FEMA Maps Said They Weren’t in a Flood Zone. Then Came the Rain.
The most common reference for flood risk are the flood insurance rate maps, also known as 100-year floodplain maps, that the Federal Emergency Management Agency, or FEMA, produces. They designate so-called special flood hazard areas that have a roughly 1 percent chance of inundation in any given year. Properties within those zones are subject to more stringent building codes and regulations that, among other things, require anyone with a government-backed mortgage to carry flood insurance. Flaws in federal flood maps leave millions unprepared. Some are trying to fix that.

Beaver-Like Dams Can Enhance Existing Flood Management Strategies for At-risk Communities
River barriers made up of natural materials like trees, branches, logs and leaves can reduce flooding in at-risk communities. Leaky barriers are effective in slowing down the flow of the river during periods of rainfall and storing up vast quantities of water which would otherwise rush through causing damage to communities downstream.

Reached: Milestone in Power Grid Optimization on World’s First Exascale Supercomputer
Ensuring the nation’s electrical power grid can function with limited disruptions in the event of a natural disaster, catastrophic weather or a manmade attack is a key national security challenge. Compounding the challenge of grid management is the increasing amount of renewable energy sources such as solar and wind that are continually added to the grid, and the fact that solar panels and other means of distributed power generation are hidden to grid operators.

Senate Fails to Reauthorize Chemical Facility Security Program
Chemical industry groups are warning that thousands of chemical facilities across the United States could face increased risk of terrorist attacks after the Senate last week adjourned for its summer recess without approving pending House legislation reauthorizing the Chemical Facility Anti-Terrorism (CFATS) program.

“Hacking” People, Not Systems: False Claims Attacks on Infrastructure
False claims and disinformation, especially in a social media-driven society, have become major problems with potentially severe consequences. Disinformation can be weaponized to disrupt underlying cyber-physical systems, human lives and economic productivity. Recent examples include tweets that trigger spikes in gasoline prices and false social media posts reporting impending water pumping station shutdowns. In these scenarios, chaos is caused because people, not systems or devices, are “hacked.”

A Turning Point: U.S. Recognizes Agriculture as a Domain of Defense
The US has legitimized the role of food supply in national defense. It has recognized that in a world of rupture, a nation that cannot feed itself cannot defend itself. A new policy effectively ends the era of agriculture functioning solely as a commercial sector.
