Harmful algal blooms (HABs) occur in all 50 U.S. states and many produce toxins that cause illness or death in humans and commercially important species.
Harmful algal blooms (HABs) occur in all 50 U.S. states and many produce toxins that cause illness or death in humans and commercially important species. However, attempts to place a more exact dollar value on the full range of these impacts often vary widely in their methods and level of detail, which hinders understanding of the scale of their socio-economic effects.
In order to improve and harmonize estimates of HABs impacts nationwide, the National Oceanic and Atmospheric Administration (NOAA) National Center for Coastal Ocean Science (NCCOS) and the U.S. National Office for Harmful Algal Blooms at the Woods Hole Oceanographic Institution (WHOI) convened a workshop led by WHOI Oceanographer Emeritus Porter Hoagland and NCCOS Monitoring and Event Response (MERHAB) Program Manager Marc Suddleson. Participants focused on approaches to better assess the socio-economic effects of harmful algal blooms in the marine and freshwater (primarily Great Lakes) ecosystems of the United States. The workshop proceedings report describes the group’s objectives, and presents recommendations developed by 40 participants, mostly economists and social scientists from a range of universities, agencies, and U.S. regions. Their recommendations fall under two broad categories: those intended to help establish a socio-economic assessment framework, and those to help create a national agenda for HABs research.
“This has been a goal of the research and response communities for a long time, but coming up with a robust national estimate has been difficult, for a number of reasons, mainly related to the diversity of algal species and the wide variety of ways they can affect how humans use the oceans and freshwater bodies,” said Hoagland. “This gives us a strong base on which to build the insight that will vastly improve our estimates.”
