EFFECTS OF CLIMATE CHANGE AND LAND USE ON LARGE LAKE FISHERIES AROUND THE WORLD
Understanding effects of climate and land use changes on the production of large lake fisheries is critical because they provide for livelihoods, nutrition, food security, and recreation in different parts of the world. In this study, we used a Bayesian network modeling approach to investigate effects of climate and land use changes on fisheries production across 30 large lakes in 5 continents. The analytical framework was to model effects of climate and land use changes in the watershed on primary production, water level, and water temperature in the lake, and consequential effects on observed fisheries harvests in the period of 1970–2014. In addition, these 30 lakes were categorized by depth and food and water security levels, as these two factors influence the extent to which climate or land use changes affect fisheries production. Results from this study will have implications for identifying lakes that are most vulnerable to climate and land use changes, which is needed information for managers (e.g., Food and Agriculture Organization of the United Nations) who have been challenged to ensure sustainable fisheries for food security and human welfare.
