Citizen H2D3 - Citizen-driven Individual/ Household Dietary Diversity Dynamics

Citizen-H2D3 is envisioned as a critical step towards generating real-time insights on diets for government agencies, NGOs, and the scientific community. Citizen-H2D3 will be an unprecedented platform for citizens to spontaneously report their diet diversity, quantity purchased and expenditure on food groups, driven by gamified micro-payments that minimises the costs of data acquisition and optimises data robustness. The system will be set-up to motivate volunteers to regularly submit data, with sufficient controls to allow for non-dominant participation. By collaborating with the newly created Rwandan national program on nutrition, and moving beyond utilisation of periodic surveys and recall diaries, Citizen-H2D3 will be responsive to users’ demands and provide a unique opportunity for data collection through alignment with regional priorities on digitalisation of food systems and demonstrate the potential use of digital tools in tracking (and eventually) addressing malnutrition.
