Short Wave Folgen

Groundwater is responsible for about half of the water people use globally. It’s drying up. Hayes Kelman started noticing the family farm in western Kansas was slowly getting less water around the time he was in high school. Now, as an adult and co-owner of Kelman farms, he is acutely aware that there’s a problem: the aquifer he uses to water his crops is being drained faster than it can be refilled. If something doesn’t change, someday it will run out of water.Today, producer Berly McCoy dives into the state of the world’s groundwater and asks: What happens when people pull too much? And can the damage be reversed?Check out part 1 of our water series, Day Zero: When the wells run dry.Interested in more water science?

In honor of World Water Day, Short Wave is exploring the ways water touches our lives. From increasing water shortages around the world, to how it’s affecting agriculture and aquifers. We’re starting with “day zero”: the day a city or place runs out of water. Cape Town, Mexico City, Chennai in India are just a few places that have come close to day zero events. Today, we talk to experts and hear from someone who lived in Cape Town during the crisis about why we’re overdue for rethinking our relationship to water. This is part of a whole series on the world's dwindling water supply. Check out the rest of the water series:Part 1: When the wells run dryPart 2: The world's groundwater problemPart 3: Freshwater's growing salt problemInterested in more science behind current events?

A multi-year megadrought in the Western U.S. has claimed untold populations of wild plants. Amid the conditions, some have survived. Scientists have produced a stunningly complete picture about how populations of one particular flower – the scarlet monkeyflower – made it through. In a new study published in the journal Science, a team of scientists spent decades studying and sampling select populations of scarlet monkeyflowers in California and Oregon. Through genetic sequencing, the team discovered that the populations that did best went through genetic changes in a short time period. This is known as rapid evolution. The team found that three of the populations that recovered the BEST adapted their stomata to open less, so they could conserve more water. Stomata act like a plant’s pores, managing gas exchange and water loss. This allowed the scarlet monkeyflowers to hunker down in the drought and survive. Interested in more stories about rapid evolution?
