A much wider range of adaptations will be needed if food is to remain as copious, varied and affordable as it is today. These will include efforts to help crops withstand warmer temperatures, for example through clever crop breeding, advances in irrigation and protection against severe weather. Rich and poor countries alike should also make it a priority to reduce the amount of food that is wasted (the UN’s Food and Agriculture Organisation guesses that more than one-third is squandered). The alternative will be a world that is hungrier and more unequal than it is at present—and than it might have been.
That’s from The Economist‘s analysis last week of projected shifts in the distribution of crops around the world as a result of climate change. Needless to say, genetic diversity will be needed to do all those good things. Investors read The Economist, right?
