Abstract

Aim: This study aims to focus on traditional agricultural practices which are gaining momentum around the globe as an energy efficient and sustainable approach in the changing climate condition. In this study, an attempt was under taken to quantify the energy use, green house gas emission and global warming potential of rice cultivated by traditional method in terraced low land.

Methodology: The data were collected through Focused Group Discussion (FGD) from farmers of the study area using the questionnaire. The sample size was calculated by Neyman method.

Results: Total input and output energy required for traditional rice production were 8513.0 MJ ha^-1 and 77356.88 MJ ha^-1, respectively. Energy use efficiency was calculated as 9.01. Total global warming potential (GWP) was 610.19 CO₂ eq ha^-1. In this study, the output and input carbon were found to be 2580.48 and 164.75 kg C ha^-1, respectively and the carbon efficiency ratio was 15.66. Energy productivity of this traditional method of rice production system was approximately 1.21 to 3.64 times higher than that of other rice production system.

Interpretation: Rice is the staple food of tribal's habited in the highland region of Eastern Ghats Odisha, India, and these tribal people mostly cultivate rice by traditional method. This traditional rice production system can be considered as an environmental friendly and sustainable agricultural system in this changing climatic condition, and this system is also economical than the conventional rice cultivation practices.
