humanitarian aid

I’m studying for my Sociology class and need an explanation.

The Rysaback-Smith article and the Sphere Guidelines discuss some history of humanitarian aid and the basic principles that govern humanitarian aid.  Do you see the manner in which humanitarian aid is provided changing?  Please describe the change and how it could impact populations requiring aid as well as the impact on providers of humanitarian aid.
