How does C40 define 'urban adaptation'?

C40 defines 'urban adaptation' as managing changes to mitigate the adverse effects of climate change in cities. This definition emphasizes the proactive approach cities must take in response to the changing climate, which can manifest in various ways, such as rising temperatures, increased flooding, and unpredictable weather patterns. Urban adaptation strategies might include enhancing green spaces, improving drainage systems, and retrofitting buildings to withstand extreme weather.

This focus on management and mitigation reflects the reality that cities are not only places of significant carbon emissions but also areas that must prepare for and adjust to the impacts of climate change. The aim is to protect urban populations, maintain infrastructure resilience, and ensure that essential services continue to function effectively in the face of climate-related challenges.

Given this context, the incorrect options do not capture the comprehensive nature of urban adaptation. Expanding urban areas might increase the vulnerability of cities to climate risks, building more infrastructure alone does not guarantee that it will be resilient to climate impacts, and reducing population density does not inherently address the need for cities to adapt to climate change effects. Therefore, the definition that encompasses both the need for management and a focus on mitigation of adverse effects aligns perfectly with C40’s objectives.
