Survey data on farmer mental models and fertilizer management practices in Madagascar

This dataset primarily contains mental model data and respondent characteristics from 485 households across five communes in the Irodo watershed (Anketrakabe, Ambolobozobe, Antsoha, Sadjoavato, and Anivorano). Using a stratified proportional sampling design, one adult per household rated how various factors influence fertilizer use decisions using the M-Tool (–3 to +3 scale). The dataset also includes detailed information on respondents and household characteristics (e.g., gender, education, land ownership) as well as household livelihoods, including primary and secondary activities.
