| Research Abstract |
Cooperation is a key to maintain ecosystem as commons. However, people do not always cooperate because of the cost of cooperation. Punishment to non-cooperators is said to promote cooperation, but punishment is also costly. Here we investigated how people punish others according to others' cooperation level by evolutionary simulations. I also investigated the evolutionary condition that cooperation is sustainable when people invest their efforts to commons simultaneously and one of then can receive a benefit from commons by rotation by evolutionary simulations.
Terrace rice fields in Japan should be sustainable as Japan's cultural heritages and I decided to make a mathematical and simulation model to investigate what kinds rules and customs maintain terrace rice fields. It is still an ongoing work and I will show you what makes terrace rice field sustainable in a future topic.
