Item Open Access Beyond scarcity: rethinking water, climate change and conflict in the Sudans(Elsevier, 2014) Selby, J.; Hoffmann, ClemensThis article develops a new framework for understanding environment-conflict relations, on both theoretical grounds and through a qualitative historical analysis of the links between water and conflict in the states of Sudan and South Sudan. Theoretically, the article critiques the dominant emphases on ‘scarcity’, ‘state failure’ and ‘under-development’ within discussions of environmental security, and proposes an alternative model of environment-conflict relations centring on resource abundance and globally-embedded processes of state-building and development. Empirically, it examines three claimed (or possible) linkages between water and conflict in the Sudans: over trans-boundary waters of the Nile; over the links between internal resource scarcities and civil conflict; and over the internal conflict impacts of water abundance and development. We find that there exists only limited evidence in support of the first two of these linkages, but plentiful evidence that water abundance, and state-directed processes of economic development and internal colonisation relating to water, have had violent consequences. We conclude that analysts and policymakers should pay more attention to the impacts of resource abundance, militarised state power and global political economic forces in their assessments of the potential conflict impacts of environmental and especially climate change.Item Open Access Climate change and security: different perceptions, different approaches(Uluslararası İlişkiler Konseyi Derneği İktisadi İşletmesi, 2017) Baysal, Başar; Karakaş, UluçThe concerns about the results of climate change have been increasing as new scientific proofs emerge and people witness its direct effects in environmental catastrophes. There also have been different efforts to frame climate change as a security issue. This study aims to analyze different security approaches to climate change with a particular framework. The framework divides these approaches into two: opponents and proponents of the securitization of climate change. It also analyzes different approaches and logics within both camps. Finally, the study examines and evaluates the emerging literature on the “climatization of security” which focuses on the impacts of climate change on the understanding of security in the discipline of International Relations.Item Open Access Collective identity formation and the convergence of brics climate change policy(Bilkent University, 2022-07) Kıprızlı, GöktuğThis dissertation explores what explains the convergence among the BRICS, the acronym standing for Brazil, Russia, India, China, and South Africa, on climate change, despite their divergent characteristics in terms of leading production sectors, demographic trends, population size, emissions profiles, and roles in the energy market. Based on the methodological principles of the theory testing branch of process tracing, there are three potential arguments driven by the existing theories to understand the phenomenon at hand. Hence, the dissertation utilizes soft-balancing of Neorealism, functional cooperation of Liberal Institutionalism, and collective identity formation of Constructivism. The main argument contends that the increasing interaction among the BRICS states, changes in the material world, and, as a result, the cohesion on the basis of collective identity have expanded the web of intra-group cooperation and collaboration within the club and generated shared ideas, discourse, and values on climate change-related issues over time. Adopting an interpretive discourse analysis, the dissertation also relies on primary textual materials consisting of the declarations of the BRICS platform, high-ranking state representatives’ speeches and statements, and other official documents. The dissertation unravels how their collective identity position the BRICS as emerging powers between developed and developing countries and urge their active involvement in tackling climate change in connection with their overlapping discursive, ideational, and policy frameworks. Thus, the dissertation contributes to the literature by unveiling the roots of the convergence among the BRICS, extending the timeframe for uncovering the shared BRICS positions, and marking the relevance of collective identity formation for BRICS cooperation.Item Open Access Economics of climate change and green employment: a general equilibrium investigation for Turkey(Elsevier, 2017) Kolsuz, Güneş; Yeldan, Alp ErinçThis paper quests for the intrinsic complementarities among environmental pollution abatement, induced technological innovation to combat human-induced climate change, targeted expansions for green employment, and enhanced welfare through gains in private income. Utilizing data from the Turkish economy, we implement an applied general equilibrium model to study the synergies between environmental abatement instruments and policies towards sustaining green jobs. Our results are indicative that by a proper mix of