POSITION, SIZE AND STRUCTURE
The Brong Ahafo Region is one of the ten regions of Ghana. It lies
within longitude 0° 15'E to 3° W and latitude 8° 45"N to 7° 30'S. The
Region shares common boundaries with five others - Northern Region to
the North, Ashanti and Western Regions to the South, the Volta Region to
the East and the Eastern Region to the South East. It has an
international boundary to the West which it shares with La Côte
It is the second largest Region in Ghana and has an area of 39,557 sq.
km. The region is divided into 19 administrative districts.
The relief is as follows: the southern and eastern parts have rather low
elevations not exceeding 152.4m (500ft) above sea level. The land then
gradually rises towards the north around Techiman, where it attains a
height of 533.7m (1751ft) in the Buoyem hill. Other higher elevations
occur at Bosumkese 712.6m (2338ft) and Bonsam 643.1m (2110ft). Sunyani
has an average elevation of about 384.8m (1000ft). Along the Côte
d'Ivoire border the land rises at certain places, for instance, Asuakwaw
483.7m (1587ft) Sampa 457.5m (1501ft) and Banda 592.2m (1943ft).
Two main drainage systems could be distinguished in the Region. The
Black Volta dominates the Northern parts of the Region, while to the

along the Western border of the Region, the average annual rainfall is
about 1143-1270 mm (45-50 inches). Rainfall in the northern parts of the
Region is lower than these values.
The predominant vegetation zones are the moist semi-deciduous forest to
the South and South West and the Guinea Savannah Wood in the eastern
half of the northern third of the region.
Reserved forests are virtually confined within the moist semi-deciduous forest zone, especially to the South West of Sunyani.
