    Die invloed van klimaatverandering op die Suid-Afrikaanse stad en voorgestelde aanpassings
    (Department of Urban and Regional Planning, University of the Free State, 2016) Conradie, Dirk
    English: The purpose of this article is to research the effect of climate change on the South African city and to recommend appropriate measures, based on the specific climatic zone. With increased climate change, it is getting increasingly important that the South African city should be resilient. Recently, the CSIR produced new climate and energy maps to replace the SANS 204 (2011) South African National Building Standards six zone climatic region map. To ensure the long-term applicability of the new climate map, it was decided that, over and above the use of historic climatic data, climate change should also be considered. An A2 climate change scenario of the Special Report on Emission Scenarios (SRES) for the period 1961-2100 (Engelbrecht et al., 2011: 649) was used. An A2 scenario can be described as business as usual. Recent research predicts that southern Africa can expect a temperature increase of between 4°C to 6°C in hot western dessert areas (Engelbrecht & Engelbrecht, 2016: 247-261). Simultaneously, the amount of energy in the atmosphere increases, causing higher intensity storms (Emanuel, 2005: 686-688). The significant warming will have a severe impact on cities where the so-called Urban Heat Island (UHI) causes cities to be significantly warmer than surrounding rural areas. These factors indicate that climate change will have a significant impact on the southern African city.

    Towards more compact South African settlements through informal housing: the case of backyard densification in Bridgton and Bongolethu, Oudtshoorn
    (Department of Urban and Regional Planning, University of the Free State, 2016) Lategan, Louis; Cilliers, Juanee
    English: This article engages the concepts of urban sprawl and density, as the foundations for a discussion on South Africa’s informal backyard rental sector. This research attempts to relate some of the spatial impacts levied by the backyard sector in post-apartheid South Africa, based on case study research in Oudtshoorn, Western Cape, the Rose Valley formalisation project, as well as the Bridgton and Bongolethu townships. This article employs both qualitative and quantitative analyses and arrives at several key findings. Results show that informal backyard rentals increase dwelling unit and population densities substantially in the case study, accommodating households who would otherwise occupy land illegally on the urban periphery, contributing to urban sprawl. Findings also suggest that these backyard tenants enjoy excellent access to services, placing increased pressure on Oudtshoorn’s already overcapacitated infrastructure network. This article posits that informal backyarding has to be encouraged and supported based on the sector’s contribution to urban compaction, but that related impacts on infrastructure be addressed in future planning interventions.
