An Assessment of Mining Efficiency in Turkish Lignite Industry
(Elsevier Science, 2015) Ediger, Volkan S.; Berk, Istemi; Ersoy, Mucella
This article focuses on the mining activities of Turkish Coal Enterprises (TKI) the major lignite supplier in Turkey. First we analyzed the lignite production and overburden removal activities of TKI from a historical perspective and then employed the Principle Component Analysis to build a mining efficiency index of TKI and investigated its historical development since the establishment of the company. We found that labor productivity and operational structure have been the most important factors positively affecting the index. The current article makes two important contributions: (1) by using the most comprehensive data set available on TKI for the first time and (2) by developing a Mining Efficiency Index (MEI) which can be used to analyze productivity in lignite mining activities in different countries.

A Crude Marriage: Iraq Turkey and the Kirkuk-Ceyhan Oil Pipeline
(Routledge Journals Taylor & Francis Ltd, 2017) Bowlus, John V.
Since the discovery of oil at Kirkuk in northern Iraq oil has shaped relations between Iraq and Turkey as the former needed markets and export routes to the Mediterranean and the latter reliable sources of supply. This article examines the origins of the Kirkuk-Ceyhan oil pipeline from northern Iraq to the Turkish Mediterranean coast charting the period of Iraqi-Turkish economic rapprochement in the 1960s to the construction of the pipeline in the 1970s. It also seeks to add to our collective understanding of why transnational oil pipelines in the Middle East succeed or fail by examining the pipeline's operational record.

The Effect of Energy Geopolitics on International Climate Change Initiatives
(Uluslararası İlişkiler Konseyi Derneği, 2017) Ediger, Volkan S.
In this article in general the relationship between international climate change initiatives and energy geopolitics was analyzed and in particular the developments in energy geopolitics were investigated with a historical point of view by dividing the years between 1965 and 2014 into periods of geopolitical intensity and geopolitical stability based on long-term periodic variations in oil prices. More specifically the reasons why international initiatives such as the Kyoto Protocol regarded as an important agreement for imposing commitments in climate change mitigation have not been sufficiently successful were investigated. Regarding the Kyoto Protocol the failure stemmed from three main reasons. The first and the most important reason was the intensification of geopolitical tensions on a global scale. The second reason was the differences among states in terms of their energy needs and possession of indigenous energy sources. The last reason was the ambiguity regarding the role of the state and the market at the implementation level. The author links the general failure in the efforts to tackle climate change to the developments in energy geopolitics and argues that the competition periods in energy geopolitics as observed during the oil crises decrease the chances of success for international initiatives on climate change.
Enerji Jeopolitiğinin Uluslararası İklim Değişikliği Girişimleri Üzerindeki Etkisi
(Uluslararası İlişkiler Konseyi Derneği İktisadi İşletmesi, 2017) Ediger, Volkan S.
Genel olarak iklim değişikliği girişimleri ile enerji jeopolitiği arasındaki ilişkinin analiz edildiği bu makalede, başta petrol fiyatlarındaki artışlar olmak üzere, enerji jeopolitiğindeki gelişmeler, 1965-2014 arasında enerji jeopolitiğinin şiddetlendiği ve durağanlaştığı dönemlere ayrılarak, tarihsel bakış açısıyla incelenmiştir. Özel olarak, Kyoto Protokolü gibi iklim değişikliğinin önlenmesi konusunda yükümlülük getirmesi bakımından önemli bir anlaşma olarak kabul edilen uluslararası girişimlerin neden yeterince başarılı olmadığı araştırılmıştır. Kyoto Protokolü özelinde başarısızlığın üç temel nedeni bulunmaktadır. Bunlardan birincisi ve en önemlisi dünya genelinde enerji jeopolitiğinin şiddetleniyor olmasıdır. İkinci neden ülkelerin farklı enerji ihtiyaçları ve farklı yerli enerji kaynaklarının bulunması, üçüncüsü de uygulamalarda devlet ve özel sektörün rolünün yeterince belirgin olmamasıdır. Yazar, iklim değişikliği konusundaki genel başarısızlığın başlıca nedenini enerji jeopolitiğindeki gelişmelere bağlamakta ve petrol krizleriyle somutlaşan küresel enerji politiğindeki mücadele dönemlerinin, iklim değişikliği gibi konulardaki uluslararası girişimlerin başarı şansını azalttığını savunmaktadır.

