The specific objective of the present work is to perform a meta-analysis study evaluating greenhouse gases emission in livestock systems. The main greenhouse gases due anthropogenic activities are carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O). The global warming potential of N2O is 298 times higher than CO2. Moreover the N2O is the main substance depleting ozone layer in this century. The agriculture sector is the main contributor of N2O, in which the livestock systems correspond to 40% of total N2O emitted in agriculture due animal manure deposition on soil. The present work aim to understand the N2O emissions from livestock systems, related to climate, soil properties and management. Moreover will be possible to quantify the reduction in N2O emissions due better practices, aiming to improve sustainability metrics of livestock production.
