Climate change in Ethiopia is affecting the people in Ethiopia due to increased floods, heat waves and infectious diseases. [4] In the Awash basin in central Ethiopia floods and droughts are common. Agriculture in the basin is mainly rainfed (without irrigation systems). This applies to around 98% of total cropland as of 2012.
At the beginning of the twentieth century around 420,000 square kilometres (35% of Ethiopia's land) was covered by trees but recent research indicates that forest cover is now less than 14.2% due to population growth. Despite the growing need for forested lands, lack of education among locals has led to a continuing decline of forested areas.
Climate change is of great concern in Ethiopia, especially since the 1970s. Between the mid-1970s and late 2000s, Ethiopia's rainfall in some areas and seasons decreased by 15-20 percent. Furthermore, numerous studies predict climate change will increasingly affect the country's ecosystem, causing drought and famines.
The 1977 famine also provided an impetus to promote conservation. The government mobilized farmers and organized "food for work" projects to build terraces and plant trees. During 1983-84 the Ministry of Agriculture used "food for work" projects to raise 65 million tree seedlings, plant 18,000 hectares of land, and terrace 9,500 hectares of land.
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.
The Ethiopian montane forests is a tropical moist broadleaf forest ecoregion in Ethiopia. It covers the southwestern and southeastern portions of the Ethiopian Highlands. The ecoregion includes distinctive Afromontane evergreen forests. The ecoregion's biodiversity is threatened by deforestation, conversion to agriculture, and overgrazing. [2]
While the Green Revolution had ensured the growth of overall crop production per land area of 250% to 300% since the 1960, [5]: 727 with around 44% attributed to newer crop varieties alone, [131] it is believed this growth would have been even greater without the counteracting role of climate change on major crop yields over the same period ...
Deforestation, and conversion of grasslands to desert, may also lead to cooling of the regional climate. This is because of the albedo effect (sunlight reflected by bare ground) during the day, and rapid radiation of heat into space at night, due to the lack of vegetation and atmospheric moisture. [18]
