 Location and Size

The district has a total land area of about 755.37290 square kilometers (km2 ). It is located between latitudes 7o 35’ N and 7o 58’N and longitudes 2o 47’ W and 2o 78’W. It shares borders with the Jaman North District in the north, Berekum Municipal in the south-east, Dormaa Municipal in the south-west and La Cote d’Ivoire in the west.

Climate

The district lies within the wet semi-equatorial region, with a mean annual rainfall ranging between 1,200 -1,780mm and a double maxima rainfall pattern. The district has its major rainy season from April to June while the minor rains are from September to October. The month of August experiences a short dry season, with the prolonged one in the months of December to March. The average annual temperature is about 25°C. Relative humidity is also generally high between 70 percent and 80 percent during the rainy season.

Vegetation

There are two major types of vegetation in the district. These are the semi-deciduous forest and savanna woodland. Parts of the original semi-deciduous forest have become secondary type of vegetation as a result of extensive lumbering and agricultural activities. This secondary type of forest is made up of shrubs and grasses with few original tree species of Odum, Wawa and Mahogany. The savanna woodland is located at the northern part of the district where it shares boundaries with the Jaman North district and parts of La Cote d’Ivoire. It is characterized by elephant grass, shrubs and a few scattered trees ranging between 14m to 27m high.

Drainage

The drainage pattern of the Jaman District is largely dendritic which flows in a north-east and southern directions. Most of the rivers flow from the northern end of the district with a few 2 of them including Atuna, Fetenta and Ntabene having their sources from southern Berekum and Dormaa districts.

 Soils, Geology and Minerals

There are three main categories of rocks and two soil types which underlie the district namely; Birimian, Buem and Dahomeyan rocks. Considering these rock types, the Birimian rocks are the mineral bearing rocks. Minerals found in the district include: Gold at Yaamiasa, Atuna and Adamsu. The Birimian rocks hold the potential for exploitation of gold, diamond and other precious stones. Though these mineral deposits have been identified in the district, mining activities are yet to be undertaken. The District Assembly is in the process of giving out concessions. Clay deposits have also been reported at Dwenem.

The district is largely characterized by soils developed over the Birimian and Buem series. The geological features together with vegetation influence give rise to two distinct soils. These are the forest Ochrosols and the savanna ochrosols. Substantial clay deposits which could be developed into ceramics can also be found in parts of the District, notably around the Beahu area.

The combination of these underlying rocks has resulted in the formation of different soil types which support different agricultural production. For example, moderately well drained clayey loam type of soils is very good for the production of cashew, cocoa, citrus, oil palm and food crops; loamy sand soil type support the production of maize, vegetables and legumes; silky clay soil type is good for the production of maize, vegetables, legumes, and sugar cane, and clay soil, good for the production of vegetables sugar cane and rice.
