Abstract

La demande alimentaire mondiale progresse depuis les années 1960, en fonction de la croissance de la population et de la croissance économique. Cette tendance va s'amplifier, avec une population mondiale estimée à 9,2 milliards de personnes en 2050. La production alimentaire vivrière devrait ainsi augmenter de 70% pour répondre à ces besoins (FAO, 2009). La demande en produits carnés devrait progresser de 95% entre 2010 et 2050 (Cepi, 2017), mais également celle pour les produits laitiers et pour les fruits et légumes, le régime alimentaire des populations se diversifiant au fur et à mesure de l'élévation du niveau de vie.
