Stubble Burning and Pollution: ICAR Warns of Irreparable Damage to Soil and Air Quality

Stubble Burning and Pollution: ICAR Warns of Irreparable Damage to Soil and Air Quality

Breaking News, Environment
As Delhi continues to choke under hazardous air pollution senior scientists from the Indian Council of Agricultural Research (ICAR) have raised alarms about the dual damage caused by stubble burning—not only polluting the air but also depleting vital soil nutrients. Nutrient Loss and Soil Degradation ICAR scientists revealed that burning one tonne of paddy stubble results in a significant loss of soil nutrients, including: 12-13 kg of phosphorus 35 kg of potassium 20 kg of nitrogen Of these, nitrogen is completely lost, while phosphorus is partially recoverable. ICAR Director General Himanshu Pathak emphasized that stubble burning harms both the environment and agricultural productivity, stating, “In any form, stubble should not be burnt as it harms everyone.” Rising P...
Can Cloud Seeding Help Delhi Breathe Cleaner Air?

Can Cloud Seeding Help Delhi Breathe Cleaner Air?

Breaking News, Climate Actions, Environment, Learning & Developments
Delhi is grappling with its annual air pollution crisis, with Air Quality Index (AQI) levels in the “severe plus” category, consistently above 450. In response, Delhi’s Environment Minister Gopal Rai has appealed to Prime Minister Narendra Modi for assistance in deploying cloud seeding a controversial technique to induce artificial rain and potentially reduce pollution levels. What is Cloud Seeding? Cloud seeding, also known as artificial rain, involves dispersing substances like silver iodide, potassium iodide, or dry ice into clouds to stimulate precipitation. These particles act as nuclei around which water droplets form, potentially triggering rainfall. The process can be carried out via aircraft, rockets, or ground-based generators. In theory, the rainfall generated could "wa...

Gurugram High Rise Conducts Artificial Rain to Tackle Worsening Air Pollution

Breaking News, Climate Actions, Environment
In a proactive response to the severe air quality crisis gripping Delhi NCR, authorities implemented “artificial rain” in Gurugram’s DLF Primus high-rise complex in Sector 82. Sprinkler systems and fire lines at the top of the 32-story buildings were used to release water, creating a rainfall effect aimed at reducing air pollution levels. The Resident Welfare Association (RWA) President of DLF Primus, Achal Yadav, stated, “This artificial rain initiative is our effort to curb pollution in the area. If AQI levels continue to rise, we’re ready to make this a daily measure.” Additional efforts, such as encouraging carpooling, are also underway to address the ongoing air quality issues. A video from the site shows light rainfall from the high-rise towers, clearing the skies and helping r...

Crores of Premature Deaths Linked to Air Pollution in India Over Four Decades

Breaking News, Climate Actions, Environment
A comprehensive study led by researchers from Singapore's Nanyang Technological University (NTU) has revealed that air pollution from fine particulate matter (PM2.5) has been linked to approximately 2.61 crore premature deaths in India between 1980 and 2020. This makes it one of the most extensive studies on air quality and climate, utilizing 40 years of data to assess the health impacts of PM2.5. According to the study, the average life expectancy in India has been significantly reduced due to conditions caused by PM2.5 pollution, such as strokes, heart and lung diseases, and cancer. The study also noted that weather patterns have exacerbated the impact of pollution, increasing the death toll by 14%. “Asia was estimated to have the largest number of PM2.5-attributable premature deat...
