Concept:Rural settlements in developing African countries are described by their spatial layout and arrangement of houses.
Explanation:In most rural parts of developing Africa, villages are formed with houses built very close together in a cluster.
This clustered or grouped pattern is known as a nucleated settlement.
Farmers and their families often live in these compact villages for security, social interaction, and easier access to communal facilities such as water and markets.
Their farmlands are usually located outside the village, beyond the cluster of houses.
Such settlements do not generally possess dense transport systems, and they are not typically surrounded by satellite towns.
Dispersed settlements, where houses are scattered over a wide area, are less common in many African rural regions.
Therefore, the most accurate description of these rural settlements is that they are nucleated.
