Temporal and Spatial Analysis of the Environmental State of the Valencia Plain Aquifer Area Using the Weighted Environmental Index (WEI)
2025Javier Rodrigo-Ilarri, Claudia P. Romero-Hernández, Sergio Salazar-Galán, María-Elena Rodrigo-Clavero · Sustainability · Spain (Valencia)
This article analyzes the impact of urban sprawl on the Valencia Plain aquifer system from 1990 to 2018 using the Weighted Environmental Index (WEI). Results show urban surfaces expanded by 70% and rainfed agricultural areas declined by over 59%, leading to a 9.2% reduction in environmental value (WEI decreased from 44.80 to 40.68). These changes threaten ecosystem sustainability and reduce the capacity to deliver ecosystem services.

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.

2022Angelica Mendoza Beltrán, Kelzy Jepsen, Martí Rufí-Salís, Sergi Ventura, Cristina Madrid‐López, Gara Villalba · The Science of The Total Environment · Spain (Barcelona)
This study mapped N2O emissions from peri-urban agriculture in the Metropolitan Area of Barcelona (AMB), Spain. Researchers spatially distributed factors like crop type, fertilizer use, and irrigation, creating N2O emission maps using crop-specific and Tier 1 IPCC emission factors (EFs). The study found that Tier 1 IPCC EFs estimated 15% more emissions (7718 kg N2O-N year−1) than crop-specific EFs (6533 kg N2O-N year−1) for the entire AMB, indicating higher emissions for rainfed crops with Tier 1 EFs and for irrigated horticultural crops with crop-specific EFs. The mapping helps evaluate spatial variability of key factors but carries uncertainties due to downscaling regional data.

2022Angelica Mendoza Beltrán, Roc Padró, María José La Rota-Aguilera, Joan Marull, Matthew J. Eckelman, Jacob Cirera, Annalisa Giocoli, Gara Villalba · The Science of The Total Environment · Spain (Barcelona)
This study implemented an attributional, regionalized, cradle-to-gate life cycle assessment (LCA) to assess 14 environmental impacts of peri-urban agriculture (peri-UA) in the Metropolitan Area of Barcelona (AMB). It found that vegetables and greenhouses, the prevalent peri-UA land uses, had the largest assessed impacts among all peri-UA land uses. European NPK mineral fertilizer production to cover nitrogen demand for these crops drives all impacts. For fruit crops, on-site nitrogen emissions drive marine eutrophication impacts, and for irrigated herbaceous crops, phosphate runoff drives freshwater eutrophication impacts.

2021Viktoria Shchurova · Current problems of architecture and urban planning · Ukraine (Kiev)
This article highlights the problems of the negative impact of the agricultural sector integrated into the central and middle zones of large cities. A critical view was formulated on the practical implementation of scientific and legislative documents, using the example of the city of Kiev, and strategies for reorganization, restrictions, or a complete ban on estate development in urban environments were analyzed. Specific plots of estate development in Kiev were identified as requiring reconstruction or complete renovation in accordance with the city's strategic development concept.

2018Marek Kopacki, Krystyna Rysiak, Mariusz Szmaraga · Annales Horticulturae · Poland (Lublin)
This 2014 study near Lublin, Poland, evaluated the decorative qualities and health of Tithonia rotundifolia in urban plantings, including a botanical garden and allotment gardens. Observations at the end of the vegetation period revealed disease symptoms, and mycological analysis of dead plant parts identified isolates of fungi from eleven genera. Dominant and dangerous pathogenic genera, Alternaria alternata and Botrytis cinerea, were found to affect T. rotundifolia.
