Coastal Ecosystem-Based Management
Research Guide
What is Coastal Ecosystem-Based Management?
Coastal Ecosystem-Based Management (EBM) integrates ecological, social, and economic factors to sustain coastal ecosystems while balancing human uses like fisheries and aquaculture under climate pressures.
EBM emphasizes spatial mapping of human impacts, stakeholder engagement, and adaptive strategies for coastal resilience (Halpern et al., 2008, 6293 citations). Studies quantify cumulative effects on estuaries and seas, highlighting depletion and recovery potential (Lotze et al., 2006, 3250 citations). Over 10 key papers since 2006 address marine spatial planning and integrated assessments.
Why It Matters
EBM frameworks guide policy for coastal resilience against overfishing, pollution, and climate change, as mapped globally by Halpern et al. (2008) showing 41% of oceans under strong human impact. Lotze et al. (2006) demonstrate 70% biomass loss in estuaries, informing restoration priorities. Levin et al. (2009) provide quantitative tools for U.S. regional management decisions, while Ehler and Douvere (2009) outline steps for marine spatial planning adopted in Europe and Australia.
Key Research Challenges
Quantifying Cumulative Impacts
Mapping overlapping human activities like fishing and pollution requires multiscale spatial data synthesis (Halpern et al., 2008). Temporal changes complicate predictions, with impacts intensifying 14% from 2003-2013 (Halpern et al., 2015). Models struggle with data gaps in developing regions.
Stakeholder Engagement Barriers
Integrating diverse stakeholders in planning faces conflicts over resource access (Pomeroy and Douvere, 2008). Participation declines without clear benefits, limiting adaptive strategies. Halpern et al. (2019) note uneven global progress.
Modeling Stressor Interactions
Synergistic effects of multiple stressors like warming and acidification defy simple predictions (Piggott et al., 2015). Ecosystem models like Atlantis reveal nonlinear responses but demand high computational resources (Fulton et al., 2011).
