Clean, safe water is a resource that many people take for granted. Millions of people daily purchase reasonably priced bottled water; tap water is often used for washing, cleaning and other purposes, without thought as to how much is being used, where the water is returned, whether water is treated for reuse, or that it could run out.
Health and environmental experts consider the current and future status of our water supply to be one of the principal global risks this year, and in the next few decades. Water security challenges, ranging from misuse to increased urbanization, climate change, and pollution, have threatened many countries’ Millenninm Development Goals. Technology, poor access, geopolitical interference, and pricing controls contribute heavily many worldwide lack the ability to treat water for.
Considerable concerns exist over Potential threats to water sources and effective water delivery. Many countries and non-governmental organizations are looking for solutions to the problems of water security, which are only expected to unless intervention and innovation takes place now.
Water Security and Threats
“Water Security” refers to the availability of safe water, per person, per annum, as well as the percentage of a given population that has access to improved water sources, according to many environmental groups and authorities. Safe water is considered to be free from frequent or consistent pathogens that are responsible for severe human diseases, chemicals, or radiological threats. Water can become “insecure” through the misuse of freshwater resources, exponential urbanization, climate change, pollution, infrastructural failure, or lack of economic support.
In 2015, reports showed that 1.3 percent of the total global freshwater supply came from surface water – including rivers, streams, and reservoirs – and 30.1 percent is stored under the earth’s surface, in aquifers. The remaining 68.6 percent is found in the polar icecaps and glaciers, and is inaccessible to the majority of the world’s population.
