform to the plan.  相似文献

The speed and scale of urbanization provide serious challenges for governments all over the world with regard to the realization, maintenance, and operation of public urban infrastructures. These infrastructures are needed to keep up with living standards and to create conditions for sustainable development. The lack of public funds and the inefficiencies of public service provision have given rise to initiatives to stimulate private parties to invest their resources in public urban infrastructures. However, private sector participation creates a whole range of new challenges. The potential benefits are countered by concerns about the compatibility of the private sector's focus on short-term return on investment with the long-term perspective needed to realize sustainability targets. On the basis of a review of literature on experiences with private sector participation in urban infrastructure projects, this article identifies governance practices that help or hinder the reconciliation of private sector participation in urban infrastructure projects with the objective to increase the sustainability of the urban environment.  相似文献

Recognition of the deficiencies of traditional ‘blueprint’ approaches to land use and infrastructure planning has led to increased emphasis on management of the process of urban development. Such management should recognize the distributional impacts of decision-making and be responsive to the needs of residents. However, much urban planning activity has been and continues to be gender-blind. In order to redress this deficiency, it is argued that increased understanding is needed of women's economic and social roles in urban society, their exclusion from economic opportunities and decision-making processes, and the discriminatory nature of much legislation. Urban residents’ experience is shaped both by household strategies and by the way in which they are affected by or can affect planning, investment and management decisions made at the neighbourhood or city level. Differing experiences may be related to class and ethnicity, but are also likely to be gender-specific. The potential impact of policy and investment in a variety of sectors of urban development on residents, especially women, is explored. Recommendations are made for a more gender-aware approach to planning for economic activity, land and shelter, public transport and infrastructural and social services, and for specific actions to be taken by both planners and residents.  相似文献

Some realities about sprawl and urban decline   总被引:1,自引:0,他引:1  
Abstract

Many urban analysts believe suburban sprawl has become an important issue because it helps generate two types of problems: growth‐related difficulties like rising traffic congestion, and high concentrations of poor minority households in core‐area neighborhoods. However, a careful regression analysis of measures of both sprawl and urban decline shows no statistically significant relation between these two conditions.

The basic nature of the American urban development process would cause core‐area poverty concentrations even if sprawl were replaced by more compact growth forms. But sprawl does aggravate growth‐related problems. Those problems could be attacked through either alternative overall growth strategies—such as high‐density, tightly bounded growth—or specific anti‐sprawl tactics, such as regional tax‐base sharing and regional coordination of land uses. But no feasible policies are likely either to alleviate traffic congestion much or cause most American regions to abandon sprawl.  相似文献

  • The costs and benefits of inter‐jurisdictional cooperation and how these impede strategic alliances among jurisdictions is an issue of growing importance worldwide. The reason is the potential cost savings, efficiency increase and economic development benefits that can be realized through cooperation. The literature has increasingly mentioned transaction costs as obstacles that mitigate cooperation and as a key component of cooperation costs, which must be outweighed by cooperation benefits in order for communities to perceive advantageous strategic alliances. However, a framework is lacking in the literature for evaluating the implications of transaction costs for inter‐jurisdictional cooperation. This paper develops a framework for evaluating the nature and dynamics of transaction costs and their implications for inter‐jurisdictional cooperation, with an application to land use. A simple cost function model is used to explain the costs and challenges associated with managing coordinated, cooperative or consolidated relationships, and the dynamics of such costs. The analysis highlights the importance of such things as degree of complexity, inter‐party diversity and the relative sizes of collaborating partners. An application to land use cooperation in Michigan suggests that policies to eliminate transaction costs could help reduce the barriers to cooperation of various types.

Urbanization almost invariably accompanies development, and the cities of India and China are experiencing spectacular increases in population. The concentration of millions of people in a small mass creates challenges for public policy, especially in the areas of basic infrastructure, public health, traffic congestion, and often law enforcement as well. In this essay, I discuss five core debates in urban policy, including the optimal degree of federalism, private versus public provision of urban services, optimal land use regulation, appropriate spatial policies, and the use of engineering and economics approaches to reducing the negative consequences of density. None of these debates are close to being resolved, but researchers have managed to generate a number of useful insights in these areas. © 2011 by the Association for Public Policy Analysis and Management.  相似文献

