Examining linkages among multiple sustainable development outcomes: does the productive safety net program increase on-farm agrobiodiversity?

In Ethiopia, on-farm agrobiodiversity and the Productive Safety Net Program (PSNP) play a key role in building smallholders’ resilience. However, the impact of PSNP on on-farm agrobiodiversity is not yet well investigated. In this paper, we develop an analytical framework that links PSNP participation to on-farm agrobiodiversity. Both diverse farming systems and PSNP require labour inputs while providing income stabilization, which might result in a negative relationship between the two. Conversely, higher income from PSNP might allow farmers to increase their long-term on-farm investments, as opposed to the strategies oriented toward the highest immediate profit or calorie intake outcome. We base our empirical analysis on the World Bank’s Ethiopian Socioeconomic Survey, a panel dataset encompassing nearly 3000 respondents and a Tobit model, based on Difference-in-Difference and the Propensity-Score Matching methods. We find that Ethiopia’s PSNP has a negative impact on farm labour input, both in terms of labour intensity and duration. Furthermore, our results show that participation in the program is associated, on average, with lower on-farm crop diversity. We conclude that the PSNP participation may be crowding-out production stabilizing farming activities, such as intercropping or cover cropping, that are more labour intensive. Our findings call for embedding tools in the new phase of the PSNP (2021–2025) that could incentivise on-farm resilience-oriented investments, in particular leading to higher crop diversification.

Opportunities and Challenges for Cover Cropping in Sustainable Agriculture Systems in Southern Australia

Southern Australian farming systems operate predominantly under Mediterranean climatic conditions, which limit the choice of cover crops suitable for enhancement of ground cover and soil moisture retention, erosion control, atmospheric soil nitrogen (N) fixation, and weed suppression between cash crop rotations. Given that the successful establishment of cover crops is climate-driven and also influenced by edaphic factors such as soil pH and salinity, there has been increased interest by southern Australian producers in identifying potential cover crop species well adapted to specific Australian farming systems, which provide vital ecosystem services and sustainable economic benefits through the improvement of soil properties. This review summarises recent findings on cover crop inclusion in diverse farming systems in southern Australia, including continuous and mixed broadacre cropping as well as viticulture and horticulture systems, to identify opportunities and limitations related to their use. Cover crop inclusion in viticulture and pasture systems with lower moisture stress was observed to benefit the subsequent cash crop through enhanced production potential. Long-term, multi-site field experimentation incorporating summer cover crops in winter crop rotations showed that cover crops enhanced ground cover and soil water infiltration in some locations across southern Australia while sometimes increasing winter crop yield, suggesting that soil type and regional climatic conditions greatly influenced the delivery of multiple cover crop benefits. Collectively, these studies have suggested a need for longer-term field evaluations using multiple cover crop species and investigations of termination options under varying environmental and soil conditions to better quantify the legacy effects of cover crops.

Narrowing maize yield gaps across smallholder farming systems in Zambia: what interventions, where, and for whom?

Maize production in Zambia must increase with a view towards improved food security and reduced food imports whilst avoiding cropland expansion. To achieve this, it is important to understand the causes behind the large maize yield gaps observed in smallholder farming systems across the country. This is the first study providing a yield gap decomposition for maize in Zambia, and combining it with farm typology delineation, to identify the key limiting factors to maize yield gaps across the diversity of farms in the country. The analysis builds upon a nationally representative household survey covering three growing seasons and crop model simulations to benchmark on-farm maize yields and N application rates. Three farm types were delineated, including households for which maize is a marginal crop, households who are net buyers of maize, and households who are market-oriented maize producers. Yield gap closure was about 20% of the water-limited yield, corresponding to an actual yield of 2.4 t ha− 1. Market-oriented maize farms yielded slightly more than the other farm types, yet the drivers of yield variability were largely consistent across farm types. The large yield gap was mostly attributed to the technology yield gap indicating that more efficient production methods are needed to raise maize yields beyond the levels observed in highest yielding fields. Yet, narrowing efficiency and resource yield gaps through improved crop management (i.e., sowing time, plant population, fertilizer inputs, and weed control) could more than double current yields. Creating a conducive environment to increase maize production should focus on the dissemination of technologies that conserve soil moisture in semi-arid areas and improve soil health in humid areas. Recommendations of sustainable intensification practices need to consider profitability, risk, and other non-information constraints to improved crop management and must be geographically targeted to the diversity of farming systems across the country.

