ABSTRACT

Globally, anthropogenic actions of land use change and intensification and deliberate or unintentional species invasions have adversely affected lakes, resulting in widespread loss of benefits to society. In recognition of these impacts, restoration efforts have increased in recent years. Restoration is a challenging and expensive process, however, and success rates are variable and often unpredictable. Here, we demonstrate that early actions to prevent degradation of lakes currently in good ecological condition are preferable to attempting to restore lakes that have been allowed to degrade, to allow continuity of ecosystem services. We compare case studies for 3 lakes that use preventative approaches to mitigate the effects of anthropogenic pressures. These initiatives aim to protect or enhance long-term societal benefits through building resilient ecosystems and maintaining ecological integrity. They differ from restoration projects, where lakes are often in an advanced state of degradation resilient to modest restoration efforts. We identify the need to mainstream preventative lake management including building a robust evidence base to support initiatives aimed at reversing the early stages of changes in ecological state.

湖泊管理:预防胜于治疗?

摘要

在全球范围内,土地利用变化和集约化的人为行为以及蓄意或无意的物种入侵对湖泊产生了不利影响,导致社会利益普遍丧失。认识到这些影响,近年来恢复工作有所增加。然而,修复是一个具有挑战性和昂贵的过程,成功率是可变的,而且往往是不可预测的。在这里,我们证明了防止目前处于良好生态状况的湖泊退化的早期行动比试图恢复已经允许退化的湖泊更可取,以允许生态系统服务的连续性。我们比较了 3 个湖泊的案例研究,这些湖泊使用预防方法来减轻人为压力的影响。这些举措旨在通过建立有弹性的生态系统和维护生态完整性来保护或增强长期社会效益。它们与恢复项目不同,在这些项目中,湖泊通常处于退化的高级状态,可以抵御适度的恢复工作。我们确定了将预防性湖泊管理纳入主流的必要性,包括建立强有力的证据基础,以支持旨在扭转生态状态变化早期阶段的举措。
