Cities Will Endure, but Urban Design Must Adapt to Coronavirus Risks and Fears
The long-term impacts of coronavirus on our cities are difficult to predict, but one thing is certain: cities won’t die. Diseases have been hugely influential in shaping our cities, history shows. Cities represent continuity regardless of crises – they endure, adapt and grow. Silvia Tavares and Nicholas Stevens write in The Conversation that urban designers and planners have a long-term role in ensuring urban life is healthy. To fight infectious diseases, cities need well-ventilated urban spaces with good access to sunlight. The design of these spaces, and public open spaces in particular, promotes different levels of sociability. Some spaces congregate community and are highly social. Others may act as urban retreats where people seek peace with their coffee and book. How urban spaces perform during disease outbreaks now also demands our close attention.

An Atomic Catch 22: Climate Change and the Decline of America's Nuclear Fleet
Nuclear energy in the United States has become deeply unprofitable in the last decade, driven by a combination of aging infrastructure and other electricity sources like renewables and natural gas simply becoming cheaper to build and operate. While some in the environmental community may cheer nuclear’s decline, others are concerned. Love it or hate it, nuclear plays a unique role in the American electric sector, one for which we currently have no market-ready replacement, and its decline will likely make other environmental issues, particularly climate change, harder to solve.

Changes in Snowmelt Threaten Farmers in Western U.S.
Farmers in parts of the western United States who rely on snowmelt to help irrigate their crops will be among the hardest hit in the world by climate change, a new study reveals. The study pinpointed basins globally most at risk of not having enough water available at the right times for irrigation because of changes in snowmelt patterns. Two of those high-risk areas are the San Joaquin and Colorado river basins in the western United States.

Waterfront Development Added Billions to Property Values Exposed to Hurricane Florence
Rapid development in flood-prone zones during recent decades helped boost the amount of property exposed to 2018’s devastating Hurricane Florence substantially, a new study says. It estimates that the value of property in North Carolina and South Carolina potentially exposed to flooding at $52 billion—$42 billion more than at the start of the century (in 2018 dollars). While much development took place between 1950 and 2000, financial risk rose quickly afterward because much of it clustered along coastlines and adjacent to rivers and lakes, where buildings were more vulnerable to flooding.

Irrigation Expansion Could Feed 800 Million More People
Agriculture, which accounts for 90 percent of global water use, is the largest driver of water scarcity worldwide, and it is often the most vulnerable and disadvantaged populations that suffer the severest consequences. A new study suggests that there is enough locally available water to expand irrigation over 140 million hectares of agricultural lands.

Consequences Remain Decades After Chernobyl Disaster: UN
The United Nations says persistent and serious long-term consequences remain more than thirty years after the explosion and fire at the Chernobyl nuclear power plant in Ukraine. The world body is marking International Chernobyl Disaster Remembrance Day on 26 April, the 34th anniversary of the accident that spread a radioactive cloud over large parts of Belarus, Ukraine, and Russia. The anniversary is being marked after fires recently burned in the 30-kilometer exclusion zone around the plant, raising concerns about the potential release of radioactive particles into the air.

U.K.: Parliamentary Opposition to Huawei’s 5G Deal Growing Significantly
Support in the British Parliament for allowing Huawei a role in Britain’s 5G network is collapsing. In January, the U.K. government granted Huawei approval to supply 5G technologies for parts of the U.K. network – with some restrictions, which critics of the deal say are meaningless. The government’s plan requires an act of Parliament to take legal effect, but the opposition to the deal among members of Prime Minister Boris Johnson’s Conservative Party has been steadily growing, especially in light of China’s lack of transparency regarding the coronavirus epidemic. Observers now say that the hardening of opposition to the deal among rank-and-file Conservative MPs will make it difficult — if not impossible — to get the legislation passed.

New Flood Damage Framework to Help Planners Prepare for Sea-Level Rise
Scientists agree that sea levels will continue to rise this century, but projections beyond 2050 are much more uncertain regarding exactly how much higher ocean levels will be by 2100. While actions to protect against 2050 sea-level rise have a secure scientific basis, this range in late-century estimates makes it difficult for coastal communities to plan their long-term adaptation strategies.

Deepwater Horizon Oil Spill 10 Years On: What Did Scientists Learn?
Ten years ago, a powerful explosion destroyed an oil rig in the Gulf of Mexico, killing 11 workers and injuring 17 others. Over a span of 87 days, the Deepwater Horizon well released an estimated 168 million gallons of oil and 45 million gallons of natural gas into the ocean, making it the largest accidental marine spill in history.

Improving Accuracy of Storm Surge Analysis
Accurately predicting how many people are at risk due to sea level rise and storm surges has always challenged scientists, but a new method is improving models that account for the impact of these natural occurrences. A new model developed by international team of scientists can be used to better understand and prepare for the impacts of climate change.

Maintaining Nuclear Safety and Security During the COVID-19 Crisis
Every major industry on earth is struggling to adapt in the face of the COVID-19 pandemic. This includes nuclear facilities and nuclear-powered vessels, which count among the critical infrastructure of dozens of nations now struggling with the pandemic, representing more than half the world’s population. Meanwhile, ISIS has already announced its intent to exploit the pandemic while a number of other violent extremist organizations are also taking pains to exploit the crisis. Without implementing extraordinary measures to maintain safety and security, nuclear installations risk compounding the crisis with a large-scale radiation release.

What to Make of New U.S. Actions Against Foreign Telecoms
Recent moves by the administration mark another concrete step in the U.S. campaign to limit the digital and economic influence of Chinese telecommunications companies both within and outside U.S. borders. Justin Sherman writes that “The moves also demonstrate that current American efforts to limit the influence of the Chinese telecommunications sector are much broader than just the well-publicized targeting of Chinese telecom giant Huawei.”

Extreme Coastal Flooding in the U.S. Expected to Rise
Extreme flooding events in some U.S. coastal areas could double every five years if sea levels continue to rise as expected, a new study says. Today’s “once-in-a-lifetime” extreme water levels — which are currently reached once every fifty years — may be exceeded daily along most of the U.S. coastline. Associated coastal hazards, such as beach and cliff erosion, will likely accelerate in concert with the increased risk of flooding, suggest the authors.

Bolstering Cybersecurity for Systems Linking Solar Power to Grid
DOE has awarded researchers $3.6 million to advance technologies that integrate solar power systems to the national power grid. “As U.S. energy policy shifts toward more diverse sources, particularly solar, the Energy Department understands the critical importance of protecting these systems and technologies,” said Alan Mantooth, U Arkansas Professor of electrical engineering and principal investigator for the project.

Understanding the Hidden Impact of Disasters
The September 2017 Hurricane Maria killed people, demolished homes, and destroyed infrastructure. But Maria also damaged the manufacturing plants of a major IV bag maker, plunging hospitals into supply shortage that didn’t ripple across the mainland United States until six months after the hurricane made landfall. Given the highly integrated nature of supply chains in the U.S., natural and man-made disasters can have unanticipated consequences that are every bit as serious as the immediate damage of the event itself.
