M-theory, accessed via eleven-dimensional supergravity, admits solutions with eight-dimensional compact internal spaces, exhibiting fluxes and warping. These solutions require higher derivative terms in the 11d action and field equations to be properly handled, for global consistency. We will examine the induced corrections to the 11d vacua and then derive the effective theories corresponding to the reduction on these spaces. This will allow us to analyze the corrections to mass terms and kinetic terms in the 3d effective theories.
