UNITED NATIONS (Sputnik) – Economic losses from natural disasters have now reached $300 billion annually, and are projected to increase dramatically, according to the UN chief.
"By 2050, we estimate that up to one billion people could be displaced by climate change," Ban said adding that more than 40 percent of the global population would be living in areas of severe water stress.
Ban added that natural disasters are happening more often and inflict more damage, while leaving behind a more lasting negative impact.
The secretary general said humanitarian action faces great challenges despite the UN's and other organizations' efforts, as the number of people in need of humanitarian assistance has doubled globally over the past decade.
Ban named urbanization, population growth, environmental degradation, conflict, climate change and resource scarcity as the main factors contributing to the worsening humanitarian situation.
