Sustainability at Spanish ports specialized in liquid bulk: evolution in times of crisis (2010–2015)

In Spain, 28 Port Authorities of general interest moved more than 168 thousand tonnes of liquid bulk (34% of overall traffic) in 2015. Almost 82% of this amount corresponded to eight ports (G-8) that have a refinery within their facilities. This unique degree of specialization and concentration makes this set of ports an ideal sample to analyse the evolution of their sustainability levels, particularly during the crisis started in 2008 and onwards. A proprietary methodology based on Multidimensional Synthetic Indices has been used. The comparison of the findings obtained for 2010 and 2015 allows a diagnosis of the evolution of port sustainability measured through the economic, institutional, environmental and social dimensions to be established, as well as a study of the patterns of behaviour that each port has followed in this issue.     

传播动力学视角下集装箱海运网络关键港口节点识别

将船期延误与重要港口节点的识别问题相结合，通过传播动力学模型，对世界集装箱海运 网络的传播特性进行分析，发现港口节点传播能力与度值满足幂为16.84的幂律分布，具有无标 度特征，且度值与传播影响力的相关性较强。以 SIS(Susceptible-Infected-Susceptible)模型为基 础，结合网络结构特性，比较不同节点传播影响力评估方法发现，节点间最短路径长度是衡量节 点传播能力的一个重要因素。基于引力模型，提出考虑度值、节点核心位置及节点间最短路径长 度的综合取值法，验证了改进引力模型在世界集装箱海运网络节点传播能力评估中的适用性，发 现综合取值法对模型精确度提高有促进作用。研究得到：世界各港口传播影响力排序，为关键港 口的识别提供了不同视角；高传播影响力港口普遍集中在亚洲区域，其次为欧洲地区；高连通性 与高传播影响力无正相关性。

Evaluating the social cost of cruise ships air emissions in major ports of Greece

Detailed NO_x, SO₂ and PM_2.5 emissions have been estimated for cruise ships in the five busiest Greek ports (i.e. Piraeus, Santorini, Mykonos, Corfu and Katakolo) for year 2013. The emissions were analyzed in terms of gas species, seasonality and activity. The total in-port inventory of cruise shipping accounted to 2742.7 tons: with NO_x being dominant (1887.5 tons), followed by SO₂ and PM_2.5 (760.9 and 94.3 tons respectively). Emissions during hotelling corresponded to 88.5% of total and have significantly outweighed those produced during ships’ maneuvering activities (11.5% of total). Seasonality was found to play a major role, as summer emissions and associated impacts were significantly augmented. The anticipated health impacts of ship emissions can reach to €24.3 million or to €5.3 per passenger proving the necessity of control of the emissions produced by cruise ships in port cities or policy and measures towards a more efficient cruise industry.     

The strategic role of ports in regional development: conceptualising the experience from Australia

Regional ports, as infrastructure in regions, influence transport and regional development policies and planning. The interaction and involvement of regional ports with their stakeholders in the region are pivotal. The conundrum on what constitutes a regional port and thus its region has further complicated this limited researched area. In the extant literature, port and region relationship mainly centres on major metropolitan ports, and pays little heed to regional ports. In this context, this study investigates on how the Australian regional ports can be better involved in regional development. The study adopts a qualitative methodology to explore the Australian regional port stakeholders’ perceptions on port’s role in regional development through 38 semi-structured telephone interviews. Thematic analysis of data assisted by a mixture of NVivo software and manual techniques proposes a conceptual model that may assist policy-making. The key findings suggest that symbiotic growths of ports and concerned regions accelerate regional development. To contribute to regional development, the Australian regional ports can be proactive in building collaboration with regional organisations. The findings have major implications for port managers and port policy-makers for developing a region-oriented long-term port planning and for creating environment for Australian regional ports for regional resource configuration.     

Ship emissions and their externalities in cruise ports

This paper presents an estimation and analysis of ship exhaust emissions and their externalities in the popular cruise destinations of Dubrovnik (Croatia) and Kotor (Montenegro) along the eastern coast of the Adriatic Sea. To this extent, the recent record (2012–2014) of cruise ships calling at these ports is used to model and estimate the ship exhaust emission inventories and externalities within the associated bays and ports.The results indicate that cruise ship traffic produces continuously increasing air pollution in both ports over recent years. More importantly, however, the analysis of the ship operating characteristics reveals that for any given ship traffic involving specific vessels using marine fuel of a given quality, the presence of other factors (e.g. berth availability, berth accessibility etc) can also influence the ship emission levels. This is particularly evident in the case of the port of Kotor where berth space insufficiency dictates the need for ship anchorage thus leading to increased air pollution and costs of associated damage.The application and results of the aforementioned ship activity-based methodology to the ports of Dubrovnik and Kotor improves our understanding of ship emissions in cruise bays and ports, and contributes toward the implementation of port policies for the effective control of air quality in such environmentally sensitive locations.
