2.1 技术简介

技术定义:

Ancient level bench terraces with stone walls, built to stabilise slopes, retain moisture, and create a suitable environment for horticulture.

2.2 技术的详细说明

说明:

Stone wall bench terraces in the hill ranges of western Syria comprise an ancient indigenous technology, introduced by the Romans and Byzantines about 2,000 years ago. Some new terraces are, however, still being built. The walls are constructed with limestone, largely found on site. The terraces are located in steep terrain (usually on slopes more than 25%) under low (and erratic) rainfall regimes of between 250 and 500 mm per annum. The terrace walls are 1-2.5 m high and the level beds 3-25 m wide, depending on slope.
Deep soil profiles (more than 2 m) have developed on steep slopes, where original soil depth was only shallow to medium. The terraces are very efficient in preventing soil erosion and in the retention of rainfall. They support trees and annual crops where they could not otherwise be grown.

These terraces are usually found near settlements. Construction is very labour intensive, considering how little land is effectively protected from erosion and brought into cultivation. High labour investment makes the construction process slow and retards further extension of the technology. However, if soundly constructed, maintenance requirements are low. Underlining this point, a large number of very ancient terraces can still be found intact, supporting a productive crop. Sometimes localised collapse of a terrace occurs due to concentrated runoff. In that case, the terrace in question may need to be rebuilt. To prevent such breaches, it is important to allow for discharge of excess runoff along drainage lines.

Currently, most terraces are used to grow fruit trees. These include olives, cherries, almonds, plums, pomegranates, apricots, and peaches. Husbandry practices are normally carried out by hand. Where space permits, however, draft animals are used for tillage. The curves of the terraces and access to the steep slopes make it very difficult/impossible to use tractors. Animal power is more versatile in this irregular landscape, but it is more expensive than tractor power, due to shortage of fodder.

注释:

Major land use problems (compiler’s opinion): Before terracing, water erosion resulted in shallow to medium colluvial soils. Terracing made cultivation possible, but the
beds tend to be very narrow and/or irregularly shaped, with large boulders set in them, making tractor cultivation (which is cheap) impossible.

Major land use problems (land users’ perception): (1) Soil tillage - mechanization is difficult; animal power is up to 5 times more expensive than tractor power.
(2) Rockiness of the soil - large and very large stones make cultivation difficult.
(3) Accessibility - inadequate road network to reach fields

Manual construction work requires 0.35-0.7 person days per metre length of terrace wall. Establishment costs were calculated for an average of 600 m length of stone wall (height 2 m, width 70 cm) per hectare on a 12% slope, with
terrace beds therefore about 16-17 metres wide. Narrower terraces on steeper slopes are considerably more expensive to construct.
