2.1 技术简介

技术定义:

Old motor tyres and/or vegetation along contours.

2.2 技术的详细说明

说明:

The site of Geen Einde is typical of many areas in Lebowa: a large gully approximately 200 m wide and 10 m deep in places with semi-eroded pedestals remaining. Flood waters from the mountain meanders causes further gouging of the sides of the pedestals. Tributary gullies have formed in the highly erodible soil (high clay content) adjacent to the main gully. Signs of old contour bunds indicate that the land was cultivated in the past.
1. An earth silt dam was mechanically constructed across the main erosion gully.
2. Several gabion structures were constructed in the minor gullies.
3. Vetiver grass was planted in the silt to act as nursery material for future planting.
4. Old motor tyres were laid on a level contour above the minor gullies to harvest water.
5. Several species of indigenous trees were planted in the gullies and along the rows of tyres.
6. Two Agave species, local aloes and vetiver grass were planted along level contours.
7. Agave was planted along the edges of the gullies.
8. Shallow gullies were stabilised with old tyres and Agave.
9. Couch grass (Cynodon dactylon) was planted at a few places in the gullies and along the rows of tyres.
The main reason for these actions was to reduce the water velocity.

• 在实验/研究期间

注释（项目类型等）:

Having read about the success achieved by placing stone barriers on a level contour in other parts of Africa, but also being aware that the process is slow and laborious and dependent on the availability of stones, the thought come to mind to use old motor tyres instead.
First in the area (my original idea).

3.1 该技术的主要目的

注释:

Major land use problems (compiler’s opinion): Severe environmental degradation (less graze cover over grazing, considerable silt in the river going into Olifants river a main resource for Kruger National Park, below gabion construction were silted up in one year (some even in one rainstorm).

Major land use problems (land users’ perception): Poverty, land tenure free range for the whole community

Semi-nomadism / pastoralism: Yes

Grazingland comments: The area was not fenced off at all.

Selective felling of (semi-) natural forests: Yes

Clear felling of (semi-)natural forests: one of the reason for erosion

Problems / comments regarding forest use: So far only indigenous trees have been planted, but there are many exotic species that can also be investigated. For example, the carob can be tried as a commercial crop, the mulberry as a fodder and fruit crop.

Forest products and services: fuelwood, grazing / browsing, other forest products / uses (honey, medical, etc.)

Type of grazing system comments: The area was not fenced off at all.

Constraints of settlement / urban: scattered

Number of growing seasons per year: 1
Longest growing period in days: 210
