Urban growth management-the Saudi experience

Saudi Arabia experienced a high rate of urbanization during the period 1970–1986 resulting in accelerated annual growth rates for Saudi cities averaging more than 6.4%. Higher than usual growth rates created demand for the opening up of huge areas to meet housing, commercial, industrial and other land uses. Government's land grant policy and liberal interest free loans resulted in massive expansion of cities and towns all over the country with major cities of Riyadh, Jeddah, and Dammam having the biggest share. Lack of planning frameworks and weak city institutions could not direct the growth properly leading to sprawl and lop-sided development. This meant rapid extension of road network and utilities with high financial outlays. The slow-down in the economy and ever-increasing demand for infrastructure provision forced the government to initiate growth boundaries to tackle these problems in 1986. The paper discusses the methodology adopted and the process of devising urban limits and evaluates their impact on urban structures of Saudi cities. The paper draws some conclusions in the realization of objectives of the exercise with respect to, (a) control urban sprawl by encouraging infill development where utilities were generally available; (b) reduce cost of provision of infrastructure through better coordination tied to commonly agreed phasing; (c) maintain natural environment around the cities.     

Challenges to the enforcement of development controls in the Wa municipality

The imposition and enforcement of a land-use regulation is extremely important if society is to reap the full benefits of its stock of land. Ghana has therefore enacted various statutes to regulate land development throughout the country. This paper examines development controls in the Wa Municipality. It finds out the challenges confronting the development control process in the municipality. The paper does these through a review of the development control literature. It also reviews the legal framework for development controls in Ghana. It used questionnaires to gather data from the officials of the Municipal Building Inspectorate Division (MBID), Wa. It used questionnaires to solicit the opinion, knowledge, experience and perception of land developers on the development control regime in the municipality. It revealed that development controls are not adequately enforced in the Wa Municipality. It notes that uncontrolled developments are a common sight in the municipality. It also established that socio-cultural reasons, political interferences, limited public knowledge on the essence of development controls, and an under-resourced building inspectorate division are responsible for this state of affairs. It recommends that the Wa Municipal Assembly strictly enforce its land-use regulations to ensure that the residents of the municipality fully benefit from the imposition of land-use regulations.     

Urban heritage endangerment at the interface of future cities and past heritage: A spatial vulnerability assessment

Uncontrolled urban growth has been an increasing concern in many regions throughout the world. Generated by a natural tendency of population growth in relation to unsustainable land use, city sprawl has led to complex spatial developments that are creating both benefits to, and challenges for decision makers. A major problem inherent in the uncontrolled growth of cities is the threat to the fragile cultural and ecological heritage, which may escalate to permanent and irreversible damage as a result of factors such as environmental depletion and landscape decay. Using modern geosciences and spatial information technologies as predictive tools to analyse and forecast urban growth, a regional spatial decision system may be useful in order to provide seemly and timely information on the risk of overburdening the carrying capacity regarding the historico-cultural heritage at local and regional levels.The present paper develops a predictive toolkit for urban heritage in relation to urban cultural endangerment. This common problem is shared through many regions of the world and is increasingly jeopardizing fragile archaeological landscape due to urban pressure. In this sense, and to forecast an example of this common pressure, the Algarve is exemplified as a laboratory for testing this novel methodology, relying on a combined analysis of urban growth potential and threats to the abundant presence of archaeological heritage in the area. Our appro ach supports the paradigm of city growth in the context of a common agenda emerging from the Valetta Treaty, in which preserving the archaeological heritage is recognized as a key element for sustainable development. The study provides novel empirical results from the above mentioned modelling approach, with important lessons for the developing world. This paper proposes as such, an integrative spatial analysis methodology on the issue of historico-cultural endangerment, which is a new approach to comparative spatial analysis for decision making on urban heritage endangerment at the regional scale. Later, the discussion extends to a more conceptual level of urban planning by considering the questions: Is urban sprawl influencing the way we perceive cities? If so, are there positive advantages in the paradigm of urban growth and urban sprawl which might help us to protect past heritage while ensuring sustainable and modern cities?     

1964 Tokyo Olympics as Post‐War

This is an analysis of the historical continuity of the military‐cultural spatial formation of the Tokyo Olympic Games throughout the prewar and postwar era. The sites that eventually became the basis for hosting the 1964 and 2020 Olympics had already materialized in the plan for the 1940 Olympics. Tokyo's modernization process entailed a shift of the city's core from the rich cultural heritage accumulated since the Edo in the city's northeast towards an area extending from the southwest of the city center into the suburbs. The northeast area of central Tokyo had been home to commoner districts since the Edo period, and with land that was highly subdivided, did not lend itself to large‐scale development. But the southwest of the city center was originally the site of feudal estates, and these large sites were generally amenable to large‐scale development. These areas were home to numerous Imperial Japanese Army bases before the surrender, which after seizure during the US occupation eventually became the footprint for large parks and urban developments. The 1964 Olympics played a determinative role in the developments of the southwest of the city center. This continuity from prewar to postwar planning is reflected in the similar placement of venues, and the their conversion from former military uses. So the Olympics came to postwar Japan as a postwar event, in the strict sense of the word. The term postwar here refers foremost to the strategy of converting the social consciousness from war that accompanied reconstruction and economic growth.     

Managing urban growth and development in the Riyadh metropolitan area, Saudi Arabia

The paper examines public sector management of urban growth and development in the Riyadh Metropolitan Area, Saudi Arabia. The focus of the paper is on institutional capacity building and development intervention. The paper traces changes in public sector management structures and development activities over the history of the city with the aim of assessing development impact and identifying forces that have shaped the evolving state of urban management. The paper notes that urban management has significantly improved with time but the persistence of urban problems coupled with projections of future growth point to the need for further improvements. The paper, in conclusion, while acknowledging the utility of the metropolitan development strategy (MEDSTAR) being formulated for the city, points to the need for broader administrative reform to improve the ability to cope with long-term challenges of growth in the city. Some issues that reform could address are suggested.     

Towards a theory of the American rural residential land market

Since the late 1960s there has been a notable acceleration in America in the demand for rural residential land within commuting range of urban and suburban employment and service opportunities. American rural residential households do not seem to purchase acreage tracts primarily for their ‘productive’, or resource value, however. Instead, they purchase rural land for its ‘consumptive’ or residential value, as its value is primarily derived from the bundle of residential attributes associated with it. Over time, rural land within commuting range of metropolitan areas becomes underproductive and idled — a situation which precedes urban sprawl. Rural residential development has thus become a focus of debate on the effects and inefficiencies associated with urban sprawl. Yet, not enough is known about the nature of the rural residential land market. It is argued that American rural residential households are different from their suburban and urban counterparts for at least three reasons. First, they are distinguishable for their pursuit of self-sufficiency, self-expression, and the cultural status that a rural residential lifestyle offers. Second, they seek low cost rural jurisdictions in order to afford more housing and land than they could afford in higher cost urban and suburban locations. Third, they value distance from the city center colinearly with externalities such as pollution, crime, overcrowding, and noise associated with central city areas. In the latter sense, American rural residential households value land more highly the farther away it is from the city center, but discount land value the farther away it is from the boundary of urban development. In light of these considerations, this paper (a) reviews the literature describing the motivations of American rural residential households, (b) poses a theory of the American rural residential land market, (c) applies the theory to a case study, and (d) offers implications of the theory to planning efforts aimed at preserving resource land and containing urban sprawl.     

Restructuring for growth in urban China: Transitional institutions,urban development,and spatial transformation

This research examines government policies and urban transformation in China through a study of Hangzhou City, which is undergoing dramatic growth and restructuring. As the southern center of the Yangtze River Delta, an emerging global city region of China, Hangzhou has been restlessly searching for strategies to promote economic growth and survive the competition with Shanghai. This paper analyzes Hangzhou’s development strategies, including globalization, tourism, industrial development, and urban development, in the context of shifting macro conditions and local responses. We hold that urban policies in China are situated in the broad economic restructuring and the gradual, experiential national reform and are therefore transitional. The paper suggests that China’s urban policies are state institution-directed, growth-oriented, and land-based, imposing unprecedented challenges to sustainability and livability. Land development and spatial restructuring are central to urban policies in China. Last, while Hangzhou’s development strategies and policies to some extent reflect policy convergence across cities in China, local/spatial contexts, including local settings, territorial rescaling and land conditions, are underlying the functioning of development/entrepreneurial states.     

Assessing the transportation consequences of land use transformation in urban China

This paper assesses the accessibility and mobility consequences of urban land transformation in expanding Chinese cities. It defines transportation–land use connections in China's context and analyzes the accessibility and mobility uncertainties associated with current urban development themes, including the formulation of CBD, the development of satellite communities, and the evolution toward multi-center layout. This article points out that appropriate accessibility and mobility objectives are not well considered in land development, and current development themes tend to lengthen trips and lead to increased congestion in the context of growth and motorization. A strong national leadership is needed to help city governments integrate accessibility and mobility objectives into urban development.     

