3Glacial melt---
- The temperature increase in the Himalayan region
has been greater than the global average of 0.74
C over the last 100 years (IPCC 2007). - The higher the altitude the more rapid the
warming. - This ongoing rapid warming has a profound effect
on the Himalayan environment. - Retreat of glacier tongues has led to the
formation of glacial lakes. - The resulting glacial lake outburst flood (GLOF)
can cause damage to life, property, forests,
farms and infrastructure.
4Glaciers in the Hindu Kush-Himalayas
5The melting glaciers in the Himalayas
- Glaciers in the Himalayas are receding faster
than in any other parts of the world. - In Northwest China, 27 of the glacier area will
decline by 2050 (equivalent to an ice volume of
16,184 km3), as will 10 to 15 of the frozen soil
area. - IPCC made a forecast that if current trends
continue, 80 of Himalayan glaciers will be gone
in 30 years recent estimates suggest this loss
in 50 years. - The current trends of glacial melt suggest that
the Ganges, Indus, Brahmaputra and other rivers
across the northern Indian plain could likely
become seasonal rivers in the near future. - Between 20 and 40 reduction of runoff per capita
is likely by the end of 21st century in the NW
provinces of China.

than elsewhere

9Glacial melting in Tibetan Plateau
- Glacier recession on the Tibetan Plateau has
quickened, triggering a series of environmental
calamities. - Winters are not as cold as before.
- Warmer climate has sparked an onset of epidemic
diseases - Water in summer is no longer as clean as before.
- Tibetan plateau is home to an expanse of glaciers
measuring 59,425 square kilometers. - But now the glaciers are shrinking by 131 square
kilometers yearly. -

11The melting glaciers impacts on water
- As glaciers melt, river runoff will initially
increase in winter or spring but will eventually
decrease as a result of loss of ice resources - This is likely to be unfavourable for downstream
agriculture - This could seriously affect half a billion people
in the Hindu-Kush-Himalaya region and a quarter
billion people in China who depend on glacial
melt for their water supplies.
12High dependence of major South Asian countries on
transboundary surface water

14Experts Opine that--
- Glacier change is an indicator of climate change
- Regular monitoring of glaciers including mass
balance is necessary - Monitoring of glacial lakes and adaptation and
mitigation measures for potentially dangerous
glacial lakes are required. - The development of a dynamic and regional
database on glaciers and glacial lakes will
greatly enhance the understanding of global and
regional climate trends. - Regional cooperation is necessary for systematic
research on snow and ice and water
15Impacts on Human Life
- The most marginalized (mountain communities and
ethnic minorities, etc.) and vulnerable groups
will suffer the most from. - Impact on biodiversity and affect on peoples
diet, nutritional status and nutrition related
health problems. - Infectious diseases, particularly the insect
vector-borne diseases such as malaria, dengue
fever and Japanese encephalitis are sensitive to
the impact of climate change. - Agriculture, particularly rain-fed agriculture is
highly sensitive to climate change. - Increase in temperature may reduce the crop
yield, particularly of cereal crops, and
therefore cause food shortage.
16Geopolitical and Environmental Security aspect
- Conflict over possession of natural resource.
- Socio-political and economic unrest.
- Migration en masse.
- Regional disintegration.
- Inter and/ or Intra-state conflict.
- Loss of biodiversity.
- Loss of human habitat.
- Extinction of species.
- From Nuclear Winter to Carbon Summer.
17Affects of global warming in Bangladesh
- If nothing is done to curb emissions, sea levels
could climb more than three feet. - 15 of Bangladesh could be under water if sea
water rises 1 feet. - The mangrove forests of Sundarban islands, a
world heritage site, the Bengal tiger and
hundreds of bird species may disappear. - Tens of millions of Internally Displaced
Persons(IDPs). - Bangladeshs food supply is already threatened by
flooding due to melting glaciers in some areas
and droughts due to heat in others. - Environmental issues can also fuel violence and
political unrest.

18Sea Level Rise Worst Case Scenario
19Recommendations
- Need to reduce scientific uncertainty.
- Reduce risk from seasonal and flash floods.
- Support community-based adaptation and disaster
management. - Need to promote regional co-operation in water
resource management. - Need to do policy advocacy at national and
regional levels.
