Título: Percepção das mulheres em uma comunidade indígena no equador frente aos efeitos econômicos e emocionais da migração de familiares Autor(es): Macías, Jahayra Yamel Ayala Primeiro Orientador: Binotto, Erlaine Abstract: International migration has become a recurring subsistence strategy for many families, generating significant transformations both in the economic organization of households and in the emotional dynamics of those who remain in the community. The general objective of this research is to analyze women’s perceptions of the economic and emotional effects resulting from the migration of their family members. The specific objectives are: to analyze women’s perceptions of family economic dynamics in the context of family migration and the inflow of remittances; and to describe the emotional effects of migration from the women’s perspective. The research adopts a qualitative approach of a descriptive and analytical nature. Data were collected through semi-structured interviews conducted with a sample of 20 women whose family members migrated abroad. This study was carried out in a rural community in Ecuador, whose identity is not disclosed for ethical reasons. The information obtained was processed through categorical thematic analysis with the support of ATLAS.ti software. The economic results indicate that remittances mainly function as a survival fund used to cover basic needs such as food and education, rather than as capital for productive investment. A critical cycle of initial indebtedness was also identified, as many families must repay loans taken out to finance the migration process, which absorbs a large portion of remittances and delays improvements in family well-being. In addition, the results reveal the abandonment of local agricultural activities and the progressive aging of the rural workforce. At the emotional level, the findings reveal the persistence of migratory grief, often manifested through physical symptoms. Women also face a significant physical and emotional burden as they simultaneously assume the roles of both “father and mother,” managing the household under constant uncertainty regarding the well-being of the migrant. The results indicate that monetary inflows do not compensate for the suffering resulting from the rupture of family bonds. The findings also contributed new analytical properties. In the economic dimension, these include the failure of the migratory project, health-related expenditures, and the persistence of family indebtedness. In the emotional dimension, a constant concern about the risks faced by migrants emerged. By making these silent transformations in rural communities visible, this study contributes to understanding the multidimensional impacts of migration and aligns with the Sustainable Development Goals (SDGs) 1, 3, 5, 8, and 10, which address the eradication of poverty, health and well-being, gender equality, decent work and economic growth, and the reduction of inequalities, respectively.

Título: Vulnerabilidade social e políticas públicas de apoio à agricultura familiar: análise nas regiões brasileiras entre 2012 e 2021 Autor(es): Oliveira, Givago Almeida de Primeiro Orientador: Bungenstab, Davi José Abstract: Social vulnerability comprises a set of physical, financial, and human factors considered insufficient or inadequate for the quality of life of individuals or groups within a society. When associated with public policies supporting family farming, structural and regional differences become evident, particularly in the allocation of resources and the target population served. Thus, this study aims to analyze the relationship between the Food Acquisition Program (PAA), the National School Feeding Program (PNAE), the National Program for Strengthening Family Farming (PRONAF), and the Fomento Rural Program on the Social Vulnerability Index (SVI) across the five Brazilian regions between 2012 and 2021. A quantitative approach is adopted through the application of a panel data statistical model with random effects, in which the social vulnerability rate is used as the dependent variable, and the average financial transfers from the aforementioned programs as explanatory variables. The results confirm the central hypothesis that, for each of the four public policies, at least one of the five Brazilian regions presents average transfers with a statistically significant relationship with the SVI during the analyzed period. Specifically, PRONAF showed a highly significant and negative relationship in the Midwest; PAA indicated positive relationships, with moderate significance in the Northeast and low significance in the Midwest; food products acquired from family farming under PNAE showed a highly significant and negative relationship in the Northeast and Southeast; and Fomento Rural presented negative relationships with high significance in the North and moderate significance in the South. Overall, the findings indicate that the effectiveness of family farming programs depends not only on the volume of resources allocated but also on their integration and alignment with regional realities in terms of credit provision, technical assistance, and public procurement. These factors are crucial for the social inclusion of vulnerable producers and for promoting sustainable rural development in Brazil.

