Abstract

Climate change is reshaping Peru’s marine–coastal ecosystems and increasing the vulnerability of artisanal fisheries and aquaculture. The aim of this study was to critically synthesize recent evidence related to the ecological and socioeconomic impacts of climate change on both sectors and to identify adaptation strategies and their main constraints. A systematic literature review was conducted following the PRISMA 2020 guidelines, including a search of international and regional databases, explicit eligibility criteria, and a narrative thematic synthesis. The results show consistent patterns of shifts and variation in species availability, risks associated with sea-level rise, and increased exposure to extreme events, affecting catches, livelihoods and food security. These impacts are amplified by non-climatic pressures —such as overexploitation and selective fishing— which reduce the recovery and adaptive capacity of marine populations. The evidence reviewed also identifies recurring responses: adaptive and ecosystem-based fisheries management, the strengthening of conservation areas, productive diversification, technological innovation, climate-resilient aquaculture, and environmental education for capacity building. However, the effectiveness of these measures is dependent upon how well persistent barriers are overcome, particularly institutional fragmentation, weak science–policy integration, and limited community inclusion in adaptive governance. In conclusion, we found that the requirements for marine–coastal sustainability call for integrated approaches that prioritize climate resilience, monitoring, participation and territorial planning.
