Lively commodities and endemic diseases: Shifting commodity situations and nonhuman disability in cattle and sheep on UK farms

The concept of ‘lively commodities’ captures how aspects of the life of certain entities affect their commodification and exchange within capitalist economic systems. Their status as being, or comprised of, living things matters to their commodification in different ways in particular places and spaces and at particular times. This paper uses the empirical example of diseased farmed animals in the north of England to examine the effects of susceptibility to disease on the process of lively commodification, drawing on conceptualisations of nonhuman disability and relations of care alongside literature on lively commodities, and exploring cases of multi-lifeform co-production of disease. It thus focuses on moments where the liveliness of animals means that commodification ‘goes wrong’, because liveliness means susceptibility to injury and disease, alongside its potential for economic production. The paper focuses on two important endemic conditions affecting UK farming: lameness in cattle and sheep, and bovine viral diarrhoea (BVD) in cattle. These conditions significantly affect animals' welfare and impact on farm productivity. Drawing on qualitative analysis of transcripts from in-depth interviews with 29 farmers and 21 farm advisers (e.g. vets), the paper examines three empirical themes where farming practices are strongly affected by the lively nature of the commodities being produced: first, the anticipatory practice of breeding animals resistant or vulnerable to disease; second, lameness and nonhuman disability; and third, BVD and threats to agricultural biosecurity. The paper concludes by revisiting the concept of lively commodities in situations where farmed animals are diseased, and reflects on the implications of this for their shifting commodity status in particular times and places.

Who can predict farmers’ choices in risky gambles?

Abstract Risk is a pervasive factor in agriculture and a subject of great interest to agricultural economists. However, there is a lack of comprehensive understanding of the knowledge held by farm advisors, students, and economists with regards to farmers’ risk preferences. Misconceptions about farmers’ willingness to take risks could lead to misguided advice. This study builds upon a recent multinational endeavor that employed a multiple price list to assess risk preferences among European farmers. We expand this research by gathering predictions for farmers’ risk preferences from 561 farm advisors, students, and economists. Our objectives are threefold: firstly, we explore variations as to how accurately participants can predict risk preferences in different specializations; secondly, we compare the predictive accuracy of different groups of forecasters; and thirdly, we assess whether modifying incentive mechanisms can improve the accuracy of predictions. Whereas our findings reveal substantial variation in individual predictions, the averages closely align with the observed responses of farmers. Notably, the most accurate predictions were provided by a sample of experimental economics researchers. Furthermore,predictions for different production systems exhibit minimal disparities. Introducing incentive schemes, such as a tournament structure, where the best prediction receives a reward, or a high-accuracy system, where randomly selected participants are compensated for the accuracy of their predictions, does not significantly impact accuracy. Further research and exploration are needed to identify the most reliable sources of advice for farmers.

Telling Tales: Using Vignettes to Overcome Optimism Bias in Farm Health and Safety Attitudinal Studies

ABSTRACT Objective Measuring attitudes of farmers to safe farming practices using quantitative causal relationship approaches is central to improving understanding of (un)safe practices. This knowledge is important in the development of effective farm safety interventions. However, the accuracy of quantitative attitudinal studies in explaining farmers’ decision-making faces a potential measurement challenge, i.e. a high level of optimism bias. In this paper, we present research that develops and tests farm safety attitudinal questions that are framed around “real-life” farming practices with the objective of reducing optimism bias. Methods We apply construal level theory (CLT) to support the design of vignettes that reflect common risk scenarios faced by farmers. Applying qualitative analysis of 274 fatal farm incidents that occurred in Ireland between 2004 and 2018 we identify the occupational behaviors (what farmers do), social (who are farmers), spatial (where farming takes place), and temporal (when farming happens) dimensions of risks resulting in most deaths. The results informed subsequent co-design activities with farm safety experts and farm advisors to develop “real-life” scenarios, attitudinal questions, and response options. The questionnaire was piloted and subsequently implemented to collect data from a sample of 381 farmers with either tractors or livestock. The results of the survey were compared to previous attitudinal research on farmer’s attitudes to safety in Ireland to establish if there was as follows: i) increased variance in the responses, and ii) a statistically significant difference in the attitudes of respondents compared to the results reported in previous studies. Results The findings established that when farmers were provided with real-life scenarios, their responses were less optimistic and more varied, i.e. there was a greater range of responses, compared to previous studies. Conclusion Applying CTL to the development of attitudinal survey instruments anchors attitudinal questions within farming specific occupational, social, spatial, and temporal contexts. The use of vignettes that draw on real-life scenarios offers the potential for improved design of surveys that seek to understand farmer/worker practices. The results suggest that this approach can improve the measurement of attitudes to farm safety.

