Flooding in Eritrea is primarily caused by the Gash River and other rivers originating from the Ethiopian Highlands, such as the Atbara and Tekeze (also known as the Setit) rivers. [1] [2] Between 2003 and 2006, several flood events have occurred, resulting in fatalities, displacement, and damage to infrastructure and agriculture. [3] [4] Eritrea's climate is semi-arid, characterized by a main rainy season from June to September and a shorter rainy season from March to May. Heavy rainfall during these periods can cause river overflow, leading to flooding, particularly in low-lying areas. [5] [6]
In August 2003, the Gash River overflowed its banks in the western Gash Barka region of Eritrea, causing the worst floods in 40 years. [7] The resulting floods caused damage to crops, vegetation, and agricultural facilities in Teseney. [8] According to official reports, large areas of farmland were destroyed, and part of the road to Teseney was cut off. The floods were a result of unusually heavy seasonal rains. [9]
