|a This paper presents a first estimate of the exposure of the world’s large
port cities (population exceeding one million inhabitants in 2005) to coastal flooding
due to sea-level rise and storm surge now and in the 2070s, taking into account
scenarios of socio-economic and climate changes. The analysis suggests that about 40
million people (0.6% of the global population or roughly 1 in 10 of the total port city
population in the cities considered) are currently exposed to a 1 in 100 year coastal
flood event. For assets, the total value exposed in 2005 across all cities considered is
estimated to beUS$3,000 billion; corresponding to around 5% of global GDP in 2005
(both measured in international USD) with USA, Japan and the Netherlands being the countries with the highest values. By the 2070s, total population exposed could
grow more than threefold due to the combined effects of sea-level rise, subsidence,
population growth and urbanisation with asset exposure increasing to more than ten
times current levels or approximately 9%of projected global GDP in this period. On
the global-scale, population growth, socio-economic growth and urbanization are the
most important drivers of the overall increase in exposure particularly in developing
countries, as low-lying areas are urbanized. Climate change and subsidence can
significantly exacerbate this increase in exposure. Exposure is concentrated in a few
cities: collectively Asia dominates population exposure now and in the future and
also dominates asset exposure by the 2070s. Importantly, even if the environmental
or socio-economic changes were smaller than assumed here the underlying trends
would remain. This research shows the high potential benefits from risk-reduction
planning and policies at the city scale to address the issues raised by the possible
growth in exposure. |
