Table 1 Predicted FoI averaged across all Colombian municipalities in 1980, 1990 and 2010, the percentage of decrease between 1980 and 2010 (trend) for each setting and the spatial clustering effect given by the Moran’s I statistic for the test under randomisation in 1980, 1990, 2000 and 2010 (n = 1065 municipalities)
