More than two billion people across the world lack adequate access to one of the essential elements of life: clean water. Although governments and aid groups have helped many living in water-stressed regions gain access in recent years, the problem is projected to worsen as the global population grows and climate change intensifies. Yet insufficient international coordination on water security has slowed the search for solutions. In a January 2026 flagship report, UN researchers warned that the world is in a state of “water bankruptcy,” in which human demand and depletion of natural water systems exceed replenishment rates. This threatens global energy and food security and potentially causes irreversible ecological degradation.
Water stress can differ dramatically from one place to another, in some cases causing wide-reaching damage, including to public health, economic development, and global trade. It can also drive mass migrations and spark conflict. As regions, particularly the Middle East and North Africa, become increasingly water-stressed, pressure is mounting on countries to implement more sustainable and innovative practices and to improve global water management cooperation. Experts say impacted countries must also account for the potential that watersheds—areas of land that channel rainfall, snowmelt, and runoff into a common body of water—may never return to their historical baselines, making sustained collaboration essential to meeting every country’s water needs.
