About International Day of the Tropics
The International Day of the Tropics is marked every year on June 29 to draw attention to the remarkable region that straddles the equator and to the challenges its people face. The tropics cover roughly forty percent of the planet's surface, hold most of its rainforests, and provide a large share of its biodiversity, yet they also host the majority of the world's poorest populations.
Designated by the United Nations General Assembly, the day highlights findings from the State of the Tropics report, a project led by a consortium of research institutions. Those reports track trends in health, education, food security, and climate across more than one hundred tropical countries and territories.
The observance is a call to pay attention to a region that is growing fast in population and economic weight while coping with deforestation, rising temperatures, and rapid urbanization. It asks the rest of the world to recognize both what the tropics give the planet and what they stand to lose.

History of International Day of the Tropics
The date commemorates the launch of the inaugural State of the Tropics report, released on June 29, 2014, by a coalition of twelve leading research institutions coordinated through James Cook University in Australia. The report offered the first comprehensive assessment of the tropical region as a whole, covering environmental, social, and economic indicators side by side. Impressed by its scope, the United Nations General Assembly adopted a resolution in 2016 designating June 29 as the International Day of the Tropics. Each year's observance since has spotlighted a theme, from biodiversity and forests to climate change and sustainable development, and has encouraged policymakers, universities, and community groups to share research and practical solutions.
