Intervention

EXPERIMENTAL

The intervention group will receive capacity building sessions on the 'Promotion of a biodiverse diet' and will include both Agriculture and Nutrition topics, in addition to access to routine health and nutrition checks, and agriculture extension as offered by commune and provincial staff as normal. 5 Sessions will be held in each village over 12 months.

Behavioral: Promotion of a biodiverse diet

The control group will continue to receive routine health check and nutrition education from health staff at commune health facilities. Access to agriculture extension services as offered by provincial staff will also continue as normal.

Interventions

Promotion of a biodiverse diet BEHAVIORAL

Nutrition education combined with Agriculture Capacity building focused on a key set of nutritious crops. Component (C) 1 - Participatory Identification of Intervention Approach (PIIA); C2 - Local stakeholder consultation; C3 - Sensitisation of community; C4 - Formation of Diversity club.
