                         degradation are increasing, and these issues are far from being 
                         independent of bioenergy production. The competing need for land 
                         and water resources in food and bioenergy production have been at 
                         the forefront of policy debates. In this study, we examined policy 
                         debates related to land, food and water use in sugarcane ethanol 
                         production, and the challenges to integrated landwaterenergy-food 
                         policies. We analyzed large amounts of data obtained from 
                         governmental and business documents, Brazilian newspapers, and the 
                         bulletins of non-governmental organizations over the last ten 
                         years by combining an unsupervised probabilistic latent Dirichlet 
                         allocation (LDA) model with sentiment analysis. The results show 
                         that land, energy and water are managed in isolation by separate 
                         and disconnected institutional entities. Although the discourses 
                         of actors have evolved over time in response to certain events 
                         (e.g., expansion of sugarcane and water scarcity), the discussions 
                         and resultant public policies have failed to consider the 
                         interdependence among various sectors. To achieve sustainable 
                         resource use, sugarcane ethanol expansion should be considered by 
                         decision-makers and companies within a wider governance framework 
                         based on nexus dynamics; specifically, trade-offs in land and 
                         water use with sectors beyond bioenergy must be acknowledged.",
