During the COP 14 (Conference of the Parties of the Convention on Biological Diversity, CBD), the 4th Science Forum is organised by IUBS, the European Commission with EKLIPSE, IAI and the CBD secretariat. The objective of this Science-Policy dialogue would be to bring together and engage scientists and policy makers in a transparent dialogue, to recommend how to bring the post-2020 process forward. It can open new pathways to accelerate implementation of nature-based solutions for nature, people and the economy across different sectors, and on engaging wider parts of the society. The Science Forum took place in Sharm el-Sheikh, Arab Republic of Egypt, 23-24 November 2018.
