2.1 Descrição curta da tecnologia

Definição da tecnologia:

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 Descrição detalhada da tecnologia

Descrição:

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.

Comentários:

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
