 Well, we do need to increase food production by 2050 because we have a growing world population, and that population is increasingly better off and is requiring or demanding more diversified diets. But in fact, the rate of growth of food demand is going to be less in the future than in the past. The real challenge for us is more on the supply side, because the way in which we increase food production in the past two to three decades is simply not going to be possible in the future. We don't have the land to expand into, energy is going to be more expensive, we need to be more careful with the environmental impact of increasing food production. So we do need to invest much more in agricultural research and also in the developing countries where most of the food increase, the increase in food production is going to take place. We need of course the accompanying measures, investments in rural infrastructure, marketing facilities in farmer education and advisory services. So there is a huge challenge to ensure that we have food security for all by 2050.
