Water-efficient urban landscaping using indigenous Gulf plants
Native Plants for Urban Landscapes in Qatar
The project aims to identify, propagate, and evaluate indigenous desert plant species suitable for urban landscaping in Qatar and other GCC countries. It seeks to reduce freshwater consumption in cities by replacing conventional ornamental plants with native species adapted to arid, calcareous soils.
A further objective is to demonstrate large-scale nursery and street-level performance of these plants under local climatic conditions. The project also aims to support sustainable urban development frameworks such as the Qatar Sustainability Assessment System. Finally, it promotes conservation of native plant heritage while enhancing urban biodiversity.
Methodology
Conventional seed germination and nursery propagation techniques were used to establish indigenous plant species under shad-house conditions. Successfully propagated species were transferred to demonstration sites to assess growth, flowering, and survival under real urban and street conditions. Water use efficiency was monitored and compared against conventional ornamental plants. Plant performance was evaluated in native calcareous soils without the use of fertilizers or pesticides.
Data from nursery and field trials were compiled to develop practical guidelines for large-scale urban landscaping applications. Knowledge outputs were structured for dissemination through a dedicated illustrated book.
Outcomes
More than 100 indigenous plant species were successfully germinated and grown to the flowering stage, demonstrating strong adaptation to Qatar’s soils and climate while requiring only about 30% of the irrigation water used by ornamental plants. The project established a viable pathway for sustainable urban greening with minimal maintenance, no fertilizer or pesticide inputs, and reduced environmental impact. Key outcomes include improved water conservation, enhanced urban habitats for native flora and fauna, and strengthened alignment with national sustainability goals.
