Eradicating hunger and achieving food security remain major challenges to humanity and to sustainability, and are being exacerbated by the COVID-19 pandemic. To support the UN system’s efforts towards eliminating hunger, UN DESA is holding a global policy dialogue on food security in the context of demographic change and rural development. Internationally renowned experts and professionals on food systems, population trends and rural development will be invited to discuss this urgent and multidimensional issue. The event also will serve as a UN Food Systems Summit Dialogue aligned with Action Track 4 — Advance Equitable Livelihoods and Value Distribution, giving participants an opportunity to contribute to designing the food systems of the future by informing the process of the 2021 Food Systems Summit.
