It is often stated that mangroves provide significant value in the coastal zone as a buffer against erosion, storm surge and tsunamis. While there is some attenuation of wave heights and energy as seawater passes through mangrove stands, it must be recognised that these trees typically inhabit areas of coastline where low wave energies are the norm. Therefore their capacity to ameliorate high energy events like storm surge and tsunamis is limited. Their long term impact on rates of erosion is also likely to be limited. Many river channels that wind through mangrove areas are actively eroding stands of mangroves on the outer sides of all the river bends, just as new stands of mangroves are appearing on the inner sides of these same bends where sediment is accreting.

trip to toubacouta, senegal
-
little village north of the gambia.
mid september 2006. we went there to camp out with some university students that lived near the village, and to experience some of the "cultural traditions" that senegal is known for: lutte (form of wrestling), the mangroves, clearing fields while running from the concuran, etc. all in all, it was a very educational four days. and man, did we eat a lot.
