12. Vulnerability
Vulnerability to climate change is the risk of
adverse things happening
Vulnerability is a function of three factors:
Exposure
Sensitivity
Adaptive capacity
13. Exposure
•Exposure is what is at risk from climate
change, e.g.,
– Population
– Resources
– Property
•It is also the climate change that an
affected system will face, e.g.,
– Sea level
– Temperature
– Precipitation
– Extreme events
14. Sensitivity
• Biophysical effect of climate
change
– Change in crop yield, runoff,
energy demand
• It considers the
socioeconomic context, e.g.,
the agriculture system
• Grain crops typically are
sensitive
• Manufacturing typically is
much less sensitive
15. Adaptive Capacity
• Capability to adapt
• Function of:
– Wealth
– Technology
– Education
– Institutions
– Information
– Infrastructure
– “Social capital”
• Having adaptive capacity does
not mean it is used effectively
16. Vulnerability is a
Function of …
• More exposure and
sensitivity increase
vulnerability
• More adaptive capacity
decreases vulnerability
• An assessment of
vulnerability should
consider all three
factors
17. Adaptation
“adjustment in natural or human
systems in response to actual or
expected climatic stimuli or their
effects, which moderates harm of
exploits beneficial opportunities”
(Third Assessment Report, Working
Group II)
Includes “actual” (realized) or
“expected” (future) changes in
climate
18. Adaptation (continued)
Two types of adaptation
Autonomous adaptation or reactive adaptation tends to be what
people and systems do as impacts of climate change become
apparent
Anticipatory or proactive adaptation are measures taken to
reduce potential risks of future climate change
19. SL framework: Determinants of adaptive capacity
Livelihood Examples
resources
Human Knowledge, Skills
Social Women’s savings and loans groups, farmer-
CBOs
Physical Irrigation infrastructure, seed and grain
storage facilities
Natural Reliable water source, productive land
Financial Micro-insurance, diversified income sources
Policies, institutions and power structures
21. Indian poverty
• Poverty is widespread in India, with the nation
estimated to have a third of the world's poor.
According to a 2005 World Bank estimate, 41.6%
of the total Indian population falls below
the international poverty line of US$ 1.25 a day
(PPP, in nominal terms 21.6 a day in urban areas
and 14.3 in rural areas).[1] A recent report by the
Oxford Poverty and Human Development
Initiative states that 8 Indian states have more
poor than 26 poorest African nations combined
which totals to more than 410 million poor in the
poorest African countries.[2]
22.
23. What is being done and how effective is it?
1. Communities continuously finding better options to reduce their
vulnerability
2. Few responses decrease the sensitivity of the system
3. Majority are short-term fixes - reduce vulnerability temporarily but
decreases the resilience of the system
24. Climate Changes
in India
• Increase in surface
temperature by 0.4
degree C over the
past century.
• Warming trend
along the west
coast, in central
India, the interior
peninsula, and
northeastern India.
25. Climate Changes in
India
• Cooling trend in
northwest India and parts
of South India.
• Regional monsoon
variations: increased
monsoon seasonal
rainfall along the west
coast, northern Andhra
Pradesh and North-
western India, decreased
monsoon seasonal
rainfall over eastern
Madhya Pradesh, North-
26. Climate Changes in India
• Observed trends of multi-
decadal periods of more
frequent droughts, followed
by less severe droughts.
• Studies have shown a rising
trend in the frequency of
heavy rain events and
decrease in frequency of
moderate events over
central India from 1951 to
2000.

