Noise has long been neglected as an environmental pollutant and impairment health factor in maritime transport. Recently, acoustic pollution indicates the highest growth in transport external cost unit values. In 2020, questionnaires were submitted to seafarers to examine their noise exposure and perception on board and attitudes towards noise abatement measures. Responses of 189 participants were processed using descriptive statistics and Likert scale valuation, while their consistency was tested with indirect indicators using linear regression and correlation test. Results show that more than 40% of respondents do not consider noise as a significant environmental problem. The negative perception among respondents with ≥10 years of work experience was much lower (23.53%). Most are aware of the onboard noise harmful effects that can influence their health. Despite that, they use personal protection equipment only sometimes. A higher positive perception was recorded in groups of respondents with a university degree (90%), work experience longer than ten years (82.35%), and monthly income higher than 4000 € (70%). Respondents are not strongly motivated to participate in funding noise mitigation measures, and such a viewpoint is not related to their monthly incomes. The low awareness and motivation regarding acoustic pollution generally shown by the surveyed seafarers should be watched as a threat by the company managers. Better education and awareness are likely to be crucial to change the current state of affairs.

The impact of cruise tourism on key stakeholders determines further development of the cruise industry on a destination, imposing an obligation to systematically and continuously monitor stakeholders’ perceptions and attitudes. During 2019, primary research was conducted to examine two keys components of the cruise activity at the destination: the impact of cruise tourism on the local population and stakeholders performing business activities in the port of Split. Two individual groups of survey questionnaires were created. Special attention was given to the social, economic, and environmental impacts of cruise tourism, respecting the principles of sustainable development. These values were estimated based on the Likert scale. The local population considers the economic and social effects of cruise tourism as exceedingly positive and is more prepared for tolerance and resilience to achieve the expected well-being. Local business stakeholders are more restrained and record a minimal increase in income and employment related to the cruise activity. Limited perception and knowledge on sustainable development in the port of Split are characteristic of both groups of respondents.

Measures needed to be implemented by the Port Authority at the maritime domain of the Port of Split in order to strengthen maritime traffic and stimulate economic development of the city were examined by conducting the structured questionnaire among concessionaires in the port area. The collected data were processed using the Friedman test and Sign test. Among six options, the concessionaires mostly indicated variable of building an infrastructure that will promote and attract the presence of different forms of maritime traffic in the port as the best choice for the initial purpose. Different forms of maritime traffic enable more business opportunities to compensate for the potential operating loss in case of declining maritime traffic. The Port Authority should consider the concessionaires' attitude, despite the possibility to express their own business interests within, as their business results are closely related to the size of maritime traffic in the port.
