Eritrea - Topography
The topography of Eritrea is dominated by the extension of the Ethiopian north-south trending highlands, descending on the east to a coastal desert plain and on the northeast to hills and on the southwest to flat-to-rolling plains. Approximately 4% of the land is arable. Natural resources include gold, potash, zinc, copper, salt, and fish. Frequent droughts, soil erosion, deforestation, and overgrazing all present environmental challenges.
