TY - JOUR A1 - Yaka, Özge T1 - Gender and framing BT - gender as a main determinant of frame variation in Turkey's anti-hydropower movement JF - Women's Studies International Forum N2 - Framing literature has so far failed to construct gender as an analytical category that shapes the ways in which we perceive, identify and act upon grievances. This article builds on the insights of feminist theory and employs the conceptual vocabulary of the social movement framing perspective in maintaining gender as a main parameter of framing processes. Drawing on ethnographic research on local community struggles against hydropower plants in the Eastern Black Sea Region of Turkey, this article maintains the centrality of gender to framing processes. It analyzes the gendered difference between men’s macro-framings and women’s cultural and socio-ecological framings, which is rooted in their differing relationships with their immediate environment, as well as with the state and its institutions. The article maintains that the framings of women, which represent the immediacy of the environment, are more effective in gaining public support and shaping movement outcomes. In this sense, constructing gender as an important determinant of “frame variation” is essential not only to reveal women’s frames that are largely silenced through and within the mechanisms of social movement organization, but also to stress their centrality in shaping repertoires of contention, public reception and movement outcomes.

Based on extensive fieldwork on local community struggles against small-scale run-of river hydropower plants in Turkey, it expands the justice frame of environmental justice scholarship by going beyond the established conceptions of environmental justice as distribution - of environmental hazards and benefits, recognition and representation. Drawing on ethnographical fieldwork conducted in the East Black Sea region of Turkey, the article introduces the notion of socio-ecological justice to translate the relationality of the social and the ecological, of human life and non-human world, to the vocabulary of justice. It aims to extend the strictly humanist borders of social justice by maintaining that our intrinsic and intimate relations with the non-human world are an essential part of our well-being, and central to our needs to pursue a fair, decent life. It also seeks to contribute to the broader debate to facilitate a 'progressive composition' o f a common, more-than-human world. N2 - Durch die Einführung des Begriffs der sozio-ökologischen Gerechtigkeit will dieser Artikel die Beziehung zwi-schen Umwelt und Gerechtigkeit vertiefen, die von der Bewegung sowie seitens der Wissenschaft für die ‚Umwelt-gerechtigkeit‘ bereits fest etabliert wurde. Auf der Grundlage umfangreicher Feldforschungen zu den Kämpfen lokaler Gemeinschaften gegen kleine Laufwasserkraftwerke in der Türkei erweitert er den Gerechtigkeitsrah-men der Umweltgerechtigkeitsforschung, indem er über die etablierten Vorstellungen von Umweltgerechtigkeit als Verteilung – von Umweltgefahren und -nutzen, Anerkennung und Repräsentation – hinausgeht. Ausgehend von ethnographischen Feldforschungen, die in der Ost-Schwarzmeer-Region der Türkei durchgeführt wurden, führt der Artikel den Begriff der sozio-ökologischen Gerechtigkeit ein, um die Relationalität des Sozialen und des Ökologischen, des menschlichen Lebens und der nicht-menschlichen Welt in das Vokabular der Gerechtigkeit zu übersetzen. Er zielt darauf ab, die streng humanistischen Grenzen der sozialen Gerechtigkeit zu erweitern, indem er behauptet, dass unsere intrinsischen und intimen Beziehungen mit der nichtmenschlichen Welt ein we-sentlicher Bestandteil unseres Wohlergehens und von zentraler Bedeutung für unsere Bedürfnisse nach einem fairen, menschenwürdigen Leben sind. Er versucht auch, einen Beitrag zur breiteren Debatte zu leisten, um eine ‚progressive Zusammensetzung‘ einer gemeinsamen, mehr als menschlichen Welt zu erleichtern.

