5. The services and goods of mangrove ecosystems
Supporting services (soil formation, photosynthesis, primary production, nutrient cycling and, water cycling)
Provisioning services (are the natural products generated by mangroves, such as wood, habitat for honey collecting, wildlife…)
Regulating ecosystem services (such as resilience, pollination, biological control, nutrient cycling, air quality regulation, and maintenance of biodiversity)
Regulating services (include water quality maintenance, environmental disturbance prevention (storm, flood and erosion control), and climate regulation

We have seen that mangrove ecosystem, as part of the coastal zone is important because, it offer us:
Protection, and therefore security
Food supply, and therefore health
Mitigation of climate, and therefore the future
Employment (fisheries, tourism, among others
Land accretion, (additional space for biodiversity, storage of water)

18. Project Objective
The main objective of this pilot project is to develop adaptation measures against sea level rise, and hence addressing climate change in a sustainable way. The adaptation measure include e.g. establishing of a sedimentation trapping unit aiming to demonstrate the mitigation of the coastal erosion.

32. Conclusion The process of establishing the STU is very instructive
The Construction of the STU is finished
The project is finalized within the given time duration
Four students are writing their BSc thesis on different topics of this project
Data gathering is started and will be continued
Participants, including volunteers have gained in-depth knowledge of the STU and its functioning
Several media publications have been issued

33. Points of improvements
Transportation in the STU; suggestion: to use an airboat (time effective, fast and easy)
More people to engage actively; compensation is required

34. Points of concern Monitoring
Addition of filling material (additional branches, bamboo’s etc.)
Life time of such materials
The rate of compaction