Diversified Farming Systems

The paper considers industrial methods of agriculture, as a result of which environmental damage is caused, waterways are polluted, dead zones are created in the oceans, habitat biodiversity is destroyed, toxins are released into the food chain, endangering the health of the population due to outbreaks of diseases and exposure to pesticides. Diversification of the farming system will help to increase the efficiency of resource use, reduce the number of pests and diseases, diversify income sources and increase the sustainability of production.

Environmental impacts and future challenges of livestock sector in Hungary

In developed countries, livestock farming faces significant global challenges, including adverse environmental impacts such as greenhouse gas (GHG) emissions and pollution from industrial animal husbandry. These negative processes were accompanied by the disappearance of livestock breeding from backyards and small farms’ demise in recent decades. As a result, the sector’s significance in rural communities has decreased, causing challenges for rural development. This research investigates these processes on the example of the Hungarian livestock sector from the 1990s to recent years, with statistical and policy document analysis, literature review, and interviews in Hungary’s Southern Great Plain. The results show that the number of animals kept in rural settlements has decreased significantly in the last three decades. The established large-scale industrial animal husbandry is a negative environmental burden without positive externalities. In conclusion, the disappearance of the backyard and small-scale livestock farms from the Hungarian countryside has resulted in the loss of multifunctionality and social exclusion. A diversified farming system and a more balanced policy preference toward civic agriculture and small-scale animal husbandry can bring many environmental, economic, and social benefits to rural Hungary.

Analyzing antifragility among smallholder farmers in Bihar, India: An assessment of farmers’ vulnerability and the strengths of positive deviants

Summary Farmers around the world are increasingly vulnerable: climate variability is identified as the primary stressor, but unfavorable biophysical circumstances and disturbances in the socioeconomic domain (labor dynamics and price volatility) also affect farm management and production. To deal with these disturbances, adaptations are recognized as essential. Antifragility acknowledges that adaptations and volatility are inherent characteristics of complex systems and abandons the idea of returning to the pre-disturbance system state. Instead, antifragility recognizes that disturbances can trigger reorganization, enabling selection and removal of weaker system features and allowing the system to evolve toward a better state. In this study, we assessed the vulnerability of different types of smallholder farms in Bihar, India, and explored the scope for more antifragile farming systems that can ‘bounce back better’ after disturbances. Accumulation of stocks, creation of optionality (i.e., having multiple options for innovation) and strengthening of farmer autonomy were identified as criteria for antifragility. We had focus group discussions with in total 92 farmers and found that most expressed themselves to be vulnerable: they experienced challenges but had limited adaptive capacity to change their situation. They mostly made short-term decisions to cope with or mitigate urgent challenges but did not engage in strategic planning driven by longer-term objectives. Instead, they waited for governmental support to improve their livelihoods. Despite being confronted with similar challenges, four positive deviant farmers showed to be more antifragile: their diverse farming systems were abundant in stocks and optionality, and the farmers were distinguished in terms of their autonomy, competence, and connectedness to peers, the community, and markets. To support antifragility among regular farmers, adaptations at policy level may be required, for example, by shifting from a top-down toward a bottom-up adaptation and innovation regime where initiative and cooperation are encouraged. With a more autonomous orientation, farmers’ intrinsic motivation is expected to increase, enabling transitions at the farm level. In this way, connected systems can be developed which are socioeconomically and biophysically adaptive. When practices, knowledge, and skills are continuously developed, an antifragile system with ample stocks and optionality may evolve over time.

Sustainable Food Supply by Peri-Urban Diversified Farms of the Agri-Food Region of Central Córdoba, Argentina

Peri-urban vegetable cropping areas, such as horticultural farms, provide several ecosystem services, such as the provision of fresh food. However, food supply must be estimated on the basis of the current and potential demand of future populations, taking into account the landscape carrying capacity towards sustainable agricultural planning. From this perspective, the study aimed at estimating the resilience of the “Agri-food Region of Central Córdoba” (ARCC) and its role in supporting the provisioning of ecosystem services, such as proximal services, provided by the diversified agricultural landscape in the peri-urban area of Córdoba (Argentina). A direct field survey has been carried out to collect data on the main species and types of crops, the annual productivity, and the area covered by each species and type of horticultural crops. The data have been statistically elaborated to test the spatial and temporal variability of productivity as well as the spatial autocorrelation. In relation to crop diversification, a total of 30 vegetable species have been recorded in the diversified farms under study, with 15 species identified as the most frequent crops as on the basis of the area dedicated to each vegetable species sampled in the farms (in %). The productivity of 30 species has been integrated into a single value of “vegetable crop productivity mean” (kg/m2), proposed and measured in this study, which has been 3.46 kg/m2. It can be a useful monitoring indicator in diversified production contexts. The estimated food supply (ton/year) of vegetable crops for the 170 farmlands has been 72,881 ton/year. An accurate measurement of the biomass harvested on a given surface area can be useful to assign productivity data to the pixel of each land use/cover class, providing accurate input data for remotely sensed-based models supporting decision-making on food provision in peri-urban systems. In this sense, the paper proposes a methodological framework that can be useful worldwide when up-to-date official productivity data are not available, but they are a necessary basis for planning, decision-making, and the implementation of public policies. Thus, diversity in farming systems can combine high ecological and socio-economic benefits, in terms of ecosystem service provision and sustainable food production.

