We Can Solve Water Scarcity in the U.S., New Study Says
The U.S., like much of the world, has the compounding problem of a growing population and an increased likelihood of drought due to the climate crisis. In fact, the Southwest is already in the throes of its worst drought in 1,200 years while Colorado and California are seeing how drought has turned their forests into tinder boxes. Now, a new study has identified ways to revamp how water is utilized to thrive in a time of water scarcity.
The study, titled "Reducing water scarcity by improving water productivity in the United States" was published Tuesday in Environmental Research Letters. The authors say that some of the most water-stressed areas in the West and Southwest have the greatest potential for water savings. The paper attributes nearly half the potential to simply improving how water is used in agriculture, specifically in growing the commodity crops, corn, cotton and alfalfa.
The researchers, led by a team from Virginia Tech, looked at realistic water usage benchmarks for more than 400 products and industries. The team of scientists pinpointed unrealized water savings in various river basins across the country.
"Nearly one-sixth of U.S. river basins cannot consistently meet society's water demands while also providing sufficient water for the environment," said Landon Marston, a Civil & Environmental Engineering professor at Virginia Tech University, in a statement. "Water scarcity is expected to intensify and spread as populations increase, new water demands emerge, and climate changes.
"However, improving water productivity by meeting realistic benchmarks for all water users could enable U.S. communities to expand economic activity and improve environmental flows. We asked ourselves the questions: if water productivity is improved across the U.S. economy, how much water can be saved and in which industries and locations?' Our study is the first attempt to answer this question on a nationwide scale, and develop benchmarks to inform future action."
The process of setting benchmarks provides various industries with a basket of options to make their water use more efficient. That makes the findings of the study less prescriptive and more amenable to how industry and populations can realistically adapt to decreased water availability, according to the researchers.
In fact, the range of options has the potential to improve water productivity so much that it could decrease the loss of water flowing through rivers in the West by six to 23 percent on average, according to the study.
"The agriculture and manufacturing sectors have the largest indirect water footprint, due to their reliance on water-intensive inputs, but these sectors also show the greatest capacity to reduce water consumption throughout their supply chains," said Marson, in a statement.
The demand for innovative ways to conserve water without sacrificing economic growth is peaking. In just 50 years, nearly half of the country's 204 water basins may fall short of meeting monthly demand, according to Harvard University. Since irrigation of crops accounts for nearly three-fourths of water use, a simple 2 percent reduction in consumption could prevent water shortages in several basins.
For that reason, activist organizations like The Nature Conservancy are teaming up with farmers to figure out how to improve infrastructure to reduce water consumption on all levels of the agricultural supply chain.
While the demand for water continues to grow despite its depletion, innovative solutions are possible, according to The Nature Conservancy.
The new study reaffirms that assessment.
"The agriculture and manufacturing sectors have the largest indirect water footprint due to their reliance on water-intensive inputs but these sectors also show the greatest capacity to reduce water consumption throughout their supply chains," the study authors wrote in their paper.

Jean-Marc Neveu and Olivier Civil never expected to find themselves battling against disposable mask pollution.
When they founded their recycling start-up Plaxtil in 2017, it was textile waste they set their sights on. The project developed a process that turned fabrics into a new recyclable material they describe as "ecological plastic."
Mounting Piles of Waste<p>It is not only the streets of Chatellerault where pandemic pollution is piling-up, but also the world's beaches and oceans. Once there, they can take up to 450 years to degrade and disappear.</p><p>Esther Röling, co-organizer of the annual Adventure Clean Up Challenge held on Hong Kong Island, has seen this waste firsthand. In October the sports challenge pitted teams against one another in a competition to remove trash from 13 hard-to-reach coastal areas around the city.</p><p>They find tons of both disposable and reusable masks, said Röling. "You wonder how it ended up there. Was it just thrown on the ground? Or was it in a garbage bag that broke open?"</p><p>Almost 10,000 kilometers away in Antibes on the sunny French Riviera, it's a similar picture. For the past few months, divers and clean-up volunteers working with an ocean clean-up non-profit called Operation Mer Propre have been collecting an increasing number of masks found on land and in the sea.</p><p>"Since the beginning of the lockdown when we started to count, we've reached 800, 900, [and now in total] 1000 masks," said co-founder Joko Peltier. </p><p>According to <a href="https://unctad.org/news/growing-plastic-pollution-wake-covid-19-how-trade-policy-can-help" target="_blank">UN estimates</a>, up to 75% of all coronavirus-related plastic could end up as waste in oceans and landfills.</p>
The Limits of Recycling<p>Yet not all are convinced the recycling of this waste is possible on a global scale. </p><p>"What those citizen groups are doing is really beneficial but once they collect it, it should just go to a landfill or an incinerator. They shouldn't necessarily expect it to get recycled," said Jonathan Krones, an industrial ecologist and visiting assistant professor of environmental studies at Boston College.</p><p>That's because mask recycling programs like Plaxtil are few and far between and most don't have the benefit of a readily adaptable production process. </p><p>Even in countries with solid recycling infrastructure, he says, the system is designed to separate out specific types of waste like bottles or cardboard.</p><p>"I imagine that it would be technically feasible to develop a separation process to filter out masks, but there simply aren't enough of them to make that economical," he said.</p><p>Collection is a big hurdle, he adds. Since each mask only weighs a fraction of a gram and they're scattered on roads or mixed with other trash, it is difficult and costly. </p><p>"You need a lot of raw material of the right quality to make investing in the recycling technology and the recycling system worthwhile," he said.<span></span><br></p>
Hemp, Sugar Cane and Sustainable Alternatives<p>Some projects are instead addressing the material used to make masks.</p><p>French company Geochanvre have created a mask made primarily from hemp, while in Australia, researchers at the Queensland University of Technology are experimenting with a disposable product made from agricultural waste. </p><p>Biodegradable options are exciting alternatives to reduce the fossil fuels needed for the creation of plastic-based masks, said Krones, but they don't absolve the wearer from the responsibility of what happens afterwards. </p><p>Bio-based masks often need their own composing solutions, he explains, because in landfill they can produce high amounts of the greenhouse gas methane when anaerobic bacteria feeds on the organic material. Methane is known to be significantly more potent than carbon dioxide.</p><p>"I think as long as we have in our mind that we want to have disposability, we're going to have to wrestle with a variety of different sorts of environmental tradeoffs," he said, adding that reusable, fabric masks are the best option available to most people.</p><p>Precimask is developing a clear face covering with an optional visor made from hard plastic, designed to be long-lasting.<br></p><p>Air enters either side of the cheeks through a technology normally found in pool filters and car exhaust systems, said company spokeswoman Juliette Chambet.</p><p>"We wanted to make ceramic-based filters that would be washable and cleanable, which would allow them to be reused as many times as desired without having to buy a new consumable or produce waste," she said. </p><p>Ultimately, encouraging mask wearers to think about the entire lifecycle of a mask is key, explains Neveu. </p><p>"We want people who put on the masks to realize that they are also responsible for the waste, he said. "It's not inevitable that this [pandemic] will become an environmental catastrophe.</p><p><em>Reposted with permission from </em><em><a href="https://www.dw.com/en/covid-19-recycling-pollution-trash-pandemic/a-55707817" target="_blank">Deutsche Welle</a>.</em><a href="https://www.ecowatch.com/r/entryeditor/2649032193#/" target="_self"></a></p>
