چکیده

Background and objective: Spatiotemporal maps are suitable tools to convey information to the interested audience. The aim of this paper is to create continent-wide spatiotemporal maps regarding the role of agriculture on CO₂-eq production in the period between 1990 and 2019 using the t-map package of R software.
Materials and methods:  Initial data were obtained from the Internet resources (the FAO, and ARCGIS websites), and after performing some adjustments and modifications i.e. deletion of unnecessary data and matching of the contents of the FAO and ARCGIS data files, as well as combining data files, final data were uploaded to the R software to convert to spatiotemporal maps using the t-map package.
Results and conclusion: The results showed a decreasing trend of the share of agriculture in total CO2-eq production from 1990 to 2019. At the same time, the amount of agriculture-induced CO₂-eq has increased very gradually. On the other hand, the amount of total CO₂-eq produced has grown considerably from 1990 to 2019; therefore, it can be concluded that the growth of CO₂-eq production in the other economic sectors is higher than that of agriculture. Thus, the first priority should be to curb the growth of CO₂-eq production in all economic sectors, especially non-agricultural ones.
