Climate risk maps for aquaculture and the occurrence of Harmful Algal Blooms as a significant threat in the Chilean Patagonia

In 2020, the Chilean Ministry of Environment introduced the “Climate Risk Atlas”, a centralized platform featuring maps related to climate risks in various sectors. The Interdisciplinary Center for Aquaculture Research, INCAR, played a key role in producing risk maps for aquaculture in collaboration with representatives from different institutions. Dr. Doris Soto, the center’s Principal Investigator, led the effort to address threats like harmful algal blooms (HABs) that are expected to increase in frequency and intensity due to reduced precipitation, especially when considering the forecasts of a possible dry summer in 2023-24 due to the presence of El Niño. Thus, the risk maps provide a comparative view of the risk and its components. 

Accompanying the maps is a report that suggests measures to mitigate comparative risks at the neighborhood and municipal levels. Recommendations include enhancing oceanographic monitoring and considering production reduction in high-risk areas. The report highlights the importance of establishing protected marine areas in strategic zones to effectively manage risks and capitalize on opportunities. 

The risk maps were generated with information available until 2020 but are subject to be updated and improved as better oceanographic, biological, and productive information becomes available at the ecosystem level.
