Poleward bound: adapting to climate-driven species redistribution
One of the most pronounced effects of climate change on the worldâs oceans is the (generally) poleward movement of species and fishery stocks in response to increasing water temperatures. In some regions, such redistributions are already causing dramatic shifts in marine socioecological systems, profoundly altering ecosystem structure and function, challenging domestic and international fisheries, and impacting on human communities. Such effects are expected to become increasingly widespread as waters continue to warm and species ranges continue to shift. Actions taken over the coming decade (2021â2030) can help us adapt to species redistributions and minimise negative impacts on ecosystems and human communities, achieving a more sustainable future in the face of ecosystem change. We describe key drivers related to climate-driven species redistributions that are likely to have a high impact and influence on whether a sustainable future is achievable by 2030. We posit two different futuresâa âbusiness as usualâ future and a technically achievable and more sustainable future, aligned with the Sustainable Development Goals. We then identify concrete actions that provide a pathway towards the more sustainable 2030 and that acknowledge and include Indigenous perspectives. Achieving this sustainable future will depend on improved monitoring and detection, and on adaptive, cooperative management to proactively respond to the challenge of species redistribution. We synthesise examples of such actions as the basis of a strategic approach to tackle this global-scale challenge for the benefit of humanity and ecosystems

An indicator framework to help maximise potential benefits for ecosystem services and biodiversity from ecological focus areas

However, there are concerns that they will provide little or no additional ecological benefit (enhanced biodiversity and ecosystem services) as those that are declared may already exist and/or any new areas will be implemented on the basis of farm management burdens rather than ecological criteria, such as those which are the easiest or least costly to implement. To implement ecological focus areas to achieve greater benefits requires taking account of numerous spatial and management parameters, scientific understanding of ecosystem services, and the needs and behaviour individual and communities of species. Such an approach is not readily practical or feasible for many farm and land managers. This paper describes the development of an indicator framework which aims to distil this complex scientific information to aid decision making with regard to the implementation of ecological focus areas to enhance and increase benefits for ecosystem services and biodiversity. It involved collating scientific evidence from over 350 papers, reports and guides and then structuring this evidence to form the indicator framework. 230 impacts were identified for 20 land uses and landscape features, and these are characterised using 138 parameters and attributes, containing 708 descriptive classes. The framework aims to help land managers identify the potential benefits and burdens of different options for the specific spatial and management context of their farm, and thus select those with greatest benefits and least burden for their circumstances. Ecological focus areas are part of the first evolution of greening measures, so there is scope to improve them to make their implementation more ecological and more focused. Tools, such as the indicator framework presented herein, have the potential to support this process by educating and raising awareness of potential impacts, facilitating the transfer of scientific knowledge, and resulting in a more ecological aware industry.Peer reviewedFinal Published versio