Urban growth patterns and growth management boundaries in the Central Puget Sound, Washington, 1986–2007

Many regions of the globe are experiencing rapid urban growth, the location and intensity of which can have negative effects on ecological and social systems. In some locales, planners and policy makers have used urban growth boundaries to direct the location and intensity of development; however the empirical evidence for the efficacy of such policies is mixed. Monitoring the location of urban growth is an essential first step in understanding how the system has changed over time. In addition, if regulations purporting to direct urban growth to specific locales are present, it is important to evaluate if the desired pattern (or change in pattern) has been observed. In this paper, we document land cover and change across six dates (1986, 1991, 1995, 1999, 2002, and 2007) for six counties in the Central Puget Sound, Washington State, USA. We explore patterns of change by three different spatial partitions (the region, each county, 2000 U.S. Census Tracks), and with respect to urban growth boundaries implemented in the late 1990’s as part of the state’s Growth Management Act. Urban land cover increased from 8 to 19% of the study area between 1986 and 2007, while lowland deciduous and mixed forests decreased from 21 to 13% and grass and agriculture decreased from 11 to 8%. Land in urban classes outside of the urban growth boundaries increased more rapidly (by area and percentage of new urban land cover) than land within the urban growth boundaries, suggesting that the intended effect of the Growth Management Act to direct growth to within the urban growth boundaries may not have been accomplished by 2007. Urban sprawl, as estimated by the area of land per capita, increased overall within the region, with the more rural counties within commuting distance to cities having the highest rate of increase observed. Land cover data is increasingly available and can be used to rapidly evaluate urban development patterns over large areas. Such data are important inputs for policy makers, urban planners, and modelers alike to manage and plan for future population, land use, and land cover changes.     

Using best available science to protect critical areas in Washington state: challenges and barriers to planners

Urban development has profound impacts on ecological patterns and processes making the scientific information required for developing environmental ordinances central for mitigating these negative ecological impacts. Washington State requires that planners use the best available science (BAS) to formulate land use ordinances as part of the state’s Growth Management Act (GMA). We present empirical findings describing challenges to planners in defining “best available science” and using BAS to create local ordinances that balance development needs with natural resource protection. We interviewed city and county planners (and their consultants) in western Washington to determine what they find useful about BAS, whether or not BAS is applicable to their jurisdictions, and what constraints they experience in reviewing and using BAS to create or update their land use ordinances. Our results suggest that applying the BAS requirement is particularly difficult in urban areas. Specifically, planners had difficulty applying results from research conducted in systems dissimilar to their urban landscapes. These challenges to planners were exacerbated by (1) a lack of resources and (2) political tensions among stakeholders with competing values in urban settings. We conclude with recommendations for improving the consideration of science in statewide land-use planning.     

The Loss of Friends to Homicide and the Implications for the Identity Development of Urban African American Teen Girls

Homicide is the leading cause of death of African American youths in the United States. The loss of their friends to these deaths challenges the identity development of many urban African American teen girls. To understand the implications of such a loss on the psychosocial task of identity development of urban African American teen girls, 21 African American girls, 16–19 years old, living in a large Northeastern city in the United States, participated in a qualitative study. Semi-structured, in-depth interviews were conducted. A grounded theory, constant comparative approach, is used to analyze the narrative data. The findings show (a) the presence and pressure of psychosocial stress on the participants’ identity development process, (b) the adaptive functions of foreclosed religious identity commitments, (c) the potential for this event to inform, in complex ways, racial identity development examined through racial group orientation, and (d) natural avenues of resistance to marginalization and race devaluation that may be experienced from societal responses to this event. How the teens make meaning of this experience informs their identity development. The article promotes the inclusion of identity-informed psychosocial interventions in bereavement work with this population.     

Incorporation and Gated Communities in the Greater Metro-Los Angeles Region as a Model of Privatization of Residential Communities

ABSTRACT

The privatization of urban public space has accelerated through the closing, redesign, and policing of public parks and plazas, the development of Business Improvement Districts (BIDs) that monitor and control local streets and parks, and the transfer of public air rights for the building of corporate plazas ostensibly open to the public. In the suburbs, privatization also takes the form of conservation easements that restrict access to public lands, the creation of shopping malls and new town centers relocated within these private commercial developments, and the building of gated residential communities. Accompanying this expansion of private interests are changes in strategies of governance and regional differences in how local governments and residents are encouraging private encroachment on public space. This article focuses this third set of privatization practices by discussing how gated communities manipulate municipal and town planning laws to control public space and tax dollars. To accomplish this task, I discuss the emergence of gated communities as a new form of privatization of urban/suburban space and then tease out the legal and institutional underpinnings of this spatial governance. The geography of gated communities in greater metro-Los Angeles region and their use of the strategy of incorporation to capture public taxes for private use is employed as a model for understanding the future of gating in the United States. The Los Angeles model is then compared to current gating patterns in urban and suburban gated communities in New York and Texas. These manipulations of private land use controls in the United States are not necessarily new, but with gating there is an accelerating trend away from governmental and public control of land use toward an increased reliance on privately created controls. The consequences of this shift toward privatization of land use control is an impoverishment of the public realm and access to public resources, especially public space.     

