Mangrove deforestation

Mapping and monitoring mangrove loss
Mangroves are a highly threatened ecosystem, as they are converted into other uses such as aquaculture and agriculture.  In the Mangrove Lab, we've been mapping mangrove deforestation throughout Southeast Asia. We've mapped it in particular countries, especially Myanmar. In the Ayeyarwady Delta, we showed rapid mangrove loss due to rice agriculture. We also worked with Fauna and Flora International (FFI) to map mangrove change in Tanintharyi from 1978 to 2014. We've also studied small scale mangrove loss patterns in Madagascar.

We also work at the regional level. We have shown that mangrove loss in the whole of Southeast Asia is lower than previously thought, and that oil palm is an under-recognized but important driver of mangrove deforestation in the region.
