The proposed project assesses the risk of decreased marine ecosystem productivity as a turning point for the ecological, economic and social systems that are interconnected under the Humboldt Upwelling System (HUS). The system's climate-related productivity is highly variable and affects local livelihoods and global markets.

The project focuses on two marine systems; on the one hand the high seas pelagic system that supplies the Peruvian industrial anchovy fishery with attention to its regional and global impacts through exports to international markets. On the other hand there are the coastal (Independence Bay and Sechura Bay) and insular (Galapagos) systems where artisanal fisheries, aquaculture and ecotourism are key maritime activities for livelihood provision.

With a consortium of biogeochemists, fisheries ecologists, ocean and ecaosystem modellers, economists, social scientists and local communities from both Germany and Peru, we will work to understand the relationships between ecological, social and economic dynamics in the HUS.

Overview Work Packages

Humboldt-Tipping is performed in eight work packages (WPs) each of which has two to four Tasks. Activities within various WPs are highly interlinked. The system is separated into three Case Studies (pelagic, off-shore system, coastal bays and islands) based on differences in living marine resources and socioeconomics such as ecotourism, commercial and artisanal fisheries and aquaculture.
