deforestation since the
colonial period, which began in the late 19th century. The Highlands are at particular risk of deforestation and associated
soil erosion
Soil erosion is the denudation or wearing away of the Topsoil, upper layer of soil. It is a form of soil degradation. This natural process is caused by the dynamic activity of erosive agents, that is, water, ice (glaciers), snow, Atmosphere of Ea ...

Sahel are at particular risk of
desertification and frequent drought. The Highlands experience, as most tropical regions, two seasons; the rainy season (''kremti'') is from June–September while the dry season (''haggai'') is from September to June. The average temperature for
Asmara, which is above sea level, is approximately , but other places range from about .

Many believe that
forest cover in the Eritrean Highlands was as high as 30% but has since declined to 1%; however, others including Louise Latt have suggested that there has never been such a dramatic decline in forest cover.
The eastern edge of the Highlands falls off dramatically towards the

which causes two climatic systems to overlap. This region is oft noted for its perennial forest cover. This is also the region that Eritrea's
Merara coffee is grown.
The soil conditions in the Eritrean Highlands is also quite complex. The predominant soils are chromic, eutric, and calsic
cambisols of strong red colour. Other soils found in the highlands are
lithosols,
xerosols and
fluvisols.
