At the beginning of November 2020, an armed conflict emerged in Tigray, Ethiopia���s northernmost region. The objective of this ���Atlas of the Humanitarian Situation��� is to document and map the situation in which approximately 6 million Tigrayans currently find themselves. For this, we contacted key informants in different districts of Tigray to collect qualitative and quantitative evidence of the actual situation on the ground. We also confronted these data and testimonies with information disclosed by the Government of Ethiopia and by humanitarian organisations. The 26 maps in this atlas provide detailed information at the scale of districts (woredas) or sub-districts (tabiyas). Besides background information related to administrative divisions, social and natural resources - locations of internally displaced people, massacres and civilian casualties receive due attention. Humanitarian access and needs are particularly addressed; official data on humanitarian aid distribution are mapped, and contrasted to ground evidence related to such distributions. The final outlook, links up the emergency and famine conditions in Tigray to the current crop status and to the blockade and siege of the region.
