Climate and hydrology


Climate and meteorology

Average annual precipitation (in Hagere Selam) is 778 mm. Mean temperature is 13.3 °C, oscillating between average daily minimum of 10.9 °C and maximum of 22 °C. As it is common at tropical latitudes, the contrasts between day and night air temperatures are much larger than seasonal contrasts. The rainfall pattern, however, shows a very high seasonality with 70 to 80% of the annual rain falling in July and August. The annual seasons are "hagay" (dry season in winter), "belgi" (spring rains), "kremti" (main summer rains) and "qew'i" (autumn), when the crops are ripening off. In the summer rainy season the dominant wind direction is from the southwest, whereas in the rest of the year winds blow from the east. The farmers have adapted their

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; this has curbed rates of soil loss. Measures include the construction of infiltration trenches, stone bunds, check dams, small reservoirs such as Chini and May Leiba as well as a major biological measure:

An average family owns one or two oxen (six or eight for a rich family), one to three cows with their calf(s) (ten), 5 to 7 goats or sheep (20 or 30), and sometimes a donkey (three or four mules and donkeys for a rich family). Livestock are mainly a source of energy, hence they are part of the permanent farming system: oxen are

, particularly towards remote and vast grazing grounds * daily movements with livestock back-and-forth to the grazing grounds, the "home range herders" – they travel back and forth daily to grazing grounds that are a few kilometres away * keeping livestock nearby to the homesteads In some villages most people with not practice transhumance, but even in villages which practice transhumance, some will prefer using the nearby grazing grounds. If the grazing lands are far from the village, deep in the gorge, livestock will stay there overnight (transhumance) with children and a few adults keeping them. Some examples: * The cattle of Addi Geza’iti (2580 m) are brought every rainy season to the gorge of River Tsaliet (1930 m) that holds dense vegetation. The cattle keepers establish enclosures for the cattle and places for them to sleep, often in rock shelters. The cattle stay there until harvesting time, when they are needed for threshing, and when the stubble becomes available for grazing. * Many cattle of Haddinnet and also Ayninbirkekin tabias are brought to the foot of the escarpment at Ab’aro, with all herds passing through Ksad Azef pass. Cattle stay on there on wide rangelands. Some cattle keepers move far down to open woodland and establish their camp in large caves in sandstone.

Rural sociology


Cattle ownership

Cattle, and particularly oxen, traditionally have social, economic and insurance value. This has contributed to wealth differentiation, structuring debts and management of the households.


Gendered division of labour

The ox-plough based agriculture, which has characterised Dogu’a Tembien since thousands of years, not only has shaped the agricultural landscape; it also forms the basis of social relationships. There is for instance a gendered

Culture


Music and festivals

* Just like Kola Tembien, Dogu'a Tembien is known for the frenetic ''Awrus'' dancing stylePhilip Briggs, ''Ethiopia: The Bradt Travel Guide'', 3rd edition (Chalfont St Peters: Bradt, 2002), p. 270 * Yearly there is the girls’ festival Ashenda. Then, young women dominate the public space with dances and songs which is in strong contrast with the rest of the year. The rural ‘’Ashenda’’ is very different from the "standardised" urban festival. * Also in summer, there is the boys’ festival Hawariat, where they clack whips. This lasts for about a week.

The brew is allowed to ferment for a few days, after which it is served, sometimes with the pieces of bread floating on it (the customer will gently blow them to one side of the beaker).

''Siwa'' is consumed during social events, after (manual) work, and as an incentive for farmers and labourers. There are about a hundred traditional beer houses ('' Inda Siwa''), often in unique settings, all across Dogu'a Tembien.
