Value-Chain Wide Food Waste Management: A Systematic Literature Review

© 2019, Springer Nature Switzerland AG. The agriculture value chain, from farm to fork, has received enormous attention because of its key role in achieving United Nations Global Challenges Goals. Food waste occurs in many different forms and at all stages of the food value chain, it has become a worldwide issue that requires urgent actions. However, the management of food waste has been traditionally segmented and in an isolated manner. This paper reviews existing work that has been done on food waste management in literature by taking a holistic approach, in order to identify the causes of food waste, food waste prevention strategies, and elicit recommendations for future work. A five step systematic literature review has been adopted for a thorough examination of the existing research on the topic and new insights have been obtained. The findings suggest that the main sources of food waste include food overproduction and surplus, food waste caused by processing, logistical inconsistencies, and households. Main food waste prevention strategies have been revealed in this paper include policy solutions, packaging solutions, date-labelling solutions, logistics solutions, changing consumers’ behaviours, and reuse and redistribution solutions. Future research directions such as using value chain models to reduce food waste and forecasting food waste have been identified in this paper. This study makes a contribution to the extant literature in the field of food waste management by discovering main causes of food waste in the value chain and eliciting prevention strategies that can be used to reduce/eliminate relevant food waste

IDEA4 : une méthode de diagnostic pour une évaluation clinique de la durabilité en agriculture

International audienceAgronomists have developed a wide range of methods and diagnostic tools to qualify or evaluate the situations they encounter at different scales and organization levels (parcel, farm, territory) and to meet various objectives (production, quality and health, soil fertility, biodiversity, diffuse pollution, economic performance, landscape, etc...). Over the past twenty years, societal demand has resulted in a need to both consolidate and broaden the fields of observation to reflect the sustainability of agriculture and its activities. The article shows how the IDEA method (Indicateurs de Durabilité des Exploitations Agricoles or Farm Sustainaibility Indicators), developed since the end of the 1990s, has supported this dynamic while renewing itself several times to finally lead to the new IDEA4. Its new theoretical framework based on twelve objectives assigned to sustainable agriculture and five properties of sustainable agricultural systems allows to conduct a diagnosis according to two complementary analytical grids (three dimensions and five properties of sustainability) based on the aggregation of 53 indicators. A farm case study illustrates how the use of IDEA4 questions the farmer about the situation of its farm and opens up possibilities for further progress towards greater sustainability.Les agronomes ont développé de très nombreuses méthodes de diagnostics pour répondre à des objectifs variés et qualifier les situations observées à différentes échelles et niveaux d'organisation (parcelle, exploitation agricole, territoire). La demande sociétale implique d'élargir les champs d'observation pour rendre compte de la durabilité de l'agriculture. La méthode IDEA (Indicateurs de Durabilité des Exploitations Agricoles), développée depuis la fin des années 1990, a accompagné cette dynamique tout en se renouvelant à trois reprises pour donner lieu à la nouvelle version 4. Son nouveau cadre théorique, basé sur 12 objectifs et 5 propriétés d'une agriculture durable, permet de conduire un diagnostic selon deux grilles de lecture complémentaires (3 dimensions de durabilité et 5 propriétés des systèmes agricoles durables) s'appuyant sur l'agrégation de 53 indicateurs. L'étude de cas illustre comment l'usage d'IDEA4 suscite un questionnement de l'agriculteur sur la situation de sa ferme et lui ouvre des pistes pour progresser vers plus de durabilité
