UNESCO’s Youth Water Challenge 2025 spotlights innovative, interdisciplinary solutions to pressing water issues in Viet Nam, led by young innovators under the age of 30. Water remains fundamental to life and a key pillar of sustainable development, yet UNESCO’s 2025 World Water Development Report highlights that nearly 4 billion people worldwide face severe water scarcity at least part of the year. In Viet Nam, the combined pressures of climate change, urbanization, and environmental degradation have intensified the need for effective water management strategies.
In response, UNESCO Viet Nam, in partnership with the Institute for Innovation and Development (IID), launched the Youth Water Challenge to identify and support breakthrough ideas addressing water challenges and promoting Sustainable Development Goal 6, which ensures clean water and sanitation for all. The competition attracted nearly 100 proposals from young people across the country, covering a wide range of topics including intelligent water management systems, pollution treatment technologies, nature-based adaptation, and innovative approaches to improving water access. Ten standout initiatives were selected to present at the Pitching Day held on 15 August in Hanoi.
The top three projects illustrate the diversity and potential of youth-led innovation in Viet Nam. One team proposed a solar-powered desalination system to provide freshwater for remote islands and offshore communities. Another developed an advanced filtration membrane capable of removing harmful nitrogen compounds from household water in rural areas. A third initiative designed a community-scale wetland system that transforms domestic wastewater into an educational and ecological resource, fostering engagement among students and local communities.
The participating teams emphasized the critical role of young people in driving systemic change. They highlighted that youth bring energy, creativity, and access to cutting-edge technologies, but successful innovation also requires ethics, discipline, and purpose to ensure solutions truly benefit people. These insights underline the transformative potential of youth in shaping long-term, practical water solutions.
Science, technology, and innovation are central to Viet Nam’s national strategies on digital transformation, climate adaptation, and green growth. While young people have the creativity, digital skills, and global networks to advance these goals, converting ideas into real-world impact requires supportive ecosystems that provide funding, expert mentorship, and opportunities for field testing.
As the UN’s lead agency for water science and education, UNESCO works with Member States to build such ecosystems. Its Intergovernmental Hydrological Programme (IHP), celebrating 50 years in 2025, remains the only intergovernmental initiative dedicated to water science, management, and education. The Youth Water Challenge 2025 exemplifies UNESCO’s commitment to linking youth-led innovation with policy and action, advancing SDG 6 through scalable, local, and interdisciplinary solutions.
