Abstract
We review the effect of shearing on transport and the formation of transport barriers. The focus is primarily on laboratory plasmas where the formation of transport barriers (the L-H transition) is thought to originate from the turbulence regulation due to both (coherent) mean and (random) zonal flows. We provide quantitative discussion on the reduction of turbulent transport by these flows and elucidate their roles in the barrier formation.
