Abstract: The primary objective of this research endeavor is to conduct an in-depth literature review on the paramount significance of Nature-Based Solutions (NbSs) in mitigating carbon footprint and enhancing the resilience of critical infrastructures, with a specific emphasis on road transportation infrastructure. Additionally, the aim is to map available NbS to enhance road infrastructure resilience in the face of climate change impacts and identify key challenges and potential solutions. The findings indicate that, despite limited research dedicated to the transportation sector, NbS exhibits significant promise in advancing environmental sustainability and fostering climate change adaptation. These solutions encompass a spectrum of approaches, such as integrating natural elements into road infrastructure and restoring adjacent ecosystems. Furthermore, knowledge gaps and challenges related to the implementation of NbS in the transportation sector are identified. These findings guide future research and encourage the adoption of policies and strategies that promote the effective integration of NbS into transportation policies and existing/future infrastructure projects.

Abstract: The chapter explores the opportunities arising from the Belt and Road Initiative (BRI) and its current expansion into Latin American territory, analyzing dilemmas that emerge within the context of shifts in global geopolitics. The BRI, initially launched in 2013 to connect Asia, Eastern Europe, and Africa, aims to stimulate international trade by fostering collaboration with Chinese enterprises on a global scale. The initiative has incorporated Nature-Based Solutions (NbS) into its environmental cooperation program after a recommendation from the Chinese Council for International Cooperation on Environment and Development (CCICED), a government-affiliated think tank, to achieve domestic climate and biodiversity goals. The expansion of the BRI into Latin America brings significant implications, especially in the context of Sino-American rivalry and US influence in the region. This dynamic, constantly evolving, raises complex challenges, particularly regarding the Sustainable Development Goals (SDGs) and the 2030 Agenda. Within the scope of climate change, SDG 13—Climate Action—stands out due to its global relevance. Climate change directly affects ecosystems and communities worldwide, making it crucial to consider mitigation and adaptation strategies in development initiatives like the BRI. Furthermore, SDG 11—Sustainable Cities and Communities—is essential to consider as the infrastructure developed under the BRI can have significant impacts on urban and rural areas, influencing the quality of life and sustainable development of these communities. Therefore, while the BRI offers opportunities for economic development and regional connectivity, addressing environmental and social issues, adhering to sustainability principles, and seeking synergies with the SDGs, especially those related to climate action and sustainable community development, are crucial.

Abstract: Monitoring highways and obtaining traffic data are relevant for planning and programming new investments. This data often comes from automatic counting stations or roadside traffic surveys that can also obtain socioeconomic and trip origin and destination information. This paper presents novel contributions to address the Bi-objective Support Unit Location Problem to Assist Roadside Traffic Survey with Multi-Stages (BSULP). The objective of this research is to propose an approach to optimize two conflicting objectives simultaneously: minimizing travel costs from support units to survey stations and minimizing the number of selected support units. To achieve this, we propose three modified versions of the NSGA-II algorithm, with tailored strategies for constraints handling of the BSULP. These strategies involve a significantly reduced structure for the chromosomes, and initial population, crossover and mutation algorithms that maintain the feasibility of the solutions. For a benchmark of instances, we implemented an exact -Constraint method, and the results were compared with different versions of modified NSGA-II using Hypervolume (HV) and Generational Distance (GD) metrics. The best results were obtained with the M3NSGA-II version, which on average represented more than 94% (HV) and less than 17% (runtime) of the exact method. In addition, it was possible to obtain solutions for large instances which was not possible with the exact method.

Abstract: Climate change poses several challenges for the transportation sector due to its high vulnerability to climate and weather conditions, as well as the impacts of extreme weather events. These events have a direct influence on the useful life of infrastructure and transportation safety. This underscores the need to incorporate climate change considerations into regular transportation infrastructure projects, highlighting the importance of conducting a comprehensive Climate Risk Analysis (CRA). This study aims to examine several key CRA methodologies in the transport sector, emphasizing their prominent advantages and identifying significant challenges. In addition, it highlights the importance of an integrated approach, highlighting the convergence of these methodologies. This provides a comprehensive overview of the essential elements to be considered in a CRA, highlighting the need for a holistic approach to dealing with the impacts of climate change in the transport sector

Abstract: A crescente demanda global por uma economia mais sustentável está impulsionando a exploração de alternativas às práticas convencionais. A adoção de um sistema de produção e distribuição de hidrogênio está ganhando consenso global, impulsionada por seu menor impacto ambiental em comparação com os combustíveis fósseis. Este estudo investiga a viabilidade do hidrogênio renovável, proveniente de vias como a energia solar e eólica, especialmente no âmbito do transporte urbano sustentável. A urgência de tecnologias inovadoras, ressaltada por metas de emissões e objetivos de desenvolvimento sustentável, posiciona o hidrogênio como uma solução promissora com valor calorífico superior e emissões reduzidas. No entanto, desafios formidáveis, incluindo infraestrutura limitada e a necessidade de investimentos substanciais, representam obstáculos significativos para sua adoção generalizada. A pertinência deste estudo é ainda mais enfatizada pela necessidade de atualizar continuamente a literatura, garantindo o alinhamento com os desenvolvimentos dinâmicos nesse campo.
