Bioversity International (“Bioversity” for short) is the world’s largest organization undertaking research on agricultural biodiversity, dedicated to addressing global issues related to food security, poverty, climate change and environmental degradation. We are a non profit organization, active in over 100 countries worldwide, with more than 350 staff working from some 16 country offices. We are one of 15 centres of the Consortium of International Agricultural Research Centres (CGIAR). This is an exciting time to join Bioversity International. We have recently developed new and ambitious goals, clear objectives and performance indicators for the next ten years. Two strategic priorities have been set ‐ to improve the use of biodiversity by smallholder farmers and the conservation of plant diversity. For further information on Bioversity International, consult the Web page at http://www.bioversityinternational.org Background The Nutrition and Marketing Diversity Programme of Bioversity International has a programme on the use of biodiversity resources for improved food and nutrition. Bioversity’s research is designed to explore how biodiversity conservation and use can provide immediate local as well as global benefits to people, especially in developing countries facing a growing burden of over and under nutrition. Agricultural biodiversity including crop genetic diversity, neglected or underutilized crops, plants and animals in smallholder agriculture and in a range of niches including aquatic environments and forests) is an important a source of nutrients, food components and dietary diversity. Agricultural biodiversity is also crucial to address shifts towards uniform, simplified, and nutritionally poor diets. Bioversity seeks to fill the international post of Senior Scientist in Nutrition with expertise in human nutrition to work in a team focusing a global research programme investigating sustainable diets and how agricultural biodiversity can contribute to improved nutrition and health. The incumbent would collaborate in research that (i) provides systematic evidence of the links between agricultural biodiversity, dietary diversity and relevant health outcomes; (ii) documents the role of local foods, local food culture and traditional knowledge of plants and foods; (iii) identifies strategic options and pathways that mainstream biodiversity into cross-cutting policy and development agendas in agriculture, health, and environment.
