“…Landscape context (composition and heterogeneity of land use types) in agricultural systems has been shown to have an important influence on species richness and abundance for a range of taxa (bumble bees [Rundlo¨f et al 2008]; all bee species [Holzschuh et al 2007, Williams et al 2010; hoverflies [Kleijn and van Langevelde 2006]; arable plants [Roschewitz et al 2005]). Consistent with these studies, we found that differences in species number between sown forage patches and existing conventionally managed field edges (control patches) increased with the proportion of arable land in the landscape.…”

“…It is also clear that farming systems can interact with landscape context to determine local bee diversity, such that, for example, organic farming has a stronger positive effect on bee diversity in homogeneous landscapes (Holzschuh et al 2007, Rundlo¨f et al 2008. However, while it has been proposed that conservation measures promoting the sowing of flower mixtures should focus on more intensively farmed (though not highly simplified) landscapes , Isaacs et al 2009, there is no experimental evidence for this.…”

Abstract. The global decline of insect pollinators, especially bees, is cause for concern, and there is an urgent need for cost-effective conservation measures in agricultural landscapes. While landscape context and habitat quality are known to influence species richness and abundance of bees, there is a lack of evidence from manipulative field experiments on bees' responses to adaptive management across differently structured landscapes. We present the results of a large-scale study that investigated the effects of a targeted agri-environment scheme (AES) on bumble bees (Bombus spp.) over three years in the United Kingdom. Forage patches of different sizes were sown with a conservation flower mixture across eight sites covering a broad range of agricultural land use types. Species richness and worker densities (especially of the longer-tongued Bombus species for which the mixture was targeted) were significantly higher on sown forage patches than on existing non-crop control habitats throughout the three-year study, but the strength of this response depended on both the proportions of arable land and abundance of herbaceous forb species in the surrounding landscape. The size of sown patches also affected worker density, with smaller patches (0.25 ha) attracting higher densities of some species than larger patches (1.0 ha). Our models show that a targeted AES can deliver greater net benefits in more intensively farmed areas, in terms of the number and species richness of bumble bees supported, than in heterogeneous landscapes where other foraging habitats exist. These findings serve to strengthen the evidence base for extending agri-environment schemes to boost declining pollinator populations to a larger number of agricultural landscapes across the globe.

“…In bees (Box 4), relationships between habitat loss and species traits have been intensively studied (Krauss et al, 2009;Moretti et al, 2009;SteffanDewenter et al, 2006), with diet width and sociality being especially important (Aizen and Feinsinger, 1994a,b;Klein et al, 2003;Ö ckinger and Smith, 2007;Rundlöf et al, 2008;. Social bees are expected to outperform solitary taxa in harvesting resources because of their higher foraging and food-provision capacity (e.g.…”

“…Such methods often involve a combination of different types of crop-annual, perennial and woody species-such as agroforestry and agro-silvicultural systems with a combination of crops and fruit-trees, such as alley cropping or home gardens [29]. Biological diversity is promoted and enhanced by the crop diversity and by production methods that will increase biodiversity of different organism groups, e.g., pollinators [30]. Further, such production systems promote a diverse landscape structure, which facilitates the maintenance and production of a number of other ecosystem services, not least recreation by attracting visitors (cf.…”

Peri-Urban Food Production and Its Relation to Urban Resilience

Food production on the urban-rural fringe is under pressure due to competing land uses. We discuss the potential to improve resilience for urban-rural regions by enhancing food production as part of multifunctional land use. Through studies of peri-urban land in the regions of Gothenburg (Sweden), Copenhagen (Denmark) and Gent (Belgium), recent developments are analysed. Arable farming has been declining since 2000 in all three areas due to urban expansion and recreational land use changes. In city plans, networks of protected areas and green spaces and their importance for human wellbeing have been acknowledged. Policies for farmland preservation in peri-urban settings exist, but strategies for local food production are not expressed in present planning documents. Among the diversity of peri-urban agricultural activities, peri-urban food production is a developing issue. However, the competing forms of land use and the continuing high dependence of urban food on global food systems and related resource flows reduces peri-urban food production and improvements in urban food security. The positive effects of local food production need to be supported by governance aiming to improve the urban-rural relationship. The paper discusses the resilience potential of connecting urban-rural regions and re-coupling agriculture to regional food production.
