Xeriscaping feasibility as an urban adaptation method for global warming: A case study from Turkey

Abstract

Green spaces are of great importance in the image of a city. But water resources are gradually decreasing due to the increase in world population, climate change related to global warming, unconscious consumption of water resources, and pollution. In landscaping, incorrect plant choices and the use of grass in expansive areas may also increase pressure on limited water resources. In summer, scenes of yellow, dry, and even dead landscaping designs are increasingly common where correct landscaping designs are not employed. This study consists of data collected to obtain a better understanding of the study area, Antalya/Konyaalti, regarding its natural features and xeriscape, and a cost estimate of construction and maintenance of a proposed design project. It was prepared taking into consideration the existing landscape design and the xeriscape principles of the pilot park. Results were compared in terms of economic and environmental contributions. From the perspective of the literature review to date, this study is one of the first aimed at determining the construction and maintenance costs of xeriscape practices to be conducted on a park scale in the context of public spaces nationally and internationally. The potential benefits of the xeriscape in Mediterranean conditions have been quantitatively and qualitatively demonstrated. Recommendations are made for the redesign of the existing park based on xeriscaping, which could save 57.24% of the construction costs and 54.91% in annual maintenance costs. We conclude that xeriscaping can contribute to ecology by providing water savings, reducing chemical use, and preventing soil pollution.
