Abstract

Chile is highly vulnerable to climate change since it has coastline areas of low height, arid, semi-arid and forest areas, susceptibility to natural disasters, areas prone to droughts and desertification, urban areas with atmospheric pollution issues and mountain ecosystems. Ocean acidification, variations in the sea temperature and level, as well as the increase in the frequency and intensity of extreme events, such as surges, rainfall, El Niño-Southern Oscillation (ENSO), have a direct impact on the ocean’s primary and secondary production, on the biological cycles and their seasonality, on the distribution of fishing resources, and on the supporting infrastructure for fisheries and aquaculture activities, which ultimately affect the benefits of the communities dedicated to the extraction of fishing resources and small-scale aquaculture activities.
