Abstract

Eritrea is a country with rich gold, silver and base-metal deposits and geothermal energy resources associated with all the fivevolcanoes located within the Danakil graben. Due to low rainfall, the country has to depend on imported food and food importshave crossed > 46% in the recent years. Although the cultivable land is about 16,000 km2, only 5030 km2land is being cultivateddue to insufficient water resources. The per capita water requirement is projected to fall below 1300 m3/year from the present1470 m3/year. The country’s GDP has fallen from 1.3% in 2013 to 0.3% in 2015. Each geothermal province associated with theactive volcanoes can support to generate 445 million m3of desalinated water from the Red Sea. Providing basic needs like waterand energy will boost the country’s economy and lift the socio-economic status of 6 million people in the country.
