Article
Most conventional models in maritime logistics focus uniquely on cost-minimization, whereas the supply chain management literature and practice emphasize customer time-performance and delivery reliability. In addition, the environmental perspective, in particular carbon dioxide (CO2) reductions, is highly relevant. This paper addresses this issue b...
Article
This article analyzes water governance models in the context of sustainable development. Specifically, it aims to understand which dimensions of these models need to be rethought to meet the sustainable development goals (SDGs) of the UN 2030 Agenda, especially SDG#6, considering the uncertainty caused by the COVID-19 pandemic. We present a broad r...
Chapter
Port management is the way in which public and private incumbent actors define, combine, and intertwine their spheres of influence in order to organize and foster port activities. It represents a variety of models built on the base of different institutional, social, historical, and economic frameworks. Core differences among the three major port m...
Chapter
Short sea shipping (SSS) is a concept that refers to short-range maritime transport. SSS has been the subject of detailed analysis and debate in international Transport Policy due to its capacity to articulate intermodal chains for domestic traffic in place of trucking. Due to the fact that SSS was widely assumed as the most sustainable transport o...
Article
This paper aims to analyse cruise tourists' sustainable behaviour and their level of satisfaction at destinations. A semi-structured questionnaire was administered to a sample of 1180 cruise tourists at one major port of call in the Mediterranean region. This allowed us to group cruise tourists into clusters, according to their characteristics, and...
Article
While port efficiency has been broadly researched in recent years, studies analyzing effectiveness are more recent. Both efficiency and effectiveness play an important role in assessing port performance. As some authors state, we can relate efficiency to “doing things right,” whereas effectiveness refers to “doing the right things.” In this chapter...

The Spanish port system represents approximately 20% of the transport sector’s GDP. We analyse the impact of ownership structure, in particular the family characteristics of Spanish port services companies, on profitability. Our study reveals that the ownership of these companies is highly concentrated, with more than 80% having a dominant sharehol...
Article
Specialisation is a common strategy followed by ports to face the challenges of globalisation, changes in the naval industry and maritime operations. The main objective of this research is to determine if specialisation and size of ports have an impact on port efficiency. We estimate the efficiency of 27 Spanish ports during the 2001–2011 period us...
Chapter
Ports are a key part in the development of international trade and, therefore, in the economic growth of countries. Despite the fact that one-third of African countries are landlocked, shipping remains the main gateway to the world market. In this chapter, we present different indicators of the performance of ports in Eastern Africa that could be p...
Article
We use a stochastic frontier approach to estimate the technology and the technical efficiency of a sample of small-scale fishing boats in the Spanish island of Gran Canaria. Using a model that allows for the determinants of inefficiency, we find that boat efficiency increases with boat size while it is inversely related to the age of the vessel. We...
Chapter
With the opening of the Panama Canal, Chile is adapting its transport logistics to the expected arrival of larger container vessels by assuming the establishment of a hub port in its central region. This paper tackles the feasibility of the intermodal chains through MoS to feed the North and the South regions from this central hub port. Due to the...
Article
This study investigates Management Control Systems (MCS) in supporting Port Authority (PA) decision-making processes to prevent and reduce negative environmental effects from seaports. We focus on information management (data collecting, processing and reporting) in the inter-organisational relationships system established among the stakeholders in...
Article
The unbalanced evolution of the environmental normative in the European Union for the different transport modes has led to a broader debate about whether Short Sea Shipping is still a green transport mode. This discussion is especially pertinent because there is no technological alternative indisputably identified as the most adequate one to meet t...
Article
Since the mid-twentieth century, economic growth has yielded a major transformation in the maritime transport industry and, subsequently, in the way ports are organized and managed. The generalization of containerised cargo, accompanied by the increasing size of container ships, have not only changed port infrastructure and operations, but also aff...
Article
The recent European regulations on emissions from heavy duty vehicles (Euro VI) along with the enforcement of ECA regulations have represented an additional challenge for the sustainability of the motorways of the sea. The main aim of this paper is to identify the optimal sizing and the most adequate propulsion plant for a fleet of feeder vessels t...
Article
Full-text available
There are a multitude of factors, both internal and external, that may affect the development and success of any transport project. ‘Success’ is both context-dependent and quite difficult to measure. This paper distinguishes between four types of ‘success’ variables: (lack of) cost overruns; (lack of) time delays; (ex-post) level of traffic; and (g...

Article
Extensive use of containerized cargo has caused technological changes in the maritime industry and consequently port transformations. To face these new challenges, port reform processes were designed, coming to Latin America in the 90s. The main objectives were the modernization of ports and the promotion of competition and efficiency. However, the...
Chapter
Le succès de la participation du secteur privé à un projet d’infrastructure est étroitement lié à la capacité des pouvoirs publics à concevoir et à contrôler judicieusement la relation contractuelle liant les secteurs public et privé. Aussi importe-t-il de bien définir le mécanisme destiné à encadrer la participation du privé, tant en amont (contra...
Chapter
The success of private sector participation in infrastructure is highly conditioned by the ability of governments to properly shape and control the public-private contractual relationship. Therefore, determining the accurate mechanism to control private participation becomes imperative, both ex-ante (by designing correct contracts, properly assigni...
Article
Public-Private Partnerships (PPPs) have proved to be more than adequate as a means to develop transport infrastructure, especially in the case of large-scale infrastructure such as ports. However, under certain specific circumstances they can lead to certain failures, and so huge public losses. Both the country's hard-hit economy and its vast exper...
Article
Chile has a successful track record of introducing private finance in infrastructure investments (including ports) through concession contracts. However, under the current concession scheme, there is a high degree of risk associated with very large civil engineering works involved, such as building breakwaters for mega-port initiatives. In this pap...

Article
From the perspective of Short Sea Shipping (SSS), as an intermodal competitor in the freight market, the time spent within the whole transport corridor is a major issue, in contrast to deep sea shipping where differences in time may not be as relevant as, for example, the contract of carriage or a ship’s position, among other aspects. Although ther...
Article
Despite the European Union (EU) efforts promoting policies that encourage short sea shipping (SSS) based on its advantages in terms of intermodality and environment, this mode has not yet reached a significant market share compared to land transport. In this paper, we establish a thesis that suggests that funding programs (such as Marco Polo I and...
