Title: Leveraging circular nutrients to improve the sustainability of peri-urban agriculture / Agriculture in the urban periphery (peri-UA) can potentially reduce its environmental impact through nutrient recovery from municipal solid and water waste, promoting local crops and displacing some dependency on imports.
L'estudi liderat per Juan Arosemena, investigador d'URBAG (Sostenipra, ICTA-UAB), i publicat a Waste Management , està generant una notable repercussió mediàtica. La setmana passada, Arosemena va participar al programa Vida Verda de Ràdio 4 per debatre sobre l'ús del compost a les ciutats i els seus beneficis ambientals.
Title: Closing the nutrient cycle in urban areas: The use of municipal solid waste in peri-urban and urban agriculture/ This research aims to determine the potential of organic municipal solid waste compost to supply the nitrogen-phosphorus-potassium demand of urban agriculture and the environmental benefits of replacing mineral fertilizer from a life cycle perspective.
Proof-of-Concept funded through URBAG project, January 2024-June 2025. What is hindering nutrient circularity in urban argiculture? The impoverished state and quality of the urban and peri-urban agricultural soil undermines nutrient circularity. Nutrient recovery is of no use unless soil is healthy!!
