There are 17 megadiverse countries on our planet.
But what does this mean: 'megadiverse'? Which countries are these and where are they located? And what makes a country 'megadiverse'?
Megadiverse countries are all the countries on our planet that house a large number of endemic species. 'Endemic' means species that only exist in this country.
When is a country called 'megadiverse'?
There are two basic conditions:
Mega-diverse countries thus have a high biodiversity within their borders. This means there are many more animal and plant species living in these countries than in other parts of the world.
The 17 countries cover about 10% of the Earth's surface but are home to more than 70% of all species.
These 17 mega-diverse countries (of all 195 countries around the world) house more than
There are countries with high biodiversity on all continents, though the natural environment in Europe and that on Antarctica is not as biodiverse as certain regions in North and South America, Africa, Australia and Asia.
According to Conservation International 1988, these are the 17 megadiverse countries:
In South America:
In North America:
'Biodiversity' means that there are many different species living on our planet. Some countries have more variety in species than others.
'Megadiversity' means there is extreme high biodiversity. All the countries that are called 'megadiverse' have a very high biodiversity, that means many different species of animals and plants exist in the country.
Most of the countries that are especially rich in flora (plants) and fauna (wildlife) are located in the tropical regions.
Which country is known for having the highest biodiversity of all countries?
Brazil is the top megadiverse country and has the highest biodiversity. It is understood that up to 20% per cent of biological diversity in the world is found within Brazil. The country houses
The concept was first published by Russell Mittermeier in 1988.
The aim of this concept was to raise awareness especially in those countries about threatened species to help protect the natural biodiversity of the country.
The main challenge of megadiverse countries are deforestation, overfishing and climate change. The highly biodiverse countries are most threatened and the change in their ecosystems will affect all of us on our planet.
For example, the Philippines which have the fifth highest biodiversity loose a high amount of forest every year. This affect all of us on this planet. Any change to the land will affect the rate of biodiversity.
The Philippines are known for their many species of bananas, rice or coconut, however, with changing agricultural patterns this will affect the diversity of the species as well.
