Climate Change and Local Communities in the Nepal Himalaya

Global warming and climate change

• Climate change is now widely recognized as the major environmental problem facing the globe.

• UN Secretary-General Ban Ki-moon calls “the defining challenge of our age”.

• Evidence is building that impacts are being felt in the form of melting Himalayas and increased variability of temperature, rainfall and storms in virtually all regions.

• The Intergovernmental Panel on Climate Change (IPCC) Fourth Assessment Report (AR4) clearly states that it is no longer relevant to discuss whether the climate is changing but rather how much change we are committed to and how fast this will occur.

Global warming and climate change

• Climatic changes — such as

• shrinking glaciers, • variations in rainfall frequency and intensity, and • shifts in growing seasons and disease distributions —

are expected to have substantial, and largely negative, effects on food production, water supply and disease proliferation in many parts of the world.

Climate Change‘Warming of the climate system.’

Global Warming

• Increase in the earth's temperature refers to global warming, which in turn causes changes in climate.

• Earth's average temperature has risen about 1 degree C in the past 100 years and is projected to rise another 3 to 10 degrees C in the next 100 years.

Global Warming

• The most important of these being the emission of green house gases and the cleaning of natural vegetation.

• The climate is largely controlled by the flows of heat entering and leaving the planet and the storage of heat in the various compartments of the earth systems- ocean, land, atmosphere, snow/ice

Climate change is a natural process but excessive release of GHGs mainly CO2 has accelerated the change leading to ecological

uncertainties. Average per capita emissions in India are in the order of 1.0 t CO2 per capita per year (2005), while they are in the order of 10 t CO2 per capita per year in Germany and 20 t CO2/year in the USA.

Causes of Global Warming

• The global warming is caused primarily by carbon dioxide from burning coal, oil and gas.

• The second is methane (released from rice paddies, both ends of livestock, rotting garbage in landfills, mining operations, and gas pipelines).

Causes of Global Warming

• Third are chlorofluorocarbons (CFCs) released from refrigerator, air conditioner etc.

• Fourth is nitrous oxide (from fertilizers and other chemicals).

by:

Two important reports

• The Stern Review 2006• The 4th Assessment Report by the

Intergovernmental Panel on Climate Change (IPCC) 2007

• Both reports presented more and stronger evidence for the impacts of climate change on natural systems as well as on human activities in many parts of the world.

Consequences of Climate Change

• Receding snowlines• Hazy winter• Flash floods • Hotter summer months • Frequent landslides • Lake bursts (Glacier lake outburst flood) • Impacts are predicted to be especially large

for poor countries.

Nepal – a Mountain country

Tibet

IndiaNepal

Mountain countries such as Nepal are the most vulnerable to climate change.

Nepal is getting warmer at the rate of 0.06 degree Celsius per year i.e. 60 C in 100 years (GON-MOEST, 2003)

– High mountains warming faster (0.080 per year) than lower hills and plains (0.040per year)

Nepal is warming faster!

• Nepal is getting warmer at the rate of 0.06 degree Celsius per year i.e. 60 C in 100 years (GON-MOEST, 2003)

• Variability in mean temperatures is non-uniform both temporally and spatially.

• Examples – High mountains warming faster (0.080 per year) than

lower hills and plains (0.040per year)- 1990s and 2000s are globally warmer than previous

decades

Climate Change• Uncertainties in weather pattern• Erratic monsoon rains (departure

from normal pattern), examples– Higher maximum temperatures and

more hot days – More intense precipitation events– Changes in the timing of monsoon

onset and withdrawal– Higher minimum temperatures and

fewer cold days and frost– Reduced diurnal temperature range– Number of rainy days decreasing and

intense precipitation events are increasing

Impacts - Rural Communities

• People living in mountain ecosystem are particularly vulnerable to climate change as a result of:– Their high dependence on natural resources for

their livelihood– Comparatively higher exposure to extreme events– Widespread poverty and– Marginalisation

Vulnerable mountain community

Impacts - Rural Communities

• Less winter snowfall events and snow deposits

• Post-winter colder than usual due to snow or hailstorm with strong wind

• Glaciers are receding faster in recent years

• Potential to increase water related stress on rural communities

Braga: cirque glacier with debris

Impacts - Rural Communities

• Exposure to extreme events eg. from Manang

• Frequent snow avalanches leading to loss of lives and livestock

• Damage to infrastructures and livelihoods downstream,

• Landslide dam bursts

Impacts - Rural Communities• Locals of high

mountains complain of unusual rains causing collapse of their traditional houses made out of mud.

• Corrugated iron sheets are used to replace or repair traditional flat roofs.

Infrastructure Damage

Landslides and Soil Erosion

The traditional agriculture system is slowly weakening.

Agriculture: require more intense care and time

Looking for better options.

Erosion of traditional housing

Corrugated tin roof(Adaptation)

Drying water and irrigation sources

No snow fall means dry pasture

Low snow fall Disturbance in alpine system Less availability of alpine grasses High Incidence of livestock

diseases and Chances of higher depredation by snow leopard

Reducing the herd size or shifting the pasture.

Discuss at a community level

A case study• Climate change is a global phenomenon.• Have clear implications on planning and management of PAs.• ‘No action’ ‘Ke garne’ is no more an option.• Annapurna Conservation Area, Nepal• Working with the local communities

Think Globally Act Locally

Annapurna Conservation Area

• Largest protected area• High biological and cultural

diversities• Community-based

management• A major tourist destination• ICDP approach

– Successful integration of conservation and development issues

Energy source• Fuelwood was the principal

source of energy for domestic and tourism sectors.

• Consequences:– Deterioration in the quality

and quantity of forests.– Deforestations– Soil degradation– Erosion– Flooding– Increased CO2 emission– Decreased CO2 sink

• Improvement of livelihood standard

• Reduced carbon emission• Increased carbon sink• Avoided deforestation• Habitat improvement

Outcomes

Outcomes

Biodiversity Conserved

1. People have faced climate change and adapted to it since our species evolved.

2. Nevertheless, people have never adapted to climate change on the scale that we now face.

3. Existing coping strategies are not always adequate to respond to climate change.

1. Coping strategies need to be designed in the context of sustainable development.

2. Need to disseminate knowledge what we already know.

3. Develop capacity to cope with increased climate variability.

4. Communicating and raising community awareness

Save the Himalayas Campaign

Why this event?

• The Himalayas are shadowed in terms of the global climate debate.

• There is no unified voice of ‘Mountain States’.

• Hazard of ‘Melting of Himalayas’ will be far & wide.

• If we do not raise voice , who will?
