The bilateral project GAtES (German-Armenian Network on the Advancement of Public Participation GIS for Ecosystem Services as a Means for Biodiversity Conservation and Sustainable Development) between the University of Hohenheim and the Acopian Center for the Environment of the American University of Armenia aims on broadening awareness of aforementioned issues within the local population and decision-makers of Armenia. Until today, basic data on e.g. rural energy use patterns or LULC which focuses on the Getik River Basin in the northeast of Armenia are published (Harutyunyan et al. 2019a; Harutyunyan et al. 2019b; Harutyunyan et al. 2019c). The present study proceeds on this work and takes on the question of where potential afforestation in the area could be realized and how it could develop. With regard to the NDC of the country of nearly doubling its forest area, the objective of the present paper is to provide a possible future scenario for afforestation within the Getik River Basin in Armenia and show its potential greenhouse gas (GHG) mitigation.
