International Day of the Tropics: Region to host two-thirds of world’s children by 2050

By 2050, the tropical region will host most of the world’s people and two-thirds of its children.

Mangroves

The tropical region hosts nearly 95% of the world’s mangrove forests by area and 99% of mangrove species

The UN, which made the disclosure on Friday, June 29, 2018 in commemoration of the International Day of the Tropics, pointed out that the proportion of the urban population living in slum conditions is higher in the Tropics than in the rest of the world.

“Consistent with the higher levels of poverty, more people experience undernourishment in the Tropics than in the rest of the world,” the global body stated.

While it hosts nearly 95% of the world’s mangrove forests by area and 99% of mangrove species, the area of mangrove forest has however decreased in all tropical regions since 1980, stated the UN.

“The Tropics have just over half of the world’s renewable water resources (54%), yet almost half their population is considered vulnerable to water stress.

“Biodiversity is greater in the Tropics across most taxonomic groups, with an equivalently higher proportion of threatened species. For those plants and animals for which there are adequate data, loss of biodiversity is greater in the Tropics than in the rest of the world.”

The Tropics are a region of the Earth, roughly defined as the area between the tropic of Cancer and the tropic of Capricorn. Although topography and other factors contribute to climatic variation, tropical locations are typically warm and experience little seasonal change in day-to-day temperature. An important feature of the Tropics is the prevalence of rain in the moist inner regions near the equator, and that the seasonality of rainfall increases with the distance from the equator.

The Tropics account for 40 per cent of the world’s total surface area and are host to approximately 80 per cent of the world’s biodiversity and much of its language and cultural diversity. The tropical region faces a number of challenges such as climate change, deforestation, logging, urbanisation and demographic changes.

Observed on June 29, the International Day of the Tropics celebrates the extraordinary diversity of the tropics while highlighting unique challenges and opportunities nations of the Tropics face. It provides an opportunity to take stock of progress across the tropics, to share tropical stories and expertise and to acknowledge the diversity and potential of the region.
