RESUMEN
Agriculture is a main driver of land-cover change globally resulting in decreased biodiversity, increased carbon emissions, and land desertification. Environmental best management practices reduce risk to the environment caused by agricultural operations. However, the adoption of environmental best management practices by farmers often is lower than what would be possible. While prior studies have investigated determinants of environmental best management practices, it is not well understood how social psychological drivers of various best management practices may be modified by contextual factors. To help close this knowledge gap, we conducted a large-scale survey of Ontario farmers investigating how social psychological factors and resource constraints combine to determine adoption of farm forests, riparian buffers and windbreaks, and how these relationships are modified by farmer demographics and farm characteristics. We analyzed survey responses of 490 farmers with structural equation modeling using the Theory of Planned Behavior as theoretical framework. Our results suggest that perceived benefits of environmental best management practices are of relatively low impact on best management practice adoption. Beliefs of a personal obligation for adoption and the perception of the capacity for adoption consistently were of higher impact, with lack of labor as main constraint. The relationships of perceived benefits and social norms with adoption were modified by farmer income, education, and age, as well as by the distance between a farm and the nearest settlement. However, the relationship of control beliefs with adoption was not affected by any contextual factors. We conclude that the improvement of programs in support of labor availability may have positive impacts on the adoption of the investigated environmental best management practices.
