Cultivating Resilience in the Informal City: A Systematic Review of Urban Agriculture's Multidimensional Outcomes in Slum Contexts

Geography Compass, Volume 20, Issue 3, March 2026.
ABSTRACT Urban agriculture (UA) in slums represents a vital yet under‐researched strategy for enhancing food security and community resilience in marginalised urban areas. This systematic review of 104 studies reveals stark contrasts in theoretical approaches: Global North scholarship frames UA through lenses of racial capitalism and gentrification ...

Detection and Genomic Characterization of Novel Respiratory Viruses in US and Mexican Cattle Farms

Transboundary and Emerging Diseases, Volume 2026, Issue 1, 2026.
Respiratory virus infections in cattle cause an estimated more than $1 billion in production losses and can threaten human health. During February 2024 to May 2025, we employed a One Health approach to surveil for respiratory viruses among cattle, farm workers, and environmental samples from 11 US and Mexican beef or dairy cattle farms.
