As economic growth centres, the Southeast Asian cities feature high population pressure, unsustainable land use, environmental degradation, and large ecological footprints. It is difficult to manage environmental health and basic services for urban dwellers, and ensure optimum flow of ecosystem services in the context of rapid, unplanned, and haphazard urbanization. These challenges are particularly multifaceted in the developing countries of Southeast Asian region. This study, based on secondary sources, adopted multidisciplinary lenses, such as geographical information systems, socio‐economic perspective, and sustainability science to examine the population situation, land use change pattern, and drivers of environmental degradation in the Southeast Asian cities as well as the Dhaka megacity, and brought forth a fresh perspective to look into contemporary urban ecosystems, population dynamics, environmental health, and sustainability. It also focused on identifying the commonalities among the cities under study to create a common understanding towards promoting collaborative urban development. This study shows that the urbanization process in the Southeast Asia region is taking place mostly in an unplanned and haphazard manner. With little concern for nature, life‐supporting ecological systems, and the environment, urban spatial growth continues unabated. The data surveyed and discussed in this paper shows that the current style of urbanization in Southeast Asia can best be called unsustainable. The findings also suggest that the general wellbeing and welfare of the current and future generations in Southeast Asian cities as well as in Dhaka is at risk. The paper recommends concerted efforts towards making the urbanization process sustainable, including better urban planning, policymaking, and international and regional cooperation.  相似文献

With the accelerating urbanization, ecological environment of the city has attracted increasing attention, so the resulting problems have become key research focuses in all countries. Against this background, urban agriculture has been applied as one of the effective approaches for relieving urbanization. From the perspective of industrial form of urban agriculture, planning models of urban agriculture were explored, industrial form and planning model of Chengdu urban agriculture were analyzed to forecast its development prospects. Multi-dimensional development, and sustainable development measures were given to guarantee the sustainable development of urban agriculture.  相似文献

City is a spatial synthesis which consists of various buildings and urban opening space.With the developing of the urbanization,the urban planning will directly influence the sustainable development of a city,and the optimization of the urban zone pattern is the main section of the urban planning.The urban opening space is the main part of the urban landscape with important eco-function.Due to its flexibility,the urban opening space is becoming the object of the urban landscape pattern.In this study,some ecological problems during urban development were discussed,and a series of strategies of urban opening space pattern optimization have been put forward based on landscape planning theories.  相似文献

The advancing global urbanization puts great pressure on the society and ecosystem, especially in developing countries. Reasonable land-use policies adapted to local conditions are the key issues to prevent disordered urban expansion. Multi-scenario simulation provides a new perspective for differentiated policy formulation based on regional heterogeneity. Regarding the Shaanxi Province, a rapid urbanized area with high spatial heterogeneity in western China, as the study case, we tracked its past land-use changes and predicted the characteristics of urban expansion using the Future Urban-Regional Environment Simulation model. We found that (1) during the past 35 years, built-up land evidently increased accompanied by the loss of cropland, grassland, and unused land. (2) The urban expansion mainly will occur in the areas with flat terrain under three scenarios. (3) The urban expansion will transit into the “requiring land from mountains” pattern in the future, which means that it will gradually spread to areas with higher slopes. (4) Differentiated and optimal development patterns are proposed for different subregions by accounting the loss of ecosystem service in the procedure of urban expansion. This research can help local governments formulate differentiated future macro control of territorial spatial planning to optimize subregional land development.  相似文献

农地城市流转驱动力与农地保护研究   总被引：1，自引：0，他引：1  
无论在发达国家，还是在发展中国家，农地城市流转现象是其实现工业化和城市化所必须付出的一种代价，已经成为经济发展和城市化、工业化进程中的一个普遍现象。人多地少的国情决定我国农地保护的重要性，但是对处于城市化的加速发展阶段的中国，农地流转必将会持续一段时间，可见，我国农地保护面临的形势不容乐观。本文在他人研究的基础上，认为农地是在地方政府、村经济集体、农民、企业以及居民几大动力主体的相互作用下，在制度缺陷、经济增长、区位状况、城市化以及价值观念驱动力的共同作用下，不断地向城市转移的。最后，提出了保护农地，必须树立科学发展观等对策。  相似文献

