Conservation and sustainable use of biodiversity have been in the center of policy creation for half a century. The main international biodiversity conventions and processes include the Convention on Biological Diversity (CBD) and its protocols, the Convention on Trade in Endangered Species of Wild Fauna and Flora (CITES), the Convention on Wetlands of International Importance (Ramsar Convention), the World Heritage Convention (WHC), the Convention on Conservation of Migratory Species of Wild Animals (CMS), the International Treaty on Plant Genetic Resources for Food and Agriculture (ITPGRFA), the International Plant Protection Convention (IPPC), the Commission on Genetic Resources for Food and Agriculture (CGRFA), and the International Convention on the Regulation of Whaling (ICRW). The governance of marine biodiversity in areas beyond national jurisdiction (BBNJ) is also discussed, as political focus has shifted to the protection of the oceans and is expected to culminate in the adoption of a new international convention under the United Nations Convention on Law of Seas (UNCLOS). Other conventions and processes with links to biodiversity include the United Nations Convention to Combat Desertification (UNCCD), the United Nations Framework Convention on Climate Change (UNFCCC), and the United Nations Forum on Forests (UNFF).
Despite the multitude of instruments, governments are faced with the fact that biodiversity loss is spiraling and international targets are not being met. The Earth’s sixth mass extinction event has led to various initiatives to fortify the relevance of biodiversity in the UN system and beyond to accelerate action on the ground. In face of an ever more complex international policy landscape on biodiversity, country delegates are seeking to enhance efficiency and reduce fragmentation by enhancing synergies among multilateral environmental agreements and strengthening their science−policy interface. Furthermore, biodiversity has been reflected throughout the 2030 Agenda on Sustainable Development and is gradually gaining more ground in the human rights context. The Global Pact for the Environment, a new international initiative that is aiming to reinforce soft law commitments and increase coherence among environmental treaties, holds the potential to influence and strengthen the way biodiversity conventions function, but extensive discussions are still needed before concrete action is agreed upon.
