In this talk I discuss modern scenarios of string theory compactification.
The goal is to derive lower-dimensional supergravity coupled to
non-abelian gauge fields and matter fields with interactions provided by
fluxes on the internal space.
It is expected that the supergravity could be formulated as the
consistent low-energy effective theory which involves string dualities,
by virtue of new techniques such as generalized geometries, doubled
spaces, and embedding tensors.
