The ANNEX to the 2017 Ljubljana Declaration on Landslide Risk Reduction described in the “Preface” section of this issue is the list of participants (by organizations) in the Fourth World Landslide Forum. In this article, emphasis is put on this list of organizations as they are expected to be the key components for the Fifth World Landslide Forum 2020 in Kyoto, Japan. The participants in the Fourth World Landslide Forum 2017 adopted the 2017 Ljubljana Declaration on Landslide Risk Reduction. They further endorsed the concept of the Kyoto 2020 Commitment for Global Promotion of Understanding and Reducing Landslide Disaster Risk. The commitment aims to establish a long-term, wider, and stronger network after WLF5 2020 among three membership categories, namely, the International Consortium on Landslides (ICL) full members/supporters/associates, ICL-supporting organizations (UN and international global organizations) and ICL-supporting governments, and ISDR-ICL Sendai Partnerships 2015–2025. This article introduces three categories of ICL memberships and calls for participation.