Each participant read three short case scenarios (vignettes) and completed items pertaining to the female victim and male perpetrator. The vignettes were systematically varied with regard to the type of crime that was committed (rape or robbery), the perpetrator’s coercive strategy (physical force or exploiting the victim’s alcohol-induced defenselessness), and the victim-perpetrator relationship prior to the incident (stranger, acquaintance, or ex-partner). Furthermore, participant gender and acceptance of rape myths (beliefs that justify or trivialize sexual violence) were taken into account. One half of the participants completed the rape myth acceptance (RMA) scales first and then received the vignettes, while the other half were given the vignettes first and then completed the RMA scales. As expected, more blame was attributed to victims of rape than to victims of robbery. Conversely, perpetrators of rape were blamed less than perpetrators of robbery. The more participants endorsed rape myths, the more blame was attributed to the victim and the less blame was attributed to the perpetrators. Increasing levels of RMA were associated with an increase in victim blame (VB) in both rape and robbery cases, but the increase in rape VB was significantly more pronounced than in robbery VB. Increasing RMA was associated with an attenuation of perpetrator blame (PB) that was more pronounced for rape than for robbery cases, but the difference was not significant. As expected, victims of rape were blamed more when the perpetrator exploited their defenselessness due to alcohol intoxication than when they were overpowered by physical force. Contrary to the hypothesis, this was also true for robbery victims. Rape victims who knew their attacker (ex-partner or acquaintance) were blamed more than victims who were assaulted by strangers. Contrary to the hypothesis, robbery victims who were assaulted by an ex-partner were blamed more than acquaintance or stranger robbery victims. As predicted, the closer the relationship between victim and perpetrator, the less blame was attributed to perpetrators of rape while this factor had no effect on PB in robbery cases. Men compared to women attributed more blame to the victims and less blame to the perpetrators. As expected, these gender differences in blame attributions were partially mediated by gender differences in RMA: After RMA was taken into account, the gender differences disappeared nearly completely for VB and were significantly reduced in PB. The order of presentation of the vignettes and the RMA measures was systematically varied to test the causal influence of RMA on rape blame attributions. The hypothesis that RMA causes VB and PB in rape cases (as opposed to the other way around or both are caused by a third variable) was not supported. Possible reasons for this failed manipulation and its implications for the mediation model are discussed. With regard to blame attribution in rape cases, the present results match what was expected from previous studies which were mainly conducted in “Western” countries like the United States, the United Kingdom, or Germany. The present results support the notion that the victim-perpetrator relationship and the victim’s alcohol consumption are cross-culturally stable factors for blame attribution in rape cases. It was expected that blame attribution in robbery cases would be unaffected by the perpetrator’s coercive strategy and the victim-perpetrator relationship, but the results were inconsistent. One unexpected effect is particularly noteworthy: When the perpetrator used physical force, more blame was attributed to rape than to robbery victims, but intoxicated victims were blamed more and almost equally so for both types of crime. Perpetrators who exploited drunk victims were blamed less in both rape and robbery cases. These results contradict German results collected with the German version of the same instruments (Bieneck & Krahé, 2011). Turkey is a Muslim country and alcohol is surrounded by a certain taboo. Possibly, the results reflect a cultural difference in that intoxicated victims are generally blamed more for their victimization and this factor is not limited to rape cases. N2 - Die vorliegende Arbeit untersuchte die Verantwortungszuschreibung zu Opfern und Tätern von Vergewaltigung im Vergleich zu Raub in der Türkei. Die Versuchspersonen lasen jeweils drei Vignetten, d.h. kurze Beschreibungen von hypothetischen Raub- und Vergewaltigungsfällen, und wurden im Anschluss an jede Vignette gebeten, die Verantwortung des weiblichen Opfers und des männlichen Täters für den Vorfall zu beurteilen. Die Vignetten variierten systematisch auf den Variablen Art des Verbrechens (Vergewaltigung oder Raub), Täterstrategie (physische Gewalt oder Ausnutzen der Wehrlosigkeit des betrunkenen Opfers) und der Opfer-Täter-Beziehung vor der Tat (Fremder, Bekannter oder Ex-Partner). Zusätzlich wurde die Vergewaltigungsmythenakzeptanz (VMA) der Versuchspersonen erhoben sowie deren Geschlecht als Faktor berücksichtigt. Vergewaltigungsmythen beschreiben Einstellungen, die sexualisierte Gewalt bagatellisieren, indem z.B. Opfern Schuld an der Tat zugeschrieben wird (Victim Blaming) oder die Täter entschuldigt werden. Die Hälfte der Versuchspersonen erhielt zunächst die Skalen zur VMA und bearbeitete im Anschluss daran die Vignetten. Die andere Hälfte der Versuchspersonen bearbeitete die Materialien in umgekehrter Reihenfolge, also zunächst die Vignetten und danach die VMA-Skalen. Wie erwartet wurde den Opfern von Vergewaltigung mehr Verantwortung für die Tat zugeschrieben als Opfern von Raub. Umgekehrt wurde den Tätern von Vergewaltigung weniger Verantwortung zugeschrieben als Tätern von Raub. Je höher die VMA, desto mehr wurde das Opfer und desto weniger wurde der Täter für die Tat verantwortlich gemacht. Mit steigender VMA stieg die Verantwortungszuschreibung an Opfer beider Verbrechen an, aber der Zuwachs in der Schuldzuschreibung war signifikant stärker ausgeprägter in Vergewaltigungsfällen als in Raubfällen. Mit steigender VMA sank die Schuldzuschreibung an den Täter in Vergewaltigungsfällen stärker als in Raubfällen, der Unterschied war aber nicht signifikant. Wie erwartet wurde Opfern von Vergewaltigung mehr Schuld zugeschrieben, wenn sie betrunken waren als wenn sie vom Täter überwältigt wurden. Entgegen der Hypothese traf dies auch für Raubfälle zu. Vergewaltigungsopfern, die ihren Täter kannten, wurde mehr Schuld zugeschrieben als denen, die von einem Fremden vergewaltigt wurden. Entgegen der Hypothese wurde Raubopfern, die von einem Ex-Partner überfallen wurden, ebenfalls mehr Schuld an der Tat gegeben im Vergleich zu Raubfällen, die von Fremden oder Bekannten begangen wurden. Wie vorhergesagt wurde Vergewaltigern weniger Schuld zugeschrieben je enger die Opfer-Täter-Beziehung, während die Schuldzuschreibung an Raubtätern nicht von ihrer Beziehung zum Opfer beeinflusst wurde. Männer im Vergleich zu Frauen wiesen den Opfern von Vergewaltigung mehr Schuld zu und den Tätern weniger. Wie erwartet wurden die Geschlechtsunterschiede in Bezug auf Schuldzuschreibungen an das Opfer und den Täter teilweise durch Geschlechtsunterschiede in VMA vermittelt: Nach Berücksichtigung von VMA zeigten sich in Bezug auf Opfer-Schuld keine Geschlechtsunterschiede mehr und in Bezug auf Täter-Schuld nur noch geringe. Die systematische Variation der Reihenfolge von Vignetten und VMA hatte zum Ziel, die kausale Wirkung von VMA auf Schuldzuschreibungen an Opfer und Täter von Vergewaltigung zu testen. Die Hypothese, dass VMA Schuldzuschreibungen an Opfer und Täter auslöst (im Vergleich zum umgekehrten Fall oder dass beide Variablen von einer dritten Variable ausgelöst werden) konnte nicht bestätigt werden. Mögliche Gründe für dieses Ergebnis sowie Implikationen für die Mediationsanalyse werden diskutiert. In Bezug auf die Vergewaltigungsfälle entsprechen die Ergebnisse dem, was aufgrund früherer Studien erwartet wurde. Der Großteil früherer Studien wurde in „westlichen“ Ländern wie den Vereinigten Staaten, dem Vereinigten Königreich oder Deutschland durchgeführt. Die vorliegenden Ergebnisse aus der Türkei stützen daher die Annahme, dass Opfer-Täter-Beziehung und Alkoholkonsum des Opfers interkulturell stabile Faktoren für die Verantwortungszuschreibung in Vergewaltigungsfällen sind. Die Ergebnisse in Bezug auf die erwartete Unterscheidung zwischen Raub- und Vergewaltigungsfällen blieben allerdings inkonsistent. Ein Effekt ist besonders hervorzuheben: Wenn der Täter Gewalt anwendete, wurde den Opfern von Vergewaltigung mehr Schuld an der Tat gegeben als Opfern von Raub. Wenn das Opfer betrunken war, haben Beurteiler nicht zwischen Opfern von Raub und Vergewaltigung unterschieden. Tätern, die alkoholisierte Opfer ausnutzten, wurde sowohl in Raub- als auch Vergewaltigungsfällen weniger Schuld zugeschrieben. Diese Ergebnisse stehen im Widerspruch zu Ergebnissen aus Deutschland, die mit den gleichen Instrumenten (in deutscher Fassung) erhoben wurden (Bieneck & Krahé, 2011). Die Türkei ist muslimisch geprägt und Alkohol unterliegt einem gewissen Tabu. Möglicherweise zeigt sich hier ein kultureller Unterschied, dass alkoholisierten Opfern im Allgemeinen mehr Schuld zugeschrieben wird und dieser Faktor nicht nur speziell Vergewaltigungsfälle betrifft.

