In a forest resource assessment of Ethiopia, Reusing found that within 17 years (1973–1990) high-forest cover decreased from 54,410 to 45,055 km² or from 4.72 to 3.96% of the land area. [5] He calculated a deforestation rate of 1,630 km² per year, which means that deforestation at the same rate would leave about 18,975 of the 45,055 km² in ...
Elsewhere, the land is subject to erosion, overgrazing, deforestation, and frequent droughts. Water shortages are common in some areas during the dry season. The causes of degradation are primarily the demand for more land for agriculture, fuel and construction as well as for grazing grounds.
For example, in Ethiopia the country has been affected by chronic and ongoing land degradation processes and forms. The major proximate drivers are biophysical factors and unsustainable land management practices, while the underlying drivers are social, economic, and institutional factors.
Coffee harvest in Ethiopia. Coffee, which originated in Ethiopia, is the largest foreign exchange earner. Agriculture accounted for 50% of GDP, 83.9% of exports, and 80% of the labor force in 2006 and 2007, compared to 44.9%, 76.9% and 80% in 2002–2003, and agriculture remains the Ethiopian economy's most important sector.

Soil degradation in this district became important when humans started deforestation almost 5000 years ago. [ 9 ] [ 10 ] Depending on land use history, locations have been exposed in varying degrees to such land degradation .
Hence, soil erosion is an important problem, which results in low crop yields and biomass production. As a response to the strong degradation and thanks to the hard labour of many people in the villages, soil conservation has been carried out on a large scale since the 1980s and especially 1980s; this has curbed rates of soil loss.
Soil degradation in this district became important when humans started deforestation almost 5000 years ago. [7] [8] Depending on land use history, locations have been exposed in varying degrees to such land degradation.
For many years, there has been severe land degradation and desertification in Tigray and the area became also impoverished; however, a lot of efforts are done to rehabilitate these semi-arid mountain landscapes. [2] Since 1994, researchers, students, and field assistants have studied the environment of Dogu’a Tembien.
