Logistica Portuale e ambiente
No full textDiversi incidenti marittimi, categorizzati come disastri ambientali che hanno avuto luogo nelle ultime decadi (sversamenti di sostanze tossiche, naufragi, ecc.) hanno messo il settore sotto i riflettori. Anche se il trasporto marittimo è considerato quello meno dannoso per l’ambiente, la continua crescita ed espansione della sua attività richiede lo sviluppo di azioni precauzionali volte ad assicurare la sostenibilità. Dopo una breve introduzione sull’attualità del tema in questione, l’articolo analizza la difficoltà nel trovare una definizione universalmente accettata di cosa sono le Green Port policy e tenta di fornire una definizione di massima il più ampia possibile (paragrafo 2). Il paragrafo 3 si concentra sulla principale sfida ambientale in ambito portuale descrivendo una delle strategie più utilizzate. Lo scopo finale è quello di fornire alcuni spunti di riflessione sul futuro della sostenibilità portuale (paragrafo 4)
Consequences of demographic changes on urban mobility: an overview of ageing in modern societies
No full textThe italian roll-on roll-off sector: from the puzzle of statistics to a realistic scenario
No full textThe purpose of the paper is that of analysing the available sources of information for the Italian roll‐on
roll‐off and underlining the strengths and weaknesses of this data.
As a matter of fact in the Short Sea Shipping the roll‐on roll‐off transport represents an important leg of
the intermodal maritime combined transport. For this reason and considering the accessibility to the data
made possible by the Information Communication Technologies, the analysis of this mode of transport
should be simple, yet in reality it is not so.
Actually the chosen sector does not always register the availability and quality of information that is
present for other types of transport (such as container lift‐on lift‐off or cruises). Even though the roll‐on
roll‐off transport is the core of the Motorways of the Sea, the historical series for the Italian market that
can be consulted often present a certain amount of gaps. In fact, if on the one hand the official statistics
published periodically by the Port Authorities contain information on the volume of annually handled
goods, on the other, this same elaborations are not always comprehensive (especially in less structured
ports) on the most significant features of the traffic flows, such as the origin and destination of the
maritime relations.
To solve this problem, it is possible to use some analysis carried out at central level (by the Italian
Institute of Statistics and Eurostat) that could be useful to overcome the existing gaps, yet the chosen
measure units differ from that of the Port Authorities. Here lies the main difficulty of reaching a sufficiently
detailed description of the market that should support the choices of the operators but in particular the
formulation of actions aimed at fostering modal shift from road to sea.
The paper is structured as follows: Section 1 concerns the introduction and methodological aspects;
Section 2 addresses the Italian scenario and defines the sample (most important ports regarding Italian roll-on roll‐off market); Section 3 Takes into account the main relations of Short Sea Shipping and it focuses the
analysis on some features of the traffic flows in the chosen ports. Section 4 contains some final
considerations regarding the exploitation of the sources of information and the improvement of the roadsea combined transport's appeal
Port hierarchy and concentration: Insights from the Mediterranean cruise market
No full textThe cruise industry provides a tourism service that is performed entirely by means of transportation: the vessel. Although different characteristics of the cruise industry are well documented in the related academic literature, the role and influence of ports (and port cities) in defining cruise organisation is relatively understudied. Using public official data collected from all the major cruise groups operating in the Mediterranean Sea, we investigate the role of the different ports (and cities) within different itineraries. The analysis highlights that although there is some sort of hierarchical structure among some main ports included in the Mediterranean cruise routes, the majority of the ports of call are in a somewhat vulnerable position within the cruise transport network. Moreover, the study discusses how ports’ characterising elements, such as excursion packages, have a strategic role in ensuring the inclusion of peripheral ports within the cruise network
Energy management in seaports: A new role for port authorities
No full textPorts are characterised by the geographical concentration of high–energy demand and supply activities,
because of their proximity to power generation facilities and metropolitan regions, and their functions as
central hubs in the transport of raw materials. In the last decades the need to better understand and monitor
energy-related activities taking place near or within the port has become more apparent as a consequence of
the growing relevance of energy trades, public environmental awareness and a bigger industry focus on
energy efficiency. The uptake in the port sector of innovative technologies, such as onshore power supply, or
alternative fuels, such as LNG, and the increasing development of renewable energy installations in port
areas, also calls for more attention to energy matters within port management.
So far, however, few port authorities have actively pursued energy management strategies. The necessity
for port authorities to actively manage their energy flows stems from their efforts to plan, coordinate and
facilitate the development of economic activities within the port, and as a consequence of the heavier weight
that sustainability is given within the port management strategies.
Through the analysis of the experiences of two European ports, Hamburg and Genoa, that have
already attempted to coordinate and rationalise their energy needs, this paper will argue that for the ports of
the future active energy management can offer substantial efficiency gains, can contribute to the
development of new alternative revenue sources and in the end, improve the competitive position of
the port
Event-oriented traffic management: policies from Stuttgart and Genoa experiences
No full textMore and more frequently, special events generate spatial and time convergence traffic flows that result in transportation problems.
Mega events generate unusual problems regarding forecasts of attended traffic flows that have to be added to transport demand present in normal circumstances. Often city authorities deal with these situations by means of new infrastructures (if possible) and specific transport measures for the event to ensure efficient management of traffic flows.
The goal of this paper is to outline the network design philosofy and offer some intuitions that have been gained from transport authoritie3s of two cities during big events: Stuttgart and Genoa. Moreover, the paper has the purpose of offering transport strategies transferable to other cities involved in planning mega events
Coastal city and ocean renewable energy: Pathway to an Eco San Andres
No full textProactively planning for sustainable coastal cities is increasingly important as climate change increases the frequency and intensity of extreme weather events. Scientific research indicates that greenhouse gas emissions, mainly induced by using non-renewable energy, are elevating temperatures and sea levels for coastal cities all around the world. Other issues that aggravate the challenge for coastal cities include: the continued growth of population on and around coastlines; the acute conflict between increasing energy demand and decreasing amount of natural energy resource. All evidences lead to one fundamental element for coastal eco cities: utilizing renewable energy from the ocean to make coastal cities more ecologically and economically sustainable.
The subject of this study is San Andres, a Colombian island in the Caribbean Sea that was declared as UNESCO Biosphere Reserve in 2000 for its well-preserved ecosystem and biodiversity. Regrettably, it is currently 100% dependent on imported fossil fuels and has a high level of greenhouse gas emission. The mono economy relying on tourism implicates financial incentives of various stakeholders to seek an eco solution. The system boundary of this study is drawn to transform San Andres into an oasis of sustainability for both inhabitants and tourists by using ocean renewable energy.
The pathway for such transformation starts with an intuitive thinking about the essences of coastal eco cities by conducting a SWOT analysis. A promising selection of ocean renewable energy has been investigated in-depth: solar, wave, wind and Ocean Thermal Energy Conversion (OTEC). After identifying the legal constraints, this study proposes an ocean renewable energy portfolio based on two scenarios comprehensively considering various investment scales and energy consumption: government-centred scenario and community-oriented scenario. It is shown that the production of clean energy under both scenarios has lower cost than the current generation cost based on fossil fuels. The implementation of the scenarios might positively affect other aspects of the city such as improving water supply, lowering the demand of electricity, increasing community involvement. Marketing scheme and transferability to other tropical island cities have been developed in the later parts