Human resource management practices on Irish dairy farms: an exploratory study

Context Managing people outside the farm family unit is a new issue for many Irish dairy farmers. In the context of rapid growth, the demand for employees has increased, creating the need for Irish dairy farmers to have human resource management (HRM) skills. Aims This paper explores the extent and type of HRM practices adopted by Irish dairy farmers and the factors that influence their adoption. Methods A questionnaire was developed, piloted, and issued to farmers on the basis of herd size and location. Data from 203 dairy farmers who employ people were analysed to examine the adoption of different HRM practices and the influence of farm characteristics, farmer demographics and farmer attitudes on their adoption. HRM practices included compliance with employment legislation, health and safety, different approaches to recruitment, workforce management and retention. The questionnaire included one or more variables for each of these HRM practices. Where more than one variable was included, an aggregate variable was developed for that practice. Key results Whereas, overall, there was a low level of adoption of best HRM practices, farm characteristics such as herd size and number of employees had a significant influence on farmers’ adoption of compliance with employment legislation, health and safety, recruitment, workforce management and retention practices. Demographic factors such as age, level of education, and average hours worked influenced farmers compliance with employment law legislation, workforce management practices and retention practices. Conclusions The study highlighted an overall low compliance with employment legislation and low adoption of best practices in managing staff among dairy farmers in Ireland. Implications This study highlighted that improvement is needed in all areas of HRM on Irish dairy farms. The findings of this study would be useful to farm advisors who support dairy farmers in improving their management of their businesses. Overall, this study has contributed to a greater understanding of the challenges in managing people in agriculture and how certain factors influences the adoption of HRM practices on dairy farms.

Strengthening the role of innovation brokers in the livestock advisory services system of Pakistan

Context This article assesses development and implementation of a non-traditional training ‘whole-family extension approach’ (WFEA) that contributes to the innovation-brokering capacity of farm advisors within the current livestock advisory services system of Pakistan. Aims The primary objectives of the research were to explore how the WFEA training leads to improved capacity and knowledge of farm advisors and then examine these through the lens of innovation brokers and the difference they can make within the extension system, including (1) articulation of problems and possibilities, (2) network building and (3) supporting negotiation and learning in networks. Methods A qualitative investigation was conducted during four facilitated discussions and three field follow-up visits following project interventions to build the capacity of 50 farm advisors from across a network of 22 organisations that are part of the Pakistani’s livestock extension system. Data were collected by using the following two qualitative approaches: (1) facilitated discussions, during each of the four separate training workshops; and (2) field follow-up visits, where farm advisors were interviewed following a set of semi-structured questions. The data were analysed to assess the changes observed across the different farm advisors during the training interventions and subsequent mentoring provided by the project team. Key results Gaps in innovation-brokering capacity from WFEA were identified and include co-designing and more institutional support of various collaborating organisations, use of visioning tools, scenario analysis to predict possible future for the farm-advisor training and training of farm advisors on analytical skills to capture the household impacts; these should be incorporated in WFEA training. Conclusions A holistic extension training intervention approach (the WFEA) can positively influence the innovation-brokering capacity of farm advisors within the current livestock advisory services system of Pakistan. Implications This article has contributed to the literature on innovation-brokering roles in the livestock advisory systems by highlighting key additional functions of innovation-brokering in a developing-country context. Furthermore, examples from Pakistan can be used to show how farm advisors can develop skills in articulating problems and possibilities, network building and supporting negotiation and learning in networks.

