Today is (was, in India) the World Water Day, an initiative that grew out of the 1992 United Nations Conference on Environment and Development (UNCED) in Rio de Janeiro. The world has changed significantly since 1992. Cities are bigger and more polluted. Rivers are not rivers anymore. Drinking water has become a luxury in developing countries. Harmful affluents are polluting our seas everyday. Yet, the spirit of fighting against everything that is wrong and that needs to change, continues to grow stronger and bring hope to people.

In 1992, the daily newspaper and word of mouth were probably the only main sources of information. Today, with information technology and Google Maps in place, you can just go to this link and find out about all Water events happening around the world today. I was on tweeting a lot today and believe me, the last time I had seen these many conversations around a topic was back in December during the COP15 summit in Copenhagen.

Here are some interesting facts I found on Twitter today –

  • Every day, 2 mn tons of sewage and other effluents drain into our world’ waters, including some of ours.
  • Groundwater accounts for about 80% of domestic water requirement and more than 45% of the total irrigation in India.
  • One needs abt 30-50 liters/day but dripping joint wastes about 76 litres of water/day

Water has always been synonymous with life itself and the current water crisis around the world has reinstated its importance in our lives. Yes, we need better purification technologies, better distribution systems and low cost supply for the unprivileged sections. But most importantly, for those of us who have the luxury to use as much as water as we want to, we need to responsible in how we do that.

Here are some quick tips for conserving water –

  1. Be a responsible individual (don’t waste water while brushing, shaving but letting the water run while you lather, check for leaking taps etc) – Remember there are a number of ways to save water and they all start with YOU
  2. Plant and maintain trees. An increased tree cover would translate into a lot of benefits like reducing run off, increasing percolation and recharging the groundwater reserves.
  3. Install rainwater harvesting systems in your home, school, college, workplace etc.
  4. Treat waste water properly so that it doesn’t end up polluting the rivers. (Almost 60% of the pollution of River Yamuna in New Delhi is from domestic sources and almost 90% of the pollution in river Ganga in the city of Varanasi is from domestic sources)
  5. Share this with others and spread awareness

Once again. Save Water. Save the world.

A recent article in Times of India said that groundwater extraction in northern parts of India is the highest in the world and contributes to as much as 5% rise in the global rise in sea levels. The average depletion of groundwater level in this region is an alarming 10 cm every year; Delhi, Rajasthan, Punjab, Haryana and Uttar Pradesh leading this misuse. Interestingly, this region is host to 10% of humanity, which makes the scenario very scary. A study found that the net loss of water was around 25 trillion litres an year.

Climate change also contributes to groundwater depletion but the issue here is the uncontrolled use of groundwater by the citizens where on the other hand, Mumbai is facing severe water cuts. In this context, access to clean water and skills of water management and education are becoming increasingly important!
