    Mapping vulnerability to COVID-19 in Gauteng
    (Gauteng City-Region Observatory: Map of the Month, March 2020, 2020-03-20) de Kadt, Julia; Gotz, Graeme; Hamann, Christian; Maree, Gillian; Parker, Alexandra
    The world is reeling as COVID-19 infections spread. This Map of the Month aids an understanding of the localised risk factors that might contribute to transmission of COVID-19, or amplify its health and socio-economic impacts in Gauteng communities. It explores two key themes: (1) the multiple risk factors to maintaining social distance and preventative hygiene; and (2) the multiple risk factors for health and socio-economic vulnerability during an outbreak or broader shutdown.

    Towards applying a green infrastructure approach in the Gauteng City-Region
    (Gauteng City-Region Observatory, 2019-12) Culwick, Christina; Khanyile, Samkelisiwe; Bobbins, Kerry; Dunsmore, Stuart; Fitchett, Anne; Monama, Lerato; Naidu, Raishan; Sykes, Gillian; van den Bussche, Jennifer; Vieira, Marco
    The Gauteng City-Region (GCR) regularly experiences heatwaves, raising renewed concerns over water security, as well as heavy and persistent rains, leading to severe flooding in some areas. In this context of heightened climate variability, thinking about ways to redesign our urban areas with more sustainable infrastructure solutions is becoming more and more important. Green infrastructure (GI) is emerging as an alternative approach to traditional (‘grey’) infrastructure in urban planning and development. Its emergence can be understood in terms of the growing demand for infrastructure and services, increased concerns over natural resource constraints and climate change, and the negative impacts associated with traditional approaches to designing and building cities. It has been proposed that GI can provide the same services as traditional infrastructure at a similar capital cost, while also providing a range of additional benefits. However, despite greater policy interest in green infrastructure in recent years, traditional infrastructure solutions to urban problems continue to dominate. This is partly due to the lack of a systematic evidence base to support GI implementation. There have been calls from decision-makers for more concrete examples of the benefits of successful urban GI applications, as well as for practical guidelines on their implementation. Towards applying a green infrastructure approach in the Gauteng City-Region is the GCRO’s eleventh Research Report. This report builds on the findings of two previous green infrastructure reports, as well as a CityLab process run with academics and government officials between 2014 and 2016. These outputs and the CityLab discussions highlighted as critical the need to for a deeper evidence base in building support for, and enhancing investment in, the GI approach. Unlike the earlier studies which were more theoretically grounded and policy oriented, this report comprises a number of technical investigations that more practically reflect on how a GI approach could be incorporated into urban planning in the GCR, and in other similar urban contexts.
