A decade ago, the ‘lungs of Gurugram’ - Aravali Biodiversity Park - was a mining pit, filled with mud and ‘malba’ as it chugged towards becoming a millennium city replete with towering glass buildings and construction hubs. Today, it is a 392-acre lush green forest, home to hundreds of native plant species and birds. Made possible by an NGO, IAmGurgaon, their efforts also include restoring wastelands and degraded forests in the city, setting examples of how using green infrastructure helps mitigate climate change in urban areas.
