2. Descripción de la Tecnología MST
2.1 Breve descripción de la Tecnología
Definición de la Tecnología:
Activities that help maintain the productive potentials of soils through prevention and reduction of erosion, enhancing of rehabilitation rate by practicing measures such as microbasins, trench, eyebrow terrace, terraces, pitting and plantation of trees.
2.2 Descripción detallada de la Tecnología
Descripción:
The SWC technology comprises a combination of measures, which include agronomic, vegetative, structural and management measures. This means that in implementing the SWC technology combination of measures such as contour cultivation, grass strips, soil and stone bunds, area closure and improved grazing are applied in integration to rehabilitate degraded lands and restore their productivity. The purpose is to improve food security by reducing erosion and enhance the productivity of land by planting useful trees and fodder species. Unproductive land is changed to productive land by the practicing of the technology. The SWC technology is continously maintained and improved to meet the standards and qulity such that erosion is minimized. The technology is suitable to degraded and unproductive lands which were abondoned as result of low productivity and were previously under cultivation or grazing land. Closure of the area is followed by vegetative and structural measures to speed up the recovery / regeneration rate.

3. Clasificación de la Tecnología MST
3.1 Propósito(s) principal(es) de la Tecnología MST
- mejorar la producción
- reducir, prevenir, restaurar la degradación del suelo
3.2 Tipo(s) actuales de uso de la tierra donde se aplica la Tecnología
Tierras cultivadas
- Cosecha anual
Cosechas principales (comerciales y de subsistencia):
Major cash crop annual cropping: Pepper
Major food crop annual cropping: Maize, teff
Major other crop annual cropping: Sorghum
Major cash crop perennial (non-woody) cropping: Chat, coffee
Major cash crop tree/shrub cropping: eucalyptus
Cultivos asociados (cultivos/ pastoreo/ árboles), incl. agroforestería
- Agro-silvopastoralismo
Comentarios:
Major land use problems (compiler’s opinion): Improper landuse, defforestation, overgrazing, lack of action to control erosion.
Major land use problems (land users’ perception): lack of awarness, traditional way of ploughing, lack of technolog on SWC
Semi-nomadism / pastoralism: open grazing is practiced
Grazingland comments: Nowadays closing a small individual plots and practicing cut and carrying system is being popular among land users.
Plantation forestry: replacing natural forests
Problems / comments regarding forest use: Forest/woodlands are mainly communal, so, replanting forests is undertaken by the community. Individual forests/woodlands are very few and small in size since there is a shortage of land for forests and tree plantation.
Forest products and services: timber, fuelwood, fruits and nuts, nature conservation / protection
Type of cropping system and major crops comments: Haricot bean is planted after maize is planted and has allowed some height.
Constraints of infrastructure network (roads, railways, pipe lines, power lines)
Constraints of Stone excavation (quarrying has caused a lott of damage on land.)
