The module focuses on the impacts of sea level rise on mangroves and tropical wetlands. The current and forecast rates of sea level rise (SLR) and variation of rates across the globe will be discussed. Sea levels are expected to rise because of the impact of climate change ; this is predicted to have negative impact on mangrove forests. The module continues to outline the global threats to mangrove forests, the mechanisms that allow mangroves to keep up with SLR and monitoring of wetlands for resilience to SLR. The methods of mangrove accretion measurement are also described. Mangroves provide many valuable ecosystem services, but are threatened by climate change. Therefore, monitoring should take place that can identify which mangrove can keep up with SLR and should be protected.