Using a perception matrix to elicit farmers‘ perceptions towards stakeholders in the context of biodiversity-friendly farming

Farmers' pro-environmental action is substantially influenced by various stakeholders from their business and social environment. Recent studies recommend actively involving influential stakeholders in agri-environmental initiatives, information or media campaigns. While it has been argued that farmers' perceptions towards these stakeholders can help inform effective involvement, comprehensive assessments of these perceptions remain scarce, particularly in the context of biodiversity-friendly farming. To understand and compare farmers’ perceptions of these stakeholder quantitatively, we developed and applied a perception matrix. In an exploratory survey with 49 farmers across ten European countries, farmers rated twelve groups of stakeholders (e.g. government bodies, farm advisors and input suppliers) against eight perception constructs (e.g. trustworthiness, interest in protecting biodiversity). We found that perceptions differed significantly both between groups of stakeholders and between constructs. Whereas several stakeholders were, on average, perceived positively regarding their general characteristics, such as trustworthiness, reliability, understanding and support for farming, perceptions regarding their biodiversity-related behavior were significantly more negative. Our findings indicate potential to improve policy development and implementation of agri-environmental initiatives through the involvement of multiple, non-governmental, agricultural and non-agricultural stakeholders in biodiversity-friendly farming initiatives across the entire agri-food value chain. Such multi-stakeholder initiatives could help to not only reinforce biodiversity conservation action among the farming community, but across society as a whole as emphasized by the Convention on Biological Diversity. Further research is needed to confirm the observed trends on a larger, representative sample, for which the presented perception matrix is well suited.

Making a mark on the farm: the marks and traces of farm animals and infectious diseases in northern England

ABSTRACT Farmed animals are expected to move through farmed spaces in certain ways to maximise their productivity. These spaces are also designed to limit the movement of disease-causing organisms. However, both types of lifeforms do not always move in expected ways. We focus on the mark-making of these organisms to explore: 1) the evidence of their movements through farm spaces; and 2) the effects of these movements on managing farm animal disease. We explore these questions via social-scientific and artistic practices. The social science draws on in-depth interviews with UK cattle and sheep farmers, and farm advisors. The artistic component draws on work conducted by an ‘artist in residence' engaging with farm animals and farmer-livestock relationships. Farm animals and infectious micro-organisms were found to move in different ways and create different marks and traces across farms, bodies, and how diseases were managed. These lifeforms often frustrated biosecurity practices of exclusion and enclosure and existed on a spectrum of disease risk. Human actors needed to learn to become attuned to lifeform movements in order to enact disease management. We conclude by suggesting a continued focus in future social-scientific research on how the ‘sub-animal body' contributes to the enacting of farm disease management.

From values to actions in agriculture: A web of actors shape Norwegian farmers' enactment of relational values

Abstract A sustainable transition in the agri‐food system holds society‐wide implications. Farmers play central roles in responding to climate change, environmental degradation and sustainable food production. Still, factors underlying how farmers make decisions and manage their farms are often marginalised in efforts to develop policies to tackle these issues. The concept of relational values, defined as preferences, principles and virtues based on human–nature relationships, recently emerged to expand understandings of environmental decision‐making in general and that of farmers specifically. As agricultural landscapes are dynamic and characterised by the interaction of various actors with diverse values and interests, how these interactions influence farmers' decisions remains underexplored. This paper engages with these issues by using qualitative data on Norwegian horticultural farmers' motivations, opportunities and challenges in farming. We find that their relational values (a) are influential in shaping farmers' decisions about farm management and (b) are continually unfolding and embedded within a web of other actors, including grocers, retailers, consumers, farm advisors and policymakers, which shapes farmers' enactment of their relational values. In the context of agriculture, this research underlines the utility of an in‐depth understanding of relational values as embedded in wider social systems to enrich analyses of farmer decision‐making. How farmers' relational values are shaped and realised through interactions with other actors holds important implications for policy and programming to navigate tensions between different interests and actors for sustainable and long‐term change.

