In 1992 state and government leaders agreed on a strategy for sustainable development at the United Nations Conference on Environment and Development, also known as 'The Earth Summit', in Rio de Janeiro, Brazil. Sustainable development is a way to meet the needs of people all over the world and ensuring that planet earth remains healthy and viable for future generations. One of the most important agreements reached during the Earth Summit was the Convention on Biological Diversity.
The Convention on Biological Diversity came into force on December 29, 1993, and each anniversary of this date was designated the International Day for Biological Diversity. From 2001 onwards the date of this celebration was moved to May 22 due to the number of holidays that fell in late December. On this date in 1992, the text of the Convention on Biological Diversity was adopted at a United Nations at a conference in Nairobi, Kenya.
Each year, the International Day for Biodiversity focuses on a particular theme. Recently, the themes have been: Biodiversity and Poverty Alleviation (2003); Biodiversity: Food, Water and Health for All (2004); Biodiversity: Life Insurance for our Changing World (2005); Protect Biodiversity in Drylands (2006); and Biodiversity and Climate Change (2007); and Biodiversity and Agriculture (2008).
