Geography
The ''tabia'' occupies the flanks of the valley of the
Tsech'i River
The Tsech'i is a river of the Nile basin. Rising in the mountains of Dogu’a Tembien in northern Ethiopia, it flows westward to empty finally in Giba and Tekezé River.
Characteristics
It is a confined ephemeral river, locally meandering i ...
that drains Dogu'a Tembien to the west. The highest peak is near Welekhlekha (almost 2700 m a.s.l.) and the lowest place in the lower Tsech'i gorge (1920 m a.s.l.).

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 xxx is 17.4 °C, oscillating between average daily minimum of 9.6 °C and maximum of 24.8 °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 Gfay
* May Tsechi
* Gigbana
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 Bayro 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:
* Welekhlekha
* Tsech'i
* Gulha
Agriculture and livelihood
The population lives essentially from crop farming, supplemented with off-season work in nearby towns. The land is dominated by

History
The history of the ''tabia'' is strongly confounded with the history of Tembien

Religion and churches
Most inhabitants are Orthodox Christians. The Gulha Maryam church with its large forest is located in the ''tabia''.
''Inda Siwa'', the local beer houses
In the main villages, there are traditional beer houses ('' Inda Siwa'').

makes the ''tabia'' fit for tourism. The high variability of geological formations and the rugged topography invites for geological and geographic tourism or "geotourism".
Trekking routes 7 and 19 pass along the southern ridge in this ''tabia''. The tracks are not marked on the ground but can be followed using downloaded .GPX files. They link Inda Maryam Qorar to Debre Sema'it rock church.
Facilities in Menachek are very basic.
