From: Farm typology of smallholders integrated farming systems in Southern Coastal Plains of Kerala, India
Spatial distribution of four farm types resulting from principle component analysis and cluster analysis on the planes defined by first three principle components: Circles of correlation (A, B) and clustered farm households viz., farm types 1–4 (C, D) projected on the planes PC1–PC2 and PC1–PC3. The variables highlighted in red correlate strongly with PC1 and are the most explanatory variables of the horizontal axis (PC1); those variables highlighted in blue correlate strongly with PC2 and PC3 and are the most explanatory variables of vertical axes (PC2 and PC3), thus defining the gradients.
