Methodological challenges in assessing the viability of agroecological practices: lessons from a multi-case study in Africa por Andrieu, N., Dedieu, B., Girard, P., Scopel, E., Magaju, C., Dembele, C., Mekuria, Wolde, Coe, R.

“…Seven methodological challenges discussed are (i) defining an object of study through a list of practices or agroecological principles, (ii) having a practice-based assessment versus a systemic assessment at field or farm scales, (iii) having a subjective assessment of the viability of agroecological practices based on farmers’ perspective or an “objective” assessment, (iv) having a qualitative or quantitative assessment, (v) having a diachronic versus synchronic assessment, (vi) having a multisite approach versus a single-site study, and (vii) having a context-specific assessment method or a unitary assessment method. …”
