Not Too Big—Not Too Small—Just Right: Sand Bioreactor Wastewater Treatment in Chinese Villages
›One year after the Sichuan earthquake, while visiting villages near Wenchuan, I asked local officials planning reconstruction about their plans for wastewater treatment. As an agricultural engineering professor, I was not surprised to learn that they had no plans. It was not that a wastewater treatment system was too expensive, they worried that it would be too big.

Better Water Security Translates into Better Food Security
›“Food production is the largest consumer of water and also represents the largest unknown factor of future water use as the world’s population continues to balloon, and we face increasing weather-related shocks and stresses,” said Laura Schulz, Acting Deputy Assistant Administrator in USAID’s Bureau for Economic Growth, Education and Environment. She spoke at “Feeding a Thirsty World: Harnessing the Connections Between Food and Water Security,” an event sponsored by the Wilson Center, Winrock International, the Sustainable Water Partnership, and USAID. Currently about 70 percent of global water goes to agriculture, a number that is projected to rise “as high as 92 percent,” said Rodney Ferguson, the President and CEO of Winrock International.

Tapping the Power in China’s Municipal Sludge
›In September 2018, the Jinghu District People’s Court in Wuhu, Anhui Province sentenced 12 people from the Pol Shin Fastener Company between four months and six years in prison for committing serious interprovincial environmental crimes in Jiangsu and Anhui in 2016 and 2017. The court also fined the automobile hardware manufacturer 10 million yuan ($1.48 million). The crime? Dispatching ships and trucks to illegally dump 2500+ metric tons of highly acidic pickling sludge from steel production. Sludge—semi-solid waste emissions from industries and municipal water treatment plants—is yet another tough water and solid waste pollution challenge China faces.

Groundwater Scarcity, Pollution Set India on Perilous Course
›Doula Village lies 55 kilometers (34 miles) northeast of New Delhi on a flat expanse of Uttar Pradesh farmland close to the Hindon River. Until the 1980s Doula Village’s residents, then numbering 7,000, and its farmers and grain merchants, thrived on land that yielded ample harvests of rice, millet, and mung beans. The bounty was irrigated with clean water transported directly from the river, or with the sweet groundwater drawn from shallow wells 7 meters (23 feet) deep.

China’s Waste Import Ban: Dumpster Fire or Opportunity for Change?
›In early January of this year, China’s “National Sword” policy banned imports of non-industrial plastic waste. The ban forces exporting countries to find new dumping grounds for their waste, which is estimated to total nearly 111 million metric tons by 2030. China’s decision has exposed deep structural flaws and interdependencies in the global waste management system. Western countries that have long depended on China to take their garbage are now struggling to deal with mounds of plastic trash, while China lacks the low-priced labor needed to effectively sort and process waste.

Every Day is Earth Day: Plastic Waste Q&A with Mao Da
›Plastics. From the devastating effects of plastic pollution on our oceans, to the news that plastic bottles likely pollute the drinking water they contain, plastic pollution—the theme of this year’s Earth Day—has been a highly visible issue, and we’ve seen some notable progress on fighting the plastic battle.

Managing Sludge Mountains: What Beijing Can Learn From Brazil
›Just days before the 2016 Summer Olympics began in Rio de Janeiro, the Brazilian city faced an unsavory problem: how to handle its overwhelming sewage. Nearly half of Rio’s municipal wastewater flowed untreated into Guanabara Bay, where the waters were so polluted by sludge that direct contact was deemed a health hazard to Olympic athletes.

The “Most Important Issue We Face”: New U.S. Global Strategy for Water Emphasizes Health and Security
›“Water may be the most important issue we face for the next generation,” writes President Donald J. Trump on the first page of the first-ever U.S. Global Water Strategy. Prepared by the U.S. State Department and released in mid-November, the landmark report was required by Congress’ bipartisan Senator Paul Simon Water for the World Act of 2014. During the public comments phase, the New Security Beat published recommendations from its fellows and experts. Now that it is out, we’ve asked them to share their thoughts on the final report.
