2.7 Introduction of the Technology

Specify how the Technology was introduced:

• through projects/ external interventions

Comments (type of project, etc.):

The farmers wanted to test grasses that can withstand high water content. This is the first time we test theese methods.

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

Comments:

Major land use problems (compiler’s opinion): The subsidence and oxidation of the organic material in the peat soils makes the cultivated fields less drained and eventually it is impossible to grow crops there and the trafficability gets worse. The oxidation of the organic material release CO2 and N2O to the atmosphere.

Major land use problems (land users’ perception): Decreased yield and trafficability

Ranching: Yes

Cut-and-carry/ zero grazing: Yes

Forest products and services: timber, fuelwood, nature conservation / protection

3.7 Main types of land degradation addressed by the Technology

Comments:

Main type of degradation addressed: Ps: subsidence of organic soils, settling of soil

Main causes of degradation: other human induced causes (specify) (Drainage)

Secondary causes of degradation: population pressure (During 19th century these soils were drained to improve the food production.)

3.8 Prevention, reduction, or restoration of land degradation

6.7 Strengths/ advantages/ opportunities of the Technology

Strengths/ advantages/ opportunities in the land user’s view
He can get an incom from his fields even though the ground water level is too high for his normal production.

Strengths/ advantages/ opportunities in the compiler’s or other key resource person’s view
The farmer do not have to abandon the field due to high groundwater table.
These soils will leak GHG until they are completely under water. With the technology we at least get something good from the fields.
