Brief summary

What is the role of Agricultural biodiversity in improving diet diversity, quality and nutrition?

Detailed description

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

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. Club will receive capacity building from a Village health worker. The following topics will be covered 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 and 4. Active Cooking demonstrations and Nutrition Education and counselling including Diversified cooking practices
