What the study found

People are mostly staying within northwest Argentina but moving toward emerging cities in valleys, departments, and province capitals. At the local level, mountainous land that is unsuitable for agriculture is being abandoned, while populated centers and valley areas with suitable land for agriculture are growing.

Why the authors say this matters

The authors suggest that emerging cities are becoming new hotspots, keeping population within the region while contributing to the abandonment of marginal mountainous areas. They conclude that these demographic shifts may be linked to different patterns of land use deintensification and intensification.

What the researchers tested

The study used data from the National Population Census and National Agricultural Census. The researchers examined migratory movements within and outside the High Monte of northwest Argentina, changes in livestock numbers and crop production area, and local-scale population changes across areas with different population density and cultivated area.

What worked and what didn't

Livestock numbers decreased in most departments. Cultivated area decreased in half of the departments and increased in the other half. The study also found that people tended to remain within northwest Argentina while moving toward urban centers, and that mountainous areas with less suitable agricultural land were being abandoned.

What to keep in mind

The abstract does not describe detailed limitations beyond the regional and local scope of the data used. The findings are specific to the High Monte of northwest Argentina and the census-based measures reported in the study.

Key points

  • Most migration stayed within northwest Argentina, with movement toward emerging cities and province capitals.
  • Mountainous areas unsuitable for agriculture were being abandoned at the local scale.
  • Population centers and valley areas with suitable agricultural land were growing.
  • Livestock numbers decreased in most departments.
  • Cultivated area decreased in half of the departments and increased in the other half.
