The project aimed to conserve mangroves linking with sustainable livelihoods improvement in An Hoa lagoon through building capacity for local community, facilitation of allocating mangroves to community and piloting crab culture models in mangrove protection areas.
The area of mangroves in An Hoa lagoon is 65.82 ha. There are 18 mangrove species here, of which 11 are true mangrove species and 7 are mangrove associate species. Although the mangrove area is not large (only 3.5% of the lagoon area), it plays a crucial role in the protection of aquatic resources for the livelihoods of more than 6,500 households living in three communes around the lagoon. Local people exploit and harvest about 1,358 tons of aquatic resources (fish, shrimp, crab, clams, oysters) from this area annually.
According to local people, in the past the mangrove area around the lagoon was hundreds of hectares and mangrove species and aquatic resources were abundant. By 2011 however, the mangrove area was reduced and aquatic resources in the lagoon fell accordingly. Incomparison with 20 years ago, crab yields are reduced by 90% and shrimp yields have been reduced by 80%. This reduction was due to two main reasons:
The project was carried out in Tam Giang Commune where mangrove area remains large. In this area, local household incomes depended on fishery resources, thus mangroves were very important to their livelihoods.
- 180 members of MCC and 10 households conduct pilot crab culture models as direct beneficiaries.
- More than 6,500 households living in three communes around the lagoon as indirect beneficiaries.
1. Improved awareness of stakeholders (CPC and farmer) on mangrove roles.
2. Establishment of a pilot model of community based mangrove restoration and conservation linking with sustainable livelihood improvement.
3. Creation of a process for mangrove allocation by DPC to the community/village.
The CPC delayed allowing 10 households to establish crab culture models in the mangrove areas because they wanted to check that these areas were not under dispute among households. This contributed to the failure of the crab culture because the crab seeds were dispersed in April when the water temperature was too high for survival.
The juvenile crabs were too small and there was a lack of technical support from HUAF due to distant project management. The grantee relied too much on the experience and knowledge of the local community. The project should have had more consultations with aquaculture experts before operating a crab culture model.
According to local households, the absence of a flood season during this year caused scarcity of natural juvenile crabs. Thus, they were ultimately bought from another province, reducing their average survival rate.
