Water Scarcity and Water Conservation - II
In the previous story, we’ve seen water scarcity in terms of quantity.
Let’s now understand the qualitative aspect of it.
To meet our daily water needs, water should be available in sufficient quantity and should also be of good quality.
So, in a region, even if water is readily available, but is not good enough for use, it will still be counted as water scarcity.
This may result when water bodies like lakes and rivers are polluted and their water becomes unfit for use.
There are instances where domestic wastes are dumped in lakes and rivers, thus polluting these freshwater sources.
Water bodies are also polluted by dumping industrial wastes, chemicals, pesticides and fertilisers from agriculture.
Many rivers in India have turned into toxic streams because of their irresponsible and excessive use for domestic purposes.
Underground water too is polluted in many areas because of chemicals used in farming or dumping of wastes in land-fills.
Overpopulation, agricultural modernisation, urbanisation and industrialisation have contributed to water scarcity.
In addition to these, natural calamities like floods and earthquakes also end up polluting water sources.
Need for Water Conservation
Water is a critical resource in our daily lives. Water is life.
So, conserving and managing our water resources is the need of the hour.
Conserving water means avoiding its overuse and protecting it from pollution.
Water conservation will keep us protected from health hazards that result from drinking or using polluted water.
It will also ensure that there is enough water available for agricultural irrigation, thus ensuring food security.
It will also help protect our natural ecosystems.
For instance, if we keep our lakes and rivers clean, fishes and organisms living in them will survive.
