Climate Change and Conflict • Climate change issues in HKH region
– Temperature: heat waves, change in growing season – Precipitation: timing, extremes, variability – Glacier changes water supply, GLOFs – Permafrost melt land surface instability, changes to
springs/rivers/lakes and surface water

Climate Change and Conflict • Climate change issues in HKH region (cont.)
– Agricultural yields – Engineering responses: reservoirs, transfer schemes – Develop strains of crops that are most resistant to
climate stress

Climate Change and Conflict • Climate change issues in HKH region (cont.)
– Himalayan hydropower potential • 40% of Nepal population has no access to electricity
– Estimated 80,000 MW of untapped hydropower
– only 700 MW harvested so far
• Bhutan only using 390 MW (1.3%) of 30,000 MW potential • China & India looking to develop Himalayan hydropower

Environmental Security
• What turns a climate change issue into an environmental security issue? – Threat posed by environmental event to individuals,
communities, nations – Esp. when problem crosses international borders
![Page 6: Role of Science in Global Climate Change Policy, Environmental Security, and Sustainability](https://reader033.fdocuments.us/reader033/viewer/2022052506/557bc9add8b42a700d8b4d08/html5/thumbnails/6.jpg)

Environmental Security
• As of late 2011, 33-50% of population in South Asia countries reported to be food insecure – Due in part to flood, drought, environmental
emergencies (World Food Programme 2011)
![Page 7: Role of Science in Global Climate Change Policy, Environmental Security, and Sustainability](https://reader033.fdocuments.us/reader033/viewer/2022052506/557bc9add8b42a700d8b4d08/html5/thumbnails/7.jpg)

Environmental Security
• Number of disasters in South Asia (1900-2010) dominated by floods
![Page 8: Role of Science in Global Climate Change Policy, Environmental Security, and Sustainability](https://reader033.fdocuments.us/reader033/viewer/2022052506/557bc9add8b42a700d8b4d08/html5/thumbnails/8.jpg)

Environmental Security
• People killed/event in last 30 years in South Asia dominated by earthquakes (2005 Kashmir), coastal storms

Environmental Security
• Water treaties effective at reducing conflict, but do not incorporate climate change – Proposed dam & diversions by China on Tsangpo
![Page 10: Role of Science in Global Climate Change Policy, Environmental Security, and Sustainability](https://reader033.fdocuments.us/reader033/viewer/2022052506/557bc9add8b42a700d8b4d08/html5/thumbnails/10.jpg)

Environmental Security
• Indus River Treaty 1960 • Data exchange, but tensions
remain (Wuller Barrage) • Does not include
Afghanistan (Kabul River à Indus)
![Page 11: Role of Science in Global Climate Change Policy, Environmental Security, and Sustainability](https://reader033.fdocuments.us/reader033/viewer/2022052506/557bc9add8b42a700d8b4d08/html5/thumbnails/11.jpg)

Environmental Security
– Nepal has 4 water treaties with India • Kosi River agreements 1954, 1966, 1978 • Gandak Power Project 1959
– Ganges River Treaty (India-Bangladesh) does not include Nepal
![Page 12: Role of Science in Global Climate Change Policy, Environmental Security, and Sustainability](https://reader033.fdocuments.us/reader033/viewer/2022052506/557bc9add8b42a700d8b4d08/html5/thumbnails/12.jpg)

Environmental Security
• Future climate extremes (IPCC 2012) – Heat waves will increase in most regions – Heavy precipitation events will increase – Tropical cyclone wind speeds will increase but
frequency of cyclones may remain unchanged – Coastal damage from sea level rise – Climate extremes water systems, population
mobility & relocation
![Page 13: Role of Science in Global Climate Change Policy, Environmental Security, and Sustainability](https://reader033.fdocuments.us/reader033/viewer/2022052506/557bc9add8b42a700d8b4d08/html5/thumbnails/13.jpg)

Science and Environmental Security
• Very few people in international relations have a deep understanding of science – Excited about ideas…don’t want explanation – Ask “will it work?”
![Page 14: Role of Science in Global Climate Change Policy, Environmental Security, and Sustainability](https://reader033.fdocuments.us/reader033/viewer/2022052506/557bc9add8b42a700d8b4d08/html5/thumbnails/14.jpg)

Science and Environmental Security
• Himalayan climate change response of snow/ice/monsoons human and water security – Impact of these changes remain uncertain, but will
vary… • geographically: east-west, and high-low elevation • season-to-season, year-to-year
– Limited capacity of communities to adjust to changes in…
• quantity/timing of water supply • droughts & floods • glacier lake outburst floods (GLOFs)
![Page 15: Role of Science in Global Climate Change Policy, Environmental Security, and Sustainability](https://reader033.fdocuments.us/reader033/viewer/2022052506/557bc9add8b42a700d8b4d08/html5/thumbnails/15.jpg)

Science and Environmental Security
• Siachen Glacier: “World’s Highest Battleground” – Eastern Karakoram
Range • Just NE of point where Line
of Control between India and Pakistan ends
• Longest glacier in Karakoram • Elevations 18,875 ft. to
11,875 ft.
![Page 16: Role of Science in Global Climate Change Policy, Environmental Security, and Sustainability](https://reader033.fdocuments.us/reader033/viewer/2022052506/557bc9add8b42a700d8b4d08/html5/thumbnails/16.jpg)

Science and Environmental Security • Siachen Glacier
– India & Pakistan claim soverignty over Siachen region
• India has held control since 1984 • More soldiers have died from exposure than from combat • Dumping of non-biodegradable waste, arms & ammunition à
Nubra River à Shyok River à enters Indus River near Skardu (used for drinking & irrigation
• Glacier shrinking rapidly

Science and Environmental Security
• 7 April 2012: 138 Pakistani soldiers and civilians killed by ice-rock avalanche

• Proposal to DoS by Sandia Labs to designate the area a World Peace Park: “Siachen Science Center” “

• Address issues of climate change policy and environmental security with “best available science” or “sound science” – Seek decisions that are objective and unbiased – Need to recognize that science is not static
• Science is a process, not an outcome or product • Ongoing consultation is desirable • Best available science is often inconclusive or incomplete

• Assess data accuracy – What kinds of data and amounts of data must be
collected to assess… • climate change? • mitigation activities?
– How long will it take to have confidence that an action is or is not working?
– Are adequate experimental designs being used to answer specific questions, or are data being collected based on other constraints?

• What is the threshold on certainty before agency should act? – Not the same as burden of proof within scientific
community (e.g., 95%) – Agencies should act when they are “not likely” to
cause adverse effects

• Science is not the only basis for policy formation!
• Other criteria – Economics > Politics > Science – Common sense – Trial and error (incrementalism) – Professional rubrics, accepted practices – Direct experience, beliefs, tradition – Voting – Lawsuits

Science and Environmental Security
• Ability to build resilience in HKH communities is limited by – Communities most affected are not engaged
• Involve the stakeholders – Example: High Mountain Glacial Watershed Program

“One of the marks of the value of a scholarly discipline is the extent to which it has something to say about matters of social significance”

Communicating Science
• Climate change skeptics • Scientific skepticism is healthy, in general • “Climate change denial” is different
• Vigorously criticize any evidence for climate change, esp. if it involves human
• Embrace any arument, op-ed, blog, article that refutes climate change
• Exercise: points and counterpoints www.skepticalscience.comm/argument.php
