Spatial diversification of crop and non-crop habitats in farming systems is promising for enhancing natural regulation of insect pests. Nevertheless, results from recent syntheses show variable effects.One explanation is that the abundance and diversity of pests and natural enemies are affected by the composition, design and management of crop and non-crop habitats. Moreover, interactions between both local and landscape elements and practices carried out at different spatial scales may affect the regulation of insect pests. Hence, research is being conducted to understand these interdependencies.However, insects are not the only pests and pests are not the only elements to regulate in agroecosystems. Broadening the scope could allow addressing multiple issues simultaneously, but also solving them together by enhancing synergies. Indeed, spatial diversification of crop and non-crop habitats can allow addressing the issues of weeds and pathogens, along with being beneficial to several other regulating services like pollination, soil conservation and nutrient cycling. Although calls rise to develop multifunctional landscapes that optimize the delivery of multiple ecosystem services, it still represents a scientific challenge today. Enhancing interdisciplinarity in research institutions and building interrelations between scientists and stakeholders may help reach this goal. Despite obstacles, positive results from research based on such innovative approaches are encouraging for engaging 2 science in this path. Hence, the aim of the present paper is to offer an update on these issues by exploring the most recent findings and discussing these results to highlight needs for future research.

“…During the last decades, agricultural management turned previously heterogeneous landscapes into machine-efficient monocultures leading to a degradation and local depletion of natural landscape elements (NLEs) (Tilman et al, 2001;Vitousek et al, 1997). However, NLEs represent valuable habitats and food resources for many animals, for example, invertebrates and birds (Amy et al, 2015;Fuller & Gregory, 1995;Staley et al, 2012) delivering a range of ecosystem services such as biological pest control (Chaplin-Kramer, O'Rourke, Blitzer, & Kremen, 2011;Woodcock et al, 2016) and pollination services (Hipólito, Boscolo, & Viana, 2018;Lindgren, Lindborg, & Cousins, 2018).…”

Natural landscape elements (NLEs) in agricultural landscapes contribute to biodiversity and ecosystem services, but are also regarded as an obstacle for large‐scale agricultural production. However, the effects of NLEs on crop yield have rarely been measured. Here, we investigated how different bordering structures, such as agricultural roads, field‐to‐field borders, forests, hedgerows, and kettle holes, influence agricultural yields. We hypothesized that (a) yield values at field borders differ from mid‐field yields and that (b) the extent of this change in yields depends on the bordering structure. We measured winter wheat yields along transects with log‐scaled distances from the border into the agricultural field within two intensively managed agricultural landscapes in Germany (2014 near Göttingen, and 2015–2017 in the Uckermark). We observed a yield loss adjacent to every investigated bordering structure of 11%–38% in comparison with mid‐field yields. However, depending on the bordering structure, this yield loss disappeared at different distances. While the proximity of kettle holes did not affect yields more than neighboring agricultural fields, woody landscape elements had strong effects on winter wheat yields. Notably, 95% of mid‐field yields could already be reached at a distance of 11.3 m from a kettle hole and at a distance of 17.8 m from hedgerows as well as forest borders. Our findings suggest that yield losses are especially relevant directly adjacent to woody landscape elements, but not adjacent to in‐field water bodies. This highlights the potential to simultaneously counteract yield losses close to the field border and enhance biodiversity by combining different NLEs in agricultural landscapes such as creating strips of extensive grassland vegetation between woody landscape elements and agricultural fields. In conclusion, our results can be used to quantify ecocompensations to find optimal solutions for the delivery of productive and regulative ecosystem services in heterogeneous agricultural landscapes.

“…Over the long term, cutting to allow incremental growth would result in hedges that are taller and wider. However, if landowners do not want hedgerows that are larger eventually, they have the option of cutting hedgerows back to their original height and width periodically, or of rejuvenating hedgerows to encourage regrowth from the base using techniques such as coppicing or hedge laying (Amy et al ., ; Staley et al ., ), following a period of incremental cutting intensity. As well as providing food resources for Lepidoptera larvae and other invertebrates, hedges benefit invertebrates in other ways, such as through the provision of shelter against convective cooling for (ectothermic) species in otherwise often exposed agricultural landscapes (Merckx et al ., ).…”
