How big is Africa really? Why the UN voted to change the world map

The United Nations General Assembly has voted to back a resolution spearheaded by several African countries to adopt a map that shows the continent as much bigger than it is on conventional world maps.

On Friday, the resolution aimed at “a more accurate representation” of continental landmasses on the globe was supported by 164 countries, while the United States voted against it and six other states abstained.

The new map – known as the Equal Earth cartographic projection – “is a relevant option for improving the accuracy of the cartographic representation of the world”, the resolution stated.

Foreign Minister Robert Dussey of Togo, which drove the resolution, said maps “guide education, nourish the imagination, and influence collective perceptions”.

“The resolution adopted today reaffirms African reality,” he added.

But how does the new map differ from the traditional version, and why did the US object?

The UN has urged member states to adopt a new map in place of the centuries-old, traditional Mercator projection, which was designed for maritime navigation by Flemish cartographer Gerardus Mercator in 1569.

That projection focused on accurate depictions of the shapes and angles of land masses, but their relative sizes were often inaccurate – in part because of the challenge of rendering a three-dimensional globe onto a two-dimensional surface.
