Transcript

  • 1. Geography of Rotational Shifting Cultivation Landscapes in Northern Laos Andreas Heinimann, Kaspar Hurni et al. LIWG,VTE 29.3.2012 1
  • 2. 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, - - 1- 1.2 mio 1991 Chavez, 4.8 mio ha 20 % - 1994 (1981/1982– 1988/1989) Hanson 2- 2.5 mio ha 8.5 – 9.5% 1.8 mio 1998 LIWG, 29-3-12, Heinimann et al. 2
  • 3. Problems of detecting SC landscapes and accounting for population involved is not a Laos or SEA issue only LIWG, 29-3-12, Source: Mertz, Leisz, Heinimann, 2009 Heinimann et al. Why is there not more reliable data available?• 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) LIWG, 29-3-12, Heinimann et al. 3
  • 4. New approaches to detect shifting cultivation landscapes LIWG, 29-3-12, K. Hurni , et al, in prep Heinimann et al. K. Hurni , et al, in prep LIWG, 29-3-12, Heinimann et al. 4
  • 5. K. Hurni , et al, in prep LIWG, 29-3-12, Heinimann et al.Combined approach of medium spatial resolution satellite imagery with spatial low resolution but hyper-temporal characteristics LIWG, 29-3-12, K. Hurni , et al, in prep Heinimann et al. 5
  • 6. Approximation of shifting cultivation landscapes 2000 -2009 K. Hurni , et al, in prep LIWG, 29-3-12, Heinimann et al. Patterns of poverty and market accessibility in shifting cultivation landscapes LIWG, 29-3-12, A. Heinimann, et al, in prep Heinimann et al. 6
  • 7. Approximation of shifting cultivation landscapes and basic socio-economic characteristics 2000 -2009 LIWG, 29-3-12, A. Heinimann, et al, in prep Heinimann et al. Shifting cultivation landscapes - remoteness LIWG, 29-3-12, A. Heinimann, et al, in prep Heinimann et al. 7
  • 8. Shifting cultivation landscapes – Ethnolingusitic families LIWG, 29-3-12, A. Heinimann, et al, in prep Heinimann et al. Socio-geography of shifting cultivation landscapesNote: ..below.. means: better off then national rural average A. Heinimann, et al, in prep LIWG, 29-3-12, Heinimann et al. 8
  • 9. Shifting cultivation landscapes & land concessions Source: CDE, MoNRE, GIZ Preliminary results; do not cite 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 LIWG, 29-3-12, Heinimann et al. 9
  • 10. Last, but crucial note:The importance of proper integration of rotational SC in village level land use planning LIWG, 29-3-12, Heinimann et al. Facilitate Information Access & Coordination: Online Land Use Planning platform LIWG, 29-3-12, Heinimann et al. 10
