The new business environment, and the new era of digital transformation put pressure on the global supply chain and accordingly on ports to cope with such changes; these require ports to be smarter and adapt to the new technological approaches. Smart ports SP express the prevailing trend for the transformation strategies. Although many previous studies discuss smart ports requirements there is no integrated vision provided before to capture different comprehensive elements of smart port and show its impact on sustainably. Therefore, this research aims at developing an integrated smart port index SPI, capturing different elements of SP and linking them to port sustainability performance. The research conducted a systematic literature review to identify all pillars that are required for the smart port adaptation and showed its impact on sustainability with a full-text reading stage that resulted in 48 articles. The paper indicated that few studies of the SPI have been proposed before to improve SP activity in different domains: operations, environment, energy, safety, and security; however, there is a need to address the several key issues related to port operations, and to consider human resources factor as part of the smart port requirement, particularly an integrated index that captures different pillars in SP elements and shows its effect on sustainable performance. The study reveals that SP initiatives around the world have different integration levels. According to this, the smart port index can be considered as the first integrated index linked to sustainability and including human resources; however, there are some limitations that could be an open issue to future researchers and practitioners to foster new practical research initiatives that can rely on this index to adapt the smart port practices in different ports, taking into consideration the human resources aspect and testing their impact on port sustainability.

Climate change is a current phenomenon: the temperatures rise, rainfall patterns are changing, glaciers melt and the average global sea level is rising. It is expected that these changes will continue and that the extreme weather events, such as floods and droughts, will become more frequent and intense. The impact and vulnerability factors for nature, for the economy and for our health are different, depending on the territorial, social and economic aspects. The current scientific debate is focused on the need to formulate effective policies for adaptation and mitigation to climate change. The city plays an important role in this issue: it emits the most greenhouse gas emissions (more than 60% of the world population currently lives in urban areas) and the city is more exposed and vulnerable to the impacts of climate change. Urban planning and territorial governance play a crucial role in this context: the international debate on the sustainability of urban areas is increasing. It’s necessary to adapt the tools of building regulations to increase the quality of energy - environment of the cities. Tema.

In Bangladesh, prawn (Macrobrachium rosenbergii) farming remains dependent on the capture of wild postlarvae as hatchery production is still inadequate. However, prawn postlarvae fishing has been accompanied by concerns over recent climate change. Different climatic variables including cyclone, salinity, sea level rise, water temperature, flood, rainfall, and drought have had adverse effects on coastal ecosystem, thus determining a decline in the availability of prawn postlarvae and thereby catch. The households of postlarvae fishers also face a variety of socioeconomic constraints due to climate change. Considering extreme vulnerability to the effects of climate change, an integrated approach needs to be introduced to cope with the challenges.

Several countries have considered banning or even decided to ban or tax super short-haul flights, arguing that the availability of rail alternatives makes them unnecessary. Such policies result from the need for governments to be seen as acting to mitigate climate change and scholars favouring energy (climate) efficiency perspectives over the absolute amount of fuel burnt (greenhouse gas emissions emitted). Yet climate change is due to absolute emissions, and it is a fact that the longer a flight is, the greater the amount of fuel is burnt (emissions). Considering all departing flights from 31 European countries, our study found that flights shorter than 500 km account for 27.9% of departures but 5.9% of fuel burnt. In contrast, flights longer than 4,000 km account for 6.2% of departures but 47.0% of fuel burnt, although with significant variation across countries. We conclude that targeting shorter flights (which often exist to alleviate physical obstacles imposed by physical geography) will contribute little to reducing the impact of aviation on climate, and that policy initiatives that target longer flights are urgently needed. ; info:eu-repo/semantics/published