Farming by the sea: A qualitative-quantitative approach to capture the specific traits of coastal farming in Brittany, France

The forms and presence itself of farming in coastal territories changed profoundly in the 20th century. By contrast with other interface farming systems, such as mountain or peri-urban farming, coastal farming has rarely been studied as such and has not, until now, been considered as a useful category to describe and analyse production systems. The aim of this article is thus to address the relevance of such a categorization, using empirical data collected in Brittany (France) as well as contextual indicators, but also by carrying out a systemic qualitative-quantitative analysis, questioning the forms, depth and continuity of marine influence on farming activities at the local scale. We show that specific traits of coastal farming do indeed exist. A greater diversity of farming systems exists in coastal strip than inland at the regional scale. Four configurations of coastal farming were identified, which result from distinct dynamics and combinations of urbanization and environmental pressures on agriculture. But these specific features cannot be revealed without a comprehensive and historicized approach of its interactions with the coastal zone as a territory, rather than a biophysical milieu. These configurations are characterized in the typical spatial extent of coastal farming and spatial patterns of the transition to inland farming (gradient, discontinuities).

Digital revolution for the agroecological transition of food systems: A responsible research and innovation perspective

CONTEXTSo far, digital technology development in agriculture has mainly dealt with precision agriculture, often associated with conventional large-scale systems. The emergence of digital agriculture - based on the triptych of “new data sources / new processing methods / new inter-connection capacities (internet)” - opens up prospects for mobilizing digital technologies to accelerate the deployment of other forms of agriculture, such as agroecology. A specific research agenda must therefore be built to redirect researchers specialized in digital technologies towards these new issues. This construction is significant because digital technology and agroecology are disruptive innovations that shake up the actors' practices, agricultural innovation ecosystems, and value chains. OBJECTIVEAn interdisciplinary group of INRAE researchers (covering 10 scientific departments) was mandated to carry out this reflection, with the objective of developing a research agenda to better couple digitalization and agroecology, in order to pave the way for responsible digital farming. The group used the framework of responsible research and innovation. METHODOver 18 months, the group met monthly by video-conference, to overcome the interdisciplinarity barrier, and at three face-to-face seminars, where creative design exercises were carried out (based on a world café format, and “remember the future” method). This work gave rise to three prospective lines of research aimed at putting digitalization at the service of agroecology and local food systems. These topics prioritize research that fosters innovations in digital technology, as well as organisations and policies that (1) accelerate the agroecological transition on the farm and in the territories, (2) manage the territories as commons, (3) empower farmers and consumers. Then, the group examined these three prospective lines of research from an RRI perspective as well as three current research topics on digital agriculture (digital soil mapping, precision agriculture, technologies for food wastage reduction). RESULTS AND CONCLUSIONSThis work allowed us to highlight the gaps between current research on digital agriculture and the RRI expectations, and the tensions (between rationalization and diversity of farming systems, between complexity of agroecological systems and the need for simplification of models, and finally between data speculation and frugality). We were also able to refine the specific scientific questions of each prospective line of research and finally to draw attention to the key levers that will have to be integrated if these research efforts are to be approached from an RRI perspective. SIGNIFICANCEThis contribution shows RRI can be used not only to reflect on research practices but also as a framework to build a research agenda paving the way for responsible digital agriculture.

Diversité des exploitations laitières sous indication géographique en Savoies : vers une fragilisation des filières ?

