HEALTH takeawayClimate change likely to exacerbate existinghealth risks in cities and create new ones Heatwave exacerbates existing health risks
of poor amp elderly in NYC July 4-6 1999
High Existing Health Risks Kibera NairobiSource Shagun Mehrotra 2003
Risks1 Large city and high density amplify health risks2 Increase in poor and elderly populations compoundsthreats of heat and vector-related illness3 Cities with limited existing services at greater risk of
drought and vector-related illnessesAdaptation and Mitigation strategies 1 Passive approaches mdashtree planting green roofspermeable pavements mdashto reduce urban heat island2 Improving and increasing water and energy services3 Regulate settlement growth in flood plains4 Expand health surveillance and early warningsystems mdashtechnology and people buddy systems
