In response to the threats in mangrove resources such as massive fishpond conversion, industrialization,and increased human settlements in coastal areas, the province of Guimaras answered these threats bywidespread mangrove reforestation projects in its coastal communities. These projects were found outto be beneficial, as depicted on large gap on the mangroves overall benefits and the costs of implementationof the mangrove reforestation project. Results of the study show that the present total benefit of mangroveper hectare with sustainable harvesting in the first year is lesser than the costs. However after the firstyear, the net benefits are positive. However, in compliance with Republic Act 7161 (R.A. 7161) thatbanned the cutting/using of all mangrove species, cost-benefit analysis of mangrove reforestation withoutharvesting was also computed. The net benefits exceed the costs from the start of the year up to the 20thyear. Both the scenarios include the Mean WTP equivalent to PhP 142.75, which is the amount peopleare willing to give for the conservation of mangroves. The net present values (net benefits) of mangrovereforestation were found positive for both scenarios: with sustainable harvesting and without harvesting.
