Another major source of food supply could emerge if the 30% of food produced that is now lost or wasted, could become available for human consumption. Source reduction and reprocessing of foods appears to be the best options to eliminate food waste or loss. One example of sustainable intensification and source reduction could be intensifying the harvest of vegetable crops to double the output with the same footprint. This will require consumers and food businesses to adapt their quality requirements and specifications. If the global food systems could change in this direction, the global food security will improve and be more resilient.
