      abstract = {Krabi River Estuary, a ramsar site located in southern  Thailand, is dominated by two major natural vegetation  assemblages, i.e. mangrove forests and seagrass beds.  According to the cluster development strategy, the cabinet  has approved in principle to develop Krabi as the global  marine tourism center and economic gateway of Asia. This  study aimed to assess the economic value of the site, using  market price and benefit transfer. The impact on economic  activities with the 5% annual decline of mangrove forests  was evaluated. The estimated annual use value of the site  was $9.7 million for recreation and tourism. The economic  value of mangrove forests was $758/ha. The net present  value of mangrove forests was $73.1 million based on 7%  discount rate and 15-year time line. An approximate impact  of mangrove change follows the study of Ruitenbeek (1992).  It was assumed that the impact on local direct resource  extraction and loss in biodiversity would occur at the year  after the depletion of the forest. The impact on the  productivity of local fishery would occur in the fifth year  and on tourism in the tenth year. Thus, value loss of  mangrove at the annual rate of 5% in the net present term  became $21.0 million or $2.3 million per year. The results  imply that a development project that causes the same rate  of mangrove destruction must generate a least an income of  $2.3 million per year to be considered as an economically  feasible project.},