How much do conservation cropping practices mitigate runoff and soil erosion under Western European conditions: A focus on conservation tillage, tied ridging and winter cover crops

AbstractConservation farming practices are known for their capacity to mitigate runoff and erosion, but the magnitude of their effectiveness is highly variable across studies. In order to better understand the contribution of environmental and management factors to their effectiveness, up to 37 studies reporting 271 individual trials were collated for a quantitative review regarding 3 common conservation agriculture‐related practices, at the plot scale and in a Western European context. Two different methods suitable for hierarchically structured data sets were used for the meta‐analyses—hierarchical nonparametric bootstrapping and linear random effects models—, yielding nearly identical average outcomes but differing in terms of confidence intervals. We found that, on average, winter cover crops reduce cumulative seasonal (autumn‐winter) runoff by 68% and soil losses by 72% compared with a bare soil. The occurrence and intensity of stubble tillage on the control plot is a key explanatory variable for the mitigation effect of winter cover crops. In potato crops, tied ridging reduces cumulative seasonal (spring–summer) runoff by a mean of 70% and soil erosion by 92%. Conservation (non‐inversion) tillage techniques alleviate cumulative seasonal overland flow by 27% and associated sediments losses by 66%, but strong evidence of publication bias was detected for this farming practice, probably leading to an overestimation of its effectiveness. These mitigation effects are shown to be much greater for spring crops than for winter crops, and to increase with time since ploughing was stopped. The type of conservation tillage scheme strongly affects the ability to attenuate surface flows. Intensive non‐inversion tillage systems relying on repeated use of (powered) tillage operations appear to be the least effective for reducing both water and sediment losses. The best performing scheme against runoff would be a deep (non‐inversion) tillage (−61%), while against erosion it would be a no‐till system (−82%). Although several explanatory factors were identified, there remains a high (unexplained) variability between trials effect sizes, thus not attributable to pure sampling variability. Meanwhile, this review provides farm advisors or policy makers with guidance on the contexts in which implementation of such conservation practices should be supported so as to maximize expected benefits.

Farm advisors’ perspectives on barriers and opportunities for wetland creation – the view from Sweden

Farm advisors are important knowledge transfer agents for improving rural sustainability. Most literature focuses on their role in improving farm economies, but they can also promote greater environmental sustainability. Across Europe, most natural wetlands have been drained, impacting multiple ecosystem services (ES) including biodiversity support and nutrient retention, highlighting the need for increased restoration and creation efforts. In Sweden, these efforts depend on voluntary landowner actions. We interviewed farm advisors to learn how they encourage landowners to create and manage wetlands and the institutional barriers they still encounter. Advisors highlighted trust and long-term relationships as key success factors and considering landowner motivations that often prioritize recreational and cultural ES. Advisors noted overly complex bureaucracy, breaks in funding, inadequate long-term support, and lack of holistic perspectives as barriers for wetland creation. These insights about successful advisor/landowner interactions for wetland creation can be applied when implementing other agri-environmental measures.

Using microbial biocontrol for disease control in French vegetable production: An analysis of the perspectives of farmers and farm advisors

Microbial biocontrol products are increasingly available as alternative solutions to chemical control for the management of vegetable diseases. However, their use is still limited. A study was carried out to analyse this situation and identify the needs and limits encountered by users of biocontrol agents, with the goal of suggesting potential ways of improvement. A survey of French vegetable farmers and farm advisors was therefore conducted. First, online questionnaires were disseminated to more than 500 professionals, with queries on their use of biocontrol products, targeted diseases, and perceived efficacy. In a second step, face-to-face interviews were performed with 42 of the 217 respondents, to obtain in-depth technical information about successes and difficulties encountered by users in the implementation of biocontrol. The answers to the online questionnaires highlighted that only few biocontrol products were known and used, and their efficacy was perceived as low by users. This diagnosis was confirmed by the face-to-face interviews. While users showed awareness of the benefits of applying biocontrol products to manage plant diseases, they also reported that unstable efficacy, together with difficulties in using biocontrol along with other cultural practices, resulted in questionable interest. More than 85 % of the users expressed the need for additional technical benchmarks on the efficacy of marketed biocontrol products and for practical guidelines helping to choose the most adequate products for specific situations and to obtain information about the most efficient way to use biocontrol solution. Propositions are made to address the needs of users and to foster a wider use of microbial biocontrol agents in vegetable crops.

