The aim of this study was to analyze the production patterns present in rural properties producing cattle in the micro-regions that make up the state of Pará. Exploratory Factor Analysis (EFA) was applied to identify the patterns, and these data are used to evaluate correlation between the heterogeneity of rural properties and the environmental impact on the identified patterns. The theoretical contribution is based on discussions on global impacts of food production and environmental sustainability and the impacts of livestock production systems in Brazil and the Amazon. Survey data were taken from the 2017 Agricultural Census, available for the 144 municipalities in the state, and pooled into 22 micro-regions. Three patterns of rural properties were identified: the first related to conservation management practices and called transition management; the second highlights aspects associated with information technology and communication (ICT) and productivity called technical productive efficiency; the third indicates the importance of social organization and access to information called social participation. With these patterns, it was possible to develop the Traditional Performance Indicator (TPI), in which the micro-regions of São Félix do Xingu, Itaituba and Conceição do Araguaia were those with the highest values of this indicator, water protection practices are present in the properties, however, in precarious conditions, and conservation practices are rarely used. The correlation between heterogeneity, measured by the size of pasture area in each microregion, and the TPI is positive, strong and significant. In this transition context, public policies are essential to provide access to infrastructure, credit and good animal health and biotechnology practices

Abstract The Atlantic Niño is one of the most important tropical patterns of interannual climate variability, with major regional and global impacts. How global warming will influence the Atlantic Niño has been hardly explored, because of large climate model errors. We show for the first time that the state-of-the-art climate models robustly predict that equatorial Atlantic Niño variability will weaken in response to global warming. This is primarily because subsurface and surface temperature variations decouple as the upper equatorial Atlantic Ocean warms. The weakening is predicted by most (>80%) models following the highest emission scenarios in the Coupled Model Intercomparison Project Phases 5 and 6 considered here. These indicate a reduction in variability by the end of the century of 12-17%, and as much as 25% when accounting for model errors. Weaker Atlantic Niño variability will have major consequences for global climate and the skill of seasonal predictions.

Abstract. This work provides a hypothesis of the links between the multi-millennia scale recurrent solar and tidal influences and Earth's climate lagged responses, associated with the oceanic transport mechanisms with a variable modulation. As a part of this hypothesis, empirical and simple, non-linear lagged models are proposed for five of the most representative Earth's climate variables (a continental tropical temperature, an Antarctic temperature [at James Ross Island], the Greenland temperature, the global temperature and the southeast asian monsoon) with multi-millennia records to account for the lagged responses to solar forcing. The proposed models implicitely include a well-known oceanic heat transport mechanism: the Ocean Conveyor Belt. This oceanic mechanism appears to generate a climate modulation through the intensity of the ocean/atmosphere circulation, and a heat and mass transport, with a consequent climate lag of several thousands of years. Tidal forcing is also considered for global temperature modelling and forecast. The consequent millennia-scale global forecasts, after being integrated/verified with an accumulated ocean travelled distance from the tropical East Pacific, and with a double evaluation of the tidal influences based on similarities and on the NASA’s solar system astronomical dynamics, indicates a cooling for the next century, and gentle oscillations over the next millennia. Our preliminary results that strongly suggest that millennial scale changes in solar activity induce circulation and thermal global impacts, also suggest that the Younger Dryas event, may be influenced by the lagged outcomes of solar driven changes in the tropical Pacific, and by tidal influences. The detected Earth's climate delayed responses, that have been working in the past and present climates, and will be working in the future climates, must be, as soon as possible, independently verified and theoretically sustained, before to be fully included in a multi-scale climate models as a scientific theory. A final example for the global temperature record over the last 170 years demonstrates with experimental results for the twenty first century evolution the convenience of a multi-scale climate modelling with contrasting lower values compared with the IPCC global temperature scenarios.

When engaging stakeholders in environmental conservation, it is critical to understand not only their group-level needs, but also the individually held beliefs that contribute to each person’s decisions to endorse or reject policies. To this end, we examined the extent to which people conceptualize the interconnected relationship between humans and nature in the context of a hypothetical urban waterway, and the implications thereof for environmental investment and stewardship. We also explored how these beliefs varied based on describing the waterway as having either local or global impacts, and as originating either naturally or through artificial processes. Three hundred and seventy-nine adults from the United States read vignettes about a polluted urban waterway and thereafter reported their investment in river clean-up, their stewardship of the river, and their beliefs surrounding human-nature relationships. Results revealed a common belief pattern whereby humans were believed to impact the urban river disproportionately more than the river impacts humans, suggesting that lay adults often weigh the impacts of humans on the natural world disproportionally. Critically, this disproportionate pattern of thinking inversely predicted investment of time and money in river clean-up. Results also revealed a potential solution to this psychological bias: highlighting local benefits of the waterway decreased the asymmetry of the human-nature relationship. We discuss the psychological factors contributing to this cognitive bias, and the implications of these findings on stakeholder engagement.

Migration, participation, and citizenship, are central political and social concerns, are deeply affected by money. The role of money - tangible, intangible, conceptual, and as a policy tool - is understudied, overlooked, and analytically underdeveloped. For sending and receiving societies, migrants, their families, employers, NGOs, or private institutions, money defines the border, inclusion or exclusion, opportunity structures, and equality or the lack thereof. Through the analytical lens of money, the chapters in this book expose hidden and sometimes contradictory policy objectives, unwanted consequences, and inconsistent regulatory structures. The authors from a range of fields provide multiple perspectives on how money shapes decisions from all actors in migration trajectories, from micro to macro level. Taking an interdisciplinary approach, the book draws on case studies from Europe, the Americas, Asia, and Africa. This comprehensive overview brings to light the deep global impacts money has on migration and citizenship.
