Title : Economic and environmental impact of Arecanut based cropping system on the farming community of north eastern sub Himalayan tract of west Bengal

Abstract :

The agriculture system is under pressure due to climate change and its hurdle in achieving food, income, and environmental security with increasing rate of population. For this context it needs to improve the crop productivity per unit area through using available space vertically and horizontally along with other natural resources. Arecanut based cropping system (ABCS) is a perspective modern and alternative approach for sustainable productivity in horticultural crops for 85% small and marginal farming community of the North Eastern part of the country, not only providing greater economic return also playing better role in sustainable land use management and in better climate change mitigation through sequestering atmospheric CO2 in terrestrial ecosystem. Integration of different intercrops of annual and perennial nature were made for effective utilization of 70% left over land area and 40% of the incident solar radiation penetrating down within the canopy of the plantation. Various component crops of different ABCS models with their diverse carbon sequestration potential ultimately resulted into distinct total CO2 sequestered by one hectare model with different crop combination ranging from 280.77 to 313.96 t/ ha having lowest value under mono cropping situation with only arecanut (248.31 t/ha). The findings of the present study proved the weakness of monocropping and dictate towards adoption of high-density cropping system not only in terms of economic feasibility of the small and marginal farmers of North Eastern parts of West Bengal but also mitigating environmental issue related to emission of greenhouse gases. Economic assessment in different ABCD contributed better economic return.
