Consequences of
climate change:
12. 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-eastern India,
and parts of Gujrat and Kerala.
13. 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.
14. 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.
15. Vulnerability
Vulnerability to climate change is the risk of
adverse things happening
Vulnerability is a function of three factors:
Exposure
Sensitivity
Adaptive capacity
16.
17. 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
18. 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
19. 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
20. 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
21. 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
22. 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
24. In the life of a
farmer climate
Variability and
Extreme events
are more
important than
climate change
25. Vulnerability of poor in rural areas
Two-thirds of
households derive
income directly
from natural sources
Natural resources
are threatened by
stresses - Biotic &
Abiotic
Agriculture &
natural resource
based livelihoods at
immediate risk
Rural poor do not
have resources to
cope
26. 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
27. Rural Livelihoods - Resources
The livelihoods of the rural poor are directly
dependent on environmental resources.

33. Chennai
Floods
Source: India Today, 1st Dec 2015
According to Skymet data, during the month of November, Chennai
recorded a whopping 1218.6 mm of rain – three times its monthly
rainfall. The normal rainfall figures for November stand at 407.4 mm.
On the first day of December itself, Chennai recorded 374 mm and
the heavy rainfall will continue for few more days.
39. 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.
43. The drought-prone areas are confined mainly to the
peninsular and western parts of the country.
These regions suffer drought mostly due to the
cumulative effects of changing precipitation pattern,
excessive water utilization and ecologically
unsuitable agriculture practices
About 107 mha of the country spread over
administrative districts in several states is affected by
drought

Public involvement and capacity building
46. • Water in the tanks
• Conserving the trees
• Conserving fodder rather selling
• Food grains storage rather selling
1. Conserv
ing the
resources
• Prioritizing the sale in distress
• Continue to do any work which provides food or wage
• Stop risking through going for borewells / wells
• Reduce input costs
• Ensure drinking water for people and animals
• Food and fodder security
2. Coping
• Don’t sell your land
• Try avoiding getting credit – the interest rates would swallow you
• Stop unnecessary spending on the cultural / social events – festivals, marriages,
etc.
• Be united rather being in nuclear / dis-jointed families.
• Don’t cut / sell trees
• Take care of the health, so as to reduce the expenses on health
3. Not to
do
• Micro-irrigation practices
• Go for Sustainable and subsistence crops rather just commercial crops
• Social networks are useful be in the groups existing at various levels
4. Prepare
for the
adaptation
47. Watershed activities focus on vulnerability reduction

67. Why Drought Tolerant Plants
Drought tolerant plants are not limited to cacti and
succulents. There are thousands of species of beautiful
flowers, shrubs, vines and ground covers that are “un” thirsty
and could save more than 50% of the water used in a more
traditional landscape. Drought tolerant gardening also
involves sensible management like installation of drip
irrigation systems, timers, water sensors, and above all,
MULCH! Mulching and composting beds will improve soil
quality, reduce evaporation and encourage better water
absorption. Native plants, those plants which naturally grow
in our climate, need only about half as much water as most
exotic species. They also provide habitat for our native birds
and butterflies.
