Cette recherche sur la banlieue de Bologne pendant les XVIIe, XVIIIe et XIXe siècles montre que si la mortalité infantile a connu une baisse, elle reste toutefois à un niveau élevé à la fin du XIXe siècle : il s'agit-là d'un des traits majeurs de l'ensemble de la mortalité dans la Péninsule. On peut expliquer ce taux élevé par la permanence de certaines maladies infectieuses ou parasitaires, dont l'étude graphique révèle à la fois le caractère saisonnier et l'effet différentiel, à savoir qu'elles ont surtout frappé les enfants les plus jeunes.

AbstractPalm oil is the world most used vegetable oil and its use as food ingredient is criticized for creating environmental, socio‐economic, and health sustainability challenges. In Europe, the debate on palm oil sustainability has strongly intensified in the latest years involving several agri‐food chain actors and stakeholders. The research explores Twitter content of key palm oil agri‐food chain actors on palm oil multiple sustainability dimensions, focusing on the European context. First, the study applied a qualitative deductive approach to categorize palm oil sustainability dimensions. Second, among the 463 palm oil agri‐food chain companies identified, 198 have an active Twitter account, including world palm oil producers, European bakery and chocolate manufacturers, and European food retailers. One hundred seven accounts tweet on palm oil. Third, a term frequency analysis and an in‐depth textual analysis of tweets on palm oil sustainability issues were carried out. Results confirms that all agri‐food chain actors communicate about palm oil sustainability, adopting a multi‐dimension outlook. Palm oil producers actively use Twitter to promote palm oil sustainability, whereas European manufacturers and retailers limit their activity to react to consumers' questioning. Whereas palm oil producers tend to shape consumers' opinion over the benefits and the opportunities of palm oil use, food manufacturers and retailers adopt a purely informative approach on sustainability certification, avoiding the engagement over sensitive issues. Health is the most mentioned sustainability dimension. The study also confirms differences between agri‐food chain actors' marketing communication. Finally, the study confirms that, in the case of sensitive issues, as for palm oil sustainability, Twitter is as able to drive companies' communication.

This study evaluated productivity dynamics and identified sources of productivity growth in Italian tomato production and processing. We used a stochastic frontier input distance function with four error components—heterogeneity, statistical noise, persistent and transient inefficiency—and a four-step estimation procedure with a system generalized method of moments (GMM) estimator in the first step to address the endogeneity problem. The results reveal significant differences in the productivity and efficiency of tomato production and processing. Moreover, there are considerable differences among the different sizes of tomato producers, with the main variations observed for scale efficiency. While tomato processors operate at an optimal production size, tomato producers are characterized by considerable economies of scale, especially small producers. These results thus suggest that there is significant opportunity for technical efficiency improvements at both stages of the value chain. Finally, due to improvements made to scale efficiency, extensive productivity growth was observed for the group of small tomato producers.

"Putting Solutions on the Table" was the title of a webinar on successful approaches and interventions to support more sustainable food consumption behaviours in the EU. The webinar was organised by the H2020 project VALUMICS and held in July 2021. The purpose of the webinar was to share and discuss insights from existing evidence from hands-on, behaviourally-informed pilot interventions and strategies suitable for the food industry and policy makers in order to drive more sustainable food consumption practices. 170 persons registered for the event and more than 90 joined live to hear and interact on several key questions, notably: • How can we move towards a healthier and more sustainable food consumption, in view of the EU food consumption policy landscape, particularly the Farm to Fork Strategy? • Which sustainable food consumption targets lie ahead of us? • How can food consumption behaviours and solution-oriented interventions trigger and shift towards a more sustainable future? • How are these behavioural interventions applied in real life contexts and what might we learn from them?

Publisher's version (útgefin grein) ; Transitioning agri-food systems towards increased sustainability and resilience requires that attention be paid to sustainable food consumption policies. Policy-making processes often require the engagement and acceptance of key stakeholders. This study analyses stakeholders' solutions for creating sustainable agri-food systems, through interviews with a broad range of stakeholders including food value chain actors, non-governmental organizations, governmental institutions, research institutions and academic experts. The study draws on 38 in-depth, semi-structured interviews conducted in four European countries: France, Iceland, Italy and the UK, as well as three interviews with high-level EU experts. The interviewees' solutions were analysed according to a five-category typology of policy tools, encompassing direct activity regulations, and market-based, knowledge-based, governance and strategic policy tools. Most of the identified solutions were located in the strategic tools category, reflecting shared recognition of the need to integrate food policy to achieve long-term goals. Emerging solutions-those which were most commonly identified among the different national contexts-were then used to derive empirically-grounded and more universally applicable recommendations for the advancement of sustainable food consumption policies. ; The VALUMICS project "Understanding Food Value Chain and Network Dynamics" received funding from the European Union's Horizon 2020 research and innovation programme, under grant agreement No. 727243. https://valumics.eu/. The authors would like to thank the interviewees for their participation in this study, and the two anonymous reviewers for providing useful comments. ; Peer Reviewed

