According to investigations around 15% of the world population today is undernourished. The increase in world population will strengthen the yet existing population–food imbalance. Besides increasing food supply and limiting population growth, drastically reducing the food losses which occur throughout food production, harvest, post-harvest, and marketing seems to be a viable option.
