Delivering tourism sustainability and competitiveness in seaside and marine resorts with GIS /
No full textIn 2015, the United Nations General Assembly identified 17 Sustainable Development Goals (SDGs) to be achieved by the year 2030. The study’s main objective is to identify the necessary conditions and potential for ensuring both the sustainability and competitiveness of tourism in seaside and marine resorts located in or at coastal and marine protected areas on the example of Karklė (Lithuania). Based on the results of a benchmarking study of five South Baltic resorts using the Delphi technique, the survey team identified the main deficiencies of Karklė as a seaside and marine resort of an international scale. We address the deficiencies by applying a geographical information system as a decision-support tool for the Littoral Regional Park where Karklė is located. We conclude that for ensuring both the sustainability and competitiveness of tourism in seaside and marine resorts, it is expedient to combine the Delphi-based tourism benchmarking with integrated coastal management and maritime spatial planning, for which GIS is an indispensable tool
Innovation project risk management: the case of telecommunications companies.
No full textThe topic, examined in this Master's thesis is innovation project risk management at Lithuanian telecommunications companies. The purpose of the research is to establish the methods of innovation project risk management at Lithuanian telecommunications companies and create the most efficient model for innovation project risk management. The study uses a qualitative research method – a semi-structured interview. The data is analysed by conducting a qualitative content analysis. Research results have shown that Lithuanian telecommunications companies use traditional risk management methods for their projects. It became evident that companies do not use quantitative risk analysis methods. The analysis of the research results was followed by constructing an innovation project risk management model and offering recommendations

No full textUrban sewage water pathways seem most important for microplastics emissions to the Baltic Sea. We use microplastics emission data for the entire Baltic Sea region, calculate emissions for three sewage water related urban pathways and develop emission scenarios for the majority of microplastics particles. All plastics are divided into potentially floating (density 0.8–1.0 g/cmł) and sinking (1.1–1.5 g/cmł) polymers and we address the size class of 20–500 μm. 6.7 × 1013 microplastics particles enter the Baltic Sea annually from urban pathways. 62% result from stormwater runoff including sewer overflow, 25% from wastewater treatment plants (WWTPs) and 13% from untreated wastewater. The emission scenarios serve as input for 3D-model simulations, which allow estimating transport, behaviour and deposition in the Baltic Sea environment. Our model approach suggests average annual microplastics concentrations in the water body of the central Baltic Sea of 1–4 particles/m2 sea surface and 1 particle/m3 in the upper 2 m sea surface layer. The majority of the particles is accumulated in upper sea surface layers. The model suggests that only between 6% (Arcona Basin) and 21% (Gotland Basin) of the particles are below a depth of 25 m. In coastal waters, the concentrations can exceed 10 particles/m3 in the upper 2 m surface water layer (e.g., Gulf of Riga, Gulf of Gdańsk) and 1 particle/m2 on the sediment surface. Usually within weeks, emitted microplastics are washed ashore causing annual coastal accumulations of up to 109 particles/m coastline within a few kilometres distance to emission sources. On average, above 106 particles/m are annually accumulated and trapped at coasts around the Baltic Sea. The reduction of the annual sewer overflow from presently 1.5% of the annual wastewater loads to 0.3% would reduce the total emissions to the Baltic Sea by 50%. If all sewage water would be connected to WWTPs and undergo a tertiary treatment, a reduction of 14.5% of the total emissions could be achieved. The effect of retention in rivers seems limited in the Baltic Sea region, because near coast emissions contribute around 50% of the total microplastics emissions
