The topic of the moment is food sustainability, which by any other name, is how to feed an expanding world population. Part of the challenge is to improve the nutritional composition, the quality and the quantity of food from agricultural sources and to prevent the enormous post harvest losses in so many countries due to pests and to lack of transport infrastructure.

What is being discussed at the moment are the breeding technologies for grains and oil seeds; how to create new crops using traditional grafting and cross pollination techniques. Let us explore the future of genetically-modified crops which can give such huge increases at harvest; their safety in the food chain; How the wider use of these foods can be properly explained to consumers, is currently entertaining the minds of those much more knowledgeable than myself.

We do not want another fiasco as we had with irradiated foods when certain forms of food poisoning could have been wiped out at a stroke. except for the appalling publicity put out by misinformed people in the 1960s, and propagated by the mass media at the time: The ramifications are still with us today.

We have to continue with the steps being undertaken by the scientific community to create new test methods for the authentication of foodstuffs and their ingredients in the whole supply chain. We must find new analytical methods to prove provenance beyond doubt to assuage the curiosity of people encouraged by the mass media and by TV cooks.

We must find new methods to stamp out locusts, and to eradicate weeds and bacteria in our universal agricultural crops today, so that people can eat tomorrow. I go back to my mantra: Let the scientists get on with expanding out harvests, take the politicians, the quangos and the do-gooders out of the equation, so that our industry, the largest industry and the largest industrial employer in the UK, can help to provide good, nutritious food to feed the world in the coming years.
