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

淡水是一种重要的资源，仍然受到广泛的人类活动和环境变化的威胁。该奖项支持的研讨会是在淡水势在必行25周年之际举办的，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《淡水当务之急》是一项合作努力，旨在对淡水生态系统进行预测性了解，从而在不断变化的环境中改进管理和减缓做法。 在淡水势在必行25周年之际举行的研讨会上，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。通过多种活动，研讨会与会者将确定淡水科学的重大挑战，并制定前瞻性的研究议程。讲习班的目的是确定淡水生态系统研究和管理的主要挑战，综合现有的认识，努力填补关键的知识空白，并考虑尖端的分析方法和新出现的方法如何为短期和长期研究议程提供信息。 具体而言，讲习班的参与者将被问到：淡水势在必行的预测已经实现了吗？目前有哪些威胁和挑战没有预测到？新研究议程的组成部分是什么？ 提出这些问题的原因是淡水资源持续退化，而且在许多情况下正在加速退化，加上过去25年来开发的创新研究工具和方法激增，其中许多是意料之外的。 该项目将包括三项主要活动。首先，它将对科学界进行一次大挑战调查，以便广泛参与和提供投入。其次，它将在相关研究会议上主办一次特别会议，通过回顾性会谈和关于新兴工具和研究方向的前瞻性会谈相结合，让社区参与。最后，它将组织一次讲习班，综合各种重大挑战并解决主要问题。与会者将包括主要是早期职业科学家除了一些谁是原来的淡水势在必行的一部分。该讲习班将邀请具有淡水环境方面各种专门知识的科学家参加，并将采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，并为决策者提供指导。该研讨会由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支持。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值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.