Little evidence is available from non-Western countries, especially from Muslim societies. The purpose of the present article was to provide a first systematic review of the studies examining the prevalence of sexual aggression in Turkey, including both victimization and perpetration reports from women and men. Additionally, differences in prevalence rates depending on relationship constellations and characteristics of victims and perpetrators were reviewed. By a two-stage literature search, 56 studies were identified for inclusion. All studies examined sexual victimization of women, only four studies included sexual victimization of men. Data on sexual aggression perpetration were extremely limited, with only two studies providing prevalence rates. Prevalence rates of sexual victimization were found to vary greatly, which may be attributed to a lack of methodological and conceptual consistency across studies. Likewise, no consistent picture was revealed for victims' or perpetrators' sociodemographic or situational characteristics associated with differences in prevalence rates. We discuss reasons for the variability in prevalence rates and outline recommendations for future research.

As predicted, risky sexual scripts were linked to higher odds of perpetration through more risky sexual behavior cross-sectionally in both the Chilean and the Turkish sample and indirectly predicted perpetration 12 months later. High sexual self-esteem increased the likelihood of perpetration via higher initiation assertiveness in the Turkish sample only. High religiosity reduced the odds of perpetration through less risky sexual scripts and less risky sexual behavior in both samples. In addition, high religiosity increased the probability of perpetration through lower sexual self-esteem in the Turkish sample. Implications of these findings and the role of cultural factors contributing to the differential functioning of religiosity and sexual self-esteem are discussed.

