Linkages of proximate causes and underlying factors
The past studies on deforestation in the tropical regions showed that there are not multiple proximate causes and underlying factors, but also in most cases the interactions of multiple underlying factors drive multiple proximate causes.
In this case study, political and territorial strategies to integrate Khmer Rouge to end the long standing civil wars in Cambodia, the need for socio-economic development for the demobilized military families, and populated poor families with saturated paddy lands drove agricultural expansion and intensification and the improvement of roads infrastructure in the Northwestern regions.
Access to agricultural technologies such agro-chemicals and machineries, high variation of rainfall and soil degradation led to the changes of land use for instance shifting from annual upland crops such as maize and cassava to fruit trees like mango and Pailin longan. These two kinds of fruit trees sustain very well with depleted soil and drought. Furthermore, it could be stimulated the production using agro-chemicals to schedule the harvest at premium price.
