The objective of the ECOBAS project was to provide the coastal people of Bangladesh with an alternative approach for adaptation to coastal erosion and flooding. By using the concept of “eco-engineering” the natural resistance of shellfish reefs against hydrodynamic forces reduces human vulnerability to coastal erosion and flooding, and delivers a source of aquatic food. ECOBAS stands for ECO-engineered Coastal Defence Integrated with Sustainable Aquatic Food Production in BAngladeSh, and was executed by a multidisciplinary team of Dutch and Bangladesh research institutes (Institute of Marine Sciences, CU). The ECOBAS project was funded by Partners for Water. Also the Embassy of the Kingdom of the Netherlands financed extra monitoring activities in the second phase of the project which enabled generation of more data and a broader understanding of the research.
