DESCRIPTION:In ten- and four-dimensional supergravities\, the descriptions
  of non-geometric configurations are different. In the former\, non-geomet
 ry arises as naively non-single valued supergravity fields. In the latter\
 , new terms\, coming from non-geometric Q- and R-fluxes\, appear in the fo
 ur-dimensional potential. In this talk\, it is shown that a ten-dimensiona
 l field redefinition results in a Q-flux term in the NSNS Lagrangian. This
  change of field basis is inspired by generalized geometry. We argue that 
 this new field basis provides a good description of certain non-geometric 
 configurations. In particular\, using the new basis\, a dimensional reduct
 ion can be performed\, in which the Q-flux term gives rise to the expected
  term in the four-dimensional potential. We also discuss the global issues
  of this set-up.\n
