Diverse diets—rich in different grains, legumes, vegetables, fruits, nuts, and animal-source foods—are essential for meeting nutritional needs across the globe. This dietary variety depends on crop diversity, which underpins the world’s food systems, creating productive and sustainable agriculture and supporting resilience to climate change. Yet over the past century, food production and consumption patterns have become increasingly homogenized. A small number of crops now dominate global diets and agricultural systems, while thousands of edible plant species remain underutilized. Many of these edible species are nutrient-rich and well-adapted to local environments. At the same time, over 600 million people face daily hunger, over half of the world remains deficient in essential micronutrients, and the global rise of ultra-processed foods has contributed to increasing rates of diet-related non-communicable diseases.
Addressing these challenges requires reconnecting the foods people eat every day with the diversity conserved in genebanks and botanic gardens, as well as that maintained by farmers. It also requires bridging disciplines and communities that have often worked in isolation—agriculture and conservation, nutrition and health, and policy.
Crop Diversity Day 2026 will highlight cutting-edge initiatives working to transform food systems by leveraging crop diversity to deliver healthier, more sustainable and more equitable food systems. The event will bring together key actors from across the food and agriculture ecosystem—including policymakers, scientists, funders, and practitioners—to explore how diverse crops and foods can support better diets while strengthening resilience and livelihoods.
A central moment of the event will be the public launch of the updated World Food Map, a collaborative initiative that links dietary quality data with agricultural, environmental, and cultural information to provide a new global perspective on what people eat and why it matters. The World Food Map leverages the first global survey of what people eat, a major new source of data to understand what foods are commonly consumed, and to shed light on nutritional gaps in diets around the world. The World Food Map can identify how dietary diversity, supported by the conservation and sustainable use of crop diversity, can improve health, create economic opportunities, and enhance climate resilience.
The event will also mark the one-year anniversary of the initiation of the Global Conservation Consortium for Food Plants (GCCFP), which brings together botanic gardens, genebanks, and related sectors around the world to jointly ensure the safeguarding, sharing, and use of crop diversity. It will also highlight new data and insights from the Periodic Table of Food Initiative (PTFI).
Crop Diversity Day 2026 will connect the conservation of crop diversity with pressing global priorities, including nutrition, health, and climate action. Held during Climate Week NYC, the event will contribute to global dialogue on food systems transformation while elevating the role of crop diversity as a foundation for a healthier and more resilient future.
