  The backreaction on the Randall-Sundrum warped spacetime is determined in
presence of scalar field in the bulk. A general analysis shows that the
stability of such a model can be achieved only if the scalar field action has
non-canonical higher derivative terms. It is further shown that the gauge
hierarchy problem can be resolved in such a stabilized scenario by appropriate
choice of various parameters of the theory. The effective cosmological constant
on the brane is shown to vanish.
