Farming systems approaches invariably include crops, fisheries and live stocks and their interactive relationship within the households specially in the small and marginal household in the South Asian context. This has the uniqueness in addressing the household food consumption and nutrition. The development and fast tract diffusion of climate smart technologies can address and reduce the household vulnerabilities. We can reduce the livelihood vulnerability in climate vulnerable areas through reducing the sensitivity of any crop, fish or livestock technologies. These practices will also increase the adaptive capacity of the small households. This can be described by the following equation as described by B.M. Simpson (2016):
Livelihood vulnerability = (Exposure × Sensitivity) – Adaptive capacity
