| Shifting cultivation systems, one of the most widely distributed forms of agriculture in the tropics, provide not only crops of cultural significance, but also medicinal, edible, ritual, fuel, and forage resources, which contribute to the livelihoods, health, and cultural identity of local people. In many regions across the globe, shifting cultivation systems are undergoing important changes, one of the most pervasive being a shortening of the fallow cycle. Although there has been much attention drawn to declines in crop yields in conjunction with reductions in fallow times, little if any research has focused on the dynamics of noncrop plant resources. In this paper, we use a data set of 26 fields of the same age, i.e., ~1.5 yr, but differing in the... |

| Economic Experimental Games (EEGs), focused to analyze dilemmas associated with the use of common pool resources, have shown that individuals make extraction decisions that deviate from the suboptimal Nash equilibrium. However, few studies have analyzed whether these deviations towards the social optimum are affected as the stock of resource changes. Performing EEG with local fishermen, we test the hypothesis that the behavior of participants differs under a situation of abundance versus one of scarcity. Our findings show that under a situation of scarcity, players over-extract a given resource, and thus make decisions above the Nash equilibrium; in doing so, they obtain less profit, mine the others-regarding interest, and exacerbate the tragedy of the... |
