Article Synopsis
- Food production of fed animals, like broiler chickens and salmon, significantly contributes to global environmental degradation, necessitating effective food policies for sustainability.* -
- The study highlights that farming broiler chickens impacts nine times more land area than salmon, though chickens produce 55 times the output, with a large concentration of environmental pressures in specific locations.* -
- Shared feed ingredients are a major contributor to environmental pressures in both sectors, indicating a crucial area for improvement in reducing ecological footprints and promoting sustainability through integrated food policies.*
Article Synopsis
- * The study analyzed disruptions in the seafood supply chain from January to May 2020, using a resilience framework to assess the varying impacts on different market segments and actors.
- * Key findings suggest that some groups have demonstrated resilience, while others are vulnerable, leading to recommendations for adaptive strategies and research to enhance future resilience in the seafood sector.
The US seafood sector is susceptible to shocks, both because of the seasonal nature of many of its domestic fisheries and its global position as a top importer and exporter of seafood. However, many data sets that could inform science and policy during an emerging event do not exist or are only released months or years later. Here, we synthesize multiple data sources from across the seafood supply chain, including unconventional real-time data sets, to show the relative initial responses and indicators of recovery during the COVID-19 pandemic.

- - Fisheries and aquaculture are vital for global food security, nutrition, and livelihoods, but the UN's Sustainable Development Goals treat marine and terrestrial food systems separately, making it essential to recognize their interconnections.
- - Countries reliant on fisheries face unique challenges related to climate change, which could worsen outcomes in both fisheries and agriculture, requiring strategies that consider the trade-offs between food production, biodiversity, and climate goals.
- - To address these challenges, particularly in nations with low adaptive capacity, effective governance, improved management, innovative food production methods, and equitable resource distribution are necessary for sustainable development.
Considering land-sea interactions and trade-offs for food and biodiversity.

Article Synopsis
- The human population is projected to reach 10 billion by 2050, increasing demand for animal protein and stressing natural resources, making sustainable food production crucial.
- Traditional approaches to agriculture and fisheries have often focused on individual sectors, ignoring the important connections between land and sea food systems that could lead to unexpected consequences.
- To enhance sustainability, it's essential to understand interactions across food systems and improve both production and consumption efficiency, while integrating research and policies that consider these complex land-sea relationships.
Rationale And Experimental Approach: Aggregate dredging is a growing source of anthropogenic disturbance in coastal UK waters and has the potential to impact marine systems through the smothering of benthic fauna with organically loaded screening discards. This study investigates the tolerance of the blue mussel, Mytilus edulis to such episodic smothering events using a multi-factorial design, including organic matter concentration, temperature, sediment fraction size and duration of burial as important predictor variables.
Results And Discussion: Mussel mortality was significantly higher in organically loaded burials when compared to control sediments after just 2 days.
