International Day of the Tropics Hero

Alexander von Humboldt

Alexander von Humboldt (1769-1859) was a Prussian polymath, geographer, naturalist, explorer, and proponent of romantic natural philosophy. His extensive expeditions through Latin America from 1799 to 1804 were pioneering in their scientific rigor and holistic view of nature.

History of International Day of the Tropics

On June 14, 2016, the United Nations General Assembly passed a resolution designating June 29 as International Day of the Tropics. The United Nations chose June 29 to honor the anniversary of the first ‘State of the Tropics Report.’ Myanmar’s Nobel Laureate, Aung San Suu Kyi, launched the report in 2014.

The tropics are a geographic area of the Earth that roughly corresponds to the area between the tropics of Cancer and Capricorn. Although topography and other factors influence the climatic variation, tropical areas are typically warm with little seasonal variation in day-to-day temperature.

The presence of rain in the moist inner zone near the equator is an important feature of the Tropics and the seasonal patterns of rainfall rise with distance from the equator. Climate change, deforestation, logging, urbanization, and demographic changes are all threats to the tropical region.

On June 29, 2014, the first State of the Tropics Report was believed to be the result of collaborative efforts among twelve leading tropical research facilities. The report provides a unique perspective on this rapidly growing region. To commemorate the report’s launch anniversary, the United Nations General Assembly passed resolution A/RES/70/267 in 2016, declaring June 29 as International Day of the Tropics.

The International Day of the Tropics is intended to raise awareness of the particular problems that tropical areas face, the far-reaching impacts of issues affecting the world’s tropical zone, and the need, at all levels, to raise awareness and highlight the critical role that tropical countries will play in achieving sustainable development.

While the tropics encompass some of the best vacation destinations, these areas also play critical roles in achieving sustainable development. The tropics, however, face several challenges, including climate change, urbanization, demographic shifts, and deforestation.
