We study two nonlinear processes that are efficient in the spectral redistribution of Alfvén wave energy - second harmonic generation, and scalar decay. Both processes transport the energy of AWs towards smaller scales and/or higher frequencies, and can accelerate the energization of space plasmas implied by recent SOHO observations.
