What's Happening?
The United Nations General Assembly recently passed a resolution encouraging countries to adopt the Equal Earth projection for world maps, which more accurately represents the relative sizes of continents. This non-binding resolution, sponsored by Togo
and supported by African nations, aims to correct visual distortions present in the widely used Mercator projection, where landmasses appear disproportionately larger the further they are from the equator. For instance, Africa, which is 14 times larger than Greenland, appears roughly the same size on a Mercator map. The resolution garnered 164 votes in favor, with six abstentions. Notably, the United States was the sole country to vote against the resolution, characterizing it as a 'radical ideological project.' This move by the UN seeks to promote a more truthful understanding of global geography, particularly in educational contexts, by highlighting the trade-offs inherent in depicting a spherical Earth on a flat surface.
Why It's Important?
The UN resolution and the U.S. opposition highlight a broader debate about how maps influence perception and can carry geopolitical implications. The Mercator projection, while practical for maritime navigation due to its preservation of shapes and directions, distorts the sizes of landmasses, potentially leading to misperceptions about the relative importance or scale of different regions. The visually inflated size of certain landmasses, such as Greenland, on Mercator maps has been shown to influence public opinion on geopolitical issues, such as the Trump administration's proposal to purchase Greenland. The U.S. stance, labeling the resolution as 'ideological,' suggests a resistance to changes that might challenge established visual narratives, even if those narratives are geographically inaccurate. This debate underscores the power of cartography in shaping global understanding and national identity, and how even seemingly objective tools like maps can become subjects of political contention.
What's Next?
While the UN resolution is non-binding, it encourages governments, schools, international organizations, and technology companies to consider using the Equal Earth projection, especially when relative size is important. This could lead to a gradual shift in educational materials and official government maps in many countries. However, popular navigation apps like Google Maps and Apple Maps, which currently use variations of the Mercator projection for its navigational practicality, are unlikely to change their primary map projections in the immediate future. The resolution's backers acknowledge the Mercator projection's usefulness for navigation. The primary impact is expected to be in fostering critical thinking about map projections and their inherent distortions, particularly in educational settings, rather than an immediate overhaul of digital mapping services. The debate may also prompt further discussions on how geographical representations can be more inclusive and accurate.
Beyond the Headlines
This discussion extends beyond mere cartographic accuracy, touching upon ethical and cultural dimensions of representation. The historical dominance of the Mercator projection, developed in the 16th century, reflects a Eurocentric view of the world, visually diminishing the size of continents like Africa and South America. The push for the Equal Earth projection can be seen as an effort to decolonize cartography and promote a more equitable global perspective. The U.S. opposition, framed as a rejection of 'radical ideological projects,' could be interpreted as a defense of existing power structures and a reluctance to acknowledge the subtle biases embedded in widely accepted representations. This incident highlights how seemingly neutral tools like maps are imbued with cultural and political meaning, and how challenging these representations can be a step towards re-evaluating historical narratives and fostering a more balanced understanding of the world.