environmental taxation and technological and institutional innovations, Turkey can serve as an example for a host of developing countries in setting the stage for a pro-employment and eco-friendly, sustained growth path. We further show that for the successful implementation of a carbon emissions mitigation strategy, elimination of the burden of existing labor taxes and factor market distortions are crucial. Our analysis suggests that complemented with a strategy of substitution of environmental taxes against the existing distortionary labor taxes, costs abatement on domestic income and employment could be negligible.Item Open Access Economics of environmental policy in Turkey: a general equilibrium investigation of the economic evaluation of sectoral emission reduction policies for climate change(Elsevier Inc., 2008) Telli, Ç.; Voyvoda, E.; Yeldan, E.Research on climate change has intensified on a global scale as evidence on the costs of global warming continues to accumulate. Confronted with such evidence, the European Union set in late 2006 an ambitious target to reduce its greenhouse gas emissions, by 2020, to 20% below the level of 1990; and invited the rest of the developed economies and the developing world to take part with the Kyoto Protocol. Turkey is the only country that appears in the Annex-I list of the United Nations' Rio Summit and yet an official target for CO2 emission reductions has still not been established. Thus, as part of its accession negotiations with the EU, Turkey will likely to face significant pressures to introduce its national plan on climate change along with specific emission targets and the associated abatement policies. Given this motivation, we utilize a computable general equilibrium model for Turkey to study the economic impacts of the intended policy scenarios of compliance with the Kyoto Protocol and we report on the general equilibrium effects of various possible environmental abatement policies in Turkey over the period 2006-2020. The model is in the Walrasian tradition with 10 production sectors and a government operating within an open macroeconomy environment. It accommodates flexible production functions, imperfect substitution in trade and open unemployment. We focus on CO2 emissions and distinguish various basic sources of gaseous pollution in the model. Our results suggest that the burden of imposing emission control targets and the implied abatement costs could be quite high, and that there is a need to finance the expanded abatement investments from scarce domestic resources. Policies for environmental abatement via carbon and/or increased energy taxes further suffer from very adverse employment effects. This suggests that a first-best policy would necessarily call for a simultaneous reduction on the existing tax burden on producers elsewhere together with introduction of environmental taxes. © 2007 Society for Policy Modeling.Item Open Access Energy and environmental policy against climate change in Turkey(Academic Press, 2018) Acar, S.; Voyvoda, E.; Yeldan, Alp ErinçBased on the structure of the economy in general but especially focusing on the duality patterns laid out in Chapter 2, this chapter first examines the recent energy and environment statistics in Turkey, and second, evaluates the existing (energy and environmental) policy framework and future potential of these policies in terms of their implications for climate change. We argue that the lack of mitigation at the aggregate national level finds its manifestation in the widening gap across regional GHG emissions as a consequence of the dual economic structure and the lack of differential policies across the regions.Item Open Access Environmental impacts of coal subsidies in Turkey: a general equilibrium analysis(Elsevier, 2016) Acar, S.; Yeldan, Alp ErinçIn this study we aim at providing an analytical framework for Turkey to study the macroeconomics and environmental impacts of the existing coal subsidization scheme. To this end we develop a regionally differentiated applied general equilibrium model spanning over 2015-2030. Our analytical apparatus focuses exclusively on the fiscal implications as well as the environmental repercussions of the removal of the subsidies on greenhouse gas emissions. With the aid of a set of alternative policy scenarios against a "business as usual" path, we study the regional and sectorial performances of growth, employment, investment and capital accumulation, consumption/welfare and trade balance. Our results indicate that by simple elimination of the coal subsidization scheme, Turkey can reduce its aggregate gaseous emissions by as much as 5% without a significant loss in its GDP.Item Embargo Establishing initial urban bioclimatic planning recommendations for Ankara to address existing and future urban thermophysiological risk factors(Elsevier, 2023-05) Nouri, A. Santos; Rodriguez-Algecíras, J.; Matzarakis, A.Focused on the case of Ankara, human thermophysiological thresholds were investigated in association with typical morphological characteristics to determine the frequency of seasonal Heat/Cold Stress. The