• Cost-Effective Ways to Reduce Risks in the Supply Chain

    The coronavirus pandemic has hit the economy hard. What lessons can be learned from this experience? And what’s the best way for companies to protect themselves against this kind of crisis in the future? The answer will certainly involve a combination of different approaches – but new mathematical methods look likely to be a very promising piece of the puzzle.

  • Venice Ambitious Anti-Flood System Passes First Trial

    Venice On Friday conducted the first test of a controversial dam system made up of 78 inflatable barriers, aiming to protect the city from severe flooding. The ambitious and costly dam system, launched in 2003, has been plagued by corruption and is nearly a decade behind schedule. It will becoe fully operational by the end of 20201, and it is designed to hold water surges as high as 10 feet.

  • Securing the Smart Home

    So…you’ve built your smart home, it’s got smart heating and lighting, all the latest smart communications and entertainment systems, and of course, smart power generation to make it smart and green. But, how do you keep it secure and stop forced digital or physical entry? Well, you need smart security too, of course.

  • Why Japanese Businesses Are So Good at Surviving Crises

    On 11 March 2011, a 9.1-magnitude earthquake triggered a powerful tsunami, launching 125-feet high waves at the coast of the Tohoku region of Honshu, the largest and most populous island in Japan. nearly 16,000 people were killed, hundreds of thousands displaced, and millions left without electricity and water. Railways and roads were destroyed, and 383,000 buildings damaged, including a nuclear power plant at Fukushima. “In lessons for today’s businesses deeply hit by pandemic and seismic culture shifts, it’s important to recognize that many of the Japanese companies in the Tohoku region continue to operate today, despite facing serious financial setbacks from the disaster,” she writes. “How did these businesses manage not only to survive, but thrive?”

  • Lessening Water Quality Problems Caused by Hurricane-Related Flooding

    June 1 is the start of hurricane season in the Atlantic, and with 2020 predicted to be particularly active, residents in coastal regions are keeping watchful eyes on the weather. Flooding is often the most damaging effect of tropical storms, and one of the first casualties of large-scale is the quality of water sources in the flooded areas.

  • Vital Natural buffers against Climate Change Are Just Offshore

    About 31 million people worldwide live in coastal regions that are “highly vulnerable” to future tropical storms and sea-level rise driven by climate change. But in some of those regions, powerful defenses are located just offshore. Of those 31 million people, about 8.5 million directly benefit from the severe weather-protection of mangroves and coral reefs, key buffers that could help cushion the blow against future tropical storms and rising waters.

  • Mangrove Trees May Disappear by 2050 Due to Sea-Level Rise

    Mangrove forests store large amounts of carbon and  help protect coastlines, but mangrove trees – valuable coastal ecosystems found in Florida and other warm climates – won’t survive sea-level rise by 2050 if greenhouse gas emissions aren’t reduced.

  • Cybercriminals Are Now Targeting Critical Electricity Infrastructure

    By Henri van Soest

    Amid the constant stream of news on the coronavirus pandemic, one event passed relatively unnoticed. On the afternoon of May 14, a company named Elexon was hacked. You probably haven’t heard of it, but Elexon plays a key role in the UK’s electricity market, and though the attack did not affect the electricity supply itself, as an academic who researches cybersecurity in the electricity system, I am worried. This near miss reveals just how vulnerable our critical infrastructure is to such attacks – especially during a pandemic.

  • Do Two Failed Dams Foretell a Dire Future?

    By Upmanu Lall and Paulina Concha Larrauri

    Climate change is increasing the frequency of extreme rainfall events and hence the risk for filling and overtopping dams, which is the predominant mechanism of dam failure. However, using climate change as a bogeyman for aging infrastructure failure is an unfortunate trend, since it takes attention away from an urgent and potentially fixable problem.

  • When Dams Cause More Problems Than They Solve, Removing Them Can Pay Off for People and Nature

    By Jon Honea

    Across the United States, dams generate hydroelectric power, store water for drinking and irrigation, control flooding and create recreational opportunities such as slack-water boating and waterskiing. But dams can also threaten public safety, especially if they are old or poorly maintained.

  • The USGS Prepares to Respond During the 2020 Atlantic Hurricane Season

    The 2020 Atlantic hurricane season starts1 June, and the U.S. Geological Survey says it is prepared to provide science that can help guide efforts to protect lives and property if a major storm makes landfall this season. USGS brings many capabilities to help communities deal with hurricanes: the ability to forecast coastal change; track storm surge, river and stream levels and flow; capture high-resolution ground elevation and topographic data; create detailed maps that can be used by disaster teams responding in the aftermath of storms; and measure coastal and inland flooding across entire regions.

  • Rising Tide: Seeking Solutions to S.C.’s Mounting Nuisance Floods

    While a rising tide may lift all boats, it spells trouble for South Carolina coastal communities where flooding has already long been a fact of life. Low-lying areas such as the state’s more than 2,000 miles of coastline are increasingly prone to floods and storm surge as sea levels rise — driven by a more variable global climate system. Researchers are examining green solutions to help those communities fight back.

  • Bans on Foreign Equipment in U.S. Critical Infrastructure

    One executive order does not a trend make, but maybe two do. On May 1, President Trump issued an executive order banning the acquisition, importation, transfer or installation of any bulk electric power system equipment where the secretary of energy has determined, first, that the equipment was manufactured by a company controlled by—or subject to the jurisdiction of—a foreign adversary and, second, that the transaction poses an undue risk to the U.S. bulk-power system, economy or national security. Jim Dempsey writes “The order’s issuance signals that the administration’s efforts to purge from the nation’s telecommunications network any equipment made in China may represent a new approach to critical infrastructure in general.”

  • Harnessing Wave Power to Rebuild Islands

    By David L. Chandler

    Many island nations, including the Maldives in the Indian Ocean, are facing an existential threat as a result of a rising sea level induced by global climate change. Researchers are testing ways of harnessing nature’s own forces to help maintain and rebuild threatened islands and coastlines.

  • As Sea Levels Rise, Are We Ready to Live Behind Giant Walls?

    By Hannah Cloke

    Of all the many varied impacts in a warming planet, sea level rise is one of the most straightforward to predict because sea water expands as it warms and because extra water is flowing from melting glaciers and ice sheets. Given the costs of flooded coastal cities, European Commission scientists suggest that it would save money in the long run to build improved sea defenses around 70% of the continent’s coastline. Do we really want to live in a world in which we all live behind huge walls? Is this the only way to adapt?
