The coastal populations most at risk are those occupying low lying land. Populations in these areas will have no choice but to migrate further inland.

One reason for forced migration is that rising sea levels will result in the loss of agricultural lands due to permanent submersion, or to frequent flooding causing salinity of the water table and making the soil unproductive.

Economically, given that GDP per capita is generally above average for coastal populations and cities [Dasgupta et al., 2007] and that coastal areas are critical to international trade and commerce in today’s globalised economy, large disruptions to important port cities would have widespread ramifications. Alongside port infrastructure, inland infrastructures such as roads, railways and airports in low-lying regions are vulnerable to loss or damage [US EPA,2009]. Other industries important to GDP, in particular travel and tourism, would also be severely affected.

Rise sea level will necessarily have an impact on biodiversity, potentially leading to loss. Many species are specifically adapted for a particular type of coastal habitat and may be threatened if this habitat is affected by erosion, increased salinity, loss of wetlands,
mangroves and tidal marshes, more frequent flooding, etc [irgc.org].
