LUCKNOW, June 5 -- Extreme heat is no longer just a weather event in Uttar Pradesh. It is increasingly becoming an environmental consequence of how land, water and natural resources have been managed over decades. Scientists say shrinking forests, depleted groundwater, river degradation, mining and rapid urbanisation have weakened the natural systems that once cooled the landscape, creating what they describe as a growing "heat trap". The phenomenon is most visible in Bundelkhand, where Banda recently emerged as one of the hottest places in the world. Yet experts insist the crisis is not irreversible. The same ecosystems whose decline has intensified the heat - forests, rivers, wetlands and groundwater reserves - could also provide the most effective route out of it. As temperatures soar across the state, scientists are increasingly focusing not only on how Uttar Pradesh got trapped in the heat, but also on how it can cool itself again. This summer, residents of Lucknow and several districts across UP are finding themselves trapped in what experts describe as "open-air heat chambers" - a consequence of the Urban Heat Island (UHI) effect. The starkest example emerged from Banda, which shot into global headlines on April 27 when the mercury touched a blistering 47.6degC, making it the hottest city in the world among 8,212 meteorological stations monitored that day. Barely three weeks later, on May 19, Banda sizzled at an even higher 48.2degC, this time claiming the distinction of being the hottest city in the country. Even Lucknow, despite having a green cover spread across 8.33% of its geographical area and vast urban lungs such as Janeshwar Mishra Park, Lohia Park and Kukrail, has not escaped the heat's wrath. The state government has attempted to strengthen green cover through mass plantation drives. Uttar Pradesh has planted over 200 crore saplings during the past seven years. Experts, however, say the full impact will take time as saplings mature into trees. According to the Forest Survey of India, the state's green cover stands at 9.96%, while the government aims to increase it to 15% by 2030. On May 19, while Banda dominated headlines, Agra and Jhansi recorded scorching highs of 46.5degC, while Prayagraj endured 46.4degC the following day. Asked about some UP districts recording high day and night temperatures, forest, environment and climate change minister Arun K Saxena said, "The impact of climate change is not seen in a year or two; it takes 25 to 30 years for its effects to become evident. However, the government is taking steps to counter its impact. The government is aware of the situation and is working on it." Scientists and environmental researchers say the extreme temperatures witnessed in Bundelkhand are not merely the result of global warming or a particularly harsh summer. Prof Venkatesh Dutta of Babasaheb Bhimrao Ambedkar University said, "Banda in Bundelkhand region got hot because several stressors piled up at once. Climate crisis, water scarcity, poverty, and forest loss are all feeding each other. The Bundelkhand region has rocky terrain that intensifies heat, very low humidity, and hot dry Westerlies blowing in. Also anticyclone near the Thar desert pushes hot winds toward Banda. Low vegetation and low water in the Ken and Baghain rivers add to the heat." What is unfolding in the drought-prone district is the gradual creation of a heat trap - a landscape where forests have disappeared, rivers have weakened, groundwater has retreated and exposed land absorbs and radiates heat with growing intensity. "Deforestation and mining are removing tree cover and degrading rivers. In Banda there is less shade and less water," said Prof Dutta. "Banda is traditionally known for high temperatures due to its geology, but now it is about heat stress as night temperatures have also been constantly rising. This has reduced the diurnal variation, causing immense heat stress for people," said KJ Ramesh, former director-general, Indian Meteorological Department (IMD). Additionally, global warming has increased moisture levels over the Indo-Gangetic Plains. Rising heat stress has increased power demand while limited access to cooling infrastructure in Bundelkhand adds to health risks, Ramesh said. "Lucknow itself has seen humidity levels reaching 57-69%, with the IMD warning that heat and humidity together are making the summer harder to endure. With rivers shrinking and rainfall remaining scarce, heatwave conditions are persisting," said Anjal Prakash, professor of public policy at Flame University....
