Hypothesis

To what extent does the spatial distribution of socioeconomic conditions explain coca cultivation patterns in the state of Nariño?

Conclusion

The study found that areas with high poverty and low education levels have a higher concentration of coca cultivation, indicating a need for targeted public policies.

Supporting Evidence

  • The Gini index in Colombia was 0.556 in 2022, indicating high inequality.
  • Nariño accounts for 65% of Colombia's cocaine production.
  • The study constructed composite indices for education, health, public services, and economic conditions.

Takeaway

In Nariño, Colombia, places with less education and more poverty grow more coca plants, so helping these communities could reduce coca farming.

Methodology

The study used spatial analysis and econometric models to examine the relationship between socioeconomic indices and coca cultivation across 64 municipalities.

Potential Biases

Potential biases may arise from using data collected in different years.

Limitations

The study lacked detailed local data on social capital and armed group activity, which could enrich the analysis.

Participant Demographics
