The Environmental Food Crisis report warns that unless action is taken, up to 25% of the world’s food production may become lost due to environmental breakdown by 2050.
However, food supply can be improved by enhancing food energy efficiency.
Food energy efficiency is the ability to minimize the loss of energy in food from harvest potential through processing, to actual consumption and recycling. By optimizing this chain, food supply can increase with much less damage to the environment.
For example, developing alternatives to the use of cereal in animal feed, such as by recycling waste and using fish discards, could sustain the energy demand for the entire projected population growth of over 3 billion people, and a 50% increase in aquaculture.
The report concludes that people need to get smart and more creative about recycling food wastes.
Among its recommendations is to raise awareness of the pressures of increasing population growth and consumption patterns on sustainable ecosystem functioning.
