Identifying Linkages Between Climate Change, Urbanisation, and Population Ageing for Understanding Vulnerability and Risk to Older People: A Review

The present century faces developmental fallout as vulnerability and risk mount on the global systems due to climate change, urbanisation, and population ageing. Moreover, population ageing is gaining a stronger hold in urban areas, and so are climate change and related shocks and stresses. Consequently, repercussions for the weakest sections of society – including the elderly – remain under academic consideration. In this context, the paper aims to understand the perilous predicament of older people due to the occurrence and interaction between climate change, urbanisation, and population ageing. This review investigates the underpinnings of the nature of the interaction among the three phenomena; and discerns how as a result of the interaction, various climate change related shocks and stresses affect older people in urban settings. It emerges that these three phenomena exhibit: concurrence; a positive trend of growth; and a cyclic pattern of interaction with four linkages, implying (i) rapid urbanisation is fuelling climate change, (ii) climate change is impacting urban areas, (iii) older people are increasing in urban areas, and (iv) urbanisation provides opportunities and barriers for older people. This interplay further discloses that older people stand vulnerable and at heightened risk from climate change related stressors in urban areas. These understandings highlight the need to ensure that urban environments remain age-friendly even in the face of climate change.
