Drivers of nocturnal and diurnal pollinating insect declines in urban landscapes
2025Emilie E. Ellis, S. Campbell, Jill L. Edmondson · Proceedings of the Royal Society B Biological Sciences · Global
A large-scale assessment across three cities found up to a 43% reduction in species richness of bees, hoverflies, and nocturnal moths in urban horticultural sites along urbanization gradients. These declines are driven by taxon-specific landscape changes like reduced tree canopy and semi-natural habitat. Moths and hoverflies were particularly sensitive to urbanization compared to bees, indicating a wide range of pollinators are under threat in urban landscapes.

2025Blessing Nyamasoka‐Magonziwa, Esther Simango, Hatirarami Nezomba · Frontiers in Agronomy · Zimbabwe (Chitungwiza)
This study evaluated climate-smart crop production practices by urban farmers in Chitungwiza District, Zimbabwe, and their effects on household diets. Mixed methods research, including focus group discussions with four farmer groups and interviews with 107 households in 2022, classified only 23% of farmers as climate-smart. While climate-smart crop production positively influenced household diets, with climate-smart households having a significantly higher Household Dietary Diversity Score (3.3 vs. 2.9; p=0.02), there were no significant differences in maize yield between climate-smart and non-climate-smart farmers (2.10 t/ha vs. 2.27 t/ha, respectively, in the 2020/2021 season).

2025Sergi Ventura, J.R. Armengol Miró, David Camacho-Caballero, Enric Casellas, Ricard Segura-Barrero, Alberto Martilli, gara villalba · Urban Climate · Spain (Barcelona)
This study used the Pseudo Global Warming method and WRF model to assess urban heat adaptation strategies in the Metropolitan Area of Barcelona. Three strategies were evaluated: increasing rooftop albedo, implementing irrigated sedum green roofs, and increasing peri-urban agriculture and urban parks. While increasing rooftop albedo provided the greatest daytime cooling (−1.75 °C), and green roofs and peri-urban agriculture showed moderate regulation, none of the strategies fully counterbalanced the projected 6 °C temperature increase by 2100, indicating a limited capacity of these adaptations under severe warming scenarios.

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.
