Agrupamiento Espacial de Emisiones de Metano por Ganado Vacuno en Pastoreo en México

Summary

A spatial-clustering analysis of methane emissions from grazing cattle in Mexico using station and state data for June 2024. It compares Queen contiguity and centroid-distance \(k=4\) weights with Max-p and Spatially Constrained K-Means, evaluating cluster quality through the between-to-total variability ratio \(BSS/TSS\).

Context

The study aggregates measurements from 2,305 monitoring stations by Mexican state and uses a national equal-area reference system to examine spatially constrained groups.

Main contributions

• Compares spatial weights based on Queen contiguity and Euclidean distance between state centroids with (k=4) nearest neighbours.
• Evaluates Max-p and Spatially Constrained K-Means clustering for methane-emission patterns.
• Uses the (BSS/TSS) ratio to compare between-cluster and total variability.
