A high percentage of green spaces<br />create lawns, which are high water consumer landscapes. Due to the environmental, recreational and<br />athletic values of lawns, they are considered as non-removable elements in urban green space development.<br />This paper reviews and discusses strategies for efficient water usage in lawn areas using library study<br />methods. According to the results, first, it was recommended that water demands of turfgrasses are<br />calculated using precise scientific methods. Eleven strategies including selecting appropriate plant species,<br />clipping from appropriate height, removing the thatch layer, using wastewater as an irrigation water source,<br />the use of superabsorbents, application of regulated deficit irrigation, the use of subsurface irrigation<br />systems, replacement of lawns with appropriate ground cover plants, the use of surfactants and other<br />chemicals such as paclobutrazol and endophyte fungi, as individual or combined strategies were suggested<br />for efficient water usage in turfgrass areas. These results, in some cases, can be used as executive<br />guidelines by green space professionals in order to reduce water usage in this sector and in other cases,<br />they can be used as preliminary studies for research in the field of sustainable management of turfgrasses in<br />arid and semi-arid areas. https://jdesert.ut.ac.ir/article_56484_f1e8404574750eeb8eb311d25811a7ec.pdf
