Causes of water scarcity

Here are some important causes of water shortage:

water scarcity infoPopulation expansion
Just 50 years ago, the total number of people on earth has doubled and continues to grow. This is a result of larger family sizes and access to better health care and lifestyles. This means that use of wholesome water for drinking, cleaning, cooking and sewage has tripled. Humans are a lot more careless in recent time, and we waste more water than ever before. This has placed a lot of pressure on the same amount of water that we have.

water scarcity infoUrbanisation
Cities are growing and expanding more than ever before. Cities also tend to hold more people than towns and villages. This means there an increased need to take care of sewage, cleaning, construction and manufacturing.

water scarcity infoPollution
pollution threatens water
Water, air and land pollution together contribute to the reduction of water quality. Sewage, oil discharges from industries, waste dumping into water bodies, radioactive waste from mining activities as well as dirty water fro sanitation work in hospitals, hotels, oil companies, mining, schools and restaurants all end up polluting our waters. Water contamination and wastage from some mining industries through Hydraulic Fracturing (fracking) has also been a worry for many people. Click here to learn more about Fracking.

water scarcity infoVegetation destruction and Deforestation
Trees help prevent excessive evaporation or water bodies. They also enrich and condition the climate. This means the destruction of forests by fire, logging and farming have exposed soil moisture and water bodies to the sun’s intense heat, leaving them dried out.

water scarcity infoClimate change
All over the world, places that used to have lots of rainfall do not have enough again and dry places suddenly are getting colder and wetter. Both cases result in clean water shortage because less rainfall means less water, and excessive rains cause flooding and which brings all sorts of debris and destroy water treatment installations.
