Maharashtra

• different regions experience varied level of water stress
• Rain Shadow Effect
  • monsoon winds becoming moisture-less
    • Marathwada
      • unsustainable crops ➡️ sugarcane
      • regur soil (clayey black soil)
        • retains moisture, but no low infilteration rate
          • Water Logging
    • North Karnataka
  • climate change

Developing water resilience

• Watershed management
• silt trapping mechanism
  • surface runoff
  • my MNREGA workers
  • farmers to do periodic desilting
• sustainable cropping
