Global Change · Local Impact

Aloha and welcome to the Department of Geography and Environment at the University of Hawai‘i at Mānoa! Geography is a diverse discipline that is united by its focus on global change and local impacts on humans and the environment. The department was founded in 1932 and is consistently ranked among the top programs in the US. Faculty have expertise across the breadth of the discipline in environmental geography, human geography, and geospatial information science, with a focus on Asia and the Pacific. Our BA, MA, and PhD students research topics such as environmental change, sustainability, and globalization and have gone on to careers in academia, government service, NGOs, and in the private sector.

The World Health Organisation’s latest figures show that across the world, there are close to 1.5 billion people – about one fifth of the world’s population – infected with parasitic worms.
