Where the World's Freshwater Is—and Why It’s So Uneven

Freshwater is essential for life, yet it’s surprisingly scarce. While our planet is covered in water, only about 2.5% of it is freshwater, and most of that is locked away in glaciers, ice caps, or deep underground. That leaves only a tiny fraction available in lakes, rivers, and reservoirs—where people, animals, and ecosystems rely on it every day.

But freshwater isn’t spread evenly across the globe. Some countries have an abundance, while others struggle with scarcity.Let’s take a look at where the world’s freshwater is concentrated, based on data from the World Bank, with a visualization created by Visual Capitalist to help illustrate it.

Fresh water in the world

Who Controls the Most Freshwater?

According to the data, just five countries hold over 35% of the planet’s renewable freshwater supply:

  • Brazil (13%) – Home to the Amazon Basin, which alone accounts for one-fifth of global river flow.
  • Russia (10%) – Holds vast freshwater reserves, including Lake Baikal, which contains 20% of the world's unfrozen freshwater.
  • Canada (7%) – Over two million lakes, including its share of the Great Lakes, make Canada a water-rich nation.
  • United States (7%) – Major river systems like the Mississippi and Colorado provide water for millions, though some regions face growing shortages.
  • China (7%) – While China has substantial freshwater resources, they are unevenly distributed, with the south receiving far more water than the drier north.

The Growing Pressure on Freshwater Resources

Freshwater availability is changing due to climate shifts, overuse, and pollution. Many regions are experiencing longer droughts, shrinking glaciers, and declining groundwater levels. Meanwhile, water demand continues to rise due to population growth and industrial use.

Countries that rely on seasonal rainfall or glacial meltwater are particularly vulnerable. For example, much of South Asia depends on rivers fed by Himalayan glaciers, which are retreating due to rising temperatures. In the U.S., aquifers in states like California and Arizona are being depleted faster than they can recharge.

Water scarcity is expected to become an even bigger challenge. As demand grows, conflicts over water rights could become more common, especially in regions where rivers cross national borders. To combat shortages, countries are investing in desalination, water recycling, and conservation efforts—but solutions need to scale quickly to meet rising needs.

Freshwater is more than just a human necessity—it supports entire ecosystems. Wetlands, forests, and grasslands all depend on water to sustain biodiversity. When freshwater sources shrink, so do the habitats for countless species.

    How can this be true if the Great Lakes contain 20% of the freshwater on Earth?

Find cities with similar climate

This map has been created using The Global environmental stratification. The Global environmental stratification (GEnS), based on statistical clustering of bioclimate data (WorldClim). GEnS, consists of 125 strata, which have been aggregated into 18 global environmental zones (labeled A to R) based on the dendrogram.

Mapping the Hottest Temperatures Ever Recorded on Earth

 When summer arrives, it brings not only vacation season but also some of the most extreme heat waves across the globe. While many people associate summer with warm, sunny days, some regions endure scorching temperatures that push the limits of human endurance. To put these extremes into perspective, we’ve mapped the highest temperatures ever recorded in countries around the world. The maps below, created by Vivid Maps , illustrate these record-breaking temperatures and the patterns of extreme heat across the globe. The Hottest Temperature on Record According to historical weather data, the highest reliably recorded temperature on Earth is 56.7°C (134°F) , measured in Death Valley, California , on July 10, 1913 . However, an even higher temperature of 58°C (136.4°F) was reportedly recorded in El Azizia, Libya , on September 13, 1922 . While this Libyan record stood for decades, some meteorologists have questioned its accuracy due to inconsistencies in measurement methods at the ti...

How Cold Can It Get? The Lowest Temperatures Ever Recorded, Mapped

We often talk about record heat , especially in the context of climate change. But on the flip side, our planet also experiences cold so extreme it defies belief—temperatures that can flash-freeze exposed skin and halt life as we know it. These are not just numbers on thermometers; they’re snapshots of how Earth's atmosphere behaves under specific conditions—altitude, wind patterns, and location far from the moderating effects of oceans. The coldest temperature ever recorded on Earth? That title goes to Vostok Station in Antarctica, where scientists measured a bone-cracking −89.2°C (−128.6°F) on July 21, 1983. Located on the East Antarctic Plateau, Vostok is more than 1,000 kilometers from the South Pole and sits atop about 3.7 kilometers (2.3 miles) of ice. It’s isolated, dry, and high—three ingredients that make for perfect deep freeze conditions. The world map below created by VividMaps shows the lowest temperature ever recorded by country.
