TY - JOUR A1 - Koc, Gamze A1 - Petrow, Theresia A1 - Thieken, Annegret T1 - Analysis of the most severe flood events in Turkey (1960-2014) BT - which triggering mechanisms and aggravating pathways can be identified? 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.

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.
