Buddha Nullah or Buddha Nala (Punjabi: ਬੁੱਢਾ ਨਾਲ਼ਾ) is a seasonal water stream, which runs through the Malwa region of Punjab, India, and after passing through highly populated Ludhiana district, Punjab, India, it drains into Sutlej River, a tributary of the Indus River. Today, it has also become a major source of pollution in the region as well the main Sutlej river, as it gets polluted after entering the highly populated and industrialized Ludhiana city, turning it into an open drain. Also, since large area in south-western Punjab solely depend on the canal water for irrigation, and water from Buddha Nullah enters various canals after Harike waterworks near Firozpur, thus affecting far-reaching areas such as Malout, Zira, upper Lambi, while the areas being fed by Sirhind feeder, are the most-affected by its pollution.[1]
In 2006, a Ludhiana-based human rights organization, filed a case regarding the state of this nullah in the Punjab State Human Rights Commission (PSHRC) and even invited environmentalist, Balbir Singh Seechewal, who had earlier cleaned the 164-km-long highly polluted Kali Bein rivulet with the help of his followers and without the government aid, to take the cause of cleaning up the nullah.[2]
A study conducted by Punjab Agricultural University in 2008, revealed presence of toxins and heavy metals in the food chain due to use of its water, to cultivate vegetables and other crops.
This was followed by another study by the School of Public Health, Department of Community Medicine, PGIMER, Chandigarh, and the Punjab Pollution Control Board (PPCB), which also showed heptachlor, beta-endosulphan and chlorpyrifos pesticides in concentrations exceeding the maximum residue limit in samples of ground and canal water used for drinking, the pesticides were also detected in fodder, vegetables, blood, bovine and human milk samples, indicating that these have entered the food chain due to the use of agricultural run-off and irrigation of field with drain water. With increasing poisoning of the soil, the region once hailed as the home to the Green Revolution, now due to excessive use of chemical fertilizer, is being termed the "Other Bhopal", and "even credit-takers of the Revolution have begun to admit they had been wrong, now that they see wastelands and lives lost to farmer suicides in this "granary of India".[3]
