Sustainable development is a concept that has started gaining importance in recent years. It helps reduce the environmental impacts of cities with dense human populations. On a smaller scale, social spaces, localities and institutions can be—in many ways—accurately representative of the cities they’re in. In other words, a place like a university campus can be considered a small city. Based on this point, this study was conducted to calculate the ecological footprint (EF) of Eskisehir Technical University (ESTU) campus and to determine the effects of the campus on the environment. The EF of the previous, current and future land use types within Iki Eylul Campus of ESTU was calculated using GIS software. The results showed that the major land use and land cover types in the study area were pasture, agricultural land and natural plant patterns in 1990, and most of them were converted into built areas—including the campus building. The change in EF due to this land use and land cover change was determined to be approximately 148,85 gha. However, when the land use and the campus user data for 2018 were included into the process, the EF of the study area was found to be 251,251.3 gha. Regarding the new structures and increase in the number of users in accordance with the campus development plan, it was determined that the EF of the campus area—barring any preventive actions—would reach 541,898.8 gha in the future. The current EF was calculated based on the artificial surfaces, energy consumption, transportation, waste production information; and determined that the highest EF value related to the electricity consumption. The total EF value of the campus in 2018 was 1148.2 gha.

Urban Atlas (UA) data covering the large urban areas have been produced by the European Environment Agency for a variety of European countries including Turkey since 2006. The use of the UA data for the determination of spatiotemporal land use and density changes in urban areas. UA data of Eskisehir, Turkey, were used in order to detect the spatiotemporal changes between 2012 and 2018. CORINE data–based change detection and NDVI analysis were also made and compared with the results obtained from the UA data. The results based on the UA data revealed that the artificial surfaces in the study area increased by 17.65% and there was a 18.32% increase in the total amount of agricultural lands, natural lands, forests, and vegetation. Although CORINE data–based analyses showed a similar trend in land use/land cover changes, the amount of changes between 2012 and 2018 in CORINE and UA data–based analyses were found to be 4.99% and 17.55%, respectively. A 9.30% mismatch between the UA changes and NDVI difference data was also calculated. Research findings revealed that the utilization of the UA data in the urban territories would be advantageous especially in planning processes to detect and compare the changes in the artificial and non-artificial surfaces and NDVI analysis would be very supportive to control and compare the results. It is also concluded that this study may be a useful model to monitor the cities in accordance with the 2030 and 2050 policies of European Council on Land Use, Land Use Change and Forestry.
