Post-harvest losses refer to food losses that occur between harvest and consumption, i.e. before the product reaches consumers. The objective of this study was to establish a diagnostic and evaluative situation of the three sectors tomato, potato and cabbage, in terms of post-harvest losses (PHL) at the various levels of the value chain in high production areas in Niger. On one hand, 12 groups of around 60 members each were interviewed in focus groups separately, and 120 producers (10 producers per group and by product) were investigated on the other hand. The study identified the different types of PHL, the extent of these losses, the main factors behind these losses, their impact on the producer’s income and their consequences on the food and nutritional security of households. It also made it possible to identify the strategies adopted by producers to cope with these significant losses. The results of this study showed that most of the PHL are caused by physical, microbiological and physiological factors, except for potatoes where the bad faith of wholesalers devaluating an important quantity of the product, remains the main constraint causing enormous qualitative losses to producers (about 35 %). The study filled a gap in the field of post-harvest food losses, particularly in the case of market gardening. The professionalization of actors in pre-harvest techniques and their support with small processing and/or preservation equipment’s remain an alternative.

Abstract: (french)
Les pertes-post récoltes désignent les pertes alimentaires qui sont enregistrées entre la récolte et la consommation, c’est-à-dire avant que le produit ne parvienne aux consommateurs. L’objectif de cette étude était d’établir une situation diagnostique et évaluative des trois filières tomate, pomme de terre et chou, en termes de pertes post-récolte (PPR) au niveau de différents maillons de la chaîne de valeur dans les zones de grandes productions au Niger. D’une part, 12 groupements d’une soixantaine de membres chacun ont été entretenus en «focus group» séparément et, 120 producteurs (10 producteurs par groupement et par spéculation) ont été enquêtés individuellement, d’autre part. L’étude a permis d’identifier les différents types de PPR, l’ampleur de ces pertes et les principaux facteurs à l’origine de ces pertes. Les résultats de cette étude ont montré que l’essentiel des PPR est causé par les facteurs physiques, les paramètres microbiologiques et physiologiques, sauf pour la pomme de terre où la mauvaise foi des grossistes dévaluant une quantité importante de produit, demeure la principale contrainte causant des pertes qualitatives énormes aux producteurs (environ 35%). L’étude a comblé un vide dans le domaine des pertes alimentaires post-récolte, particulièrement dans les cas des spéculations maraîchères. La professionnalisation des acteurs en techniques pré-récoltes et leur accompagnement avec des petits équipements de transformations et/ou conservation restent une alternative.
