exhaustively reported primer on the world\u2019s water problems and dives into potential fixes, including agricultural remedies, policy changes, tech innovations and at-home solutions like rainwater harvesting.<\/p>\n\n\n\n<p>\u201cThe world isn\u2019t running out of water \u2014 people are,\u201d Smedley writes. He travels to the Hoover Dam in the American Southwest to see the <a href=\"https:\/\/www.sciencenews.org\/article\/largest-lakes-drying-shrinking-climate\">low water levels<\/a> at Lake Mead (<em>SN: 5\/18\/23<\/em>). He visits the Middle East, stopping by Jordan\u2019s Karameh Dam, where the impounded water has become too saline for irrigation. Closer to home, he tours Europe\u2019s largest artificial lake, northern England\u2019s Kielder Water, which was constructed during the late 1970s in anticipation of a water demand that petered out within about a decade of completion. It\u2019s the southern half of the country that has become water-stressed.<\/p>\n\n\n\n<p>Such megaprojects highlight how \u201cwater crises are usually caused by all-too-human mismanagement, not climate,\u201d Smedley writes. But climate change is certainly making things worse, he adds: \u201cAs climate change bites, precipitation patterns change.\u201d For instance, the warmer atmosphere holds more water vapor, a greenhouse gas that exacerbates warming and fuels massive storms that unleash devastating floods.<\/p>\n\n\n\n<p>Flooding can make water pollution worse. Runoff from storms carries extra nitrogen and phosphorus from farms. A \u201cpoonami\u201d of <a href=\"https:\/\/www.sciencenews.org\/article\/cow-cattle-pee-potty-training-bathroom-pollution-ammonia\">livestock-sourced manure<\/a>, which contains those elements, contaminates freshwater supplies, as do fertilizers (<em>SN: 9\/14\/21<\/em>). Some agrochemicals, Smedley writes, have been tied to increases in pediatric cancer cases.<\/p>\n\n\n\n<p>Changes to farming practices, just some of the solutions Smedley explores, could mitigate pollution, water scarcity and potentially flooding all at once. No-till agriculture results in root systems, webs of fungi and burrowing bugs that maintain a spongy soil that sucks up water. Because they hold more water, these fields can better weather dry spells. Their soil structure helps them resist <a href=\"https:\/\/www.sciencenews.org\/article\/soil-erosion-rate-us-midwest-unsustainable-usda\">erosion<\/a>, minimizing runoff (<em>SN: 4\/12\/22<\/em>). They also need far less fertilizer because fungi and other microbes, in conjunction with cover crops planted between growing seasons, maintain and return nutrients to the soil. England\u2019s water woes \u2014 shortages are an issue despite the reputation for heavy rainfall \u2014 could be solved through no-till farming alone, Smedley\u2019s reporting reveals.<\/p>\n\n\n\n<p>As for the interred underwear, after a couple months, Smedley and the farmer unearthed dusty, holey pants from the organic field, whereas the conventional farm produced dirty-yet-wearable ones. The no-till field, unplowed for decades, turned up a \u201cbedraggled mess\u201d of soil, fungal residue and purple patches, along with a millipede that leaped from the scraps and scurried away. <\/p>\n\n\n\n<p>Smedley packs his book with sometimes funny, often serious insights that people can apply to their lives. Most of the \u201cwater footprint\u201d of people in the Western world, for example, comes not from tap water used for bathing, cooking and cleaning, but from the water that goes into making the products we consume. Depending on where and how it\u2019s grown, and the specifics of the calculations, tossing a browned avocado can waste 273 liters of water. A single steak can cost 2,000 liters. \u201cIf you\u2019re wearing a T-shirt made from cotton grown in Egypt,\u201d Smedley writes, \u201cyou are, in a sense, wearing water from Egypt.\u201d <\/p>\n\n\n\n<p>Given all the water we waste, Smedley notes, small changes can make a big difference. \u201cThe \u2018last drop\u2019 doesn\u2019t mean waiting for the water to run out,\u201d he explains. \u201cIt means valuing every last drop as precious.\u201d<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<p><em>Buy<\/em> <a href=\"https:\/\/bookshop.org\/a\/21798\/9781529058147\" target=\"_blank\" rel=\"noopener\">The Last Drop<\/a> from Bookshop.org.\u00a0Science News<em>\u00a0is a Bookshop.org affiliate and will earn a commission on purchases made from links in this article.<\/em><\/p>\n\n\t\t\t<\/div>\r\n<br>\r\n<br><a href=\"https:\/\/www.sciencenews.org\/article\/world-water-problems-book-solutions\">Source link <\/a>","protected":false},"excerpt":{"rendered":"<p>The Last DropTim SmedleyPicador, $29.99 A journalist and a farmer visit three fields with different styles of cultivation \u2014 conventional, organic and no-till \u2014 to bury cotton underwear in each.
