The natural tourism potential of Galați town and its sustainable capitalization

Abstract: This study analyzes the natural tourism potential of Galați Town within the context of sustainable development, starting from the quantitative and qualitative assessment of the natural tourist patrimony, with the purpose of highlighting the elements of attractiveness, as well as the local factors that encourage or hinder tourist functionality. The qualitative assessment of the tourist potential, undertaken by quantifying the tourist sights, which were grouped into several types, has allowed the identification of the tourist attractions. A particular attention has been paid to the natural vegetation, which has not been seriously impacted by the human society and which has been protected and preserved within the framework of the Natura 2000 European Programme. The analyses undertaken and the bioclimatic indicators computed based on the existing data prove that in this area the local climate is favorable for the tourist activities. Our interest on this topic stems from the desire to highlight the tourism potential of this geographical space and to promote it at the national level.

Atmospheric Pollution by Iceland Volcano Lava Dispersion – the Brussels Case

Abstract: In April 2010 the Icelandic Eyjafjallajökull stratovolcano emitted large clouds of volcanic ashes that provoked chaotic situations for the air traffic of the Northern hemisphere. The impact of the resulting atmospheric pollution may have widespread effects on the health of the populations living in the affected regions. For this reason, the study of the airborne particles brought by the ash clouds must cover not only their concentrations expressed in μg/m3, but also their size, shape and chemical composition. Our results revealed that during the eruption days, some periods with a higher concentration of the coarse particles (between 2.5 and 10 µm) were observed. The sphericity (R1) and roughness (R2) parameters showed specific characteristics of the particles, suggesting long distance of their origin. Furthermore, an increase up to 4 times more in the At% of the elements K, Al, Ca, Na and Si, which characterize the felsic lava, was observed during the eruption period.

Adoption of NAMEA Air Emission Accounts in Hungary

Abstract: The current phenomena of accelerating climate change and global warming has urged scientists and policy makers to devise a comprehensive and reliable system to identify the main causes and sources of the adverse processes. NAMEA (National Accounting Matrix including Environmental Accounts”) developed by EUROSTAT has gained in popularity as it highlights the impacts of societal action on the environment by linking economic indicators to environmental material flows. The paper reports on the work done in the Hungarian Central Statistical Office to adopt and further develop the NAMEA system and demonstrates the crucial changes occurred in the emission of the major pollutants between 2000 and 2009 taking into consideration economic indicators.

Using GIS in the Assessment of Landscape visual quality: a Methodological Approach Applied to Piatra Neamt, Romania

Abstract: This study demonstrates the feasibility of using GIS in the assessment of landscape visual quality. Based on the digital elevation model achieved by processing the 1:5000 scale topographic plans, Viewshed analysis application was performed for 5 observation points of the territory, which were selected by objective criteria. We tried to quantify the landscape values of Piatra Neamt administrative territory through an objective analysis of the reality on the ground reflected from the observation points, taking into consideration also the human perception regarding these aspects (a hardly accepted domain by the scientific community). The analysis can lead to precise values of the landscape, yet the only element more difficult to quantify remains human perception. The application was possible starting from the mathematical interpretation of the landscape proposed by Neuray G. in 1987, but a great importance in achieving the expected results is held by the specific GIS techniques mentioned above. The main purpose is to highlight the landscape potential of the area of study, noting that this analysis can be applied to any other area.

Industrial landscape expansion and evolution in Bucharest’s District 4

Abstract: New urban and environment policies were drafted after 1990 for Bucharest as the Romanian capital city adapts from planned to market economy and reintegrates itself into the European community. As these policies are not from the start fully effective or take time to implement, large areas inside the city, corresponding to former industrial parks, enter a long process of decay. Residential development is making a heavy presence both inside and around the city. As a consequence of these phenomena, the urban and industrial landscape changes dramatically. The study assesses the industrial landscape evolution over time and space in District 4 of Bucharest using available maps for 1900–2010, GIS and field observation forms. Three distinct periods were delimited: 1900–1945 with incipient industrial activity, 1946–1990 when large industrial parks were developed and 1989 – present time, with deindustrialisation and land use change. Environmental problems related to industrial areas decay need to be addressed as the residential area is expanding and neighbours or replaces former industrial sites.
