Disaster Prevention Monitoring through Wireless Networking and Filed Server Prashant Manandhar Nepal Research & Education Network (NREN). 26 th APAN Meeting, August 2008 Queenstown, New Zealand
Glacial Lake out burst and extreme weather Monitoring, Partner with NARC, APAN JP, KEIO University Japan Imja Glacial Lake Base of Island Peak Formed by melting of glaciers Large Lake, narrow outlet Stones and pebbles Water level is rising Global Warming Risk of Glacial Lake Out-Burst (GLOB) Several villages downstream might be affected directly if the lake bursts Freezing Wireless – SANOG XI, Dhaka, Bangladesh
Impact of Climate Change in the Himalayas Rate of increase of warming by 0.15 °C to 0.6 °C per decade Rate of glaciers shrinking is higher in recent decades The numbers of Glacial lakes are increasing in the high Himalayas Glacial lakes outburst floods (GLOFs) Nepal Context 8 out of 10 highest Mountains in the world Total Glaciers - 3252 covering 5223 sq. km in Nepal 2323 glacial lakes in Nepa ( Source: ICIMOD and UNEP)
Potentially dangerous glacial lakes Source: Hiromichi FUKUI, Faculty of Policy Management, Global Security Research Center, Keio University
Glaciers and glacial lakes in Nepal Glacial lakes - 2323 Koshi Basin Mahakali Basin Karnali Basin Gandaki Basin
THE HIGHEST RISK; GLACIAL LAKE OUTBRUST FLOOD The highest risk from climate change is the increasing risk of Glacial Lake Outburst Flood Impacts UPON mountain eco-system Displaces downstream villages Further south, huge damage to corps and other livelihoods Big Damage due to Dig Tso burst in 1985 Preventive work done in only in Tso Rolpa Current Research Work between NREN, ICIMOD, DNPW, Keio University, NARC/NARO Japan and APAN-JP on Imja- Tso

Glacial Lake out burst and extreme weather Monitoring, Partner with NARC, APAN JP, KEIO University Japan Imja Glacial Lake, 5100 ~ 5200m Base of Island Peak Formed by melting of glaciers Large Lake, narrow outlet Stones and pebbles Water level is rising Global Warming Risk of Glacial Lake Out-Burst (GLOB) Several villages downstream might be affected directly if the lake bursts Freezing Wireless – SANOG XI, Dhaka, Bangladesh
Objectives To demonstrate the real time monitoring of Imja glacial lake as a pilot study To provide early warning and save the lives of people living downstream and properties, infrastructure and environment To build local area Wireless network (wifi) between the villages and connect with VSAT terminal to provide Internet connectivity and access for the local community

Current NREN Activity in Mt. Everest Region Our efforts are to connect medical across regions to collaborate Help ongoing research in high altitude sickness and associated areas Setup training mechanism to help health workers in remote areas to contact / converse over networking mediums to experts in hospitals. Other software than can assist in these.
Lessons Learned ICT technologies can help in monitoring and documenting climate changes. Will also help in taking preventive measures. ICT can also increase the awareness in local communities about potential hazards A public private partnership between local communities, government, service providers and scientific researchers can only get the work done.
Technology Lessons Learned Wireless Network can be made to work in remotest areas Low power self sufficient devices embedded with appropriate sensors are needed to avoid big impact on fragile ecosystem Power storing technology still needs more work for remote and cold areas.
Next Steps Enhanced observation, monitoring Promote exchange of data and information Enhance cooperative studies among other area Promote capacity building Consider systematic way for mitigation and adaptation
Our Next Plan for Climate Changes Deploy more wireless enabled field stations Weather stations, sensor network, field servers Build a network from Everest region to Dhaulagiri /Annapurna region to monitor changes happening between the six 8000m+ and several 7000m+ mountains in the region.
