Chornobyl Dome Struck by Drone
A drone carrying a high-explosive warhead struck the dome protecting the damaged reactor 4 at Ukraine’s Chornobyl Nuclear Power Plant. Chornobyl (also known as Chernobyl as transliterated from Russian), was the site of the world’s worst nuclear accident in 1986, leading to the spread of deadly radiation across large areas of Ukraine and neighboring Belarus, in addition to lesser amounts of radiation distributed much further away. In 2016, a structure called the New Safe Containment (NSC) was put in place to isolate the reactor that melted down. The drone that struck the NSC was tracked as coming from the direction of the Russian/Belarusian border, leading Ukraine to pin blame for the blast on the Russian military’s ongoing campaign against Ukraine. Russian authorities have denied responsibility. The International Atomic Energy Agency reports no uptick in radiation from the site, despite damage to the NSC’s outer dome.

LA County Flooding Fallout
Southern California experienced the most intense rainfall it has had in over a year yesterday, leading to floodwater covering roads and trapping cars. During the storm, a “weak tornado” ripped roofs off of mobile homes and tore down power lines. Evacuations were ordered, particularly near areas impacted by the devastating wildfires earlier this year. Severe mudslides carried heavy debris, posing a significant safety risk to residents. While impacts were devastating, much of the harm anticipated in flash flood warnings was averted, since most of the zones impacted by the wildfires were spared.

AI to Protect Mid-Atlantic Whales
Researchers at Rutgers University-New Brunswick have developed an artificial intelligence (AI) tool that will help predict endangered whale movements, guiding ships along the Atlantic coast to avoid them. The tool is designed to prevent deadly accidents as well as inform conservation strategies and responsible ocean development. The machine-learning program employed by the researchers analyzed two vast data sets to discover patterns and relationships in how whales moved between different areas, and as it encountered more data, it adjusted its internal model to make better predictions or classifications. The information analyzed by the computer model includes underwater glider and satellite-based data dating back to 1992. This AI method improves upon present abilities to monitor the ocean for the distribution of important marine species, such as the critically endangered North Atlantic right whale.

 Artificial Intelligence (AI) has only just begun to open new pathways of exploration in the world of geospatial technology. The promise of computer-aided monitoring and analysis offers potential rewards still hidden beyond the horizon. Join the American Geographical Society this November at Columbia University in New York City to imagine all the possibilities at Geography 2050: The Future of GeoAI and the Planet. |

Q: According to archaeological evidence, how many places have been discovered across the globe where agriculture originated independently?
A: Nine
Nikolai Vavilov, a Russian agricultural scientist, proposed eight geographic centers as the birthplaces or “centers of origin” of crops—the places where the ancestors, wild relatives, and other related species of crops still live and where mankind first began their cultivation. These eight centers include China, India and the Indo-Malayan region, Central Asia (including Pakistan, Afghanistan, Turkmenistan, and the northwest Indian provinces of Punjab and Kashmir), the Fertile Crescent (Turkey, Levant, Iran, Iraq), the Mediterranean, Ethiopia, southern Mexico and Central America, and South America (Ecuador, Peru, Bolivia, Chile, and Brazil-Paraguay). A ninth center of diversity, New Guinea, was discovered after his death. Overall, Vavilov associated about 640 crops with their biodiversity centers. Five-sixths of these came from the Old World (Asia, Africa, Europe) and one-sixth from the New World (Australia, North and South America).
