In 2003, 2007 and 2013, Sudan was particularly harshly affected by flash floods that displaced hundreds of thousands of people. In order to better prepare and warn farmers of flood events, they need access to real-time information and they need to be able to exchange and apply the information.
The White House is currently working with NASA, the National Oceanic and Atmospheric Administration (NOAA) and different technology companies to create a website and database with information on how climate change affects public health and infrastructure in the United States.
A team of geographers at University of California have developed a new approach to measure river flows from outer space. This approach relies exclusively on the measurements of a river's width over time, which can be obtained from freely available satellite imagery. "Our new method doesn't require access to the country or getting in the river to safely take measurements in the field," said Colin Gleason, lead author of the study and a doctoral student in geography in UCLA.
