Les profils de pertes post-récolte (profils PHL) quantifient les pertes attendues – en pourcentage – pour chaque étape de la chaîne de valeur post-récolte. Ces données de pertes sont tirées de la littérature scientifique et ventilées par culture, type d'exploitation et type de climat (d'après la classification climatique de Köppen-Geiger). Ces profils fournissent des chiffres de pertes en pourcent pour les différentes cultures au long de la chaîne de valeur dans des conditions variables et sont mis à jour à mesure que de nouvelles recherches sont disponibles.
Nous cherchons toujours à améliorer nos estimations de pertes post-récolte. Si vous connaissez des études intéressantes ou si vous avez des données de terrain que nous pourrions inclure dans notre algorithme, n'hésitez pas à nous envoyer un courriel à info@aphlis.net
