UN backs resolution to adopt maps showing Africa's true size

The United Nations General Assembly has voted to endorse a resolution calling for the adoption of maps that represent Africa's actual geographic dimensions. The move addresses a cartographic problem that has persisted for centuries: the Mercator projection, the map format that has dominated global classrooms, offices, and atlases since the 16th century, systematically misrepresents the size of continents and countries, with Africa bearing the most severe distortion.

The Mercator projection was designed by Flemish cartographer Gerardus Mercator in 1569 as a tool for navigation at sea. It solved a specific problem—it allowed sailors to plot straight-line courses on a flat surface—but it introduced a fundamental trade-off: accuracy in size and shape. The projection stretches landmasses as they move away from the equator, which means that continents in the Northern Hemisphere appear vastly larger than they actually are, while Africa, which straddles the equator, appears dramatically smaller than reality. Greenland, for instance, appears roughly the same size as Africa on a Mercator map, when in fact Africa is approximately 14 times larger.

This distortion has had consequences that extend far beyond the classroom. Advocates for the resolution argue that centuries of viewing Africa through a diminished cartographic lens has shaped how the continent is perceived internationally—as smaller, less significant, less developed. The visual representation of geography influences how people think about power, resources, and importance. When a map consistently shows Africa as a fraction of its true size, it reinforces a particular narrative about the world's hierarchy.

The resolution represents a formal acknowledgment by the United Nations that map projections are not neutral tools. They are choices, and those choices carry weight. By backing a shift toward projections that accurately depict Africa's true proportions, the General Assembly is signaling that how we represent the world matters. More accurate maps exist—the Equal Earth projection, the Gall-Peters projection, and others—but they have never achieved the ubiquity of Mercator, partly through institutional inertia and partly because Mercator became so embedded in how we think about geography that alternatives seemed strange.

The practical implications of this resolution remain to be seen. Changing how maps are displayed in schools, government offices, and digital platforms will require coordination across multiple sectors and countries. Educational curricula would need updating. Digital mapping services would need to offer alternatives. But the symbolic weight is immediate: the world's primary international governing body has declared that Africa deserves to be seen as it actually is, not as centuries of European cartography rendered it.

For African nations and their advocates, the resolution represents validation of a long-standing complaint about how the continent has been represented to the world. It is a small but meaningful step toward decolonizing how geography itself is understood and taught. Whether this resolution translates into widespread adoption of more accurate maps, or remains largely symbolic, will depend on how seriously institutions take the call to change a system that has worked, from certain perspectives, for a very long time.
