Megadiverse countries are a group of nations that contain more than 70% of the planet's biodiversity. They were identified in 1998 by the Center for Environmental Conservation Monitoring (CECM) to promote awareness of biodiversity conservation among the nations of the world. According to the Monitoring Center, there are 17 of these nations, which are mainly in the tropical or subtropical region and contain the highest biodiversity index. These countries have effectively joined to negotiate the development of the Nagoya Protocol, which deals with access to genetic resources and fair and equitable sharing of the benefits derived from their use during the Convention on Biological Diversity that was adopted in Japan in 2010.
Megadiverse countries are a group of countries that are home to most of the Earth's species of both plants and animals and are therefore considered to be highly biodiverse. They account for 60-70% of the world's biodiversity.
In February 2002, Ministers in charge of the Environment and delegates from Bolivia, Brazil, China, Colombia, Costa Rica, Democratic Republic of Congo, Ecuador, India, Indonesia, Kenya, Madagascar, Malaysia, Mexico, Peru, Philippines, South Africa, Venezuela met in Cancun, Mexico. During this meeting, the countries agreed to establish a Group of Like-Minded Megadiverse Countries as a mechanism for consultation and cooperation so that, their interests and priorities related to the preservation and sustainable use of biological diversity can be promoted.
They also stated during the meeting that they would ask countries that had not yet become parties to the Convention, the Cartagena Protocol based on biosafety and the Kyoto Protocol that sets out guidelines on climate change to become parties to these agreements.
The main characteristics of the countries that have been catalogued as Megadiverse countries are the following:
The American continent has the largest number of countries considered as megadiverse. It has seven countries that are the following:
This continent is home to five countries considered Megadiverse, and these are:
Here we can locate the following countries:
This is the last continent in which there are two Megadiverse countries:
Let us remember that biological diversity refers to all the living beings that inhabit the Earth, and the term includes the variety of ecosystems and the genetic maps of the different forms of life. The number of plant and animal species and their relationships and biological forms together constitute the biodiversity of a country or region. So we can say that the Megadiverse countries receive this name because they have unique characteristics that allow them to house a large number of different species.
Many of these countries are located in the tropics, where the conditions for biodiversity are even greater, their landscapes offer a great diversity of environments, soils and climates, and the separation of islands and continents that once suffered, has allowed the development of endemic flora and fauna, which are unique in those places, their large size helps to house more species, their evolution has developed through the contact of several regions where species with different origins have been mixed, and plant and animal domestication by peoples has given rise to great natural wealth in these areas.
