Agro-forestry, cover crops and other practices that increase vegetation cover and enhance soil organic matter, carefully managed and varying by agro-ecosystem, mitigate climate change  . Global meta-analyses demonstrate agro-forestry as storing 20-33% more soil carbon than conventional agriculture  and reducing the spread of fire . Minimising synthetic inputs such as nitrogen- based fertilizers reduces emissions . Cover crops can reduce N2O emissions and increase soil organic carbon . Conservation farming  increases soil organic carbon, particularly in arid regions . Silvo-pastoral systems  and other practices that increase vegetation cover and enhance soil organic matter increase sequestered carbon in vegetation and soils . Agro-ecologically improved management of land for crops and grazing has significant mitigation potential, estimated at 2.8-4.1 GtCO2-eq yr1  .
