There are many activities carried out in parks, gardens, and other green fields of municipalities. Since these green fields are public areas, both employees and passers-by are confronting with hazards and risks of the performed activities. Therefore, it becomes even more important to determine the risks that may arise and take precautions. Landscaping and horticultural services include mostly human-driven activities than automated ones. The main objective of this study is to analyze human factors and procedural failures in landscaping and horticultural services by using Hazard and Operability (HAZOP) methodology. In this scope, landscaping and horticultural activities of a metropolitan municipality were examined in four main topics as; green field services, cleaning services, construction and maintenance services, and auxiliary works. Firstly, guide words were determined and then deviations were detected by using the guide words for each activity. Possible causes and consequences of the deviations, existing barriers, and proposed improvements were determined. Findings showed that unsafe behaviors of employees, noncompliance of workplace regulations and unawareness of chemical, electrical, and biological hazards cause the maximum number of failures among other factors. This study could be used by any landscaping and horticultural service provider for analyzing human and procedure-related failures in landscaping and horticultural services.

The purpose of this thesis is to assess boundary and category changes in Turkish national parks, to try to understand the reasons behind such changes, and to develop recommendations. Such changes between 1959 and 2019 were identified by examining official ...
