The Fifth World Landslide Forum in Kyoto, Japan, November 2021

The Fifth World Landslide Forum (WLF5) was postponed from 2–6 November 2020 to 2–6 November 2021 due to COVID-19. However, the planned full color books Understanding and Reducing Landslide Disaster Risk have been completed to collect and edit. The six full color books will be published early January 2021, and the electronic proceedings will be published by the end of 2020. The planned Kyoto Landslide Commitment 2020 was launched on 5 November 2020 (Sassa, 2021).

The WLF5 organizing committee has decided to organize the Forum 5 as a hybrid conference for participation in Kyoto and remote online-virtual participation. The updated information of WLF5 after the last article (Sassa, 2020) is announced in this article.

Aim

World Landslide Forums have been organized every 3 years after the first forum in Tokyo, Japan, in 2008. It is a common platform for scientists, engineers, practitioners, and policy-makers who are involved in landslide disaster risk reduction to present their latest progress. The Sendai Landslide Partnerships 2015–2025 for Global Promotion of Understanding and Reducing Landslide Disaster Risk was adopted on 16 March 2015 as a voluntary commitment to the United Nations World Conference on Disaster Risk Reduction, held in Sendai, Japan, in 2015. It is a supporting tool for the implementation of the Sendai Framework for Disaster Risk Reduction 2015–2030. In order to implement further the Sendai Landslide Partnerships 2015–2025 and pursue and enhance efforts to 2030 and beyond, the Kyoto 2020 Commitment for global promotion of understanding and reducing landslide disaster risk (KLC2020)—A Commitment to the Sendai Landslide Partnerships 2015–2025, the Sendai Framework for Disaster Risk Reduction 2015–2030, the 2030 Agenda Sustainable Development Goals, the New Urban Agenda, and the Paris Agreement—was launched by all signatory organizations at the online launching session of KLC2020 on 5 November 2020. The Fifth World Landslide Forum will be the opportunity to achieve a mid-term review of the Sendai Landslide Partnerships 2015–2025, and a 1-year review and planning of the further development strategy of KLC2020.
