The high fertility of the lands shown on the map can typically be attributed to rich soil composition, ample rainfall, and favorable climate conditions. Additionally, the presence of organic matter from decomposed vegetation and nutrient-rich sediments from river deposits can enhance soil fertility. These factors create an optimal environment for agriculture and plant growth.
Every year heavy summer rain in the Ethiopian highlands sent a torrent of water that caused the Nile to flood. When the floods receded a thick rich mud (black silt) was left and this was excellent soil to plant in. So this area was known as the Black Land and further away from the river was the Red Land, a region of inhospitable desert.
