  • Protecting tropical forest carbon stocks may not prevent large-scale species loss
    on July 16, 2018 at 8:45 pm

    As the world seeks to curb human-induced climate change, will protecting the carbon of tropical forests also ensure the survival of their species? A study suggests the answer to this question is far from straightforward. Forests with the greatest carbon content do not necessarily house the most species, meaning carbon-focused conservation can miss large swathes of tropical forest biodiversity. […]

  • From property damage to lost production: How natural disasters impact economics
    on April 11, 2018 at 9:41 pm

    When a natural disaster strikes, major disaster databases tend to compile information about losses such as damages to property or cost of repairs, but other economic impacts after the disaster are often overlooked -- such as how a company's lost ability to produce products may affect the entire supply-chain within the affected region and in other regions. This may give an incomplete picture of the full financial impact of the disaster. […]
