As the world’s population sprints toward larger and larger numbers, concerns about water scarcity follow closely behind. There are already disproportionate levels of water to need — especially in regions where infrastructure is lacking and rainfall over land cannot satisfy the local demand.

This past December, the second annual MIT Water Summit, organized by the MIT Water Club and directed by member Adam Weiner, a master’s-degree student in mechanical engineering, brought more than 200 students, faculty, business leaders, technologists, and investors together on MIT’s campus to discuss global water challenges and possible solutions. The two-day event was sponsored by the Abdul Latif Jameel World Water and Food Security Lab, directed by Professor John Lienhard.
