Abstract Pollinators in agricultural landscapes are facing global decline and the main pressures include food scarcity pesticide usage. Although intensive poor habitats for wild pollinators, mass flowering crops may provide important resources, albeit monofloral short-term, which addition contain residues. We explored how landscape composition with a different proportion of oilseed rape (6%-65%) around Osmia bicornis nests affects floral diversity, contamination pesticides, energetic value provisions collected by bees as their offspring. The pollen from 28 taxa (6-15 per nest) were dominated Brassica napus (6.0-54.2%), Quercus (1.2-19.4%) Ranunculus (0.4-42.7%) found all 12 nests, but also Poaceae (1.2-59.9%, 11 nests) Acer (0.6-42%, 8 nests).

Abstract Wild bees are experiencing population declines globally. Despite urbanisation replacing habitat and forage with synthetic materials, urban residential gardens have the potential to become pollinator hotspots, increasing bee diversity abundance. We explored public knowledge attitudes towards bees, ‘bee-friendly’ interventions (BFIs) conducted by residents. reviewed motivations barriers which influence or prevent this, using town of Woking, England, as a case study. An online questionnaire was distributed in 2023 residents balconies. Results from 286 surveys showed 98.3% respondents performed ≥ 1 BFI most common action planting “pollinator-friendly” plants (75.9%). Sentiment positively correlated number BFIs performed, 94.8% felt about bees. Most participants indicated altruistic behind their performance BFIs. Implications for insect conservation: Though altruistically motivated undertake conservation wild performing at least one BFI, lack understanding is biggest barrier preventing action. Governments, policymakers, plant retailers should direct citizens organisations engage inform ecology improve provision within neighbourhoods.

Abstract Intensifying social-ecological urban challenges such as climate change, biodiversity loss and social injustices call for sustainable nature-based solutions. In this regard, bringing food production back into cities can be a major lever. However, so far systematic comparison is lacking between the environmental, social, economic sustainability of different types agriculture. This paper addresses research gap adds to current conceptually well empirically. Conceptually, we provide structured workbook how select operationalize indicators according their feasibility suitability comparative assessment agriculture types. Empirically, have been exemplified in evaluation community supported (CSA) vertical farming. Based on qualitative content analysis its vision guidelines, results suggest that CSA considered more form across all three dimensions. when taking account benefit farming an context increase efficiency, balancing shortcomings lack justice, conservation, quality by fostering hybrid model

Abstract Cities are a fragmented matrix of cultivated and semi-natural greenspaces. In rural agroecosystems, croplands attached to forest often have higher pollinator diversity than isolated due temporary spillover from adjacent forests. A similar dynamic could be at play in cities, where different semi-cultivated greenspaces interact via spillover. We studied flower-visiting insects between types urban greenspaces; community gardens that were forests, least 1 km forests away gardens. If was occurring, we expected see insect abundance the compared (and visa-versa). found no evidence insect-visitor for all metrics measured. did, however, find native bee species richness as with Unlike their counterparts, generally more diverse monoculture farms may offer flowering habitat needs such do not need into forest. Further investigation relative lack is required this ramifications plant-pollinator interactions cities. Our results suggest growing can attract pollinators regardless placement natural within landscape.