The first aim of this research project was to systematically review the available evidence provided by past studies on this topic within each country. The second aim was to empirically study the prevalence of experiencing and engaging in sexual aggression since the age of consent among college students in Chile and Turkey. The third aim was to conduct cross-cultural analyses examining pathways to victimization and perpetration based on a two-wave longitudinal design. Methods: This research adopted a gender-inclusive approach by considering men and women in both victim and perpetrator roles. For the systematic reviews, multiple-stage literature searches were performed, and based on a predefined set of eligibility criteria, 28 studies in Chile and 56 studies in Turkey were identified for inclusion. A two-wave longitudinal study was conducted to examine the prevalence and predictors of sexual aggression among male and female college students in Chile and Turkey. Self-reports of victimization and perpetration were assessed with a Chilean Spanish or Turkish version of the Sexual Aggression and Victimization Scale. Two path models were conceptualized in which participants’ risky sexual scripts for consensual sex, risky sexual behavior, sexual self-esteem, sexual assertiveness, and religiosity were assessed at T1 and used as predictors of sexual aggression victimization and perpetration at T2 in the following 12 months, mediated through past victimization or perpetration, respectively. The models differed in that sexual assertiveness was expected to serve different functions for victimization (refusal assertiveness negatively linked to victimization) and perpetration (initiation assertiveness positively linked to perpetration). Results: Both systematic reviews revealed that victimization was addressed by all included studies, but data on perpetration was severely limited. A great heterogeneity not only in victimization rates but also in predictors was found, which may be attributed to a lack of conceptual and methodological consistency across studies. The empirical analysis of the prevalence of sexual aggression in Chile revealed a victimization rate of 51.9% for women and 48.0% for men, and a perpetration rate of 26.8% for men and 16.5% for women. In the Turkish original data, victimization was reported by 77.6% of women and 65.5% of men, whereas, again, lower rates were found for perpetration, with 28.9% of men and 14.2% of women reporting at least one incident. The cross-cultural analyses showed, as expected, that risky sexual scripts informed risky sexual behavior, and thereby indirectly increased the likelihood of victimization and perpetration at T2 in both samples. More risky sexual scripts were also linked to lower levels of refusal assertiveness in both samples, indirectly increasing the vulnerability to victimization at T2. High sexual self-esteem decreased the probability of victimization at T2 through higher refusal assertiveness as well as through less risky sexual behavior also in both samples, whereas it increased the odds of perpetration at T2 via higher initiation assertiveness in the Turkish sample only. Furthermore, high religiosity decreased the odds of perpetration and victimization at T2 through less risky sexual scripts and less risky sexual behavior in both samples. It reduced the vulnerability to victimization through less risky sexual scripts and higher refusal assertiveness in the Chilean sample only. In the Turkish sample only, it increased the odds of perpetration and victimization through lower sexual self-esteem. Conclusions: The findings showed that sexual aggression is a widespread problem in both Chile and Turkey, contributing cross-cultural evidence to the international knowledge base and indicating the clear need for implementing policy measures and prevention strategies in each country. Based on the results of the prospective analyses, concrete implications for intervention efforts are discussed. N2 - Hintergrund: Obwohl sexuelle Aggression als ein ernstzunehmendes Problem weltweit angesehen wird, stützt sich die gegenwärtige Datenlage in erster Linie auf Evidenz westlicher Staaten. Für die vorliegende Arbeit wurden die Länder Chile und Türkei anhand theoretischer Überlegungen ausgewählt, um sowohl die Prävalenz als auch Prädiktoren sexueller Aggression zu untersuchen. Das erste Ziel bestand darin, die Ergebnisse früherer Studien zu sexueller Aggression in jedem Land systematisch zu betrachten. Das zweite Ziel war, die Prävalenz von Viktimisierung und Ausübung sexueller Aggression seit dem Schutzalter unter Studierenden in Chile und der Türkei empirisch zu untersuchen. Das dritte Ziel war schließlich die Durchführung von interkulturellen Analysen, um Pfade zu Viktimisierung und Ausübung anhand eines längsschnittlichen Designs zu überprüfen. Methode: Es wurde ein geschlechterinklusiver Ansatz verfolgt, wobei Männer und Frauen sowohl als potentielle Opfer als auch Täter*innen betrachtet wurden. Für die systematischen Reviews wurden mehrstufige Literaturrecherchen durchgeführt. Basierend auf einem vordefinierten Satz an Auswahlkriterien wurden insgesamt 28 Studien für Chile und 56 Studien für die Türkei identifiziert. Weiterhin wurde eine Längsschnittstudie mit zwei Messzeitpunkten durchgeführt, um sowohl die Prävalenz als auch Prädiktoren sexueller Aggression unter Studierenden in Chile und der Türkei zu untersuchen. Selbstberichte über Viktimisierung und Ausübung sexueller Aggression wurden mittels einer spanischen bzw. türkischen Version der Sexual Aggression and Victimization Scale erhoben. Zwei Pfadmodelle wurden konzipiert, in denen riskante Skripts für konsensuelle Sexualkontakte, riskantes Sexualverhalten, sexuelles Selbstwertgefühl, sexuelle Assertivität und Religiosität zu T1 erfasst wurden und als Prädiktoren für Viktimisierung und Ausübung sexueller Aggression in den folgenden 12 Monaten (T2) verwendet wurden, jeweils mediiert durch vergangene Viktimisierung bzw. Ausübung sexueller Aggression. Die Modelle unterschieden sich darin, dass für sexuelle Assertivität unterschiedliche Funktionen für Viktimisierung (Ablehnungsassertivität negativ mit Viktimisierung assoziiert) und Ausübung sexueller Aggression (Initiierungsassertivität positiv mit Ausübung assoziiert) angenommen wurden. Ergebnisse: Die beiden Reviews zeigten, dass Viktimisierung von allen berücksichtigten Studien untersucht wurde, wohingegen kaum Daten zur Ausübung von sexueller Aggression vorlagen. Eine große Heterogenität wurde bei den Viktimisierungsraten, aber auch bei den Prädiktoren festgestellt, was vor allem auf mangelnde konzeptionelle und methodische Konsistenz zwischen den Studien zurückgeführt werden kann. In Bezug auf die Originaldaten zur Prävalenz in Chile zeigte sich, dass 51.9% der Frauen und 48.0% der Männer Viktimisierung angaben. Die Prävalenzraten zur Ausübung lagen bei 26.8% unter Männern und 16.5% unter Frauen. In den türkischen Originaldaten wurde Viktimisierung von 77.6% der Frauen und 65.5% der Männer berichtet. Niedigere Raten wurden erneut für die Ausübung gefunden: 28.9% der Männer und 14.2% der Frauen in der Türkei gaben mindestens einen sexuell aggressiven Übergriff an. Die interkulturellen Analysen zeigten, dass riskante sexuelle Skripts mit einem riskanteren Sexualverhalten assoziiert waren und dadurch indirekt die Wahrscheinlichkeit von Viktimisierung und Ausübung zu T2 in beiden Stichproben erhöhten. Riskantere sexuelle Skripts waren weiterhin mit einer geringeren Ablehnungsassertivität in beiden Stichproben assoziiert, was die Vulnerabilität für Viktimisierung zu T2 indirekt erhöhte. Höheres sexuelles Selbstwertgefühl verringerte die Wahrscheinlichkeit sexueller Viktimisierung zu T2 durch eine höhere Ablehnungsassertivität sowie durch weniger riskantes Sexualverhalten in beiden Stichproben, wohingegen die Wahrscheinlichkeit für Ausübung zu T2 durch eine höhere Initiierungsassertivität größer wurde, allerdings nur in der türkischen Stichprobe. Darüber hinaus verminderte höhere Religiosität die Wahrscheinlichkeit von Viktimisierung und Ausübung zu T2 über weniger riskante sexuelle Skripts und weniger riskantes Sexualverhalten in beiden Stichproben. In der chilenischen Stichprobe wurde die Vulnerabilität für Viktimisierung durch weniger riskante sexuelle Skripts und höhere Ablehnungsassertivität verringert. Hingegen erhöhte sich in der türkischen Stichprobe die Wahrscheinlichkeit für Viktimisierung und Ausübung durch ein niedrigeres sexuelles Selbstwertgefühl. Konklusion: Die Ergebnisse zeigen, dass sexuelle Aggression sowohl in Chile als auch in der Türkei ein weit verbreitetes Problem darstellt. Sie bereichern die internationale Wissensbasis mit interkultureller Evidenz und weisen auf die Notwendigkeit hin, politische Maßnahmen und Präventionsstrategien zu implementieren. Basierend auf den Ergebnissen der prospektiven Analysen werden konkrete Implikationen für Interventionsstrategien diskutiert.

