A quick google search - Helen Keller introduced it in Nepal in 2007, also coined as Helen's potato. May be good place to start.

Suaahara, which was a consortium between Save the Children, HKI, John Hopkins (+ more partners) were encouraging the growth of orange sweet potatoes in their programmes. That is the only information I have though, so maybe someone who worked specifically on this could provide more information?
