Environmental policy narratives and urban green infrastructure: Reflections from five major cities in South Africa and the UK

Abstract

In the context of large and growing urban populations, there is a pressing need to understand how the urban environment can be sustainably planned, developed and maintained for greatest benefit to people and nature. The use of ‘green infrastructure’, as a framing approach for integrating urban green space into urban decision-making claims significant international impact. This paper describes key urban environmental policy narratives of five different urban areas (Cape Town, Durban (eThekwini) and Johannesburg in South Africa and Birmingham and London in the UK) reflecting on the way that they have brought green infrastructure concepts into their decision-making. This multi-method study includes analysis of academic papers, technical reports and policy documents and semi-structured interviews with academics, practitioners (planners, engineers, environmental consultants), policy-makers and local community actors. This work has highlighted significant differences in the explicit use of urban green infrastructure as a framing within environmental policy, shaped by the mix of biophysical, social and economic factors that dominate the policy priorities of each city. It adds to a growing evidence base from research and practice aimed at supporting effective urban environmental policymaking.
