Combining field reconstruction and landscape evolution modelling can be useful to investigate the relative role of different drivers (tectonics, climate, local base level) on long term catchment evolution. In this thesis, field reconstruction and landscape evolution modelling are combined to unravel the long-term (300 ka) response to lava damming events of evolution of the Geren Catchment, a tributary of the upper Gediz river near Kula, Western Turkey. This catchment was considered suitable for such a study because its high preservationof remnant landscape surfaces and fluvial terraces which could be dated, while its base level evolution could be reconstructed by identifying and dating lava flows.

In Chapter 2, landscape evolution modelling of an idealized catchment revealed long-term (15 ka) catchment response to natural damming. Evolution of a high erodible and low erodible landscape was simulated using landscape evolution model (LEM) LAPSUS (LandscApe procesS modelling at mUlti dimensions and Scales). The natural dam was given four different erodibilities, to mimic both the potentially more erodible landslide dams and resistant lava dams. In a low erodible landscape damming led to persistent preservation of the sediment wedge formed behind the dam, while in a high erodible landscape, damming additionally led to knickpoint persistence, hampered incision of the main river and stream rerouting. The highest erodible dam was almost removed after 15 ka, while its sediment wedge was still partly present. Comparison of results with natural dam events from literature showed that modelled response characteristics are observed in actual situations and that simulations on Quaternary timescales are useful.

In Chapter 3, field reconstruction resulted in a young lava flow being age constrained to the late Holocene (3.0 – 2.6 ka), by luminescence dating of fluvial sands below and on top of the flow. This lava flow dammed the Gediz river at two locations. the upstream lake was silted, while the downstream lake was not. Dams were breached catastrophically and possibly in a cascading event. The Gediz created an epigenetic gorge and its current river bed is still not at its pre-lava flow level. Results are summarized in a conceptual diagram. Furthermore, field reconstruction and 40Ar/39Ar dating revealed multiple lava dam events which have infrequently raised and lowered the base level of the Geren Catchment in the middle to late Pleistocene (311 – 175 ka). Sediment-capped palaeosurfaces in the Geren suggest change from an active fluvial system to a more lacustrine environment in the middle Pleistocene, followed by fluvial reactivation and stepped incision in the late Pleistocene.

A second landscape evolution modelling study was conducted in Chapter 4, on a 300 ka timescale, with a larger catchment. Four scenarios have been applied on a reconstructed paleodem of the Geren Catchment. In the first scenario, the palaeodem was given constant rainfall for 300 ka. In the second scenario, three short (1 ka) damming events were added at its catchment outlet. In the third scenario, the palaeodem endured gradual base level lowering at its outlet, based on the known incision rate of its base level, the Gediz river. In the fourth scenario, base level lowering and damming events were combined. Results were interpreted by evaluating 1 ka-averaged net erosion, catchment sediment storage, longitudinal profile development and spatial differences in net erosion and sediment storage. Results showed that the net erosion signal of the catchment is complex in all cases. However, average net erosion and its variability increased due to constant base level lowering. Additionally, alternating phases of high and low variability occurred in net erosion, where high variability coincided with a strong decrease in total catchment sediment storage. Adding damming events to the gradual base level lowering scenario generated similar average net erosion as the base level lowering scenario, however its temporal pattern showed significantly different alternation of high and low variability periods. Furthermore, dampened upstream erosion was observed. Over time, this dampening migrates upstream indicating a long-term legacy of short term dam events.

Field reconstruction and landscape evolution modelling were combined in Chapter 5, to be able to reconstruct and understand actual Geren catchment response to identified base level evolution over a 300 ka period. In all simulations, rainfall and vegetation are varied over time based on arboral pollen. Because exact significance and duration of dam events were not known, three scenarios of landscape evolution in the Geren Catchment were investigated: i) uplift driven gradual base level lowering, ii) gradual base level lowering and short damming events and iii) gradual base level lowering and long damming events. Output was evaluated for erosion-aggradation evolution in trunk gullies at two different distances from the catchment outlet. Climate influences erosion – aggradation activity in the upstream reach, although internal feedbacks influence timing and magnitude. Scenario i shows the most correlation with the climate signal, although its correlation is weak. Lava damming events leave an aggradation signal in the downstream reach, while complex and lagged response to these dams obscure correlations with climate and leave a legacy of the past in current landscape evolution. Catchment response of the long dam scenario correspond best with field reconstruction and dating. The combination of climate and base level explains a significant part of the landscape evolution history of the Geren Catchment.

In Chapter 6, a reflection and synthesis of Chapters 2-5 is presented. Indications for response to tectonics, climate and damming events are discussed separately for both field and modelling results. It is concluded that (lava) damming events of Pleistocene age can hamper, but also enhance incision on a 300 ka timescale. Furthermore, they can still have effect on current and future catchment evolution. However, catchment response to this evolution is complex and catchment specific and model results do not exactly reproduce its catchment history. An aggregated landscape evolution model output such as stream bed elevation change can be useful for comparison with fluvial terrace sequences. Combining field reconstruction and modelling suggests that the 300 ka incision history of the Geren is best explained if the catchment endured prolonged dam events. The combination of field reconstruction, dating and landscape evolution modelling therefore can enhance our understanding of long-term evolution of a specific landscape and increases knowledge on long term impact of past events on current catchment complexities and it is suggested to embed this research approach more structurally in long-term landscape reconstructions.

