Les agriculteurs de nombreuses régions du monde, en raison de la croissance démographique, n'ont guère d'autre choix que de cultiver en permanence leurs terres, avec des ressources limitées pour remplacer les nutriments retirés par chaque culture successive. Les résidus de cultures, source de matière organique et de paillis, sont souvent perdus généralement par brûlis ou utilisés comme fourrages pour le bétail élevé hors de la parcelle ou comme combustible de cuisson. En particulier lorsque les réserves en nutriments sont déjà faibles et que la terre arable est exposée à l'érosion, les sols perdent leur capacité à maintenir des rendements adéquats des cultures. De plus, les événements météorologiques extrêmes, les changements climatiques défavorables, les conflits humains et la maladie peuvent tous affecter la capacité des petits exploitants agricoles ’ à maintenir la capacité de production de leurs sols. L'agriculture de conservation tente de résoudre ces problèmes

.

L'agriculture de conservation (AC) est une approche de gestion des terres qui vise à préserver les ressources tout en optimisant et soutenant la capacité des sols à produire de la nourriture. Dans l'AC, la durabilité est liée à la préservation écologique des paysages agricoles. Cela se fait par 1) une perturbation minimale du sol, 2) le maintien des sols sous couvert et 3) la diversification des cultures. La mise en œuvre de ces trois éléments nécessite une combinaison de pratiques, pour lesquelles il existe de nombreuses options. Le fait de considérer l'AC comme un système global, plutôt qu'un ensemble fixe de techniques, offre aux agriculteurs et aux praticiens la liberté d'évaluer et d'adopter un ensemble de pratiques liées à l'AC adaptées aux besoins locaux
