Permanent meadows or pastures are more effective in controlling land degradation than arable cropping. They are especially appropriate in hilly regions on sloping land where the risk of water erosion is high.
Peak flow control structures are designed to reduce flow velocities and quantities running down from catchment areas. Leaky dams are peak flow control structures that are made of wood and allow low flows to pass through, but hold back high flows, thus providing temporary storage and enhanced infiltration of flood …
Permanent grass cover under grape vines protects the soil surface against erosion and compaction - and provides better conditions for traffic within the rows during mechanised field operations
