  Conventional approaches to cosmology in supergravity assume the existence of
multiple sectors that only communicate gravitationally. In principle these
sectors decouple in the limit Planck mass to infinity. In practice such a limit
is delicate: for generic supergravities, where sectors are combined by adding
their Kahler functions, the separate superpotentials must contain non-vanishing
vacuum expectation values supplementing the naive global superpotential. We
show that this requires non-canonical scaling in the naive supergravity
superpotential couplings to recover independent sectors of globally
supersymmetric field theory in the decoupling limit Planck Mass to infinity.
