Monitoring and detection of seawater intrusion in coastal aquifers in Croatia are one of the water management measures that attempt to notice an increase in salinity in time. Bokanjac-Poličnik is the coastal aquifer in Croatia that is at the risk of seawater intrusion. In that area, analysis of hydro-chemical indicators will be conducted due to the occasional seawater intrusion that occurs on wells that are included in the water supply system for the City of Zadar and surrounding villages. Due to the increased exploitation during the tourism season in summer and climate changes, salinization process is more intense. The presented results indicate that two of four wells on the case study area are under the influence of salt marine water.

Moped-style scooters are one of the most popular systems of micro-mobility. They are undoubtedly good for the city, as they promote forms of environmentally-friendly mobility, in which flexibility helps prevent traffic build-up in the urban centers where they operate. However, their increasing numbers are also generating conflicts as a result of the bad behavior of users, their unwarranted use in public spaces, and above all their parking. This paper proposes a methodology for finding parking spaces for shared motorcycle services using Geographic information system (GIS) location-allocation models and Global Positioning System (GPS) data. We used the center of Madrid and data from the company Muving (one of the city’s main operators) for our case study. As well as finding the location of parking spaces for motorbikes, our analysis examines how the varying distribution of demand over the course of the day affects the demand allocated to parking spaces. The results demonstrate how reserving a relatively small number of parking spaces for scooters makes it possible to capture over 70% of journeys in the catchment area. The daily variations in the distribution of demand slightly reduce the efficiency of the network of parking spaces in the morning and increase it at night, when demand is strongly focused on the most central areas.

Planning Problems

Traffic problems in the urban areas are increasing at a rapid rate. Engineers, planners or the policymakers are having a tough time in dealing with their multiple constraints for getting the desired solution. Some of the main transportation planning problems are mixed traffic plying on the roads, inadequate parking areas, increasing number of vehicles and road users, the unbalanced pattern of land use with obsolete road system, increasing number of road facilities and environmental pollution. Since in India most of the cities are unplanned, we are only left with an option management of existing infrastructure. In this paper, one such case study is presented in which a detailed traffic management for the city of Dharwad is carried out.

Indigenous Group

This paper has examined the way the Surels, an indigenous group inhabiting in Suri village of Dolakha district, perceive climate change and also has attempted to document their adaptive strategies to the changes brought about by climate change and global warming. These peoples have developed uniquely insightful ways of observing, interpreting, and responding to the impacts of climate changes through interacting and closely linking their lives with their surroundings. They clearly linked climate change with the changes in the weather patterns over the years indicating erratic rainfall patterns, advancing monsoon, advancing summer and spring, shorter and warmer winter, drier and hotter summer. This paper argues that these people observe and encounter climate and environmental changes immediately and use traditional knowledge and survival skills to adapt to these changes as they occurred. They have devised, though it is not well documented, useful coping mechanisms—modifying cropping pattern and crop types, community-based afforestation and forest management initiatives, improve water management, involvement of community organization in water management and seasonal migration to India- to respond and reduce climate induced risks and impacts which have enabled them to achieve stable livelihoods in their environment.

AbstractFrom a political point of view, 3rd century BCE Athens represents a shattered unity. Parts of the Athenian countryside and even the city itself were occupied by foreign troops. This loss of control affected the city’s political, economic, social, cultural, and religious life. Since Cleisthenic times, relations between political units and religious communities had become institutionalised through specific cults. Other cult places of relevance to the larger community and therefore with a catchment area that exceeded a deme, e.g. Eleusis, were also affected, as they lay within the occupied territories. This partial inaccessibility of the countryside risked the disruption of religious duties. The project “Cult and Crisis: The Sacred Landscape of Attica and its Correlation to Political Topography” aims to identify potentially affected cult places with no limitations regarding their possible catchment area by analysing their placement in relation to foreign military bases. Alterations in cult practice can plausibly be detected in changes ranging from cessation to the rerouting of ritual movement or the establishment of substitute cult places. As these “solutions” rarely feature in written sources, our GIS-based approach will focus on material remains from sanctuaries. Although an object’s use for ritual practice cannot be deduced with certainty, the distribution of finds certainly attests to human activity. This contribution presents a trial of this approach, taking the Sounion area as its case study.

Hydrochemical Types

Seawater intrusion problems are recorded in coastal aquifers, which constitute the main sources of drinking water and agricultural irrigation in many countries. The aim of this work is to describe the evolution of the salinity distribution by seawater intrusion, based on results from chemical analyses, of 29 groundwater samples in the NWAchaia area (Peloponnesus, Greece). The study of these data indicates that aquifer waters in large part of area reflect salinization related to seawater intrusion. The occurrence of Ca-CI hydrochemical types of groundwater indicates active seawater intrusion. Cation exchange is the most noticeable hydrogeochemical process in the movement of the saline front in the coastal aquifer. Geographical distribution of Careact index was mapped. The areas with advance or decline of the seawater intrusion front are defined from this map.
