A system dynamics model for improving value chains in sorghumdairy production systems

Doubling the farmer’s income is a hot debate among policy makers across India. To enhance the farm income, the scarce resources are to be integrated. This paper is mainly focused on the value chain development of sorghumdairy production system (crop-livestock interaction) that provides intervention to enhance the farm income. Sorghum is extensively cultivated in hot and arid regions which is used for human consumption and as feed for animals. It is largely used in the dairy industry as it serves as a good substitute for high priced concentrates and other feeds. This paper provides a methodology for value chain development in complex interconnected sorghumdairy production system by employing System Dynamics (SD). It quantifies multidimensional relationships between various value chain actors that profitably upgrade and commercialize the end produce. This methodological framework will ensure enhancing the farm income by producing the appropriate amount of produce in the supplyside.
