Dataset for: GCBC midline household survey on native potato and mashua diversity, climate events, food security and social capital in Peru and Ecuador (2026)

This dataset contains the midline household survey of the project 'Andean Crop Diversity for Climate Change' (GCBC), carried out in 2026 with 110 farming households that grow native potato and/or mashua in three Andean sites: Cotopaxi and Chimborazo, Ecuador (n = 47); Quilcas, Junín, Peru (n = 37); and the Potato Park, Pisac, Cusco, Peru (n = 26). Households are classified by their level of involvement with the project: P, households conducting participatory trial plots; M, households taking part in evaluations, field days, meetings or seed exchanges; and N, non-participant households of the same or neighbouring communities (P 21, M 44, N 45).

The questionnaire covers household composition and income sources, land and fields planted with potato and mashua (area, tenure, irrigation), livestock (Peru only), the native potato and mashua varieties named by the household (up to five per crop), eight climate events in the last 12 months with their severity and impact on crops, the coping strategies used, household dietary diversity (HDDS, 10 food groups with frequency and source), months of food scarcity, membership in organizations, community activities and support networks, and training demand.
