Aregen is a tabia or municipality in the Dogu'a Tembien district of the Tigray Region of Ethiopia. The tabia centre is in Addi Gotet village, located approximately to the west-southwest of the woreda town Hagere Selam.
Geography
The tabia occupies an elongated ridge between the gorges of Upper Tanqwa and Tsech'i Rivers. The highest peak is near Aregen village and the lowest place at the confluence of the two rivers.
Geology
From the higher to the lower locations, the following geological formations are present:
** shallow, dry soils with very high amounts of stones
** deep, dark cracking clays with good fertility, but problems of waterlogging
** soils with stagnating water due to an abrupt textural change such as sand over clay
Climate
The rainfall pattern shows a very high seasonality with 70 to 80% of the annual rain falling in July and August. Mean temperature in Addi Gotet is 18 °C, oscillating between average daily minimum of 10 °C and maximum of 25.7 °C. The contrasts between day and night air temperatures are much larger than seasonal contrasts.
Springs
As there are no permanent rivers, the presence of springs is of utmost importance for the local people. The main spring in the tabia is Gubarne in Kelkelay.
Reservoirs
In this area with rains that last only for a couple of months per year, reservoirs of different sizes allow harvesting runoff from the rainy season for further use in the dry season.
Traditional surface water harvesting ponds, particularly in places without permanent springs, called rahaya
Horoyo, household ponds, recently constructed through campaigns
Settlements
The tabia centre Addi Gotet holds a few administrative offices, a health post, a primary school, and some small shops. There are a few more primary schools across the tabia. The main other populated places are:
Kelkelay
Mahba
Geshere
Aregen
Tsadqane
Agriculture and livelihood
The population lives essentially from crop farming, supplemented with off-season work in nearby towns. The land is dominated by farmlands which are clearly demarcated and are cropped every year. Hence the agricultural system is a permanent upland farming system. The farmers have adapted their cropping systems to the spatio-temporal variability in rainfall.
History and culture
Caves and archaeological sites
The Dabo Zellelew cave at the west of Aregen at a height of about 2000 metres, has been explored over 14.4 m but its distance is claimed to be way longer. It contains lithic tools, potsherds, engravings and paintings of Pastoral Neolithic age. The Mihdar Ab’urcave in the village of Mahba at a height of about 2500 metres, is some 64 m long. It contains engravings and paintings of Pastoral Neolithic age.
History
The history of the tabia is strongly confounded with the history of Tembien.

Its mountainous nature and proximity to Mekelle makes the tabia fit for tourism.
Geotouristic sites
The high variability of geological formations and the rugged topography invites for geological and geographic tourism or "geotourism". Geosites in the tabia include:
the “vase cave” in the gorge down from Tsadqane
the wider Ruba Dirho area, densely vegetated in the valley bottom
Trekking routes
Trekking routes have been established in this tabia. The tracks are not marked on the ground but can be followed using downloaded.GPX files.
