economic value by type

The economic value of most wetlands are not known and therefore not included in decisions regarding wetland use, conservation or restoration…

According to the already mentioned 2004 WWF report:
  • unvegetated sediment wetlands (for example inter-tidal sand and mudflats such as the Dutch Wadden Sea or the Rufiji delta in Tanzania) are found to have the highest economic values,


  • followed by freshwater wooded wetlands (for example temporarily inundated floodplain forests and swamp forests).
Median wetland economic value (MWEV) by wetland type*
wetland type MWEV US $ ha/
year (2000)
un-vegetated sediment 374
freshwater wood 206
salt/brackish marsh 165
freshwater marsh 145
mangrove 120


* Note that rivers and floodplains are not included in this study and that reported data are based on the sample of 89 case-studies corresponding to about 63millions ha.
