  We construct supergravity models allowing to sequester the phenomenology of
inflation from the Planckian energy scale physics. The procedure consists of
two steps: At Step I we study supergravity models, which might be associated
with string theory or M-theory, and have supersymmetric Minkowski vacua with
flat directions. At Step II we uplift these flat directions to inflationary
plateau potentials. We find certain conditions which ensure that the superheavy
fields involved in the stabilization of the Minkowski vacua at Step I are
completely decoupled from the inflationary phenomenology.
