Abstract
Since the late 20th century, there has been a social mobilization towards sustainable managementof fishing resources on the lower Amazon floodplain, relying on fishing agreements. Successfulimplementation of these agreements has demonstrated their efficacy in replenishing fish stocks infloodplain lakes. However, crafting and executing fishing agreements present significant challenges,requiring intricate negotiations and delineation of responsibilities, particularly among fishermen andenvironmental agencies. To support this decision-making process, we proposed the co-constructionof a serious game, named Pesca Viva, utilizing participatory modeling. The Lago Grande do Curuai(LGC) region was chosen as the study area due to its reliance on fishing as a primary livelihoodand the significant pressures from large-scale fishing and environmental degradation. In 2021,fieldwork began with the establishment of a focus group comprising LGC fishermen leaders andenvironmental agency representatives. So far, twelve workshops on the game have been held withthe focus group and fifteen workshops with local fishermen in their respective communities. Byconvening these stakeholders around a role-playing game supported by a model, their diverse pointof views and knowledge effectively deliberated, enhancing the decision-making process regardingtheir fishing agreements.