Estuaries are among the most valuable aquatic systems by their services to human welfare. However, increasing human activities at the watershed along with the pressure of climate change are fostering the co-occurrence of multiple environmental drivers, and warn of potential negative impacts on estuaries resources. At present, no clear understanding of how coastal ecosystems will respond to the non-stationary effect of multiple drivers. Here we analysed the temporal interaction among multiple environmental drivers and their changing priority on shaping phytoplankton response in the Bahía Blanca Estuary, SW Atlantic Ocean. The interaction among environmental drivers and the number of significant direct and indirect effects on chlorophyll concentration increased over time in concurrence with enhanced anthropogenic stress, changing winter climate and wind patterns. Over the period 1978-1993, proximal variables such as nutrients, water temperature and salinity, showed a dominant effect on chlorophyll, whereas in more recent years (1993-2009) climate signals (SAM and ENSO) boosted indirect effects through its influence on precipitation, wind, water temperature and turbidity. Turbidity emerged as the dominant driver of chlorophyll while in recent years acted synergistically with the concentration of dissolved nitrogen. As a result, chlorophyll concentration showed a significant negative trend and a loss of seasonal peaks reflecting a pronounced reorganisation of the phytoplankton community. We stress the need to account for the changing priority of drivers to understand, and eventually forecast, biological responses under projected scenarios of global anthropogenic change.

Inland Waterway Transport (IWT) is recognized as energy efficient, with lower levels of greenhouse gas emissions and large freight capacity when compared to other modes. Therefore, IWT helps to achieve the Sustainable Development Goals in 2030 Agenda (SDGs) that relate to sustainable transport. Still, transport sustainability assessments must include environmental, social and economic issues. This paper reviews recent research aiming to provide a conceptual definition of sustainable inland waterway transport that relates to the SDGs, and to identify gaps in literature for future research. To accomplish this task, a cluster analysis-based taxonomy was built through the intuitive approach, with peer-reviewed papers published between 2015 and 2020. The sample was classified into twelve clusters of IWT sustainability issues, which were related to SDGs and their targets. Results show increased scientific interest in eco-friendly practices. However, social issues remain underappreciated. We present a definition for sustainable IWT and the pathways for future research to achieve higher sustainability levels, as prescribed by the 2030 Agenda.

Marine renewables represent a promising and innovative alternative source for satisfying the energy demands of growing populations while reducing the consumption of fossil fuels. Most technological advancements and energy yield assessments have focused on promoting the use of kinetic energy from tidal streams with flow velocities higher than 2.0 m s−1. However, slower-moving flows from ocean currents are recently explored due to their nearly continuous and unidirectional seasonal flows. In this study, the potential of the Yucatan Current was analysed at nearshore sites over the insular shelf of Cozumel Island in the Mexican Caribbean. Field measurements were undertaken using a vessel-mounted Acoustic Doppler Current Profiler (ADCP) to analyse the spatial distribution of flow velocities, along with Conductivity-temperature-depth (CTD) profiles as well as data gathering of bathymetry and water elevations. Northward directed flow velocities were identified, with increasing velocities just before the end of the strait of the Cozumel Channel, where average velocities in the region of 0.88–1.04 m s−1 were recorded. An estimation of power delivery using horizontal axis turbines was undertaken with Blade Element Momentum theory. It was estimated that nearly 3.2 MW could be supplied to Cozumel Island, amounting to about 10% of its electricity consumption.

The battery pack in electric vehicles is subjected to road-induced vibration and this vibration is one of the potential causes of battery pack failure, especially once the road-induced frequency is close to the natural frequency of the battery when resonance occurs in the cells. If resonance occurs, it may cause notable structural damage and deformation of cells in the battery pack. In this study, the natural frequencies and mode shapes of a commercial pouch lithium-ion battery (LIB) are investigated experimentally using a laser scanning vibrometer, and the effects of the battery supporting methods in the battery pack are presented. For this purpose, a test setup to hold the LIB on the shaker is designed. A numerical analysis using COMSOL Multiphysics software is performed to confirm that the natural frequency of the designed test setup is much higher than that of the battery cell. The experimental results show that the first natural frequency in the two-side supported and three-side supported battery is about 310 Hz and 470 Hz, respectively. Although these frequencies are more than the road-induced vibration frequencies, it is recommended that the pouch LIBs are supported from three sides in battery packs. The voltage of the LIB is also monitored during all experiments. It is observed that the battery voltage is not affected by applying mechanical vibration to the battery.
