Accra Plains

The Accra Plains are a region in southeastern Ghana, characterized by anomalously low annual rainfall, with figures ranging from less than 30 to 40 inches (760 to 1,000 mm). This area experiences precipitation variability and vegetation similar to the northern savanna zone. The plains are underlain by ancient Precambrian rocks, primarily gneisses, with some areas rising as inselbergs.12

The Accra Plains are part of the coastal savanna zone, which contains various soil types, including tropical black earths known as Akuse clays. While these clays can be challenging to work with, they are suitable for agriculture when irrigated and mechanically cultivated. The region's soils are generally dependent on humus from vegetation for fertility, making the balance between vegetation and soil health crucial. The susceptibility of the area to faulting can also lead to occasional earthquakes.324
