Green Talks LIVE: Boosting African cities’ resilience to climate change: The role of green spaces


‌‌The OECD Green Talks Live webinar series brings experts together to discuss pressing environmental issues. For a global audience, these free webinars are open to the general public and participants are welcome to pose questions during the Q&A segment. Video recordings of our Green Talks are made available online afterwards.

Register for an upcoming webinar or watch the video recordings of our past webinars below.


African cities face two key transitions: urbanisation and climate change. How can African cities urbanise resiliently and sustainably, and ultimately – be liveable? Green spaces are one lever action at the disposal of cities, which are often overlooked and underappreciated in the competition for land when urbanising.

What are the dynamics between green spaces and urbanisation in African cities? What is the potential for green spaces to boost resilience to extreme weather, like heat waves, and cities’ sustainability, such as pollution regulation?

On 5 July, Brilé Anderson from the OECD SWAC Directorate and Dr. Jorge Patiño from Peak Urban at the University of Medellin, along with other experts, discussed these trends, the potential role that green spaces can play in the future of African cities, and what lessons can be learned from other parts of the globe.

The presentation was be based on the forthcoming OECD study on green spaces: Boosting resilience in African cities: Role of green spaces.

VIDEO REPLAY & PRESENTATIONS - LAUNCH OF THE Global Plastics Outlook: Policy Scenarios to 2060

Plastic pollution is one of the great environmental challenges of the 21st century, causing wide-ranging damage to ecosystems and human health. With a growing global economy and population, global plastics use is projected to nearly triple by 2060 from 2019 levels. Plastic leakage to the environment is also projected to double, with stocks of accumulated plastics in rivers and oceans projected to more than triple by 2060. Achieving the global goal of eliminating plastic pollution to prevent worsening impact to the environment and human health requires shared objectives and co-ordinated efforts at the global level.

What comprehensive measures can countries implement to combat this growing plastics issue? What policy packages can target all phases of the plastics lifecycle? What action can be taken at both the regional and global level?

On 21 June 2022, experts explored these questions and more during a presentation of the OECD report Global Plastics Outlook: Policy Scenarios to 2060. The report provides a set of coherent projections on plastics to 2060, including plastics use and waste as well as the environmental impacts linked to plastics, especially leakage to the environment.

The webinar included a presentation of the key projections and two policy packages to bend the plastic curve, for a better understanding of the environmental benefits and economic consequences of adopting more stringent policies.

VIDEO REPLAY & PRESENTATIONS - launch of the Global Plastics Outlook: economic drivers, ENVIRONMENTAL IMPACTS AND POLICY OPTIONS

While plastics are extremely useful materials for modern society, plastics production and waste generation continue to increase with worsening environmental impacts despite international, national and local policy responses, as well as industry commitments.

How can government policies respond to the urgent need to help make the lifecycle of plastics more circular? How can the expansion of national policies and improved international co-operation help mitigate environmental impacts all along the value chain?

On 22 February 2022, our experts explored these questions during the launch of the Global Plastics Outlook: Economic Drivers, Environmental Impacts and Policy Options. This Outlook is the first report to comprehensively take stock of current plastics production, use and waste generation, uncover the underlying economic drivers and map the related environmental impacts on a global level. The report intends to help decision-makers understand the direction in which we are heading and assess which policies can support a more sustainable and circular management of plastic materials.

The webinar included a presentation of the key findings and four key levers that are essential to bend the plastics curve: markets for recycled (secondary) plastics, technological innovation in plastics, domestic policy measures and international co-operation, including international financing.