Thirteen large calc-alkaline ignimbrite sheets form marker bands within the volcano-sedimentary succession (the Urgup Formation) and provide a robust chronostratigraphy for paleoecologic evaluation of the interleaved paleosols. This paper evaluates the chronologic record in the context of the radiometric, magnetostratigraphic and lithostratigraphic controls. Previous inconsistencies relating primarily to K/Ar evidence were reason for the initiation of an integrated study which includes Ar-40/Ar-39 dating, palaeomagnetic and stratigraphic evidence. The newly determined Ar-40/Ar-39-ages (Lepetit, 2010) are in agreement with Ar/Ar and U/Pb data meanwhile published by Pauquette and Le Pennec (2012) and Aydar et al. (2012). The Ar-40/Ar-39-ages restrict the end of the Urgup Formation to the late Miocene. The paleosol sequence enclosed by the ignimbrites is thus restricted to the late Miocene, the most intense formation of pedogene calcretes correlating with the Messinian Salinity Crisis.

The potential triggering mechanisms (i.e., atmospheric circulations and precipitation amounts) and aggravating pathways (i.e., topographic features, catchment size, land use types, and soil properties) of these 25 events were analyzed. On this basis, a new approach was developed to identify the main influencing factor per event and to provide additional information for determining the dominant flood occurrence pathways for severe floods. The events were then classified through hierarchical cluster analysis. As a result, six different clusters were found and characterized. Cluster 1 comprised flood events that were mainly influenced by drainage characteristics (e.g., catchment size and shape); Cluster 2 comprised events aggravated predominantly by urbanization; steep topography was identified to be the dominant factor for Cluster 3; extreme rainfall was determined as the main triggering factor for Cluster 4; saturated soil conditions were found to be the dominant factor for Cluster 5; and orographic effects of mountain ranges characterized Cluster 6. This study determined pathway patterns of the severe floods in Turkey with regard to their main causal or aggravating mechanisms. Accordingly, geomorphological properties are of major importance in large catchments in eastern and northeastern Anatolia. In addition, in small catchments, the share of urbanized area seems to be an important factor for the extent of flood impacts.

Accordingly, a methodology based on experiences from developing countries was proposed by the United Nations Office for Disaster Risk Reduction (UNDRR) to estimate direct economic losses on the macro-scale. Since Turkey also signed the SFDRR, we aimed to adapt, validate and apply the loss estimation model proposed by the UNDRR in Turkey for the first time. To do so, the well-documented flood event in Mersin of 2016 was used to calibrate the damage ratios for the agricultural, commercial and residential sectors, as well as educational facilities. Case studies between 2015 and 2020 with documented losses were further used to validate the model. Finally, model applications provided initial loss estimates for floods occurred recently in Turkey. Despite the limited event documentation for each sector, the calibrated model yielded good results when compared to documented losses. Thus, by implementing the UNDRR method, this study provides an approach to estimate the direct economic losses in Turkey on the macro-scale, which can be used to fill gaps in event databases, support the coordination of financial aid after flood events and facilitate monitoring of the progress toward and achievement of Global Target C of the Sendai Framework for Disaster Risk Reduction 2015-2030.