This paper explores the role of monitoring and evaluation in the planning process with reference to urban development projects, especially those concerned with the upgrading of unauthorized housing areas. Monitoring, it is suggested, may be separated from evaluation, which may itself be subdivided into ongoing or formative and ex post or summative evaluation, and definitions of these terms are offered. Potential audiences for monitoring and evaluation research are identified and their interests discussed. Monitoring and evaluation requirements in relation to upgrading projects are then analysed in more detail, in terms of organizational requirements, methodology, and the utilization of findings. The discussion is illustrated with examples of the monitoring and evaluation systems established in upgrading projects in Zambia, Indonesia and the Philippines. Finally, some of the substantive issues which are relevant to the evaluation of upgrading are outlined and briefly discussed. These include the efficiency of project implementation, progressive development and self help construction as a means of increasing the low cost housing stock, community participation in planning and implementation, affordability and project impact.  相似文献

The basic question posed is: How can a model of a major urban and/or regional subsystem (e.g. housing, health, education or transportation) be developed to maximize its utility for public policymakers? A technique to be used in the evaluation of the utility of such a model is presented. The proposed technique involves the construction of autility evaluation matrix. In constructing this matrix it is necessary to identify the following: (a) the potential users of the model, (b) the actions open to these users, and (c) the consequences which are considered by the users when evaluating alternative actions. Utility testing should become as commonplace and important as validity testing. The utility evaluation technique described in this paper is hardly the required test, but at least it can be viewed as a step in the right direction.  相似文献

Abstract

Referring to the short-term survival of new progressive governments, ‘progressive setback’ has been a remarkable political phenomenon in many East Asian countries during the recent decades. Regarding this phenomenon's background, this paper investigates why and how urban citizens challenged their progressive governments in Thailand, South Korea, and Japan. First, this paper argues that the progressive setback across East Asia reflects the difficulty progressive governments faced in overcoming the legacy of longstanding conservative regimes, which had locked urban citizens into specific modes of subsistence. The progressives invoked the protest of urban populations as their new socioeconomic policies undermined these populations’ traditional basis of subsistence. Second, an investigation of the primary modes of urban subsistence in each country makes the cross-national comparison of progressive setback possible. Urban middle classes in Thailand, as an exclusive group incorporated into the mainstream political economy, engaged in a fierce contest with a progressive government that denied their privileged status in Thai society. In Korea, the self-employed turned to the conservative party since market restructuring programs of the progressive government made it difficult for these self-employed to maintain profits and sustain their livelihood. Finally, Japan's urban workers could not welcome the welfare expansion of the new labor-friendly government, because this class was too dependent upon wage incomes to agree with the consumption tax hike that welfare expansion required as its precondition. This paper implies that the old habits of urban citizens are an important hurdle for East Asia's progressives to overcome.  相似文献

Of late, participatory forestry management, more popularly known as ‘social forestry’ (SF), has acquired great significance in Bangladesh as a strategy for both forest resource management and rural development. However, research on the contextual factors such as social relations, institutional structures, forest policies and land tenurial arrangements which regulate SF's performance in the field has been limited. Land ownership and tenurial arrangement is one crucial factor which has remained virtually unexplored in the context of Bangladesh SF. This article examines the land use and tenure arrangements in selected SF projects in Bangladesh. It focuses on the perceptions and choice of the SF farmers regarding land ownership, tenure and use; implications of central land tenurial policy on farm productivity and farmers' motivation; and also on the difference between farmers' land use choice and the assumptions of the SF planners. It shows that land tenure is a complex issue for SF. Although tenurial security is a major motivating force for farmers, providing permanent land ownership alone has little impact on farm productivity or on the growth of collective effort among SF farmers. Farmers need institutional assurance and support (especially from the government) to fully utilize the potential rights and benefits associated with such ownership. © 1998 John Wiley & Sons, Ltd.  相似文献

It is argued, with reference to urban local government in Zambia, particularly in Lusaka, that recent debates on the form and functions of the national state in Africa may be used to illuminate the working of the urban local state. Available evidence on the class interests represented in the urban local state is reviewed, and these interests and their actions with respect to personal accumulation and political clientelism are found to be similar to those found at the national level. The urban local state in Zambia performs functions similar to those which have been revealed by analyses of other countries, although the nature of these functions, and the extent to which they are successfully performed, is influenced by the political and economic context, the institutional framework and especially the constraints imposed by central government on local autonomy. The changes proposed in the 1980 Local Administration Act are outlined, and a preliminary assessment made of the extent to which they are likely to change the form and functions of the urban local state.  相似文献

