Cassava is a staple food for millions of people across the developing world. What is this disease I read about in the New York Times that is spreading from East Africa to as far as Nigeria and Angola, and is decimating this essential food crop?
Strange that the NYTimes doesn't name the disease. But I found other articles that identify the disease as a new and particularly virulent strain of "cassava brown streak disease." FAO reported on the danger of the outbreak in November of 2011. Visit this article from the FAO newsroom to access a video of FAO Agricultural Officer Jan Helson, as he speaks about the disease.
