As the government agency responsible for conserving Taiwan’s terrestrial and freshwater biodiversity, our Branch has long collaborated with the Indigenous Amis Makotaay (Gangkou) Village in Hualien County, beginning with terraced landscape restoration in 2009 and biodiversity monitoring in 2016. Building on this foundation, in 2021 we partnered with National Dong Hwa University to conduct community-based resilience assessment workshops, aiming to gain a comprehensive understanding of sustainability challenges facing the Gangkou landscape–seascape. These workshops identified 43 priority issues requiring urgent action. In March 2022, we co-established the Gangkou Forest-River-Village-Ocean Initiative (Gangkou ILSA), along with its cross-sector, multi-stakeholder platform and action plan. Since then, the Initiative has advanced ocean-friendly farming, restored coastal wetlands, strengthened community-based ocean and forest patrols, documented Amis knowledge and culture, and developed innovative youth-led eco-tourism.
