Geography

The tabia occupies an elongated ridge between the gorges of Upper Tanqwa and Tsech'i Rivers. The highest peak is near Aregen village (2,660 m (8,730 ft) a.s.l.) and the lowest place at the confluence of the two rivers (1,897 m (6,224 ft) a.s.l.).

Geology
View towards Aregen from the west - visible rock is Adigrat Sandstone

From the higher to the lower locations, the following geological formations are present:[1]

Geomorphology and soils

The main geomorphic units, with corresponding soil types are:[2]

  • Hagere Selam Highlands, along the central basalt and sandstone ridge
    • Associated soil types
    • Inclusions
      • Rock outcrops and very shallow soils (Lithic Leptosol)
      • Rock outcrops and very shallow soils on limestone (Calcaric Leptosol)
      • Deep dark cracking clays with very good natural fertility, waterlogged during the wet season (Chromic Vertisol, Pellic Vertisol)
      • Shallow stony dark loams on calcaric material (Calcaric Regosol, Calcaric Cambisol)
      • Brown loamy soils on basalt with good natural fertility (Luvisol)
  • Adigrat Sandstone cliff and footslope
    • Associated soil types
      • complex of rock outcrops, very stony and very shallow soils ((Lithic) Leptosol)
      • shallow, stony sandy [[loam soils (Eutric Regosol and Cambisol)
    • Inclusions
      • shallow, dry soils with very high amounts of stones (Leptic and Skeletic Cambisol and Regosol)
      • deep, dark cracking clays with good fertility, but problems of waterlogging (Chromic and Pellic Vertisol)
      • soils with stagnating water due to an abrupt textural change such as sand over clay (Haplic Planosol]])

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.[3]

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.[4]

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[5]

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:[6]

  • 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.[7] The farmers have adapted their cropping systems to the spatio-temporal variability in rainfall.[8]

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 (13.621862°N 39.033077°E / 13.621862; 39.033077). It contains lithic tools, potsherds, engravings and paintings of Pastoral Neolithic age. [9][10]

The Mihdar Ab’ur cave in the village of Mahba at a height of about 2500 metres, is some 64 m long (13.620592°N 39.051313°E / 13.620592; 39.051313). It contains engravings and paintings of Pastoral Neolithic age. [9]

History

The history of the tabia is strongly confounded with the history of Tembien.

Religion and churches

Most inhabitants are Orthodox Christians. The following churches are located in the tabia:

  • Mahba Mika’el
  • Aregen Maryam
  • Medhanie Alem
  • Tsadqane Maryam

Inda Siwa, the local beer houses

In the main villages, there are traditional beer houses (Inda Siwa), often in unique settings, which are a good place for resting and chatting with the local people. Most renown in the tabia are[4]

  • Mebrahten Gebremeskel at Aregen
  • Letebrhan Gebrekidan at Kelkelay

Roads and communication

The main road Mekelle – Hagere Selam – Abiy Addi runs just east of the tabia. In Maygua there are regular bus services to these towns. Further, a rural access road links Addi Gotet to the main asphalt road.

Tourism

Its mountainous nature and proximity to Mekelle makes the tabia fit for tourism.[11]

Geotouristic sites

The high variability of geological formations and the rugged topography invites for geological and geographic tourism or "geotourism".[12] 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.[13] The tracks are not marked on the ground but can be followed using downloaded .GPX files.[14]

  • Trek 6, follows the Ruba Dirho/Upper Tanqwa gorge, along the northern side of Aregen
  • Trek 7, allows to visit the eastern part of Aregen
  • Trek 20, in the Zeleqwa gorge, passes by the “vase” cave

Accommodation and facilities

The facilities are very basic.[15] One may be invited to spend the night in a rural homestead or ask permission to pitch a tent. Hotels are available in Hagere Selam and Mekelle.

gollark: Why's the UN not sending a *lot* of uploads instead of a huge crew of physical people?
gollark: You know, we have loads of minerals now, we could have lots of quantum computers.
gollark: Oh, how is the research going?
gollark: There's an issue with blasting gigawatts of X-rays through the atmosphere, but I guess you could have a relay beam the power to the surface from the power/laser systems.
gollark: You can work out the power just from the acceleration and mass, I think.
