Expansion of urban green spaces in the low water area on the idea of arid landscape (Xeriscape)

Urban green spaces considerably affect physical and mental health of citizens. Nowadays, due to global warming and limited water resources, the area of green spaces in the cities is limited. Xeriscaping is a suitable approach to create green spaces in the regions that are increasingly face to drought or for the regions with hot and dry climate such as Iran. In general, Xeriscaping is the art of designing green space in the dry regions. Creation of green space landscapes with saving more water and protecting environment is the main objective of this approach. Xeriscaping can be a suitable replacement for traditional gardening in dry regions. It has several advantages such as: increase in water supply for other urban consumptions, time and money saving, decrease in chemical consumptions and decrease in environmental pollution. In Xeriscaping by using special plant pattern and water use efficient plants, we can save water up to 50% without any decline in aesthetic aspects of the environment. Since Iran is a dry country, Xeriscaping can be recommended for creation of green space in many regions in the country.
