Policy-oriented adaptation strategies for artisanal marine fisheries under climate and non-climate stressors in San Andres de Tumaco, Nariño, Colombia

Abstract

Climate and non-climate stressors significantly impact artisanal fishing in San Andrés de Tumaco, Nariño, Colombia, a crucial activity for local food security and employment. Our study aimed to prioritize these stressors on artisanal Fisheries Economic Units (FEUs) and propose policy-oriented adaptation strategies. We adopted an integrated approach, using diverse evidence sources and techniques such as complex network theory and Multi-Criteria Decision Analysis. Key challenges identified include reduced fish catch, abnormal climatic conditions, and changes in fish distribution. The community prioritizes educational, counseling, cultural, and behavioral adaptation measures. Crucial policy-oriented strategies encompass researching fish species' vulnerability to climatic changes, predicting commercial fish distribution considering climatic shifts, and developing a WebGIS for accessible regional climatic information; strategies that are consequently aligned with the Integral Policy for the Development of Sustainable Fisheries in Colombia. Our integrated approach assists decision-making, fostering adaptive capacity within these communities. It underscores the need for policy-driven, locally-sensitive, and strategic action to ensure the long-term resilience of artisanal fisheries against climate change and non-climate stressors.
