The UK and many areas of Europe have witnessed unprecedented flooding this winter. Severe long-term flooding of agricultural land can have disastrous impacts on ecosystem functioning as well as having severe consequences on the economic and social wellbeing of rural communities. The persistence and magnitude of floodwaters in parts of the UK (e.g. Somerset Levels) provide a unique opportunity to investigate the impacts of long-term floodwater inundation on soil health and ecosystem service delivery. The aim of this 'Urgency' project is to: (1) provide vital information on the negative effects of recent flood events on soil functioning, (2) identify potential tipping points in terms of inundation time, (3) quantify rates of ecosystem function recovery and any potentially irreversible effects, (4) identify potential future intervention measures to promote ecosystem recovery, (5) provide stakeholders (e.g. landowners, Defra, NFU, EA) with critical scientific information to be able to make informed decisions (i.e. to minimize immediate impacts such as production losses) and respond and adapt to potential future flood events.

今年冬天，英国和欧洲许多地区都发生了前所未有的洪水。农业用地长期遭受严重洪灾可能对生态系统的功能产生灾难性影响，并对农村社区的经济和社会福祉造成严重后果。英国部分地区（例如萨默塞特水平）洪水的持续性和规模为调查长期洪水淹没对土壤健康和生态系统服务提供的影响提供了独特的机会。这个“紧急”项目的目的是：（1）提供关于近期洪水事件对土壤功能的负面影响的重要信息，（2）确定淹没时间方面的潜在临界点，（3）量化生态系统功能恢复的速度和任何潜在的不可逆转的影响，（4）确定未来潜在的干预措施，以促进生态系统恢复，（5）为利益相关者（如土地所有者、Defra、NFU、EA）提供关键的科学信息，以便能够做出明智的决策（即最大限度地减少生产损失等直接影响），并应对和适应未来可能发生的洪水事件。
