As the public and policy makers continue to become more concerned with climate change, researchers continue to seek to understand and explain energy and greenhouse gas (GHG) emissions trends and their drivers. Living and existing in different areas is associated with different impacts, so growth in different areas, as well as the movement of people to and from those areas will affect energy use and emissions over US, individual states, and counties. First the emissions implications of state to state mobility on household energy and GHG emissions are explored. 3 million households move across state lines annually, and generally move from the North East to the South and West. Migrating households often move to states with different climates, and thus heating and cooling and needs, different fuel mixes, and different regional electricity grids which leads them to experience changes in household emissions as a result of their move. Under current migration trends, the emissions increases of households moving from the Northeast to the South and Southwest are balanced by the emissions decreases of households moving to California and the Pacific Northwest. The net sum of emissions changes for migrating households is slightly positive but near zero; however, that net zero sum represents the balance of many emission changes. Summing emissions changes over individual states and regions show the regional differences in household emissions. Next, a similar analysis is conducted for the 120,000 households that annually move between counties in Pennsylvania. From 2006–2010, the emissions changes experienced by those households balanced to near zero values, similar to the state analysis. The emissions increases from households moving to metropolitan fringe and suburban counties were countered by the emissions decreases from households moving to low emission urban centers, even though urban centers experienced net negative migration. While emission changes experienced by households were dominated by differences in emissions from residential energy use, emission changes for household moving within Pennsylvania were dominated by differences from transportation emissions. Finally, this thesis explores the long term effects of growth and decline at the metropolitan level by estimating fossil based CO2 emissions from1900−2000 for Allegheny County, Pennsylvania. From 1970 to 2000, Allegheny County experienced a 30% decrease in total emissions and energy use from peak values, primarily because of a decline in industrial activity! (40% decrease in value added) and the loss of a quarter of its population. Allegheny County’s history suggests that the scale of change needed to achieve local emissions reductions may be significant; given years of major technological, economic, and demographic changes, per capita emissions in 1940 were nearly the same in 2000. Most local governments are planning emissions reductions rates that exceed 1% per year, which deviate significantly from historical trends. These results suggest additional resources and improved planning paradigms are likely necessary to achieve significant emissions reductions, especially for areas where emissions are still increasing. This work shows that overtime, growth and decline within a! region drives its evolving GHG footprint. Population decline within region may lead to emission reductions, as seen in the Allegheny County, but those reductions are more accurately described as displaced emissions due to population redistribution. From 2005-2010, the mobility of the US population between states, regions and counties was responsible for many household emissions changes that balance annually over the entire US. The near zero sum represents the v precarious emissions balance of two kinds of household moves. First, moves resulting in moderate emissions increases either as a result of households moving to higher carbon regions, like the South or South West, or as a result of households moving higher carbon suburban counties within states. Second, moves resulting in significant emissions decreases! As a result of households moving to low carbon regions or low carbon urban centers. Planning for continued low carbon growth in low carbon regions or cities experiencing high growth rates driven by migration, like California or Philadelphia, is essential in order to offset the moderate emissions increases experienced by households moving to high carbon regions or suburban areas.

