Agricultural Geography

Agricultural geography is a branch of human geography that studies the spatial relationships that exist between humans and agriculture.

The landscape of the Konsen Plateau viewed from above looks like a lattice with crisscrossing lines of narrow strips of forest.

Three moments in a tumultuous year for farming north of St. Louis, MO, as seen in NASA-USGS Landsat 8 data. On the left is May 7, 2019, as heavy rains delayed planting for many farms. Sept 12, 2019, in the middle, shows bright green signifying growing vegetation, although with a fair amount of brown, bare fields. On the right, Oct. 14, 2019, the light brown indicates harvested fields while darker brown are fields that have not been seeded or fallow all summer. Credits: NASA

Monitoring Crop Production Via Satellite

To cope with ever-changing agricultural needs and conditions, the USDA’s National Agricultural Statistics Service (or NASS) uses data from Landsat to monitor crops in the contiguous United States.

Satellite Data Shows That Tilling Less Leads to Healthier Soils

Why Development Aid Projects Must First Factor Local Culture

Devon Reeser

Why do some multi-million dollar aid projects fail? The aid itself is not generally the problem, but the lack of local, geographic specific cultural analysis in planning and implementation is most often to blame.
