The mangrove forest is a forest types that live along the coast or a river estuary which influenced by the tide, which is inundated by sea water at high tide and free from puddles at low tide. Indonesian mangrove forest, filling 23% of the total area of mangrove forests of the world, with distrubution area widely spread, types and different characteristics. The mangrove ecosystem has many important functions, including as a life support system, a source of food, stabilize the coastline, reducing erosion from storm surges, currents, waves, and tides and contribute as controlling global climate through carbon sequestration. In addition, the intricate root system of mangroves also makes these forests attractive to fish and other organisms seeking food and shelter from predators. Mangrove forests are under threat from many development pressures: overharvesting, pollution, conversion for agriculture, aquaculture or urbanization, oil and gas industry and development of infrastructure. Therefore this ecosystem are need the protection, conservation and sustainable use for the welfare of society.
After the 2004 Indian Ocean tsunami, the importance of mangroves became widely recognized. Since then, mangrove planting has become very popular, with governments, NGOs, private sector, students, religious leaders and newlyweds planting mangroves or raising funds for others to plant.The territorial contex of mangrove forests area in Banda Aceh were in good condition, but there are in conditions that are needed attention. One of the coastal villages in Banda Aceh, Alue Naga was lost 80% of its citizens and landscape level in entire villages into the water. Before the tsunami, there were 6.331 villagers who work as fishermen and oyster seekers that were lived in 4 sub-villages. After the tsunami, the population were 1,270 people with social- economic struggle to stay on and live off the sea around. Alue Naga coastal communities depend on the sea as a source of major economies. Planting of mangroves have been done in 2015 with the aim to prevent the effects of abrasion and impact of other disasters and to support the economic empowerment of oyster farmers. However, most of the mangrove die due to the management and treatment is not done right by the local community. This makes the Natural Aceh team moved to make an improvements of coastal ecosystem by replanting mangroves to reduce the impact of disasters in the Alue Naga village, therefore will provide great benefits for farmers oysters, because seed oysters will be attached to the trunks of mangrove or other substrates that are around the mangrove ecosystem.
Local communities are important to be involved directly then can improve the welfare of coastal communities. Moreover, it also implies that the concepts of local (indigenous) on the ecosystem and its preservation should be fostered and promoted as far as it can support this programme. Resolving the problem of mangrove forest destruction in Alue Naga, requires the cooperation of many participant to continue to make efforts in improving rehabilitation of mangrove forests. Surely, to make the efforts are needed the organizational education media, awareness and act as a real answer all the issues on environmental damage caused.
