The City of Johannesburg wants to protect nature and ecosystem services, improve air quality, raise environmental awareness and better manage water and waste. We are supporting the city to achieve this by drawing on our wide-ranging climate, nature and urban systems expertise. Through this work, we are gaining a clearer understanding of the challenges facing the city and cities like it. This co-learning approach allows us to learn from them as much as they are learning from us. We share these learnings during monthly co-learning sessions and the co-production of plans, strategies, tools and campaigns.
