2.1 Short description of the Technology

Definition of the Technology:

level bund with double stone walls with soil and grass to stabilize the structure

2.2 Detailed description of the Technology

Description:

Two level rows of stones are piled up and the space between them is filled up with soil. Grass is growing on it so it can stabilize the bund. The soil can accumulate behind the bund. The land and the bunds slowly develop into terraces. It is combined with contour ploughing.

Purpose of the Technology: control runoff and soil erosion

Establishment / maintenance activities and inputs: through food-for-work program. Maintenance is up to the farmers, some maintain it regularly, throughout the year, others don't.

Natural / human environment: on gentle and steep slopes

3.2 Current land use type(s) where the Technology is applied

Cropland

• Annual cropping

Annual cropping - Specify crops:

• cereals - barley

• wheat, emmer wheat, teff

Number of growing seasons per year:

• 2

Specify:

Longest growing period in days: 150 Longest growing period from month to month: Jul - Nov Second longest growing period in days: 150 Second longest growing period from month to month: Feb - Jun

Grazing land

Animal type:

Comments:

Major land use problems (compiler’s opinion): erosion, decline of soil fertility and yield decline other major SWC specialist: shortage of grazing land and of forage

Major land use problems (land users’ perception): erosion, runoff, drought, climate

Grazingland comments: area closure: only during July-October some areas are closed, otherwise no area closure any more. Make hay for the cattle to feed them in the dry season.

4.1 Technical drawing of the Technology

4.2 General information regarding the calculation of inputs and costs

other/ national currency (specify):

birr

If relevant, indicate exchange rate from USD to local currency (e.g. 1 USD = 79.9 Brazilian Real): 1 USD =:

8.8

4.3 Establishment activities

4.5 Maintenance/ recurrent activities

4.7 Most important factors affecting the costs

Describe the most determinate factors affecting the costs:

the slope: the steeper, the more bunds are needed; labour is a problem if there is no food-for-work any more

5.1 Climate

5.2 Topography

Comments and further specifications on topography:

Landforms: Hill slopes (ranked1, mainly steep hills), footslopes and ridges (both ranked 2)
Slopes on average: Hilly (ranked 1), rolling (ranked 2, more than 80% of the land has a slope degree from over 13%) and steep (ranked 3)

5.3 Soils

If available, attach full soil description or specify the available information, e.g. soil type, soil PH/ acidity, Cation Exchange Capacity, nitrogen, salinity etc.

Soil depth on average: Very shallow (about 40% of the area) and moderately deep (both ranked 1), shallow and deep (both ranked 2)
Soil texture: Fine/heavy (of the major soil type)
Soil fertility: Medium
Topsoil organic matter: High (ranked 1, in the major soil type) and medium (ranked 2)
Soil drainage/infiltration: Medium (ranked 1) and poor (ranked 2, somtimes there is waterlogging)
Soil water storage capacity: Low (ranked 1) and medium (ranked 2)

5.6 Characteristics of land users applying the Technology

32% of the land users are poor and own 26% of the land (only rough estimates).
Off-farm income specification: farmers employ others for ploughing, so they can go to the market