Cet article propose d’étudier la diversité des pratiques d’élevage dans les filières fromagères sous indication géographique (IG), au regard des nouveaux enjeux socioéconomiques et environnementaux auxquelles elles sont confrontées. Huit filières ont été étudiées en Savoie et Haute-Savoie, à l’aide d’entretiens semi-directifs auprès de 24 éleveurs. Grâce à la réalisation d’une typologie, les résultats montrent que leurs stratégies d’exploitation sont influencées par deux éléments principaux qui sont le désir de dégager du temps libre et l’importance de leur identité professionnelle. L’ampleur de cette diversité et la tendance à l’intensification mises en avant questionnent l’évolution des cahiers des charges et les stratégies à venir des filières.

Monoculture, crop rotation policy, and fire

Monoculture farming pollutes the environment by increasing the use of inputs, accelerating soil erosion, polluting water resources, raising carbon level in the atmosphere, and decreasing biodiversity. Therefore, farmers are advised to implement diversified farming systems such as crop rotation. However, crop rotation, i.e., planting more than one crop in the same field over a given year, may also harm the environment. To combat the environmental problems of monoculture, Turkey announced to implement a new crop rotation policy in 2020. The government said it would not provide support payments if farmers planted the same crop in the same plot for three consecutive years. This paper estimates the impact of this crop rotation policy on monoculture and shows how agricultural fires changed with this policy. We find that Turkey's crop rotation policy significantly decreased monoculture practices. Farmers decreased their cotton acreages and replaced cotton with wheat as the primary and corn as the secondary crop. However, since farmers burn their fields after the primary crop is harvested, the number of fires tripled after the policy. This environmentally friendly policy unexpectedly polluted the environment. Our paper shows how policies may create unintended environmental problems if they do not consider farmers' behavioral constraints.

Financial profitability of diversified farming systems: A global meta-analysis

Diversified farming systems are promoted as a pathway to more sustainable agricultural production. Yet widescale adoption may be slow because of uncertainty about the viability of farmer livelihoods on diversified farms and entrenched perceptions that monocultures are key to making farming profitable. Here, a global meta-analysis of 3192 effect sizes from 119 peer-reviewed articles provides evidence that diversified farming systems are at least as profitable as simplified farming systems. Our study showed that, on average, total costs, gross income and profits (net income, or gross margin) were higher in diversified systems relative to simplified ones, while the benefit-cost ratio was equivalent. These results held in developed and developing countries and across geographic regions. From a subset of 43 articles reporting labour inputs, we found that labour costs increased in diversified farming systems, but so did gross incomes leading to farm profits equivalent to those in simplified systems and dispelling myths that higher labour requirements undermine the viability of diversification. Our global meta-analysis provides compelling evidence that diversified farming systems are not only viable but actually economically preferable to simplified systems in the wide range of contexts represented in this study. Policies, markets, investments, and value chains need to align with this evidence and promote diversified farming systems for the benefit of farmers and rural economies.

Organic farmers face persistent barriers to adopting diversification practices in California’s Central Coast

ABSTRACT In the face of myriad environmental challenges associated with industrial agriculture, some farmers and researchers have looked to diversified farming systems as a promising alternative. Despite well-documented ecological benefits, diversification practices remain rare in many regions of the U.S, even amongst organic farmers. Our study focuses on organic farmers in the Central Coast region of California, an area that has played a crucial role in the rise of organic agriculture over the last several decades. Through 20 interviews with farmers who all grow lettuce and 8 interviews with technical assistance providers, we investigate the persistent barriers that growers in this region face in adopting diversification practices including cover cropping, compost application, crop rotation, insectary strips, and hedgerows. We find that high land rents, the predominance of short-term leases, stringent food safety standards, and other supply chain pressures significantly hamper the adoption of diversification practices. In order to surmount these barriers and increase adoption, solutions must be pursued at three interconnected levels: innovation at the farm level, and policy change at the technical and structural levels. Locally-informed, integrated, and innovative policies across these three levels must be explored to support the creation of a more resilient, sustainable, and equitable food system.

