About this Discussion

Urban centres provide opportunities for a range of social and cultural activities, as well as being critical for innovations in science, technology and education. They are also of critical importance for social and economic development. However, with approximately 40% of global energy use taking place within city buildings, this sector is also the single largest contributor to global greenhouse gas emissions.

As a result, the design and use of energy and resource-efficient buildings has a key role in climate change mitigation to accelerate the global green economy transition. Although vast savings are possible by constructing new green buildings and retrofitting existing buildings, even greater gains can be achieved by adopting a long-term life-cycle approach involving stakeholders at different stages – from environmentally-minded investors and architects, to sustainable extraction, construction and usage, and the eventual demolition and the recycling or disposal of the building materials.

Cities are well-placed to play a major role in decoupling economic development from resource use and environmental impacts, while finding a better balance between social, environmental and economic objectives. Resource-efficient cities combine greater productivity and innovation with lower costs and reduced environmental impacts, offering at the same time financial savings and increased sustainability.

Africa is one of the most rapidly urbanising continents and its urban transition is a key global game-changer: the way African cities develop will determine whether or not we achieve global climate mitigation targets, Sustainable Development Goals (SDGs), biodiversity, poverty and inequality targets, and resource sustainability.

The Urban Natural Assets (UNA) programme was designed to support local governments in Africa in addressing the daily challenges they experience around protecting and revitalising their urban natural assets whilst building climate resilience.

By 2100, sea levels are expected to rise by almost seven feet in the Bay Area. New research shows how traditional approaches to combating sea-level rise can create a domino effect of environmental and economic impacts for nearby communities.

This research shows how seawalls constructed along the San Francisco Bay shoreline could increase flooding and incur hundreds of millions of dollars in damages for communities throughout the region. The researchers emphasize how non-traditional approaches, like choosing to flood certain areas of land rather than build walls, are smarter, more sustainable solutions for the Bay Area and similar coastal bay communities.
