Water Conservation Initiatives in Metro Phoenix: A Sustainable Development Goals Perspective

Metro Phoenix is adopting innovative water conservation strategies aligned with the United Nations Sustainable Development Goals (SDGs), particularly SDG 6 (Clean Water and Sanitation), SDG 11 (Sustainable Cities and Communities), and SDG 13 (Climate Action). The region is transitioning from traditional green lawns to xeriscaping, promoting sustainable water use amid rising temperatures and prolonged droughts.
