How did Punjab’s farming shift during the Green Revolution?
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 hRead more
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 unsuRead more
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.

See lessWhy is long-term food security threatened in Punjab?
Punjab’s over-dependence on water-intensive crops like rice, along with heavy use of fertilizers and pesticides, has degraded soil and drained groundwater. This makes the land less fertile and farming unsustainable. As natural resources decline, crop yields may fall, threatening food supply not justRead more
Punjab’s over-dependence on water-intensive crops like rice, along with heavy use of fertilizers and pesticides, has degraded soil and drained groundwater. This makes the land less fertile and farming unsustainable. As natural resources decline, crop yields may fall, threatening food supply not just in Punjab but across India. Crop rotation, sustainable practices and water conservation are essential for future food security.
