![]() ![]() Therefore less carbon dioxide is being released into the atmosphere compared to plantation agriculture, permanent planting of seasonal crops or other activities such as logging. In fact, it has been posited that these systems are excellent at carbon sequestration. Some researchers have argued that the above scenario is not necessarily true and that shifting cultivation does not contribute to global warming. Therefore, the net emission of carbon dioxide contributes to global warming and ultimately climate change. Unfortunately, the system is not usually in equilibrium because of either the shortening of the fallow period or the utilisation of the plot for another type of land use instead of leaving it in fallow, among other reasons. If the shifting cultivation system is in equilibrium, the released carbon dioxide should be re-absorbed by the regenerated vegetation when the land is left fallow. Shifting cultivation and climate changeīurning biomass to clear the land in this agrosystem results in releasing carbon dioxide and other gases into the atmosphere. In sub-Saharan Africa, however, there is a distinct dry season with 1-2 months of low rainfall. The rainfall in the Amazon basin in South America is more or less consistent throughout the year. In addition, these areas typically have high levels of rainfall and year-round humidity.
