“…Regime shifts have been reported for many marine ecosystems and in different contexts (Yletyinen et al 2016; Vasilakopoulos et al 2017; Nayak and Armitage 2018). In the systems adjacent to our study area, the Central Baltic Sea (Fig.…”

The occurrence of regime shifts in marine ecosystems has important implications for environmental legislation that requires setting reference levels and targets of quantitative restoration outcomes. The Baltic Sea ecosystem has undergone large changes in the 20th century related to anthropogenic pressures and climate variability, which have caused ecosystem reorganization. Here, we compiled historical information and identified relationships in our dataset using multivariate statistics and modeling across 31 biotic and abiotic variables from 1925 to 2005 in the Central Baltic Sea. We identified a series of ecosystem regime shifts in the 1930s, 1970s, and at the end of the 1980s/beginning of the 1990s. In the long term, the Central Baltic Sea showed a regime shift from a benthic to pelagic‐dominated state. Historically, benthic components played a significant role in trophic transfer, while in the more recent productive system pelagic–benthic coupling was weak and pelagic components dominated. Our analysis shows that for the entire time period, productivity, climate, and hydrography mainly affected the functioning of the food web, whereas fishing became important more recently. Eutrophication had far‐reaching direct and indirect impacts from a long‐term perspective and changed not only the trophic state of the system but also affected higher trophic levels. Our study also suggests a switch in regulatory drivers from salinity to oxygen. The “reference ecosystem” identified in our analysis may guide the establishment of an ecosystem state baseline and threshold values for ecosystem state indicators of the Central Baltic Sea.

“…Nurturing diversity in changing social-ecological systems can increase creativity and adaptive capacity, as well as setting the system for reorganization and renewal (Folke, 2016, Nayak andArmitage, 2018). Second, the adaptive co-management approach is widely used in natural resource management, including SSF in both developed and developing regions (Fidelman et al, 2017, Dale and.…”

“…These may include shared action and decision making where local communities engage with both/either volunteer and/or professional scientists (Charles et al 2020). There are few simple governance "solutions" to coastal socialecological regime shifts (WebPanel 1) due to the challenges of boundary, scale, and knowledge mismatches (Nayak and Armitage 2018). There exists a diverse range of legal protections and mechanisms (eg conservation easements, protection zones) that vary greatly across jurisdictions, and even within some jurisdictions; for instance, strategies to mitigate Sargassum blooms require a regional approach, yet manifest in different enforcement tools, incentive systems, and levels of governing capacity within individual Caribbean nations (Table 1).…”

A ccounting for nearly one-half of the world's ice-free coastline, sandy beaches support various human uses, especially recreation and tourism -both of which are expanding globally as a result of increased leisure time (McLachlan and Defeo 2018). The economies of many coastal states are dependent on this beach recreation-tourism link (McLachlan et al. 2013). With more than one billion visitors annually, tourism is a major industry, and even when other ecosystems are the focus (eg coral reefs), beaches are central to all coastal recreation experiences. Moreover, the global human population, currently approaching 8 billion, is increasingly concentrated in coastal areas, generating inevitable pressures on beaches despite inequities of access. Indeed, nowhere is a beach free from the human footprint, such that the interaction between their ecology and human activity cannot be ignored. This emphasizes the "triple whammy" affecting coastlines (Elliott et al. 2019;Fanini et al. 2020): increased urbanization and industrialization, increased use of physical and biological resources, and reduced resilience and resistance to climate change and other exogenous natural and anthropogenic pressures. Therefore, maintaining the ecosystem functions of the world's sandy shores in the face of increasing human recreational and aesthetic demands requires adoption of a more holistic social-ecological system (SES) perspective (see WebPanel 1 for definitions of selected specialist terms).Sandy beaches are the dominant land-sea interface worldwide and are closely coupled to adjacent surf zones and foredunes (Figure 1). These three systems form the core of the "littoral active zone" (LAZ), the section of the coast characterized by wind-and wave-driven sand transport (McLachlan and Defeo 2018) that provides important ecosystem services, including (1) recreation; (2) food; (3) wave dissipation and associated buffering against storms and sea-level rise (SLR); (4) assimilation of organic materials and pollutants; (5) maintenance of biodiversity, as well as nursery and nesting sites for various taxa, such as fish, sea turtles, shorebirds, and marine mammals; (6) water storage in dune aquifers and groundwater discharge; and (7) water filtration and nutrient mineralization and recycling (Defeo et al. 2009;Barbier et al. 2011). These ecosystem services are increasingly impacted by perturbations Sandy beach social-ecological systems at risk: regime shifts, collapses, and governance challenges
