Air pollution can be defined as the increase of pollutants in the atmosphere to the levels that are harmful to humans, other living organisms and the environment which occurs during production and consumption activities. The problem of air pollution is increasing all over the world as a result of various factors such as drought, topographic conditions, inversion and climatic characteristics, as well as reasons such as population growth in cities, increasing urbanization and industrialization. Similar to the world, rising energy demand with population increase, changes in consumption patterns and technological development makes air pollution to be an alarming problem in Turkey. Air pollution is a serious issue that maintains its importance for societies, and it is of great importance to measure air quality, determine the level of air quality, measure its spatial distribution and reveal the pollution sources. Urban mobility, one of the main factors that results in air pollution in cities, was limited by the restrictions applied within the scope of the measures taken to prevent the COVID-19 pandemic all over the world. This situation has created a suitable experimental environment to measure the effect of urban mobility on air quality in cities. In this thesis, the spatial distribution of air pollution caused by urban mobility in Istanbul, which is the most populated city in Turkey, is examined over time. The spatial distributions of major pollutants caused by mobility is modeled with Kriging, a geo-statistical estimation method, and compared for 2019 and 2020, the year curfews took place due to the Covid-19 pandemic. With the decrease in urban mobility, decreases have been observed in the levels of mobility-related pollutants for different time periods of the year. It has been determined that the areas where decreases are observed the most are the ones with heavy vehicle traffic where pollution levels had been the highest prior to curfews.

Urban biodiversity and climate change Puppim De Oliveira, Jose Antonio; Doll, Christopher; Moreno Penaranda, Raquel; Balaban, Osman (Springer, 2014-08-01) Urban biodiversity refers to the variety and variability among living organisms found in a city and the ecological systems in which they occur. Overall, urban biodiversity responds to a combination of biogeographic and anthropogenic factors, with a strong influence of the latter. In a rapidly urbanizing world under the pressing threat of climate change, there is a growing interest in understanding how cities benefit from local biodiversity and how these benefits can be under threat due to climate change. Th...
Comparison of regression and kriging techniques for mapping the average annual precipitation of Turkey Bostan, P.A.; Heuvelink, G.B.M.; Akyürek, Sevda Zuhal (Elsevier BV, 2012-10) Accurate mapping of the spatial distribution of annual precipitation is important for many applications in hydrology, climatology, agronomy, ecology and other environmental sciences. In this study, we compared five different statistical methods to predict spatially the average annual precipitation of Turkey using point observations of annual precipitation at meteorological stations and spatially exhaustive covariate data (i.e. elevation, aspect, surface roughness, distance to coast, land use and eco-region)...
Investigation of Turkey's carbon dioxide problem by numerical modeling Can, Ali; Tokdemir, Turgut; Department of Engineering Sciences (2006) CO2 emission is very important, because it is responsible for about 60% of the "Greenhouse Effect". The major objectives of this study were to prepare a CO2 emission inventory of Turkey based on districts and provinces by using the fuel consumption data with respect to its sources, to find the CO2 uptake rate of forests in Turkey based on provinces and districts, and to estimate the ground level concentration of CO2 across Turkey using U.S. EPA's ISCLT3 model for the preparation of ground level concentratio...
Planning and design criteria to make urban transport more sustainable: the case of Baku Bayramoğlu, Gülnar; Babalık, Ela; Department of City and Regional Planning (2011) Since the industrial revolution, technological developments and increased population have caused environmental damages such as lavish use of sources, pollution increased waste areas, poisoned wastes, harmless gasses, decreased green areas, global warming and climate change, harming of the ozone layer, decreased forests areas and natural sources. Appearance of the term of Global Warming makes the humanity to revise their facilities in all fields. To protect the nature and architectural environment, firstly, ...
Impact Assessment of Urban Regeneration Practices on Microclimate in The Context of Climate Change Akköse, Gizem; Balaban, Osman; Department of Earth System Science (2022-2-10) The annual ever-increase in population, urbanization, industrialization, and CO2 or greenhouse gas emissions brings with it important environmental crises. Climate change and urban heat islands (UHI) are crucial environmental crises that have serious consequences on the performance of the built environment and the comfort and health of users. Moreover, mass migrations from the urban areas and unhabitable cities are envisaged as a result of climate change. To minimize the impacts of climate change and ensure...