In the Mekong Region, the Asian Development Bank and partners have promoted economic corridors as a way to achieve regional economic integration and growth. This study evaluates how a transboundary policy narrative of shared prosperity around the East–West Economic Corridor programme emerged, and then how it was elaborated and used, taking a set of border policies of the government of Thailand as cases. For two decades the shared prosperity narrative has been used by a coalition of elite actors to support a programme of investments in road infrastructure, as well as to push for agreements on trade, border logistics, investment and tourism. The shared prosperity narrative has helped maintain support for the programme despite its failures to meet projections and expectations. Although criticised by civil society and experts from time to time, no coherent shared counter‐narrative emerged. Policy elites in Thailand have used the transboundary narrative to justify investments in special economic zones, and transport infrastructure near the border and inside neighbouring countries. Thailand has also reproduced the narrative in support of efforts to bolster tourism cooperation, and negotiate cross‐border trade and logistics agreements. Roads and bridges have been built, underlining how discursive practices have material consequences and reinforce the narrative.  相似文献

Abstract: It is increasingly recognised that both formal and informal institutions could be important variables in explaining the diversity of capitalist systems. However, less is known about the relative importance of regional institutions for regional economic activity and regional development, especially in developing countries. This article analyses the relative importance of regional institutions to regional capitalist systems in Southeast Asia, using the comparative institutional approach of ‘business systems’. Two comparisons are made that enable an analysis of the relative importance of regional institutions: one between two regional economies in the same country (Cebu and Negros Oriental in the Philippines) and one between two bordering regional economies in different countries (Satun in Thailand and Perlis in Malaysia). We investigate four sets of economic institutions: the extent of alliance coordination of supply and demand, the extent of collaboration between competitors, the extent of alliance coordination of sectors and access to finance. The results suggest that regional economic institutions are stronger in agricultural areas with relatively weak national economic institutions and that the presence of strong and enabling regional economic institutions is one of the factors that lead to taking advantage of favourable agricultural conditions, to economic growth and, ultimately, to catching up.  相似文献

With the aggravation of congestion, pollution, and other negative externalities generated by continued urbanization, polycentric strategies have gradually become one of the main urban and regional spatial strategies. It remains unclear, however, whether the polycentric structure is conducive to regional coordinated development. This study examines these issues using China's urban agglomerations (UAs) as a sample. The Prolonged Artificial Nighttime-light Dataset of China (PANDA) was used to measure the polycentric structure. The results of the nonparametric identification of sub-centers show that almost all of China's UAs exhibit multiple (sub)centers, and the number of (sub)centers in most UAs has increased from 1992 to 2020. Empirical analysis shows that a polycentric structure is beneficial for narrowing regional disparities within the UA, and the narrowing effect of the polycentric structure on regional disparities increases as the distance between centers increases. Furthermore, a polycentric spatial structure is more conducive to the economic growth of small cities in UA, thereby promoting the coordinated development of regions within UA.  相似文献

Economy is a major force in determining the hierarchy of urban system. As regional economy globalizes, urban systems in many countries are making their transition from the scale-based hierarchy to the networked system, while that in China still maintains an administrative stratification. The paper discussed the triumph of Baigou Town in the East Baoding Sub-center Campaign. It significantly shattered the administrative hierarchy of the urban system in China, which owes largely to the new type of economical development, i.e. government-led fixed assets investment and real estate development, as demonstrated in the urban expansion. Under the pattern of "territory" logic, spatial planning not only lost efficacy, but also stimulated bottom-up over development in local areas. The paper recommended foreign action- and collaboration-oriented urban planning theories, and that the absolute top-down spatial blueprint planning must be abandoned, and a harmonious synergy of planning roles, work content and methodology be facilitated.  相似文献

Districts of Chongqing is selected as the study area, which has a rapid rate of urbanization and eco-environmental pressure. The fundamental data of this study is the remote images and urban planning images of Chongqing city in 1988, 1993, 2000 and 2007. After data processing by RS and GIS, model calibration is applied to obtain the best parameters for the SLEUTH model. Then, the SLEUTH model is used for the simulation of the urban growth over the past 20 years. On the basis, the SLEUTH model is applied to predict the situation of urban expansion of the region in the next 10 years. The simulation results show that the calibrated model has a higher simulated precision for the urban expansion of study area, and the pace of urbanization has become relatively rapid in the study area, which may be closely related to the current land planning, road construction, industrial structure and economic policy.  相似文献

Cities are the drivers of economic growth and structural transformation in developing countries. Transport makes or mars a city. It connects people to opportunity and business to prosperity. Urban transport acts as a catalyst of growth through direct, indirect and induced effects, including those linked to agglomeration and networking externalities. Yet policy makers and planners in developing countries like India continue to neglect the economics of urban public transport. Hardly has there been any attempt to study relationships between city externalities, spatial planning, public transport infrastructure, economic growth and value capture financing. This paper delves into these aspects and presents lessons from theory for the strategies of development and financing of urban public transport in India. It is focused on the implications of urban externalities for transit‐oriented development, transport land use integration, strategic densification of growth nodes and public transport financing based on a value creation, capture and recycling paradigm.  相似文献

