In broader terms, the paper refers to the topic of brownfield regeneration, as one of the most complex mechanisms for sustainable spatial development. In addition to the fact that brownfield regeneration demands a variety of instruments, such as: tax subsidies, the change of land use ownership, soil remediation, planning regulative amendments, etc., the complexity of brownfield regeneration is primarily seen in a number of stakeholders participating in such a process.

The surface urban heat island (SUHI) effect can be defined as the relative warmth of urban surfaces compared with its surroundings due to the difference in their respective cooling rates. Classic studies have demonstrated that urban warming is a regional and occasional phenomenon whose occurrence depends on weather conditions and characteristics of the urban fabric. Satellite imagery and GIS are combined in this paper to unveil patterns in thermal variations across cities and relate air temperature to density or land cover.

This is an empirical study of economic measurement of the optimal size of
seven cities in West Sumatra region, Indonesia. The empirical findings are quite interesting
since the calculated optimal city size does not result in a single measure as mostly
previous studies found, but they vary in accordance with the economic approaches used.
The optimal city size measured by using the maximum profit approach would have been
larger in size compared to those measured by the minimum cost and maximum net benefit

Resumen

Today, more than half the world’s population lives in cities. By 2030, it is projected that 6 in 10 people will be urban dwellers. By 2050, the figure will have risen to 6.5 billion people; representing two-thirds of all civilization. Taking into account the increasing rural to urban migration and the rapid growth of cities in the developing world, it is clear that cities face a myriad of problems that may hinder planned growth and development.

Den Begriff des Urbanen in Auseinandersetzung mit dem Suburbanen zu bestimmen, ist horizonterweiternd. Nicht, dass er nach der Lektüre von Suburban Constellations an Schärfe gewonnen hätte, wohl aber hat sich meine Aufmerksamkeit für scheinbar banale Phänomene außerhalb der Stadt geschärft. Neu ist die enorme Bandbreite suburbaner Fallstudien aus dem ‚Globalen Norden‘ und dem ‚Globalen Süden‘, die hier versammelt werden.

Many internally displaced people (IDPs) find refuge in cities. However, the scale of global urban internal displacement caused by violence, conflict, disasters and development projects is unknown. Cities struggle to accommodate IDPs since their movements are largely spontaneous, and some authorities may resist helping IDPs for fear of encouraging further influxes. Meanwhile, IDPs face displacement-specific challenges to rebuild their lives in urban settings and may be displaced again in the process due to lack of housing tenure security and violence and insecurity.

The New Urban Agenda represents a shared vision for a better and more sustainable future – one in which all people have equal rights and access to the benefits and opportunities that cities can offer, and in which the international community reconsiders the urban systems and physical form of our urban spaces to achieve this.

This article explores the ways in which (a) Indigenous youth involved in an HIV intervention took up and reclaimed their cultures as a project of defining ‘self’, and (b) how Indigenous ‘culture’ can be used as a tool for resistance, HIV prevention and health promotion. Data were drawn from the Taking Action Project: Using arts-based approaches to develop Aboriginal youth leadership in HIV prevention.

This compendium and analysis of Cities in the BRICS countries were developed through a partnership between the South African Cities Network (SACN) and the South African Research Chair in Spatial Analysis and City Planning (SA&CP) at the University of the Witwatersrand. Since South Africa joined BRICS in 2010, multiple connections have been forged between South Africa and its alliance partners. However, although there is a growing volume of engagements, there is still inadequate knowledge and understanding across the BRICS.

Cities are about people, first and foremost. In addition, as the national integrated urban development framework states, South African cities should be safe, liveable socially integrated, economically inclusive and globally competitive, with an active citizenry. The 2016 State of Cities Report (SoCR) makes an important call to action for all segments of society, from communities and neighbourhoods to cities, from cities to the nation and from the nation to the global, to support the inclusive growth and development of South African cities.
