The Convention on Biological Diversity (CBD) is an international agreement established by the United Nations. Its aim is to preserve biological diversity around the world. Belgium became a CBD member during the Earth Summit in Rio de Janeiro, in 1992.

The CBD has three main objectives: to conserve biodiversity, to enhance its sustainable use and to ensure an equitable sharing of benefits linked to the exploitation of genetic resources.

The Convention puts much emphasis on the exchange of information and the cooperation between countries. To help these processes, the CBD has set up an international network of partners called the Clearing-House Mechanism (CHM). This website contributes to the CHM network by illustrating what Belgium is doing in the framework of the CBD.
