Protocol / published information

Protocol overview

No cascade-effect estimates are reported. Heat to Harvest proposes to study how heat-related physiological strain and work patterns relate to harvests and child nutrition.

Study design & setting

Study design and methods

Population, setting or evidence base

Nouna, Burkina Faso, and Siaya, Kenya. Prospective cohort protocol, nested in existing HDSS infrastructure; Nouna includes a cool-roof trial comparison. Planned feasibility phase: 210 participants across 25 villages; farming households with children under 5.

Methods

Combines wearables, GPS, environmental sensors, household surveys, anthropometry and satellite yield models; planned multilevel, structural-equation and mediation analyses.

Limits to interpretation

Limitations

Heart rate reflects exertion and heat. Rainy-season sampling, selected households, sensor missingness and unmeasured agricultural factors constrain interpretation.

Research relevance

Connects climate exposure, livelihoods, food production and health within the same households.
