Urbanization has increased demand for water and impaired aquatic ecosystems, threatening water resources worldwide. Climate change and more frequent droughts are expected to exacerbate this situation. Residential landscaping, especially lawns, are a major factor in increasing domestic water use.

Outreach efforts have been made to promote outdoor residential water conservation and promote methods that provide ecosystem benefits. These include water harvesting using rain barrels, infiltrating storm water using rain gardens, and landscaping with native plants.

Municipalities worldwide are showing substantial interest in urban greening, defined here as the introduction or conservation of outdoor vegetation in cities. In many cases greening involves substantial tree planting, and across the United States cities have established ambitious canopy cover goals and major tree planting programs.
