Growth

The salt lake has grown significantly in the past 50 years, growing from 3 square kilometres (740 acres) in 1957 to 42.6 square kilometres (10,500 acres) in 2008. The lake is growing to the east and northeast due to the local topography.[1]

Impact

Agriculture

Due to the growth of the lake, there is an increasing concern that it will permanently damage the nearby Awash River, which is a major water source for nearby cotton and sugar plantations. These crops have significant economic importance to the region and the whole of Ethiopia.[2] The salinity of the lake is 10.7 dS/m. The water salinity is also affecting the area groundwater as the salinity levels have increased in most plantation sections,[1] and local sugar refineries have reduced production rates due to the loss of growing area.[3]

Population

In 2011, a school succumbed to the growing level of the lake.[2] Highway number 4, the main route between Addis Ababa and Djibouti has a permanent detour that has been constructed since the old highway is submerged. Homes have also been lost due to the expansion.[3] It has been predicted that in 20–30 years, the town of Metehara will be displaced along with 21,000 citizens.[1]
