OUTLINE OF PRESENTATION
Background
Climate Change Impacts
Climate Change Adaptation
Awareness
Integrated Agromet Advisory Services based on weather forewarning
Human Resources Development
Future directions
Temperature increase by 2100 AD will be around 3°C
Wheat and rice production are likely to decline
The adverse impact of drought is more significant on food grainswhen compared to that of floods
Area under agriculture is declining
Crop productivity is stagnated sincelast one decade
Attributed to frequent occurrences of weather extremes

National action plan on climate change in India
Eight missions, for sustainable development.1. Solar energy2. Enhanced energy efficiency3. Sustainable habitat4. Conserving water5. Sustaining the Himalayan ecosystem6. Creating a “Green India”7. Sustainable agriculture, and 8. Establishing a strategic knowledge platform for
climate change
The Green India mission will enhance ecosystem services including carbon sinks to be called Green India
Sustainable agriculture mission intends making agriculture more resilient to climate change by identifying and developing new varieties of crops.
Price rise – Food crisis – Food security
