Coastline losses in the Sundarbans reaches 200 meters per year

FRISCO — Coastal development and climate change are eating away at the Sundarbans, the largest block of mangroves in the world, stretched along the coast of India and Bangladesh. In some areas, up to 200 meters of coast are disappearing annually, according to a report from the Zoological Society of London.
The losses are affecting the area’s natural protection from tidal waves and cyclones This will inevitably lead to species loss in this richly biodiverse part of the world, the scientists said.
“Our results indicate a rapidly retreating coastline that cannot be accounted for by the regular dynamics of the Sundarbans. Degradation is happening fast, weakening this natural shield for India and Bangladesh,” said ZSL’s Dr Nathalie Pettorelli, senior author of the paper. (more…)

Impacts could be much greater near estuaries, lagoons and river mouths

SUMMIT COUNTY — When it comes to sea level rise, not many countries have as much to lose as the Netherlands, so it should be no surprise that Dutch researchers are closely tracking the impacts of coastal erosion.
In one of the latest studies, scientists from UNESCO, the Technical University of Delft and Deltares say the effects of coastline erosion as a result of rising sea-level rise in the vicinity of inlets, such as river estuaries, have been dramatically underestimated.
Using a new model that incorporates input specific to coastal inlets like river estuaries and lagoons, the researchers found that most existing models show only about 25 to 50 percent of the coastal erosion that will occur as the climate warms and sea level continues to rise. (more…)
