Article Citation - WoS: 1Citation - Scopus: 1Super Citizens: the Power of Social Innovation in İzmir/Turkey(Routledge, 2025) Köse, Ş.; Velibeyoğlu, K.This study aims to define the characteristics of social innovators, measure the impact of social innovation, and investigate its effects on urban transformation in İzmir. The study is based on semi-structured interviews with 14 social innovators and conducted by adopting a conceptual framework. We identify the characteristics of ‘super citizens’ in the literature that can contribute to SI’s empowerment in cities. The first finding shows that these individuals are expected to have 8 characteristics: being an activist, a social entrepreneur, a mediator, having a wide network, organizing goal-oriented works, involving all actors in the process, producing new solutions focused on the subject and finally being able to keep up with the change. The second finding shows that they are the most important actors in sustaining urban development, and their projects have impacts on urban transformation from a city level to an international level. If the interaction mechanism between relevant actors is provided by the local government through the Penta-helix model, super citizens may become one of the primary stakeholders to promote SI and create a more sustainable urban development. © 2024 The European Association for the Advancement of the Social Sciences.Article Citation - WoS: 3Citation - Scopus: 5Groundwater in Local Development Strategies: Case of Izmir(IWA Publishing, 2018) Velibeyoğlu, Koray; Yazdani, Hamidreza; Baba, AlperThis study takes into account groundwater in local development strategies of Izmir, in which rapid and uneven development has occurred in recent decades. Therefore, resilience thinking is needed in the future development of the city-region. To this end, the paper aims to make an analysis of recently completed asset-based local development strategies for Izmir city towards water resiliency. The methodology has two main steps. Firstly, by using spatial interaction analysis of peninsula and river basins, potential vulnerabilities and risks are indicated. Secondly, a stratified model of strategy evaluation is conducted by scrutinizing the existing layered approaches. Then, these models were applied to all strategic decisions including water resources and indicated a high level of consistency to achieve sustainable and resilient use of blue-green infrastructure in the future of Izmir’s metropolitan area. Local assets, including water resources, are the backbone of future development of the Izmir city-region. Therefore, usage of local assets in a multi-level perspective of strategy development needs to be understood. The stratified model denotes that special emphasis should be given to different river basins in different levels. This study illustrates that synergy management is needed between different layers of local development strategies, in which the role of urban and rural households is of the utmost importance.Article Citation - WoS: 26Citation - Scopus: 31Groundwater Quality and Hydrogeochemical Properties of Torbali Region, Izmir, Turkey(Springer Verlag, 2008) Tayfur, Gökmen; Kırer, Tuğba; Baba, AlperThe large demand for drinking, irrigation and industrial water in the region of Torbalö (Izmir, Turkey) is supplied from groundwater sources. Almost every factory and farm has private wells that are drilled without permission. These cause the depletion of groundwater and limiting the usage of groundwater. This study investigates spatial and temporal change in groundwater quality, relationships between quality parameters, and sources of contamination in Torbali region. For this purpose, samples were collected from 10 different sampling points chosen according to their geological and hydrogeological properties and location relative to factories, between October 2001 and July 2002. Various physical (pH, temperature, EC), chemical (calcium, magnesium, potassium, sodium, chloride, alkalinity, copper, chromium, cadmium, lead, zinc) and organic (nitrate, nitrite, ammonia, COD and cyanide) parameters were monitored. It was observed that the groundwater has bicarbonate alkalinity. Agricultural contamination was determined in the region, especially during the summer. Nitrite and ammonia concentrations were found to be above drinking water standard. Organic matter contamination was also investigated in the study area. COD concentrations were higher than the permissible limits during the summer months of the monitoring period.Article Citation - Scopus: 2Impacts of Transportation Projects on Urban Trends in Izmir(Turkish Chamber of Civil Engineers, 2008) Duvarcı, Yavuz; Selvi, Ömer; Günaydın, Hüsnü Murat; Gür, GüneşThe effects of major transportation projects on urban trends in Izmir were analyzed using the Delphi method. Once convergence was maintained in expert opinions, the Delphi results were re-evaluated according to the suggested method of total evaluation for obtaining much concise and general results. Accordingly, Absolute Total Impacts (ATI), Net Total Impacts (NTI) and the impact levels in broader terms were defined. The most effective projects were found to be: Integrated Rail Transportation System, Enhancement of Existing İzmir Port. The most impacted trends were: Development in Tourism Sector, Economic Development, Air Pollution and the Ratio of Private Car Ownership.Article Citation - WoS: 303Citation - Scopus: 336A Health Risk Assessment for Exposure To Trace Metals Via Drinking Water Ingestion Pathway(Elsevier Ltd., 2009) Kavcar, Pınar; Sofuoğlu, Aysun; Sofuoğlu, Sait CemilA health risk assessment was conducted for exposure to trace metals via drinking water ingestion pathway for Province of İzmir, Turkey. Concentrations of 11 trace metals were measured in drinking waters collected from 100 population weighted random sampling units (houses). The samples were analyzed in atomic absorption spectrometry for arsenic, and inductively coupled plasma-optical emission spectrometry for Be, Cd, Co, Cr, Cu, Mn, Ni, Pb, V, and Zn. Questionnaires were administered to a participant from each sampling unit to determine drinking water consumption related information and demographics. Exposure and risks were estimated for each individual by direct calculation, and for İzmir population by Monte Carlo simulation. Six trace metals (As, Cr, Cu, Mn, Ni, and Zn) were detected in >50% of the samples. Concentrations of As and Ni exceeded the corresponding standards in 20% and 58% of the samples, respectively. As a result, arsenic noncarcinogenic risks were higher than the level of concern for 19% of the population, whereas carcinogenic risks were >10-4 for 46%, and >10-6 for 90% of the population.
