Earthwatch India has conducted research across three cities in India to address knowledge gaps in the management of urban lakes, wetlands and green spaces. The research informs how these ecosystems can increase the climate-resilience of urban areas, whilst continuing to provide benefits to people and wildlife long into the future. In Mumbai, Earthwatch is working with the Indian Institute of Technology Bombay to explore the feasibility of nature-based solutions to support the ecological upgrade of Powai and Banganga lakes. The results are being used to support a sustainable business model for these important water bodies, which serve as major cultural heritage and recreational centres for Mumbai’s population.
