    Apis mellifera - COLOSS - coronavirus - COVID-19 - extension - honey bee - pandemic - research

    The socio-economic impacts of COVID-19 on society have yet to be truly revealed; there is no doubt that the pandemic has severely affected the daily lives of most of humanity. It is to be expected that the research activities of scientists could be impacted to varying degrees, but no data exist on how COVID-19 has affected research specifically. Here, we show that the still ongoing COVID-19 pandemic has already diversely and negatively affected bee research at a global level. An online survey disseminated through the global COLOSS honey bee research association showed that every participant (n = 230 from 56 countries) reported an impact on one or more of their activities. Activities that require travelling or the physical presence of people (meetings and conferences, teaching and extension) were affected the most, but also laboratory and field activities, daily operations, supervision and other activities were affected to varying degrees. Since the basic activities are very similar for many research fields, it appears as if our findings for bee research can be extrapolated to other fields. In the light of our data, we recommend that stakeholders such as governments and funding bodies who support research should facilitate the wide implementation of web-based information technology required for efficient online communication for research and education, as well as adequately loosened restriction measures with respect to field and laboratory work. Finally, increased flexibility in administration and extension of research grants and fellowships seem to be needed. It is apparent that adequate responses by all stakeholders are required to limit the impact of COVID-19 and future pandemics on bee science and other research fields.

    Advisory services - AKIS - extension - farming styles - Norway - transformation
    Purpose: In light of the discussion on ‘best-fit’ in pluralistic advisory systems, this article aims to present and discuss challenges for advisory services in serving various types of farmers when they seek and acquire farm business advice. Design/methodology/approach: The empirical basis is data derived from four workshops, five interviews with staff from advisory organizations, and interviews with 11 farmers. Findings: Emerging configurations serve different types of farmers, that is, private advisors serve different clients in different ways; these could be considered subsystems within the overall advisory system. Practical implications: Best-fit configurations of advisory services exist within a country setting in response to farmers’ information demands and how they seek information, as well as public goals of the advisory system, and lead to advisory subsystems. Policy-makers should monitor the emergence of these subsystems and become active participants in some of them, in line with the concept of the public sector as regulator of private and commercial advisory systems. Theoretical implications: Best-fit has been mainly explored at country level, but this study shows that, within countries, different advisory service configurations are formed. So, best-fit should not be considered at national level only, in view of subsystems which can have wider or narrower boundaries. More broadly, the concept of Agricultural Knowledge and Innovation Systems (AKIS) should not be confined to the national level, for example, in view of farmer specializations within countries and the international dimensions of advisory systems. Originality/value: The originality lies in the further unraveling of heterogeneity within AKIS and what this implies for advisory service delivery configurations.

    SAGCOT, the ‘Southern Agricultural Growth Corridor of Tanzania’, is a coordinated initiative to boost agricultural output in southern Tanzania through public and private investment, to improve food security, reduce rural poverty and sustain the environment. The ‘Sustainability and Inclusion Strategy for Growth Corridors in Africa’ (SUSTAIN-Africa) programme by the International Union for Conservation of Nature (IUCN) develops and demonstrates climate resilient solutions for water security and inclusive land resource and agricultural development in growth corridors and areas of intensive economic development in Africa. To develop an efficient, competitive and sustainable agricultural sector in SAGCOT, possible adverse effects of pesticide use need to be addressed and minimized. For this purpose a scoping study was conducted, consisting of a literature survey, a scoping mission and a stakeholder workshop. The study revealed that there are many issues related to pesticide management and pesticide risks that need attention when the SAGCOT is further developed and pesticide use increases. The most important recommendations of the study are (1) better implementation and enforcement of current rules and regulations for pesticides, (2) training and awareness creation for pesticide users, (3) creation of a multi-stakeholder platform for exchange on best pest and pesticide management practices in the SAGCOT, (4) a regulatory body at the local government authority level to enforce/monitor pesticide management and life cycle, and (5) development of a monitoring and evaluation framework on pesticides for the SAGCOT.

