Africa is much bigger than most maps show, and a new campaign wants that fixed

The Brief

• African advocacy groups launched a campaign to replace the Mercator map with the Equal Earth projection.

• The African Union endorsed the effort, saying the distorted map minimizes Africa’s global importance.

• Experts say the Mercator projection, created for navigation centuries ago, has little use today.

On most world maps, Greenland and Africa look about the same size. In reality, Africa is so large that at least 14 Greenlands could fit inside it.

That distortion, common on the widely used Mercator projection, is driving a campaign led by African advocacy groups and now backed by the African Union. Supporters say the way Africa is shown on maps affects how the world sees the continent of more than 1.4 billion people.

Africa appears too small on most modern maps

The backstory

The Mercator map was created in the 16th century by Flemish cartographer Gerardus Mercator. It was designed to help sailors maintain straight-line courses at sea, but it also distorted the scale of landmasses — inflating areas near the poles and shrinking regions closer to the equator.

That means continents such as Africa and South America appear far smaller than they really are, while Greenland and Europe look larger.

By contrast, the Equal Earth projection, introduced in 2018, follows the planet’s curvature and shows continents in their correct proportions. But the Mercator projection is still common in classrooms and digital platforms. Google Maps switched to a 3D globe view on desktop in 2018, though the mobile app still defaults to the Mercator projection.

Groups campaign to replace the global map

The other side

Two African advocacy groups, Africa No Filter and Speak Up Africa, launched the “Change The Map” campaign in April. Their goal is to persuade schools first, then international organizations and media outlets, to adopt the Equal Earth projection.

Fara Ndiaye, co-founder and deputy executive director of Speak Up Africa, told the Associated Press the issue is about more than Africa alone.

“Correcting the map is not only an African issue. It is a matter of truth and accuracy that concerns the entire world,” Ndiaye said. “When whole generations, in Africa and elsewhere, learn from a distorted map, they develop a biased view of Africa’s role in the world.”

Ndiaye added that when non-Africans see a smaller version of the continent, it “minimizes its demographic, economic and strategic significance.”

The African Union, a 55-member diplomatic body, endorsed the campaign on Aug. 14. It is the largest organization to sign on so far, and advocates called the move a milestone in the effort to reshape how Africa is represented globally.

Geographers say the Mercator projection is outdated

What they’re saying

Mark Monmonier, a geography professor at Syracuse University, told the AP that the Mercator projection no longer has practical use.

“It was a useful navigation tool in the 16th century, because it has straight lines, giving navigators a line of constant direction to sail along,” Monmonier said. “But outside of that very narrow navigation application, there is no point in using it.”

Monmonier said even newer map projections have limits, because landmasses are irregularly shaped. “When you put irregularly shaped areas on a flat paper, people are going to have a hard time accurately comparing the size of landmasses,” he said, adding that bar graphs are often a better way to compare continent sizes.
