REWILDING AND RESTORATION OF INTERTIDAL SEDIMENT ECOSYSTEMS FOR CARBON SEQUESTRATION, CLIMATE ADAPTATION AND BIODIVERSITY SUPPORT

在欧洲海岸带内，由每次退潮时涌出的软沉积物组成的潮间带，沿着35000公里的潮汐海岸线形成了覆盖10000多平方公里的复杂海景。这些栖息地提供多种生态系统服务，通过促进碳中和、气候恢复和生物多样性支持，具有应对生物多样性-气候危机的巨大潜力。然而，这些海景继续支离破碎，受到威胁，导致它们提供的服务减少。重新野生是一种基于自然的解决方案，对于海景来说，这是一个新的概念，旨在扭转这种情况，并(再次)让自然来做这项工作，以确保未来欧洲海岸线的气候弹性、生物多样性支持和社会利益。在一个由来自11个欧洲国家的10名示威者和25个合作伙伴组成的网络中，包括8个拥有潮汐海岸的国家，以及英国、加拿大和美国，REWRITE将带来一个由自然和沿海环境、社会科学和人文专家组成的跨学科联盟，以应对当前关于潮间带海景重新野生的生态和社会挑战。扩大创新方法，重写将侧重于气候-生物多样性社会关系，以实现4个具体目标：-确定在气候变化背景下重新形成潮间带沉积物海景的环境、社会和文化驱动因素和屏障参数；-大力动员利益攸关方实现他们对这些海景自然功能的欣赏的阶段性变化，并将他们的利益纳入未来欧洲海岸线的共同设计情景中；-估计和提高潮间带海景从当地到欧洲水平的轨迹，遵循重新野生(被动)、恢复(主动)、“一切照旧”或“什么都不做”的选择；-建立成功重新开垦的工具和方法，确保气候中立和有弹性的欧洲海岸线有较高的生态和社会效益/低成本比率

Within European coastal zones, intertidal areas consisting of soft sediment emerging during each low tide, form complex seascapes covering more than 10 000 km2 along the 35 000 km of the tidal coastline. These habitats provide multiple ecosystem services with great potential to cope with the biodiversity-climate crisis by contributing to carbon neutrality, climate resilience and biodiversity support. Nevertheless, these seascapes continue to be fragmented and threatened, resulting in a decrease of their provision of services. Rewilding, a nature-based solution, is a new concept for seascapes to reverse this situation and to “let (again) Nature do the job” ensuring climate resilience, biodiversity support and societal benefit of the future European shoreline. Within a network of 10 demonstrators and 25 partners from 11 European states, including 8 with a tidal coast, plus the UK, Canada and the USA, REWRITE will bring an interdisciplinary consortium of natural and coastal environment and social sciences and humanities experts to address the current ecological and social challenges regarding intertidal seascape rewilding. Expanding innovative approaches, REWRITE will focus on the climate-biodiversity society nexus, to reach 4 specific objectives: -identify environmental, social and cultural drivers and barrier parameters to rewild intertidal sediment seascapes within the context of climate change; -strongly engage stakeholders to achieve a step-change in their appreciation of the natural function of these seascapes and integrate their interests within a co-design of scenario for future European shoreline; - estimate and upscale trajectories of intertidal seascapes from the local to the European level, following rewilding (passive), restoring (active), “business as usual” or “do nothing” options; -establish tools and methods for successful rewilding to ensure a high ecological and societal co-benefit/low-cost ratio for a climate-neutral and resilient European shoreline
