1.3 关于使用通过WOCAT记录的数据的条件

编制者和关键资源人员接受有关使用通过WOCAT记录数据的条件。:

是

2.1 技术简介

技术定义:

Pasture management and improvement through weeding comiphora

2.2 技术的详细说明

说明:

The comiphora trees are ring barked at 2 feet high for the whole plant to die. This gives room for desired species to grow, retain moisture and add soil fertility through its decay. The land can also be given surface treatment through contour shallow ripping and dispersed grass seeding with desired species.

5.1 气候

5.2 地形

关于地形的注释和进一步规范:

Slopes on average: Not more than 8%

5.3 土壤

如有可能，附上完整的土壤描述或具体说明可用的信息，例如土壤类型、土壤酸碱度、阳离子交换能力、氮、盐度等。:

Soil texture: Coarse/ light (sandy) with tiny stones

Soil fertility is medium with controlled erosion

Topsoil organic matter is low due to limited vegetation cover

Soil drainage / infiltration is good because of sandy soil

Soil water storage capacity is low

5.6 应用该技术的土地使用者的特征

说明土地使用者的其他有关特征:

Population density: 10-50 persons/km2

Annual population growth: 2% - 3%

100% of the land users are average wealthy and own 100% of the land.

Off-farm income specification: most of the landuser depend on the farms

在所有采用这项技术的人当中，有多少人是自发的，即未获得任何物质奖励/付款？:

• 91-100%

注释:

2% of land user families have adopted the Technology without any external material support

7 land user families have adopted the Technology without any external material support

Comments on spontaneous adoption: estimates

There is a little trend towards spontaneous adoption of the Technology

Comments on adoption trend: men land owners ring bark comiphora as they graze animal. Usally they are 50-60 years old and those with many.
