ABSTRACT
This chapter outlines levels of analysis and fairness-related justice concepts, before it discusses consequences of applying these to the topic in question and considers major contributions of psychology to explain social systems' functioning under global change. Focusing intrapersonal, interpersonal and intergroup processes, research on fairness-related aspects is well established in social psychology. Social psychology consequently introduced a further level of analysis by studying dyads - primarily close relationships, but also larger social units in natural contexts or artificial configurations in laboratory settings. As increasingly confirmed, psychology accepts the challenge and applies state-of-the-art concepts in order to contribute to global change research. Temporal as well as geographic scales exploded: global circulation models indicated that long-term calculations must be introduced when global processes are under consideration. Meanwhile it is a self-evident position of global change research that humans are causing, as well as are affected by, global and regional environmental changes.
