Forests constitute about 60 per cent of Cambodia’s total area corresponding to approximately 10 million hectares. Cambodia’s national forest programme developed in 2010 includes various sub-programmes dealing with the demarcation and classification of forests, national forest management and conservation, forest law enforcement and governance, community forestry and sustainable forest financing. Land tenure issues have become a major concern for efficient and sustainable forest management due to overlapping areas and unclear or unavailable boundaries in place. The demarcation for long-term forestland management and agricultural or industrial development has become a priority for Government, yet there is limited practical implementation thus far. Through a participatory process, LTS evaluated ‘cost and time-effectiveness’ of forest demarcation results undertaken in 6 pilot areas and formulated a practical manual for forest demarcation for Cambodia to be used for forest demarcation throughout the country.
