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:

It is a mechanical conservation measure where a basin and a ridge are formed for planting chat along a contour

2.2 技术的详细说明

说明:

A contour line is maked and a pit (trench) is dug and the soil embanked on about 75x50 cm. Chat cuttings are planted on the trench. The purpose of the technology is to collect as much water as possible. The embankment protects soil from erosion. Water is collected in the trench. Households using family labour make the ridge bund. During cultivation the ridge is strengthend. Maintenance is done in case of breaks on the ridge.The technology is suitable to semi-arid with rainfall 500-700 mm/annum. Farmers grow chat as the main means of finance/capital generation. Cultivation is done twice or three times.

注释:

Major land use problems (compiler’s opinion): land shortage, continuous cropping, land degradation, open grazing.

Other grazingland: Tethered/stall feed: grazing land shortage forced to tethered feeding and stall keeping.

Other grazingland: free grazing

Grazingland comments: Livestock (cows, goat) are mostly stallfed. In lower parts of the technology area livestock are let to graze openly. This part is a very dry area and there is large area for grazing. Goats browseon open woodlands that have acacia trees.

Problems / comments regarding forest use: The woodlands are getting extremely denuded as a result of heavy exploitation such as charchoal making, cutting trees for fuel wood and overbrowsing.

Forest products and services: timber, fuelwood, grazing / browsing

Type of cropping system and major crops comments: sorghum, ground nut
