Research workshops for energy, water and food in the US have been funded $1.2m (£0.7m).
The National Science Foundation (NSF) is investing in 17 projects in total.
The goal is to find new ways of understanding food, energy and water systems.
The workshops are intended to bring together researches from the natural sciences, physical sciences, social and behavioural sciences and computing and engineering industries.
Researchers will also study technologies that can create resource efficiencies, reduce waste and enhance reuse.
Roger Wakimoto, NSF Assistant Director for Geosciences, said: “Understanding interactions between humans and the environment represents a grand scientific challenge, especially in the case of the food-water-energy nexus.
“This scientific challenge also encompasses critical policy and management questions for our future, making it a national priority.”
