This chapter aims to explore how an NGO, the Tse-Xin Organic Agriculture Foundation as an intermediary organization, was involved in the conservation and revitalization of socio-ecological production landscapes and seascapes (SEPLS). The case area is located on the outskirts of Yushan National Park and is surrounded by mountains. The case site is mainly inhabited by the Bunun, an Indigenous ethnic group. The Bunun’s relationship with the land has changed dramatically over the last century due to colonization and forced settlement. Farming patterns have also shifted from diversified farming in mountainous areas to single rice cultivation. This has resulted in the gradual disappearance of the traditional ecological knowledge (TEK) that values a harmonious relationship between humans and nature. The land management model has a direct impact on the quality of the habitat. For example, the irrigation system of rice fields is an important habitat for the rare medaka fish (Aphyocypris kikuchii). Since rice farmers are the primary managers of agricultural landscapes, their recognition and participation are essential in promoting the transition to organic rice farming and wildlife conservation. Therefore, the project team has sought ways to work with farmers to protect the rice field ecosystem and the habitat of the medaka fish, including organic farming, habitat creation activities, agrifood education programs, and integrating the payments for ecosystem services policy. Our findings suggest that an NGO as an intermediary group, acting as a knowledge translator in a multi-stakeholder platform composed of farmers, ecologists, tourists, local schools, government, and others, facilitated dialogue and understanding among stakeholders of the SEPLS. Indigenous and Local Communities (IPLC) also played a crucial role in facilitating community exploration of the balance between conservation and sustainable livelihoods.
