This has been a challenging year. I don't have the exact status, except that I think, generally, agriculture is increasing its yields. The key thing we have to do—we've had the discussion about biodiversity—is sustainable intensification.
We can't really produce.... All of the good farmland in the world is more or less under cultivation right now. If we can't find ways to grow more food on that existing land base, hungry people will cut down forests and they will drain swamps, wetlands and other habitat.
We're progressing to probably achieve the increase in food production that will be required by 2050, but we have to be very careful about how we do it, so that we don't affect other important environmental imperatives.
