Out of the 48 African countries that are maritime nations and members of the International Maritime Organization, ten interestingly have very short coastlines that measure between 37km and 320km.

The Democratic Republic Congo with 37km has the shortest coastline not only in Africa but the entire world. Togo has a 56km coastline, Gambia 80km, Benin 121km while the Republic of the Congo can boast of a 169km long coastline.

Mauritius has a coast that is 177km long, Sao Tome and Principe 209km, Equatorial Guinea has 296km, Djibouti 314km, while Guinea is endowed with 320km.

The line that demarcates the region between the land and the ocean, a separating point that differentiates terrestrial environment and marine environment is the coastline.

Coastlines can expand or shrink depending on the state of the marine environment. Climate change issues like erosion, rising sea levels, and tidal waves are some threats/challenges such nations have to grapple with.

Nations with short coastlines are expected to live up to the responsibility of maintaining the sea levels in its natural state. Polluting the ocean can trigger storm tide, tsunami, wave overtopping, intense rainfall, increasing sea levels which affects the land since there is no much boundary between the land and sea.

Other adverse effects could include the sinking of lands leading to more loss of land and narrower coastline, and the washing off of the agricultural nutrients of lands belonging to countries.
