European agriculture must transform to confront the many challenges it faces, yet there are different sets of values that may underpin future agricultural change. However, we currently lack thorough understanding of the implications of operationalising these plural values for European land systems. In this article, we apply the IPBES Nature Futures...
Modern agriculture faces conflicting objectives—increasing agricultural production while preserving and fostering biodiversity. As intensive agricultural management threatens biodiversity, legal obligations aim to halt biodiversity loss and safeguard threatened species. In Switzerland, agricultural priority species have been defined to set environm...
Die zukünftige Agrar-und Ernährungspolitik strebt an, innovative, nachhaltige und gesamtheitliche Produktionssysteme in die Schweizer Landwirtschaft zu integrieren. Dazu ist es nötig, verschiedenste verfügbare Praktiken aus Sicht der Nachhaltigkeit objektiv bewerten zu können. Am Beispiel der Agroforstwirtschaft, einer vielversprechenden Form eines...
La future politique agricole et alimentaire vise à intégrer dans l'agriculture suisse des systèmes de production innovants, durables et globaux. Pour cela, il faut pouvoir évaluer en toute objectivité les pra-tiques existantes les plus diverses sous l'angle de la durabilité. En prenant l'exemple de l'agroforesterie, une forme prometteuse de système...

Ecological focus areas (EFAs) are a key element of European agri-environmental measures, which aim at mitigating the negative impact of intensive agricultural practices on biodiversity. They are mostly implemented at local scale, such as action-based EFAs (prescribed minimum biodiversity-friendly management) and result-based EFAs (prescribed minimu...
This study predicts the effects of climate change on crop yields, timber volumes and soil organic carbon in grassland, arable, ash woodland, poplar plantation, and silvopastoral and silvoarable systems in Northern Ireland. We modified a version of the biophysical Yield-SAFE agroforestry model that includes a RothC soil carbon module and also the ef...
Current agricultural practices in Europe are increasingly aggravating societal and environmental safety concerns. This creates social and regulatory pressures on farmers, which can lead to declining material and social status of farmers, farmer discontent, and anti-regulation protests. These tensions are rooted in conflicting value systems for agri...
Understanding how anthropogenic activities induce changes in the functional traits of arthropod communities is critical to assessing their ecological consequences. However, we largely lack comprehensive assessments of the long‐term impact of global‐change drivers on the trait composition of arthropod communities across a large number of species and...
Sustainable intensification (SI) responds to the concurrent challenges of increasing food production while reducing the environmental impacts of agriculture. As an early disclosure of innovation, patents are a useful indicator of technology market potential. However, we lack understanding of the extent to which current agricultural technology paten...
In Europe, agri-environment schemes (AES) are a key instrument to combat the ongoing decline of farmland biodiversity. AES aim is to support biodiversity and maintain ecosystem services, such as pollination or pest control. To what extent AES affect crop yield is still poorly understood. We performed a systematic review, including hierarchical meta...
Targeted conservation and promotion of wild bees in agroecosystems requires understanding of relationships between different groups of bees and available floral resources across land-use types during the season and at the landscape scale. Here, we quantified floral resource amount and diversity across habitat types at different times during the sea...
Um die Vielfalt von Lebewesen in der Schweizer Agrarlandschaft zu erhalten und zu fördern, werden verschiedene Massnahmen umgesetzt. Eine davon sind Biodiversitätsförderflächen. Drei Kategorien von Biodiversitätsförderflächen (BFF) werden unterschieden: BFF QI werden mit spezifischen Auflagen biodiversitätsfördernd bewirtschaftet. BFF QII beherberg...
Farming in Europe has been the scene of several important socio-economic and environmental developments and crises throughout the last century. Therefore, an understanding of the historical driving forces of farm change helps identifying potentials for navigating future pathways of agricultural development. However, long-term driving forces have so...
Grasslands host a significant share of Europe’s species diversity but are among the most threatened vegetation types of the continent. Resurvey studies can help to understand patterns and drivers of changes in grassland diversity and species composition. However, most resurveys are based on local or regional data, and hardly reach back more than ei...
Many studies have explored farmers' perspectives on biodiversity and ecosystem services, but fewer qualitative and cross-country comparisons exist. We develop a socio-ecological system to analyse agricultural landscape services, biodiversity, and drivers that have affected these services in recent decades. Via a systematic stake-holder mapping and...
Diverse agricultural land uses are a typical feature of multifunctional landscapes. The uncertain change in the drivers of global land use, such as climate, market and policy technology and demography, challenges the long-term management of agricultural diversification. As these global drivers also affect smaller scales, it is important to capture...
