Human activities drive a wide range of environmental pressures, including habitat change, pollution and climate change, resulting in unprecedented effects on biodiversity1,2. However, despite decades of research, generalizations on the dimensions and extent of human impacts on biodiversity remain ambiguous. Mixed views persist on the trajectory of...

Regional and national food policies must seek to attain equilibrium among social, economic, political, agricultural , and environmental factors. As a developmental objective, food self-sufficiency (FSS) responds to a region's need for increased autonomy and control over its own food supply. In this systematic review, we employed the Preferred Repor...

While many herbicide active substances have been banned and weed infestation is a major threat to crop productivity, it is still unknown to what extent natural weed control provided by seed predators can help farmers manage weed communities. We aim to quantify the contribution of seed predators to crop productivity through weed control and to evalu...

While the temporal stability of communities of natural enemies in agroecosystems is crucial to sustain pest control services over time, little is known about what drives this stability. Using a 6-year dataset composed of carabid collections, together with local and landscape-level management descriptors from 57 arable fields in France, we examined...

Decline in species richness as well as changes in community evenness or functional diversity have been hypothesised to jointly affect ecosystem functioning. However, disentangling the relative effects of these changes in community structure is hard as these different aspects often covary with species richness in real‐world ecosystems. In this study...

Biological control is a key ecosystem service in arable lands, but its effectiveness varies according to environmental and biotic contexts. Cascading interactions between several trophic levels can affect natural enemies and their efficacy. Here, we analysed how multitrophic interactions drive weed seed control under contrasting farming systems and...

The evidence that most agricultural landscapes are failing to deliver on biodiversity conservation and ecosystem services provision suggests that future landscapes will need to be more explicitly designed. Although recent research has produced a number of ecological and social principles that should form the basis of agricultural landscape design p...

Understanding the effects of the huge diversity of cropping systems on local biodiversity is challenging but necessary to implement agroecological systems. Through a functional approach, the translation of cropping systems into resource and disturbance gradients is a promising way to decipher the relationship between cropping systems and biodiversi...

Natural pest control results from ecological functions like predation or parasitism. Such functions are supplied by an array of natural enemies embedded in a large community of interacting species. In this chapter, we discuss the extent to which natural enemy composition affects pest demography and we highlight the importance of considering how spe...

Understanding how community composition of service‐providing organisms affects ecosystem functioning is a key challenge in ecology. Although it has been proposed that taxonomic diversity and functional traits mediate this relationship, how several facets of community structure affect the delivery of key ecosystem services remains to be explored. In...

Ecological intensification of agriculture (EIA) aims to assure food security by harnessing ecosystem services while minimizing external inputs and environmental harms. One manifestation of EIA proposed worldwide is agroecological farming, which will affect future landscapes, biodiversity and make assurance of crop yields more reliant on management...

Organic farming is seen as a prototype of ecological intensification able to conciliate crop productivity and biodiversity conservation in agricultural landscapes. However, how natural enemies, an important functional group supporting pest control services, respond to organic farming at different scales and in different landscape contexts remain un...

Neonicotinoids have been banned in France. This article (in french) evaluates the limited consequences for french viticulture. Only one neonicotinoid with different formulations is currently used, mainly against leafhoppers. In this paper we discuss the incidence for viticulture and present reasons motivating the ban. Aurhors 1 and 4 where experts...

While organic farming practices, which are often promoted as models of ecological intensification, generally enhance biodiversity, their effects on the delivery of ecosystem services, such as biological pest control, are still unknown. Here, using a multi‐scale hierarchical design in southwestern France, we examined the effects of organic farming a...

Ecological intensification of agro-ecosystems, based on the optimization of ecological functions such as biological pest control, to replace agrochemical inputs is a promising route to reduce the ecological footprint of agriculture while maintaining commodity production. However, the performance of organic farming, often considered as a prototype o...

Grape is a major crop, covering 7.5 M ha worldwide, that is currently being confronted with three main challenges: intensive pesticide use that must be reduced, invasion by new pests/diseases, and climate change. The biological control of pests and vectors would help address these challenges. Here, we review the scientific literature on the biologi...

Identifier les leviers permettant de stimuler la régulation naturelle des bioagresseurs tout en préservant la biodiversité est indispensable pour concevoir des paysages agricoles fonctionnels. A partir d’une méta-analyse et d’une étude empirique reposant sur 42 parcelles viticoles localisées dans Nouvelle Aquitaine (France), nous avons cherché à év...

Organic farming is a promising way to reduce pesticide use but increasing the area under organic farming at the landscape scale could increase pest infestations and reduce crop productivity. Examining the effects of organic farming at multiple spatial scales and in different landscape contexts on pest communities and crop productivity is a major st...

Natural pest control by predators and parasitoids is an important ecosystem service supporting crop production. It is now well known that the proportion of semi-natural habitats as well as organic farming enhance abundance and species richness of natural enemies in agroecosystems. However, few studies have examined how these environmental variables...
