The Cost

Recently, research on sprawl was increasing due to its impacts on the economy, society, and environment. Several studies have focused on the application of containment strategies to curb urban sprawl. Urban growth boundaries (UGBs) were among the containment policies adopted to tackle the issue of sprawling cities. This paper set out to undertake an analysis of the factors influencing the performance of the UGB of Riyadh City. A qualitative data analysis using NVivo12 software was adopted. To collect the required data of UGB, semi-structured interviews were conducted with nine experts involved in urban management, Riyadh city development, and other planning agencies. If the application of UGB policy in the western countries has managed to restrain more or less city sprawl, its replication to the case of Riyadh seems to have had some adverse impacts. That is, instead of controlling urban sprawl, it has stimulated it. The reasons may lie in the deficiency of monitoring and evaluation of urban studies, free provision of infrastructure, and lack of coordination between different city planning agencies. Understanding the factors affecting the UGB efficiency​will assist policymakers and urban planners in reducing the spread of scattered and leapfrog residential development, lowering the cost of service supply and promoting infill development

Urban Growth Boundaries

The urban growth boundary (UGB) plays an important role in the regulation of urban sprawl and the conservation of natural ecosystems. The delineation of UGBs is a common strategy in urban planning, especially in metropolitan areas undergoing fast expansion. However, reliable tools for the delineation of informed UGBs are still not widely available for planners. In this study, a patch-based cellular automaton (CA) model was applied to build UGBs, in which urban expansions were represented as organic and spontaneous patch growing processes. The proposed CA model enables the modeler to build various spatial and socio-economic scenarios for UGB delineation. Parameters that control the patch size and shape, along with the spatial compactness of an urban growth pattern, were optimized using a genetic algorithm. A random forest model was employed to estimate the probability of urban development. Six scenarios in terms of the demand and the spatial pattern of urban land allocation were constructed to generate UGB alternatives based on the simulated urban land maps from the CA model. Application of the proposed model in Ezhou, China from 2004 to 2030 reveals that the model proposed in this study can help urban planners make informed decisions on the delineation of UGBs under different scenarios.

The City

Urban sprawl is a global phenomenon in the contemporary era. It is mostly taking place in the less developed countries due to natural increase and consistent movement of people into the mega cities and large urban centers. The phenomenon has globally gained attention from diverse researchers in the field of urban geography, environmental studies, city and region planning in view of its significant influence on the urban environment. However, the effect of sprawl on urban livability and economy in Nigerian cities is scarcely investigated especially in Northern Nigeria. This research explores the social and economic effects of urban sprawl in Kaduna metropolis. Remote Sensing and Geographic Information System (GIS) Technologies were applied for the analysis. The study found that Kaduna metropolis has experienced a progressive increase in the built-up area; in 2006 it had an aerial coverage of 13,980 hectares, a rise of 107.91% from 2001 aerial coverage of 6724 hectares. In 2012, the city had an aerial coverage of 15,808 hectares, an increase of 13.08% from 2006. Conversely, there has been a remarkable decrease in percentage of vegetation (1,458 hectares) and agricultural (11,739 hectares) land areas. In turn, such changes has adversely affected urban facilities or utilities such as pipe-borne water, electricity, health facilities, schools, security, transportation, wastewater infrastructures and fire safety services, which has become overstressed. Economic crisis has manifested in the rise of unemployment and escalating number of urban poor. Residential land use has encroached into open spaces while commercial activities overrun residential areas. Increase in distance and journey time make travel cost unbearable to the common man. These and social fragmentation retard livability in the city. Thus calls for a balance sustainable development in Kaduna metropolis and effective management of urban growth by the Kaduna Capital Development Board Authority. In due course, smart growth policy, growth management, urban containment, effective land use planning and public facility adequacy have been recommended to foster viable urban growth in Kaduna city and elsewhere.

Contesting the greening of the urban growth machine: Ecological modernization and the promethean counter-discourse

Urban environmental governance and planning are increasingly characterized by the adoption of “sustainability fixes,” namely political compromises which try to conciliate economic and ecological goals in order to safeguard long-term growth. If sustainability fixes have been harshly criticized for being sociospatially selective, resistance to them does not always come from radical groups who demand stronger and fairer measures, but from actors who oppose the idea of sustainability because it goes against their interests, habits, or values. This paper focuses on this “contestation of the greening of the urban growth machine,” by presenting an empirical study of a sustainable mobility policy in Quebec City, Canada, which has given rise to a controversy opposing two divergent perspectives. The first is an ecological modernization discourse advocating for a green and attractive public transit system. The second is a promethean counter-discourse which supports the unconditional growth of automobility and urban sprawl. Results show that even if urban environmental policies are increasingly attuned to the “growth first” logic, they could still face strong opposition, especially from suburban and conservative interests. More generally, this paper shows that, in some contexts, sustainability fixes could be a “better than nothing” solution, namely a step toward fairer and greener cities.

This article explores ways in which land use policy outcomes vary across contexts focusing, as an example, on urban growth boundaries. Specifically, it analyzes how various contextual factors interact with the policy and generate diverging development outcomes by employing a kernel-based regularized least squares method. Results show that the policy effectiveness is largely dependent on the region’s population size, initial density levels, and organizational conditions. The presence of urban growth boundaries also appears to shape the way other determinants influence development patterns, suggesting that the policy can both directly and indirectly promote a more compact/contiguous pattern of development.

For megacities experiencing rapid urbanization in China, urban growth boundaries (UGBs) have been considered as a useful means to control urban sprawl and to promote sustainable urban development. However, scientific methods and tools to delineate sound UGBs by planners are few and far between. Using metropolitan Chengdu as the study area, this paper applies the system dynamics (SD) and conversion of land use and its effects at small region extent (CLUE-s) models to delineate UGBs. In this study, land use demand was simulated in the SD model temporally at a macro-level and allocated in the CLUE-s model spatially at a micro-level. Key social-economic elements and spatial pattern factors were used in the simulation process for the period of 2013–2030. The simulation results under various scenarios showed that areas along the major corridors and belt roads of the main Chengdu metropolitan area and its satellite towns have higher chances to be developed. The areas most likely to be developed were used to establish the UGBs for 2020, 2025, and 2030. This research demonstrates that the integrated framework of SD and CLUE-s models provides a feasible means of UGB delineation under different development scenarios.
