Study Highlights Nature-Based Solutions to Prevent Climate Losses
A study suggests Chennai should use nature to protect against climate change.
They want to build green roofs and use special pavements that let water soak in.
These changes could prevent flooding and save money in the long run.
The government, businesses, and neighboring cities need to work together.
It's like planting trees and building ponds to help the city stay safe from heavy rain and rising sea levels.
These changes can reduce the potential losses from climate change.
A study recommends Chennai adopt nature-based solutions (NbS) to reduce climate-related risks.
The Center for Study of Science, Technology and Policy (CSTEP) conducted the study.
Key solutions include green rooftops and permeable pavements.
Partnerships with developers and coordination with neighboring cities are suggested.
The study projects that NbS could save Chennai from substantial climate-related losses.
