Abstract
The objective of this research was to estimate greenhouse gas emissions from livestock in Cuba in the period 1990-2020. The methodology used is based on the 2006 IPCC Guidelines. CH4 emissions were estimated for the Enteric Fermentation subcategory, and CH4 and N2O emissions for the Manure Management subcategory. The activity data were obtained from the Annual Statistical Yearbooks published by the National Office of Statistics and Information. Characteristic parametric data of bovine livestock in the country were available, provided by the Ministry of Agriculture. These data made possible to calculate, for each type of cattle, country-specific emission factors and the annual average nitrogen excretion, to estimate CH4 emissions from Enteric Fermentation and Manure Management, and N2O emissions from Manure Management, respectively. Default emission factors from the 2006 IPCC Guidelines were used for the remaining species. Emissions for both subcategories in 2020 decreased with respect to the 1990 base year, as a consequence of reduced livestock populations. Enteric fermentation was the most relevant subcategory with 81.2% of greenhouse gas emissions from the Livestock category. Cattle constituted the only significant subcategory of emissions from Enteric Fermentation and Manure Management.
