2.1 ຄໍາອະທິບາຍສັ້ນຂອງ ເຕັກໂນໂລຢີ

ການກຳໜົດຄວາມໝາຍ ຂອງເຕັກໂນໂລຢີ:

Earth-banked terraces in cereal and almond cropland covered with drought-resistant shrubs.

2.2 ການອະທິບາຍ ລາຍລະອຽດ ຂອງເຕັກໂນໂລຢີ

ການພັນລະນາ:

Earth-banked terraces are constructed by carefully removing a superficial soil layer (~10-20 cm) from one part of a field, concentrating it on the lower end of that field in order to reduce slope gradient and length. Another terrace is created directly downslope to form a cascade of terraces. Terrace risers have to be of restricted height (~50-150 cm) to prevent steep and unstable terraces. Stones from the fields can be used to reinforce the terrace ridge. After terrace construction, fields should be gently sloping (<3%) in the direction of the main slope. The distance between terraces must be enough to allow tractor movement during normal cultivation activities and it depends also on the slope gradient. The steeper the slope, the shorter is the distance between terraces. Terraces reduce the formation of gullies and retain water from upslope. The terraces are made with locally available machinery (tractor, small bulldozer). The terrace ridges are optimal locations to plant olives, almonds or fruit trees. Moreover, to be most effective, the terrace ridges are vegetated with shrubs adapted to semi-arid conditions and with a good surface cover (>~30%) throughout the year (e.g. Stipa tenacisima, Rosmarinus officinalis, Thymus vulgaris, Ulex parviflorus, Rhamnus lycioides, Pistacia lentiscus). Natural regeneration of vegetation is allowed without limitation on the terrace ridges, so no herbicide application or burning are carried out to remove weeds. Where possible, regeneration should be stimulated by planting the same adapted species in at least 25% of the terrace ridge. Optionally, in the other 75% of the terrace ridge, cereals or other leguminous species can be sown, but should not be harvested or used for grazing.

Purpose of the Technology: This technology reduces flooding, damage to infrastructure and siltation of water reservoirs, while maintaining (or slightly increasing) crop productivity. This is achieved by reducing runoff, soil erosion and hydraulic connectivity through a decreased slope gradient and an increased vegetation cover. The terrace ridge functions as a sink for runoff within fields and reduces runoff velocity. The vegetation leads to increased soil organic matter content below plants, producing an improved soil structure and a higher infiltration capacity. The use of stones from the fields to reinforce the terraces is optional, but facilitates crop production in the fields and makes the ridges more resistant to higher runoff velocities. The technology requires an initial investment in the construction of the terraces. Terraces can best be located on thalwegs and on areas where gully formation is often observed. Maintenance consists of filling up possible bank gullies developed in the terraces after important rainfall events and, if needed, substitute decayed shrubs with new ones.

Natural / human environment: The technology is generally applied on soils of shallow to medium depth (20 – 60 cm), and slopes are gentle to moderate (5-15%). The climate is semi-arid with a mean annual rainfall around 300 mm. Droughts, peaking in summer commonly last for more than 4-5 months. Annual potential evapotranspiration rates larger than 1000 mm are common. The production system is highly mechanized and market-oriented but depends strongly on agricultural subsidies. All cropland is privately-owned.

ຄວາມຄິດເຫັນ (ປະເພດ ໂຄງການ ແລະ ອື່ນໆ):

Most of the earthen terraces are already much older than 50 years. Recently, the regional administration is promoting clearly defined vegetated strips with minimum dimensions in order to apply for subsidies.

3.2 ປະເພດການນໍາໃຊ້ທີ່ດິນ ໃນປະຈຸບັນ() ທີ່ເຕັກໂນໂລຢີ ໄດ້ຖືກນໍາໃຊ້

ຄວາມຄິດເຫັນ:

Major land use problems (compiler’s opinion): A lack of water availability seriously limits the production potential of the soil and results in a low vegetation/crop cover. The relatively high soil erosion rates cause various off-site related problems (i.e. flooding, reservoir siltation) and on-site problems (i.e. gully formation and loss of soil depth).

Major land use problems (land users’ perception): Lack of water for irrigation of crops limiting the crop types that can be planted as well as the crop yield of dryland farming.

This technology is very effective at reducing surface runoff and erosion by reducing slope gradients and connectivity. In addition, it has a water harvesting effect. So it reduces on-site and off-site erosion problems and potentially increases water retention in the fields. How can they be sustained / enhanced?
