• 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.
