Slide16: Resource poor farmers may, however, be more vulnerable due their limited capacity to adapt because of a lack of financial, institutional and technological capacity Impact Assessment on Regional Production: Impact Assessment on Regional ProductionFood Demand in India: Food Demand in India Can India meet its food requirements?

India Source: Gadgil et al., 1999,Recent Changes in Weather: Recent Changes in WeatherSlide29: Trends in Rabi Temperature Maximum MinimumSlide30: Trends in Kharif Temperature Maximum MinimumSlide31: Climatic Variability in Uttaranchal Seasonal / Annual scale trend analysis of long term rainfall Source: Pant et al (1999) Trends expressed as cm / 100 years * Significant at 5%Slide32: Decline in Yield of Rice and its Relation to Weather at Ludhiana Decline in yield is apparently also related to decrease in radiation and increase in minimum temperatureAdaptation Strategies: Adaptation Strategies Adapting to Global Warming by Changed Management and Breeding: Minimum and maximum changes refer to the impacts under different scenarios, new management refers to a longer duration variety and one week early planting Adapting to Global Warming by Changed Management and BreedingUncertainties: Uncertainties Magnitude of change Technologies Crop and pest responses Adaptation options Policies Methods of assessmentSlide36: Uncertainty of Response to Global Climate ChangeConclusions: ConclusionsSlide38: On an aggregated level, no significant impact provided pests are under control. Some regions and crops may show slight negative effect, particularly rainfed rabi crops. Recent changes in weather indicate a warming trend at many places. This could be partly related to observed yield stagnation/decline in intensive cropping systems. Direct Impacts of Climate Change Short-termDirect Impacts of Climate Change: Long-term Production of kharif crops may be less effected but may become more risky due to increased climatic variability and pest incidence and virulence. Production of rabi crops is more seriously threatened due to shortened crop growing period, and increased water stress. Partial mitigation possible by alternate management. Increasing future demand for food may have to be met in a scenario of reducing crop yields and with much higher levels of input usage. Direct Impacts of Climate ChangeSlide40: More serious due to increased incidence of extremes of the weather such as rainfall onset, duration and frequencies of drought and floods, and submergence of some coastal land. Diseases and insects strongly influenced by temperature and humidity. Any increase in the latter, depending upon their base value, can significantly alter their population, and associated yield loss. Quality of fruits, vegetables, tea, coffee, aromatic, and medicinal plants can be effected by small changes in temperature. Indirect effects of climate changeSlide41: Agriculture in India is at present undergoing rapid transformation due to changing demands, markets and agricultural technologies. Pace of these changes is likely to increase in near future These changes may perhaps be more important than the climate change. Need to develop integrated (intra- and inter-sector) assessment procedures for impact assessment of global climate change Drivers of Agriculture in an Uncertain FutureSlide42: Projections Speculations Predictions Explorations Uncertainty about future Understanding of the integrated response of agro-ecosystems to climate change tweet delicious You do not have the permission to view this presentation.
