Agronomic and Crop improvement strategies for Mitigation to Climate Change
Magan Singh, Principal Scientist, NDRI, Karnal
Inter
Governmental Panel on Climate Change (IPCC) refers to any change in climate
over time, whether due to natural variability or as result of human activity. In
present times increased pace of climate change due to inadvertent anthropogenic
disturbances increased concentration of green house gases (GHGs) viz.
carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O)
in atmosphere. These changes may culminate in adverse impact on human health
and the biosphere. The multi facetated interactions among the humans, microbes
and the rest of the biosphere are causing global warming across the globe along
with others cascading consequences in the form of delay in onset of monsoons,
shift in rainfall pattern and intensity, melting of ice, rise in sea level etc.
Recent observations noticed in increased in temperature, hot days, hot nights
and heat waves, increasing frequency of heavy precipitation etc. events are due
to climate change. Indian agriculture is highly prone to the risks due to
climate change. The Crop management, development of resource conserving
technology, diversified farming, enhancing N use efficiency, and crop
improvements etc. strategies could be the driving force for mitigation to climate
change.
