Marine ecosystem-based management: challenges remain, yet solutions exist, and progress is occurring

npj Ocean Sustainability, Год журнала: 2024, Номер 3(1)

Опубликована: Фев. 12, 2024

Abstract Marine ecosystem-based management (EBM) is recognized as the best practice for managing multiple ocean-use sectors, explicitly addressing tradeoffs among them. However, implementation perceived challenging and often slow. A poll of over 150 international EBM experts revealed progress, challenges, solutions in worldwide. Subsequent follow-up discussions with 40 these identified remaining impediments to further EBM: governance; stakeholder engagement; support; uncertainty about understanding EBM; technology data; communication marketing. portrayed too complex or be fully implemented, but we report that identifiable achievable exist (e.g., political will, persistence, capacity building, changing incentives, strategic marketing EBM), most challenges some can solve many simultaneously. Furthermore, are advancing key components by practitioners who may not necessarily realize they doing so under different paradigms. These findings indicate substantial progress on EBM, more than previously reported.

Understanding the global impact of offshore wind farms (OWF) on biodiversity and ecosystem services (ES) is crucial in developing sustainable energy transition pathways. This study takes a holistic approach, coupling semi-systematic review with novel analytical methodology, to consider consequences construction & operation OWF deployment ES. 314 pieces evidence taken from 132 peer-reviewed studies provide basis determine ecological ES impacts. The process showed that impacts were predominantly negative across subject groups (52%), compared positive (8%) several species fish (e.g. brill, cod, dab, plaice) some birds common guillemot, northern fulmar, redhead) showing strongly trends.

The importance of essential fatty acids and their ratios in aquafeeds to enhance salmonid production, welfare, and human health

Frontiers in Animal Science, Год журнала: 2023, Номер 4

Long chain polyunsaturated fatty acids (LC-PUFA), namely those from omega-3 (n-3) and omega-6 (n-6) families, are paramount for both fish human nutrition. Some of these biomolecules cannot be synthesized de novo must acquired through the diet, being termed dietary essential (EFA). Fish requirements EFA have traditionally been met incorporation oil (FO) in formulation aquafeeds. However, with limited supply FO aquaculture industry is searching additional sustainable sources LC-PUFA. This has significantly shifted type ingredients used aquafeed formulation, vegetable oils (VO) deficient long-chain omega-3, often resulting imbalanced levels ratios acid classes. Such imbalances can negatively affect performance welfare, as well health promoting LC-PUFA present fillets. Given relevance that salmonid plays global production (principally Atlantic salmon, Salmo salar ), its growing role a source humans, review summarizes scientific knowledge available to date on by salmonids humans. We discuss implications using formulations upon subsequent consequences nutrition, along current efforts replace alternative such algal (AO) safeguard high-quality products consumption.

Meta-analysis indicates better climate adaptation and mitigation performance of hybrid engineering-natural coastal defence measures

Nature Communications, Год журнала: 2024, Номер 15(1)

Опубликована: Апрель 9, 2024

Abstract Traditional approaches to coastal defence often struggle reduce the risks of accelerated climate change. Incorporating nature-based components into defences may enhance adaptation change with added benefits, but we need compare their performance against conventional hard measures. We conduct a meta-analysis that compares performances hard, hybrid, soft and natural measures for across different functions risk reduction, mitigation, cost-effectiveness. Hybrid offer higher reduction mitigation benefits than unvegetated systems, while performing on par Soft hybrid are more cost-effective measures, provide highest hazard among all All have positive economic return over 20-year period. Mindful context, our results strong an evidence-base integrating upscaling in lower areas.

Rapid and drastic anthropogenic impacts are affecting global biogeochemical processes driving biodiversity loss across Earth's ecosystems. In aquatic ecosystems, species distributions shifting, abundances of many have declined dramatically, threatened with extinction. addition to diversity, the ecosystem functions, services on which humans depend also being heavily impacted. Addressing these challenges not only requires direct action mitigate environmental but innovative approaches identify, quantify treat their effects in environment. Mesocosms valuable tools for achieving goals as they provide controlled environments evaluating stressors testing novel mitigation measures at multiple levels biological organisation. Here, we summarise discussions from a survey marine freshwater researchers who use mesocosm systems synthesise opportunities limitations advancing solutions grand ecological While most research utilising ecology has focused quantifying threats, there is largely unexplored potential using them test solutions. To overcome spatio‐temporal constraints, scale up size time‐scales studies, or alternatively, outcomes habitat‐scale restoration smaller scale. Enhancing connectivity future studies can help limitation isolation an important aspect recovery. Conducting ‘metacosm' studies: coordinated, distributed experiments spanning wide climatic gradients more regression‐based experimental designs tackle challenge context dependent results.
