Rice provides ~20% of human dietary energy and, for many people, a similar share their protein. cultivation, however, produces significant greenhouse gas (GHG) emissions, comparable to those from the aviation sector. The main GHG rice production is methane, mostly result conventional cultivation (CRC) keeping fields continuously flooded during crop cycle. There extensive evidence that alternate wetting and drying (AWD) substantially reduces methane emissions. AWD one component System Intensification (SRI), an agroecological approach management plants, water, soil, nutrients. This article reviews field studies measuring emissions associated with adoption SRI. review confirms both SRI offer substantial reductions in per hectare compared CRC. These benefits are, partly offset by increases nitrous oxide carbon dioxide. also show (but not AWD) improves yield therefore further kg rice. concludes while reduce kilogram rice, can simultaneously contribute food security addressing drivers climate change. Further investigation sequestration under different methods needed strengthen base.

Conservation Agriculture (CA) and the System of Rice Intensification (SRI) are both agroecologically-oriented production systems that support more productive, sustainable, resource-conserving farming, with synergies arising from their respective assemblages reinforcing agronomic methods. Application CA principles enhances growth, yield, performance crops grown under cropping system as well health resilience whole ecosystem. SRI practices create favorable conditions for development crop plants below- above-ground, can be enhanced by management. such reduced plant density m-2 elicit better phenotypic expression genetic potentials CA.. For these two to converge at field level, some plant, soil, water, nutrient management need modified or aligned. One adaptation is practice in on permanent, no-till, mulch covered raised beds, rainfall irrigation water furrows between beds furnishing controlling water; providing weed suppression improved recycling. rice benefit no-tillage, soil cover, diversified cropping, paddies beds. Several examples have shown this convergence feasible smallholding farmers larger-scale producers, also within a amenable considerable mechanization. This review article examines compatibility SRI, considering being utilized complementary ways. Further research experimentation needed identify assess appropriate capitalizing upon synergies.
