Green assets and infrastructure

'Green assets and infrastructure’ is a multi-year project examining the current state of green infrastructure (GI) in the GCR and, in particular, how GI is valued and how ecosystem services can be mainstreamed into planning. The overall objective of the project is to influence the approach to green asset management by assessing the extent to which GI has been valued by various stakeholders in the city-region, and by demonstrating ways to incorporate GI within government budgeting and planning processes. The project to supports Gauteng Provincial Government (GPG) planning with the uptake of a GI planning approach. In particular, the project provides insight into how to incorporate GI as part of the critical infrastructure trajectory that is being developed through the Gauteng Integrated Infrastructure Master Plan (GIIMP).


The project’s first deliverable was a report on the State of Green Infrastructure in the GCR (SoGI), published in 2013 (available for download here). This report assessed the physical state of GI in the GCR and whether municipalities have adequately appreciated and valued GI in their planning and budgeting processes. The SoGI provided:

  • Detailed spatial analyses of the extent, distribution and accessibility of green assets;
  • An indication of how ecosystem services provided by GI might be valued, through a review of international practice, and a case study of parks in Johannesburg;
  • An interrogation of how green landscapes are socially constructed, including an analysis of private and public decision-making processes; and
  • Photographic representations of GI in urban and rural landscapes in the GCR.

The SoGI report informed the subsequent phase of work, which was divided into two parallel tasks. The first was a set of expert studies on how to value ecosystem services and implement grey-green design solutions at the municipal level in the GCR; and the second was the GI CityLab - a strategic conversation with stakeholders in GCR about the role of public green asset data for ecosystem service valuations

The project’s second major deliverable was a report that assembled the insights from this second phase of work. This report, published in September 2016 provides ‘A framework for a GI planning approach in the GCR’, and presents the expert inputs as well as reflections from the GI CityLab discussions (available for download here). This second report builds on the foundations laid the SoGI report and establishes the importance of incorporating a GI approach in the GCR. It assembles expert inputs and reflections from collaborative stakeholder discussions in the Green Infrastructure CityLab to illustrate important considerations for the development of a GI planning approach in the GCR. It deepens the understanding of how GI can be embedded into municipal planning and decision-making processes, and proposes a framework for GCRO’s next phase of work on building a GI planning approach in the GCR.

The next phase of work will present a set of detailed investigative studies, which were drawn up based on stakeholder insights during the second phase of the project. These case studies further build the case for incorporating GI into municipal planning and infrastructure investment in the GCR, and will be incorporated into the GAI project’s third research report, to be published in 2017:

  • Investigating the requirements and possible methodologies for developing a green municipal asset registry to inform GI planning;
  • Exploring green infrastructure stormwater solutions for Diepsloot, Johannesburg; and
  • The cost-benefits of the Atlaspruit green infrastructure flood relief scheme, Ekurhuleni.

THE GREEN INFRASTRUCTURE CITYLAB

The Green Infrastructure CityLab was launched in January 2014. The CityLab facilitates the sharing and co-production of knowledge between provincial and municipal officials, as well as other stakeholders from a range of backgrounds. The CityLab provides the platform through which the GCRO explores existing GI plans and projects, and considers what is required to collectively build the knowledge base to support a GI approach in municipal planning processes.

UPDATES

The GI CityLab continues to be used as a platform to explore the investigative studies, and to guide the development of a GI planning approach in the GCR. The most recent CityLab session, which was held in mid-2016, provided an opportunity for stakeholders to engage around the investigative studies, which will be published in the third GAI report.

Various partnerships have been forged through the GAI project, including the Gauteng Planning Division, the Wits University Civil and Environmental Engineering Department, and UCL’s Department of Science, Technology, Engineering and Public Policy (STEaPP), a department that facilitates interactions between academic work in the fields of science and engineering and the world of public policy and decision making. Over the course of April and early May 2016, GCRO hosted Dr Carla Washbourne, a visiting researcher from STEaPP. Dr Washboune worked with Christina Culwick to investigate GCRO’s work on green infrastructure and its take-up in provincial and local government.

GCRO and STEaPP jointly hosted a side event at the Habitat III Conference, which drew on insights from the GAI project. The side event, entitled 'Shaping Informed Cities Platforms for Knowledge Generation and Use In Urban Decision-Making', was one of the Habitat III Urban Future events and was held on 19 October 2016. More details can be found here.

In line with GCRO's objective of enhancing the accessibility of research beyond academia, in March 2017 we released an explainer video on 'Green infrastructure in the Gauteng City-Region', which can be viewed on this page or at the following link.
