The International Programme on Landslides (IPL) is a Programme of the International Consortium on Landslides (ICL) for Landslide Disaster Risk Reduction. It was originally launched in November 2002. The new IPL was defined and established by the 2006 Tokyo Action Plan “Strengthening Research and Learning on Landslides and Related Earth System Disasters for Global Risk Preparedness.” In order to promote the IPL and the 2006 Tokyo Action Plan, ICL exchanged a Memorandum of Understanding (MoU) with each of the seven United Nations and International Stakeholders: UNESCO, WMO, FAO, UNDRR, UNU, ISC, WFEO. The logo of IPL includes the ICL and seven global stakeholders.

The IPL is managed by the Global Promotion Committee of the International Programme on Landslides and the Kyoto Landslide Commitment 2020 (GPC/IPL-KLC). The IPL activities include IPL projects proposed by ICL members and ICL Network coordinators being approved by GPC/IPL-KLC every year, and the World Centers of Excellence on Landslide Risk Reduction (WCOEs) are proposed and approved by GPC/IPL-KLC every 3 years. This session is devoted to activity reports of ongoing IPL projects, ICL Networks, ongoing WCOEs (2023-2026), and new proposals of IPL projects and WCOE (2026-2029).

Understanding and Reducing Landslide Disaster Risks as Cascading and Multi-Geohazards are the key and important perspective to promote landslide risk reduction on a global scale. This session addresses cascading multi-hazard risks involving landslides, tsunamis and impacts on infrastructures. The landslides that trigger tsunamis represent coastal and submarine landslides, river landslides, reservoir landslides, lake landslides, as well as fjord landslides. The origins range widely from earthquakes to volcanoes, rainfalls, rising water levels, and others. The combined effects of triggering factors, including rainfall, earthquakes, and volcanic eruptions, can lead to greater impacts through disastrous landslides such as lahars, debris flows, rock falls, and megaslides across the earth surface. Critical infrastructures in mountains, coastal and offshore areas are at risks from cascading multi-hazards that include landslides, tsunamis, earthquakes and volcanic eruptions. Understanding and reducing such multi-hazard risks will require developing a better understanding of the multiple mechanisms and multi-phased physics of the relevant cascading multi-hazard phenomena pertaining to landslides including landslide tsunami hazard. An international collaborative network and platform would be important for such a multi-hazard risk reduction. In this framework, this session promotes understanding and reducing landslide disaster risks as cascading and multi-geohazards at both the regional and global scales.

By definition, landslide related studies are often subject to many factors that can negatively influence the impartiality, transparency, inclusivity, and standards of conduct of individuals. Today more than ever before, landslide researchers need to critically evaluate all stages of their work from site selection, project goals, participation, output dissemination, quality control, data sharing, authorship, accountability, and other issues based on a foundation of ethical values and practice. This session provides an opportunity to present and discuss a suite of topics, case studies and strategies that are germane to ethical landslide research. We encourage practitioners to submit contributions related to landslide ethics as examples include conflicts of interest, gender/ageism biases, questionable peer reviewing, breaches of standards, work safety avoidance, developed country favoritism, information hoarding, rumor impacts, social media abuse, limiting education, and respecting privacy are but a few examples of the many ethical issues that can impede the positive growth and progress in landslide studies.

KLC2020 also defines in its Action 5 «Promote open communication with local governments and society through integrated research, capacity building, knowledge transfer, awareness-raising, training, and educational activities, to enable societies and local communities to develop effective policies and strategies for reducing landslide disaster risk, to strengthen their capacities for preventing hazards from developing into major disasters, and to enhance the effectiveness and efficiency of relief programs.”

This Session therefore also aims at knowledge exchange among diverse stakeholders (from academic institutions, research institutions, international organizations, non-governmental organizations, engineers, policy makers, local communities, …), including ICL community how Open Science and Open Educational Resources can and should be developed in the field of capacity development and education for landslide risk reduction. Reports and expertise papers, case studies and best practices papers are welcome to shed light on how these new educational and research ways have already been or may be successfully applied worldwide in future to meet Sendai Framework 2015-2030 for Disaster Risk Reduction and Agenda 2030 Sustainable Development Goals in the field of Landslide Disaster Risk Reduction.

Stability analysis of slopes plays a significant role in understanding the behavior of slopes so that appropriate protection measures can be designed. With the advancement in analysis methods, computing technology, and speed of computer processors, we have seen a significant advancement in slope stability and deformation analysis methods. In particular, several 3-D and 4-D analyses methods have been successfully implemented in the recent decades. Even for 2-D analysis methods, approach to input soil/ground properties in reasonable ways have made our slope stability analyses more accurate and closer to the field situation. In this session, we invite abstracts from practitioners/researchers who have developed or practiced different slope stability analysis methods in the evaluation of landslides or mass movements, or worked in case studies of landslide hazard mitigation where slope stability analyses were performed to design and monitor the protection measures.
