Revisiting the Freshwater Imperative: A workshop to synthesize and prioritize key challenges in freshwater science

淡水是一种关键资源，仍然受到广泛的人类活动和环境变化的威胁。这一奖项支持的研讨会是在淡水必要性25周年之际举行的，这是一项由关注淡水环境可持续管理的科学家制定的研究议程。最初的淡水需求是一项合作努力，目的是发展对淡水生态系统的预测性理解，从而在不断变化的环境中改进管理和缓解做法。在淡水命令25周年之际举办的这一讲习班期间，与会者将反思淡水科学家在过去几十年中取得的成就，错过了哪些研究机会，以及在应对环境危机方面吸取了哪些教训。通过多项活动，研讨会参与者将确定淡水科学领域的重大挑战，并制定前瞻性研究议程。讲习班的目的是确定淡水生态系统研究和管理面临的主要挑战，综合现有的认识，努力填补关键的知识空白，并审议前沿分析方法和新兴方法如何为短期和长期研究议程提供信息。具体而言，研讨会与会者将被问到：淡水需求的预测实现了吗？当前有哪些威胁和挑战没有预料到？新的研究议程有哪些组成部分？这些问题的动机是淡水资源的持续退化，在许多情况下加速退化，以及过去25年来开发的创新研究工具和方法的爆炸性增长，其中许多都是意想不到的。该项目将包括三项主要活动。首先，它将对科学界进行一次重大挑战调查，以允许广泛参与和投入。其次，它将在相关的研究会议上主办一次特别会议，通过回顾讲座和关于新兴工具和研究方向的前瞻性演讲相结合的方式，让社区参与进来。最后，它将组织一次研讨会，以综合重大挑战并解决主要问题。参与者将包括主要是职业生涯早期的科学家，以及一些最初参与淡水命令的人。讲习班将有与淡水环境有关的一系列专业知识的科学家参加，并将使用团队科学方法开发产品，向科学界通报尚未回答的关键问题，并为政策制定者提供指导。该研讨会得到了环境生物学部的生态系统科学计划和地球科学部的水文科学计划的支持。这一奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

Freshwater is a critical resource that remains threatened by a wide range of human activities and environmental change. The workshop supported by this award is predicated on the 25th anniversary of the Freshwater Imperative, a research agenda developed by scientists concerned about sustainable management of freshwater environments. The original Freshwater Imperative was a collaborative effort to develop to a predictive understanding of freshwater ecosystems that would translate to improved management and mitigation practices in changing environments. During this workshop held on the 25th anniversary of the Freshwater Imperative, participants will reflect on what freshwater scientists have accomplished over the past decades, what research opportunities have been missed, and what lessons have been learned about responding to environmental crises. Through multiple activities, workshop participants will identify grand challenges in freshwater science and craft a forward-looking research agenda. The workshop will aim to identify the key challenges for freshwater ecosystem research and management, to synthesize existing understanding in an effort to fill critical knowledge gaps, and to consider how cutting-edge analytical approaches and emerging methods can inform both short- and long-term research agendas. Specifically, the workshop participants will be asked: Have predictions of the Freshwater Imperative been realized? What current threats and challenges were not predicted? What are the components of a new research agenda? These questions are motivated by the continued, and in many cases, accelerating degradation of freshwater resources, combined with an explosion of innovative research tools and approaches developed over the past 25 years, many of which were unanticipated. The project will encompass three main activities. First, it will conduct a Grand Challenges survey of the scientific community to allow for broad participation and input. Second, it will host a special session at a relevant research conference to allow for community engagement through a combination of retrospective talks and prospective talks about emerging tools and research directions. Finally, it will organize a workshop to synthesize the Grand Challenges and address the primary questions. Participants will include predominantly early career scientists in addition to some who were part of the original Freshwater Imperative. The workshop will involve scientists with a range of expertise related to freshwater environments, and will use team science approaches to develop products that will inform the scientific community about critical unanswered questions, as well as provide guidance to policy makers. The workshop is supported by the Ecosystem Science program in the Division of Environmental Biology and the Hydrologic Sciences program in the Division of Earth Sciences.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
