Revealing both positive and negative economic impacts directly received by community is notable in order to provide an overview of a natural resource management performance. Tanakeke Island is known as one of the important mangrove ecosystems in South Sulawesi Province which is facing serious degradation problem due to the unwise utilization by the local. As a result, there is a loss that must be borne by the community since their mangroves has severely degraded. This study aims to identify and estimate the benefits and losses experienced by the Tanakeke community as a consequence of existing mangrove utilization. Primary data were collected through questionnaire interviews to a number of respondents and in-depth interviews with key persons. Respondents were selected using snowball sampling technique while the key persons purposively determined was considered to have a good understanding of mangrove management conditions in Tanakeke Island from government, private and NGO groups. The collected data then analyzed using economic valuation techniques, namely productivity approach, market price approach, loss of earnings approach, prevention cost approach, and replacement cost approach. The results shown that mangrove is currently used primarily for: aquaculture ponds, charcoal, firewood, and  fisheries around mangroves. Each type of utilization generates approximately IDR22,286,800 for ponds, IDR17,666,667 for charcoal industry, IDR495,000 for firewood and IDR22,255,741 for fisheries each per person per year. Unfortunately, damaged mangroves may allow several undesirable conditions to occur that cause harm to the community. Conditions considered to be disadvantageous to the community are tidal, abrasion, storms, sea water intrusion, and loss of  aquatic habitat for coastal biota. Estimated losses arising from each of these conditions in the last 12 months were: abrasion of IDR4,500,000, storms of IDR255,000, high tide of IDR4,000,000, sea water intrusion of IDR1,629,688 and loss of nursery ground area of IDR1,813,214 for each suffered individual.
