The food-water-climate nexus of green infrastructure: Examining ecosystem services trade-offs of peri-urban agriculture
2024Ricard Segura, Johannes Langemeyer, Alba Badía, Sergi Ventura, Jaime Vila-Traver, Gara Villalba · The Science of The Total Environment · Spain (Barcelona)
A study in the Metropolitan Area of Barcelona, Spain, investigated the impacts of peri-urban agricultural expansion on the food-water-climate nexus using urban metabolism and atmospheric-biosphere models across four land-use scenarios. While expansion increased food production and irrigation water requirements, replacing natural non-forested and forest areas for peri-urban agriculture was predicted to reduce net ecosystem productivity by up to 18.5% and total carbon stocks by 3.3%. Irrigated peri-urban agriculture potentially reduced near-surface temperatures by 0.7°C, though reductions in the densest urban areas were minimal.

2024Catherine Oliver · Transactions of the Institute of British Geographers · United Kingdom (London)
This paper examines urban chicken-keeping in London, where urban spaces are transformed to accommodate chickens. It argues that the human-imposed design of urban barnyards is often impractical for chickens, leading to lawns being torn up, plants demolished, and vegetable patches consumed. Additionally, chickens are vulnerable to local foxes, highlighting that chickens' behaviors and territoriality often overflow their assigned space, challenging human design intentions.