Stochastic modelling of pesticide transport to drinking water sources via runoff and resulting human health risk assessment

A modelling framework was developed to facilitate a probabilistic assessment of health risks posed by pesticide exposure via drinking water due to runoff, with the inclusion of influential site conditions and in-stream processes. A Monte-Carlo based approach was utilised to account for the inherent variability in pesticide and population properties, as well as site and climatic conditions. The framework presented in this study was developed with an ability to integrate different data sources and adapt the model for various scenarios and locations to meet the users' needs. The results from this model can be used by farm advisors and catchment managers to identify lower risk pesticides for use for given soil and site conditions and implement risk mitigation measures to protect water resources. Pesticide concentrations in surface water, and their risk of regulatory threshold exceedances, were simulated for fifteen pesticides in an Irish case study. The predicted concentrations in surface water were then used to quantify the level of health risk posed to Irish adults and children. The analysis indicated that herbicides triclopyr and MCPA occur in the greatest concentrations in surface water, while mecoprop was associated with the highest potential for health risks. The study found that the modelled pesticides posed little risk to human health under current application patterns and climatic conditions in Ireland using international acceptable intake values. A sensitivity study conducted examined the impact seasonal conditions, timing of application, and instream processes, have on the transport of pesticides to drinking water.

Exploring farmer and advisor lameness management behaviors using the COM-B model of behavior change.

This paper applies the COM-B framework to farmer and farm advisor understandings and responses to lameness in sheep, beef, and dairy systems. It reflects on how farmers' and advisors' capability, opportunity, and motivation (COM-B) influence lameness management practices in these farming systems, and considers the interaction between these three factors, and stakeholders' behavior. Interviews with 29 farmers and 21 farm advisors in the north of England were conducted. Thematic analysis was undertaken with results categorized in relation to the COM-B framework focusing on barriers and enablers of lameness management. Use of the COM-B model provides a useful means of understanding the underlying behavioral mechanisms that contribute toward the persistence of lameness. This includes the complexities and interactions which hamper implementation of lameness management best practice. The findings highlight three key areas to address with interventions to improve lameness management on farm: (1) removing physical and social barriers for lameness management; (2) improving psychological capability and motivation for lameness management; and (3) facilitating relationships and developing communication between farmers and advisors. In particular, the value of exploring both farmer and advisor perspectives on behavior in the animal health context is demonstrated. Future interventions should look to target these three areas to overcome barriers and focus on factors that enable positive lameness practices to occur.

The everyday work of farm advisors as interface bureaucrats in greening French agricultural policies

For the last three decades, public agricultural policies in France and in Europe have progressively integrated environmental objectives through a wide range of instruments. Whereas a large body of research has examined the extent to which the greening of agricultural policies has shaped farmers' decisions and practices, few studies have considered how these normative policy orientations may trigger tensions within the agricultural bureaucratic apparatus, and notably among local farm advisors who play the role of interface bureaucrats. In this article, we have explored how farm advisors from different types of advisory structures develop multiple subjectivities and deal with the tensions that they face when navigating between policy goals, professional norms, and their personal beliefs and values. Drawing on plural qualitative methods, we focus on the implementation of two national public agroecological schemes in southwest France that support the emergence and facilitation of farmers' groups engaged towards agroecology. We find that organizational strategies shape the type of tensions advisors face and their ability to manage these. The type of policy instrument we considered also matters in the forms of creative bricolage that farm advisors develop: in the case of organizational instruments based on farmers' participation, maintaining relationships with farmers is critical to give meaning to their work. If such instruments enlarge the creative space of farm advisors, the schemes we examined also hold in-built limitations in empowering farm advisors as they fail to address the structural constraints that shape agroecological transitions.