    Bos en bosbeheer veranderen continu. Met de ontwikkeling van de productiegerichte bosbouw van vijftig jaar geleden naar een bosbeheer gericht op meervoudige functievervulling in een dichtbevolkte samenleving veranderde ook de rol van de beheerder. Dit vraagt om andere kennis en vaardigheden van de beroepsgroep en andere organisatievormen van onderwijs en onderzoek. De Koninklijke Nederlandse Bosbouw Vereniging (KNBV) fungeert sinds de oprichting in 1910 als vakvereniging door en voor mensen uit de sector, volledig draaiend op vrijwilligers. De veranderingen in de sector en het werkveld vragen ook om een andere rol van de beroepsvereniging.
    Understanding healthful eating from a salutogenic perspective

    The biomedical model of health orients towards pathogenesis, the study of disease origins and causes. The starting point is to understand determinants of ill-health, and health is defined in this model as the absence of disease. When applied to nutrition research, the underlying assumption is that eating is a physiological act, and that eating supports physical health. This risk-oriented, pathogenic view also underlies the search for determinants of unhealthful eating. However, there is such an emphasis on finding risk factors, that the biomedical model overlooks the fact that individuals also possess, or have access to, factors that support healthful eating. As a result, very little is known on factors that enable healthful eating and how these factors can be used to complement current health promotion strategies. The overall aim of this research was to contribute to a better understanding of healthful eating in the context of everyday life. We applied a complementary research framework, the salutogenic model of health, to 1) map factors underlying the development of sense of coherence (SOC); 2) study which of these factors are predictors for healthy eating; 3) unravel how people develop healthful eating practices in everyday life; and 4) integrate this understanding and provide building blocks for nutrition promotion. This research employed a mixed research design, using cross-sectional survey research and in-depth interviews.

    Chapter 2 explored the possibilities of applying the salutogenic framework as a complementary approach to biomedical-oriented nutrition research and practice. Nutrition research takes a mostly biomedical-oriented approach to better understand risk factors that determine unhealthful eating. Though relevant for curative medicine, such an approach limits the evidence base for health promotion, which is guided by the principles that personal and social resources are preconditions for health and well-being. Moreover, biomedical-oriented nutrition promotion takes a reductionist approach and studies and enacts upon individual or the external environment separately. Disjointedly studying and enacting upon people and context may be easier, yet it does not do justice to reality and limits the relevance and applicability in everyday eating situations. The salutogenic model of health can provide complementary knowledge on what is already known through biomedical approaches. It guides the study of the dynamics between people and their environment and how health develops from this interaction. Since salutogenesis guides the study of health as an interplay between physical, mental, and social factors, it is more in line with how people experience eating in their everyday lives. In the study described in chapter 3, we examined individual, social, and physical-environmental factors that underlie SOC. Dutch adults (n=781) participated in a cross-sectional study examining the relationship between SOC and a set of individual, social- and physical-environmental factors. The main findings indicate that high SOC was significantly (p<.05) associated with a diverse set of factors including lower doctor oriented multidimensional health locus of control (MHLC); higher satisfaction with weight; higher situational self-efficacy for healthy eating; lower perceived social discouragement for healthy eating; higher perceived levels of neighborhood collective efficacy; and higher perceived neighborhood affordability, accessibility and availability of healthy foods. Non-significant factors (p≥.05) included gender; employment status; education level; cohabitation; BMI; nutrition knowledge; internally oriented MHLC; chance oriented MHLC; and perceived social support for healthy eating. These findings are relevant since they can inform the design of nutrition interventions that target factors that strengthen SOC and provide building blocks for a healthier life orientation. Next, the study in chapter 4 aimed to determine a set of individual, social and physical-environmental factors that predict healthy eating practices in a cross-sectional study of Dutch adults. Data were analyzed from participants (n=703) that completed the study’s survey and logistic regression analysis was performed to test the association of survey factors on the outcome variable high dietary score. In the multivariate logistic regression model, five factors contributed significantly (p<.05) to the predictive ability of the overall model: being female; cohabitation; a strong sense of coherence; flexible restraint of eating; and self-efficacy for healthy eating. Non-significant factors (p≥.05) in the multivariate logistic regression model included age; employment status; net monthly household income; education level; nutrition knowledge; internally oriented MHLC; perceived social support and discouragement for healthy eating; perceived neighborhood collective efficacy and perceived neighborhood affordability, availability and accessibility of healthy foods. Findings complement what is already known of the factors that relate to poor eating practices. This can provide nutrition promotion with a more comprehensive understanding of the factors that both support and hinder healthy eating practices.

