Climate Risks and Vulnerabilities in Coastal Communities in Salon 6
11:00 - 12:30
Currently, 48% and 71% of the infrastructure for Mombasa and Lamu islands In Kenya respectively falls within the Low Elevation Coastal Zones (LECZ) of less than 10m thus highlighting their extreme vulnerability under the pessimistic sea-level-rise (SLR) scenario (Ochanda, V;2017). In Rio de Janeiro, for example, an analysis on the city vulnerability by the 2080s indicates that almost 7.7% of the city area is highly vulnerable to impacts of climate change (Mandarino; F 2017). The case is not very different from Buenos Aires where more than 90% of the population is living in urban agglomerations, with a temperature increase on 10C posing a threat to the highly urbanized city hence heightening the delicate balance and importance of climate change adaptation in cities (Camillioni, C;2017). The challenges in cities to impacts of climate change are exacerbated by populations living in these cities. The simulation findings for Mombasa city indicate that exposure level to the 1:100 storm surge at 4m elevation falls between 433,300 and 2.5 million people and over US$9.1 billion in assets exposed by 2090. Under RCP 8.5 (pessimistic-scenario) for Lamu Island, the exposure level of between 37,200 and 480,400 people and over US$ 648 million in infrastructure/assets exposed by 2090. This, therefore, means that the planning of cities and its development control are key in climate change adaptation, mitigation as well as protecting infrastructure from these cities from impacts of climate change.
