Conferences
19–24 October 2025, Punta Arenas, Chile
21st International Conference on Harmful Algae
The 21st edition of the International Conference on Harmful Algae (ICHA) will convene around 500 attendees from at least 50 countries, bringing together the world’s leading scientists and researchers addressing Harmful Algal Blooms (HABs). HABs represent a pressing global issue marked by a rise in frequency, scope, and impact. The increase in these events is attributed to several factors, such as nutrients increments in the water column due to human activities, ballast waters, advancements in science and technology geared towards studying these events, and extreme oceanographic climate fluctuations, such as El Niño and La Niña, the Antarctic Oscillation, as well as the broader effects of climate change.
The conference will be held in Chile, specifically at the Dreams Hotel in the city of Punta Arenas, from October 19 to 24, 2025. We extend a warm welcome and invite all of you to join and participate in this most important Scientific Conference on Harmful Algae, which will take place at the Southern tip of South America in Punta Arenas, Chile, amidst the breathtaking landscapes of Chilean Patagonia.
