Coastal urban ecosystems are under siege from climate change, rapid urbanisation, and environmental degradation. These escalating pressures threaten the sustainability, resilience, and well-being of communities in these regions.

India launched a landmark scheme, the PM Surya Ghar Muft Bijli Yojana, in February this year, to support the uptake of rooftop solar photovoltaics (RTPVs) in the country. Under this scheme, residential households are eligible for a subsidy of INR 30,000 per kilowatt (kW) for the first 2 kW and INR 18,000 per kW for an additional capacity of up to 3 kW. With over 1.28 crore registrations and 14.84 lakh applications, the scheme has garnered remarkable interest as highlighted in the recent union budget.
