Khalifa University of Science and Technology said on 24 September that 1,398 university students from 56 countries had registered for the Khalifa University–UNESCO Global Water Hackathon 2026. They are organised in 238 teams, including 266 students across 70 teams from the UAE. The university’s announcement describes registrations, not completed projects, selected finalists or solved water problems. The competition is designed to connect student teams with researchers, industry specialists and policymakers, then move selected ideas into a process of review and development.

The hackathon runs from 7 September to 10 December 2026, and the awards ceremony is scheduled to take place during the UN 2026 Water Conference in Abu Dhabi on 8–10 December. Khalifa University says the conference will be co-hosted by the UAE and Senegal. The competition is part of the university’s broader water research and youth-engagement work, including Youth4Water and the UNESCO Chair on Global Water Resilience, Innovation and Sustainable Solutions. The announcement says the hackathon contributes to preparations for the conference; it does not pre-announce conference outcomes or say that ideas from the competition will be adopted.

The university lists water security, desalination, water reuse and circularity, digital and artificial-intelligence-enabled systems, water quality and public health, environmental protection and climate resilience, and governance and cooperation within the competition’s six challenge areas. It describes these themes as aligned with UN water priorities. They span technical engineering, public health and institutional coordination. The announcement does not say that every team will work across every topic or that every proposal has already undergone technical validation. Registration figures demonstrate the competition’s international reach, but they do not yet measure the quality or feasibility of the solutions.

Selected teams are to move into a structured research phase with academic advisers, technical specialists and industry mentors. Khalifa University says this stage will include problem framing, validation and technical review, with the aim of turning early concepts into proposals that can be assessed against water challenges. Shadi W. Hasan, a university professor and chair of the hackathon, said the goal is to produce evidence-backed proposals that researchers, policymakers and industry can seriously assess. The source does not state how many teams will be selected, how much funding each project may receive or that prototypes will be deployed in the field. The research phase is a method for developing ideas, not a confirmed implementation or commercialisation decision.

Finalists will compete for the Khalifa University–UNESCO Water Innovation Award, six Best Theme Awards and three strategic-recognition awards covering UAE water priorities, climate and environmental resilience, and potential industry adoption. The university says finalists will be invited to Abu Dhabi to pitch their projects in person and attend the ceremony. Its announcement does not specify cash values for the awards. The 1,398 registrations and 238 teams describe a large starting field; ahead of the conference, it remains to be seen which proposals will reach the final, pass technical review or lead to further research investment.
