Some agricultural practices that people in low-income countries use to maintain or improve their food security also emit greenhouse gases. In many low-income countries, particularly in Sub-Saharan Africa and Latin America, most increases in agricultural output have stemmed from area expansion as mentioned above. Shortened fallow periods and other practices also lead to land degradation. Both the conversion of natural vegetation to cropland or pasture and the degradation of land lead to the emission of formerly sequestered carbon into the atmosphere.
