The CNH Program supports basic research and related activities that enhance fundamental understanding of the complex interactions within and among natural and human systems. CNH seeks to advance basic knowledge about the system dynamics -- the processes through which systems function and interact with other systems. CNH-supported projects must examine relevant natural AND human systems. Proposals cannot focus solely or largely on either human systems or on natural systems. Projects also must examine the full range of coupled interactions and feedbacks among relevant systems.

Through its annual competition, CNH intends to make awards across a range of sizes from roughly $500,000 to no more than $1,500,000. Budgets should be developed at scales appropriate for the project to be conducted.
