Article Promoting Utilization of Biofuels in the Transportation Sector To Reduce Co2 Emissions: Comparative Analysis(Gazi Univ, 2022-12-16) Bozbay, Utku; Güngörmüşler, MineIn this study, due to the high contribution of the transportation sector to generate CO2 emissions, an evaluation for the best scenario of the replacement of petroleum derived fuels by renewable and sustainable alternatives was assessed with a multi collative approach suggesting the second-generation bioethanol as the most promising one. In this context, this paper focused on the practices over the past 23 years in the following four countries; Turkey, China, Sweden, and Brazil, with a comparative regression analysis between the CO2 emissions generated from the consumptions of total energy and biofuels. Accordingly, a curve-fitting and an estimation on the formation of CO2 emissions with the incrementing blends of gasoline by 3 to 100% of bioethanol was forecasted for 2020 to 2030. The outcomes of the comprehensive research indicated the international and national benefits of biofuel use, thus, promoting the potential integration of bioethanol in the Turkish transportation sector.Article Citation - WoS: 2Between the State and the World Market: Small-Scale Hazelnut Production in the Black Sea Region(Istanbul Univ, Fac Letters, Dept Sociology, 2020-07-27) Erköse, Hüseyin Yener; Sahin, Osman; Yukseker, Deniz; Sert, Deniz H.; Sert, Huseyin DenizTurkey is the world's largest hazelnut producer and exporter, yet hazelnut farmers have been growing hazelnuts in increasingly difficult conditions even for the years when production levels and hazelnut prices are high. In this paper, we take up the contradictions in hazelnut cultivation in Turkey and seek to show that, despite the commonsense opinion that the problem stems from small-scale cultivation, the more important problem is the unequal power relations that exist in the hazelnut market. We make the following arguments in the paper based on some of the findings from the field study we carried out in the Western and Eastern Black Sea regions in 2017. Issues exist regarding productivity and profitability in hazelnut cultivation characterized by small holdings. Hazelnut farmers are often unable to meet the expenditures and investments required for raising productivity. These problems arise more from the farmers' demographic profiles and debt levels and the unequal power relations in the hazelnut market with respect to small-scale production. Therefore, resolving the problems in hazelnut cultivation might require making changes that favor small farmers' power relations in the hazelnut market rather than enlarging holdings.
