International Day of the Tropics:

29 June 2018

International Day of the Tropics was celebrated on the 29th of June. This is a region that faces a number of challenges such as deforestation, logging, urbanization and demographic changes and is particularly vulnerable to droughts, floods and storms as climate change accelerates.

Did you know that:

- The Tropics account for 40% of the world’s total surface area and are host to approximately 80% of the world’s biodiversity - The Tropics host nearly 95% of the world’s mangrove forests by area and 99% of mangrove species - The Tropics have just over half of the world’s renewable water resources and yet almost half of their population is considered vulnerable to water stress.
At DHI GRAS, we have several projects with pilot sites located in the Tropics, where we help to develop and demonstrate how earth observation can benefit sustainable development in a number of different ways.