Positive deviant strategies implemented by organic multi-species livestock farms in Europe

CONTEXTTransitions to more sustainable livestock production systems are increasingly demanded by parts of society. Scientists suggest moving towards diversified farming systems due to their potential environmental and economic benefits, especially in the organic sector. However, empirical knowledge of multi-species livestock farms, i.e. farms keeping two or more animal species, is lacking. OBJECTIVEOur objectives were to identify European organic multi-species livestock farms that outperform their peers despite having the same resources and constraints, and characterize their distinctive management principles. METHODSWe conducted surveys on 102 farms in seven European countries: Austria, Belgium, France, Germany, Italy, Sweden and Switzerland. We restricted the analysis to a sub-sample of 75 farms that had complete data and that covered 3 main livestock combinations (cattle and sheep, cattle and pigs, cattle and poultry) with similar number of farms. We implemented a positive deviant approach based on three indicators: land productivity, nitrogen input dependence and satisfaction regarding income. RESULTS AND CONCLUSIONSFive structurally diverse positive deviant farms were identified with 4 types of livestock combinations represented, and farmland area ranging from 25 to 273 ha, herd size from 33 to 146 livestock units (LU) and total workforce size from 1 to 24 annual worker units (AWU). These farms were located on a trade-off between land productivity and autonomy for feed, and all but one had high overall autonomy for feed (89–100% against a mean of 76% for the whole sample). Their diversity of pastures, crops and livestock species and their diversification beyond agricultural production were controlled (e.g. no agritourism) and below that of the other sample farms, to remain manageable by the farmers while still allowing to buffer shocks and hazards. Interactions among farm enterprises remained limited to matter (mainly grain, straw, hay, manure) flows, and practices requiring specific efforts and investments (e.g. for fencing), such as co-grazing of different livestock and crop residues grazing, were avoided. SIGNIFICANCEWe conducted the first integrated study on European organic multi-species livestock farms and identified key management principles implemented on positive deviant farms. We showed that whatever their size, farms outperforming their peers do not necessarily maximize diversity of agricultural productions and of non-agricultural activities, and interactions among farm enterprises but that they remain at a level of complexity manageable by the farmers. These principles will inform farmers running multi-species livestock farms or transitioning to this model.

Diversified Farming Systems: Impacts and Adaptive Responses to the COVID-19 Pandemic in the United States, Norway and China

The COVID-19 pandemic fully exposed the vulnerability of the global agri-food system to shocks and stresses, highlighting the need for transformation and action to make it more resilient and inclusive. This paper offers a unique insight into the global nature of the COVID-19 pandemic by examining impacts and responses in the agri-food sector within three very distinct contexts, namely the United States, Norway, and China. Focusing on small, diversified farms, the study builds on prior research with the same farmers and support organizations from an on-going collaboration. Firstly, we conducted a short review of policy adaptations to understand how governments, the private sector, non-profit organizations, and communities “stepped up” to provide emergency relief, specialized training, and recovery support for farmers, support that was instrumental in preventing more devastating impacts in all three countries. Secondly, drawing from in-depth interviews with farmers (23) and government and non-governmental support organizations (19), we mapped the vulnerability and resiliency of selected farmers to shocks that severely disrupted traditional supply chains during the COVID-19 pandemic. Data were collected on both the negative and positive impacts of the pandemic to farmer inputs, including labor, operations, and markets, how these changed from the initial lockdowns in early 2020 and through 2021, and on farmer adaptive responses to these impacts. In some contexts, innovation and adaptive responses counteracted negative impacts. We saw diversifying markets, catering to consumer safety concerns, switching to direct and e-markets, hiring in more labor or relying on family labor, and switching to high demand crops and products as the most prominent adaptive responses. Farmers who lacked access to information and government programs, in large part because of language, technology and institutional barriers, missed out on pandemic related opportunities and suffered the most. As we enter the post-pandemic new normal it is important to take stock of lessons learned, and to continue to support those initiatives and innovations that were pivotal not only for weathering the storm, but for building a more inclusive and resilient agri-food system in the long-run.

Niche complementarity drives increases in pollinator functional diversity in diversified agroforestry systems

Rising demand for food production poses a major threat to biodiversity by placing competing pressures on land. Diversified farming systems are one widely promoted nature-based solution to this challenge, which aim to integrate biodiversity-based ecosystem services into agricultural production. The underlying theory behind this approach is that diverse communities enhance ecosystem service provision, although the evidence to support this theory is often inconsistent for reasons that are not always clear. Here we investigate the contribution of pollinators to ecosystem function in a model example of a diversified farming system, silvoarable agroforestry comprising apple trees intercropped within arable fields. We assess pollinator species richness, species diversity, and functional trait diversity, between agroforestry fields and paired monoculture arable controls, and within agroforestry fields at set distances from tree rows, to quantify their potential contributions to pollination service. Species richness and diversity, and functional richness and dispersion, of wild bees were found to be significantly higher in agroforestry systems, despite weak effects on mean trait values. No significant effects were found for hoverflies. Supplemental bee species found in agroforestry systems were shown to increase functional diversity primarily by enhancing niche complementarity, effectively filling in gaps in niche space for traits, which could be partly attributed to a higher abundance and diversity of floral resources in the associated understorey. Nationally rarer bee species also contributed substantially to functional richness but not consistently to functional dispersion, suggesting that while they provide a unique functional role, their contributions to ecosystem services remain limited by low local abundances. These mechanistic insights reveal how the relationship between biodiversity and ecosystem functioning can be influenced by farm management practices through their effect on the spatial and temporal availability of habitat resources.