Título: Riscos climáticos e valor de mercado das empresas do agronegócio Autor(es): Garcia, Lorrana Damaris Soares Primeiro Orientador: Hoeckel , Paulo Henrique de Oliveira Abstract: This dissertation sought to analyze the relationship between climate risks and the market value of agribusiness companies. The study is divided in two articles: the first evaluates how the market value of Brazilian agribusiness companies is associated with climate risks; the second analyzes the relationship between climate risks and the market value of agribusiness companies worldwide, that is, how investors have reacted to climate risks both from the perspective of climate risk management and the exposure of companies to climate risks, divided in physical and transition. The research used the econometric model of panel data, using variables from LSEG Data & Analytics database. The first article analyzed climate risk from the perspective of climate management, through a variable that measures the efforts of companies to reduce carbon emissions. The analysis covered the period from 2019 to 2022, its results suggest that greater efforts by Brazilian companies to reduce climate risks, through their management, is negatively associated with their market value. In addition, it cannot be said that the agribusiness sector presents a different behavior from other companies in the Brazilian market. The same variable was used in the second article, in the period from 2021 to 2023, to analyze the perspective of climate risk management for agribusiness companies worldwide, the results indicate that agribusiness companies that adopt the practice of climate risk management have a reduced market value, however, when compared to other sectors it’s possible to observe an appreciation in the market, it was indicate a positive effect on the investor. For the second perspective, proxy variables present in the database were used, which indicate the exposure of companies to physical and transition risks. The main results indicate that agribusiness companies, when exposed to physical and transition risks, have lower returns on average compared to other sectors, reflecting greater sensitivity of the sector to these types of risks. For investors, this exposure may be associated with greater uncertainties in achieving returns, making the sector relatively riskier in these scenarios. The survey sough to highlight the importance of transparency in sustainability information, especially on climate risks, in the face of glowing demands from investors and international pressure for sustainable agribusiness. The work was intended to contribute with empirical evidence that is still little explored and to more sustainable practices in the agribusiness sector, aligning with the Sustainable Development Goals (SDGs) and promoting responsible and resilient production to climate change.

Título: Bioinseticida como alternativa sustentável e econômica Autor(es): Koch, Cláudio César Primeiro Orientador: Mauad, Juliana Rosa Carrijo Abstract: The increasing concern regarding food quality and the intensive use of pesticides, especially in vegetable crops, has stimulated research on bioinsecticides as an alternative to synthetic insecticides. Neem (Azadirachta indica) is recognized for its insecticidal effects. For smallholder farmers, who often produce primarily for subsistence, the on-farm production of extracts from neem leaves emerges as a viable alternative, given the limited availability of seeds for oil extraction. The present study aimed to evaluate the performance and feasibility of using aqueous and ethanolic extracts of neem leaves for the control of pests in collard greens under field conditions. The experiment was conducted between June 1, 2024, and October 10, 2024, in a completely randomized design, with five replications and five treatments: commercial neem extract (CE), aqueous extract of fresh leaves (AFL), ethanolic extract of fresh leaves (EFL), aqueous extract of dried neem leaves (ADL), and control (CONT). Pest infestations were monitored weekly. Total and marketable yields were evaluated over seven harvests, using three classes: 1 – no damage; 2 – up to 5% leaf loss; and 3 – more than 5% leaf loss or compromised plant structure. Classes 1 and 2 were considered marketable. The commercial extract required a lower number of applications (17), compared to the prepared extracts (19). All extracts showed equivalent results among themselves and relative to the commercial product and were superior to the control treatment in the control of Plutella xylostella, leaf damage reduction, and marketable yield. In the feasibility analysis, the commercial extract showed better performance in terms of cost benefit ratio (1:41) and Net Present Value (US$ 38,428.95). Among the prepared extracts, EFL was the most viable in terms of cost–benefit ratio (1:28.05) and AFL in terms of Net Present Value, while ADL was the least attractive option. The results indicate that neem leaf extracts are effective in controlling Plutella xylostella in collard greens and represent a sustainable alternative, especially for smallholder farmers, as they combine technical efficiency and economic viability.
