Abstract As core constituents of healthy diets, fruits are often cultivated in temporally stable and structurally complex ecosystems that harbor high levels biodiversity. However, high-intensity orchard management can lessen the human environmental health benefits fruticulture. In present article, we argue increased emphasis on biological control could contribute to preventative fruit pests, weeds, diseases, resulting pesticide phasedown. Carefully calibrated increase provision ecosystem services by above- belowground biota, improve soil health, store atmospheric carbon. When tactically integrated with agroecological measures, behavior-modifying chemicals, or digital tools, helps conserve pollinator fauna, protect vertebrate communities, vegetation restoration outcomes. Its implementation can, however, give rise scientific social challenges will need be explored. By resolving adoption hurdles for at scale, society enjoy myriad nature-friendly production.

Gardens can benefit pollinators living in surrounding farmland landscapes, but the reason for their value is not clear. are no different from many semi-natural habitats terms of quantity floral resources (pollen and nectar) they produce, timing resource supply very different, which may explain value. We show that gardens provide 15% overall annual nectar landscapes Southwest UK, between 50% 95% during early spring late summer when supplies low. therefore reduce seasonal gaps experienced by bumblebees. Consistent with this pattern, bumblebee activity increased relative to summer. An agent-based model reinforces point, showing , garden enhances colony growth survival farmland. over 90% Great Britain within 1 km a positive actions gardeners could have widespread spillover benefits across country. Given distribution around world, we highlight important interplay pollinator ecology conservation.
