Abstract

Conventional agricultural intensification, driven by global demand, poses significant environmental and sustainability threats to the Philippine cacao sector. This study investigates the adoption of sustainable agricultural practices (SAPs) using a Theory of Planned Behavior framework; and the partial least squares structural equation model and multivariate probit model based on a survey of 271 farmers. Results reveal complex adoption patterns; while high-yielding varieties and irrigation show complementarity, substitution occurs between labor-intensive practices. A key theoretical finding is that perceived ecological benefits influence intention both directly and indirectly, yet personal attitude lacks a statistically significant direct effect on adoption intent. This suggests that adoption is driven more by social norms and structural constraints such as land ownership, income, and irrigation; than by individual preference. These findings emphasize that policy should address specific socio-economic barriers and resource interdependencies to foster long-term SAP adoption.