Darüber, wie sich die Schweizer Landwirtschaft entwickeln soll, gibt es unterschiedliche Vorstellungen. Wir haben die landwirtschaftlichen Veränderungen der vergangenen zwanzig Jahre in drei Schweizer Regionen untersucht. Um die Richtung der landwirtschaftlichen Entwicklung zu be-urteilen, haben wir sie mit drei unterschiedlichen Visionen vergliche...
Life cycle assessment (LCA) aims at providing standardized evaluations of processes involving resource use, human health, and environmental consequences. Currently, spatial dependencies are most often neglected, though they are essential for impact categories like biodiversity. The "Swiss Agricultural Life Cycle Assessment for Biodiversity (SALCA-B...
Agricultural intensification has profoundly changed agricultural landscapes with important biodiversity impacts. There is increasing knowledge on the general effects of landscape structure and management practices on plant and animal species but understanding the role of surrounding landscape structure for patch-scale biodiversity is more complex....
Agricultural expansion and intensification are key drivers of biodiversity decline. There is mounting evidence that modern farming impacts the effectiveness of protected areas as one of the key instruments of biodiversity conservation through, for example, eutrophication, pesticide emissions or increasing access to remote areas [1]. This is increas...
Climate and land-use changes are main drivers of insect declines, but their combined effects have not yet been quantified over large spatiotemporal scales. We analysed changes in the distribution (mean occupancy of squares) of 390 insect species (butterflies, grasshoppers, dragonflies), using 1.45 million records from across bioclimatic gradients o...
Zusammenfassung Rund 30 % der Fruchtfolgeflächen der Schweiz (137 000 ha) sind drainiert. Zunehmend stellt sich für die älteren Drainagen die Frage der Erneuerung und der entsprechenden Kostenfolgen. Gleichzeitig sind Feuchtlebensräume in der Agrarlandschaft durch die grossflächige Entwässerung selten geworden. Die Entwässerung beeinflusst verschie...

De plus en plus, la question de la rénovation des anciens drainages se pose et avec elle, celle des conséquences financières qui en découlent. Parallèlement, le...
Agriculture plays a central role in achieving most Sustainable Development Goals (SDGs). Sustainable intensification (SI) of agriculture has been proposed as a promising concept for safeguarding global food security, while simultaneously protecting the environment and promoting good quality of life. However, SI often leads to context-specific susta...
It has been shown that the COVID-19 pandemic affected some agricultural systems more than others, and even within geographic regions, not all farms were affected to the same extent. To build resilience of agricultural systems to future shocks, it is key to understand which farms were affected and why. In this study, we examined farmers' perceived r...
Floral resources are crucial for wild pollinators. Identifying the spatio-temporal floral resource use of wild pollinators and effects of resource distribution on their development might help to promote them and their pollination services to crops in agricultural landscapes.
We established populations of Osmia cornuta and Osmia bicornis, two solita...
The slow adoption by the agricultural sector of practices to promote biodiversity are thought to originate from three interrelated issues. First, we know little about which incentives effectively motivate farmers to integrate biodiversity into daily farm management. Second, few studies so far have produced evidence that biodiversity-based approache...
A range of intensifying pressures is making the future of European agriculture dynamic and contested. Insights into these pressures are needed to inform debates about the future of the sector. In this study, we use a foresight approach to identify, quantify and map megatrends. Megatrends are long-term driving forces which are observable today and w...
Context
Flowering plants can enhance wild insect populations and their pollination services to crops in agricultural landscapes, especially when they flower before the focal crop. However, characterizing the temporal availability of specific floral resources is a challenge.

Theme: Biodiversity Abstract Traditional agroforestry systems such as Dehesas/Montados, high-stem fruit orchards, hedgerow landscapes (bocage, Knick) or woody pastures are renowned for biodiversity and ecosystem services. Can we expect similar benefits from modern temperate agroforestry systems such as alley cropping? Here we summarize results of r...
Orchard meadows, a traditional agroforestry system in Switzerland combining the dual use fruit and fodder production, are declining, even though the farmland managed under agri-environmental schemes (AES) has been expanding. Despite increasing interest in agroforestry research for developing sustainable agriculture, it is poorly understood how subs...
Agri-environmental schemes (AES) aimed at promoting farmland biodiversity are a key agricultural policy instrument in Switzerland. While the share of farmland managed under AES has expanded, traditional orchard meadows, regarded as agrobiodiversity hotspots, are declining. It is not clear yet what role AES play in maintaining orchard meadows, consi...
Seventy five percent of the world's food crops benefit from insect pollination. Hence, there has been increased interest in how global change drivers impact this critical ecosystem service. Because standardized data on crop pollination are rarely available, we are limited in our capacity to understand the variation in pollination benefits to crop y...
