“…This can include woodlots, hedgerows, and seminatural habitats on the farm or landscape scale. Although there are recognized principles for management of farming landscapes for beneficials (Bianchi, 2022;Haan et al, 2021;Petit et al, 2023), a review of a large number of studies found that benefits for pest control can be variable, sometimes with tradeoffs that can cause reduced yields (Karp et al, 2018).…”

Climate change is expected to alter pressure from insect pests and the effectiveness of insect pollinators across diverse agricultural systems globally. In response to warming, insects are undergoing or are projected to undergo shifts in their geographic ranges, voltinism, abundance, and phenology. Effects on the focal insect species can be affected directly or indirectly, through their interactions with other species at higher and lower trophic levels. These climate‐driven effects are complex and as a result variable, sometimes increasing pest pressure or reducing pollination and sometimes with opposite effects depending on climatic baseline conditions and the interplay of contributing drivers. This uncertainty prevents effective responses. Furthermore, in addition to effects of climate change on insect pests and pollinators, projected and ongoing climate change is incentivizing changes in cropping systems such as altered tillage and increasing diversification and intensification with the potential to alter pests and pollinators as great as climate itself. Preparing for this uncertainty must be included in a framework for “Climate‐smart Integrated Pest and Pollinator Management,” as a component of agricultural production under climate change.

Faced with the biodiversity extinction crisis and climate change, alternative approaches to food production are urgently needed. Decades of chemical-based weed control have resulted in a dramatic decline in weed diversity, with negative repercussions for agroecosystem biodiversity. The simplification of cropping systems and the evolution of herbicide resistance have led to the dominance of a small number of competitive weed species, calling for a more sustainable approach that considers not only weed abundance but also community diversity and composition. Agroecological weed management involves harnessing ecological processes to minimize the negative impacts of weeds on productivity and maximize biodiversity. However, the current research effort on agroecological weed management is largely rooted in agronomy and field-scale farming practices. In contrast, the contributions of landscape-scale interventions on agroecological weed management are largely unexplored (e.g., interventions to promote pollinators and natural enemies or carbon sequestration). Here, we review current knowledge of landscape effects on weed community properties (abundance, diversity, and composition) and seed predation (a key factor in agroecological weed management). Furthermore, we discuss the ecological processes underlying landscape effects, their interaction with in-field approaches, and the implications of landscape-scale change for agroecological weed management. Notably, we found that (1) landscape context rarely affects total weed abundance; (2) configurational more than compositional heterogeneity of landscapes is associated with higher alpha, beta, and gamma weed diversity; (3) evidence for landscape effects on weed seed predation is currently limited; and (4) plant spillover from neighboring habitats is the most common interpretation of landscape effects on weed community properties, whereas many other ecological processes are overlooked. Strikingly, the drivers of weed community properties and biological regulation at the landscape scale remain poorly understood. We recommend addressing these issues to better integrate agroecological weed management into landscape-scale management, which could inform the movement towards managing farms at wider spatiotemporal scales than single fields in a single season.
