Ask HN: Ideas for 24 hour Hackathon at college

Hello, I'm an undergrad in Computer Science, and our college is conducting a Hackathon based on the theme Computing for Society. We have been given the problem statements from the UNSDG link - https://www.un.org/sustainabledevelopment/sustainable-development-goals/ which comprises of various problems faced by society and we need to develop solutions to tackle these problems from a Computer Science perspective in 24 hours, like making an app which can track the vaccination details for a child. Please comment on any ideas or anything which will be helpful. Thank you.
