World map needs ‘correcting’ to show Africa’s true size, say campaigners

A campaign group is pushing to have the current world map "corrected" to show Africa is actually larger than the current Mercator projection.

On the Mercator projection, one of the world’s most popular maps, Greenland and Africa appear to be about the same size. But on the Equal Earth projection showing continents in their true proportions, 14 Greenlands would easily fit inside the African continent.

Criticism that the Mercator projection does not accurately reflect Africa’s real size is not new.

However, a recent campaign by African advocacy groups is gaining momentum online as it urges organizations and schools to adopt the Equal Earth projection, which they say more accurately displays the size of the continent of more than 1.4 billion people.

The African Union, the continent’s diplomatic organization with 55 member countries, endorsed the campaign last week in what advocates call a major milestone.

Here is what to know about the effort to show Africa’s real size to the world.

Africa appears too small on most modern maps.

The Mercator map was created in the 16th century by Flemish cartographer Gerardus Mercator. Designed to help European navigators at sea, the map distorted landmasses by enlarging regions near the poles such as North America and Greenland while shrinking Africa and South America.

The 2018 Equal Earth projection is a modern map that follows the Earth’s curvature and shows continents in their true proportions, unlike the distorted Mercator map.