Previous research has extensively analyzed the role, and indicated the importance, of network management for the functioning and performance of public or governance networks. In this article, we focus on the influence of boundary spanning actors in such networks—an aspect less examined in the governance network literature. Boundary spanners are considered to be important for governance network performance. Building on the literature, we expect a mediating role of trust in this relationship. To empirically test these relationships, we conducted survey research (N = 141) among project managers involved in urban governance networks: networks around complex urban projects that include the organizations involved in the governance process (the formulation of policies, decision making, and implementation) in these complex projects. We found a strong positive relationship between the presence of boundary spanners and trust and governance network performance. The results indicate a partially mediating role of trust in this relationship. Furthermore, we found that these boundary spanners originated mainly from private and societal organizations, and less from governmental organizations.  相似文献

Truthfulness, the norm of science, is etymologically related to trust. Both concepts are related to ‘tree’, as a symbol for grounded knowledge, for differentiation (the tree of knowledge), for uprightness and reliability (Searle, 1995). Truthfulness generates trust. Trust generates community. The land politics and trust project in South Africa (Askvik and Bak, 2005) investigated how trust relations intervened within and between government institutions engaged in redistribution and management of land. It enquired into trust relations between the land state and stakeholders in land. It assessed how the new ANC‐controlled state intervened into the relation between market‐oriented urban industry and subsistence‐oriented livelihoods on communal land. Could that intervention explain the slow pace of land redistribution? The field work was done in the Northern and the Western Cape provinces. A hypothesis is that unconditional personal trust across institutional boundaries is a condition for post‐colonial, post‐liberation community building. In 2001, aspects of political democracy were in place. Trust relations between government institutions and to stakeholders in land varied, but were limited. Trusted mediators between the institutions, across cultures, were few and far apart. Subsistence‐oriented livelihoods on communal land were there to be transformed to commercial farming. The three‐step Government strategy, growth in the urban economy, commercialisation of rural subsistence production and rural welfare from the urban surplus, augmented separation, disbelief and distrust.

Rising global prices for agricultural commodities have led to the inflow of capital to rural economies and to transfers of land ownership to new agricultural operators (NAOs) in developing and post‐Soviet countries. How capital inflows affect rural communities is often explained with the variable of institutional strength, an explanation aligned with the good governance approach to economic development: Capital inflows have positive developmental effects, if strong domestic institutions vet land deals and regulate NAOs. Contra the focus on institutional parameters as exogenous variables, this article highlights the role of political projects in shaping local outcomes and driving institutional change. Evolving political priorities are important to understand domestic rural transformations because they lead to interventions that privilege some actors as agents of change, while others are sidelined—hence transforming local economies. This theoretical suggestion is based on a study of Russia's rural transformation that followed a significant influx of capital.  相似文献

The purposes of this essay are to describe how federal research and development policy has altered authority relationships and to suggest a new concept of legitimacy in accord with the changed conditions. Research and development (R and D) creates an indeterminate future. Thus, the politics of research and development incorporates an apparent contradiction : political leadership demands that jobs be done which require creative and unpredictable actions on the part of private organizations, while it also demands that contractors be held responsible for fulfilling goals efficiently, avoiding deleterious secondary consequences, and refraining from abuses of power. The paradox can be resolved by creating norms of responsibility that allow for judgments on how a job is done rather than what is to be done. New institutions for technological assessment to check on unintended consequences of projects and citizen review boards to estimate the quality of life engendered by projects may provide such norms of responsibility.  相似文献

