AbstractOut of the concern of excessive use of agro-chemicals and declining state of soil fertility, crop productivity, degradation of land and water resources an NGO is pursuing efforts to promote ecological farming system against the present green revolution based modem agriculture. This study attempts to evaluate the sustainability of two production systems in terms of environmental soundness, economic viability and social acceptability. To measure the sustainability 14 indicators were developed and analyzed based on data collected through household survey, soil sample analysis, crop cutting survey, observations and discussion with key informants. The study finds considerable differences between two farming systems in terms of ecological sustainability, economic viability and social acceptability. Land use pattern, cropping pattern, soil fertility management, insect and pest management are found significantly better in the ecological farming system, because cropping diversification, mixed cropping, use of organic fertilizers, cultivation of legumes are relatively higher in this type of farming system, whereas cultivation. of HYVs paddy, area under monocropping, and use of chemical fertilizers are found significantly higher in the modem farming system. Soils, in terms of organic matter content, nitrogen, sulfur and zinc are better in the ecological village, whereas in terms of pH, and phosphorus are better in the modem village. Methods applied to control pest and diseases also significantly different in the two systems. Farmers in the modem village use pesticides, whereas farmers in the ecological village adopt integrated methods, including application of local herbal insecticides. Yield and financial returns found higher in the modem village, but the stability of yield and input self-sufficiency are higher in the ecological village. Economic returns without taking into account environmental cost are almost same in both villages, but value addition per unit of land is slightly higher in the ecological village. This indicates that the ecological village is better even from economic perspective. Ecological farming system is found relatively more labor intensive and less risk prone. Women's participation and farmers' access to information also found relatively better in the ecological village. Adequacy of food grain is relatively higher in the modern village due to higher yield of crops and relatively larger proportion of land under cereal production. However, there is not much variation in terms of food purchasing capability of farm households. It is evident that although yield and financial returns are slightly higher in the modern farming system, it uses much higher amounts of chemical fertilizers, pesticides, leading to negative externalities, including land degradation, water pollution, adverse impact on human and animal health. If these costs are taken into account, the ecological farming system appears much better. This study concludes that by promoting this type of farming government can achieve twin goals of environmental conservation and economic growth on a sustainable basis through changing government's present short-run growth oriented policy and reorienting the overall supports services, including research, extension, credit, market and infrastructure. Cropping diversification, integrated plant nutrient management, integrated pest management, reorientation of research, extension and support services and withdrawal of subsidy on chemical fertilizers and diesel are the major policy measures conducive to achieve the goals stated above.
