water scarcity in the world

What makes up Freshwater?

In simple terms, freshwater is water that has little or no dissolved salts and dissolved solids. This excludes sea or marine waters and brackish water. All over the world, water comes in other forms such as ice-sheets, glaciers, lakes, ponds, rivers, streams and icebergs. The quantities found in every geographic area may vary.

Fresh water may be still or fast flowing. Still, fresh water is known as ‘Lentic systems’ whiles flowing fresh water is known as ‘Lotic Systems’. Others come from underground as groundwater in aquifers and underground streams.

Where does all fresh water come from?
Fresh water comes from precipitation from the atmosphere, usually in the form of rain, mist and snow. When these fall, they find their way into streams and rivers which run down from mountain tops to low-lying areas. Eventually, they end up in the sea or ocean. Because much of atmospheric water end up falling into our water bodies, it is important that we keep an eye on the chemicals that find their way into the atmosphere via air pollution.

But how does water end up in the atmosphere in the first place? This can be explained by a model called The Water Cycle.
