Today, groundwater usage in India is the highest in the world. It’s about double the usage in the United States. Lall said that by 2025, many parts of India could run out of groundwater, and face a water crisis. So groundwater levels are dropping. Dr. Lall explained that India has been using groundwater to support agriculture for its growing population. He added that pumping water from the wells requires the use of fossil fuel whose carbon dioxide emissions contribute to climate change. So this scenery is a grand problem across energy, CO2 emissions, agricultural food security, and water, in a region which has 1.5 billion people today, and by 2050 is projected to hit greater than 2 billion people. That’s the scary part. Lall’s work involves finding solutions. We have to come up with economic ways of shifting what these people grow and charging them for the use of the water, so that they end up with still positive incomes but more responsible water use.
