In Bengaluru, more than two-thirds of plastic waste comprise household products like personal care and food packaging, dominated by milk packaging (KMF, Dodla, Heritage, Milk Mist etc.), which contributes a big chunk of such waste. The use of plastic packaging material has increased over the years particularly with the growth of e-com companies, with Amazon leading the list. Among product companies, the leading brands which use a lot of plastic material to package their products include Unilever, Coca Cola, Reckitt Benckiser, ITC and Britannia. These are the findings from a plastic brand audit exercise, conducted in September 2021. Hasiru Dala…

The 6th report by the Intergovernmental Panel on Climate Change (IPCC), titled, 'IPCC 6th Assessment Report Working Group II (AR6)' was released globally on February 28th. Analysing environments of 195 member countries, the report has, this year, revealed that the global climate crisis is possibly much worse than we had thought. It states clearly that around 40% of the world's population is "highly vulnerable" to climate change. The IPCC report refers to Mumbai multiple times and says the city has new challenges ahead as it grapples with coastal degradation and temperature changes. Climate impact on the urban poor Mumbai is…

For better or worse, we are married to plastics, and plastics have permeated into our very being. What was once invisible, is suddenly all round us, in the form of waste and pollution. Simple everyday plastic products such as water bottles, plastic bags, toys, throw-away cutlery, fast fashion, food packaging, personal care products, all seemingly harmless, are all causing severe environmental problems, in the form of plastic pollution. From clogged storm water drains to beach litter, from dead rivers to air and soil pollution.  Surgeries performed on animals to remove plastic from the bellies make it to the news regularly. …

In recent years, Bengaluru’s usually year-round pleasant weather has seen unusual scorching summers and intense rainfall and flooding during monsoons. What’s causing this, and is there anything we can do about it? Responding to these questions in an interview with Citizen Matters is Dr J Srinivasan, Distinguished Scientist at the Divecha Centre for Climate Change, IISc. He has been associated with IISc since 1982 and had helped establish the Divecha Centre at the IISc in 2009. He was chairman of the Centre from 2009 to 2016.  A Ph D from Stanford University, Prof Srinivasan has been a lead author of…

Every year, rains in Mumbai claim lives and leave behind destruction to infrastructure and the city’s economy. Excessive flooding in the city is only increasing. The 2021 report by the Intergovernmental Panel on Climate Change (IPCC) warned us about rising sea levels in Mumbai in the coming years, and, towards the end of the century, the city is set to see a 4.6 degree celsius rise in mean temperatures.  In January 2022, the Centre for Study of Science, Technology and Policy (CSTEP) released a report on emerging trends of climate change in Western India. The report provides trends for western…

The existing state of urban biodiversity, environment and natural heritage in Bengaluru is a matter of urgent concern. The impacts of ecological degradation is already felt in the city - for example, monsoons are often accompanied by the grim news of many areas getting flooded. Many of these vulnerable sites are found in large layouts and real estate projects that are built in valley zones and adjacent to lakes/rajakaluves (primary stormwater drains). A favoured market for the real estate sector, Bengaluru has witnessed an increase in built-up area that has replaced its green cover and wildlife habitats. Built-up area has…

On January 22nd, a healthy and flourishing peepal tree, approximately 100 years old, was chopped at Azad Road in Vile Parle East. Junior Tree Officer of K East ward, Mr. Pradip Jadhav, arrived at the spot at 9:30 am** with his team to cut the tree. At the sight of this, I asked the officials about permission they had been granted for the operation, and learnt that the notice was given four years ago in December 2017. The permission to cut, after objections, was given in November 2018. Because of it’s outdatedness, in a constrained manner, I requested the officers…

Sprawling, manicured lawns in neighbourhood parks, golf clubs, hospitals, and the airport may seem like oases of greenery. But the fact that they are green deserts -- negatively impacting soil fertility and displacing food crops such as finger millet, pulses, paddy -- is often overlooked.  These are some of the findings in a 2018 study by Dr Seema Purushothaman, Sheetal Patil, Raghvendra Vanjari, A R Shwetha and Dhanya Bhaskar, from Azim Premji University, titled  ‘The Other side of Development – Green Carpet or Green Desert?’. The study was conducted in the rural peripheries of North Bengaluru. About why the study focused…

Over the past  few years, especially after the December 2015 floods, we have seen varying figures  on the number of lakes being restored in the Chennai Metropolitan Area. Greater Chennai Corporation, through the Chennai Smart Cities Limited has a goal of restoring  210 lakes, working with NGOs and other civic organisations who are also working on lake restoration independently. Much of these restoration efforts are volunteer-driven and typically involve clean ups, erecting fences and creating spaces for birds. Some restoration efforts also involve removal of encroachments, desilting, and reviving connecting channels.  As of June 2021, around 180 water bodies under…

Last year, Chennai experienced intense rains and flooding yet again, bringing the city to a standstill for days. Excess flooding in the city has been associated with poor planning and urban development projects over the years. Rapid urbanisation in erstwhile agricultural lands and wetlands, and increased concretisation have altered the natural flow of rainwater. This is what has often led to debilitating floods.  Existing infrastructure to manage flooding has been criticised by city dwellers and environmentalists for incomplete construction, lack of topographic study before implementation, and lack of linking drains to natural channels.  A growing concern is the fact that…
