Brief summary

Agricultural biodiversity can have an important role in improving diet diversity, quality and nutrition and can be seen as the foundation of the food and nutrition value chain. Increasing the availability and access to local agricultural and/or wild biodiversity genetic resources has the potential to increase production, making more food available for consumption as long as entitlements to access it exist. However, as the history of food security interventions has shown, increasing the production and supply of staple crops alone is not enough to improve food security or nutritional status. However, while agricultural diversification is an important component, it is not alone sufficient to improve diet diversity. Other system elements including women's education and knowledge, intra-household dynamics and women's status and cultural beliefs and practices that improves children's health and nutrition are important to ensure biodiversity has a successful role in improving dietary diversity and quality.

Interventions

Component 1 - Participatory Identification of Intervention Approach (PIIA) Component 2. Local stakeholder consultation Component 3. Sensitisation of community Diversity club will receive capacity building from a Village health worker based on the prioritised species selected in component 2. The following topics will be covered for each species selected for promotion: 1. Where to locally source inputs and expected price 2. How/when to prepare plots using organic inputs 3. Planting and best-practice management practices 4. Seed saving and storage 5. Possible intercropping combinations OR ecosystem services provided Component 4. Active Cooking demonstrations and Nutrition Education and counselling: Diversified cooking practices

Inclusion criteria

* villages: Characterized as Thai village. Only Thai villages will be selected for the study as agriculture practices, diets, food preferences, language and cultures can change drastically between ethnic groups. * participants: i) Woman of reproductive age (between 15-49 years) who are the mother or primary caregiver of a child between 12 and 23 months of age. This age group is part of the critical 1000 day window for child development and marks the time when young children can potentially consume all foods from the household pot and consume a more diverse diet. As such, it is from this age group that biodiversity can have an effect on children's diets. ii) Both the woman and the child should be permanent residents in the village selected and do not temporarily migrate outside the village cluster during the year.

Exclusion criteria

* villages: Urban center of commune/province as these villages/cities do not have agriculture or home garden opportunities * participants: currently engaged in other agriculture or nutrition programme or intervention apart from what is offered by government extension workers