System dynamics and agent-based simulation modelling approaches have a potential as tools to evaluate the impact of policy related decision making in food value chains. The context is that a food value chain involves flows of multiple products, financial flows and decision making among the food value chain players. Each decision may be viewed from the level of independent actors, each with their own motivations and agenda, but responding to externalities and to the behaviours of other actors. The focus is to show how simulation modelling can be applied to problems such as fairness and power asymmetries in European food value chains by evaluating the outcome of interventions in terms of relevant operational indicators of interorganisational fairness (e.g., profit distribution, market power, bargaining power). The main concepts of system dynamics and agent-based modelling are introduced and the applicability of a hybrid of these methods to food value chains is justified. This approach is outlined as a research agenda, and it is demonstrated how cognitive maps can help in the initial conceptual model building when implemented for specific food value chains studied in the EU Horizon 2020 VALUMICS project. The French wheat to bread chain has many characteristics of food value chains in general and is applied as an example to formulate a model that can be extended to capture the functioning of European FVCs. This work is to be further progressed in a subsequent stream of research for the other food value chain case studies with different governance modes and market organisation, in particular, farmed salmon to fillet, dairy cows to milk and raw tomato to processed tomato. ; Peer Reviewed

Why do European consumers buy food the way they do? Which key factors drive Europeans' food consumption patterns and how could they be used to create pathways toward sustainability? The VALUMICS project's evidence-based report provides insights to what influences consumers the most in their food choices. The report 'Food consumption behaviours in Europe' brings together data across various countries, such as the United Kingdom, Germany, France and Italy. Through in-depth literature research, focus groups and expert consultations, the report provides a better understanding of the status quo, trends, motivations as well as barriers and opportunities towards more sustainable food consumption behaviours in general. The focus is on five product categories: Beef, dairy, salmon, tomatoes and bread. Findings indicate that food consumption behaviours can be largely attributed to price considerations, family eating habits, health concerns or social contexts of consumers. The report highlights that environmental awareness and values play little to no role in the consumption patterns. "Certain changes can only be made by politics, or the EU in this case, which should impose high sustainability limits and standards: for example, banning disposable plastics is a good start. Until certain management practices are allowed, it is difficult to behave more sustainably because everyone else can be more economically competitive" noted one of the experts interviewed for the report. Other actions suggested in the report include fostering stronger communication channels between producers and consumers, with the potential for increasing the resilience of food value chains as well as using behavioural insights to inform strategies and action plans for more sustainable food consumption. The report 'Food consumption behaviours in Europe' is the first in a series of VALUMICS publications focusing on analysing food consumption. The upcoming reports look into successful interventions for sustainable food behaviour, multi-stakeholder ...

The functioning of food value chains entails a complex organisation from farm to fork which is characterised by various governance forms and externalities which have shaped the overall food system. VALUMICS food value chain case studies: wheat to bread, dairy cows to milk, beef cattle to steak, farmed salmon to fillets and tomato to processed tomato were selected to enable explorative and empirical analysis to better understand the functioning of the food system and, to identify the main challenges that need to be addressed to improve sustainability, integrity, resilience, and fairness of European food chains. The VALUMICS system analysis was executed through four operational phases starting with Groundwork & analysis including mapping specific attributes and impacts of food value chains and their externalities. This was followed by Case study baseline analysis, which provided input to the third phase on Modelling and exploration of future scenarios and finally Policy and synthesis of the overall work. This report is an overall synthesis of the VALUMICS results as follows: • Key findings from the VALUMICS project on the functioning of European food value chains and their impacts on more sustainable, resilient, fairer, and transparent food system are summarised through a compilation of 25 Research Findings and Policy Briefs. • By highlighting the major contributions from the research activities throughout the four phases of the VALUMICS project, this report delivers an assessment of various factors influencing sustainability, resilience, efficiency and fairness and effective chain relationships of different food value chains, and their determinants. • The synthesis of the outcome allows the identification of opportunities and challenges characterising the functioning of food supply chains, and thus, the prospects and potentials for strengthening the EU food sector. ; Citation: Olafsdottir, G., Bogason, S., Aubert, P.M., Barling, D., Thakur, M., Duric, I., Nicolau, M., McGarraghy, S., Sigurdardottir; H., ...
