What Drives Intensification of Land Use at Agricultural Frontiers in the Brazilian Amazon? Evidence from a Decision Game by Nascimento, N., West, T.A.P., Börner, J., Ometto, J.

“…Here, we use a scenario-based decision game to examine hypothetical land-use decisions among four groups of rural producers in the municipalities of Sinop, Guarantã do Norte and Novo Progresso in the Brazilian Amazon. We simulate changes in agricultural prices, production cost, and frequency of environmental monitoring (in situ inspections) to understand how land-use decisions are made and change with shifts in economic and governance incentives. …”

Understanding Difference to Build Bridges among Stakeholders: Perceptions of Participation in Four Multi-stakeholder Forums in the Peruvian Amazon by Sarmiento Barletti, J.P., Larson, A.M., Heise Vigil, N.

“…In order to better understand these nuances, the authors applied Q-methodology to analyse and compare the perceptions of MSF participants and organisers in four forums in the Peruvian Amazon. The research finds that participants are often optimistic about the forums, but at the same time they are aware of risks; and that groups falling into both camps may be just as likely to fail to address inequality among participants but for different reasons. …”