    Lastly, the qualitative study described in chapter 5 examined a group of healthy eaters and explored life experiences and coping strategies that foster healthful eating through narrative inquiry. The study was undertaken with seventeen Dutch women (aged 36- 54 years) in the highest quartile of dietary quality index scores. The main findings showed that life experiences gave rise to coping strategies that enabled healthful eating. Childhood experiences included: accustomed to non-processed foods and positive child-parent interactions. Adulthood experiences included: regained stability and structure in stressful life events and forged positive experiences with food. Coping strategies included: organizing eating in an uncomplicated manner; creativity in the kitchen; valuing good food with good company; approaching eating with critical self-awareness; and applying craftiness and fortitude during difficult moments. The findings suggest that there is an interplay between life experiences and coping strategies, and this mechanism underpins healthful eating. Findings offer potential entry points for nutrition promotion to foster healthful eating.

    When integrating the research findings in chapter 6, we found that healthful eating results from three composite factors: balance and stability, sense of agency, and sensitivity to the dynamics of everyday life. Firstly, healthful eating results from balance and stability in life, represented by a strong SOC, which characterizes a balanced mixture of giving meaning to eating as an integral part of life, comprehending its importance to oneself, and having competencies to manage its organization in the everyday social context. In the life course, healthful eating also results from the ability to regain stability and structure in stressful life events and craftiness and fortitude during difficult moments. Healthful eating is also rooted in a sense of agency (the feeling of being in control of one’s own actions), with regards to the ability to take action related to eating and life in general. This sense of agency is enabled through flexibility, lower doctor oriented MHLC, applying creativity in the kitchen, and approaching eating with critical self-awareness. Thirdly, healthful eating results from a sensitivity to the dynamics of everyday life, with regards to the how people deal with and navigate through everyday challenging situations by applying individual- and context-bound factors including situational self-efficacy, organizing eating in an uncomplicated manner, valuing good food with good company, and perceiving less social discouragement for healthy eating from family and friends.

    Few of the factors associated with SOC and healthful eating converged with risk factors for unhealthful eating found in previous studies, including coping, self-efficacy, restraint of eating, and living situation. Our findings show that the set of factors related to the origins of health substantially diverged from the set of factors related to the origins of disease. From this, we conclude that the “origins of health” differ from the “origins of disease”. Hence, factors that foster and support healthful eating are not simply the reversed version of the factors known to increase the risk of unhealthful food choices. This implies that a different set of factors should inform health promoting strategies, in addition to the factors informing strategies targeting the prevention of diet-related illnesses.

    The new insights brought forth in this research provide building blocks for salutogenic-oriented nutrition promotion. 1) Strategies should take a more holistic orientation to food and eating, emphasizing a balance between physical, social, and mental health. Similarly, dietary guidelines should emphasis more than what and how much to eat for physical health and also consider the social and mental dimensions.

    2) Nutrition promotion should develop strategies to support a healthful orientation to life. Through strengthening SOC, people can become more capable of coping with any situation or challenge, independent of whatever is happening in life. Nutrition promotion should also strengthen more general health promotion factors including mindfulness, critical thinking, and stress management because these skills support adaptive behavior when life circumstances change. 3) Strategies should facilitate health-directed learning processes through positive interactions and experiences with food. For instance, strategies that support health-directed learning processes should improve food-related procedural knowledge such as food literacy and cooking skills. They should also include socially-embedded learning experiences involving the selection, purchase, and preparation of healthful food; encourage positive parent-child interactions at the dinner table; and recommend that people cook regularly with partners, family or friends.

