World needs ' greener ' water policies as demand rises
The world needs green water policies
Recent UN reports estimate that approximately 4 billion people — half the global population — experience severe water scarcity for at least part of the year. Additionally, 2.1-2.2 billion people lack access to safely managed drinking water.
Governments must prioritize "greener" water policies to improve supply and quality, as climate change, population growth, and retreating glaciers threaten water security for billions, according to United Nations reports.
"Roughly half of the world's population currently experiences severe water scarcity at least one month a year," states the UN World Water Development Report.
This could worsen without action, with projections warning of increased shortages by 2050 due to intensifying climate impacts on the water cycle — wetter areas getting wetter, drier areas drier.
Global water demand continues to rise by about 1% per year, driven by population growth, economic development, and changing consumption patterns, mainly in emerging economies.
Ecosystem-friendly solutions
Traditional "grey" infrastructure like dams and treatment plants is increasingly insufficient and costly. Nature-based solutions — such as wetlands restoration, soil moisture improvement, and groundwater recharge — offer sustainable, cost-effective alternatives.
"These solutions can act as regulators, cleaners, and water suppliers," experts note.
Examples show success:
New York City → saves over $300 million annually through watershed protection and farmer incentives.
China's Sponge Cities → now expanded beyond pilots, recycling rainwater via permeable surfaces and restored wetlands.
Green water management can boost agricultural production by up to 20%, reduce erosion, drought, and flood risks, while improving soil and biodiversity.
Yet, investment in nature-based solutions remains low, often less than 1% of total water infrastructure spending.
Urgent shift to greener policies is essential to avoid future water conflicts and ensure sustainable access.
