Abstract

Aquatic food systems deal with numerous problems as a result of climate change, including changes in temperature and precipitation, warming and acidity of the ocean, altered ecological dynamics, and an increase in the frequency of extreme weather events. Rising temperatures, rising sea levels, toxic algal blooms, acidification of the ocean, and more powerful storms endanger the integrity of aquatic ecosystems and both wild and farmed animals. Over 80% of Zambian aquaculture producers face increased operating expenses of up to 20% due to drought, floods, cyclones, and threats of disease outbreaks due to limited species diversity and climate data. Ocean stratification and nutrient disruption are predicted to decrease 4-11% fish production by 2100, impacting tropical and coastal fisheries globally. The Intergovernmental Panel on Climate Change (IPCC) and WorldFish are promoting sustainable and gender-responsive policies to improve nutritional outcomes, equity, and ecological resilience through the integration of aquaculture with agriculture. This review emphasizes the need for integrated strategies to address species-level shifts, productivity declines, and adaptation equity in aquatic food systems through early warning systems, knowledge co-production, and community-led approaches. Current review concluded that integrated adaptation measures, climate-resilient aquaculture, ecosystem-based management, and the co-development of early-warning and knowledge systems are showing success in sustaining production and biodiversity. Global initiatives led by the IPCC and WorldFish are promoting sustainable, gender-responsive policies. Overall, evidence indicates that combining community-led action with cross-sectoral policy frameworks can reduce climate risks, safeguard aquatic biodiversity and strengthen the long-term resilience and equity of aquatic food systems.