Experts’ opinion on the sustainable use of nematicides in Mediterranean intensive horticulture

Aim of study: Root-knot nematodes are considered a common limiting factor to reaching premium quality and economically viable yields in horticultural crops. Soil disinfestation with agrochemical fumigants has been the main nematode control method until their recent ban due to environmental and social concerns. This paper explores farmers and agricultural advisors’ opinion and preferences on the sustainable use of available nematode control methods, considering sustainability as an integration of nematicidal effectiveness, reduction of environmental harmful effects and preservation of human health. Area of study: This study has been carried out between farm advisors of intensive horticultural crop areas in Southern Spain. Material and methods: Farm advisors’ opinion and preferences on the use of nematicides was evaluated following an opinion survey and the Analytic Hierarchy Process (AHP) method. The analysis done was exploratory. Main results: Providing that current available control methods give enough nematicidal effectiveness to get a profitable yield, the group of farm advisors showed a great consciousness on the use of sustainable alternatives for nematode control in intensive horticultural crops, prioritizing biosolarization as the first option, followed by biopesticides and fumigant nematicides in third place. The use of ozone and non-fumigant nematicides with high toxicity profiles were considered the last options, but new generation nematicides with lower ecotoxicity profiles are also considered as an important tool in sustainable nematode management. Research highlights: These results provide a prediction of farmers' responses to the sustainable use of nematicides promoted by the European Union when agrochemical fumigants are banned.

Competencies Needed for Guiding the Digital Transition of Agriculture: Are Future Advisors Well-Equipped?

As the penetration of digital technologies in agriculture deepens, farm advisors have to cope with new roles, which generate the need for updating already possessed and developing new competencies. Although in-service advisors can build such skills through their involvement with the practice of digital agriculture, students of agronomy (and related) departments who will undertake the role of advisors in the future are expected to develop relevant competencies during their university education. Do current curricula supply them with such competencies? In pursuing this question, in the present study, we developed a theoretical scheme involving eight sets of competencies. After constructing a scale for each set, we collected data from students enrolled in an agronomy department of a Greek university. Our findings revealed that participants’ overall competency in dealing with digital agriculture was considerably low. Among the eight sets of competencies, the highest scores were observed for empathy and future orientation, while students had low levels of technology exploitation, technology integration, and transition facilitation competencies. A regression analysis indicated that the two last sets shape students’ overall competency. These results point out the need to integrate a farmer-centered philosophy in digitalization-related higher agronomic education and consider the critical role that social science can play in equipping future advisors with competencies needed to facilitate the digital agricultural transition.

321 Rancher Motivations for Joining Sustainability Programs

Abstract Livestock’s environmental footprint has become a pivotal concern for both consumers and investment corporations. To stay competitive in the sustainable foods movement, the beef industry has sought to improve sustainability within their own supply chains. However, before system sustainability can be achieved, more sustainability practices must be adopted and implemented by the foundation of the system. Therefore, to gain insight into motivations of ranchers for adopting new sustainable practices we administered an online multi-state survey to cattle ranchers in collaboration with state Cattlemen’s Associations. In total, the survey consisted of 45 questions and was divided into four sections including: 1) rancher demographics, 2) ranching educational resources, 3) current best management practices, and 4) willingness to join new rancher sustainability program. Of the survey participants (n = 884), when asked what made them trust/ believe in a ranching educational program, 64% of ranchers stated they trusted (very or extremely) science, 55% or ranchers stated they trusted a ranching educational program if the program was partnered with state cattlemen’s associations, and 32% of ranchers stated they trusted the program if other ranchers they knew were currently enrolled in the program. When survey participants were asked who they trusted most to dispense ranching educational information 79% trusted veterinarians (very or extremely), 63% trusted extension agents/ farm advisors, 57% trusted professors (very or extremely), and 54% trusted other cattle producers. In regards to where cattlemen acquired ranching information 94% utilized trade publications or magazines, 90% utilized university or extension, 70% utilized state or national cattlemen’s meetings, and 52% utilized social media. The top three reasons why survey participants would choose to adopt a new ranching practice included increases profitability 79%, improves animal health 78%, and expected benefits greatly outright the cost or effort to implement 51%. Meanwhile, only 18% of ranchers selected improving environmental health as one of their top 3 reasons for adopting a new ranching practice. In terms of best management practices, 77% of producers stated they had a grazing management practice, however only 29% had their plane written down. Finally, the survey indicated that ranchers who were male, had been through the Beef Quality Assurance training, and were enrolled in a land assistance program were more likely to state that joining a sustainability program would be beneficial to their operation (P < 0.05). Overall, this survey provides the necessary insight into why and how ranchers learn about new ranching practices and provides a possible framework for how to develop successful ranching educational and sustainability programs in the future.

