Organizer: IPL Global Promotion Committee
Establishment of International Consortium on Landslides
January 21, 2002
Leading landslide researchers and UNESCO, WMO, UNISDR, MOFA,
MEXT joined the foundation meeting of ICL during the UNESCO-
Kyoto University Joint Symposium.
To create an International Programme on Landslides
(The first international science programme proposed from Japan)
To create an international platform putting Science into Practice
Establishment of the International
Programme on Landslides (IPL)
1. The initial IPL was established at UNESCO in November 2002.
2. ICL, UNESCO, UNISDR etc organized the Thematic Session on IFI
and IPL during the World Conference on Disaster Reduction
(WCDR) in January 2005 in Kobe, and adopted the Letter of Intent
“to promote research and learning for landslide risk reduction”.
3. The Round Table Discussion “Strengthening Research and Learning
on Earth System Risk Analysis “ -Toward a dynamic global network
of International Programme on Landslides (IPL)- was organized in
January 2006 at UNU by ICL, UNESCO, UNISDR, ICSU etc with
supports from MOFA, MEXT, etc. and adopted the 2006 Tokyo
Action Plan to establish a new IPL as a global scientific programme
4. The International Programme on Landslides (IPL) was established by
the Tokyo Action Plan as a global scientific programme .
UNESCO, WMO, FAO, UNISDR, UNU, ICSU, WFEO exchanged
MoU with ICL to implement IPL within the Year 2006.

Disaster Risk Reduction (ISDR). IPL is managed by the IPL Global
Promotion Committee

The First World Landslide Forum
18-21 November 2008, at UNU, Tokyo
Organizers: ICL, UNESCO, WMO, FAO, UNISDR, UNU, ICSU, WFEO, etc
Cosponsors: CAO, MOFA, MEXT, MAFF, MLIT, JMA, SCJ, JICA, etc
The Forum was financially supported by MOFA (20 million JPY)
through UNISDR and the Grant-in-Aid of MEXT(10 million JPY) , etc
430 persons attended from 48 countries with those funds.
It was the largest meeting on landslides in the past.

Risk Assessment Technology of Earthquake
Induced On-land and Submarine Megaslides
Landslides cause big disaster in many countries.
Landslides are triggered by rains, earthquakes, and
also often the combined effects of both triggers.
Catastrophic megaslides often occur near the Plate
borders on-land and also under the sea.
Submarine landslides may trigger or enhance
Tsunami wave.
Risk Assessment Technology and Preparedness for
earthquake induced on-land and submarine
landslides are needed to prepare landslide disasters.

Global Network of IPL may be promoted through Journal, IPL Projects, WCOE,
WLF and New Initiatives of:
1.Establishment of the Regional Consortium on Landslides, such as Adriatic-Balkan,
ASEAN, Latin-American, possibly African and South-Asian, Arabian, etc. proposed
in December 2010.
2.Development of Landslide School Network with ICL and Non-ICL organizations
approved in November 2010.
3.World Reports on Landslides (Database) agreed in January 2011 in Kyoto
Secretarial meeting and read to upload in IPL WEB.10th Anniversary of ICL
ICL was established in Kyoto to create IPL on 21
January 2002 with participants from UNESCO,
UNISDR, WMO with supports from the Government of
Japan.
ICL and IPL have developed through this decade.
The 10th Anniversary of ICL, Symposia on IPL projects,
the programme planning meeting of WLF-3 in Beijing,
2014, and the Round Table Discussion to make a strategy
for the next decade will be organized in Kyoto on 18-20
January 2012.
Let’s meet and further discuss again in Kyoto at the 10th
anniversary of ICLWishing Further Development of
Global Network of IPL
