Intense drought in South Africa’s Western Cape Province has led the world-renowned city of Cape Town to the brink of “Day Zero”—the date at which residents would be forced to collect strictly rationed water supplies from shared distribution taps. Water conservation efforts have so far prevented a massive water shutdown, but the city’s rapid population growth and reliance on surface water dams makes it particularly vulnerable to lower precipitation levels. 

Cape Town is running dry. But thanks to its sophisticated water management efforts, the city may ride out the crisis. However, other cities that lack these capacities are less likely to survive Day Zero. Especially in developing countries, where urban water services are often provided by informal or illegal actors, running out of water could have dangerous ripple effects for peace and security.

Russia is “playing politics with energy supplies,” said U.S. Secretary of State Rex Tillerson at a major policy speech at the Wilson Center this week. He accused Russia of wielding natural gas “as a political weapon” and said that ensuring European energy security was “fundamental” to U.S. national security objectives. In Europe, the debate is raging over how best to achieve energy security in the face of the twin challenges of Russian dominance and the need to decarbonize the economy. The ongoing securitization of Russian natural gas could not only complicate the road to a low carbon future in Europe, it could also undermine a European integration project that has mostly been a success.

“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.

$1 billion sales in two minutes. More than 250,000 purchases every second. Singles’ Day, China’s annual retailing extravaganza, absolutely crushes Black Friday: E-commerce giant Alibaba raked in $17.8 billion in gross sales during last year’s event, more than double the combined total of $6.8 billion in sales during the United States’ 2016 holiday shopping kick-off. The shopping spree lasts only 24 hours, but its environmental impacts will extend for decades.

Launched in Beijing in 2013, the highly successful grassroots “Empty Your Plate” campaign encourages Chinese consumers to eliminate food waste from their meals. Starting with blog posts on Weibo (China’s equivalent of Twitter), this campaign rapidly swept the entire country and attracted support from the central government, which later issued a series of policies urging restaurants to use smaller dishes and remove minimum charges. However, the volume of food waste in China is still astonishing.

HONOLULU – Sludge. The final, unwanted byproduct of a toilet flush. The semi-solid stuff that even wastewater treatment plants send packing to the landfill. Unseen in the steel pipes snaking high on the exterior of Honolulu’s H-POWER plant, sludge is injected into a massive boiler where it joins the city’s trash in a roaring inferno. From the gravel lot outside, it all seems very antiseptic and smells less than a stroll past the neighborhood dumpster. But the 70-megawatt waste-to-energy facility is a workhorse, processing as much as 2,000 tons of refuse each day from Oahu’s 1 million residents. All told, it generates up to 10 percent of the electricity needed to power this Pacific island.