Urbanisation threats to dairy cattle health: Insights from Greater Bengaluru, India

Complex urbanisation dynamics, on the one hand, create a high demand for animal products, and on the other hand put enormous pressure on arable land with negative consequences for animal feed production. To explore the impact of accelerated urbanisation on dairy cattle health in urban farming systems, 151 farmers from different parts of the Greater Bengaluru metropolitan area in India were individually interviewed on aspects addressing cattle management and cattle health. In addition, 97 samples of forages from the shores of 10 different lakes, and vegetable leftovers used in cattle feeding were collected for nutritional analysis. Along with the use of cultivated forages, crop residues, and concentrate feed, 47% and 77% of the farmers occasionally or frequently used lake fodder and food leftovers, respectively. Nutritionally, lake fodder corresponded to high-quality pasture vegetation, but 43% of the samples contained toxic heavy metals such as arsenic, cadmium, chromium, and lead above official critical threshold levels. Therefore, lake fodder may affect cows’ health if consumed regularly; however, heavy metal concentrations varied between lakes (P < 0.05), but not between fodder types (P > 0.05). Although 60% of the interviewed farmers believed that their cows were in good health, logit model applications revealed that insufficient drinking water supply and the use of lake fodder negatively impacted cattle health (P < 0.05). While it remains unknown if regular feeding of lake fodder results in heavy metal accumulation in animal products, farmers and farm advisors must address this and other urbanization-related challenges to protect cattle health.Graphical abstract

Farm advisors play a key role in integrating crop-livestock at the farm level: perceptions and experiences in Brazil and France

ABSTRACT Purpose Integrated crop-livestock systems (ICLS) can foster agroecological transitions. However, knowledge on how extension services influence such systems is still lacking. The manuscript analyzes ICLS advisors’ perceptions of the conditions toward recoupling crops and livestock at the farm level. Methodology/Approach We conducted and analyzed 20 semi-structured interviews with advisors and project managers currently working with ICLS in Brazil and France. Findings The results revealed the following advisors’ activities undertaken to support recoupling crop and livestock systems: i) gathering ICLS knowledge by building a network as a knowledge source, along with mobilizing and combining tools and skills, ii) communicating and facilitating arrangements between farmers and farmers´ groups, iii) supporting ICLS co-design by assisting farmers in setting goals and plans, and iv) assisting on-farm transitions by supporting implementation and monitoring. Practical implications This research highlights the key role of advisors in the transition toward the recoupling of crops and livestock at the farm level. ICLS advising could be improved and simplified with better-adapted tools, training to acquire knowledge, and skills specific to the ICLS context. Theoretical implications Systemic thinking, facilitation, communication, and mobilizing a broad network to exchange knowledge are key requirements for advising complex systems such as ICLS. This is a typical case of a ‘knowledge brokering’ approach in which advisors engage in systemic facilitation to encourage innovation adoption. Originality Our analysis provides promising insights into the specific advisor experiences in the transition towards adopting agroecological approaches, such as ICLS. This research opens avenues for future research to encourage ICLS adoption.
