正文(英文) | Two studies published in a special issue of the journal Science Advances this week (27 November 2019) highlight the fragility of the Antarctic and its ecosystems in the lead up to the UNFCCC COP25 meeting in Madrid next week. The first study, involving scientists from British Antarctic Survey (BAS), explores the integration of climate change considerations in the global network of Marine Protected Areas, and how this can contribute to ensuring a sustainable ocean future. ![]() Little is known about how well MPAs account for climate impacts, or how climate adaptation can be improved in the global MPA network. A key finding shows that the proportion of marine protected areas that account for climate change cannot be accurately measured, since there is no repository that holds this information. Developing a database to track climate adaptation plans in MPAs is one of eight recommendations that the researchers present. They also recommend the development of new dynamic management tools to allow a more rapid response to climate impacts.
Another crucial component of climate-smart conservation and management is that it is centred around building capacity in regions with limited resources, and around inclusiveness, bringing stakeholders fully into the discussion and the decision-making process. Dr Susie Grant, a marine biogeographer at BAS says:
The second study also published in the journal Science Advances, is a review by BAS scientists. It discusses how Antarctica’s unique and delicate ecosystems face the dual problems of climate change and direct human impacts, in particular the accidental introduction of non-native or ‘alien’ species.’ The scientists analysed existing literature on the environmental challenges facing the continent and the Southern Ocean. The study reaffirms the importance of all parties of the Antarctic Treaty continuing their commitment to governance of the region, as it still contains the best mechanisms to protect and preserve the environment. The scientists praise the establishment of the first genetic database of Antarctic species in New Zealand and recommend this is extended to create a comprehensive genetic archive for future generations to use. The Southern Ocean has some of the highest levels of biodiversity in the globe, second only to that of coral reefs. In contrast, Antarctica’s terrestrial ecosystems include some of the least diverse on the planet. However, both have long been effectively cut off from the rest of the world, leading to evolutionary radiation and adaptation to it unique environments. Lead author Professor Peter Convey from BAS says:
