Achieving livelihood security and sustainability with a single enterprise is quite difficult for these farmers. The average size of agriculture landholding in India has reduced to 1.08 hectare in 2015-16 and there is no further scope for horizontal expansion of land for agriculture. So, vertical integration of various enterprises is need of the hour. Besides livelihood security, social, economic and environmental sustainability is also ensured by the integrated farming system. In this paper, the research work on some of the livestock based integrated farming systems which are in practice in northern India has been reviewed. Most of the studies indicated that integrated farming systems yield higher returns in comparison to single farming system and waste material is also better utilized. Keywords: Integrated farming, Manure, Sustainable development. India is predominantly an agricultural country and the livestock is an integral and indispensable component of our agricultural system. The majority of farmers in India are small and marginal farmers. According to 10 th agriculture census, small and marginal farmers holding less than two hectares of land, account for 86.2% of all farmers in India while, their share in total operated area is only 47.34% (Agriculture census, 2015-16). The average size of agriculture landholding in India is gradually shrinking and is declined to 1.08 ha in 2015-16 in comparison to 2.28 ha in 1970-71. In general, these small and marginal farmers practice subsistence farming where they want to produce a continuous, reliable and balanced supply of foods along with cash for basic needs and recurrent farm expenditure (Rani, 2015). It is difficult to achieve livelihood security and sustainability for these farmers with a single farm enterprise without turning to Integrated Farming Systems (Mahapatra 1992, 1994). Due to explosion of population and unplanned colonization, rapid fragmentation of land holdings and shrinkage in fertile cultivated land has occurred and there is no further scope for horizontal expansion of land for agriculture.
