2.1 Краткое описание Технологии

Определение Технологии:

Stone faced terraces are commonly constructed on cultivated lands. These are structural measural measures placed along the contour to control soil erosion and trap runoff.

2.2 Подробное описание Технологии

Описание:

Stone-faced soil bund is constructed during the dry period when the field is free from crops (after crop harvest). Soils in the woreda are light and are easily eroded. A contour line is marked on the ground first and a foundation placing stones is dug. The stone wall is placed in the foundation and the wall is raised until it attains a height of 0.50m at minimum. Then earth is dug on the upslope side by removing soil from it and make an embankment of soil on the upper side to support the stone wall. In the same way the stone is supported by the soil from the upper side. The embanked soil is lightly compacted to avoid collapse. The objective is to control concentrated runoff from causing soil erosion and to retain as much rainwater as possible in the soil for mazimizing crop production. Livestock are not let on the terraced land. Most land users feed their animals tethered. The bund is then stablized by planting grass. The most commonly used grasses for stablizing bunds in the area are phalaris and elephant grass. The purpose is to control runoff and soil erosion from cultivated lands. Grass is planted to stablize the bund and also help in providing fodder for animals. Some land users stablize the stone-faced bunds by planting fruit trees. Fruit trees are often planted at the homesteads for better management and protection. The income obtaoned from fruit trees is high. Sorghum fields are predominantly treated by stone-faced bunds while chat and coffee fields are treated by ridges and basins. Frequent maintenance and upgrading is required until bench is formed. Currently most of the fields in the woreda have a properly stablized terraces and as a result loss of soil and water by erosion is decreasing. Maintenance is done continuously until the structure stablizes well and inparticular after heavy rains, every time after tillage and cropping. The technology is suitable in areas where stones are avialable and soils are light.

3.1 Основные цели и задачи реализации Технологии

• повышение производства
• снижение или предотвращение деградации земель, восстановление нарушенных земель

3.2 Текущий(-ие) тип(-ы) землепользования на территории, где применяется Технология

Пояснения:

Major land use problems (compiler’s opinion): Land use problem is the result mainly of high population growth, improper land use and poor farming practices. Land not suitable for cultivation is put under use. Steepslopes on hillsides and mountain escarpments are cultivated. These have resulted in high runoff and sediment movment from the upper catchments which are dominantly devoid of vegetation and no conservation measures practiced.

Major land use problems (land users’ perception): land shortage, loss of fertility and soil erosion on lands with no conservation measures.

Cut-and-carry/ zero grazing: grazing land is seriously shriniking owing

Type of cropping system and major crops comments: sorghum-beans or chat - sorghum, maize-beans
