Research for this study was carried out under a two-year project to support the implementation of Ecosystem-Based Management (EBM) at two catchment-to-reef sites on Vanua Levu, Fiji, during which conservation planning approaches were trialled using EBM tools to evaluate options for re-designing marine protected area (MPA) networks. Current approaches in systematic conservation planning have focused on developing tools to maximize conservation benefits while minimizing socio-economic costs to users of a landscape or seascape area. In this study, we present a novel method for calculating the opportunity costs of conservation actions to multiple gear type users arising from fisher displacement due to the establishment of MPAs in Kubulau District, Vanua Levu, Fiji. The method builds upon those applied in land conservation in which the probability of land conversion to alternate functions is used to estimate opportunity costs to multiple stakeholders, which differs from previous approaches by providing information about costs of currently unused areas that may be of potential future benefit. We model opportunity costs of establishing a network of MPAs as a function of food fish abundance, probability of catch as function of gear type and market value of species. Count models (including Poisson, Negative Binomial and two zero-inflated models) were used to predict spatial distribution of abundance for preferred target fish species and validated against underwater visual census (UVC) surveys and biophysical predictor variables (reef type, reef exposure, depth, distance to shore, protection status). Spatial distributions of targeted fish within the three most frequently sighted food fish families (Acanthuridae, Lutjanidae, Scaridae) varied considerably: Lutjanidae had the highest abundance on barrier reefs; Acanthuridae on inshore fringing and patch reefs; and Scaridae on fringing reefs. Modeled opportunity cost, estimated as a function of abundance and probability of catch by gear type, indicated highest cost to fishers would arise from restricting access to the fringing reef between the villages of Navatu and Kiobo and the lowest cost would arise from restricting access to the Cakaunivuaka reef. The opportunity cost layer was added to Marxan models to identify optimum areas for protection to meet fisheries objectives in Kubulau’s traditional fisheries management area with: (a) the current MPA network locked in place; and (b) a clean-slate approach. The opportunity cost method presented here gives an unbiased estimate of opportunity costs to multiple gear types in a marine environment that can be applied to any region using existing species data.

The National Environmental Policy Act of 1969 requires federal agencies to examine the environmental effects of their proposed actions. On behalf of the Department of Defense, the Department of the Navy is preparing this Draft EIS/OEIS to assess the potential environmental effects associated with the proposed military activities. The Navy is the lead agency for preparation of this Draft EIS/OEIS. The Office of the Secretary of Defense directed the Navy to establish a Joint Guam Program Office that serves as the NEPA proponent of the proposed actions. A number of federal agencies were invited to be cooperating agencies in the preparation of this Draft EIS/OEIS. These agencies have either jurisdiction or technical expertise for certain components of the proposed actions or a potentially affected resource. The agencies that have accepted the invitation to participate as cooperating agencies are United States (U.S.) Fish and Wildlife Service, Department of Transportation Federal Highways Administration, Federal Aviation Administration, U.S. Environmental Protection Agency Region 9, U.S. Office of Insular Affairs, U.S. Department of Agriculture, U.S. Army Corps of Engineers, and U.S. Air Force.

2009
A rapid assessment of the environmental impacts of the 29 September tsunami was conducted by a multi-agency team from 3 to 14 October, 2009. Fourteen “green” and 10 “brown” environmental variables were selected and measured based on the experience of the survey team and similar reports from elsewhere. During a tour of the affected area on Upolu by car and on foot those “assessable” variables were scored “high” (over two thirds affected), “medium” (over one third, less than two thirds affected), “low” (less than a third affected) or zero (unaffected). Manono and Savaii were surveyed by air with the former showing evidence of some damage and the later apparently none or very little. The most affected areas in Upolu were villages in the Aleipata, Lepa and Falealili districts with the most obvious indicators of the tsunami’s impact being solid waste (sometimes resulting from the complete destruction of a village), erosion of the beach and fore-shore and the (expected) impact on marine resources. Other environmental variables assessed also showed similar patterns. Impacts on a wharf/dry dock facility are also described (including lost fuel drums) as are the possible environmental implications of new settlements created by displaced persons (mainly revolving around sanitation, drainage and water supply).