Spatial disintegration and arable land security in Egypt: A study of small- and moderate-sized urban areas

While commonly associated with regional ‘mega-cities’, rapid urbanization in the less-developed world has also begun to define growth in small- and moderate-sized settlements on the periphery of major metropolitan areas. The dispersal of population growth to these smaller areas holds significant implications for environmental, economic, and social health, and threatens local food security, increases congestions, and induces difficulty in service provision. This study examines the effects of spatial disintegration and rapid urbanization in the stock of arable land in Egypt. To assess this issue, the study will meet three objectives. First, we evaluate the relationship between population growth and urban land cover expansion in small- and moderate-sized settlements in Egypt. Second, we consider the role of selected geographic determinants in influencing the growth of these areas through the use of a regression model. The selection of an appropriate model type is a sub-objective and will be discussed further. Third, these drivers of growth will be assessed through their effects on the country’s stock of arable land. These objectives will be met through the development and application of the regression models, in order to examine the relationship between urban land expansion and several independent variables. An increase in population is found to have a positive and statistically significant effect on corresponding urban land cover area. Surprisingly, the variables commonly associated with urbanization in Egypt - proximity to major roads, the capital of Cairo, and the Nile River - though exhibiting a positive relationship with urban growth, are not statistically significant in the selected case studies. This research underlines the necessity for a combined approach to policy formation - with input from policy fields as varied as agriculture, urban planning, and land reclamation - to slow outward growth and maintain arable land stocks.     

Conflicts in urban fringe in the transformation era: An examination of performance of the metropolitan growth management in Beijing

The performances of urban growth management are often criticized because their original objectives are frequently inconsistent with local development facts. Underlying the many reasons for this are the political and institutional contexts that influence policy-making and development activities. The urban fringe, a zone is managed to against urban sprawl in many countries, represents the conflicts between urban management system and local development resulting from political transformation. This study examines the case of decentralised-concentration strategy, one of the most important metropolitan growth management in Beijing since the 1990s, and sheds some lights on the performance of the growth management in the transformation context. The results suggest that the aims of municipal growth management to concentrate developments in urban fringe have partly been achieved through actual local developments; however, some unexpected and illegal local developments outside the planned areas are counterproductive from the perspective of municipal growth management. The performance of the present growth management is being challenged by new trends towards political decentralisation and locally fiscal responsibilities. In the interest of future policymaking, the dominant central planning system in Beijing should take these decentralisation trends into growth management account, compared with the great progress in decentralisation in economy system. The urban policy needs to shift from the dictatorial manner and put more efforts into creating a harmonious relationship between municipal growth management and actual local demands on development.     

How small cities affect the biodiversity of ground-dwelling mammals and the relevance of this knowledge in planning urban land expansion in terms of urban wildlife

Fundamental principles regarding urban biodiversity are based on studies conducted in large cities. However we cannot know whether the same phenomena occur in smaller cities or how small cities affect biodiversity. Small cities are an inherent element of urbanization and in the future, most global urban growth is expected to take place in small and medium-sized cities. Understanding the effects of small cities on biodiversity will be an important aspect in planning urban land expansion. Our study examined the effects of a small city on communities of small ground-dwelling mammals on 41 sites arranged in a four step gradient of urbanization. In 6700 trap-days, we caught 2333 individuals comprising 15 species. In the downtown area the same phenomena as those described for large cities were observed: a reduction in species richness and diversity, a decline in the abundance of urban sensitive species and an increase in synurbic species. However, in contrast to large city studies, green areas outside the downtown area did not differ from rural sites in small mammal population parameters. This phenomenon of relatively unchanged fauna outside the downtown area shows that small cities have the potential to maintain a high level of diversity of small ground-dwelling mammals if appropriate planning of further building expansion is implemented. More studies of small cities are needed to better assess their impact on biodiversity. This knowledge can then be applied in better planning for urban wildlife. Generalizations based solely on large city studies are inadequate and may lead to incomplete or inappropriate conservation strategies for small cities.

