Enhancing the Adaptive Capacity of Indian Agriculture to Climate Change:

Opportunities and Constraints

Page 2: Enhancing the Adaptive Capacity of Indian Agriculture to Climate Change: Opportunities and Constraints

Agriculture led development in India

  Food production increased from 65 in 1960s to 230 million tons in 2008

  Land saved - more than 50 million ha   Calorie intake increased from 1900 to

2500 Kcal/capita/day   Poverty decreased in rural areas from

51% (in 1977) to 27% (in 2004)   Human development index improved

from 0.41 (in 1972) to 0.619 (in 2007-08)

Page 3: Enhancing the Adaptive Capacity of Indian Agriculture to Climate Change: Opportunities and Constraints

And yet problems persist

  1/4th of the world’s hungry   40% of the world’s malnourished

children and women   Lagging in meeting MDGs  Given a choice, 40% farmers would

like to leave farming (NSSO, 2005)

These impact assessments have uncertainties

  Possible errors in climate models, crop models and data used

  No link with change in future irrigation water availability

  No consideration of weather extremes   Future technological developments, (e.g.

in crop improvement), and socio-economic scenarios not considered

Page 11: Enhancing the Adaptive Capacity of Indian Agriculture to Climate Change: Opportunities and Constraints

Projected impacts of climate change on Indian agriculture

  Increase in CO2 to 550 ppm increases yields of most C3 crops by 10-20%.

  A 1oC increase in temperature may reduce yields of many crops by 0-7%. Much higher losses at higher temperatures.

  Productivity of most crops to decrease only marginally/remain unaffected by 2020 but decrease by 10-40% by 2100.

  Possibly some improvement in yields of chickpea, winter maize, sorghum and millets.

  Less loss in potato, mustard and vegetables in north-western India due to reduced frost damage.

Climate change may also provide new opportunities

  Apple yields in Himachal have decreased due to inadequate chilling

  Apple cultivation shifted upwards

  Farmers changed to vegetables earning more income

  New varieties with lesser chilling requirement being introduced

Adapting agriculture to climate change: Setting goals of adaptation

• Indian national agricultural policy aims a: • Growth rate of 4% per annum • Growth based on efficiency and conservation of resources • Growth that is inclusive and equitable

• Goals of adaptation • Producing more (diversified) food to meet demand • Stabilizing production in climate stressed seasons • Raising input use efficiency to address the increasing competition for land, water, capital, and labour settlements • Greater focus on poor

Page 14: Enhancing the Adaptive Capacity of Indian Agriculture to Climate Change: Opportunities and Constraints

Adapting to climate change by raising crop production: Large yield gaps in crops provide an opportunity

Current yield

Biophysical potential yield

Biological potential yield

Yield gap2: Limited by climate, soil, and irrigation

Yield gap1: Limited by crop management, pests, and risk management approaches

Demand 2020

Agronomic options can meet goals of adaptation in short-term

Page 16: Enhancing the Adaptive Capacity of Indian Agriculture to Climate Change: Opportunities and Constraints

Adaptation/mitigation options may not always be economically viable: Example of N use efficiency in rice

National Food Security Mission Aims to bridge yield gaps

  Launched in 2007 in 311 districts to raise production by 20 million tons:   Better seeds   Assured inputs-

nutrients, irrigation, machinery

  Farmers training   Demos

Climate change may limit the potential adaptation window of current technologies

Page 19: Enhancing the Adaptive Capacity of Indian Agriculture to Climate Change: Opportunities and Constraints

 70% of land under cultivation prone to drought

  12% of land (40 million hectares) to floods

  8% of land (8,000 km coastline) to cyclones

  A major disaster occurs every 2-3 years

  30 million people affected annually

Managing current and future short-term climatic risks is crucial

Short periods of drought can cause large yield losses: Sorghum in Rajasthan

Page 21: Enhancing the Adaptive Capacity of Indian Agriculture to Climate Change: Opportunities and Constraints

  Providing value-added weather services   Weak weather infrastructure; data protocols, storage, access and

dissemination   Promoting insurance for climatic risk management

  scientific and economically validated schemes; weather derivatives; awareness

  Facilitating community partnership in food, forage and seed banks   Technical know-how; capital costs; reduced acceptance if successive years

are risk free   Compensating farmers for environmental services

  Technical know-how; costs of production go up   Sharing experiences across similar regions

  Validation in new scenarios of development and climate risks

Adaptation to increasing climatic risks: Assisting farmers to cope with current climatic risks

Despite such policy responses, climatic risks still cause considerable loss

Key reasons   Widespread

poverty   Limited

human capital   Poor

governance including limited stakeholder analysis, and dissemination of knowledge

Conclusions

1.  Large yield gaps in all crops is an opportunity for meeting food demand in future even in the face of increasing climatic risks.

2.  In short-term, several options relating to technology transfer and adoption can help improve adaptive capacity. Later, better adapted genotypes will be needed.

3.  Climate change may provide new opportunities for growing crops in regions/periods not considered suitable earlier. Need to manage them.

4.  Problems related to poverty, governance, institutions, and human capital limit agriculture growth today and can also limit adaptation to increasing climatic risks.

Some observations on the proposed Mega Program on climate change

  Clear identification of stakeholders:   Farmers   Policy Planners   Industry (e.g. insurance, carbon markets)

  Stakeholders interest in adaptive capacity:   Understanding vulnerabilities of the region   Overall enhancement of adaptive capacity (not agriculture

alone)   Short-term action plans   Integrated, region specific solutions; and not by themes.

Page 27: Enhancing the Adaptive Capacity of Indian Agriculture to Climate Change: Opportunities and Constraints

  New partnerships are required:  Other science departments (earth

sciences, e.g.)  Development departments (e.g. irrigation

and disaster management agencies)   Industry (e.g. insurance, carbon

marketing)  Cooperatives (e.g. for food, seed and feed

banks)
