2026Farooq Ahmad Khan, Zaffar Mahdi Dar, Saddam Hussain, Sumati Narayan · · Global
The global food system contributes approximately 31% of anthropogenic greenhouse gas emissions, while rapid urbanization is projected to have nearly 70% of the global population in urban areas by 2050. This demographic shift intensifies the carbon footprint of food supply chains due to long-distance transportation and energy use. Urban and peri-urban agriculture (UPA) is presented as a strategic opportunity to localize food production, reduce carbon footprints, and contribute to carbon-negative farming systems that both decrease and sequester atmospheric carbon.

2025Piaopiao Ke, Beñat Olascoaga, Pasi Kolari, Outi Tahvonen, Sami Haapanala, Tom Kokkonen, Leena Järvi, Markku Kulmala, Anna Lintunen · Urban forestry & urban greening · Finland
A year-round eddy covariance and soil chamber measurement in an urban allotment garden in southern Finland showed it functioned as a net CO₂ source (0.69 kg m⁻² yr⁻¹) despite 77% vegetation cover. High respiratory emissions (4.7 kg m⁻² yr⁻¹) exceeded photosynthetic uptake (4.0 kg m⁻² yr⁻¹), likely due to elevated soil organic carbon (13.4 ± 8.7%) and high soil C:N ratio from management amendments. These findings challenge assumptions about urban gardens as inherent carbon sinks and suggest carbon-smart management practices are needed.