This thesis investigates the underestimated ownership constraints in built-up urban areas as the determining characteristic of the urban redevelopment process after the Marmara Earthquake. In the first part of the study, public provisions for permanent housing have been surveyed. It is observed that relocation of the survivors entitled to such housing sites considerably far away from existing urban areas has generated the need for many adjustments on the property patterns. Without any framework for the remaining ownership and development rights in those damaged urban areas, nearly 43 000 housing units have been developed mostly by the state in order to compensate for the lost properties of disaster survivors. On the other hand, municipalities could not commence any considerable redevelopment framework in damaged urban areas after the earthquake. They were restricted to revising their development plans with respect to new geological surveys and to redefining the ideal building regulations with low building heights. Adaptation of these renewed plans to existing conditions has necessitated an immense amount of property readjustments. However, this is nearly impossible with existing plan implementation instruments which are incapable of mandating the exchange mechanisms for the reduced development rights. Lack of three dimensional property adjustment and purchasing methods different from constructions option engendered the implementation problem of these development plans prepared after the earthquake. In this framework, a field survey has been carried out in the city of Adapazari and the post-earthquake urban redevelopment process is investigated. Transformation of the properties are plotted in &Ccedil / ark Street, where the required resharing of reduced development rights with respect to new development plan can be partially observed. Besides, the success of the forthcoming urban planning process in Turkey, which is composed of urban rehabilitation and risk mitigation works, again depends upon the capacity to realize ownership and development right transformation in urban environments. As a result, the Marmara Earthquake presents the necessary inputs and justification to restructure the property institution in urban planning.

As a result of the disregard of governments&rsquo / direct urbanization policies for more than 50 years, most of the settlements in Turkey today demonstrate sub-standard environments and unauthorized developments subject to severe natural hazards. Turkey will have to focus in the near future on the renewal and regeneration of cities built over the past six decades, rather then sticking to urban policies solely devoted to extend new urban areas. The production of legal instruments and urban policies to facilitate the new policy of regeneration in physical and social terms, seems to be the most challenging issue facing urban planning. Urban regeneration planning aims to produce strategies and policies concurrently devoted to maintain physical rehabilitation and social transformation in built areas. For this reason, urban regeneration planning requires legal tools, regulations and methods different then those of conventional development planning. A new approach to urban regeneration planning is the development of urban database systems. These sytems are discussed here by means of a model developed for the case of Zeytinburnu. This model is prepared by organizing and developing the urban databases produced by local governments and international institutions for istanbul integrating natural conditions, physical assets, and the social characteristics. This requires a new set of &lsquo / Analytical Studies&rsquo / approach. The main obstacle in urban database system in Turkey is the lack of legal arrangements. New regulations are needed to describe the organisation and principles of database management in technical and administrative terms. Other implications are that an entirely new generation of urban planners need to be trained, improvement of expertise on database management, database use and updating protocols. Such systems could also constitute an essential instrument of public participation in local planning and urban management process.

This dissertation investigates three economic aspects of the climate change issue: optimal allocation of investment between adaptation and mitigation, impacts on a ground water dependent regional agricultural economy and effects on global food insecurity. This is done in three essays by applying mathematical programming. In the first essay, a modeling study is done on optimal temporal investment between climate change adaptation and mitigation considering their relative contributions to damage reduction and diversion of funds from consumption and other investments. To conduct this research, we extend the widely used Integrated Assessment Model?DICE (Dynamic Integrated Climate Economy) adding improved adaptation modeling. The model results suggest that the joint implementation of adaptation and mitigation is welfare improving with a greater immediate role for adaptation. In the second essay, the research focuses on the ground water dependent agricultural economy in the Texas High Plains Region. A regionally detailed dynamic land allocation model is developed and applied for studying interrelationships between limited natural resources (e.g. land and groundwater), climate change, bioenergy demands and agricultural production. We find out that the effect varies regionally across hydrologically heterogeneous regions. Also, water availability has a substantial impact on feedstock mix. In terms of biofuel feedstock production, the model results show that limited water resource cannot sustain expanded corn-based ethanol production in the future. In the third essay, a Computable General Equilibrium (CGE) model is applied in an attempt to study potential impacts of climate change on global food insecurity. Our results show that climate change alters the number of food insecure people in a regionally different fashion over time. In general, the largest increase of additional food insecure population relative to the reference case (no climate change) is found in Africa and South Asia, while most of developed countries will benefit from climate change with a reduced proportion of food insecure population. In general, climate change affects world agricultural production and food security. Integrated adaptation and mitigation strategy is more effective in reducing climate change damages. However, there are synergies/trade-offs between these two options, particularly in regions with limited natural resources.
