This indicator says a country or region experiences "water stress" when annual water supplies drop below 1,700 cubic meters per person per year. [31] Levels between 1,700 and 1,000 cubic meters will lead to periodic or limited water shortages. When water supplies drop below 1,000 cubic meters per person per year the country faces "water scarcity".
Water scarcity poses a threat to ecosystems and biodiversity, primarily through its impact on aquatic habitats, rivers, wetlands, and lakes. [3] Decreased water flows and the drying of water bodies disrupt the delicate balance of ecosystems, affecting a range of species including fish, amphibians, and water-dependent plants, experience habitat loss and fragmentation, affecting their ...

Share of the population without access to an improved water source, 2020. Global access to clean water is a significant global challenge that affects the health, well-being, and development of people worldwide. While progress has been made in recent years, millions of people still lack access to safe and clean drinking water sources.
Climate factors have a major effect on water security as various levels. Geographic variability in water availability, reliability of rainfall and vulnerability to droughts, floods and cyclones are inherent hazards that affect development opportunities. These play out at international to intra-basin scales.
Topsoil runoff from farm, central Iowa (2011). Water pollution in the United States is a growing problem that became critical in the 19th century with the development of mechanized agriculture, mining, and manufacturing industries—although laws and regulations introduced in the late 20th century have improved water quality in many water bodies.
