Across cities, official Air Quality Index (AQI) readings often overlook local hotspots. Chennai has eight Continuous Ambient Air Quality Monitoring Stations (CAAQMS) that function 24/7 throughout the year. But this isn’t enough to map particulate matter. Air changes every few metres, as researchers from the Indian Institute of Technology-Madras tell us. Seasonal variation, construction, vehicular movement, and proximity to industries also change the air we breathe, In 2022, over 17 lakh people died in India due to air pollution (PM 2.5), according to a Lancet study. With better hyper-local air data and public awareness, citizens and policymakers can target pollution…

I have couple of suggestion to add. In many apartment complexes, the cost of water (whether due to tanker supply or bore water or Cauvery) is a shared cost. This cost is normally recovered as a part of maintenance fee from residents, which is normally a function of area of the individual apartment. There is *no* billing based on actual usage.
If we want to start looking at water as a precious resource, we need to also enforce metering and charging based on usage, at an individual apartment level. Otherwise, it will be a tale of tragedy of commons – with no incentive for reduced water usage/wastage and no penalties for excess usage.
For usage of bore-wells and rain-water harvesting, again similar principles should be applied. Water drawn from bore-well must be charged on metered basis (at a cost lesser than what is charged for Cauvery) and rain-water harvested should be rewarded monetarily (similar to how one can earn money today by supplying solar power to the grid).
We need to rejuvenate all the lakes in and around Bangalore some more lakes which are large and can help us with quenching the water issue if we dont act now this city will be a ghost city without water.
