While MPAs covered 11.4% of EU national waters in 2022, 0.2% were fully or highly protected. As much as 86% of MPA coverage showed low levels of protection or would not be considered compatible with conservation objectives, as they allow industrial activities. Most MPA coverage showed minimal protection across member states, sea regions, and legal types of MPAs. The EU MPA network likely provides limited ecological outcomes.

Here, we address the knowledge gap by investigating SSFs’ perspectives and conflicts related to coastal development to inform equitable and inclusive policy formation. Our findings highlight the multiple impacts on different fishing communities, including marine traffic, blast fishing, industries, and ports, emphasizing contextual conflicts associated with different levels of coastal development.

However, widespread adoption of diverse rotations is limited by economic uncertainty, lack of incentives, and limited information about long-term outcomes. Here, we combined 36,000 yield observations from 20 North American long-term cropping experiments (434 site-years) to assess how greater crop diversity impacts productivity of complete rotations and their component crops under varying growing conditions. Maize and soybean output increased as the number of species and rotation length increased, while results for complete rotations varied by site depending on which crops were present. Diverse rotations reduced rotation-level output at eight sites due to the addition of lower-output crops such as small grains, illustrating trade-offs.

Our study addresses this gap by examining how political, economic, and structural features of food systems enable the meat industry to externalize costs of production and perpetuate ecological and social harms. Here, we analyze three case studies from different stages of global supply chains, revealing a highly concentrated meat industry, close industry-government ties, reduced regulatory oversight, and entrenched cultural norms about meat’s significance to food security.
