The elevations of this woreda range from 750 to 2800 meters above sea level; about 23% is classified lowland, 63% mid-level, and 23.7% uplands. Rivers and streams include the Futan. The topography of Tach Gayint is distinguished by gullies and rugged terrain covering 54% of its surface, while mountains cover 23% and plains 22%. Above all a significant portion of the arable land is degraded. Deforestation is a serious problem in Tach Gayint, and it has been increasing rapidly. Once all of the trees had been cut for firewood, locals then turned to extracting the roots, which has critically damaged the soil in this woreda. As Sileshi Tessera writes in his study, "Tach Gayint has been virtually stripped of vegetation." A sample survey reveals that the total area of berha is 31,386.37 hectares, common grazing land is 8,107.11 hectares and of wojed is 46,174.03 hectares. The major agricultural crops in Tach Gayint include: cereals such as teff, barley and wheat ; pulses such as fava beans, field peas, haricot beans, and chick peas ; vegetables such as potatoes ; bananas and hops. Due to the extreme poverty endemic in this woreda, Sileshi Tessera noted the importance of local social institutions, which redistributes food to needy members. The most important – and popular – is the iddir, which was adopted in Tach Gayint only six or seven years before Sileshi's study. Other social institutions present include the mahiber, iqqub, and the sebeka-gubae; the last two also provides cash funds to needy members. On the other hand, modern assistance institutions, for example microfinance programs, have proven less successful.
