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.
