Kathmandu, Nepal - A recent study published in the journal Urban Climate highlights the critical role of urban forests, parks, and ponds in mitigating rising temperatures in Kathmandu. The study reveals that such green spaces could lower the city's temperatures by up to 1.6°C, underscoring the urgent need for policymakers and urban planners to prioritize sustainable solutions for urban heat mitigation.
Once a lush valley of green fields and historic ponds, Kathmandu has evolved into a concrete jungle, particularly since the 1970s. However, locals have long observed a significant temperature drop - as much as 5°C - when traveling just 10 kilometers from the city center to natural reserves like the Gokarna Forest Reserve.
The study also reflects on Kathmandu's warming trend due to rapid urbanization and deforestation, phenomena accelerated by unchecked development and global warming. The authors call for immediate action to restore greenery and revive ponds, emphasizing that integrating thoughtfully designed green spaces into the urban environment is the most sustainable way to combat rising temperatures.
“This is not just about planting trees; it’s about creating an ecosystem that complements the urban fabric,” the study suggests, urging against turning every available piece of land into real estate.
The findings serve as a wake-up call for Kathmandu and cities worldwide grappling with the impacts of urban heat islands. Prioritizing green infrastructure can be a crucial step toward creating livable, climate-resilient cities.
