Funding sustained, effective management of marine protected areas is one of ocean conservation's most stubborn problems. Now, a new study from researchers at UC San Diego's Scripps Institution of Oceanography links fish recovery from well-managed marine protected areas to increased revenue from scuba diving tourism. The study, published Jan. 21 in the journal Ecological Economics, then translates those findings into a framework that creates financial projections to help managers or investors evaluate the potential economic benefits of marine conservation.
