The International Grassland Congress (IGC) is a worldwide gathering of leading scientists, students, industry, extension and primary producers that meet every 3-5 years to share their research results and their experiences.

From its beginning as a small group of researchers in Europe in 1927, it is now a gathering with over 1000 delegates from 80+ countries. Congress delegates often state that the IGC Congresses they attended were a highlight of their career because they interacted with people from around the world with a shared interest and passion for grasslands and the animals that grasslands sustain.

The International Grassland Congresses have spanned the globe and have been held on every continent with the last five in Brazil, Ireland, China, Australia, and India and upcoming Congresses in Kenya and the United States. Topics at these Congresses range from grassland production and utilization to grassland policies and social issues. Other topics include livestock production systems, grassland ecology, grassland sustainability, wildlife habitat, and ecosystem services. The impact of IGC Congresses extends long after the actual gathering of people with initiatives such as a study being commissioned on the global future of grasslands.
