The tenth episode of the Ocean Governance Podcast focuses on marine protected areas (MPAs). While being a well-established and much-discussed instrument for protection of the marine environment, the three articles discussed in this episode show that interesting perspectives can still be added to the discourse on MPAs.
Our first article looks at the blending of rationales in designating and managing many large-scale MPAs in areas with a strong military legacy and sometimes also a remaining military presence. Although not drawing strong general conclusions about the effects of military legacies or military activities in MPAs, the author opens up an interesting discussion on the multiple interests and legacies that can affect marine areas and shape the conditions for their conservation and management.
The second article, with a message directed to the ongoing negotiations on protection of biodiversity in areas beyond national jurisdiction, calls for the elaboration of new dynamic management tools, including mobile MPAs to be employed in high seas areas. Although mobile MPAs entail practical and policy challenges, the article provides strong arguments both for the utility and need of such an instrument and points to factors that could facilitate the practical operation of such MPAs. Not least rapid technological development in areas such as animal tracking, vessel monitoring and communication make such measures practically feasible.
The third article constructively challenges the oft-repeated idea that MPAs are a good way of strengthening the resilience of marine ecosystems in the face of climate change. Noting the scarcity of empirical support for ecosystems within MPAs being less negatively affected by climate change related pressures such as rising water temperatures or severe storms, the authors point to factors that may actually make protected areas (seem) more rather than less vulnerable. This, however, does not mean that MPAs cannot be useful in countering the effects of climate change although their effectiveness may be more limited than often thought, and also require integrating climate change factors in the designation of protected areas.
