Northeast Nigerian Food System Data, 2020

This dataset captures household food system and food security conditions in Northeast Nigeria using a mixed-methods, transdisciplinary design. The core is a household survey (target = 400, realized n = 375) collected via multistage random sampling across two case-study states (Taraba and Gombe) during Feb–Mar 2020 (2 states, 4 agri zones, 8 LGAs ? 16 communities, 25 households each). Qualitative components comprise six focus group discussions and a stakeholder consultation (farmers, extension agents, agronomist, food scientist, agricultural economist) that informed causal loop diagrams (CLDs) and a system dynamics model. The survey covers demographics; crop–livestock production and diversity; labour and costs; markets and forest foods; income and expenditures; and food consumption with a Dietary Diversity Score (DDS) module following FAO/FANTA groupings. Data were cleaned and analysed with descriptive statistics and system-thinking tools (Vensim). Fieldwork followed ethics approval and COVID-19 safety protocols.
