Global Harmful Algal Blooms

17-19 October 2019, Victoria, B.C. Canada


Over the last two decades, several reports have compiled what is known about the economic effects of harmful algal blooms. However, both the type and amount of available data are limited, and these reports largely have been compiled by marine scientists rather than economists. Most coastal states have neither conducted economic analyses of HABs nor collected data that can be used to generate reliable quantitative estimates of net economic impacts. 


This workshop will provide science-based progress towards achieving ocean Sustainable Development Goals. The output will be a guide on best practices for quantifying economic effects of HABs that focuses on establishing connections between HAB researchers and economists. A shorter version of the guide may be prepared for submission to a journal. The workshop also will (1) set priorities for the future, (2) develop partnerships among social scientists, economists and HAB researchers, and (3) hopefully, attract resources to the field.
