Rice wheat cropping system has been widely adopted in Nepal since very long, but much less been
studied about the sustainability aspects of this practice. South Asian countries-, as well as other rice-growing
countries, have already experienced different ecological and environmental impacts of the long-term rice-wheat
system. Also,climate change seems to inflict the rice-based farming system to a varied extent depending
uponagroecological regions. In the meantime, the growth in yield of rice is plateauing to less than 1.5% although
productivity is well below other South Asian countries. With the heightening consumption of agrochemicals and its
subsequent impact on air, water and soil have to be taken into consideration. Rice-wheat system being heavy
consumer of nutrient and waterraises question about the sustainable consumption of resources. The increasing
dominance of hybrid varieties posses’ threat of extinction of local landraces of rice. Apart from environmental and
agronomic issues it also maybe affected by socio-economic issues of Nepalese farming families.Suraj Lamsal Naini Agricultural Institute, Sam Higginbottom University of Agricultural, Technology and Sciences, Prayagraj-211007, U.P,India