Hence, dedicated action toward disaster risk reduction is needed to understand the underlying drivers and create efficient risk mitigation plans. Such action is requested by the Sendai Framework for Disaster Risk Reduction 2015-2030 (SFDRR), a global agreement launched in 2015 that establishes stating priorities for action, e.g. an improved understanding of disaster risk. Turkey is one of the SFDRR contracting countries and has been severely affected by many natural hazards, in particular earthquakes and floods. However, disproportionately little is known about flood hazards and risks in Turkey. Therefore, this thesis aims to carry out a comprehensive analysis of flood hazards for the first time in Turkey from triggering drivers to impacts. It is intended to contribute to a better understanding of flood risks, improvements of flood risk mitigation and the facilitated monitoring of progress and achievements while implementing the SFDRR. In order to investigate the occurrence and severity of flooding in comparison to other natural hazards in Turkey and provide an overview of the temporal and spatial distribution of flood losses, the Turkey Disaster Database (TABB) was examined for the years 1960-2014. The TABB database was reviewed through comparison with the Emergency Events Database (EM-DAT), the Dartmouth Flood Observatory database, the scientific literature and news archives. In addition, data on the most severe flood events between 1960 and 2014 were retrieved. These served as a basis for analyzing triggering mechanisms (i.e. atmospheric circulation and precipitation amounts) and aggravating pathways (i.e. topographic features, catchment size, land use types and soil properties). For this, a new approach was developed and the events were classified using hierarchical cluster analyses to identify the main influencing factor per event and provide additional information about the dominant flood pathways for severe floods. The main idea of the study was to start with the event impacts based on a bottom-up approach and identify the causes that created damaging events, instead of applying a model chain with long-term series as input and searching for potentially impacting events as model outcomes. However, within the frequency analysis of the flood-triggering circulation pattern types, it was discovered that events in terms of heavy precipitation were not included in the list of most severe floods, i.e. their impacts were not recorded in national and international loss databases but were mentioned in news archives and reported by the Turkish State Meteorological Service. This finding challenges bottom-up modelling approaches and underlines the urgent need for consistent event and loss documentation. Therefore, as a next step, the aim was to enhance the flood loss documentation by calibrating, validating and applying the United Nations Office for Disaster Risk Reduction (UNDRR) loss estimation method for the recent severe flood events (2015-2020). This provided, a consistent flood loss estimation model for Turkey, allowing governments to estimate losses as quickly as possible after events, e.g. to better coordinate financial aid. This thesis reveals that, after earthquakes, floods have the second most destructive effects in Turkey in terms of human and economic impacts, with over 800 fatalities and US$ 885.7 million in economic losses between 1960 and 2020, and that more attention should be paid on the national scale. The clustering results of the dominant flood-producing mechanisms (e.g. circulation pattern types, extreme rainfall, sudden snowmelt) present crucial information regarding the source and pathway identification, which can be used as base information for hazard identification in the preliminary risk assessment process. The implementation of the UNDRR loss estimation model shows that the model with country-specific parameters, calibrated damage ratios and sufficient event documentation (i.e. physically damaged units) can be recommended in order to provide first estimates of the magnitude of direct economic losses, even shortly after events have occurred, since it performed well when estimates were compared to documented losses. The presented results can contribute to improving the national disaster loss database in Turkey and thus enable a better monitoring of the national progress and achievements with regard to the targets stated by the SFDRR. In addition, the outcomes can be used to better characterize and classify flood events. Information on the main underlying factors and aggravating flood pathways further supports the selection of suitable risk reduction policies. All input variables used in this thesis were obtained from publicly available data. The results are openly accessible and can be used for further research. As an overall conclusion, it can be stated that consistent loss data collection and better event documentation should gain more attention for a reliable monitoring of the implementation of the SFDRR. Better event documentation should be established according to a globally accepted standard for disaster classification and loss estimation in Turkey. Ultimately, this enables stakeholders to create better risk mitigation actions based on clear hazard definitions, flood event classification and consistent loss estimations. N2 - In den letzten Jahrzehnten verursachten Naturgefahren hohe humanitäre und wirtschaftliche Verluste, wobei viele dieser Ereignisse durch den Klimawandel verstärkt werden und einen zunehmenden Trend in Häufigkeit und Schwere aufweisen. Daher sind gezielte Verfahren zur Reduzierung von Katastrophenrisiken erforderlich, um zugrundeliegende Treiber zu verstehen und effektive Risikominderungspläne zu erstellen. Solche Verfahren werden durch das Sendai-Rahmenwerk für Katastrophenvorsorge 2015-2030 (SFDRR) eingefordert. Das SFDRR ist, ein internationales Rahmenwerk, das 2015 verabschiedet wurde und prioritäre Maßnahmen festlegt, z.B. eine Verbesserung der Wissensgrundlagen zum Katastrophenrisiko. Die Türkei ist eines der SFDRR-Vertragsländer und wurde in der Vergangenheit von vielen Naturgefahren, insbesondere Erdbeben und Überschwemmungen schwer getroffen. Über die Hochwassergefahren und -risiken in der Türkei ist jedoch vergleichsweise wenig bekannt. In dieser Arbeit wird daher zum ersten Mal eine umfassende Analyse der Hochwassergefahren in der Türkei durchgeführt, von den auslösenden Ursachen bis hin zu den Auswirkungen. Ziel ist es, das Verständnis über Hochwasserrisiken zu verbessern, Studien zur Minderung des Hochwasserrisikos anzuregen und das Monitoring der Fortschritte und Zielerreichung bei der Umsetzung des SFDRR zu erleichtern. Um das Auftreten und die Stärke von Überschwemmungen im Vergleich zu anderen Naturgefahren in der Türkei zu untersuchen und einen Überblick über die raumzeitliche Verteilung von Hochwasserschäden, wurde die Turkey Disaster Database (TABB) für den Zeitraum 1960 bis 2014 ausgewertet. Die TABB Datenbank wurde durch Vergleiche mit der Emergency Events Datenbank (EM-DAT), der Dartmouth Flood Observatory Datenbank, wissenschaftlicher Literatur und Nachrichtenarchive überprüft. Zudem wurden die stärksten Überschwemmungen zwischen 1960 und 2014 identifiziert. Diese bildeten die Basis für eine Analyse der Auslösemechanismen (bspw. atmosphärische Zirkulationsmuster und Niederschlagsmengen) und verstärkende Wirkungspfade (z.B. topographische Eigenschaften, Größe der Einzugsgebiete, Landnutzung und Bodeneigenschaften). Dafür wurde ein neues Verfahren entwickelt, und die Ereignisse wurden mithilfe von hierarchischen Clusteranalysen klassifiziert, um die Haupteinflussfaktoren pro Ereignis zu identifizieren und zusätzliche Informationen über die dominanten Wirkungspfade bei schweren Überschwemmungen bereitzustellen. Die grundlegende Idee dieser Arbeit bestand darin, bei den Ereignisauswirkungen als Bottom-up-Ansatz zu beginnen und die Ursachen für Schadensereignisse zu identifizieren, anstatt eine Modellkette mit Langzeitreihen als Eingabe anzuwenden und darin nach potenziellen Schadensereignissen zu suchen. Bei der Häufigkeitsanalyse von hochwasserauslösenden Zirkulationsmustern wurde jedoch festgestellt, dass einige schwer Niederschlagsereignisse nicht in der Liste der schwersten Hochwasserereignisse waren, d.h., ihre Auswirkungen waren nicht in nationalen und internationalen Schadensdatenbanken dokumentiert, wurden jedoch in Nachrichtenarchiven erwähnt und vom türkischen staatlichen Wetterdienst gemeldet. Dieses Erkenntnis stellt den Bottom-up-Modelansatz in Frage und unterstreicht die Dringlichkeit einer konsistenten Ereignis- und Schadensdokumentation. Daher wurde im nächsten Schritt gezielt das Schadenmodell der Vereinten Nationen für Katastrophenvorsorge (UNDRR) für kürzlich aufgetretene starke Flutereignisse (2015-2020) angepasst, validiert und angewendet. Damit wurde ein konsistentes Hochwasserschadenmodell für die Türkei bereitgestellt, das es den Behörden ermöglicht, Verluste so schnell wie möglich nach Ereignissen abzuschätzen, zum Beispiel um eine bessere Koordination von finanziellen Hilfen zu gewährleisten. Diese Arbeit zeigt, dass Überschwemmungen mit mehr als 800 Todesfällen und 885,7 Millionen US Dollar wirtschaftlichen Schaden zwischen 1960 und 2020 nach Erdbeben den zweit höchsten zerstörerischen Effekt in der Türkei in Bezug auf humanitäre und wirtschaftliche Auswirkungen haben. Daher sollte dieses Thema mehr Aufmerksamkeit auf nationaler Ebene erhalten. Die Cluster-Ergebnisse der dominanten hochwasser-auslösenden Mechanismen (z.B. Zirkulationsmuster, Starkniederschlag, plötzliche Schneeschmelze) erhalten wichtige Informationen zur Quell- und Pfad-Identifikation, welche als Basisinformation für Gefahren-identifikation in der vorläufigen Risikoeinschätzung dienen kann. Die Implementierung des UNDRR-Schadenmodells zeigt, dass das Modell mit länderspezifischen Parametern, kalibrierten Schadensgraden und ausreichender Ereignisdokumentation (d.h. physischer geschädigte Einheiten) empfohlen werden kann, um erste Schätzungen zur Höhe der direkten wirtschaftlichen Schäden bereitzustellen -- auch unmittelbar nach Eintreten von Ereignissen, da die Modellschätzungen im Vergleich mit dokumentierten Verlusten gut übereinstimmten. Die präsentierten Ergebnisse können dazu beitragen, die nationale Schadensdatenbank der Türkei zu verbessern, und somit ein besseres Monitoring der nationalen Fortschritte und Erfolge im Hinblick auf die Ziele des SFDRR ermöglichen. Zusätzlich können die Ergebnisse für eine bessere Charakterisierung und Klassifizierung von Hochwasserereignissen verwendet werden. Informationen zu den zugrundeliegenden Einflussfaktoren und verstärkenden Wirkungspfaden unterstützen die Auswahl geeigneter Risikomanagementstrategien. Alle Eingabevariablen dieser Arbeit wurden aus öffentlich verfügbaren Daten bezogen. Die Ergebnisse sind zugänglich und können für die weitere Forschung verwendet werden. Insgesamt konnte festgestellt werden, dass die konsistente Erfassung von Schadensdaten und eine bessere Ereignisdokumentation mehr Beachtung finden muss, um die Implementierung des SFDRR verlässlich zu überwachen. Bessere Ereignisdokumentationen sollten nach einem weltweit anerkannten Standard für Gefahrenklassifizierung und Schadensabschätzung in der Türkei etabliert werden. Letztendlich ermöglicht dies den Verantwortlichen auf Basis von eindeutigen Gefahrendefinitionen, Hochwasser-Ereignisklassifizierungen und konsistenten Schadenschätzungen bessere Maßnahmen zur Risikominderung zu erarbeiten.

