From Ekli Imba down to the cliff that marks the boundary to Ayninbirkekin, “red-black” Skeletic Cambisol–Pellic Vertisol catenas occur on basalt.
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 Arebay is 17.2 °C, oscillating between average daily minimum of 9.5 °C and maximum of 24.6 °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 springs in the tabia are:
May Deqqi Sa’iri
Addi Amdey
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. Overall they suffer from siltation. Yet, they strongly contribute to greening the landscape, either through irrigation or seepage water. Main reservoirs are:
May Leiba reservoir, in Ayninbirkekin tabia; it intercepts the runoff from the southern half of Arebay
Traditional surface water harvesting ponds, particularly in places without permanent springs, called rahaya
Horoyo, household ponds, recently constructed through campaigns
Settlements
The tabia centre Arebay 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:
Medayq
Addi Amdey
Harhar
Ts’arot
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
History
The history of the tabia is strongly confounded with the history of Tembien.

Roads and communication
The main road Mekelle – Hagere Selam – Abiy Addi runs some 5 km south, and down, of the tabia. There are regular bus services to these towns. Further, a mountain access road links most villages to the main asphalt road.
Tourism
Its mountainous nature and proximity to Mekelle makes the tabia fit for tourism. The high variability of geological formations and the rugged topography invites for geological and geographic tourism or "geotourism".
can be done particularly in exclosures and forests. The Maryam Addi Amdey church forest is recommended.
