Almost 97% of Earth's water is saltwater - found in the oceans and other saline sources - which is unsuitable for drinking and irrigation. This leaves only 3% for freshwater.
Imagine winning $100 in a radio contest, but only being allowed to spend 3% of the money. In other words, you can only spend three of the 100 dollars. Three percent isn't very much, but it represents all the freshwater on Earth. Unfortunately, almost 70% of freshwater is frozen solid in glaciers and ice caps. About 29.7% of freshwater is underground or in the atmosphere. The remaining 0.3% is in lakes and rivers.
From space, Earth looks like a blue planet because it has so much water. But, the availability of Earth's freshwater varies greatly by location and economic conditions. Over one billion people lack the freshwater required to meet basic human needs. Sometimes, freshwater is limited by climate or geography, which causes physical scarcity. Politics and finances can also limit water, which causes economic scarcity. Many countries in Africa are afflicted with economic scarcity.
