2 BACKGROUND The World Landslide Forum (WLF) is a triennial world conference of scientists, engineers, practitioners and policy makers, aiming at international exchange of knowledge, experiences and latest trends in science and engineering development and with focus on landslide risk governance. The WLF1 was organized in 2008 in Tokyo, Japan, followed in 2011 by the WLF2 in Rome, Italy, and in 2014 by the WLF3 in Beijing, China. The Fourth Forum is a contribution to the implementation of the Sendai Framework for Disaster Risk Reduction 2015-2030 which was adopted by the United Nations Member States on 18 March 2015 at the Third UN World Conference on Disaster Risk Reduction (3rd WCDRR) in Sendai City, Miyagi Prefecture, Japan. It is an activity of the UN International Strategy for Disaster Reduction (ISDR).

OBJECTIVES The WLF4 has an objective to be a worldwide event for discussing how landslide research and landslide risk reduction can contribute to advancing the culture of living with natural hazards. Risk governance in the field of landslide disaster risk reduction and management means to establish an effective bottom-up system incorporating many relevant stakeholders into a risk dialogue, and enhancing risk communication with the aim to build a sustainable system of prevention and disaster relief in the field of landslide disaster risk reduction. The WLF4 will be the first opportunity to evaluate the progress in the implementation of the ISDR-ICL Sendai Partnerships 2015-2025 for Global Promotion of Understanding and Reducing Landslide Disaster Risk, officially accepted in 2015 at the 3rd United Nations World Conference on Disaster Risk Reduction in Sendai, Japan.

Strengthening Intergovernmental Network and the International Programme on Landslides (IPL) for “ ISDR-ICL SENDAI PARTNERSHIPS 2015-2025 for global promotion of understanding and reducing landslide disaster risk”

Objectives The International Programme on Landslides (IPL) is a programme of the International Consortium on Landslides (ICL). ICL proposed the IPL in a thematic session of the Second World Conference on Disaster Reduction (WCDR) in Kobe, 2005. The activities of IPL were defined in the 2006 Tokyo Action Plan “Strengthening research and learning on landslides and related earth system disasters for global risk preparedness” at the Round Table Discussion held in Tokyo, 2006. IPL was supported by 7 global stakeholders of UNESCO, WMO, FAO, UNISDR, UNU, ICSU and WFEO, and ICL exchanged MoU to promote the Tokyo Acton Plan with each of them in 2006. The activities of IPL include the triennial organization of the World Landslide Forum, the implementation of various IPL Projects, identification of World Centres of Excellence on Landslide Risk Reduction (WCoE), and the publication of the ICL bimonthly journal Landslides. Based on this background, ICL proposed the ISDR-ICL Sendai Partnerships 2015-2025 for global promotion of understanding and reducing landslide disaster risk at the 3rd WCDRR in Sendai, 2015 which was accepted and signed by 17 global and national stakeholders including the governments of Croatia, Italy and Japan. This high-level panel discussion aims to strengthen networking with governments in landslide-prone countries and governments supporting landslide disaster risk reduction efforts in developing countries. The close cooperation within governments, United Nation Organizations and International NGOs is necessary and effective to implement the ISDR-ICL Sendai Partnerships 2015-2025 and the International Programme on Landslides (IPL) as its infrastructure.

9 Session 1. 3 – Landslides and Society

Convener: Irasema Alcántara-Ayala (Mexico), Sálvano Briceno (Venezuela/France), Paola Salvati (Italy). E-mail < [email protected]> This session focuses on the interactions between landslides and societies, as they have not been fully addressed by researchers and policy makers. Human induced modifications to landscapes, particularly land-use changes, affect the stability of slopes. What is more, quite commonly lacking of territorial planning and management in both, rural and urban areas, leads to the establishment of human settlements in areas susceptible to landslides. Owing to the present and future expansion of population, derived from rapidly expanding urbanization processes and the pressure for land and natural resources use, coupled with high levels of vulnerability and exposure, landslide disaster risk construction and landslide disasters will continue to increase around the world. In spite of great efforts made by the scientific community to understand landslide hazards, evaluations regarding social vulnerability and exposure to landslides remain as urgent pending tasks. Papers and case studies on socio-economic vulnerability, exposure, risk perception and communication, capacity building, education, institutional and governance development at local, sub- national, national, regional and international scales are invited to contribute to the discussion. 1. Legislation & Risk Communication for landslide risk reduction. 2. International, national and regional efforts of Capacity Building & Education. 3. Case studies of landslide risk reduction efforts integrating local and regional communities.

Theme 2 – Advances in Landslide Science (Coordinator: Binod Tiwari, USA) E-mail There has been a significant progress in the field of landslide science in recent years.
