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…

India’s urban population went up from 17.9% in 1960 to 34.9% in 2020. Bengaluru’s population in the same time period increased more than 10 times. The city’s urbanisation has led to Bengaluru's Land Surface Temperature (LST) increasing from 33.08℃ in 1992 to 41℃ in 2017 -- a whopping 24% increase! Researchers from the Indian Institute of Technology, Kharagpur have analysed Bengaluru’s urban expansion and how it affected surface temperatures. The study titled Analyzing and Predicting Urban Expansion and Its Effects on Surface Temperature for Two Indian Megacities: Bengaluru and Chennai also predicts the city’s urban area in 2025. Key findings…

Last October, around 700 houses in Bengaluru were damaged after heavy rains and flooding. The saga continues this year - 70 houses were flooded on June 4, and more on July 5. For hundreds of low-income families in Bengaluru, heavy rainfall in the last few years have meant intense damage or even losing their home. Flooding can also lead to the inflow of sewage into slums, which further increases the risk of water-borne and vector-borne diseases. Flooded roads and underpasses don't just choke traffic for hours, but they also increase the likelihood of accidents. Flooding has also been leading to…

The COVID pandemic has exposed our hollow development strategies aimed at achieving the United Nations' sustainable development goals (SDGs), to which India is a signatory. This hasn’t just brought to the fore the need for revisiting our strategy to move forward for a better and equitable world harmonious with nature. At the same time, it has also thrown light on how the present processes will not help in achieving any landmark advancement in attaining close proximity to the sustainable development goals. Instead, what we are witnessing is a catastrophe of unprecedented proportions. To elucidate further, here are a few critical areas that require immediate intervention if we…

On February 10th, 2021, Citizen Matters organised an online round-table discussion on ‘Climate Crisis and Environmental Sustainability: Lessons for Tier 2 cities’. The discussion was a logical extension of a series published on Citizen Matters, and supported by Climate Trends, that looked at climate change and environmental sustainability in cities like Bhubaneshwar, Chandigarh, Shimla, Rishikesh and Varanasi. The intense session saw a deep exploration of the various sustainability challenges before India's Tier 2 cities and towns, and the systemic gaps underlying such manifestations.

A discussion with a difference Over the latter half of 2020, Citizen Matters commissioned a series of articles, supported by Climate Trends, to look at climate change and environmental sustainability in Tier 2 towns like Bhubaneshwar, Chandigarh, Shimla, Rishikesh and Varanasi. Why Tier 2, one may ask. Because if and when there is a spotlight on issues of sustainability or the urban climate crisis, it is usually the metros that are at the centre of it. Air Pollution is invariably associated with Delhi/NCR, discussions around water crisis are more often than not Chennai-centric, while waste and mobility issues are mostly…

There can be no dispute over the fact that the frequency, intensity and spread (new cities getting affected) of urban floods is increasing in India. The reasons are mostly known: increasing and mostly unplanned urbanisation, rural-urban migration, encroachments of water bodies, concretization of flood plains and other lands, decreasing capacity to hold, store, recharge and drain the rainwater, increasing rainfall intensities with changing climate, wrong operation of big dams and deteriorating governance. The damages are going up, also because our forecasts are far from reliable, accurate, location-specific or with sufficient lead time. Because of our incapacity to learn lessons. Disaster…

During the virtual celebration of World Environment Day on June 5th this year, Prakash Javadekar, India’s minister for environment, forests and climate change, launched the Nagar Van project. The scheme aims to create urban forest cover in 200 cities across the country in the next five years. Oddly enough, in 2016 Javadekar launched the exact same scheme at a commemorative function at the Sanjay Gandhi National Park in Borivali, Mumbai. None of the experts The Third Pole’s correspondent spoke to were aware of any progress on the scheme. Nor is any government data available on what goals were achieved on planting “200 city forests” between 2016…

This article is part of our special series Environmental Sustainability & Climate Change in Tier II cities supported by Climate Trends. Chandigarh: The Beautiful City, located in the foothills of Shivalik range, was originally a cluster of 58 villages. When the site was chosen to build a modern capital for the then state of Punjab in 1948, it resulted in relocation of 21,000 people, mainly farmers cultivating crops such as wheat, corn, and maize. The city lies in the Indo-Gangetic plains, between two seasonal hill torrents – the Sukhna and Patiali rivers. Presumably, back then it was a much cooler…

This article is part of our special series Environmental Sustainability & Climate Change in Tier II cities supported by Climate Trends. In May 2018, 51-year old Shail Bala Sharma, an Assistant Town Planner (ATP) was shot dead at Kasauli –a popular hill station and cantonment in Solan district, known for its quaint colonial buildings and landmarks. She was out to enforce a Supreme Court order to demolish half a dozen illegal constructions in the town, mainly hotels, lodges and guest houses. Hotelier Vijay Singh, whose hotel was slated for demolition, allegedly opened fire on her and the accompanying town and country…
