to tackle Adverse Impact of Global Warming on Food Crops

Action-Plan to tackle Adverse Impact of Global Warming on Food Crops

 in association with the increase in concentration of green house
 in the atmosphere is one of the reasons for the increase in extreme
weather events. Due to global warming agriculture sector is likely to be
affected and climate change is expected to impact yields of agriculture crops
in a business as usual scenario. 

What does the
Study shows?

  • According to the simulation
    studies using integrated modelling framework, it is seen that rain-fed rice yields in
    are projected to reduce marginally (<2.5%) in 2050 and 2080 scenarios
    while irrigated rice yields are projected to reduce by 7% in 2050 and 10% in
    2080 scenarios
  • Climate change is projected to reduce wheat yield by 6-25%
    towards the end of the century
    with significant spatio-temporal variations. 
  • Climate change in 2050 and 2080 scenarios is projected to reduce the kharif
    maize yields by 18 to 23%
  • Kharif groundnut yields are projected to be
    increased by 4-7% in 2050 scenarios where as in 2080 scenario the yield is
    likely to decline by 5%
  • Future climates are likely to benefit chickpea with
    increase in productivity (23-54%).

What are the various steps taken till now?

  • During XII
    Plan (2012-2018)
    , more than 400 climate resilient germplasm lines have been
    identified and 58 genotypes characterised with high water and nutrient use
    efficiency by Indian Council of Agricultural Research (ICAR).
  • National
    Mission for Sustainable Agriculture (NMSA)
    one of the missions under National
    Action Plan on Climate Change (NAPCC)
    aims to evolve and implement strategies
    to make Indian agriculture more resilient to the changing climate.
  • National Food
    Security Mission (NFSM) programme
    is implemented in the identified districts
    across the country with the objective of increasing food-grain production
    through area expansion and productivity enhancement, restoring soil fertility
    and productivity at individual farm level and enhancing farm level
  • ICAR
    has launched a flagship network project National Innovations in Climate
    Resilient Agriculture (NICRA)
    • The NICRA
      aims at
      strategic research on adaptation and mitigation, demonstration of
      technologies on farmers’ fields
      and creating awareness among farmers and other
      stakeholders to minimize the impacts of global warming on agriculture. 
    • Under
      this project, large number of indigenous genetic resources and improved crop
      varieties of pulses
      (black gram, green gram, pigeonpea, chickpea) and cereals
      (rice and wheat) are screened for major abiotic stresses like drought and heat
      to identify superior cultivars for large scale adoption in farmer’s fields
      genetic materials for cultivation at farmers field. In the process number of
      genetic materials including improved varieties were identified, some of which
      are already in the farmer’s fields. 
    • Besides, location specific NRM technologies
      are being demonstrated under Technology Demonstration Component of NICRA in 151
      climatically vulnerable districts
      to achieve climate resilient
