Ecosystem Services | Year: 2017

In late 2005 the lower stretches of the Olifants river in South Africa, flowing through the Kruger National Park before entering Mocambique, dried up for 78. days, curtailing critical ecosystem services. Our retrospective case study attributes this to failure of effective cross-scale collaboration and co-constructed action. We detail how a more effective response was mounted after the governance crisis had first deepened, which, along with more recent broader but related societal responses, has maintained these water-related ecosystem services.The narrative describes part crisis response, part chance emergence, and along the way building of trust. Persistent staff capacity across agencies, whose members developed a sufficiently overlapping vision, was deemed crucial. The widening of linkages across scales and levels was a key feature, though attention is drawn to other important factors such as power dynamics. The difficulties encountered gave birth to new hope, with full recognition that such messy and dynamic social-ecological systems need to be navigated as best possible using complexity-friendly adaptive approaches, containing elements (including important cross-scale ones) that came together in this case. This case narrative is believed to contain generic lessons for ecosystem service governance. © 2017 Elsevier B.V.

Aquatic ecosystems are connected over large spatial scales, have varied drivers, strong and often conflicting societal interests and interacting management processes. Many of the world's protected areas (100,000, ~12% of land) include freshwater ecosystems, some specifically declared for freshwater protection, but often supplied by rivers outside their protected boundaries. Such complex socio-ecological systems have considerable challenges. We report on Strategic Adaptive Management (SAM), a management framework that should be implemented, irrespective of resourcing, in protected areas of any river system, ranging from heavily managed or regulated through to pristine rivers. We briefly outline the four stages of the SAM process for aquatic protected areas and present three case studies from South Africa and Australia in different stages of SAM implementation. Progress is incremental, reflecting gaps, problems, and socio-ecological dynamism. Real-world implementation usually means such management is passive although experimentation with environmental flows remains possible. While maturity in SAM is incremental over years or decades, it can and should be applied even if environmental problems are urgent and contentious. The stages of SAM should produce an agreed vision and/or mission among stakeholders, with an appropriate hierarchy of objectives that determines indicators to be measured, allowing ongoing reflection, learning and adaptation. There is no panacea for achieving aquatic conservation, but Strategic Adaptive Management offers hope with its interlinked processes for navigating complexity and learning. SAM in freshwater conservation is progressing because of the imperative for sustainability, history of interaction between scientists and managers and the need for transdisciplinary governance of rivers. © 2010.
