3. Classification of the SLM Technology

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

Grazing land

Grazing land

Extensive grazing:

Intensive grazing/ fodder production:
  • Cut-and-carry/ zero grazing
Forest/ woodlands

Forest/ woodlands

Products and services:
  • Timber
  • Fuelwood
  • Nature conservation/ protection
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

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.
