The need for (which) adaptation to climate change in cities?

With hundreds of cities declaring climate emergencies, there is little evidence about successful climate adaptation and its upscaling. In parallel to the case for adaptation, there is also a distinct need to mitigate climate change, reducing greenhouse gas emissions. Exploring synergies and trade-offs between adaptation and mitigation, a third concept – resilience (and resilience thinking) – is a perspective that can scrutinise adaptation and tie it to mitigation. Which adaptation, to what, and how do we measure the success or fallacy of adaptations to climate change in cities?
