The unprecedented cost of the 2018 Kilauea eruption in Hawai'i reflects the intersection of distinct physical and social phenomena: infrequent, highly destructive eruptions, and atypically high population growth, according to a new study led by University of Hawai'i at Mānoa researchers.
The University of Toronto Engineering research team used city and survey data to map Toronto's entire cycling network - including the new routes - and found that additional bike infrastructure increased low-stress road access to jobs and food stores by between 10 and 20 per cent, while boosting access to parks by an average of 6.3 per cent.
Insurance policy premiums from the National Flood Insurance Program (NFIP) allow policyholders to maintain a lower, grandfathered rate even when the risk escalates. But as coastal flooding increases due to rising sea level and more intense storms, new research published in the journal Risk Analysis suggests this grandfathered policy could lead to big losses for the NFIP.
Sharing the press release that I hope you will find interesting: A research team from Skoltech (Russia) and FBK (Italy) presented a method to derive 4D building models using historical maps and machine learning (ML). It is useful for understanding urban phenomena and changes that contributed to defining our cities' actual shapes.
Experts analysing crime and car accident data in Mexico City found a surprisingly high level of synchronicity between the two on a weekly cycle, suggesting that applying more resources to prevent road accidents would improve crime rates by enabling more efficient policing.
In the inaugural issue of npj Urban Sustainability, a new Nature Partner Journal out today, a team of leading urban ecologists outlines a practical checklist to guide interventions, strategies, and research that better position urban systems to meet urgent sustainability goals.
Smart agriculture is set to revolutionize food production in the next few decades. However, the integration of information technology in agricultural processes also brings security and privacy concerns. In a new survey published in IEEE/CAA Journal of Automatica Sinica, scientists discuss these challenges and propose countermeasures applicable to different areas of agricultural production. They also provide guidance for future research, suggesting key areas of focus in the ever-growing field of smart agriculture.
Increases in air pollution and greenhouse gas emissions caused by ridesourcing impact human health and the environment--what happens when companies shoulder that cost?
Unmanned aerial vehicles (drones), autonomous cars, robots that can repair urban infrastructure and wireless sensor networks used for monitoring, etc. are just some of the devices that will spring up all over our cities in a few years. They have a wide range of potential applications, such as autonomous transport, waste collection, infrastructure maintenance and repair, surveillance and precision agriculture, among others. However, we must also consider the impact these technologies will have on urban biodiversity and its ecosystems in the future.
Semi-trucks and other heavy-duty vehicles are responsible for nearly half of road transportation carbon dioxide emissions in Europe, according to the International Council on Clean Transportation. A team of researchers in Italy has proposed a plan to reduce the emissions without compromising priorities such as delivery times. They published their approach in IEEE/CAA Journal of Automatica Sinica, a joint publication of the IEEE and the Chinese Association of Automation.
