Rice cultivation through flooded cultivation method, often seen as a source of methane emissions, which contribute to global warming, does not release carbon into the atmosphere, a study by the Central Rice Research Institute (CRRI), a premier body under the ministry of agriculture, has stated. Instead, the study has said the tropical low land submerged ecosystem in mainly eastern India is a ‘net carbon sink not a carbon source’.

The low land flooded rice ecosystem has the capacity to store carbon in soil and can behave as net carbon sink, the study says. “Carbon inputs in rice field through photosynthesis, biomass and organic carbon added as manure exceed output, making paddy cultivation in eastern regions as carbon sinks rather than carbon emitters,” Pratap Bhattacharya, a senior scientist at CRRI told FE.

The findings of the study is expected to help agricultural scientists in fixing climate responsibility.
