Serious Games

Serious games are interactive learning tools designed to build knowledge, strengthen problem-solving skills, and support collaboration through play. By placing participants in realistic scenarios, they help translate complex environmental challenges into practical decisions, trade-offs, and solutions. As part of the Clean and Healthy Ocean Integrated Program (CHO-IP), serious games are used to engage partners, practitioners, and learners on nutrient pollution, marine hypoxia, and source-to-sea action in an accessible and participatory way.

O₂No!: Learning about marine hypoxia through teamwork and creativity

O₂No! is a fast-paced card game that raises awareness of nutrient pollution and marine hypoxia, also known as low-oxygen conditions that can create coastal “dead zones.” Players answer, draw, or act out concepts related to ocean geography, the causes and impacts of hypoxia, and practical solutions to reduce nutrient runoff. By combining quiz-based learning with creativity and teamwork, the game helps participants better understand how actions on land influence ocean health and how improved nutrient management can generate global environmental benefits.

Dead Zone: Exploring source-to-sea solutions through strategy

Dead Zone is a strategy-based simulation in which players manage nutrient flows across a watershed to prevent coastal pollution and ocean deoxygenation. Participants take on the role of decision-makers, balancing agricultural, municipal, industrial, fisheries, and aquaculture development with investments in pollution-reduction measures. Through pollution cards, solution cards, and governance special cards, the game encourages systems thinking, integrated coastal planning, and collaboration, while showcasing good management practices such as nature-based solutions, wastewater treatment, cleaner production, water quality monitoring, and women-led actions.
