International Day of the Tropics

International Day of the Tropics History

The International Day of the Tropics is an annual observance that aims to recognize and raise awareness of the significant challenges and opportunities faced by countries located within the tropics. The day seeks to promote the diverse nature of the tropics, as well as challenge the negative stereotypes often related to the region.

The day was first declared by the United Nations General Assembly in 2016, with the aim of promoting sustainable development within the tropics. The tropics cover approximately 40% of the Earth's surface and are home to over 80% of the world's biodiversity. The region is also a key contributor to global economic growth, with industries such as tourism, agriculture and fishing all relying on the tropical climate.

The United Kingdom recognizes the importance of the tropics, and celebrates the International Day of the Tropics alongside other nations around the world. The day serves as an opportunity to highlight the unique challenges faced by countries in the tropics, such as climate change, poverty and disease. It also promotes the significant contributions that can be made to global development through sustainable development practices in tropical regions. The International Day of the Tropics is observed annually on June 29th.
