Who helps whom? The role of marine forests on the mitigation and adaptation to climate change - Livestream

The reduction of greenhouse gas emissions is essential to slow down the velocity of climate change. Likewise, the complementary implementation of other mitigation and adaptation strategies is equally important to increase environmental, social, and economic resilience. In the ocean, one strategy is to focus conservation and management actions on foundation species of marine macrophytes, such as seagrass meadows and kelp forests. First, the capacity of these systems to sequester carbon in the sediments (blue carbon) makes them carbon sinks at global scales. Second, the capacity of these systems to increase local mean pH by removing CO2 from seawater through net photosynthetic activity makes them important habitats to consider as ocean acidification (OA) refugia. However, while their carbon sink capacity is widely recognized, the capacity of marine macrophytes to effectively buffer OA is still an open question. In this talk, I will show the latter research I have developed on this topic in seagrass ecosystems and will give a glance at current and future work on kelp forests.
