NSF 25-507: Human-Environment and Geographical Sciences Program (HEGS)

Research Focus

The Human-Environment and Geographical Sciences Program (HEGS) supports fundamental research on the spatial dimensions of human behaviors, activities, and dynamics and their interactions with environmental and social processes across multiple scales. The program seeks empirically grounded, theoretically engaged, and methodologically rigorous work that advances geographical and geospatial sciences. Research must be generalizable and reproducible; proposals applying geographical or geospatial methods to a problem without proposing a theory-testing or theory-expanding contribution to geographical science will be returned without review. Successful projects should enhance fundamental geographical theory and geospatial methods while demonstrating broader societal benefits. The program emphasizes human dimensions relevant to people and societies and welcomes quantitative, qualitative, or mixed-methods approaches that address confounding variables and selection or confirmatory biases.
