Ecological reclamation process

The ecological reclamation process starts from the reduction of wave intensity by constructing eighty triangular units of floating breakwater connecting as a line, located 2km away in the sea. Three lines of bamboo trap, building layer by layer, along the shoreline helps absorbing wave energy and trapping sediment for mangrove afforestation. The shrimp farm ridges are gradually demolished, allowing seawater to go through the inland. Natural water flow helps preventing water pollution. Reforestation process then begins on the abandoned shrimp farms. Once the forest grows, the afforestation process can be done along the shoreline where sediments have been returned. Within the next 30 years, when mangrove forests become a natural buffer, floating breakwaters can be removed from the coastal ecology.

Structural innovations to reduce wave intensity, trap sediment, and building on soft clay

The galvanized-trusses form a triangular unit of floating breakwater in the sea, which is best form absorbing wave energy. The structure of the pontoon with metal grille and net increases friction forces of the waves. Without a foundation and disassembling structure, the impact on marine ecology is minimal. It is also used as a fish cage and trap as well as shelters for fishermen. A zigzag ecological trail made from bamboo acts as layers of sediment trap on the shoreline. It connects to a clam embryo shelter which is a mangrove-wood wedge and disassembling structure. To minimize footing, 60-degree columns to the ground that mimics bracing roots of mangrove are used with a wide-span cable structure. The biodegradable materials allow architecture to decompose and be a part of nature in 30 years.

Mechanism sustaining coastal ecology and local economy

The decreasing number of aquatic animals in the sea has affected the productivity of local fisheries. This is a consequence of the absence of mangrove forests which has an impact on the animal life cycle in the ecosystem. Hence, clam and mangrove-crab shelters are built to culture embryos and return them back to nature. This operation helps to complete the food chain in the coastal ecology yielding sustainability for local fisheries in the long term. Besides, the outdoor terrace inspired by local “sun-dried krill litter “can be used as a relaxing space for fishermen and tourists. Ecological trail and observatory tower enabling biodiversity experiences together with vernacular architecture are parts of eco-tourism promotion in this area, which will ultimately stimulate the local economy.
