8 At the national and sub-national levels, studies on development and risk scenarios capture specific challenges, for example, urban growth, demographic change, human health and ageing . In this regard, local scenarios of human vulnerability can inform future strategies for adapting to hazards such as heatwaves in cities under different socioeconomic development strategies. These scenario approaches allow us to focus on changes in climatic and societal conditions as well as urban transformations. This provides a more comprehensive basis for defining adaptation goals . Costs and benefits of different adaptation measures can be assessed against different future scenarios of climatic and societal change.
