Indigenous communities have long used techniques to conserve water. Stepwells (baolis), check dams, rainwater harvesting pits and tanks store monsoon water. Contour bunds on slopes slow runoff and let water seep into the soil. These systems recharge groundwater naturally. They are low-cost, community-friendly and environment-friendly solutions that modern water management systems can learn from and implement widely.

Punjab became the center of India’s Green Revolution in the 1960s. Farmers switched from diverse crops to mainly wheat and rice, using chemical fertilizers, pesticides and tube well irrigation. Though food production increased, it also led to soil degradation, water depletion and pesticide-related health issues. The initial success brought long-term challenges, showing the need for sustainable farming practices today.

Punjab’s Green Revolution relied on high-yield crops needing lots of water. Farmers used deep borewells and tube wells extensively, especially for rice. Without enough rainfall or recharge systems, groundwater wasn’t replenished. Over decades, the water table dropped drastically, making farming unsustainable. The situation is now critical, with more than 75% of districts declared as over-exploited in water usage.

Pesticides used to protect crops from pests often stay in soil, water and food. Long-term exposure to these chemicals can cause cancer, breathing problems, reproductive disorders and nerve damage. Farmers, especially those without protective gear, face high risks. Contaminated food and water affect consumers too. Awareness, regulation and organic alternatives are necessary to reduce these harmful health impacts.
