Modification of Green Space Planting Pattern Based on the Principles of Xeriscaping to Reduce Water Consumption in Metropolitan Areas

Water scarcity has been one of the biggest problems in human life for several decades. , Therefore, planning and managing water consumption is essential to minimize the problem of drought. However, without considering the issues, principles, and patterns suitable for the climate of each region, designing urban green spaces would be inefficient. One of the first views created based on sustainable principles is xeriscaping. In recent decades, experts, especially landscape architects have shown interest in xeriscaping, an old approach with a new name, to recover the environmental components of urban landscapes in the face of reducing water consumption and drought. In this regard, this research has sought to find solutions and strategies for xeriscaping and its effectiveness in reducing water consumption using analytical-descriptive methods and an intensive review of the theoretical literature on xeriscaping indicators. For this purpose, first, the literature on the characteristics of xeriscaping was reviewed, then three successful global projects were scrutinized to extract the drought-resistant solutions and measures. Finally, Several responsive measures have been presented to reduce water consumption. The results of this study show that xeriscaping as a suitable strategy can be an alternative to high water-using landscaping.