JF - Natural hazards : journal of the International Society for the Prevention and Mitigation of Natural Hazards N2 - Turkey has been severely affected by many natural hazards, in particular earthquakes and floods. Especially over the last two decades, these natural hazards have caused enormous human and economic damage. Although there is a large body of literature on earthquake hazards and risks in Turkey, comparatively little is known about flood hazards and risks. Therefore, this study aims to investigate the severity of flooding in comparison with other natural hazards in Turkey and to analyse the flood patterns by providing an overview of the temporal and spatial distribution of flood losses. These will act as a metric for the societal and economic impacts of flood hazards in Turkey. For this purpose, Turkey Disaster Database (TABB) was used for the years 1960-2014. As input for more detailed event analyses, the most severe flood events in Turkey for the same time interval will also be retrieved. Sufficiency of the TABB database to achieve the main aim of the study in terms of data quality and accuracy was also discussed. The TABB database was analysed and reviewed through comparison, mainly with the Emergency Events Database (EM-DAT), the Global Active Archive of Large Flood Events-Dartmouth Flood Observatory database, news archives and the scientific literature, with a focus on listing the most severe flood event. The comparative review of these data sources reveals big mismatches in the flood data, i.e. the reported number of events, number of affected people and economic loss all differ dramatically. Owing to the fact that the TABB is the only disaster loss database for Turkey, it is important to explore the reasons for the mismatches between TABB and the other sources with regard to aspects of accuracy and data quality. Therefore, biases and fallacies in the TABB loss data are also discussed. The comparative TABB database analyses show that large mismatches between global and national databases can occur. Current global and national databases for monitoring losses from national hazards suffer from a number of limitations, which in turn could lead to misinterpretations of the loss data. Since loss data collection is gaining more and more attention, e.g. in the Sendai Framework for Disaster Risk Reduction 2015-2030, this study offers a framework for developing guidelines for the Turkey Disaster Database (TABB), implications on how to standardize national loss databases and implement across the other hazard events in Turkey.

JF - Water / Molecular Diversity Preservation International (MDPI) N2 - The most severe flood events in Turkey were determined for the period 1960-2014 by considering the number of fatalities, the number of affected people, and the total economic losses as indicators. The potential triggering mechanisms (i.e., atmospheric circulations and precipitation amounts) and aggravating pathways (i.e., topographic features, catchment size, land use types, and soil properties) of these 25 events were analyzed. On this basis, a new approach was developed to identify the main influencing factor per event and to provide additional information for determining the dominant flood occurrence pathways for severe floods. The events were then classified through hierarchical cluster analysis. As a result, six different clusters were found and characterized. Cluster 1 comprised flood events that were mainly influenced by drainage characteristics (e.g., catchment size and shape); Cluster 2 comprised events aggravated predominantly by urbanization; steep topography was identified to be the dominant factor for Cluster 3; extreme rainfall was determined as the main triggering factor for Cluster 4; saturated soil conditions were found to be the dominant factor for Cluster 5; and orographic effects of mountain ranges characterized Cluster 6. This study determined pathway patterns of the severe floods in Turkey with regard to their main causal or aggravating mechanisms. Accordingly, geomorphological properties are of major importance in large catchments in eastern and northeastern Anatolia. In addition, in small catchments, the share of urbanized area seems to be an important factor for the extent of flood impacts. This paper presents an outcome that could be used for future urban planning and flood risk prevention studies to understand the flood mechanisms in different regions of Turkey.

