“Creating more green cover through large-scale tree plantation is the most effective way to tackle rising temperatures caused by global warming,” S.L. Madivalar said in Dharwad on June 7.

The professor was speaking after inaugurating a cleanliness drive and sapling plantation programme organised by the Parisarakkaagi Naavu Sanghatane, in association with the State Pollution Control Board, at Gandhi Shanti Pratishthana.

“Increasing levels of carbon dioxide in the atmosphere are contributing to climate change and irregular weather patterns, leading to crises in agriculture and other sectors. He explained that carbon dioxide traps heat by preventing reflected solar radiation from escaping into space, thereby increasing global temperatures. People living in slums and economically weaker sections are suffering the most from rising heat, as they lack resources to protect themselves from extreme weather conditions. Forests, oceans and wetlands absorb large quantities of carbon, but their extent is shrinking every year. Hence, expanding green cover and protecting natural ecosystems have become essential,” he said.

Deputy Commissioner Snehal R. planted a sapling in front of Gandhi Shanti Pratishthana.

Senior Environmental Officer I. H. Jagadish said nearly 450 tonnes of waste was generated daily in the twin cities of Hubballi-Dharwad, making scientific disposal a major challenge.

He said new solid waste management rules came into force on April 1, 2026, following Supreme Court directions. Besides separating wet and dry waste, households must now further segregate dry waste into recyclable categories, such as paper, plastic and metal.

Mr. Jagadish said that sanitary waste, including diapers, sanitary napkins and bandages, must be treated as biomedical waste, while items such as chemical containers, bulbs and paint cans should be classified as hazardous waste.
