Plastic Discharge in Bali’s Rivers
No full textIndonesia is one of the largest ocean pollutants in the world in terms of plastic emissions. The country has many tourist areas, including the island of Bali, which is the main tourist hub. The plastic problem is large around and on Bali, which has negative consequences for both the environment and the tourism sector. NGOs and the government are trying to tackle the plastic problem, with an increasing effort in the last few years. This research project has been set up to determine which regions and rivers in Bali discharge the most plastic and therefore pollute the ocean the most, and to design a river structure to mitigate plastic emissions to the ocean.For this study, 31 rivers in eight different regions were measured and analysed. All rivers were measured by visual observation, a trawl or a combination of the two. The flow velocity and the width were measured for each river. By means of the average weight of one piece of plastic, the plastic flux could be obtained. The river embankments were systematically assessed for each river. In addition, the wind speed was also measured for each river.The three most polluting rivers of the island are all in different regions. These three rivers will be the most effective to tackle in order to reduce the plastic discharge to the ocean. The study shows that when a river flows through a densely populated area, the river is more polluted, as is the case with the three most polluted rivers.Through a MCA, two effective waste catchment structures were eventually found for the two types of rivers on the island, which are rivers with and without navigation. The structures will remove the plastic from the rivers. The structure for the river that can be closed is the Trash Trap, and for the river that cannot be closed is the Sea Defence Structure.Master project reportCivil Engineering Consultancy Project | CIE4061-09 | MP287Civil Engineering | Hydraulic Engineerin
Financing of Litigation by Third-Party Investors: A Share of Justice?
No full textThis article addresses the issue of the funding of civil litigation within the framework of access to justice and the normative goal of increasing access to the civil justice system. The author critically analyzes and cautiously advances the case for the recent development of the financing of litigation by third-party investors. The argument is that investor financing has the potential to increase access to the civil justice system by ameliorating the economic barriers to litigation. The author evaluates investor financing against existing public and private models of financing litigation such as legal aid plans, litigation subsidy funds, and contingent fee arrangements. The doctrines against maintenance and champerty, which prohibit third parties from providing financial assistance to litigants, are reviewed and analyzed in order to assess the enforceability of financing agreements between plaintiffs and investors. The author then examines the market that is likely to develop for the financing of litigation and analyzes regulation that may be required to protect investors and plaintiffs. The author evaluates policy concerns in relation to the wide-spread availability of investor financing and concludes that such concerns are either misguided or can be addressed by implementing appropriate regulatory safeguards
Ports in Transition
No full textPorts worldwide are confronted with a changing environment in terms of global economy and a rising awareness of the necessity of balancing economic, social and environmental interests. Therefore, in recent years, a lot of research has been directed towards studying sustainable port development. However, the focus has been on greenfield ports, while little has been said about ports in transition. This paper presents a framework for sustainable development of ports in transition and applies it to the re-development of bay of Havana in Cuba
The critical areas of information sharing for the improvement of efficiency in the nautical chain: A Port of Rotterdam case study
No full textRecently, pressure on port authorities to improve port efficiency is increasing due to port competitiveness. Multiple activities within a port influence the efficiency of a port. In this research, the processes of the 'nautical chain' are considered. The nautical chain consists of piloting by a pilot, positioning by tugboats and (un)mooring by boatmen. The provided services are dependent on each other, which makes information sharing between the actors of the nautical chain essential. Enhancing information sharing in the nautical chain could provide opportunities for efficiency improvements. However, current literature does not provide any details on information sharing in the nautical chain. Consequently, it is unknown what parts of the information sharing might be crucial to focus on for improving its efficiency. This research aims to fill this gap, by researching the information that is shared in the nautical chain of the Port of Rotterdam in the delays that frequently occur through expert interviews and observations. The information that is shared in the frequent delay situations is considered critical for efficiency improvements, because the shared information contributes to decisions that reduce the cascade effect of a delay trigger. Following from the identified information sharing in the frequent delays, the areas of critical information sharing are distinguished.Transport, Infrastructure and Logistic

No full textIn spite of the major and broad consequences of adverse climate change impacts on ports in general, relatively little and relevant detailed research is made available within public domain. Several studies have addressed climate impacts on transportation infrastructure however very few focus on ports and supply chain. Ports are considered critical infrastructure that serve as a catalyst for economic growth and development of a country. Their importance is not only on a national (or regional) level, but they act as gateways to trade and constitute essential nodes in the global supply chain. The topic of this thesis on \textit{Climate Change Impact Assessment on Ports} is very broad to tackle within only 9 weeks (the length of this research). Therefore, the focus has been set on seaports within the Netherlands and more specifically, the Port of Rotterdam as main example. This thesis aims to advance research on climate change impact assessment on ports and supply chains. To achieve the aforementioned, a few research questions have been defined to help steer the research into the right direction: (1) What is known about the main impacts of climate change on ports and supply chains? (2) Which assets are vulnerable to the main impacts determined in sub-research question 1? (3) What are the state of the art strategies to perform a climate change impact assessment? And what are the available resources (frameworks, methods, software)? (4) Which knowledge gaps have been identified while answering sub-research questions 1,2 and 3? (5) How can one address the gaps identified in sub-research question 4? The methodology of this thesis has two main parts: The literature study and the expert interviews. The interviews were a very important part of this research. That is because this thesis aims to present the needs from the users perspective, to motivate researchers to continue with the exploration of this topic. Formulating the right questions to ask the experts and identifying which of the 12 experts could provide the best answer to understand the needs from different port users perspective, was the most challenging part of this thesis. The results of this thesis are research topics on the broad subject of climate change impact assessment on ports an supply chains. Due to time constrains, only 3 research topics are presented in more detail with the corresponding suggested approach. These three topics have been prioritized among the rest based on expert's opinions on what climate change issues are the most urgent (for further details see 2.4.2 \& 4.1-4.3). These topics are: (1) Developing an Integrated Stochastic Model to Test Climate Change Resilience on Ports, (2) Investigating Methods to Identify \& Quantify Supply Chain Disruptions due to Climate Change Cascade effects and (3) Developing a Method to Promote Awareness for Climate Change Resilient Ports. Nevertheless, chapter 6 presents a list of other potential research topics that can also be of interest to researchers. The recommendations for further research on the topic of climate change impact assessment on ports and supply chains are to follow the suggested research topics descriptions in chapter 6. Furthermore, to explore probabilistic models to tackle uncertainty issues and to understand the multivariate dependencies within ports and supply chains. Finally but most importantly, this research should be extended internationally, not only focusing on Dutch experts, to have a global perspective on the problems and the identified knowledge gaps posed on this thesis. Other recommendations can be found in chapter 7.Additional thesi