T1 - Supra-Pan-African unconformity between core and cover series of the Menderes Massif/Turkey and its geological implications JF - Precambrian research N2 - Well-preserved primary contact relationships between a Late Proterozoic metasedimentary and the metagranitic core and Palaeozoic cover series of the Menderes Massif have been recognized in the eastern part of the Cine submassif on a regional-scale. Metaconglomerates occur as laterally discontinuous channel-fill bodies close the base of the metaquartzarenite directly above the basement. The pebbles in the metaconglomerates consist mainly of different types of tourmaline-rich leucocratic granitoids, tourmalinite and schist in a sandy matrix. Petrographic features, geochemical compositions and zircon radiometric ages (549.6 +/- 3.7-552.3 +/- 3.1 Ma) of the diagnostic clasts of the metaconglomerates (e.g. leucocratic granitoids and tourmalinites) show excellent agreement with their in situ equivalents (549.0 +/- 5.4 Ma) occurring in the Pan-African basement as stocks and veins. The correlation between clasts in the metaconglomerates and granitoids of the basement suggests that the primary contact between the basement and cover series is a regional unconformity (supra-Pan-African Unconformity) representing deep erosion of the Pan-African basement followed by the deposition of the cover series. Hence the usage of 'core-cover' terminology in the Menderes Massif is valid. Consequently, these new data preclude the views that the granitic precursors of the leucocratic orthogneisses are Tertiary intrusions.

T1 - Late Neoproterozoic gabbro emplacement followed by early Cambrian eclogite-facies metamorphism in the Menderes Massif (W. Turkey): Implications on the final assembly of Gondwana JF - Gondwana research : international geoscience journal ; official journal of the International Association for Gondwana Research N2 - Numerous (meta-)gabbroic dikes or stocks occur within the latest Neoproterozoic-early Cambrian series of the Menderes Massif (Anatolide-Tauride Block, western Turkey). These well-preserved rocks were locally converted into eclogitic metagabbros and garnet amphibolites along the contacts or shear zones. Both bulk-rock composition and compositions of igneous clinopyroxenes suggest continental tholeiitic affinity. U-Pb dating of igneous zircons from gabbroic rocks yielded a mean age of 563 +/- 1 Ma (2 sigma), indicating emplacement during the latest Neoproterozoic (Ediacaran). On the other hand, rims of zircons from eclogitic metagabbro gave 535 +/- 3 Ma (2 sigma) (early Cambrian), in addition to 558 +/- 3 Ma (2 sigma) obtained from the igneous core of zircons. These ages are interpreted as the time of high-P metamorphism and crystallization age of gabbroic protolith, respectively. Given the estimated paleogeographic position of the Anatolide-Tauride Block during the late Neoproterozoic and early Cambrian, this orogenic event can be spatially and temporally related to the northward continuity of 600-500 Ma orogenic event (Malagasy/Kuunga orogeny) extending from western margin of India, Madagascar, via Arabia up to northern margin of Gondwana beneath thick Phanerozoic cover series in Arabian Peninsula. Therefore, the high-P evolution of the basement of the Menderes Massif and associated basic intrusions can be interpreted to mark the latest stages of consumption of the basin/oceanic branches and final amalgamation of the Gondwana during the late Neoproterozoic-early Cambrian around the Arabian region.

These processes have created multiple co-genetic fluvial and marine terrace sequences that serve as excellent strain markers to assess the ongoing evolution of the Pontide orogenic wedge and the growth of the northern margin of the Central Anatolian Plateau. We used high-resolution topographic data, OSL ages, and published information on past sea levels to analyse the spatiotemporal evolution of these terraces; we derived a regional uplift model for the northward advancing orogenic wedge that supports the notion of laterally variable uplift rates along the flanks of the Pontides. The best-fit uplift model defines a constant long-term uplift rate of 0.28 +/- 0.07 m/ka for the last 545 ka. This model explains the evolution of the terrace sequence in light of active tectonic processes and superposed cycles of climate-controlled sea-level change. Our new data reveal regional uplift characteristics that are comparable to the inner sectors of the Central Pontides; accordingly, the rate of uplift diminishes with increasing distance from the main strand of the restraining bend of the North Anatolian Fault Zone (NAFZ). This spatial relationship between the regional impact of the restraining bend of the NAFZ and uplift of the Pontide wedge thus suggests a strong link between the activity of the NAFZ, deformation and uplift in the Pontide orogenic wedge, and the sustained lateral growth of the Central Anatolian Plateau flank.

The Afyon Zone contains widespread metavolcanic rocks, which are dominated by rhyolite, dacite, and trachyandesite. They form a distinct volcanic succession, which is separated from the underlying Silurian-Lower Carboniferous metacarbonates and meta-siliciclastics by a regional unconformity. Trachyandesitic metavolcanics are made up of massive lava flows, pyroclastics and epiclastics, less frequently, domes and dikes, which were developed on a deeply eroded subaerial landmass. U/Pb and Pb/Pb zircon geochronology yielded Lower Triassic (similar to 250 Ma) ages, which are interpreted as extrusion age of trachyandesitic volcanics. Based on the stratigraphic, geochronological, and geochemical data, we suggest that these Lower Triassic magmatic rocks represent an extensional tectonic setting on the northern active margin of the Gondwana, which led to the development of the northern branch of the Neo-Tethys.