Context
Predatory insects contribute to the natural control of agricultural pests, but also use plant pollen or nectar as supplementary food resources. Resource maps have been proposed as an alternative to land cover maps for prediction of beneficial insects.
Objectives
We aimed at predicting the abundance of crop pest predating insects and the pe...
There is broad agreement that agriculture has to become more sustainable in order to provide enough affordable, healthy food at minimal environmental and social costs. But what is "more sustainable"? More often than not, different stakeholders have opposing opinions on what a more sustainable future should look like. This normative dimension is rar...
Crop Pollination by Wild and Honey Bees in Switzerland: Importance, Potential for Yield
Increases and Support Measures
Pollinating insects such as the domestic honey bee as well as numerous wild-bee species and other wild pollinators play an essential role in the provision of pollination services for crop production and wild plants in agroecosyst...
Conversion of semi-natural habitats, such as field margins, fallows, hedgerows, grassland, woodlots and forests, to agricultural land could increase agricultural production and help meet rising global food demand. Yet, the extent to which such habitat loss would impact biodiversity and wild species is unknown. Here we survey species richness for fo...
Rural Europe encompasses a variety of landscapes with differing levels of forest, agriculture, and agroforestry that can deliver multiple ecosystem services (ES). Whilst provisioning and regulating ES associated with individual land covers are comparatively well studied, less is known about the associated cultural ES. Only seldom are provisioning,...
Context
Agroecology combines agronomic and ecological concepts. It relies on the enhancement of biodiversity and related ecosystem services to support agricultural production. It is dependent on biological interactions for the design and management of agricultural systems in agricultural landscapes.
Objectives
We review the role of landscape ecolo...
In Switzerland-as in many other European countries-Agroforestry systems are long-term investments for farmers. The woody component provides income earliest after 5 years from a continuous fruit or energy production and latest after 30 or 100 years when timber is harvested in Europe. To guarantee a sustainable and resilient production over this whol...
Standard size cherry trees with high stems are a major element of traditional agroforestry systems in northern Switzerland. Nowadays the cultivation of standard fruit trees with cherries is under pressure in this area. High harvest and crop management costs combined with declining income make the cultivation of high stem trees in combination with g...
Two major targets of the Sustainable Development Goals of the United Nations (https://sustainabledevelopment.un.org/) are the attainment of “Zero Hunger” and “Life on Land” by 2030. While “Zero Hunger“ refers to the end of hunger and achievement of food security and improved nutrition through the practice of sustainable agriculture, Life on Land im...
Agroforestry is a traditional land use system that may contribute to the solution of environmental problems in agriculture. Agroforestry is the practice of deliberately integrating woody vegetation (trees or shrubs) with crops and/or animal systems to benefit from the resulting ecological and economic interactions. Recent research indicates that a...

There is widespread consensus among scientists, policy makers, and practitioners that agriculture should become more sustainable, while maintaining the ability to meet future food demand. However, there are still many diverging views on what sustainable intensification means, and how to get there. In this article, we present a conceptual framework...
Agroforstsysteme, die Kombination von Gehölzen und landwirtschaftlicher Nutzung auf der gleichen Fläche, haben als Hochstamm-Feldobst (= Streuobst), Waldweiden und Kastanienselven eine lange Tradition in der Schweiz. In den letzten Jahren wurden die Systeme in moderner Form reaktiviert, d.h. ihr Pflanzdesign wurde an die Mechanisierung angepasst un...
Floral plantings are promoted to foster ecological intensification of agriculture through provision-ing of ecosystem services. However, a comprehensive assessment of the effectiveness of different floral plantings, their characteristics and consequences for crop yield is lacking. Here we quantified the impacts of flower strips and hedgerows on pest...
Elucidating the diets of insect predators is important in basic and applied ecology, such as for improving the effectiveness of conservation biological control measures to promote natural enemies of crop pests. Here, we investigated the aphid diet of two common aphid predators in Central European agroecosystems, the native Coccinella septempunctata...
There is an increasing demand to study the long-term effects of land use from both local farm and wider societal and environmental perspectives. This study applied an approach to evaluate both the financial profitability of arable, agroforestry, and tree-only systems and the wider societal benefits over a period of 30-60 years. The biophysical inpu...
Mosaics of agricultural land, forests, and other semi-natural areas represent landscapes providing valuable habitats and resources for various insect groups. We investigated the added value of agroforestry, the combination of crops or grasslands with woody elements, for important pollinating insects e.g. wild bees and associated pollination service...
