Abstract: Coffee is one of the most traded commodities in the international market, with prominence to the production of specialty coffees. Within this context, coffee in the state of Ceará is particularly relevant for its high quality, as the Baturité Massif regionaccounts for 70% of the state's income, generating employment and local income. The objective is to analyze the profitability of shaded coffee producers in the Baturité Massif, state of Ceará, under deterministic and risk conditions in 2023. The analysis methods are: the analysis of profitability indicators based on parameters of gross income and production costs, and the risk analysis by the Monte Carlo method to estimate the probabilistic distribution of each profitability indicator. The results showed that production has a positive average gross margin, allowing producers to remain in the activity in the short term. The risk analysis showed low risk, and this production is very profitable, as there is a 94% probability that the profit will be higher thanthe sample average.

Abstract: This study investigates synergies between Agroamigo resources and the performance of rain- fed agriculture in the Semi-Arid Region, focusing on rice, beans, cassava, and corn crops, which are predominant in the region and sensitive to climatic variations. The states of Bahia, Ceará, Maranhão, Pernambuco, and Piauí are evaluated, as they account for the largest number of
operations and resources in 2024 within the BNB’s area of operation. The objectives of the research are: i) to evaluate territorial expansion, contract dynamics, and financial resources, as well as economic relevance; ii) to assess the relationships between variables that influence agricultural production; and iii) to compare the Productivity Index (INPR) and Aggregate Production Value per hectare (VPA) before and after the implementation of the Program. and
Experimental (2005–2024), the period following its implementation. The INPR and VPA are estimated to assess structural and productive changes associated with Agroamigo. The results show the program’s expansion, with the number of contracts increasing from approximately 18,000 to nearly 688,000 and total funding reaching approximately R$60 billion. However, real growth was limited compared to the minimum wage. Extensive coverage was observed in the
Semi-Arid region, along with interdependence among crops, influenced by structural and technological factors. The INPR demonstrated good explanatory power, particularly in Ceará, Pernambuco, and Maranhão. The impacts were mixed, with income gains in Ceará and productivity gains in Maranhão, but unfavorable results in the other states. The overall conclusion is that Agroamigo contributed to boosting the productivity of family farming in the
Semi-Arid region, although its effects depend on local structural and climatic conditions to translate these gains into increased income, as is expected in agricultural activities in general.

Abstract: The Matopiba region, composed of municipalities in Maranhão, Tocantins, Piauí, and Bahia, has undergone considerable and rapid transformations in land-use dynamics over recent decades, mainly due to the expansion of agricultural activities. Given the growth and importance of grain production for the Matopiba region and the way climate change can affect this production, as well as the important role of agriculture in mitigating these climate changes through the reduction of greenhouse gas (GHG) emissions, the present study is
necessary to evaluate the presence of convergence clubs with respect to GHG emissions originating from the agricultural sector in the Matopiba region. For this purpose, the methodology developed by Phillips and Sul (2007) was used, as it is suitable for this study because it allows the identification of dynamic patterns of behavior among spatial units over time, even when they present distinct initial trajectories. The three scenarios created for this research presented the same results: rejection of the null hypothesis of global convergence and the formation of one convergence club, with no municipality being considered divergent. This means that all municipalities follow the same general trend in the evolution of emissions over time, that is, the municipalities are homogeneous in terms of their emissions trajectory. One possible explanation for this result is the agricultural expansion that has been occurring in the region, causing the productive profile, environmental policies, good management practices, and technologies used to be disseminated throughout the region. Understanding that all municipalities in the Matopiba region belong to the same convergence club is very important for policymakers, since common factors across the entire region will exert the same relative influence on agricultural emissions.

Abstract: n this study we evaluated the relationship between economic growth and solid waste (SW) generation in Brazilian municipalities and, following fixed-effects panel data regressions, estimated the environmental Kuznets curve (EKC) of the dataset. The resulting curve did not exhibit an inverted U-shaped relationship, as expected. We also concluded that selective waste collection had a positive effect on SW management, but the effect was negative when the service was charged.
