Park-Like Tsunami Defenses: Sustainable Alternative to Towering Seawalls
In tsunami preparedness, it turns out there can be strength in beauty. Rows of green hills strategically arranged along coastlines can help to fend off destruction from tsunamis while preserving ocean views and access to the shore. For some communities, they may offer a better option than towering seawalls.

Sea Level Could Rise More than 1 Meter by 2100 if Emission Targets Are Not Met
Global mean sea-level rise could exceed 1 meter by 2100 and 5 meters by 2300 with unchecked emissions, a survey among 100 leading international experts finds. The risk assessment is based on the increasing body of knowledge of the systems involved – while the scientists highlight the remaining uncertainties, they say it is clear now that previous sea-level rise estimates have been too low.

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.

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.

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.

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.

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.

Cybersecurity Requires International Cooperation, Trust
Most experts agree that state-sponsored hackers in Russia are trying to use the internet to infiltrate the U.S. electrical grid and sabotage elections. And yet internet security teams in the U.S. and Europe actively seek to cooperate with their Russian counterparts, setting aside some of their differences and focusing on the issues where they can establish mutual trust.

Coronavirus: People in Tall Buildings May Be More at Risk – Here’s How to Stay Safe
The COVID-19 pandemic has challenged health systems and public health authorities worldwide. When you have a rapidly spreading virus with a high transmission rate, you have to investigate all possible infection risks.
Michael Gormley writes in The Conversation that one area of risk that is yet to receive any attention is big buildings such as tower blocks or hospitals. While direct person-to-person transmission is still the most common means of acquiring the illness, our research suggests that occupants in tall buildings could become infected if defects occur in the plumbing system. It’s important for people to be aware of this and take steps to keep themselves safe.
His group’s work at the Institute for Sustainable Building Design at Heriot-Watt University stems from an outbreak of the SARS virus in 2003 at an apartment block in Hong Kong, known as Amoy Gardens. In a building complex ranging from 33 to 41 storeys with some 19,000 residents, there were more than 300 confirmed cases and 42 deaths – around one-sixth of all SARS infections and fatalities on the island as a whole. -

COVID-19 and the Built Environment
Social distancing has Americans mostly out of the places they usually gather and in their homes as we try to reduce the spread of COVID-19. But some buildings, such as hospitals and grocery stores, have to remain open, and at some point, most of us will go back to the office or workplace. What is the role of building design in disease transmission, and can we change how we design the built environment to make it healthier? Modern buildings are generally designed to promote social mixing — from open plan living areas in homes to open offices where many workers share space. By promoting interaction and chance encounters, these layouts are thought to generate more creativity and teamwork. At the same time, they are probably also really great for spreading viruses around.
