Urban and peri-urban agriculture (UPA) in West African countries is developing rapidly response to population growth changing consumer preferences. Furthermore, UPA offers opportunities secure income social integration for the urban poor. However, little known about household (HH) security effects of ongoing shift land use from crops that do not rely on insect pollinators fruit development (e.g., sorghum millet) pollinator-dependent crops. In our study we developed a Household Vulnerability Index (HVI) 224 HHs along rural–urban gradient Ouagadougou, Burkina Faso. The HVI indicates which degree total HH revenue could be affected by decline pollinators. specific relative reduction agricultural ranged 0 −0.83, HHs’ up 83%, depending crops’ level pollinator dependency. Half studied (n = 108) showed an remained unaffected Nevertheless, mean was highest HHs; making these most vulnerable loss pollination services. As areas changes insect-mediated services are expected, resilient systems must consider “pollinator-friendly” landscape management.

Ornamental plants rich in pollen and nectar are often marketed as "pollinator-friendly" by flower retailers. However, even though the attractive from a foraging perspective, i.e rich, bees other pollinating insects could be at risk exposure of pesticide residues on or used during production.

Abstract Like other urban green spaces, community gardens can act as biodiversity refugees, especially for small organisms like arthropods. In turn, arthropods provide important ecosystem pest control services to these agroecosystems. Thus, an often‐asked question among gardeners is how improve and surrounding areas natural enemies associated services. We examine local vegetation garden characteristics, well the landscape composition, affect ground‐dwelling beetles (Coleoptera: Carabidae Staphylinidae), spiders (Araneae), opilionids (Opiliones), ladybird Coccinellidae), all of which are predators. summer 2019, we collected predators, vegetation, ground cover, characteristic data from 10 in city Seattle, Washington. found that different groups with environmental variables at scales; probably related differences their dispersal capabilities, habits, diets. Floral (number flowers number species flower) had a negative effect on nonflying (spiders, opilionids, beetles), but not flying ones (ladybird beetles). The only taxon was significantly affected by landscape‐scale variable Opiliones, group examined exclusively disperses ground.

Abstract Many nature‐based solutions (NBS), including urban greenspaces, agriculture and agroforestry, depend upon animal‐pollinated plants to sequester carbon or provide other ecosystem services. Thus, long‐term success of these also depends resilient pollinator communities. Despite their importance functioning communities, a literature search revealed that 0%–3% papers on NBS related topics considered pollinators pollination. Pollinators were more likely be in the subgroup agricultural production, where 12.5% Conservation species interactions is essential conservation biodiversity sustained benefits NBS. By applying our understanding ecology plant‐pollinator mutualisms implementation NBS, we can promote under future climatic conditions. In particular, point need identify keystone pollinators, those contribute most maintenance, community stability function, leverage efforts. We further advocate for use phylogenetic trait‐based analyses understand characteristics associated with keystoneness.

ABSTRACT Urban gardens (UG) in densely populated cities serve as vital spaces, fostering community well‐being, biodiversity, and local food production. Yet, these face a growing threat from air soil contamination, particularly like Warsaw (Poland), where proximity to major roads, an international airport, industrial activities elevates the risks. This study, focusing on six UGs Warsaw, assessed (including potentially toxic elements (PTE) content using spectrophotometric method, toxicity health risks OECD 208 test method US EPA Hazard identification method) quality (PM 2.5 concentration) recorded at 1.5 m with calibrated Nephelometer. The results revealed that PTE concentrations remained low, dehydrogenase activity (DHA) phytotoxicity tests showing no effects. Both microbial plant growth were unaffected by pollution levels, suggesting maintain healthy ecosystems. Moreover, risk assessments confirmed significant associated exposure garden soils for either adults or children. reduction of PM levels within further highlights their role protective green spaces. These findings support idea UGs, even areas exposed urban stressors, do not pose environmental risks, making them safe, valuable components infrastructure.

Domestic gardens supply pollinators with valuable habitats, but the risk of exposure to pesticides has been little investigated. Artificial nesting shelters a red mason bee species (Osmia bicornis) were placed in two suburban and commercial fruit orchards determine contamination forage sources by pesticides. Larval pollen provisions collected from total 14 nests. They consisted mainly oaks (65–100% weight/sample), Brassicaceae (≤34% w/s) trees (≤1.6% w/s). Overall, 30 detected each sample contained mixture 11–21 pesticide residues. The residues significantly lower garden samples than orchard samples. difference was attributed abundant fungicides pyrimethanil boscalid, which sprayed present on average at 1004 ppb 648 samples, respectively. results suggested that can benefit domestic foraging floral less contaminated adjacent croplands.

Contrastingly, urban biodiversity positively contribute wellbeing.
