Telangana: Cultivation of paddy creates higher CO2 emissions, says study | Hyderabad News – Times of India


HYDERABAD: One hectare of paddy production releases 30,671 kg of carbon dioxide (CO2) equivalent emissions into the atmosphere and impacts climate change, states a new study by Centre for Sustainable Agriculture (CSA) conducted in Telangana.
The study further said that the harmful methane (CH4) and nitrous oxide (N20) emissions are part of CO2 equivalent, according to international standards. A tonne of CO2 contains 32 tonnes of methane and 300 tonnes of nitrogen dioxide (N20).
Researchers said the study is important in the wake of recent Intergovernmental Panel on Climate Change (IPCC) report which said CO2 emissions must be reduced by 50% by 2030 from now to decrease the pace of climate change.
CSA completed this study to understand the ecological footprints of paddy cultivation. Paddy farming creates higher emissions than all other crops due to water retention in the field, which produces methane (20,223 kg per hectare) and field energy usage (6,240 kg).
According to agricultures scientist GV Ramanjaneyulu, who was actively engaged with the study, since paddy production has nearly doubled in seven years since Telangana’s formation, there is increased CO2 emission, and meeting the suggested objective set by the IPCC on lowering CO2 emissions is very challenging.
“What we computed is simply at the farm level, but if we add water retention at large dams and irrigation projects, as well as power use, the CO2 emissions will be significantly higher,” he said. There is a need to examine how much overall impact paddy cultivation has when compared to CO2 emissions created by vehicles and industry, he noted.
The study showed that wheat, groundnut, and tomato cultivation create considerably fewer carbon dioxide equivalent emissions per hectare than paddy cultivation.
The study was carried out in Jangoan, Vikarabad, Adilabad, and Siddipet districts.
