Experimental games help communities explore solutions

2019 
The results of our games show that farmers act less selfish than theory predicts. Nevertheless, even in the presence of transparent decisions and repeated possibilities to discuss, groups manage to produce enough water for everyone to grow crops only in approximately 50% of the played rounds. The red line in Figure 3 indicates the social optimal investment level in our game. At this level, all players of a particular group could grow the water-efficient rabi (postrainy) crop (chickpea). Still, in 15% of the crop decisions in the game, players decided to grow the waterintensive crop (wheat). It was very transparent in the design of our game that this was an uncooperative action.