Natural Farming - A Sustainable Ecological Approach

Natural Farming is a chemical free traditional agro-ecology based diversified farming system which integrates crops, trees and livestock with functional biodiversity. Natural farming increases production, saves water, improves soil health and farmland ecosystems. It is considered as a cost effective farming practices with scope for raising employment and rural development. Types on natural farming includes Fertility farming, Organic Farming, Sustainable agriculture, Agro-ecology, Agroforestry, Ecoagriculture and Permaculture rely on principles of no tillage, no fertilizer, no pesticides or herbicides, no weeding and no pruning depending upon local climate and conditions.

Progress in research on site-specific nutrient management for smallholder farmers in sub-Saharan Africa.

Increasing fertilizer access and use is an essential component for improving crop production and food security in sub-Saharan Africa (SSA). However, given the heterogeneous nature of smallholder farms, fertilizer application needs to be tailored to specific farming conditions to increase yield, profitability, and nutrient use efficiency. The site-specific nutrient management (SSNM) approach initially developed in the 1990 s for generating field-specific fertilizer recommendations for rice in Asia, has also been introduced to rice, maize and cassava cropping systems in SSA. The SSNM approach has been shown to increase yield, profitability, and nutrient use efficiency. Yield gains of rice and maize with SSNM in SSA were on average 24% and 69% when compared to the farmer practice, respectively, or 11% and 4% when compared to local blanket fertilizer recommendations. However, there is need for more extensive field evaluation to quantify the broader benefits of the SSNM approach in diverse farming systems and environments. Especially for rice, the SSNM approach should be expanded to rainfed systems, which are dominant in SSA and further developed to take into account soil texture and soil water availability. Digital decision support tools such as RiceAdvice and Nutrient Expert can enable wider dissemination of locally relevant SSNM recommendations to reach large numbers of farmers at scale. One of the major limitations of the currently available SSNM decision support tools is the requirement of acquiring a significant amount of farm-specific information needed to formulate SSNM recommendations. The scaling potential of SSNM will be greatly enhanced by integration with other agronomic advisory platforms and seamless integration of digital soil, climate and crop information to improve predictions of SSNM recommendations with reduced need for on-farm data collection. Uncertainty should also be included in future solutions, primarily to also better account for varying prices and economic outcomes.

Landscape complexity and functional groups moderate the effect of diversified farming on biodiversity: A global meta-analysis

Homogenisation and intensification of agricultural ecosystems are among the most important threats to biodiversity, linked to declines in pollinators, soil biota and ecosystem functioning. Diversification has been proposed as a way to restore ecosystem functioning in agricultural landscapes. To manage agricultural land for multiple ecosystem functions, evidence is needed of the effect of diversification on functionally distinct taxa. We contribute to closing this knowledge gap through a global meta-analysis of 161 peer-reviewed articles addressing the abundance and richness of six distinct functional groups: autotrophs, decomposers, natural enemies, pests, pollinators, and other. We found diversified farming systems increased overall species richness by 26% on average, relative to simplified farming systems. However, the effect of diversified farming on the overall mean abundance was weak. Our study shows diversified farming systems enhanced the abundance and richness of beneficial species while reducing the abundance of pests (e.g., weeds, herbivores), thus providing benefits for both agricultural production and biodiversity. The positive effect of diversified farming systems on the overall mean species richness was stronger in farms in more simplified landscapes, i.e., those that are further from natural and semi-natural habitats or have a lower proportion of seminatural vegetation in a 1 km radius. Pollinator’s abundance and richness were highest in diversified farming plots located far away from natural and semi-natural habitats. In contrast, proximity to these natural and semi-natural habitats (<250 m) increased the positive effect of diversified farming systems on natural enemies’ abundance, while reducing the number of pests. Our results add to the body of evidence calling for the repurposing of policies, regulations, and international agendas to promote, support and incentivize the adoption of diversified farming practices for supporting biodiversity. Spatial planning of diversification schemes should consider the landscape context of farms to ensure the greatest benefit of intervention.
