Sustainable production of animal-source food requires tailored solutions
The global demand for food, and particularly animal-source food, increases. Expanding the agricultural area for livestock production is not desired. How much can livestock production increase on the existing area? This research presents a new method, based on yield gap analysis, and provides insight which measures are most effective to increase the production of feed crops and livestock sustainably in different parts of the world. Model results provide insights in the biophysical factors constraining production, such as heat stress, feed quality, feed availability, and cattle management, and water and nutrient availability for feed crops. This allows to identify tailored interventions to increase the production of animal-source food sustainably. Integrating these insights with knowledge on socio-economic effects of interventions and animal welfare allows to design more efficient and sustainable crop-livestock production systems.
