As stated above, the food engineering community should help, as an important step to eliminate hunger, to reduce postharvest losses and processing losses and show ways to a better utilisation of waste and biomass, and of under-utilised raw materials and unconventional resources.
Since most of the problems occur in developing countries, all measures should take into account the technical potentials of those countries. It will be important to discuss how existing and new technologies are being introduced and extended into those areas. In my very personal view, a key role in this process has to be played by young, well educated food engineers with roots in those countries; they are close to the problems, know the people and have the knowledge base which is required to solve the problems. Again, a shift in paradigm away from strong support and advice from the outside to a transfer of responsibility to people born and living in developing countries, only in situations where outside help is vital, should that help be provided.