Urban policy,economic policy,and the growth of large cities in China

It is argued that despite a Chinese national urban policy large cities are still growing rapidly. Policy implementation is considered weak. It is suggested that a better strategy for increased urbanization in large Chinese cities would include integrating urban with economic policy, improving urban facilities, and planning and managing large cities. A short review is given of theories on city size and development in developing countries. Chinese economic reforms and their impact on urban growth are described. During 1978-90 the level of urbanization rose from 17.9% to 26.4%. Five periods during 1949 to present are identified as exhibiting distinct development profiles. Over the 40 year period, policies pertaining to cities of a particular population size changed constantly. During the early 1950s, development focused on major coastal cities and newly expanding industrial centers. After the 1950s and the Great Leap Forward (1958-60), rural areas and small urban places were the focus of Maoist development. Large cities were de-emphasized. The early 1970s emphasized the development of rural industries and small urban places in order to reduce rural-urban inequalities. A national urban policy was prepared in the early 1980s. The aim was to control the size of large cities, to develop medium sized cities, and to develop small cities. This policy was amended later and is now China's Urban Planning Law. However, the percentage of the nonagricultural population (NAP) living in cities of a million or more persons increased from 37.5% in 1978 to 41.6% in 1990. The share of NAP living in small cities increased to 21.5% in 1990. Temporary migrants were an estimated 5-15% of large city populations. Most cities were beyond their population control limit. Large cities had served important roles in development: greater efficiency in the industrial labor force and more profits; centers for culture, education, politics, and transportation; and links to foreign countries. Economic reforms fueled growth. At present controlled growth is an obstacle to economic development in large cities. Improvement is needed in urban management.     

Measures towards a comprehensive municipal GIS—the case of Ar-Riyadh Municipality

The capital city of Riyadh is experiencing growth at a rate exceeding 3% annually. The Riyadh Municipality must support this substantial growth with effective and efficient infrastructure-related facilities and public services by integrating people, business strategies, and technology. The Municipality has used a number of innovative approaches to provide this support. Of these, certain uses of Geographical Information Systems (GIS) may be one of the most interesting.This paper investigates the use of GIS, as well as Internet/Intranet and Imaging, by the municipal government, focusing particularly on its applications in the granting and administration of building permits. In order to operationalize the GIS system in this instance, the specific needs and requirements of the Building Permits Section were taken into account in designing the system. The paper outlines the functional specifications of the new municipal approach.     

发展陷阱：城镇化建设何去何从？

中国历经30多年的高速经济增长,重返社会建设既是现实的需要,也是发展规律的内在要求。随着城乡社会的融合,村庄在消逝,城市人与农村人的权利心理在走向趋同。乡土社会经济正在消逝,取而代之的是城市社会的快速扩张,非农、非正规经济在农村土地上快速长成,而这一过程其实又是一次试错运动。推进中国的城市化,不是解除户籍和土地制度的束缚,而是依靠生产方式转变和农民收入提高,以及农村的土地经营模式的改变。城镇化道路的选择,关注重点应该是农村而不是城市,出路在于城市建设稳步推进以及其与农村社会经济发展之间的协调。     

Assembling the pieces: a framework for the integration of multi-functional ecological main structure in the emerging urban region of Bogotá, Colombia

Bogotá, the capital of the Republic of Colombia, is a tropical highland city located 2,650 m above sea level. It is the 25th largest city in the world and, among large cities, is also one of the highest. In common with other cities in Latin America, a large part of its urban growth during recent centuries has been unplanned and informal. The introduction of green spaces into urban planning in Bogotá began in the mid-20th century, but was first included in official legislation during the 1990s through the concept of Ecological Main Structure (EMS). Initially developed by Dutch scholars, EMS was brought to Colombia via biological conservation practitioners as a means of enhancing biological connectivity in rural and natural landscapes, extended in this case to urban landscapes as a top-level planning instrument. EMS originally included a variety of components, from protected areas and biological conservation tools to environmental urban elements - the emphasis being on biodiversity conservation, without sufficient recognition of specific urban structures and functions. This process led to conceptual disciplinary-based divergence and conflicting political interpretations. The current emergence of EMS as a planning tool for urban regions represents an opportunity for integration, although the risk of divergent interpretations remains, as no integrative conceptual framework has yet been developed. In this paper we review the concepts underlying EMS that have been incorporated within urban and regional planning, especially those of ecological networks and green infrastructure, and also diagnose conceptual and institutional barriers to its current integration, challenges and opportunities which are set in the context of an emerging urban region. We propose a trans-disciplinary framework for multi-level integration of EMS, along a gradient from wild environments to built structures that incorporates emerging concepts such as urban biodiversity, ecosystem services and design in the urban landscape, with the aim of contributing to the creation of an urban landscape that is resilient to environmental change and suitable for human well-being and adaptation.
