Water harvesting from concentrated runoff for irrigation purposes

Water shortage is one of the most limiting factors for sustainable agriculture in large parts of South East Spain. Part of the solution of this problem may come from the restoration of traditional water harvesting structures. This technology describes small earthen or stone-built bund that diverts flood water, during runoff events, from intermittent streams towards nearby cultivated fields. The diverted water will temporarily flood the fields and provide the crops with water. Depending on the slope gradient and the amount of water to be harvested, the fields are organised as single terraces, or as a staircase of terraces. Water is diverted from one terrace to the next through small spillways in the terrace. The goal of this technology is to increase crop yield. In addition, these structures help to reduce the intensity of floods and reduce the damage caused by them by reducing runoff volume in intermittent streams.