The Garrison Diversion Unit (GDU) was authorized by Congress in 1965. It is one of the largest and most expensive public works projects ever undertaken in the United States. When completed, it may become the last major federal irrigation scheme constructed in the west. Its principal purposes are: (1) to irrigate some 250,000 acres of arable land in North Dakota, (2) provide water for municipal and industrial use in fourteen communities, and (3) enhance recreational opportunities and fish and wildlife management programs within, and adjacent to, the canals and reservoirs resulting from its construction. The project is to be financed by hydropower sales from Lake Sakakawea, created when Garrison Dam was completed in 1956.1 Concerted litigation, Canadian opposition, and federal budget cuts have sharply reduced the size and scope of GDU since 1984. Its irrigable acreage has been reduced by over 50%, a principal feeder reservoir has been eliminated, and provision of municipal and industrial water delivery has been moved from second to first priority by a Congressional commission. The GDU controversy illustrates the consequences of the lack of a coherent environmental ethic guiding American natural resources policy. These consequences are two-fold. First, although GDU's impacts extend to Canada, there is little agreement between the U.S. and Canada over what values should guide transboundary water resources development. Second, American beneficaries of the project define its need in pre-emptory terms - i.e., as compensation to an entire region for losses of land associated with the original construction of Garrison Dam. Opponents, meanwhile, argue their case in meliorative terms - i.e., that the costs to society of building additional water projects are not outweighed by their benefits. While both views have some merit, neither view can alone encompass the range of social, economic, and environmental consequences of complex river basin development.Operated by Martin Marietta Energy Systems, Inc. for the U.S. Department of Energy under Contract No. DE-AC05-840R21400.  相似文献

内地农村土地流转何去何从?——重庆实践的启示   总被引:2,自引:0,他引:2

基于对重庆农村土地流转实践的调研,本文认为,城市规模扩张(城市化)、农民的非农就业和农业规模经营要求是土地流转的动力。在不同形式的土地流转过程中,土地产权仍不够明晰、农民惧怕风险和社会保障不健全是土地流转的主要阻碍因素。在利益分配方面,政府对土地流转的过度介入对农户的权益保护不利,急需完善市场和健全法制。同时,重庆的实践说明,要在城市化进程中推进土地流转,实现城乡统筹发展,关键是靠农业用地转为非农业用地过程中产生的土地增值收益。因此,建设用地指标的跨地区流转和劳动力的跨地区流动是未来可试验的方向,但应实现土地与户籍制度改革的联动,这是有利于统筹城乡和区域发展的举措。  相似文献

The individuals and circumstances involved in the creation of the first graduate urban studies program in Venezuela are recalled, beginning with the odernization of Caracas under the impulse of President Antonio Guzman Blanco, elected in 1870. Guzman Blanco converted himself into Venezuela's first urbanist with the establishment of organizational frameworks and completion of massive public works projects, which were based largely on the urban models of the US and Europe. Engineering and public health were consolidated as the two most influential sources of professional competence for guiding urban development. By the mid-1930s, growth fueled by petroleum revenues was causing rapid urbanization, and it became apparent that trained professionals able to manage the increasingly complex tasks of urban planning were in short supply. A new surge of modernizing construction began in 1936 and led to a cooperative arrangement with a French firm, whose personnel were to be required to train Venezuelan engineers for future service in urban planning. An influx of refugees from the Spanish Civil War and the increasing influence of urban planning processes in the US were also observed. The National Commission on Urbanism was created in 1946 as a dependency of the Ministry of Planning to facilitate public administration of the development and control of cities. Throughout the period, a debate was underway on the need for a multidisciplinary approach to urban planning versus a primarily architectural or engineering approach. In 1957, some consensus was reached on the need for urban planning to be viewed as more than a speciality of architecture. A framework was developed for a graduate program in 1969 in the Central University of Venezuela. The National Commission on Urbanism was disbanded in 1957, largely because of its excessive focus on architecture to the exclusion of other disciplines relevant to the urbanization process.  相似文献

The strengthening of alliances through cooperative military activities is a long-established tradition for land, sea and air forces. With the rise of spacepower over the last 50 years, and the growing number of spacefaring and space-using nations, military space programs provide new opportunities for military-to-military cooperation. Military space programs often represent the most technical and secretive of capabilities and there may be risks in sharing the inner workings of these capabilities, even with trusted allies. Is there a way to share the benefits of these strategically and tactically important capabilities in a manner that enhances the peace, justice and security of all stakeholders? Many nations around the world are answering ‘yes’ to this question as they enter into agreements on cooperative space projects for commercial, environmental and military security. More and more they are using their space programs to realign the old balance of power and create new common interests. As the number of spacefaring nations increase and the number of space users grow around the globe, the traditional space powers, such as the United States, need to reconsider how to integrate military space cooperation in their strategies of strengthening alliances and building common interest.  相似文献