    This baseline report of the Dairy Business Information Service and Support (DairyBISS) project presents the findings of a baseline survey among 103 commercial farms and 31 firms and advisors working in the dairy value chain. Additional results from the survey among commercial dairy farms are described in an additional report. The findings validate the main strategies of the project. Farms and firms are interested in joining a dairy business platform that includes members from the entire value chain. While currently there is gap between the demand and supply of good quality business information and advisory services, there is a willingness to pay for advisory services. Among advisors there is a need for training on technical topics along the dairy value chain and there is an interest in forming an advisor network to share experiences.

    Dietary restriction (DR), defined as a moderate reduction in food intake short of malnutrition, has been shown to extend healthy lifespan in a diverse range of organisms, from yeast to primates. Reduced signalling through the insulin/IGF-like (IIS) and Target of Rapamycin (TOR) signalling pathways also extend lifespan. In Drosophila melanogaster the lifespan benefits of DR can be reproduced by modulating only the essential amino acids in yeast based food. Here, we show that pharmacological downregulation of TOR signalling, but not reduced IIS, modulates the lifespan response to DR by amino acid alteration. Of the physiological responses flies exhibit upon DR, only increased body fat and decreased heat stress resistance phenotypes correlated with longevity via reduced TOR signalling. These data indicate that lowered dietary amino acids promote longevity via TOR, not by enhanced resistance to molecular damage, but through modified physiological conditions that favour fat accumulation.
    Yummy” versus “Yucky”! Explicit and implicit approach-avoidance motivations toward appealing and disgusting foods

    Wanting and rejecting food are natural reactions that we humans all experience, often unconsciously, on a daily basis. However, in the food domain, the focus to date has primarily been on the approach tendency, and researchers have tended not to study the two opposing tendencies in a balanced manner. Here, we develop a methodology with which to understand people's implicit and explicit reactions to both positive (appealing) and negative (disgusting) foods. It consists of a combination of direct and indirect computer-based tasks, as well as a validated food image stimulus set, specifically designed to investigate motivational approach and avoidance responses towards foods. Fifty non-dieting participants varying in terms of their hunger state (hungry vs. not hungry) reported their explicit evaluations of pleasantness, wanting, and disgust towards the idea of tasting each of the food images that were shown. Their motivational tendencies towards those food items were assessed indirectly using a joystick-based approach-avoidance procedure. For each of the food images that were presented, the participants had to move the joystick either towards or away from themselves (approach and avoidance movements, respectively) according to some unrelated instructions, while their reaction times were recorded. Our findings demonstrated the hypothesised approach–avoidance compatibility effect: a significant interaction of food valence and direction of movement. Furthermore, differences between the experimental groups were observed. The participants in the no-hunger group performed avoidance (vs. approach) movements significantly faster; and their approach movements towards positive (vs. negative) foods were significantly faster. As expected, the self-report measures revealed a strong effect of the food category on the three dependent variables and a strong main effect of the hunger state on wanting and to a lesser extent on pleasantness.

    This article takes an innovation intermediary perspective to examine farmer cooperative’s (FC) roles in facilitating agricultural innovation and its positioning in the agricultural innovation system (AIS). The article draws experiences from the rapidly emerging FC field in China. Three cases are selected to cross check findings from them and innovation journey analysis is used within each case to understand FCs’ engagement in innovation processes. The findings show that FCs cover a wide range of knowledge intermediation and innovation intermediation functions identified by the literature. FCs recognize the importance to connect technical, social and economic dimensions of farming practice and provide corresponding services to link farmers to relevant actors, like extension agencies, research institutes and supermarkets. Though they mainly work through bilateral relationships as opposed to acting as a systemic intermediary, they could take the role of coordinator in the service system and bridge the gap between the research and policy system and everyday farming practice, especially in the absence of a systemic coordinator. However, their legitimacy as intermediary might be challenged due to the potential conflicts with governments, market actors or their members, and their local position may provide insufficient clout for developing durable relationships with relevant actors.

