The eight week
free course, 3 hours per week, that I've just been doing with Futurelearn, was all about this topic - Global Food Security, or in other words, securing enough food to feed everyone. We looked at genetic modification, organics, local people developing their own local varieties of crop plants, systems in the West, systems in the poorer countries, obesity, malnutrition (which are not necessarily opposites as you can be severely malnourished but overweight, with your body trying to compensate for an appalling diet), politics, wars, greed for power, belief or otherwise in human nature.
We explored 'answers', but of course there is no single answer to feeding the World. A number of different approaches need to be worked on, everyone's favourite being for local people to be in control of their own food production, with support from others.
The course will be run again but I don't know when. It's something you can take part in to the exact degree you want to, use a false name if you wish perhaps, no photos, no comeback, just some interesting information.
