Chapter 3: - Exposure to Climate-related Hazards in Cities: Current and Future Trends

The scope of this analysis is not to review that have been set.6 This section of the chapter articulates the exposure past and future risk engendered by climate change in cities, but rather to data gap and the international frameworks and methodologies that are focus on the urban exposure to climate hazards. [...] Throughout the analysis in this chapter, the primary focus A key enabler of the data presented in this chapter is the deployment of a is on cities within this definition, though the data are cross-compared harmonized international definition of urban areas, called the Degree of with those for towns and semi-dense areas as well as rural areas to give Urbanisation (Box 3.1). [...] ssp434 Besides the above considerations on the location and distribution of ssp370 exposed people, Figure 3.15 shows how the share of the population living in cities exposed to a change in climate type by 2040 varies by SSP ssp245 and across regions: ssp126 At the global level, the share of the urban population (as of 2025) ssp119 exposed to a change in climate type change would range from 13 per. [...] Most of the cities that have a very large share of the Zealand, and Oceania, the share of population exposed to riverine population exposed to riverine flooding are located along some of the flooding is similar for all three degrees of urbanization, meaning world’s biggest flood plains, shaped by rivers like the Nile, Tigris, Indus, that rural areas and cities in these regions are similarly expose. [...] Attributes and characteristics of the exposed population Sustainable Cities and Human Settlements71 and other efforts to such as demographics, health, cultural and behavioural traits, levels of support the integration of open, free geospatial data for common areas awareness and information available, insecurity and deprivation can all of analysis, like the cities in this chapter.
