This document discusses the potential impacts of climate change on Bhutan's food security. It notes that Bhutan has a mountainous ecosystem that is vulnerable to climate change. Its agriculture is important for food security and livelihoods but is threatened by climate change. Specific climate hazards discussed are melting glaciers, landslides, and rising temperatures. These hazards can damage crops and infrastructure, cause food insecurity and health issues. Adaptation measures discussed include early warning systems, lowering glacial lake levels, soil conservation, water harvesting, and incentives for low emission technologies. The conclusion states that climate change is already affecting food systems and vulnerability, and greater impacts are expected in the future.

2. Bhutan overview
• Mountain ecosystem is more prone to the effects of
climate change.
• Divided into three distinct climatic zones:
-Southern foothills: hot and humid
-Central Inner Himalayas: Cool and temperate
-Northern Region : Alpine Climate. NEC (2000).
• Altitude ranging from less than 100m in the south to
more than 7,500m in the north .
• 20% of the land area is above 4,200m covered with
snow and ice
• Population is concentrated in the broad river valleys
3. • Climate is an important factor determining the production
of crops and if there is change, it poses a serious threat to
agriculture:
• Agriculture?
Agriculture is important for food security
• “Food security exists when all people at all times have
physical or economic access to sufficient safe and nutritious
food to meet their dietary needs and food preferences for an
active and healthy life” FAO (1996).

Melting of
mountain glaciers-
-Loss of water reserves
-60% Bhutanese
revenue depends on
income from
hydropower
-Loss of lives
-Food insecurity
Eg. 94 households
affected and 16 metric
tones (MT) of food grain
washed away (UNDP,
2011).
-Installation of early
warning system
-Artificial lowering of
glacial lake levels
-reduced water volume
3.63m
Landslide
(change in weather
pattern– high rain
intensity)
-Damage to
agricultural crops ,
roads ,soil etc
E.g.- June 29-12 SJ-
Trashigang highway
has remained
obstructed for 3 days
-Loss of property and
live
eg. In 2013Tendu
landslide destroy house.
-20 decimals of land out
of 30 was washed away.
-River bank protection
-Soil conservation and
land management
Increase in
temperature-1°C
from 2010 to 2039
and by 2°C from
2040 to 2069
-Reduced water
available for drinking
and sanitation
-increase in
-Health risks-water-borne
diseases, food-borne
diseases
-Water harvesting.
-60% of forest cover
-Incentives for energy
saving devices and
low emission vehicles

5. Conclusion
• Climate change is real, and its first impacts are already
being felt. It will first affect the people and food systems
that are already vulnerable, but over time the geographic
distribution of risk and vulnerability is likely to shift.
Certain livelihood groups need immediate support, but
everybody is at risk.
• Climate change is already affecting food security and it is
expected to have even greater impacts in coming years

•This complex climate is due mainly to the country’s situation at the periphery of the tropical circulation in the north and on the periphery of the Asian monsoon circulation in the south. Summer monsoons typically last from late June through to late September, at times causing flash floods and landslides; monsoons generate approximately 70 per cent of the annual rainfall in Bhutan.
permanently covered with snow and ice, which form glaciers and glacial lakes
For a country like Bhutan, there will be more negative impacts as more than 70% of the population depends on agriculture and natural resources. Moreover, hydro electricity is the main source of revenue.
If agricultural production in the low-income developing countries is adversely affected by climate change, the livelihoods of large numbers of the rural poor will be put at risk and their vulnerability to food insecurity increased.
Climate models show a likely increase in Bhutan’s annual average temperature by 1°C from 2010 to 2039 and by 2°C from 2040 to 2069. But the temperature changes will likely influence overall rainfall patterns and increase droughts. (RGoB, 2011)
Recently, on August 16, 2004 a flash flood struck eastern Bhutan (Tashigang, Mongar and Lhuentse). This flood and the consequent landslides claimed 11 lives. A total of 29 houses were washed away, about 26 collapsed and 107 were partially damaged.
Weather events such as heat waves and stagnant air masses could increase the impact on human health as heat stroke, cardiovascular stress, and increase in respiratory diseases. Warmer temperature and disturbed rainfall patterns could increase in the number of vector- borne disease, water-borne diseases, food-borne diseases, harmful algal blooms causing skin diseases, and poisoning and allergies caused by pollen.
