Educação ambiental como instrumento de ensino sobre mudanças climáticas por meio de jogos ambientais
(Universidade Federal de São Carlos, 2025-11-24) Pimenta, Daniela; Neves, Anne Alessandra Cardoso; http://lattes.cnpq.br/5825341428803511
The present study consisted in practical analysis of the use by educational games as a tool for environmental education. The research was carried out with fourth-grade students from the municipal school system in Votorantim/SP. For this purpose, an environmental game on climate change was developed, addressing topics such as greenhouse effect, causes and consequences of climate change, and possible mitigation strategies. In addition to playful activity, the students answered a written questionnaire, allowing for evaluation of their understanding about topics presented. The results showed significant improvements in learning, confirming the effectiveness of educational games as a resource to promote awareness and the development of values related to sustainability and fight against climate change.
Estratégias do Banco Mundial para a mitigação das mudanças climáticas no setor agropecuário do estado de São Paulo: uma análise dos programas Microbacias I e II
(Universidade Federal de São Carlos, 2025-11-19) Pereira, Giovanna Victória Aguiar; Borsatto, Ricardo Serra; http://lattes.cnpq.br/5988987575101933; https://orcid.org/0000-0002-7594-479X
This study aims to analyze the World Bank’s strategies for mitigating climate change in the agricultural sector of São Paulo State, using the Watershed Programs I and II as case studies. The objective is to understand whether these programs were effective not only from an economic perspective but also regarding environmental sustainability and the capacity for adaptation to climate change. The research adopts a qualitative and quantitative approach, based on an integrative systematic literature review focusing on studies, theses, and articles that evaluated the outcomes of these programs in different regions of São Paulo. The results showed that the Watershed Program I was essential for strengthening family farming and conserving natural resources, standing out for encouraging the adoption of sustainable practices, environmental restoration, and improvements in rural infrastructure. The Watershed Program II, although advancing in the strengthening of cooperatives and associations and promoting the market integration of family farmers, presented weaknesses in social inclusion and environmental integration. The discontinuity between the two phases generated distrust and reduced the long-term positive impacts of public policies. It is concluded that the Watershed Programs represent significant experiences of sustainable rural development in São Paulo State, but they require greater institutional coordination, administrative continuity, and producer participation to consolidate themselves as effective instruments for climate change mitigation and adaptation.
Planejamento de roteiros ecoturísticos na Floresta Nacional de Capão Bonito (SP)
(Universidade Federal de São Carlos, 2025-09-09) Santos, Mariane Thaís; Beisiegel, Beatriz de Mello; http://lattes.cnpq.br/8143797535693714; https://orcid.org/0000-0001-5297-4390; Lobo, Heros Augusto Santos; http://lattes.cnpq.br/9405961078398915; https://orcid.org/0000-0001-6994-0138; http://lattes.cnpq.br/7263067635074048; https://orcid.org/0009-0000-1446-8331; Raimundo, Sidnei; Leite, Eliana Cardoso; http://lattes.cnpq.br/0352060547192132; http://lattes.cnpq.br/2186623269243747; https://orcid.org/0000-0002-2182-9593; https://orcid.org/0000-0003-3152-2576
This study focuses on public use (PU) and ecotourism in the Capão Bonito Forest (FLONA), with a particular emphasis on planning ecotourism itineraries for the Visitation, Interpretation, and Environmental Education Program in the Conservation Unit (UC). The UC is located in the state of São Paulo (SP) and covers the municipalities of Buri and Capão Bonito. Located in an area of high ecological and sociocultural importance, the study aimed to evaluate potential itineraries and attractions that could contribute to the UC's visitation program. The study sought to diversify ecotourism practices by considering different visitor profiles and demands. Ten itineraries were evaluated based on the attributes and indicators of the List of Visitation Opportunities in Conservation Units (ROVUC) and were classified according to the experience classes suggested by the ROVUC. In conclusion, FLONA has high ecotourism potential, offering diverse experiences aligned with the management zones. A Public Use Plan should be developed to regulate public visitation and integrate conservation, education, and local development.
Análise do impacto idiossincrático do caso Americanas em fundos de investimento em renda fixa de crédito privado no Brasil
(Universidade Federal de São Carlos, 2025-12-03) Cazetta, Felipe Faria; Montoril, Michel Helcias; http://lattes.cnpq.br/9993502064983663; https://orcid.org/0000-0001-8431-3087; http://lattes.cnpq.br/0099270096028828; https://orcid.org/0000-0003-1645-1001
This study evaluates the idiosyncratic impact of the Americanas case, materialized in the material fact disclosed on January 11, 2023, on Brazilian fixed-income private credit investment funds over the period from 2022 to 2024. The event study methodology is employed, constructing abnormal returns (AR) by adjusting fund returns to the CDI, used as the benchmark, and their aggregations into average abnormal returns (AAR) and cumulative average abnormal returns (CAAR) over the [-20, +60] window for two groups, top 10 and bottom 10, ranked by net asset value as of the last day of the sample. To test for a regime shift, mean ARs in the pre- [-60,-1] and post-event [+1, +60] windows are compared using Welch’s t-test. The results reveal an immediate negative shock in AR, with a statistically significant average drop for the top 10 group (p <0.01) and borderline statistical evidence for the bottom 10 group (p ≈ 0.056). The top 10 funds exhibit lower volatility, a shallower drawdown, better risk metrics, and more resilient f lows, suggesting that scale and diversification mitigate losses and speed up post-shock recovery. Limitations and possible extensions are discussed, such as the incorporation of additional events, strengthening the robustness of the sample, and using alternative reference indices. Finally, the results provide insights for investors, asset managers, and regulators, reinforcing the importance of sound mark-to-market practices, liquidity management, and governance.
Modelagem do processo de eutrofização em um reservatório de clima tropical

This study proposes the development of a new Trophic State Index (TSI) model for tropical environments, using the Tucuruí Hydroelectric Power Plant reservoir as a reference point, based on 14 years of data (2003–2016). To provide analytical validation of these results, two sampling campaigns were conducted during the rainy and dry seasons (March 2022 and October 2023). The Mann–Whitney test was applied to five sampling stations using as variables: total phosphorus, total pigments, and water transparency, along with the TSI defined by Lamparelli, to assess its effectiveness in determining the trophic status of the reservoir. Statistical analyses were performed at eight sampling stations distributed across all areas of the reservoir. Analyses covered both rainy and dry seasons and included the Shapiro–Wilk test for normality; Student’s t-test for normally distributed variables; and the Mann–Whitney test for non-normal variables. Relationships between variables were evaluated using simple linear regression with logarithmic transformation, and homoscedasticity and independence of residuals were assessed using the Breusch–Pagan and Durbin–Watson tests. A 5% significance level was adopted. Ordinary Kriging was also employed for spatial interpolation. The results of the analytical validation indicated that the medians and ranges observed in the samples collected in 2022 and 2023 fall within historical limits for all variables analyzed. A new TSI’ was developed, better suited to the reservoir’s conditions through the use of magnesium and total pigments as key variables. Ordinary Kriging enabled effective interpolation of the new index, confirming—across different seasonal periods—an appropriate trophic classification of the reservoir.
