Asia is most affected
Major coastal cities and/or areas with major river deltas where dense populations live and agriculture is productive are most at risk from sea level rise. Most of these areas are in Asia.
Population, area and economy affected by a 1 m sea level rise

According to the United Nations
Environment Program UNEP, "Even for today's socio-economic
conditions, both regionally and globally, large numbers of people
and significant economic activity are exposed to sea-level rise.
The densely populated megadeltas are especially vulnerable to
More than 1 million people living in the Ganges- Brahmaputra, Mekong and Nile deltas will be directly affected simply if current rates of sea level rise continue to 2050 and there is no adaptation. More than 50 000 people are likely to be directly impacted in each of a further nine deltas, and more than 5000 in each of a further 12 deltas.
Some 75 per cent of the population affected live on the Asian megadeltas and deltas, with a large proportion of the remainder living on deltas in Africa. These impacts would increase dramatically with accelerated sea level rise."
Impact closer to home
The Pacific includes the smallest and lowest lying nations in
the world. These nations have a high population density, which
means they are extremely vulnerable to sea level rise.
Many Pacific nations are already feeling the effects of sea-level rise. Without immediate action, these problems will become widespread throughout the Asia-Pacific region, including Australia.
