  The influence of nuclear multiscattering and shadowing on pion spectra is
investigated in $pA$ collisions from CERN SPS to RHIC energies. The
calculations are performed in a next-to-leading order (NLO) pQCD-improved
parton model, including intrinsic partonic transverse momentum distributions.
The nuclear modification of the pion spectra (Cronin effect) is considered at
different targets in a wide energy range. Theoretical predictions are displayed
for planned $pA$ experiments at CERN SPS and recent $dAu$ experimental results
are analysed at RHIC.
