Sustainable mobility in university environments presents both a challenge and an opportunity to reduce environmental impact and promote energy efficiency. This study assesses the feasibility of implementing electric buses in the internal transportation system of the Federal University of Paraíba (UFPB), considering environmental, economic, and operational aspects. The analysis demonstrates that transitioning to this model can lead to a significant reduction in greenhouse gas (GHG) emissions, noise pollution mitigation, and optimization of operational costs throughout the vehicle’s life cycle. The study examines technical, structural, and financial factors, emphasizing the necessary infrastructure, academic community acceptance, and the economic viability of the project, as well as the strategic advantage of integrating the electric fleet with photovoltaic energy generation. The key highlights of this research include: (i) Sustainability and energy efficiency, emphasizing a reduction of up to 52.52% in CO₂ emissions when vehicles are powered by photovoltaic energy in an LCA context, alongside improvements in air quality and noise pollution mitigation. (ii) Economic feasibility analysis, comparing operational and maintenance costs between electric and conventional diesel buses, evaluating the financial viability and potential return on investment. (iii) Infrastructure and implementation challenges, addressing the need for charging stations, adaptation of UFPB’s infrastructure, and financing models, including government subsidies and strategic partnerships. (iv) Impact on the academic community, analyzing student and staff perceptions and acceptance of fleet electrification and the promotion of sustainable practices. (v) Future projections and replicability, exploring trends in the sustainable transportation sector, as well as the potential expansion of the electric fleet and its integration with energy storage systems. The results indicate that adopting electric buses at UFPB can position the institution as a benchmark in sustainable mobility, serving as a replicable model for other universities and contributing to carbon emission reduction and modernization of university transportation.

O sul do Amazonas encontra-se em um ciclo de atividade de exploração intensa que tem avançado rapidamente e, devido a isso, seu microclima tem sido modificado. Todavia, a ocorrência de eventos climáticos, tal como o fenômeno oceânico de grande escala El Niño – Oscilação do Sul (ENOS), influenciam no comportamento do clima e principalmente na dinâmica da precipitação. Este trabalho teve como objetivo analisar a influência do El Niño, nas intensidades moderada e forte, na precipitação da mesorregião Sul do Amazonas. O estudo foi realizado através de análise de dados de precipitação, em sete anos com episódios de El Niño, para os municípios de Apuí, Boca do Acre, Humaitá e Lábrea. Os dados de precipitação foram obtidos pelo sensor TRMM_3B42RT do satélite Tropical Rainfall Measurement Mission. Os totais sazonais médios (períodos seco e chuvoso) e anuais dos anos de ocorrência do fenômeno foram comparados com as normais climatológicas de cada município. O município mais afetado pelo evento foi Lábrea, com influência em aproximadamente 71% do total de anos estudados. O menos afetado foi o município de Apuí, com apenas 43% do total de anos afetados. Por fim, evidencia-se que as maiores anomalias de precipitação ocorrem em anos de El Niño forte e que o evento afeta principalmente a estação chuvosa da região amazônica.

Impacts of El Niño – Southern Oscillation (ENSO) climatic phenomena in the southern mesoregion of the Amazon is still poorly understood. Thus, the objective of this study was to analyze the impacts of ENSO of moderate and strong categories on precipitation (ppt) and surface temperature (ts) in the southern mesoregion of Amazonas. The research was carried out with ppt data obtained by the product TRMM_3B43 and ts of the product MOD11C3 in the municipalities of Apuí, Boca do Acre, Canutama, Humaitá, Lábrea, Manicoré and Novo Aripuanã. The Niño Indices were obtained from the National Oceanic Atmospheric Administration. Ts was organized into averages and ppt in seasonal totals from 1998 to 2019, to obtain its provisional climatological normal in the dry and wet seasons. The results showed that ENSO significantly influenced the pattern of ppt and ts in the southern mesoregion of Amazonas. El Niño (EN) had more impact on changing the pattern of ppt and ts than La Niña (LN). The largest reductions in ppt and increases in Ts occurred in the EN periods of 1998/01 and 2015/16, while the occurrence of LN decreased the ppt more expressively in the periods of 2007/08 and 2011/12.

Objective: The aim of this research is to develop a Bibliographic Portfolio on the contribution of public green spaces to promoting quality of life through a systematic literature analysis applying the Proknow-C method (Knowledge Development Process – Constructivist). Theoretical Framework: One of the main challenges faced by cities is the need to balance urban development with environmental preservation, integrating vehicle flow, pedestrian movement, and efficient waste management. In this context, there is a growing focus on the concepts of "environmental quality" and "quality of life," leading to studies that seek to understand how elements of the urban environment can contribute to people's well-being and the improvement of their quality of life. Public green areas are characterized by the presence of tree vegetation, offering various benefits that ensure environmental quality in urban spaces, such as thermal comfort, soil stabilization through plant root systems, reduction of air, noise, and visual pollution, as well as shelter for wildlife. Method: The study's method comprises Proknow-C, which involves selecting and analyzing relevant articles on the subject to create a bibliographic portfolio that enables literature analysis. The most significant research in the scientific literature at both national and global levels was presented. Results and Discussion: During the process, 95 articles were identified as relevant to the topic, forming the Bibliographic Portfolio (BP) of this research. Brazil is noteworthy as one of the countries that contributed the most publications, accounting for 57% of the articles in the BP. Regarding the growth of studies related to green spaces, the years 2022 and 2023 stand out, corresponding to 31% of the total publications in the BP analysis. Research Implications: It is important for future research to investigate innovative strategies for integrating green infrastructures in urban areas. Investing in expanding and improving these spaces can contribute to healthier, more sustainable, and resilient cities.

Objective: This study aims to quantify areas with vegetation cover in the Tambaú neighborhood of João Pessoa, Brazil, using NDVI and NDBI analyses, and to assess the influence and benefits of these green spaces on urban quality of life. Methodology: To achieve this objective, remote sensing techniques were employed to better understand vegetation phenology at varying spatial resolutions, supporting local urban planning efforts. Quantitative analyses were conducted using cartographic data and Google Earth imagery, complemented by qualitative assessments through site visits and photographic documentation. Results: Although the Tambaú neighborhood contains some public green spaces, they are limited and poorly distributed, restricting leisure opportunities for residents. These areas are mostly concentrated in the tourist zone along the coastline. NDVI and NDBI analyses highlight ongoing urban expansion processes, which have led to reduced vegetation coverage and diminished thermal comfort. Additionally, the lack of adequate urban planning negatively impacts quality of life, underscoring the urgent need for more integrated green infrastructure. The revitalization of the Environmental Preservation Area along the Jaguaribe River is a positive initiative, but remains insufficient. Social and Environmental Contributions: This study provides valuable data to inform urban planning and promotes an integrated perspective that incorporates both social and environmental dimensions, contributing to more equitable and sustainable urban development
