Development of an adaptive marine ecosystem management and co-management plan at the Shiretoko world natural heritage site

摘要

The Marine Management Plan for the Shiretoko World Natural Heritage Site, Japan, provides a case study for adaptive marine ecosystem management and co-management of coastal fisheries. Shiretoko was the third World Natural Heritage Site registered in Japan and earned this title because of its (i) formation of seasonal sea ice at some of the lowest latitudes in the world, (ii) high biodiversity, and (iii) many globally threatened species. The natural resource management plan of the Shiretoko site is characterized by transparency and consensus building, because (i) UNESCO and IUCN require that the plan be sustainable; and (ii) the Government of Japan has guaranteed local fisheries that there will be no additional regulations included in the plan. The Marine Management Plan describes which species and factors are monitored, how these data are evaluated, and how the benchmarks specified by ecosystem management are determined. The Plan will provide a valuable example for the establishment of "environment-friendly fisheries" in Japan and other countries, because it includes voluntary activities by resource users that are suitable for use in a local context, flexible to ecological/social fluctuations, and efficiently implemented through increased legitimacy and compliance. This approach is appropriate for coastal communities where a large number of small-scale fishers catch a variety of species using various types of gear. We develop a method to evaluate fisheries integrity by catch and yield data. Keywords: adaptive management, co-management, scientific council, Steller sea lions, walleye pollock.
