Categorical principal component of current land cover, and art variables of the ‘future’ environment.

<p>The figure shows the relationships between the current land cover (black short line) of the villages (black dots) and the art variables from drawings (green triangles; see <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0103005#pone-0103005-t002" target="_blank">Table 2</a> for their names and codes) describing the children's perceptions of environmental conditions for the future, in 15 years’ time. The two first components explain 86.8% of the variability of the data (respectively, component 1: 72.0% and component 2: 14.7%). The villages fall into three broad groups (Group 1: high values on axis 1, consisting of villages 15, 16, 17, 12, 18, 19, 20 and 21, 22; Group 2: low values on axis 1, consisting of villages 2, 3, 9, 11, 13 and 14; Group 3: low values on axis 2, consisting of villages 1, 4, 5, 6, 7, 8, and 10. The art variable ‘People clearing the forest’ was high for all villages, and thus has no variance across villages and was not included in the PCA.