Europeanization Under Membership Uncertainty: the Cases of Environmental and Energy Policy in Turkey
(Uluslararası İlişkiler Konseyi Derneği, 2013) Yıldırım, Cagri; Baysan, Alper; Ediger, Volkan S.
This article examines modalities of rule adoption from the EU's acquis communautaire under conditions of membership uncertainty Drawing upon the case of Turkey we probe into the viability of a policy-type approach (drawing upon Theodor Lowi). Our main contention is that the substantive design of policies (distributive or redistributive qualities) has consequential implications for the form (conflict-free vs. veto player constellations) and outcome (transposition likelihood) of the subsequent political process. The proposed policy-type approach internalist in its outlook is thus readily compatible with available Europeanization models which are externalist insofar as being premised on the study of domestic politics. In terms of policymaking the EU needs to make more frequent use of policy-based intermediate rewards to encourage rule adoption where membership prospects are uncertain.

Forecasting the Coal Production: Hubbert Curve Application on Turkey's Lignite Fields
(Elsevier Science, 2016) Berk, Istemi; Ediger, Volkan S.
The dependence on imported energy sources is one of the biggest challenges that Turkey and many other similar countries face in the 21st Century and the gap between production and consumption cannot be decreased without increasing the domestic production. Forecasting of domestic energy production therefore plays a vital role in order to be able to develop sound energy policies towards maintaining sustainable development. However although this question is essential in this respect especially for import dependent countries the previous literature is surprisingly scarce. This paper therefore will be important for future studies on estimation of energy production. We first analyzed lignite production of Turkish Coal Enterprises (TKI) from a historical perspective and then forecasted the future production by using the Hubbert curve depletion rate and decline curve methodologies. We concluded that the largest fields are about to enter a declining phase of production in upcoming years and most of the reserves will remain untapped if business-as-usual continues in the future. The methodology and interpretations may be used by other developing countries which deeply suffer from energy import dependency.

The great game in the Levant: energy geopolitics in the Eastern Mediterranean [Levant’ta büyük oyun: Doğu Akdeniz’in enerji jeopolitiği]
(Uluslararası İlişkiler Konseyi Derneği, 2012) Ediger, Volkan S.; Devlen, Balkan; McDonald, Deniz Bingöl
This study explores the historical evolution of the Levant region from the trade system to hydrocarbon geopolitics by using a longue duree approach one which evaluates the region's present situation in light of developments in oil and natural gas exploration production and export. The concepts of great power politics and balance of power frame the investigation of permanent and changing dimensions of hydrocarbon geopolitics. The first of the two hypotheses tested and verified in this study is that the geopolitics of the Levant maintains its historical importance for the global hegemon and for the international state system even though the central thrust of the Levant's geopolitics has been tranformed from trade to energy. The second hypothesis is that regional and global peace and stability increase when the geopolitics of the Levant is in the control of a hegemon. Instances of conflict increase and opportunities for cooperation decrease when the Levant's geopolitics slips from the grasp of a single hegemon as a result of shifts in the balance of power. Following a discussion of threats and opportunities for conflict and cooperation in the Levant region possible strategies for the regional actors are evaluated. Lastly the threats and opportunities that Turkey faces are situated within emergent trends in the energy geopolitics of the region.