study further developed methodical means to better understand the relationship with local radiation exposure within in-situ settings, allowing for the better understanding of seasonal thermophysiological exposure upon human biometeorology. To approach future vulnerability and frequency of thermophysiological stress, daily EURO-CORDEX data was processed to determine Representative Concentration Pathway scenario projections (for air temperature and Physiologically Equivalent Temperature (PET)). The study highlighted the already significant urban frequencies of heat stress (ranging up to 82.7%) due to all districts witnessing an elevated frequency of low aspect ratios. The fewer mid-range aspect ratios also revealed to be frequently in orientations with higher heat stress susceptibilities (i.e., between 105° and 150°). Bioclimatic planning recommendations were presented for Ankara. Nevertheless, given the high vulnerability for existing/future urban human health and welfare, these recommendations were further associated with the call for immediate heat action plans and heat warning/mapping systems. In these first type of projections for Ankara, even for the milder/stabilization future scenario by 2100, PET based projections revealed frequencies remaining at 100% between 35.1 °C–41.1 °C, with further values exceeding 46.1 °C.Item Open Access Human thermo-physiological comfort assessment in Lisbon by local climate zones on very hot summer days(Frontiers Research Foundation, 2023-05-17) Reis, C.; Nouri, Andre Santos; Lopes, A.Extreme heat is a current and future issue on urban areas, with negative impacts on health and quality of life (increasing morbidity and mortality rates). This paper analyses day (12:00–15:00 h) and nighttime (00:00–03:00 h) thermo-physiological comfort (TC) conditions by Local Climate Zones (LCZ) in Lisbon during a particular Local Weather Type (LWT), very hot summer days. For this, 13 different microscale sample areas were chosen covering urban and non-urban land cover classes (LCZs 1–3, 4–6, 8, 9, A and B). Universal Thermal Climate Index (UTCI) and Mean Radiant Temperature (MRT) were modeled on SkyHelios software for 163 days between 2008 and 2014. Results show that during the day all urban LCZ samples depict the same average TC conditions (average UTCI of 34°C—strong heat stress) and densely wooded areas are 2°C cooler (average UTCI of 32°C—moderate heat stress). However, compact areas (LCZs 1–3) with low sky view factor and some vegetation (street trees) display lower percentages of area with higher thermo-physiological discomfort (TD) levels (83% with strong heat stress against 98% in LCZs 8 and 9 and 100% in LCZs 4–6). When considering the hottest days (air temperatures equal or above 35°C—75th percentile), the moderate heat stress class disappears in all samples and the very strong heat stress class appears only on urban areas, occupying between 12% and 16% on LCZs 1–3, 10%–22% on LCZs 4–6, 16%–22% on LCZs 8 and 9 on LCZ 9. During the nighttime period all samples show no thermal stress, favoring nocturnal physiological recovery. TC conditions in Lisbon are strongly influenced by solar radiation and wind, which explains the need to increase the shading area, preferably by trees, and to promote and preserve ventilation paths.Item Open Access In the presence of climate change, the use of fertilizers and the effect of income on agricultural emissions(M D P I AG, 2017) Erbas, B. C.; Solakoglu, E. G.This study looks into the factual link between nitrogen fertilizer use and the land annual mean temperature anomalies arising from climate change, incorporating the effect of income and agriculture share to understand better their impact on emissions from agricultural activities along climate indicators. The study unearths causalities associated with this link by employing the Vector Error Correction Model (VECM) with back-dated actual panel data specifically constructed for this study by combining four datasets from 2002 to 2010. In the long-run, the causality is significant and unidirectional, indicating that income, agriculture share, and land temperature anomalies cause agricultural emissions, and that disequilibrium from such emissions is not eliminated within a year. In the short-run, the effective use of nitrogen fertilizers and other associated agricultural practices can be achieved as countries approach per capita income of 7000 USD. Changes in the structure of economies have an expected effect on agricultural emissions. Temperature anomalies increase agricultural emissions from nitrogen fertilizers, possibly due to the fact that the potential negative impacts of these anomalies are mitigated by farmers through changes in crop production inputs. Therefore, as part of adoption strategies, to avoid the excessive and inefficient use of nitrogen fertilizers by farmers, economic incentives should be aligned with the national and global incentives of sustainability. © 2017 by the authors.Item Open Access Patterns of growth in dual economies: challenges of development in the 21st century(Academic Press, 2018) Acar, S.; Voyvoda, E.; Yeldan, Alp