Global Challenge to Feed and Clothe the World’s Population in a Changing Climate
The CCRSPI Conference 2011

Price Volatility : Threat to Food Security
• Goal of restricting temperature rise to below 2 degrees Celsius
• For each 1 degree Celsius rise in mean temperature, wheat yield losses in India are likely to be around 6 million tonnes per year, or around $1.5 billion at current prices
Cancun Agreements (December 2010)Implications for Wheat Production
• IFPRI projects that rainfed wheat yields in South Asia will decrease by around 44% by 2050, if adaptation measures are not put in place
Common but Differentiated Impact

Unsustainable Consumption of Natural Resources
Expanding Ecological Footprint – Threat to Food Security
“Intensive cultivation of land without conservation of soil fertility and soil structure would lead ultimately to the springing up of deserts. Irrigation without arrangements for drainage would result in soils getting alkaline or saline. Indiscriminate use of pesticides, fungicides and herbicides could cause adverse changes in biological balance as well as lead to an increase in the incidence of cancer and other diseases, through the toxic residues present in the grains or other edible parts. Unscientific tapping of underground water would lead to the rapid exhaustion of this wonderful capital resource left to us through ages of natural farming. The rapid replacement of numerous locally adapted varieties with one or two high yielding strains in large contiguous areas would result in the spread of serious diseases capable of wiping out entire crops, as happened prior to the Irish potato famine of 1845 and the Bengal rice famine of 1942. Therefore, the initiation of exploitative agriculture without a proper understanding of the various consequences of every one of the changes introduced into traditional agriculture and without first building up a proper scientific and training base to sustain it, may only lead us into an era of agricultural disaster in the long run, rather than to an era of agricultural prosperity.”
M.S. Swaminathan Indian Science Congress, Varanasi, January 4, 1968
Sustainable Food Production : Early Warning
Green Revolution : Commodity-centred increase in productivity
Change In plant architecture, and harvest indexChange in the physiological rhythm-insensitive tophotoperiodismLodging resistance
Evergreen Revolution : increasing productivity in perpetuity without associated ecological harm
Organic agriculture : cultivation without any use of chemical inputs like mineral fertilizers and chemical pesticides
Green Agriculture : conservation farming with the help of integrated pest management, integrated nutrient supply and integrated natural resource management
If farm ecology and economics go wrong, nothing else will go right
From Green to an Ever-green RevolutionPathways
Mitigating Climate Change : Role of Terrestrial Carbon Banks
• Global net primary productivity (NPP) = 120 Gt/c/year
• Most of it is returned to the atmosphere through plant and
soil respiration
• If 10% of NPP is retained in the terrestrial biosphere (ie,
soil, plants, wetlands, mangrove ecosystems) , 12 Gt/c/year
can become part of a terrestrial carbon bank
• Increasing soil C pool by 1 ton c/ha/year in the root zone
can increase food production by 30 to 50 million tonnes

Faidherbia confers double advantages – carbon sequestration
and soil nutrient enrichment
60 years of research shows on each hectare, mature trees supply the equivalent of 300kg of complete fertilizer and 250kg
of lime. This can sustain a maize yield of 4 tons/ha

Community Food and Water Security System
Deepwater (floating) rice has three special adaptations:
i. ability to elongate with the rise of water levels;
ii. develop nodal tillers and roots from the upper nodes in the water
iii. the upward bending of the terminal part of the plant called 'kneeing' that keeps the reproductive parts above the water as flood water subsides.

National Biotechnology Regulatory Authority
The bottom line of our national
agricultural biotechnology policy should
be the economic well being of farm
families, food security of the nation,
health security of the consumer,
biosecurity of agriculture and health,
protection of the environment and the
security of national and international
trade in farm commodities”
