Green and grey infrastructure | State of Gauteng City Region

Municipal green asset typologies dissect urban land cover per municipality to represent the distribution of green assets across Gauteng. The graph indicates that 'planted and natural grassland' are dominant features across Gauteng’s ten municipal landscapes, with larger shares of grassland predominating in less urbanised municipalities, such as Mogale City and Merafong.

'Urban' land cover classes are not the only transformed features of the landscape and may represent a changeover from one land cover class to another. This is evident in Lesedi, where 41% of the landscape is categorised as planted and natural grassland and cultivated.

Green infrastructure can be understood as an interconnected set of natural and man-made ecological systems, green spaces and other landscape features that together form an infrastructure network providing services and strategic functions in the same way as traditional ‘hard’ infrastructure.

In same way as we view roads, bulk water and sanitation networks and electricity distribution lines comprising a network of infrastructure utilities; natural or vegetated features are part of the infrastructure networks that provide services to society.
