Researchers at Michigan State University designed some techniques using water retention membrane (a fancy word for plastic sheets, I think) buried under the soil to help retain water where the plants need it, without inhibiting their growth. It worked well, increasing yield to around 150% of normal. We’ll be needing more clever ideas like this in the coming years as global warming increases its impact on our way of life. Read more here.
