    According to this study, a range of land management practices is available to help improve green water use efficiency. These practises can be classified according to their function. Hedgerow barriers and terraces can mitigate runoff; infiltration rates below hedgerows in Kenya were found to be three to eight times higher than where the crop was grown. Mulch that triggers soil fauna can improve water availability; mulching with straw from a local perennial grass in Burkina Faso doubled the water use efficiency from 1 kg mm-1 without fauna to 2 kg mm-1 with fauna.
