Coastal wetlands under threat from sea level rise, says World Bank

Climate change induced sea level rise of one metre is likely to destroy 60 per cent of the developing world's wetlands says a new World Bank research working paper. The economic loss of these wetlands is estimated at approximately $630 million US dollars per year.

The World Bank study looked at the risk to coastal wetlands in 76 countries at a sea level rise of one metre. Because there are so many uncertainties with the rate of sea level rise, the one metre level was chosen to study the likely impact. This sea level may be achieved this century, with sea level rising 60% faster than IPCC projections. Sea level rise is unstoppable, but it can be slowed through emissions reduction and give us humans and ecosystems a chance to adapt. Sea levels will continue to rise for several centuries.

Planners need to allow for Coastal wetlands migration due to sea level rise, climate change

Coastal Wetlands are under pressure. They face rising seas from climate change, but their biggest obstacle to migrate naturally inland is human development with roads, houses and other infrastructure blocking their way. And our urban planners are largely unaware of this tricky situation.

New study estimates economic value of wetlands conservation

What value our wetlands? How do you value a wetlands environment? How do you value the indirect ecosystem and biodiversity benefits of having healthy wetland environments? An economic study of the Hattah wetlands within the Hattah-Kulkyne National Park in northern Victoria attempts to answer these questions putting a direct economic value of $14.5 million dollars per year for maintaining the Hattah Lakes in a healthy state with adequate water levels.
