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 campaignsSettlements
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 * TsadqaneAgriculture and livelihood
The population lives essentially from crop farming, supplemented with off-season work in nearby towns. The land is dominated byfarmland

History
The history of the ''tabia'' is strongly confounded with thehistory 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 * Mebrahten Gebremeskel at Aregen * Letebrhan Gebrekidan at KelkelayRoads and communication
The main road Mekelle – Hagere Selam –Abiy Addi
Abiy Addi (also spelled Abi Addi; Tigrigna ዓብዪ ዓዲ "Big town") is a town in central Tigray Region, Tigray, Ethiopia. Abiy Addi is at the southeastern edge of the Kola Tembien woreda, of which it is the capital.

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.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 bottomTrekking 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. * 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” caveAccommodation and facilities
The facilities are very basic. 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.See also
