Food diversity is a challenging issue for sustainable agrifood systems. Diets are increasingly dependent on branded packaged foods. Therefore, the crop diversity offered in the food market through these products is of particular importance. We scrutinize this diversity for some crops under great societal challenge: pulses. Based on the product laun...
This research explores how Brazilian activist groups participate in Facebook to coordinate their social struggles, based on a lexical analysis of publications on 529 pages, published between 2013 and 2017. These groups set up two main repertoires of action by mobilizing Facebook as an arena for challenging political action and a tool for coordinati...
Food biodiversity is a challenging issue for sustainable agri-food systems, particularly in the European one-health context. Most often studied at the levels of agricultural systems and food diets, few works examined plant species diversity used in food products. As the market is a main driver for farmers’ crop choices, analyzing how crop biodivers...
This article explores the results of a study on media participation on Twitter in 2018/2019 perceived as contributing to far right and Islamist radical ideologies, in 7 European countries. By combining online ethnography and big data approaches, we see that online far right extremism in Europe is active and ranks are growing, while Islamist extremi...
Increasing legume diversity in food will significantly contribute to sustainable and healthy agrifood systems. But this seems difficult to achieve due to strong path-dependency in the agrifood sector and needs to be better assessed to define sound sustainability transition policies. We analysed 100,000 food product innovations with legume ingredien...
La nécropolitique bolsonarienne et les assauts renouvelés à l'environnement viennent réaffirmer l'emprise de l'agrocapitalisme au Brésil. Le néolibéralisme autoritaire assuré par Jair Bolsonaro s'inscrit dans la lignée d'une histoire de masculinité coloniale et de processus assurés depuis le golpe : démantèlement des protections environnementales,...
There is a lack of methods and tools to reveal robust information on the ingredients used in packaged foods. To tackle this challenge, we developed an original method to parse ingredient lists of packaged foods. We built a dataset of food product innovations with their parsed ingredient lists. We explain the parser algorithm used to provide this da...

This article analyzes the spread of unreliable information on Twitter during the 2017 French presidential campaign, focusing on the use of mobile phones with regard to information-sharing behavior. The corpus is composed of 38,346,765 tweets, posted by 2,163,812 supporters of the five main French political parties, from November 25, 2016 to May 12,...
This paper discusses the forms of collective action (i.e. “repertoire of action”, Tilly 2013) employed by activists to better identify the digital forms of collective action (“digital repertoires of social networks” Chadwick, 2007). By means of a longitudinal approach of the lexical material extracted from Facebook posts and conversations, it demon...
Si l'élection de Jair Bolsonaro a révélé, en 2018, la vivacité des mouvements libéraux et d'extrême droite dans le champ politique brésilien, elle ne doit pas occulter la lente structuration d'une gauche, militante et extra-institutionnelle, en amont et en aval des grandes journées de manifestations de juin 2013. Cet article rend compte de cette st...
Cette recherche analyse les modes de propagation des sources d’information peu fiables au sein de Twitter lors de l’élection présidentielle française de 2017 en évaluant plus précisément le rôle des téléphones mobiles dans les échanges d’idées et de contenus. Elle montre que l’usage de l’application mobile de Twitter défavorise le partage d’article...

Ou...
Cette recherche montre plus précisément que les contenus artistiques et l’agenda des événements culturels ont occupé une place centrale dans ces répertoires d’action en ligne. Ils ponctuent l’ordinaire des échanges d’informations entre les militant·es, notamment en dehors des périodes et des événements de cristallisation des luttes. Ils ont favoris...
L’article présente une analyse des réseaux d’échanges d’informations mis en place au sein de Facebook par les principales communautés politiques françaises lors de la campagne présidentielle de 2017. Il montre que ces communautés développent des logiques de partage d’information profondément homophiles, sur un plan idéologique, dans la mesure où el...
Grain-legume crops are important for ensuring the sustainability of agrofood systems. Among them, pulse production is subject to strong lock-in compared to soya, the leading worldwide crop. To unlock the situation and foster more grain-legume crop diversity, scientific research is essential for providing new knowledge that may lead to new developme...
Spatial and temporal diversification of cropping systems (CS) is recognized as a relevant alternative to move towards sustainable agriculture. It could be achieved by several agronomic levers, and more particularly by lengthening and diversifying crop rotations notably by the introduction of legumes, crop mixtures and multi-services cover crops (CC...

Ces expériences diverses, selon le genre et la place sociale notamment, s...
