  Hadron production at forward rapidities in d+Au collisions is studied in the
framework of parton recombination in the final state. Multiple scattering and
gluon saturation in the initial state are not explicitly considered. The
recombination of soft and shower partons is found to be important. The soft
parton densities are determined by extrapolation from the parametrization fixed
at \eta=0 with no unconstrained adjustments. The suppression of R_{CP} observed
at high \eta is understood as the simple consequence of the reduction of the
soft parton density on the deuteron side compared to that on the gold side. The
effect of momentum degradation responsible for baryon stopping is also
considered. The asymmetry of backward-to-forward spectra can be reproduced
within the same framework without any change in the basic physics.
