Interactions between cattle raising & reforestation in the highland socio-ecosystem
of Nan Province, Northern Thailand: A companion modelling process
to improve landscape management

,
The need for co-management of renewable natural resources in Thailand
• Past administrative system:
• Centralized, bureaucratic & many often old sector agencies
• Decentralized management at sub-district level
since mid 1990s (Lakanavichian, 2006)
• New Tambon Administrative Organization (TAO) system • New Tambon Administrative Organization (TAO) system
• Still young: Need to improve dialogue & communication
• Increased complexity of interactions between
bio-physical & socio-economic dynamics
• Multiple stakeholders & decision making levels: how to coordinate?
• Rapidity of change: Requires adaptive management
• Urgent need for innovative approaches to support joint
management of resources & adaptive capacity of actors2
Forest conservation, farming & land use conflicts
• Specific government policies &
top-down enforcement:
• Recent increase in conservation areas
• Numerous reforestation schemes
• Expanding farm land in up- & highlands

Conclusions & perspectives
• It is possible to build a shared representation of a complex socio-ecological system with herders & foresters & use it to mitigate their conflict
• 2D simplified virtual landscape co-designed with actors was able to support collective decision making
• Simulation tools facilitated a collective reflection on • Simulation tools facilitated a collective reflection on existing practices & stimulated creativity
• Next steps:
– Collaborative research on the sustainable use of pasture
– Out-scaling: inside Doi Tiew village & other sites
– Transfer approach & adapt tools for teaching & training purposes
