Three environmental conventions, two of which were adopted at the 1992 “Earth Summit” in Rio de Janeiro: the United Nations Framework Convention on Climate Change (UNFCCC), and the Convention on Biodiversity (CBD), while the third, the United Nations Convention to Combat Desertification (UNCCD), was adopted in 1994. The issues addressed by the three treaties are related — in particular, climate change can have adverse effects on desertification and biodiversity — and through a Joint Liaison Group, the secretariats of the three conventions take steps to coordinate activities to achieve common progress.