27. Climate Changes in
India
• Records of coastal tide
gauges in the north
Indian ocean for the
last 40 years has
revealed an estimated
sea level rise between
1.06-1.75 mm per year.
• The available
monitoring data on
Himalayan glaciers
indicates recession of
some glaciers. 27

37. WATERSHED DEVELOPMENT
PROGRAMME (WDP)
Improve and sustain productivity and production
potentials of the dry/semi-arid regions of India
through adoption of appropriate production and
conservation technologies.
Meet the needs of local rural communities for
food, fuel, fodder and timber. Improve all types
of lands, i.e., Government, Forest, Community
and Private Lands falling within a watershed.
38. WATERSHED DEVELOPMENT
PROGRAMME (WDP)
WDPs, in short: A holistic approach to improve and
develop the economic and natural resource base
of dry/semi-arid/fragile regions. In a watershed
development program the watershed is the unit
for development rather than political or
administrative boundaries
39. WDP Activities
• i)Land Development: Levelling and
terracing, improving soil quality and
productivity; and watershed reclamation.
• ii)Water Development: Promote in situ water
harvesting and conservation, establish
percolation ponds and open
wells, tanks, small reservoirs, and improving
water quality.
40. WDP Activities
• iii)Enterprises/Activities: Evolve appropriate
farming systems, encourage a crop mix of
high value/high yield crops, social/agro-
forestry, other income-generating activities
like dairying, poultry-keeping, etc.
41. Some Illustrations of Benefits of
WDPs
• -Replacing seasonal/annual crops with agro-
silvi, agrohorti, silvi-horti; systems on hill
slopes/degraded lands. Benefits: reduce soil
erosion; arrest surface run-offs.
• -Training water to store excess water run-offs in
farm ponds/percolation tanks. Benefits: improve
groundwater recharge.
• -Construction of earthen or vegetative bunds or
barriers to surface run-offs in a watershed.
Benefits: help in moisture conservation.

45. MGNREGA
• 'National Rural Employment Guarantee Act'2005 (NREGA)
• Act guarantees 100 days of employment in a financial year to
every household
• a social safety net for the vulnerable groups and an
opportunity to combine growth with equity
• Structured towards harnessing the rural work-force, not as
recipients of doles, but as productive partners in our
economic process
• assets created result in sustained employment for the area for
future growth employment and self-sufficiency
• Operationalised from 2nd February, 2006 in 200 selected
districts, extended to 130 more districts in 2007-08.
• The remaining districts (around 275) of the country under the
ambit of NREGA from 1st of April, 2008
46. Agriculture
• India ‘s population is 1.21 billion in 2011. 67% are rural.
Majority are in agriculture.
• Importance of agriculture in Indian economy. Although it
contributes only 15% of GDP, the share of workers is about
55%.
• Marginal and small farmers dominate
• Major crops are rice, wheat, maize, coarse
cereals, groundnut, cotton, sugarcane, fruits and vegetables
• 60% of cultivated area is rainfed as only 40% of area is
under irrigation.
• Rural poverty is 41%in 2004-05.
• Agriculture is a ‘State Subject’. In other words, the policies
of provinces are also important
47. Climate Change / Variability
in Semi-arid regions
Precipitation is less than
potential
evapotranspiration.
Low annual rainfall of 25
to 60 centimeters and
having scrubby vegetation
with short, coarse grasses;
not completely arid.
48. Climate Change / Variability in Semi-arid regions
Climate Variability and extremes are an
expected characteristic of semi-arid lands.
The people vulnerable to droughts, which
trigger frequent subsistence crises
Increasing crop
failures, dislocation, famine, poverty, increases
stratification and the social inequities.
49. Major challenges of Agriculture

from natural sources
Natural resources are threatened by stresses

Agriculture & natural resource based livelihoods

Rural poor do not have resources to cope

Stress-tolerant, climate-resilient varieties of
seeds, drip irrigation, zero-tillage, raised-bed
planting, laser-levelling, Systems of Rice
Intensification (SRI), can build adaptive
capacities to cope with increasing water
stress, providing “more crop per drop”.

66. Biocharculture
Biocharculture is the process of using Biochar,
including cultivation of crops
• Biochar is the charcoal produced from carbonaceous source
material. Sink for atmospheric carbon dioxide in terrestrial
ecosystems
• Biocharculture is one of the means to integrate for sustainable
cultivation and carbon sequestration.
• Biochar is usually produced at around temperatures 300 to 600
degrees centigrade for example as found in the common biomass
cook stoves.
• Because of its macromolecular structure dominated by aromatic
C, Biochar is more recalcitrant to microbial decomposition than
uncharred organic matter
