Nepal covers just 147,516 km²—less than 0.1% of Earth’s land—but packs in the world’s tallest peak and more biodiversity per square kilometre than almost anywhere else. Squeezed between 28°10′N 84°15′E, it’s a literal crossroads where the icy Himalaya meets the steamy Gangetic floodplain, a narrow bridge between the Tibetan Plateau and the Indian subcontinent.
What’s Nepal’s geographic context?
This tiny wedge is where tectonic plates smash together and monsoon winds dump insane amounts of rain. The altitude swings from 60 m in the Kechana Kalan wetlands all the way up to 8,848 m on Sagarmatha—creating microclimates that feel like entire continents packed into one country. The World Wildlife Fund even lists Nepal among its “Global 200” ecoregions, proving how globally vital its glaciers, cloud-forests, savannas, and alpine meadows really are World Wildlife Fund, Global 200 Ecoregions.
