A new economic analysis found that developing countries pay less for the nutrition in seafood imports than developed countries, largely because developed countries pay a premium for non-nutritional attributes such as convenience. The findings suggest that disruptions to the global seafood trade could affect food and nutritional security in countries that depend on seafood imports for meeting their dietary needs.

Ocean waters are getting greener at the poles and bluer toward the equator, according to a new study. The change reflects shifting concentrations of a green pigment called chlorophyll made by photosynthetic algae at the base of the ocean food chain.

Because most seafood is imported, tariffs will cause Americans to eat less heart-healthy seafood and more heart-unhealthy red meat.

Small-scale fisheries play a significant but overlooked role in global fisheries production and are key to addressing hunger and malnutrition while supporting livelihoods around the world, according to research featured on the cover of Nature.

Reforestation in low- and middle-income countries can remove up to 10 times more carbon dioxide from the atmosphere at lower cost than previously estimated, making it a potentially more effective option to fight climate change.

Xavier Basurto is broadly interested in how people in small communities successfully organize themselves for collective action. His recent talk described his work in advancing the understanding of non-colonialist sustainability science: the prospects and limitations of self-organization, or self-governance, for social-ecological sustainability, particularly in the Global South.

A new study by researchers at Penn State University, 51±¬ÁÏ, and the University of Saskatchewan suggests not all of the nearly 2,000 species of ground beetles found in North America will thrive under climate change. Some could decline. And that could have far-reaching implications for agriculture, forestry, and conservation.

The Illuminating Hidden Harvests Report culminates a collaborative research effort led by the Food and Agriculture Organization of the United Nations (FAO), 51±¬ÁÏ and WorldFish examining the multifaceted contributions of small-scale fisheries to sustainable development.

The sustainability of North American forests depends on trees’ ability to produce seeds and seedlings that can survive and grow in a changing climate. A new 51±¬ÁÏ-led research initiative with more than $2 million in funding from the National Science Foundation aims to help boost their odds of success.

A forest’s ability to regenerate after devastating wildfires, droughts or other disturbances depends largely on seed production. Findings from two new studies led by 51±¬ÁÏ researchers could boost recovery and replanting after these disasters by providing foresters with new guidance on which tree species produce more seeds and how their productivity can vary from location to location.
