The initial cost for mangrove reforestation in the Philippines is high, at about Php26,000 per hectare and would entail an annual maintenance cost. However, coastal protection provided by mangrove forests will save millions of pesos of possible damages if an extreme hazard event occurs. Livelihood would also improve upon the growth of mangrove forests due to increased productivity in the area which would enhance fisheries. It could also provide for timber and wood fuel [3][4].

In order to secure the success of mangrove reforestation, the following should be prepared: a detailed study on the tree species used, site investigation, a good method design, and a conclusive management plan. Failure in mangrove afforestation is attributed to the use of wrong tree species, improper evaluation of site, and the lack of space for inland migration of the mangroves. Due to the lack of space, most mangroves are planted in deeper waters where they could thrive but will eventually encounter difficulty in coping with sea level rise [2]. The site chosen should have enough space from the coast to urban infrastructures for inward migration. Otherwise, there is a need for assisted migration and replanting to a different area which would entail additional costs [3].

There is a difficulty in implementing this solution due to the availability of land and competing land uses [1][3].

Increase in mangrove population would prevent coastal erosion, increase water quality by trapping contaminants in the root network, and increase productivity and biodiversity [3].
