City greening often fails to address the issue of urban heat islands — areas that are several degrees warmer than their surroundings.

India's preparedness to face a warming world hinges on some cool solutions.

Over the past few months, a team of researchers from Sustainable Futures Collaborative, an independent research organisation, assessed nine Indian cities' readiness to deal with the extreme heat of a +1.5° Celsius world. They found that only in Ludhiana, Punjab, had the authorities aligned tree plantation drives with the city's heat map — a representation of temperatures or radiation over an area. Everywhere else, this particular intent was missing while choosing sites for greening.

"In Ludhiana, the city administration had partnered with educational institutes to draw out the city's heat map. The planting sites were chosen accordingly, and they are also monitoring the cooling as the trees grow," says Tamanna Dalal, one of the researchers.
