Aydin, M.; Koc, P.; Tumay, M.
The aim of this study, which covers the period from 1991 to 2017, is to analyze the relationships between recovered paper consumption, human development index, urbanization rate, and forest footprint in the framework of the Environmental Kuznets Curve (EKC) hypothesis in the 10 countries that consume the most recovered paper. Considering that wood is the raw material of paper, the study investigates whether the increase in the consumption of recovered paper has a positive effect on the forest footprint. Therefore, unlike other studies, the dependent variable of the EKC model is the forest footprint. The study is original in that it is the first to analyze the effects of recovered paper consumption on environmental degradation in the context of the EKC hypothesis. To analyze the relationships between the variables, we use panel cointegration tests based on AMG and CCE estimators, which allow analysis on both a country and group basis. According to the results, the EKC hypothesis is valid only in the Netherlands. While there is a statistically significant and negative relationship between recovered paper consumption and forest footprint in the Netherlands, there is a statistically significant and negative relationship between urbanization and forest footprint in Italy. Economic and ecological benefits and costs must be considered to measure the net benefit of waste management programs. In addition, to analyze how environmental impacts change over time, ecological footprint and gas emissions during waste generation or disposal should be measured similarly to carbon emissions.

Sivrikaya, Fatih; Çakir, Günay; Akay, Abdullah Emin
Land use/cover change impacts ecosystem services and functions such as forest health, biodiversity, and water production. Monitoring and assessing land use/cover changes provides an effective and accurate evaluation of human impact on the forest ecosystems. This study aims to determine spatial and temporal changes in land use/cover at a particular time period in a typical forest ecosystem of Turkey using geographical information systems (GIS). Specifically, the objective of this study is to analyze the main factors driving land use/cover change and the impacts of such changes in local and global perspective. Results showed that the total forested areas decreased from 5089 ha (41% of the study area) to 4426 ha (36% of the study area) during a 21 year period, which figures a net decrease of 663 ha (5%) forest areas and the average annual deforestation rate was 32 ha. Conifer forest (161 ha) completely transitioned to other cover types over 21-year period. Three major factors including distance from villages, distance from roads, and ground elevation were considered in evaluating forest disturbance. The results showed that these factors influence the reforestation/deforestation rates. Besides, forest disturbance was found to be closely related to distance from villages, distance from roads, and elevation.
