Assessment of carbon dioxide sequestration service: Case study of Ijevan state sanctuary (Tavush' region of Republic of Armenia)

The article presents the study results of the carbon dioxide sequestration and emission reduction ecosystem services in the newly formed Ijevan state sanctuary, located in the Tavush region of Republic of Armenia (RA). As an outcome of study we got that forest ecosystems of Ijevan state sanctuary sequestrated 440,7 metric t carbon and reduced 1568,27 metric t CO2 emission annually. It turns out that the value of carbon sequestration service by forest ecosystems equal to US $ 4407000 annually. With the removal of illegal logging the amount of sequestered of carbon can be increased by 10,95 metric tons. As an outcome the amount of carbon dioxide in the atmosphere will be reduced by 39.07 metric tons. The economic benefit will be an annual US $ 109.500 surplus of service.
