Africa disputes over land and maritime boundaries.

The creation and maintenance of National boundaries in Africa on land and sea is not always agreed upon since Africa straddles the equator, and is the second largest landmass on earth.

Dividing lines of land and sea boundaries in Africa’s 54 countries leads to disputes over land and maritime boundaries when money and safety are involved.

Stats and information in Africa disputes over land and maritime boundaries.

Clear property lines identify the land and sea boundaries belonging to a country but in many circumstances, these lines are blurred. Moreover, even when a permanent marker can be located and agreed upon the boundary dispute may not be settled for years.

Land boundary markers

In many cases, one African country accuses another of moving boundary markers or borders are porous leading to an influx of refugees. Boundary stones or markers are a physical marker that identifies the start of a land boundary or the change in a boundary.

Many African countries such as Liberia and Ghana have a government branch that oversees Lands Commission Act centered on Land Commission’s policy recommendations for land rights, the land sector is orderly, just, and contributes to economic growth and development. The Government is responsible for administering and managing land within the region in the public interest.

Maritime boundary lines

A maritime boundary is the water’s surface bounds areas of exclusive national rights over mineral and biological resources, encompassing maritime features, limits, and zones. Normally, a maritime boundary is set at a particular distance from a territory's coastline.

Maritime boundaries do not encompass lake or river boundaries, which are considered within the context of land boundaries. The outlining of maritime boundaries has financial and environmental implications in Africa.

eSwatini
In 2006, Swati king advocated resorting to ICJ to claim parts of Mpumalanga and KwaZulu-Natal from South Africa.

Both countries claim Isla Perejil Leila Island and discussions have not progressed on a comprehensive maritime delimitation, setting limits on resource exploration and refugee interdiction. Since Morocco's 2002 rejection of Spain's unilateral designation of a median line from the Canary Islands Morocco serves as one of the primary launching areas of illegal migration into Spain from North Africa.
