Plain landforms are of great importance in the agricultural sector. This is because, the sediments which makeup the various types of plain landforms contribute immensely to fertility, thereby facilitating excellent crop growth and grasslands which provide good grazing for livestock. Also, the approximate flatness of the various plain landforms facilitates mechanization of crop production.
Population and settlements are usually concentrated on plains. This is because, towns are easily laid out on the approximately flat landform found on plains. The landform could be of great economic importance when traversed by rivers. Such plain landforms traversed by rivers make irrigation of farmlands on plains much easier than on any other land form used in agriculture.
Plain landforms such as alluvial terraces attract good settlements and populationconcentration because of the advantage it offers over valley-bottom flood plains which is usually subject to annual or periodic flooding and hill slopes which may be too steep and rocky to cultivate.
Plain landforms are excellent for sporting activities as they provide a levelled ground for sports and other recreational activities.
Plains provide good communication routes such as railways, roads, airports
Plains are good sources of mineral resources such as Coal, Tin and Petroleum
