An integrated farming system in Vietnam helps small-scale cattle farms by reducing emissions and improving livelihoods. By recycling waste into useful products like energy, fertilizer, and cattle feed, the system boosts agricultural productivity and income by up to 41.55%. Wastewater from the biogas tank can be treated for irrigation, and plant growth is sustained by nutrients from cattle waste. This approach shows that zero emissions can be achieved while supporting sustainable livelihoods for cattle breeding families.
