groundwater are one of the major factors influencing
climate change in the agricultural sector. In the context
of growing demand for adaption of pressurized
irrigation with electric pumps in South Central India,
the present study was undertaken to assess the carbon
dioxide emission (CO2 e) for different irrigation systems.
The crop water requirements and pumpsets
prevailing in the area were considered for estimation
of CO2 e. The estimation includes operational energy
consumption, well digging, installation and manufacturing
of the irrigation system as well as the pumpsets.
The irrigation systems used in major crops under
wells include surface (rice, maize, groundnut, vegetables
and sugarcane), raingun (maize, groundnut, vegetables
and sugarcane), sprinkler (maize, groundnut
and vegetables) and drip (vegetable and sugarcane).
The analysis indicated that the energy used in pumping
irrigation water made the highest contribution to
total CO2 e footprint, which ranged from 2.52 to
15.72 t/ha depending on the irrigation system. Sugarcane
crop showed maximum energy requirement
(17.27 MWh/ha) under surface irrigation system, contributing
15.72 t/ha CO2 e. Maximum reduction in
energy requirement and CO2 e was recorded in the
case of drip (11.52 MWh/ha; 10.48 t/ha) system followed
by sprinkler (12.58 MWh/ha; 11.52 t/ha) and
raingun (14.81 MWh/ha; 13.47 t/ha) under tube wells.
It was observed that among all the irrigation systems,
the drip system gave the lowest CO2 e indicating the
maximum climate change mitigation potential in the
irrigation sector of selected region under wells.
