Understanding the origins and pace of Africa’s urban transition

In this paper the author argues that urbanisation should be understood as a global historical process driven primarily by population dynamics stimulated by technological and institutional change. In particular, disease control and expanded access to surplus energy supplies are necessary and sufficient conditions for urbanisation to occur given historical evidence of an inherent human propensity to agglomerate. Economic development, which has traditionally been viewed as the primary driving force behind urbanisation, can accelerate the process but is not a necessary condition for it to occur. Informed by this historically-grounded theory of urbanisation, a range of qualitative and quantitative evidence is used to explain the stylised facts of sub-Saharan Africa's urban transition, namely the late onset of urbanisation in Africa vis-a-vis other major world regions, the widely noted but inadequately explained phenomenon of 'urbanisation without growth' observed in Africa in the 1980s and 1990s, and the historically unprecedented rates of urban population growth seen in the region throughout the late twentieth century

China’s Urban Transition

China's role as the world's largest country and global manufacturing behemoth commands attention, along with apprehension over tremors arising from its complex rural-urban adjustments. John Friedmann, a well-known, retired UCLA urban and regional planner, wrote this book for the people he represents: intelligent, interested nonspecialists. He succeeds admirably with an amply illustrated volume of 128 pages, accompanied by copious notes and references revealing his academic background. A few geographers are included in his readings, although they are greatly outnumbered by historians and sociologists. Covering the post-Mao period from 1980 to 2005, Friedmann focuses on the varieties of urban processes and outcomes across China that he sees as compellingly huge and important for the future. The following section summarizes the book's main chapters, concluding with a discussion of some of the most important points he considers

No. 08: Climate Change and Food Security in Southern African Cities

The current urban transition in the Global South is at the heart of discussions about the relationship between climate change and food security. This paper explores the links between climate change and food security within the context of the urban transition taking place in Southern Africa. Climate change is expected to negatively accentuate existing levels of urban food insecurity and these adverse impacts are likely to fall disproportionately on the poor. Researchers, planners and policymakers in Southern African cities are starting to explore how changes in weather associated with climate change are likely to affect urban lifestyles and systems. In order to do this, it is important to understand how climate science knowledge is used at the level of the city and how the impacts of climate change might affect city functioning at the metropolitan and household scales. One of the critical areas that has not been addressed in any detail is the extent to which climate change will affect the food security of the city and its inhabitants, especially within the context of high levels of poverty and widespread food and nutrition insecurity. This paper argues that it is important to understand the linkages between climate change and food security in Southern African cities to begin to design and implement pro-poor planning and programming

Spanish housing markets during the first phase of the rural-urban transition process

This paper discusses how Spain’s housing markets reacted to the far-reaching changes that affected the demand for dwellings during the first phase of the rural-urban transition process. To this end, we construct a new hedonic index of real housing prices and assemble a cross-regional panel dataset of price fundamentals. The results of our econometric analysis suggest that housing markets did not face supply constraints, responded swiftly to the growing demand for accommodation and were efficient. In light of this new evidence, we conclude that housing markets were not a burden for Spanish economic development and that Spain’s institutional and regulatory frameworks were suitable for the housing needs at the time.Hedonic prices, Demand and supply of housing, Regulation in housing markets

Africa’s urban transition: challenges, misconceptions and opportunities

LSE’s Sean Fox argues that some basic misunderstandings about the nature and causes of Africa’s urban transition have resulted in decades of misguided development policies in the region

On Financing of Urban Transition viewed from the Oresund Area:When the Political Agenda of Urban Transition meets the Market

The “urban transition” agenda is as a conglomerate of ambitions derived from international policy documents and as applied in the Oresund area. Encompassing locally set goals for (i) climate change mitigation; (ii) energy efficiency; and (iii) human wellbeing in the built environment. Its implementation is largely dependent on private sector joining in, since transitioning the building stock is to be financed by the market. This paper explores strategies to meet this agenda in the Oresund area. A particular focus is on the refurbishment of multi-family housing relative to these set goals. The paper finds meaningful differences between Denmark and Sweden. In general, exceptionally high energy standards come at an additional cost that is likely to be incompatible with rational economic behavior. Furthermore, actions appropriate for one goal are likely to have modest effects on ancillary goals. The paper concludes by suggesting to revisit current strategies in the Oresund area to reflect market constraints and to promote more coherent ways to achieve the set goals

Housing affordability during the urban transition in Spain

During the decades previous to the Civil War, Spain experienced a rapid process of urbanization, which was accompanied by the demographic transition and sizeable rural-urban migrations. This article investigates how urban housing markets reacted to these far-reaching changes that increased demand for dwellings. To this end, we employ a new hedonic index of real housing prices and construct a cross-regional panel dataset of rents and housing price fundamentals. This new evidence indicates that rents were not a significant financial burden on low-income families and, hence, housing was affordable for working classes. Also, we show that families' access to new homes was facilitated by a sizable growth of housing supply. Substantial investments in urban infrastructure and the institutional framework enabled the construction of new homes at affordable prices. Our results suggest that housing problems were not pervasive during the urban transition as the literature often seems to claim.Financial support was received by the Spanish Ministry of Economy and Competitiveness projects: 2013/00066/001 (Juan Carmona), ECO2011-25713 (Markus Lampe) and ECO2012-39169-C03-01 (Joan R.

The role of urban living labs in a smart city

In a rapidly changing socio-technical environment cities are increasingly seen as main drivers for change. Against this backdrop, this paper studies the emerging Urban Living Lab and Smart City concepts from a project based perspective, by assessing a series of five Smart City initiatives within one local city ecosystem. A conceptual and analytical framework is used to analyse the architecture, nature and outcomes of the Smart City Ghent and the role of Urban Living Labs. The results of our analysis highlight the potential for social value creation and urban transition. However, current Smart City initiatives face the challenge of evolving from demonstrators towards real sustainable value. Furthermore, Smart Cities often have a technological deterministic, project-based approach, which forecloses a sustainable, permanent and growing future for the project outcomes. ‘City-governed’ Urban Living Labs have an interesting potential to overcome some of the identified challenges
