The APN believes that working in partnership with other organisations involved in global change research is essential to maximise the resources available and to deliver the best possible results. In particular, the APN cooperates closely with the global change SysTem for Analysis, Research, and Training (START), the International Geosphere-Biosphere Programme (IGBP), the International Human Dimensions Programme on Global Environmental Change (IHDP), the World Climate Research Programme (WCRP), and the international programme of biodiversity science DIVERSITAS.
