As the saying goes, 'Necessity is the Mother of Invention' - A temporary ban on firecrackers by Indian Supreme Court, an appeal to scientisits from Dr. Harsh Vardhan (Union Minister of Environment, Forest and Climate Change, GOI) to develop e-firecrackers and social campaigns against their use due to environmental concerns, has driven a team of scientists from Indian Institute of Science Education & Research (IISERM) led by Prof. Samrat Ghosh (Chemical Sciences) to innovate and develop 'green' firecrackers that are safer, smoke-free and reusable. Prof. Samrat says, 'I have filled combustible material in the disposable bottle. This material is ignited with a source, like a spark. The launcher ignites the material which burns and generates pressure, pushing the bottle upwards, like a rocket. This is one of the safest methods of bursting crackers. In the community where I have tested this, even four-year-old kids feel comfortable operating this. Additionally, the combustive recipe in the device is very benign and not at all harmful for the user and the environment.' Regarding additional usage of the invention, Prof. Samrat says, 'From driving away animals in agriculture fields to airports using them to clear runways, the device is beneficial in many different situations.'

Education and awareness about protecting environment at the early stage of student learning can play a big role to save it. Bhavisha Buddhadeo, a social activist and an expert in organic farming and kitchten gardening based in Gurgaon (India), is doing just that as a mission to promote ecological wellbeing and safeguard environment. She conducts learning workshops and lectures on importance of sustainability and how to better care for the environment. Ms. Buddhadeo says, 'I have engaged children and women in plantation drives, kitchen garden activities and (a) solar energy initiative to educate them regarding the utmost importance of conservation of nature. Schools are doing environmental education and (the) best have made sustainability a school-wide, hands-on project, rather than just another topic for children to write reports on. My programs offer opportunities for experiential learning outside of the classroom, (and) enable students to make connections and apply their learning in the real world.' In her career spanning about 20 years she has taught 100000 students from across many states of India. Read on...

According to meteorologists, the recent flooding in southwestern state of Kerala in India has occured due to two-and-a-half times the normal monsoon rains. Climate scientists caution that if the global warming continues unabated more unusual weather events will happen. Roxy Mathew Koll, a climate scientist at the Indian Institute of Tropical Meteorology, says, 'It is difficult to attribute any single extreme weather event - such as the Kerala flooding - to climate change. At the same time, our recent research shows a three-fold increase in widespread extreme rains during 1950-2017, leading to large-scale flooding.' According to the study published in Nature last year that Mr. Koll co-authored, flooding caused by heavy monsoons rainfall claimed 69000 lives and left 17 million people without homes over the same period across India. Kira Vinke, a scientist at the Potsdam Institute for Climate Impact Research (Germany), says, 'These floods that we are seeing in Kerala right now are basically in line with climate projections. If we continue with current levels of emissions - which is not unlikely - we will have unmanageable risks.' Mr. Koll explains the weather patterns behind the excessive rains, 'Rapid warming in the Arabian Sea and nearby landmass causes monsoon winds to fluctuate and intensify for short spans of three-to-four days. During those periods, moisture from the Arabian Sea is dumped inland.' Elena Surovyatkina, a professor at the Russian Academy of Sciences and monsoon expert, says, 'Over the last decade, due to climate change, the overheating of landmass leads to the intensification of monsoon rainfalls in central and southern India.' According to a World Bank report titled 'South Asia's Hotspots', 'On current trends, India's average annual temperatures are set to rise 1.5 degree Celsius to 3 degree Celsius compared to that benchmark by mid-century. If no corrective measures are taken, changing rainfall patterns and rising temperatures will cost India 2.8% of its GDP and will drag down living standards of half its population by 2050.' Ms. Vinke says, 'What we will see with climate change in India is that the wet season is going to be wetter and the dry season drier. Already we are observing that the monsoon is becoming harder to predict with traditional methods.' A recent research predicted, 'If man-made carbon emissions continue unabated, some regions in northeast India could literally become unlivable by the end of the century due to a deadly combination of heat and humidity during heatwaves.'
