This study investigates the tradeoffs between water and food (agriculture) nexus and evaluates alternative scenarios focusing on sustainable water governance for agricultural production in Upper Sakarya Basin. For this purpose, pressures on surface water and groundwater resources are determined for the study period (2004-2016) by considering inputs and outputs such as demand, supply, and discharge by all sectors. With concentrating on the impacts on demand and supply dynamics, the effectiveness of management scenarios in the agricultural sector is evaluated using the WEAP model. Demand-oriented management scenarios propose various technical measures that include improvements in irrigation technology, shifts in the cropping pattern, and conservative irrigation strategies. Scenario analysis has shown that demand and supply decline in proportion to each other, resulting surface water reliability to rise at a relatively lower rate. It is suggested that water and food (agriculture) sustainability is facilitated when less water-intensive crops are favored and efficient irrigation techniques and deficit irrigation programs are adopted.

Models of regulating water in transboundary river basins: a nexus of hydropolitics and electricity trade
Sakal, Halil Burak; Tanrısever, Oktay Fırat; Department of International Relations (2018)
The central topic of this study is the nexus between water and hydroelectricity. The main issue discussed here is how economic activity influences and is being influenced by water management, hydroelectricity production and electricity trade in key trans-boundary river basins. The unit of analysis is the state, the limits of which are defined by modern political boundaries; and the geographically demarcated river basins that involve the selected cases are subject to evaluation in broader context. In terms o...
An Assessment of the Spatial Distribution of Polychlorinated Biphenyl Contamination in Turkey
Gedik, Kadir; İmamoğlu, İpek (Wiley, 2010-02-01)
This study summarizes the relevant information regarding the spatial distribution of polychlorinated biphenyls (PCBs) in various environmental (e.g., soil, sediment, air, water) and biological (e.g., fish, mussel, adipose tissue, milk) media in Turkey. The information sources, used for this purpose, in addition to the scientific literature, were; official import records, governmental reports on monitoring of organochlorines, and reports prepared by international organizations. PCBs were never produced in Tu...
Degradation of decabromodiphenyl ether (BDE-209) in microcosms mimicking sediment environment subjected to comparative bioremediation strategies
Demirtepe, Hale; İmamoğlu, İpek (Elsevier BV, 2019-03-01)
The aim of this study was to examine bioremediation strategies for BDE-209 contaminated sediments. Sediment microcosms were established to observe anaerobic debromination of BDE-209 under conditions representing three bioremediadon strategies: biostimulation, bioaugmentation and natural attenuation. To simulate biostimulation, a defined mineral medium containing both a carbon source (sodium formate) and electron donor (ethanol) was added into sediments. Bioaugmentation was established by enrichment of the s...
Synthesis and characterisation of PANI- coated Heliotrope Leaves (PANI@HL) with high clean-up capacity for Orange G dye from aqueous media

The main objective of this study is to optimise a new composite for the depollution of contaminated water. This pollution can have adverse effects on both human health and the environment. The aim of this work was the elaboration and characterisation of a Novel polyaniline composite with plant leaf powder of Heliotrope (PANI@HL) for the removal of Orange G dye in an aqueous media. Hence, the physicochemical and morphological composition of PANI@HL were characterised by field-emission-scanning-electron-micro...
Modification of a Conventional Anaerobic Digester for Improving the Effluent and Sludge Characteristics
Uludag-Demirer, S.; Demirer, Göksel Niyazi; Othman, M. (Wiley, 2009-12-01)
The aim of this study was to enrich the composition of anaerobic digester sludge in terms of nitrogen and phosphorus by struvite (MgNH4PO4) formation. Waste activated sludge was anaerobically digested in batch reactors under the conditions that the minimum stoichiometric requirement for struvite formation was satisfied in all reactors. For this purpose, different amounts of magnesium (Mg2+) and phosphate (PO43-) ions were added initially to the batch reactors. The results showed the effects of adding Mg2+ a...
