Negative (left) and positive (right) sentiments associated with the SDGs and targets mapped in the urban agriculture literature

The darker color bar depicts the frequency of the mapped texts with positive or negative sentiments, considering more than two words associated with these sentiments (see experimental procedures for details). The light color bar represents the share of positive or negative sentiments among the targets within an SDG. It consists of the targets, e.g., 1.1, 1.2, and 1.3, with a share higher than 5%. Table S3 provides the full names of SDGs and targets.
