Abstract
One of the biggest challenges of the twenty first century is
global climate change, which is due to increase in the G H G ’s (green
house gases) concentration in the atmosphere. Agriculture is one of the
most important causes o f global warming. It contribute both by
decreasing carbon sink in the form of clearing forest and also acts as
source by consuming products which are o f fossil origin. In order to
contemplate measures to reduce carbon emission from agriculture
sector, a clear knowledge o f sources that contribute for emission is a
fundamental requirement. In this direction the present study is
conducted.
occurring from the agriculture sectors o f Karnataka, India and
Afghanistan respectively. This is relatively less compared to other
countries like China and Canada. The reason for such low values is
less use of fossil fuel in farm operations in Karnataka and Afghanistan.
Among the fossil fuel based inputs used in, inorganic nitrogenous
fertilizers contribute 72 and 76% respectively in these two agriculture
systems. In Karnataka crops grown under irrigated system release
more carbon equivalents compared to unirrigated agriculture and
among the two major cropping seasons Kharif season’s carbon foot
print is more than Rabi crops. Among the major crops studied, carbon
foot print of Paddy was found to be highest and least was in case of
Bajra. The sustainability o f current system of agricultural practices of
in terms of input to output ratios for all the crops studied was good
except for Sunflower grown under unirrigated conditions. This can be
further enhances if the soil conditions are improved further by following
the recommended cultivation practices. Even though the carbon foot
print of Paddy is least compared to other countries, there are possibilities
reduce further by adopting aerobic system of cultivation.
It was found that about 5.90 and 0.85 TgCE/year is
