How far is Integrated Farming System (IFS) helpful in sustaining agricultural production?
Approach · directive: “how far”
What it asks · Explain what IFS is and judge how far it sustains production: how it raises output, stabilises income and conserves resources, and where it falls short.
It asks 2 things — answer each
- Explain what an Integrated Farming System is
- Judge how far it sustains agricultural production: gains in output, income and resources, and its limits
Open with · An Integrated Farming System links crops with livestock, fish, poultry, bees or trees on one holding so that the by-product of one enterprise feeds the next; with small farms of up to 2 ha holding 'the key' to India's food security (Agriculture Ministry, 2018), how far IFS sustains production matters.
Cover
- Recycling: residue becomes feed, dung becomes manure or biogas, pond silt returns to fields; purchased inputs fall and soil health improves.
- Year-round use: land, water and family labour work through the year, raising output per hectare.
- Income and risk: ICAR's IFS models show a demonstrated potential to raise farm income 2-3 times; Bihar, Karnataka, Kerala, J&K and Tamil Nadu have put them in State Plans (PIB, 2021).
- Research backing: ICAR with 25 agricultural universities developed 45 IFS models for 23 states and one UT (2018); Kerala scaled them to over 37,000 farmers' fields in 14 districts (2024).
- Resilience and nutrition: mixed systems buffer drought and flood losses and diversify the family diet.
- Limits: capital, skills, labour and market links; gains vary by land, water and location; it complements, not replaces, gains in the main cereal belts.
- Way forward: bankable IFS projects (31 prepared by ICAR for 22 states) financed through credit, with extension and market links.

An Integrated Farming System links crops with livestock, fish, poultry, bees or trees on one holding, so one enterprise's by-product feeds the next. With small farms of up to 2 ha holding 'the key' to food security (Agriculture Ministry, 2018), its reach matters.
How IFS sustains agricultural production
- Recycling: residue becomes feed, dung becomes manure or biogas, pond silt returns to fields; purchased inputs fall and soil health improves.
- Income and risk: ICAR's models show potential to raise farm income 2-3 times; Bihar, Karnataka, Kerala, J&K and Tamil Nadu have put them in State Plans (PIB, 2021).
- Research backing: ICAR developed 45 IFS models for 23 states and one UT (2018); Kerala has scaled them to over 37,000 farmers' fields in 14 districts (2024).
One small farm: crops; dairy; poultry and fish; agroforestry; biogas and compost
Where it falls short
- Entry barriers: capital, skills, labour and market links; gains vary by land, water and location; weak extension slows adoption.
- Scale: it complements, rather than replaces, productivity gains in the main cereal belts.
Way forward
- Credit and extension: ICAR's 31 bankable IFS projects for 22 states, for medium and short-term credit, with extension support and market links.
On the small farm that is India's norm, IFS turns subsistence into a stable, diversified livelihood: the evergreen revolution Swaminathan asked for, productivity without ecological harm.
