Impact of Climate Change on Agro-Climatic Characteristics and Zones of Mtskheta-Mtianeti Region

Abstract

The temporal change tendency of agro-climatic characteristics for the vegetation period in the Mtskheta-Mtianeti region has been revealed taking into account climate change; In particular, the vegetation period prolongation in the arid subtropical, mountainous and highland zones of the region and the increase of the active temperature sum (>10°C), and the decrease dynamics of atmospheric precipitation (mm) and hydrothermal coefficient (HTC). According to the current (basic) and future scenarios (2020-2049), agro-climatic zones are allocated taking into account the temperature increase by 2°C, with recommendations for the spread of appropriate perspective crops by the height above the sea level. The forecast equation for the potato crop is drawn according to the temperature of the latter scenario. It is established that according to the future scenario (2020-2049), the increase of the projected temperature by 2°C will not have a negative impact on agricultural crops.
