Abstract. Climate change has multiple effects on Baltic Sea species, communities and ecosystem functioning through changes in physical biogeochemical environmental characteristics of the sea. Associated indirect secondary species interactions, trophic dynamics function are expected to be significant. We review studies investigating species-, population- ecosystem-level abiotic factors that may due global climate change, such as temperature, salinity, oxygen, pH, nutrient levels, more food web processes, primarily based peer-reviewed literature published since 2010.

Journal of Environmental Management, Год журнала: 2024, Номер 357, С. 120685 - 120685

Опубликована: Март 28, 2024

Fisheries social-ecological systems (SES) in the North Sea region confront multifaceted challenges stemming from environmental changes, offshore wind farm expansion, and marine protected area establishment. In this paper, we demonstrate utility of a Bayesian Belief Network (BN) approach comprehensively capturing assessing intricate spatial dynamics within German plaice-related fisheries SES. The BN integrates ecological, economic, socio-cultural factors to generate high-resolution maps profitability adaptive capacity potential (ACP) as prospective management targets. Our analysis future scenarios, delineating changes constraints, economics, aspects, identifies that will exert significant influence on SES near future. These include loss fishing grounds due installation farms areas, well reduced plaice landings climate change. identified ACP hotspots hold guide development localized strategies sustainable planning efforts by highlighting consequences decisions. findings emphasize need consider detailed (MSP) illustrate how information may assist decision-makers practitioners prioritization. We, therefore, propose adopting concept broader integrated approaches foster inherently dynamic rapidly evolving environment.

Опубликована: Март 21, 2022

Abstract The Northern Humboldt Current System sustains one of the most productive fisheries in world. However, climate change is anticipated to negatively affect fish production this region over next few decades, and detailed analyses for many fishery resources are unavailable. We implemented a trait-based Climate Vulnerability Assessment based on expert elicitation estimate relative vulnerability 28 (benthic, demersal, pelagic) impacts by 2055; ten exposure factors (e.g., temperature, salinity, pH, chlorophyll) 13 sensitivity attributes (biological population-level traits) were used. Nearly 36% species assessed had “high” or “very high” vulnerability. Benthic ranked vulnerable (gastropod bivalve species). pelagic group was second vulnerable; Pacific chub mackerel yellowfin tuna amongst species. demersal relatively lowest This study allowed identification resources, research monitoring priorities, key which driving that Our findings can help managers incorporate into harvest level allocation decisions, assist stakeholders plan adapt changing future.

Despite progress in understanding and predicting climate change impacts possible responses for US marine fisheries, use of climate-related information federal fishery management decisions remains limited. One barrier to linking knowledge action is that individual bodies' efforts tend be isolated, with few opportunities coordinate or communicate about successes shared challenges. To promote cross-regional learning, we distill eight best practices from emerging climate-focused efforts, drawn a collaborative workshop, literature, authors' experiences. We conceptualize these as interrelated—and incomplete—pieces knowledge-to-action "puzzle" could adopted based on regional context. practice, mapping out processes structure identify "on-ramps" (3.1), represents foundational centerpiece enables other practices. Three apply primarily internal processes: frame initiatives within existing mandates (3.2); strategically incorporate qualitative deal uncertainty (3.3); pilot healthy lower-risk stocks (3.4). Another set pertains include broader stakeholders: engage stakeholders early often (3.5), emphasize local priorities (3.6), employ structured keep track (3.7), leverage research build trust overcome capacity constraints (3.8). highlight demonstrate how were implemented, discuss continued challenges, where expanded support climate-ready fisheries.

Adapting to the anthropogenic environmental change while transitioning a more sustainable and productive natural resource management places unprecedented demands on production. Meeting this complex challenge without unwarranted degradation or loss of livelihoods requires understanding managing resilience properties that produce resources. However, insufficient attention has been paid in research governance capacity producers adapt achieve outcomes at property-level, potentially leading unintended social outcomes. We used large detailed survey data farmers, foresters, growers New Zealand identify factors correlate with property-level are desirable from perspective production: strong performance, good financial situation, high well-being. The results detail how these diverse individual traits outlooks, agroecosystem characteristics, economic resources, interactions. different drive outcomes, factor is positively correlated one outcome may negatively another. only all three was goal have performance future, which reflect optimism as determinant. Thus, difficulty achieving across dimensions arise conflicting effects environmental, economic, well-being In conclusion, our indicate must carefully consider interdependencies between financial, support ability meet society's demands.

Climate change continues to alter the productivity of commercially and culturally important fisheries with major consequences for food security coastal economies. We provide first, multi-model projections changes in distribution 18 key fish stocks across seven European regional seas spanning Mediterranean Arctic, using 11 state-of-the-art bio-ecological models. Our indicate species- region-specific abundance distributions these by mid- late 21st century. The varied responses are caused differences species' physiology, web dynamics, physical habitat characteristics. Important drivers include not only warming Europe's (from 1°C 3°C RCP 4.5, 2°C 4°C 8.5 2100) primary but also oxygen-limited growth, pH, benthic dissolved organic carbon. Warming altered levels secondary production projected lead declines some (Norwegian Barents Sea herring) increases others (Bay Biscay anchovy). While temperate cold-water decline markedly regions (e.g., North Sea, Western Mediterranean), immigration species from south and/or increase warm-water may offer new opportunities fisheries. Species-level will likely have ecosystem-level that yet be fully assessed, sub-areas more pronounced due local processes captured projections. Projections consistent despite model structures, results our analysis align other modelling exercises while delving into details often overlooked at or spatial level. This represents a novel approach projecting impacts climate on fisheries, which should considered future efforts support climate-ready management strategies marine stocks.

Frontiers in Marine Science, Год журнала: 2025, Номер 12

Опубликована: Апрель 22, 2025

Europe’s marine and coastal ecosystems provide essential ecosystem services, however, their ability to support climate adaptation mitigation is increasingly threatened by anthropogenic pressures. This systematic literature review identifies evaluates integrated approaches that align conservation with adaptation, revealing untapped potential in leveraging synergies across governance, planning, management, sectoral integration. Despite extensive research both fields, interlinkages remain underexplored, implementation often fragmented early development stages. Our findings identify major nexus approaches, particularly ecosystem-based strategies, which, when effectively applied, strengthen the resilience of social-ecological systems. Central measures include climate-smart protected areas, restoration (e.g., for wetlands, reefs, dunes, seagrasses), pollution control, hybrid protection solutions. However, success hinges on cross-sectoral coordination, robust adaptive effective stakeholder engagement, long-term monitoring, financial sustainability. A critical gap integrating reflects not only a shortfall but also barriers policy practice. Addressing trade-offs between crucial maximizing while avoiding unintended socio-economic consequences. The study underscores need science-policy integration transformative governance frameworks implement strategies at scale. Strengthening regulatory coherence, into spatial expanding financing mechanisms are operationalizing these effectively. These insights pathways policymakers, researchers practitioners develop resilient, management face accelerating change.
