Why International Day of the Tropics Matters

The tropics span from the Tropic of Cancer in the north to the Tropic of Capricorn in the south, covering 36% of the world's total surface area.

This increasingly important region is known for its warm day-to-day temperature, supporting 80% of the world's biodiversity and 40% of the world's population. Despite its rich resources, the Tropics face widespread poverty, limited access to food and water, and health issues.

Since the tropics also affect global weather patterns and climate, the region is disproportionately affected by climate change, as evidenced by rising temperatures, heightened sea levels, and extreme weather events.

Deforestation also leads to habitat destruction, loss of biodiversity, and climate change acceleration. Moreover, indigenous communities often bear the brunt of these challenges.

This global observance calls for safeguarding these crucial regions, highlighting the unique challenges of tropical countries, and respecting the rights and traditions of indigenous peoples.

Other Data and Statistics

About 85% of the world's poorest citizens reside in the tropics.

The tropics contain about 54% of the renewable water resources worldwide.

One-third of the tropical rainforest is either gone, degraded, or intact.
