El Jadida Beach (X: -8.5007116; Y: 33.2316326) is a sandy beach of low altitude that constitutes a kind of enclave located between the port of El Jadida and rocky outcrops. It is influenced by natural and anthropic factors, as well as the impact of tourism, particularly during the summer, when sand is used for amusement activities (Beach Ball competition). In order to follow the morphodynamic changes of this beach, we carried out a study on two different time scales: a fifty-five years (1963 – 2018) shoreline evolution study using aerial photos and satellite images based on GIS tools using the Digital Shoreline Analysis System (DSAS) and a two-years (2017–2019) morphological beach study using a Differential Global Positioning System (DGPS). According to the results obtained by the diachronic study, the beach studied showed erosion in its middle and an accumulation at these bulges. This result is due to the presence of the harbor breakwater to the NW and the rocky outcrops to the SE; acting as a barrier preventing the movement of sediments and the erosion in the middle can be explained by the reduction of the sediment supply from the Oued Oum Erabia and by the exposure of this part to the dominant swells and also the human activities like used the beach for amusement activities (Beach Ball competition and other). Beach profile observations results show accumulation in the subaerial beach and erosion in the lower part of the foreshore. The study on two different time scales adopted in this paper, allowed us to understand longshore and cross-shore sedimentary mobility.

Nowadays technologies are changing every day and with them all services and tools in cases of disaster situations increase. However some sectors such as emergency planning and response are still having difficulties to implement the new technologies. In our paper we will present idea on how new technologies in flood risk mapping visualization can give more options to the first responders and optimize their time for reaction. The test area is located in Armenia, where exist a special dam constructed for mining purposes. It is built in earthquake vulnerable area and we evaluate the risk of dam break at that location. The final results which are flood risk maps are implemented in specially developed open source web-GIS tool. This tool is applicable for decision making in operational room or any other first responder facilities.

Eastern part of "Krzywińsko-Osiecki" Landscape Protected Area is located in central part of Wielkopolska region. The land use of analyzed area is dominated by arable lands, smaller area is covered by forests. The aim of present study was to determine the current state of tourism development in Borek Wielkopolski and Piaski communes, as well as to evaluate the nature-cultural values of eastern part of "Krzywińsko-Osiecki" Landscape Protected Area. Afterwards the possibilities of tourism management were designed based on above mentioned analyses. For this purposes the calculation of tourist function's indexes, creation the map of valorization and the concept of tourism and recreation development with the aid of GIS tools were performed. The obtained results revealed, that tourist activity at Borek Wielkopolski and Piaski communes area is very low. However, eastern part of "Krzywińsko-Osiecki" Landscape Protected Area is characterized by a diversity of natural-landscape values. The proposed activities would influence on better recognition of natural values and increase of tourism attractiveness of analyzed area. Two tourist trails were proposed, as well as recreation development of water reservoir in Jeżewo and improvement of existing tourist infrastructure.

Witkowo commune is located in the eastern part of Wielkopolska region at Gniezno county. This is typical agricultural commune with some tourism infrastructure. The aim of the work was to evaluate of an existing tourism potential of Witkowo commune based on comparison analysis of indexes describing its tourism potential and other communes located in administration boundaries of the same county. For this purpose the multidimensional comparison analysis of synthetic measures was performed. Afterwards the concept of tourism potential enrichment was proposed based on aforementioned analysis. The obtained results revealed, that the highest synthetic measure was noted for Witkowo commune, where the highest tourism potential was observed. The lowest level was recorded for Niechanowo commune, which revealed the lowest values almost in every analysed group of indexes. The proposed tourist trail contributes to tourism enrichment potential of Witkowo commune. The trail goes through Powidzko-Bieniszewski Landscape Protected Area. This is in agreement to the goal of tourism management for the development of the tourism at a protected area with considering the protection rules and local features. Simultaneously the tourist trail designation does not disturb ecological balance and create consistent tourist infrastructure.

Usługi ekosystemów przyczyniają się do podnoszenia jakości życia mieszkańców miast i obszarów suburbialnych, co sprawia, że ich kwantyfikacja i przestrzenne rozmieszczenie jest istotne z punktu widzenia planowania przestrzennego. W pracy przedstawiono wyniki kartowania potencjału dostarczania dwóch wybranych usług ekosystemów dla skali sub-regionalnej na przykładzie miasta Wrocławia i gmin ościennych. Badanie dotyczy usług ekosystemów zaopatrujących (dostarczanie pożywienia) oraz regulacyjnych (regulacja klimatu globalnego poprzez zmniejszenie koncentracji gazów cieplarnianych).

The activities in name of tourist development in Wodzislaw poviat are the reason to evaluate the tourist land development. The evaluation was prepared on the basis of selected indexes characterizing the level of tourist infrastructure development. It considered: the number of lodgings per km2, the number of restaurants per km2, the amount of additional attractions per km2 and the density of tourist tracks. This database was analyzed by the use of GIS tools. Using GIS software allowed working with large databases and provided the possibility to create a graphic representation of the results. The level of tourist land development is diversified and depends on it function. The cities with the best developed tourist infrastructure are Wodzislaw Slaski, Radlin, Pszow, Rydultowy and town in Odra Valley: Olza, Bukow and Nieboczowy. Pszow, Gorzyce and Godow commons have the biggest density of tourist tracks.

Działania na rzecz rozwoju turystyki w powiecie wodzisławskim są powodem do oceny zagospodarowania turystycznego obszaru. Ocenę wykonano w oparciu o wybrane wskaźniki, charakteryzujące stopień rozwoju infrastruktury turystycznej. Uwzględniono: liczbę miejsc noclegowych/km2, liczbę lokali gastronomicznych/km2, liczbę atrakcji dodatkowych/km2 oraz gęstość szlaków turystycznych. Bazę danych o zapleczu noclegowym, gastronomicznym, atrakcjach towarzyszących i szlakach turystycznych poddano analizom przy użyciu narzędzi GIS. Wykorzystanie oprogramowania GIS umożliwiło pracę z dużymi bazami danych i pozwoliło na graficzną prezentację wyników. Stopień zagospodarowania turystycznego obszaru jest zróżnicowany i zależy od pełnionej przez niego funkcji. Najlepiej rozwiniętą bazę turystyczną posiadają miasta Wodzisław Śląski, Radlin, Pszów i Rydułtowy oraz miejscowości w Dolinie Odry: Olza, Buków i Nieboczowy. Największa gęstość szlaków turystycznych występuje w Pszowie oraz w gminach Gorzyce i Godów.
