Livestock production to feed the planet. Animal Protein: A Forecast of Global Demand Over the Next Years

Antonella Baldi, Davide Gottardo

Abstract


The world population will significantly increase by 2050, from the current seven million to more than nine million inhabitants and the highest rate of increase is expected in developing countries. The demand for animal products will follow the population growth and increase between 50 and 70%, although with differences between all regions. According nutritional recommendations, at least one third of the daily protein requirement should derived from animal proteins. Meat, fish, milk or eggs, rich essential amino acids, micronutrients and vitamins, should provide about 20g of 60g of total protein; however, the current level of intake should be reduced. In the next future, livestock sector will increase the productivity, without compromising the quality and the nutritional safety of the products, as well as the environmental protection and animal welfare. Considering the future population growth and the future food demand, different environmental implications on land use, natural non-renewable resources such as water, fossil fuels, minerals and agricultural land, and on the greenhouse gases (GHG) emissions should also be taken into consideration. Farming edible insect could be a possible solution to overcome the future population growth, the global demand for food, specifically for protein sources and the food waste reduction.
