Abstract
Ecosystems experiencing pressures are at risk of rapidly transitioning (‘tipping’) from one state to another. Identifying and managing these so-called tipping points continues to be a challenge in marine, freshwater, and terrestrial ecosystems, particularly when multiple potentially interacting drivers are present. Knowledge of tipping points, the mechanisms that cause them, and their implications for management practices are evolving, but often in isolation within specific ecological realms. Here we summarize current knowledge of tipping points in marine, freshwater, and terrestrial realms, and provide a multi-realm perspective of the challenges and opportunities for applying this knowledge to ecosystem management. We brought together conservation practitioners and global experts in marine, freshwater, and terrestrial tipping points and identified seven challenges that environmental policymakers and managers contend with including: 1) predictability, 2) spatiotemporal scales, 3) interactions, 4) reversibility, 5) socio-ecological context, 6) complexity and heterogeneity, and 7) selecting appropriate action. We highlight opportunities for cross-scalar and cross-realm knowledge production and provide recommendations for enabling management of tipping points. Although knowledge of tipping points is imperfect, we stress the need to continue working towards incorporating tipping points perspectives in environmental management across all realms.
期刊介绍:
Published since 1993, Environmental Reviews is a quarterly journal that presents authoritative literature reviews on a wide range of environmental science and associated environmental studies topics, with emphasis on the effects on and response of both natural and manmade ecosystems to anthropogenic stress. The authorship and scope are international, with critical literature reviews submitted and invited on such topics as sustainability, water supply management, climate change, harvesting impacts, acid rain, pesticide use, lake acidification, air and marine pollution, oil and gas development, biological control, food chain biomagnification, rehabilitation of polluted aquatic systems, erosion, forestry, bio-indicators of environmental stress, conservation of biodiversity, and many other environmental issues.
