CompostCommunityOrganic cycleApplying recovered nutrients and pruning waste to enrich and regenerate agricultural soils in urban agriculture: Effects on emissions and yield of spinach and sweet potato
2026Guido Evangelista, Juan David Arosemena, Gaia Stringari, Joan Romanyà, Xavier Gabarrell, Francesco Orsini, Gara Villalba · Agriculture Ecosystems & Environment · Global
This study evaluated the application of 150 t ha-1 of ramial chipped wood (RCW) to degraded peri-urban agricultural soils, comparing its effects on yield, soil health, and greenhouse gas emissions for spinach and sweet potato. Spinach grown with RCW showed the lowest productivity (1.16 – 0.32 kg m-2) among treatments, while sweet potato achieved the highest yield (1.72 – 1.99 kg m-2). High RCW doses initially led to higher CO2 emissions but significantly reduced N2O emissions for spinach (from 0.36 kg ha-1 to 0.07 kg ha-1) and enhanced soil organic carbon and nitrogen stocks for sweet potato, indicating agronomic and environmental trade-offs.

2026Niloofar Shoja Razavi, Kefeng Zhang, Veljko Prodanović · Agricultural Systems · Global
This review assessed the agronomic suitability and contaminant profiles of five alternative water sources (greywater, blackwater, groundwater, rainwater, and stormwater) for urban crop irrigation. Four nature-based solution (NBS) technologies (constructed wetlands, biofilters, green roofs, and green walls) were evaluated as pre-treatment systems, with hybrid systems demonstrating over 97% removal efficiency for contaminants. Economic viability was highly dependent on crop selection; high-value crops like tomatoes and sweet peppers irrigated with treated groundwater showed the greatest profitability, while faba beans remained unviable regardless of treatment. Policy analysis identified substantial governance gaps, including inconsistent enforcement, limited public acceptance, and minimal regulatory guidance specific to urban agricultural water reuse.
