Ressources en eau
Le monde doit produire environ 60 pour cent de nourriture en plus d'ici 2050 pour assurer la sécurité alimentaire mondiale, et ce, tout en conservant et en améliorant la base des ressources naturelles. L'eau est un intrant majeur dans l'approvisionnement alimentaire– depuis la production sur le terrain jusqu'aux différentes étapes de la chaîne de valeur. L'eau est également nécessaire pour répondre aux besoins personnels et domestiques, pour les productions énergétique et industrielle, et pour maintenir des écosystèmes et des services écosystémiques importants dont la survie dépend de l'eau. Cependant, avec l'augmentation de la demande et de la concurrence pour l'eau, les ressources en eau de la planète ’ sont soumises à des pressions croissantes dues au changement climatique, à la mauvaise gestion et à la pollution
. L'agriculture détient la clé pour atteindre avec succès les objectifs et les aspirations énoncés dans : Les objectifs de développement durable et L'accord de Paris sur le changement climatique. elle est également cruciale pour les moyens de subsistance de centaines de millions de petits exploitants agricoles et de communautés rurales dans le monde.
Les agriculteurs doivent être au centre de tout processus de changement dans le domaine agricole. Grâce à des politiques appropriées qui offrent des incitations et garantissent une gouvernance efficace, les agriculteurs peuvent être habilités à conserver la biodiversité, à protéger les écosystèmes et à minimiser les impacts environnementaux.
