Walk through any city, and you'll encounter Nature-based solutions (NbS) everywhere: urban parks providing respite from hot streets, wetlands filtering stormwater, and trees along busy roads reducing air pollution, among others. This green infrastructure, however, is often viewed through a narrow lens—as mere providers of shade, picturesque spaces, or recreational spots.  This limited perspective has harmful consequences. When development pressures mount or budgets tighten, these natural assets become expendable and are often removed without proper analysis of their multidimensional benefits. This is where quantifying the benefits of NbS becomes essential. By measuring and monetising the value these solutions provide, we…

Urban Heat Islands (UHI) are areas within cities that experience significantly higher temperatures than their rural counterparts due to human activities, concretisation, and lack of vegetation. Bengaluru, the fifth most populous metropolis (Census of India, 2011) and one of the rapidly growing cities in India, is no exception. In the last two decades, the city has seen a rapid rise in built-up area from 37.4% to 93.3%. The pressure of urbanisation has not only affected the natural and ecological resources but is also impacting the city’s livability because of rising temperature levels. Unlike sudden disaster events like landslides or floods,…

As Bengaluru struggles with an ongoing water crisis, it reports a shortage of about 500 million litres of water every day. The significant water problem in the city is frequently blamed on insufficient rainfall, unregulated groundwater exploitation, and environmental negligence. However, it is essential to investigate water contamination, notably from sewage and industrial effluents, as a major cause of the water crisis. The focus then moves to Shivpura Lake in the Peenya Industrial Area.  Although a key industrial area, Peenya is neglected, as evidenced by its poor infrastructure and pollution issues. Shivpura Lake, in particular, is contaminated by the surrounding…
