This map provides an overview of the potential impact of climate change on agriculture over 12982 subcatchments. It is measured in the change of annual plant growth days. Green indicates an increase of plant growth days due to fewer days of water stress and/or fewer days of temperature stress (positive potential impact). Red indicates a decrease of plant growth days due to more days of water stress and/or temperature stress (negative potential impact). The potential impact is very heterogeneous across the Black Sea catchment. The adaptive irrigation capacity and the total agriculture vulnerability is also made available in this dataset.
