Trees improve water storage and reduce soil evaporation in agroforestry systems

 Agroforestry can be defined as a dynamic, ecologically based, natural resource management system that, through the integration of trees on farms and in the agricultural landscape, diversifies and sustains production for increased social, economic and environmental benefits for land users at all levels. Terraces reduce the formation of gullies and retain water from upslope and often stones are used to reinforce the terrace ridge. This technology reduces flooding and minimise soil erosion through decreased slope gradient, it also improves soil organic matter by encouraging vegetation growth along the terrace ridges.
