Our earth releases several types of green house gases into the atmosphere viz., carbon dioxide, nitrous oxide, methane, chlorofluorocarbon etc. Rice is a prime food crop in the Asian countries which fulfil the food security. Methane is one among the greenhouse gases which usually emitted from low land rice field. Methanogen survive in the absence of oxygen and usually releases methane from irrigated rice ecosystem. Methanotroph are aerobic group of organism that require minor amount of oxygen to survive. Rice ecosystem is the ideal ecosystem for the survival of methanogens and methanotrophs. With this background methanotrophs were isolated from four different location of cauvery delta zone. Cultures were confirmed through methane monooxidase activity. Methanotroph isolates were mass multiplied and bioinoculants were developed.

This study attempts to highlight the comparative economic and environmental advantages of solar powered irrigation in terms of cost, energy and carbon footprint over the existing electric operated pumping system in rice cultivation. Multi-stage and snowball sampling methods were used in this study. This study was conducted in Villupuram district of Tamil Nadu purposively, as the district has the largest number of energized pumps adopted for irrigation in the state and it will be considered as a second stage. The total sample size of 90 was allotted with a quota of 45 each under electric operated well (EOW) and solar operated well (SOW) category. The cost of irrigation water, energy and carbon footprints were indirectly assessed in this study using some imputation procedures. The hours of irrigation were higher in the case of solar due to lesser horse powered motors and energy rationing is not the binding constraint in SOW unlike EOW. The per liter cost of water output was higher in the case of electric with subsidy and same was higher in the case of solar in without subsidy scenario comparisons. The hours of pumping and imputed energy consumption were higher for rice in the case of SOW compared to EOW. The energy consumption per ha decreased with increasing HPs both in the case of SOW and EOW due to economies of scale operation. The inclusion of social carbon cost in the economic analysis showed that the net income in SOW was higher without any compromise in rice production. In with social carbon cost / benefit scenario, the irrigation cost share was lesser in SOW compared to EOW. Hence it was construed that the SOW internalize the carbon footprints and serve as an important mitigating tool in confronting upcoming climate change risks. The policy makers must pay attention in promoting the subsidized SOW in agriculture, considering the negative and positive externalities involved in these two sources of irrigation.
