The study discusses strategies and pathways that may be useful when considering community-wide GI deployments. Based on interviews, field surveys, observations of field programs, and literature surveys on GCC and NYC's Department of Environmental Protection, this paper clarifies the city's GI policy, the characteristics of the study area, GCC organizational structure, GI implementation and maintenance, related volunteer and education programs, and the design process of the area master plan. Conclusions of this paper are as follows: GCC involved various stakeholders, implement various GI reflecting local characteristics, and maintained it; Various programs according to the characteristics of the participants were developed to create various participation opportunities; As a local community group who connects institutions and projects, GCC implement GI according to local conditions.

This article examines how a community of oyster farmers in Hokkaido, Japan recovered from the 2011 Tōhoku Earthquake and Tsunami, which damaged their aquaculture in Lake Akkeshi. It focuses on how, over the years, nested governance structures facilitated iterative learning, which helped build resilience against unexpected external crises. Drawing on adaptive management and resilience studies, this study examines the historical development of the local fishery cooperative association (FCA) as a series of responses to socio-ecological disasters — responses that this article characterizes as iterative learning. During the recovery after the 2011 tsunami, the FCA functioned as an information hub that directed the flow of knowledge and resources through government and industrial hierarchies, to the benefit of the farmers. This research, conducted between 2015 and 2017, is based on interviews with farmers, cooperative administrators, and government officials, as well as an analysis of archived records, fishery regulations and post-disaster subsidy programs.
