The study aimed to understand how the economic and environmental perceptions of upland farmers in the context of biofuels and natural rubber production regimes in Palawan explain their behavioral intents, especially regarding intensification of production and cooperation in such partnership regimes. Research findings reveal that upland farmers tend to equate high economic benefits with the wage labor opportunities and maintenance support offerred by these production partnership regimes. Using logistic regression models, the following economic and environmental variables are found to be significantly associated with upland farmers’ behavioral intents to intensify crop production and cooperate with new partnership regimes: socio-economic satisfaction; preference for high revenues; evaluative beliefs on soil productivity and remaining forest; place satisfaction concerning forest; past experiences; age and education.