Nationalisms and politics in Turkey: Political Islam, Kemalism and the Kurdish Issue
Casier, M. ; Jongerden, J.P. - \ 2010
London and New York : Routledge (Routledge studies in Middle Eastern politics 26) - ISBN 9780415583459 - 256
nationalisme - etnische groepen - politiek - regering - turkije - islam - sociale situatie - nationalism - ethnic groups - politics - government - turkey - social situation
This book examines some of the most pressing issues facing the Turkish political establishment, in particular the issues of political Islam, and Kurdish and Turkish nationalisms. The authors explore the rationales of the main political actors in Turkey in order to increase our understanding of the ongoing debates over the secularist character of the Turkish Republic and over Turkey’s longstanding Kurdish issue. The book contains contributions on the social and political fabric of Turkey, exploring Turkey’s secularist establishment, the ruling AKP government, the Kurdistan Workers' Party and the Institutions of the European Union. While the focus of concern in this book is with the social agents of contemporary politics in Turkey, the convictions they have and the strategies they employ, historical dimensions are also integrated in their analyses.
Dutch business opportunities in the Turkish biodiesel sector

turkije - bio-energie - biobased economy - biobrandstoffen - turkey - bioenergy - biofuels
To research possibilities for Dutch businesses to be involved in the Turkish biodiesel sector, a short literature study and unstructured interviews with sector stakeholders were performed. Turkey is interested to develop its biofuel sector particularly to improve its security of energy supply, more than climatic based reasons. Turkey is currently importing most of its energy needs. About 50% of oil is used for transportation. Biodiesel has been produced chiefly from imported oilseeds. However, the quantities of locally produced rapeseed and to a lesser extent safflower has increased strongly in the last few years. Biodiesel production grew from 2005 onwards but always remained under its capacity. In mid 2008 production was completely halted. Input prices were high and supporting policies were lacking. Mixing gasoline with biodiesel in Turkey is not mandatory. Economic reforms following the financial crisis in 2001 and a new direct foreign investment law has improved the investment climate for foreign investors. Current possibilities for the Dutch private sector to be involved in the Turkish biodiesel sector are however very limited. Local demand for biodiesel is low and a clear policy focus on biodiesel is still lacking.

The study thus analyses and organises how states oscillate between security logic (‘logic of war’) and non-security logic (‘logic of peace’) in flood security governance. The way floods are managed and politicised are a reflection of how society is organised. Therefore, one should look at flood protection schemes within their social, political, economic context. The study looks at six planned river interventions in five countries, analyses the role of security and risk discourse in conflict and politicisation over river interventions. It finds it is not only state representatives, but also opponents who can effectively ‘speak security’ and play the ‘politics of unease’

Veel Nederlanders hebben misschien een Turkse waterpijp of Marokkaanse theeglaasjes in huis, maar de meeste mensen hebben er geen idee van hoe het er bij Turkse en Marokkaanse Nederlanders thuis uitziet. Dit boek brengt hier verandering in. In twee rijk geïllustreerde en toegankelijk geschreven essays wordt een kleurrijk en levendig beeld gegeven van de interieurs van Turkse en Marokkaanse Nederlanders. Het boekje is geïllustreerd met kleurenfoto’s van de interieurs. De auteurs laten de spanning zien tussen de verschillende Turks-Nederlandse (t)huizen, variërend van oude en soms verouderde negentiendeeeuwse appartementen en vinexwoningen in Nederland, tot lemen plattelandshuizen, vakantiehuisjes en luxueus gemeubileerde villa’s in Turkije. Tussen deze (t)huizen wordt jaarlijks heen en weer gereisd. De auteurs gaan in op de verschillen tussen Turkse en Marokkaanse Nederlanders in hun omgang met traditie en moderniteit. Steeds meer Marokkaanse Nederlanders combineren een westers bankstel met een traditioneel ogende, maar gloednieuwe Marokkaanse salon en gebruiken beide ook daadwerkelijk. Bij de ontvangst van gasten, kiezen Turkse Nederlanders vaker voor de combinatie van een ‘westers’ bankstel en glanzende meubels. Deze worden soms gecombineerd met een museale uitstalling van een reeks ‘authentieke’, oude en niet voor gebruik bestemde Turkse accessoires, eventueel in een ‘oosters’ lounge-hoekje.

This study analyses the agricultural trade relations of the Netherlands with Turkey and with Israel, and investigates the present market positions of the Dutch agribusiness in the two countries. Based on a review of market and agri-food supply chain developments, opportunities for expansion of trade and strengthening of Dutch positions in these two countries are evaluated. The study points at the many export and/or investment opportunities in Turkey for Dutch agribusiness in food products and input supplies and services. At the same time, basic conditions in Israel are not conducive to booming export prospects for Dutch agribusiness companies. The study, conducted at the request of the Ministry of Landbouw Natuur en Voedselkwaliteit, may help the Ministry's desk in Ankara prioritising its activities in Turkey and Israel.
The Settlement Issue in Turkey and the Kurds: an Analysis of Spatial Policies, Modernity and War
Jongerden, J.P. - \ 2007

In seeking to understand village evacuation in the Kurdistan region of Turkey in the 1980s and 1990s, this book focuses on the spatial aspects of the armed conflict. It tries to explain how settlement and resettlement policies and practices in Turkey have been part of a larger project of political and cultural engineering, based on a revision of a classical understanding of modernity as reflected in the work of Durkheim, Mauss, and Tönnies. This interdisciplinary perspective has allowed contributions from sociology to the political sciences and from history to social geography.
