International aid projects come under the microscope

Published on by

I just came across this new,http://www.nature.com/news/international-aid-projects-come-under-the-microscope-1.12268

And trust me, I just loved it. Water and sanitation is gathering so much of attention and huge aid is coming to development countries for this. Iw onder where these grants goes? Does it make any changes? What other members think about this?
