Sources of knowledge on shifting cultivation?
Mainly case studies & anecdotal information
LIWG, 29-3-12,Heinimann et al.
What about the national level information on dimension of shifting cultivation in Laos?
Who Area % territory Population
Fujisaka, 1991
- - 1- 1.2 mio
Chavez, 1994(1981/1982–1988/1989)
4.8 mio ha 20 % -
Hanson 1998
2- 2.5 mio ha 8.5 – 9.5% 1.8 mio

Problems of detecting SC landscapes and
accounting for population involved is not a Laos or SEA
issue only

• National land cover inventories do not depict shifting cultivation landscapes as a class (as technically not standard and political bias in classification)
• Population Census do not depict any information related to shifting cultivation
• Agricultural Census does not provide consistent information related to non permanent form of agriculture (FAO standard)
• No standard approach in Remote Sensing to detect rotational land use systems (only land cover)
Why is there not more reliable data available?

Some Conclusions
• The approach may be suitable for first tier operational monitoring at landscape scale (but needs further testing and validation)
• Shifting cultivation is still widespread with considerable shares of the population living in shifting cultivation landscapes
• Anecdotal information and case studies are confirmed that SC landscapes are marginal from various perspectives (remoteness, poverty, ethnicity) when considering the entity of northern Laos
• This marginality is even increased over time as the SC landscapes that “disappear” are in tendency in less marginal regions
• This multi-marginality gives raise to doubts if these regions can profit from the ongoing increase in rural accessibility and market integration, as it may not only be a question of accessibility but actual access to e.g. markets or other services that are limiting
