3. INTRODUCTION-
Agriculture represents a core part of the Indian
economy and provides food and livelihood activities
to much of the Indian population.
 Climate change is expected to impact agricultural
productivity and shifting cropping patterns.
The policy implications are wide-reaching, as
changes in agriculture could affect food security,
trade policy, livelihood activities and water
conservation issues, impacting large portions of the
population.

4. Changes in weather occurs due to
following factors -
ABIOTIC FACTORS: BIOTIC FACTORS:
• Ocean Currents Transpiration
• Solar Radiation Respiration
• Evaporation Photosynthesis
• Volcanic Activity Decomposition

5. Contribution of different sectors in
world to climate change –

6. Agriculture & Climate Change:
A two-fold relationship-
I. Agriculture as a contributor to Climate Change.
II. Impacts of Climate Change on Agriculture.
I. Agriculture as a contributor to climate change:
• Particulate matter & GHGs from land clearance by
fire & burning of residues.
• Emissions of CH4 and N2O; CH4: from rice &
livestock production, N2O from fertilizers &
manure.

7. II. Impacts of Climate Change on Agriculture-
 Greater loss expected in Rabi. Every 1°C increase in
temperature reduces wheat production by 4-5 million tons.
 Increased droughts and floods are likely to increase
production variability.
 Increased water, shelter, and energy requirement for
livestock; problems in milk production.
 May alter special demands and supply by impacting:
 –Food production
 –Stability and sustainability
 –Profitability
 –Trade & economy
 –Global financial Crisis.

8. Key adaptation strategies to Climate Change-
 Assisting farmers in coping with current climatic risks.
 Intensifying food production systems.
 Improving land and water management.
 Enabling policies.
 Strengthening adaptation research.
 New varieties: drought/heat resistant.
 New farm management practices.
Change in land use.
 Watershed management.
 Agri-insurance.

9. Agriculture as part of the solution –
 Increasing carbon sequestration through land
management .
 Rotations with cover crops, green manure
 Agro forestry
 Conservation tillage: Could reduce global CO2
emissions by 5-15%
 Organic farming (but limited benefits) :
Enhances carbon storage in soil.

10. CONCLUSION-
Global climate change is affecting Agricultural production
and so our survival. Indian agriculture is likely to suffer losses
due to heat, erratic weather, and decreased irrigation
availability. Research needs to find out appropriate
management practices to sustain the present level yield in
changed climatic conditions.
“Climate change”…Is it the Beginning of the end..??
The earth is heating..So is the environment..
Come Forward..
Join hands..
& Save Agriculture ,to sustain ourselves..
