Integrated Farming System Model -

IFS treats the farm as an ecological-economic unit in which outputs from one enterprise serve as inputs for others (e.g., crop residues feed livestock; manure fertilizes fields; pond water irrigates crops). This circularity reduces external input dependence, improves resource-use efficiency, and increases farm-level income stability.

Poultry birds are often integrated to control pests in the fields. In a "backyard poultry" integration, birds scavenge on farm waste and insects, converting it into eggs and meat. Ducks can be integrated specifically with fish farming; their droppings fertilize the pond water to encourage plankton growth (fish food), and they help control snail pests in the fields. integrated farming system model

In a conventional farm, you buy inputs (feed, fertilizer) and sell outputs (grain, meat). In an IFS model, the waste of one enterprise becomes the input for another. IFS treats the farm as an ecological-economic unit

The Classic Cycle:

In this loop, input costs plummet, and waste is virtually eliminated. In this loop, input costs plummet, and waste