Based on the generalized landscape perspective, regional connotation of urban river landscape is expanded. The area connotation of urban river landscape is expanded based on the generalized landscape perspective. In addition to natural and functional attributes, river landscape should be regarded as a regional space element based on heterogeneous space scale. First, as for research method system, the space research models(including ecological footprint, space planning, and landscape pattern index, etc.) coupled with different angle scales and interdisciplinary theory, are utilized to study different correlations and results formed by urban river landscape elements and other regional space elements from the perspective of the regional ecological space, and the overall development goal of the urban river landscape pattern based on the goals of the regional ecological space planning is obtained. Second, the oriented urban river landscape planning and the "M" type close-tonature design strategy are evaluated through the city function zoning orientation and micro-scale urban river landscape pattern index. The research realizes the compatibility of overall goals in terms of the regional ecology, the development of urban functional areas, and the river landscape planning, without losing micro difference and maneuverability based on the urban river landscape planning and design oriented strategy, which innovates the new approach of urban river landscape planning and design with sustainable and balanced development of regional resources, multi-scale, and multiple objectives.  相似文献

Under the impetus of China's urbanization and industry updates, the high-tech new towns (areas) are developing rapidly with an unprecedented scale. The areas which being rich in the natural environment resources, but weak in traffic up are also included in the urban construction lands, and often these urban construction lands is a new city or high-tech development zone of choice. In the city's character building and natural resource protection, the high-tech new town (area) has a lot of issues such as the popular gathering, environmental protection, investment and so on. In this paper, Yantai City of Shandong high-tech Development Zone, an instance of the urban design for the card, summary of the Binhai New Science and Technology Park development characteristics and design requirements, refining the design concept and strategy, shaping the features multi-purpose, rich in content, distinct features of the city park life designed to provide a reference for similar urban planning and design.  相似文献

We investigate the impacts of urban concentration (share of the population living in large cities) on poverty in developing countries. We use instrumental variables to estimate a system linking urban concentration, growth and urban and rural poverty. The results show that the importance of the population living in (small) cities (less than 0.5 million inhabitants) or very large cities (beyond 5 million inhabitants) has no impact on poverty. The importance of cities of 1 to 5 million inhabitants is poverty reducing. We conclude that developing countries with a large share of the population living in very big cities could reduce poverty by deconcentrating their urbanization toward cities of between 1 and 5 million inhabitants.  相似文献

National policydecisions in developing countries contribute to the increasing integration of agriculture into national and world economies. The spatial consequences of national policies, however, vary across regions and agricultural systems. Employing and adapting a methodology first proposed by King (1970), this study explores the relationship between national policy, agriculture, and population characteristics at the regional level in Mexico during the presidency of Carlos Salinas de Gortari (1988–94). Statistical analyses corroborate the hypothesis that the impact of policy reforms on the agricultural sector in Mexico is mediated by the characteristics of the population. Results suggest that government credit for agriculture and federal funding of rural development during the Salinas de Gortari administration were mediated by factors associatedwith the level of urbanization. The provision of commercial credit at the regional level, however, does not appear to depend on population characteristics. Disparities in the impact of national policies are attributed to a historical urban bias, the differential ability of more highly urbanized states to attract government funding, manage and implement programs, and the existence of highly profitable, commercial agriculture in more developed states.  相似文献

Urban historical and cultural heritage has been gradually formed in the long history, it is a witness of the city development history and a realistic carrier of the local civilization. However, protection of urban cultural heritage has been long neglected, with the rapid economic development and urbanization process, a lot of urban cultural heritage that bears important historical and cultural value had gone forever. Ancient cultural remains(ACRs) are an important type of urban cultural heritages, the renaissance of ACRs means the revival of the whole city, how to make ACRs in gradual decline state to be protected with proper planning and renewed vigor has great signifi cance to the urban development. Taking protection and development planning and design of ACRs in Mountain Haoli and its surroundings for example, this study put forward the objectives and principles of ACRs protection and development, extending and deepening the protection methods and renewal strategies, so as to achieve overall cultural, economic and spatial revival of urban ACRs, and sustainable development of ACRs.  相似文献

Access to health care in developing countries, the main destinations of medical tourists, is notoriously uneven, and often becoming more so. Medical tourism, urban bias and privatisation have combined to exacerbate this trend. This is exemplified in both Thailand and India, where regional areas have been disadvantaged by the migration of health-care workers to hospitals focusing on medical tourism, neo-liberal national financial provision for medical tourism (and related tourism campaigns) and evidence of trickle-down gains is lacking. Medical tourism challenges rather than complements local health care providers, distorts national health care systems, and raises critical national economic, ethical and social questions.  相似文献
