A composite index of quality of life for the Gauteng city-region: a principal component analysis approach

The improvement of the quality of life of all South Africans is high on the agenda at national (The National Planning Commission, 2012) and regional levels of government (The Gauteng Planning Commission, 2012) and it is therefore important to develop an instrument that can measure this multi-dimensional concept. The need therefore exists for a composite index of quality of life with the ability to both track the quality of life of people over time and compare it across different demographic and socio-economic groups. Such a measure could identify those demographic and socio-economic groups with low levels of quality of life and also highlight dimensions that need to be prioritised in order to improve the wellbeing of people.

In South Africa there are a limited number of quality of life indices and measures of wellbeing. Indices that measure wellbeing nationally include: the Quality of Life Index of Moller and Schlemmer (1983), the Living Standard Measure (LSM) Index produced by the South African Audience Research Foundation (SAARF) (2013), the South African Development Index of the South African Institute of Race Relations (2011), and the Everyday Quality of Life Index (Higgs, 2007). The following indices measure wellbeing at a regional level: the Quality of Metropolitan City Life in South Africa Index (Naude, et al., 2009), the Non-Economic Quality of Life Index at Sub-National Levels (Rossouw & Naude, 2008) and the Quality of Life Index of the Gauteng City-Region Observatory (GCRO, 2011).

Although these quality of life indices make distinctive contributions to the study field, the focus of these studies is often to measure only objective or subjective quality of life or only economic or non-economic quality of life, rather than all of the above. Furthermore, many of the indices use equal weighting, which does not necessarily reflect the priorities of the communities.

Modelling urban spatial change: a review of international and South African modelling initiatives

Urban growth and land use change models have the potential to become important tools for urban spatial planning and management. Before embarking on any modelling, however, GCRO felt it was important to take note of, and critically assess lessons to be learnt from international experience and scholarship on spatial modelling, as well as a number of South African experiments that model future urban development. In 2012, GCRO initiated preliminary research into current international and South African modelling trends through a desktop study and telephone, email and personal interviews. This Occasional paper sets out to investigate what urban spatial change modelling research is currently being undertaken internationally and within South Africa. At the international level, urban modelling research since 2000 is reviewed according to five main categories: land use transportation (LUT), cellular automata, urban system dynamics, agent-based models (ABMs) and spatial economics/econometric models (SE/EMs). Within South Africa, urban modelling initiatives are categorised differently and include a broader range of urban modelling techniques. Typologies used include: provincial government modelling initiatives in Gauteng; municipal government modelling initiatives; other government-funded modelling research; and academic modelling research. The various modelling initiatives described are by no means a comprehensive review of all urban spatial change modelling projects in South Africa, but provide a broad indication of the types of urban spatial change modelling underway. Importantly, the models may form the basis for more accurate and sophisticated urban modelling projects in the future. The paper concludes by identifying key urban modelling opportunities and challenges for short- to long-term planning in the GCR and South Africa.

The map of Gauteng: evolution of a city-region in concept and plan

The mission of the Gauteng City-Region Observatory (GCRO) is to help illuminate trends and dynamics shaping the region of towns and cities in and around Gauteng, and also enhance understanding of the idea of the Gauteng City-Region (GCR) as a project – a different way of thinking about and governing this space. While much of the data collection and analysis work of the GCRO is focused on the present, we also consider the city-region’s past and its possible futures.

A 2030 National Development Plan, crafted by the National Planning Commission, has recently been adopted. In addition the Gauteng Provincial Government, working with municipal partners and business, civil society and labour stakeholders, is drafting a G2055 long-term development plan. As our society looks forward to what sort of country and region we need to become, it is also important to look backward. Understanding the past gives us insights into how we have come to be where we are now, and so in turn what paths we should tread into the future.

This Occasional Paper is one of two that GCRO has commissioned specifically to deepen our understanding of the past of the GCR. Both focus on aspects of the region’s spatial past, and ought to be read together. This paper by Alan Mabin explores how the idea of a city-region found expression in various statutory planning frameworks over the course of the last century, and how embryonic cityregion concepts influenced spatial decisions and developments. The companion paper by Brian Mubiwa and Harold Annegarn considers the different but related issue of the actual historical spatial evolution of the GCR. It examines key spatial changes that have shaped the region over a century and provides a remarkable picture, based on satellite imagery, of regional spatial growth in the last two decades.
