Vegetated earth-banked terraces
In Spain earth-banked terraces are constructed on moderately gentle slopes by agricultural machines to reduce slope gradient and length and improve soil organic matter and structure. Terraces reduce the formation of gullies and retain water from upslope and often stones are used to reinforce the terrace ridge. The terrace ridges are optimal locations to plant olives, almonds or fruit trees, trees, shrubs and grasses adapted to semi-arid conditions. 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.