An Integrated Review and Analysis of Multi-Energy Transition From Fossil Fuels To Renewables
(Elsevier Science Bv, 2019) Ediger, Volkan S.
We are in the midst of a transition from a fossil fuel-dominated energy regime to a more sustainable lower-carbon one in which natural gas is a bridge fuel. Since the 1970s oil crises, however, the forecasts for gas and coal have changed three times. Gas is currently achieving a major position in the world's energy mix but under challenging geopolitical forces; for this reason, different countries will follow different paths for adopting gas. This article uses a ternary diagram to shows that the fossil fuel consumption paths of the powers have greatly diverged over time. The close relationship between world hegemony and the dominant energy source (coal and then oil) in the past will be replaced by a multi-energy transition in which different countries choose different energy regimes in a multipolar international system.

Levant’ta Büyük Oyun: Doğu Akdeniz’in Enerji Jeopolitiği
(Uluslararası İlişkiler Konseyi Derneği İktisadi İşletmesi, 2012) Ediger, Volkan S.
Levant Bölgesi’ndeki ticaret sisteminden başlayarak bölgenin hidrokarbon jeopolitiğine geçiş sürecine kadar uzanan tarihsel gelişimin uzun erimli (longue dureé) bakış açısıyla incelendiği bu çalışmada, bölgenin günümüzdeki durumu, petrol ve doğal gazın arama, üretim ve ihracı konusunda özellikle 2000’li yıllardan bu yana yaşanan gelişmelerle değerlendirilmiştir. Bölgenin hidrokarbon jeopolitiğindeki çatışma ve iş birliğinin sabit ve değişen boyutlarına, uluslararası ilişkilerin güç politikaları ve güçler dengesi gibi kavramları çerçevesinde özel bir yer verilmiştir. Bu çalışma sonunda test edilerek doğrulanan iki temel hipotezden bir tanesi, zaman içinde ticaretten enerjiye evrimleşen Levant jeopolitiğinin, küresel başat güç ve uluslararası devletler sistemindeki güç dengeleri için önemini uzun tarihi boyunca koruduğudur. Buna bağlı olarak geliştirilen ikinci hipotez de, Levant jeopolitiğinin kontrolünün başat gücün elinde olduğu zamanlarda bölgesel ve küresel çaptaki barış ve istikrarın arttığıdır. Güç dengelerindeki kaymalardan ötürü Levant’taki jeopolitik kontrol tek bir gücün elinden çıkmaya başladığı zamanlarda çatışmalar artmakta, iş birlikleri azalmaktadır. Doğu Akdeniz’in enerji konusunda günümüzde karşı karşıya kaldığı tehdit ve fırsatların incelenmesinin ardından bölgedeki çatışma ve iş birliği olanakları konusunda çıkarımlar yapılarak, bölgesel aktörlerin temel stratejileri değerlendirilmiştir. Levant’ta öne çıkan yeni enerji jeopolitiğinin bölgenin önemli bir gücü olan Türkiye için oluşturacağı tehdit ve fırsatlar tartışılmıştır.

The Only Thing We Have To Fear: Post 9/11 Institutionalization Of In-security [korkmamız Gereken Tek Şey: 11 Eylül Sonrasında Güvensizliğin Kurumsallaşması]
(Uluslararası İlişkiler Konseyi Derneği, 2012) Çelikpala, Mitat; Öztürk, Duygu
During the last decade billions of dollars have been spent to increase security measures in the United States. New institutions including a department for homeland security have been established new security tools have been developed and surveillance of Americans has been increased. However despite the creation of 'safety zones' neither the level of the Americans' feeling of security from further terrorist attacks nor their confidence in the ability of US governments to prevent attacks has seen an increase. According to Beck who introduced the concepts of 'world risk society' and 'reflexive modernity' terrorism is one of the products of reflexive modernity which cannot be addressed by traditional security measures. Within this framework this paper analyzes the case of the Americans since 9/11 attacks. In this vein it is argued that the gap which has arisen as a result of addressing non-territory and non-state-based terrorism through state-based security measures has caused a continuation of a high level of insecurity fear and anxiety among the Americans. Public opinion surveys conducted in the United States since the 9/11 attacks by various institutions are used to analyze Americans' thoughts about security and the terror risk in the United States.