    Innovation is receiving increased attention among policymakers as a means of addressing sustainable economic development challenges. However, a range of factors such as inappropriate physical and knowledge infrastructures, incoherence of institutional frameworks, or lack of specific capabilities may have a negative impact on the functioning of the agricultural innovation system. The purpose of this paper is to apply a comprehensive innovation systems analytical framework, reconciling analyses of systemic structures, functions, failures and merits of innovation systems to assess and compare the performance of the agricultural innovation systems of Scotland and the Netherlands. To achieve this an analytical framework was drawn up based on the available literature, and through a process that included document analysis and a series of semi-structured interviews and workshops with experts in the two countries the agrifood sectors were empirically assessed. In both countries, systemic failures in terms of actors’ interactions and competencies as well as market and incentive structures were revealed. However, differences emerge between the two countries that appear to relate more to social and cultural (soft institutions) differences rather than the formal legal and regulatory frameworks (hard institutions)

    Internationally, extension has been a support instrument used by governments and commercial interests for improving agricultural production for hundreds, if not thousands of years. The application of extension theory and practice for natural resource management (NRM) is a more recent undertaking. However, over the last 20+ years, agencies sponsoring extension services appear to have lost confidence in extension’s ability to achieve desired outcomes. In Australia, Greg Leach’s PhD research has sought to understand the barriers and bottlenecks which have prevented the implementation of extension policy by the Queensland State Government. His research enquired into the institutionalisation of extension in Queensland, as well as approaches and mechanisms for negotiating extension policy at the national scale from 2000 to 2010. Learnings from the author’s involvement in operationalising a network of extension leaders from across Australia, underpin broader recommendations on institutionalising extension policy, and advice for extension policy to aid achievement of NRM outcomes.

    multivariate probit model - rural-development - extension
    The aim of this paper is to identify and assess the role played by innovative extension services in affecting farmers’ strategy. More specifically we implement a multivariate probit model to evaluate the effects of different types of extension services introduced by a reform in the domain of Agricultural Knowledge and Innovation System (AKIS) in Italy. The results show that both generalist and specialized services could play a major role in farmers’ value creation strategies. They also confirm that different strategies for creating value are jointly implemented. Finally, they show that a further improvement in the quality of public provision of extension services within regional AKIS and a greater (systemic) interaction between farmers, rural actors and local networks should be supported

    This paper develops an interdisciplinary conceptual framework demonstrating the role of marketing in managing investor relationships. The framework illustrates how companies can turn investor relationships into market-based assets by analyzing and managing them from a relationship marketing and stakeholder perspective. Marketing can contribute to investor relationship management and increase shareholder value by lowering the cost of equity capital, increasing analyst coverage and stock liquidity, and reducing shareholder activism. An investigation among investor relations professionals working at publicly traded companies in the Euronext 100 stock index demonstrates the framework's empirical validity and provides managerial implications.

    Voedsel leeft en staat volop in de belangstelling. Op veel plaatsen in Nederland zijn er voedselinitiatieven. Streekmarkten worden georganiseerd, school- en moestuinen worden opgezet, de jeugd krijgt smaaklessen en gaat op boerderijbezoek. Voedsel bindt mensen en brengt mensen samen. Verandering van de huidige voedselconsumptie en productie is hard nodig, ondermeer omdat wereldwijd de bevolking toeneemt, voorraden van een aantal cruciale grondstoffen eindig zijn en voedselzekerheid lang niet voor iedereen een gegeven is. Aan de hand van 24 acties van A tot Z laten we zien wat gemeenten (kunnen) doen om de ambities uit de Nota Duurzaam Voedsel te realiseren