ErinçThis chapter attempts to examine patterns of growth in dual economies within the context of challenges of development for the 21st century. To this end, we first study the broad contours of growth and adjustments in the global economy, before, during, and after the 2008–09 global crisis. Here four general patterns emerge, namely, stagnation of wage incomes; declining investment effort; consequent decline in the rates of growth of productivity; and a compensatory rise in corporate and household indebtedness. The chapter continues with a deeper investigation of the structural sources of deindustrialization and widening duality in both labor markets and technological diffusion. Finally, we link all these ideas with the macroeconomics of global climate change and implications on the feedback effects of the economy-resource use-environmental degradation nexus.Item Open Access Rethinking climate change, conflict and security(Taylor&Francis, 2014) Selby, J.; Hoffmann, ClemensThis special issue of Geopolitics presents a series of critical interventions on the links between global anthropogenic climate change, conflict and security. In this introduction, we situate the special issue by providing an assessment of the state of debate on climate security, and then by summarising the eight articles that follow. We observe, to start with, that contemporary climate security discourse is dominated by a problematic ensemble of policy-led framings and assumptions. And we submit that the contributions to this issue help rethink this dominant discourse in two distinct ways, offering both a series of powerful critiques, plus new interpretations of climate-conflict linkages which extend beyond Malthusian orthodoxy.Item Open Access The onset of BRICS cooperation on climate change: material change, ideational convergence and the road to Copenhagen 2009(Routledge, 2023-02-20) Kıprızlı, G.; Köstem, SeçkinWhat explains the convergence among Brazil, Russia, India, China and South Africa (BRICS) on climate change? While Brazil, India, China and South Africa caught attention due to their economic dynamism in the 1990s and accelerating momentum as of the early 2000s, Russia progressed to increase its influence in the twenty-first century. This shift in the material capabilities of BRICS has increased their significance in global climate governance. Merging governmentality and social constructivist approaches, this article argues that material changes in the post-Cold War period led Brazil, India, China and South Africa to experience a change in their ideational framework, repositioning themselves at the international level, recognising new responsibilities, and reaching a common point on the road to the Copenhagen Climate Change Conference in 2009. Therefore, they went through a convergence process, bringing them closer to Russia, whose position invited major developing states to take tangible actions for emissions reduction. This process of convergence marked the onset of the future BRICS partnership on climate change.Item Open Access Time-varying cointegration and the Kalman filter(Taylor and Francis, 2022) Eroğlu, B. A.; Miller, J. I.; Yiğit, TanerWe show that time-varying parameter state-space models estimated using the Kalman filter are particularly vulnerable to the problem of spurious regression, because the integrated error is transferred to the estimated state equation. We offer a simple yet effective methodology to reliably recover the instability in cointegrating vectors. In the process, the proposed methodology successfully distinguishes between the cases of no cointegration, fixed cointegration, and time-varying cointegration. We apply these proposed tests to elucidate the relationship between concentrations of greenhouse gases and global temperatures, an important relationship to both climate scientists and economists.Item Open Access Understanding the BRICS framing of climate change: The role of collective identity formation(SAGE, 2022) Kıprızlı, Göktuğ; Kostem, SeçkinThis article explores how the BRICS states (Brazil, Russia, India, China, and South Africa) frame the issue of climate change. Based on constructivist insights, the article argues that the formation of collective identity has fundamentally shaped the BRICS framing of climate change. On the one hand, BRICS0 connections to the developing world explain why BRICS has given voice to the arguments of developing countries with respect to climate change. On the other hand, BRICS0 policy concepts, ideas, and discourse reflect the attributes associated with the identity of emerging powers. This article argues that emerging power status encourages the BRICS states to portray themselves as responsible actors on the global scale and conceptualize a climatesensitive economic development model in contrast to the Western production paradigm that is regarded as unsympathetic towards the needs of developing nations. In this process, the perception of the developed world as the relational other supports the sense of we-ness among the BRICS states, thereby shaping their policy formulations with respect to climate change.
