Deep dives
The agricultural land usage topic was the clearest expression of Bahan’s geographic eye. Food appeared not as a lifestyle category, but as a spatial system: counties, commodity flows, factory fish, food miles, land-use conflict, and the uneven geography of abundance and scarcity.

The strongest thread connected industrial farming to the classroom. Tilapia, orange juice, GMOs, Vermont’s conflict with Monsanto, and the question of scale in farming all became case material for asking how production systems shape landscapes and choices.

He also reached beyond the United States. Global agriculture, women in farming, nomadic land use, and food security placed AP Human Geography concepts inside a wider world of labor, technology, culture, and risk.
Global State of Agriculture
The population and migration topic treated demography as something students could see and test. Refugee routes, immigration origins, population pyramids, mortality patterns, and pro-natalist policy were gathered as evidence for how people move, age, cluster, and confront borders.

Bahan favored resources that turned large patterns into readable visuals. A state-by-state map of immigrant origins, internal migration in Mexico, and world population data helped make demographic change less abstract and more spatial.

Policy mattered here, but the tone stayed analytical. Singapore’s pro-natalist policies, Mexico-U.S. migration shifts, and European border pressures were used less as talking points than as classroom cases for cause, consequence, and scale.

In political geography, Bahan built a teaching archive around borders as lived and contested lines. The topic moved from bruised boundaries and high-security borders to water disputes, sovereignty puzzles, and the ceremony of the India-Pakistan frontier.
Bruised Borders
The U.S. strand was especially classroom-ready. Apportionment, redistricting, census machinery, and interactive games made political power visible as a geographic process, not just a civics term.
The ReDistricting Game
The historical layer mattered too. Colonialism, imperialism, fragile states, and new countries appeared as reminders that political maps carry older struggles inside their present forms.
