‘Country’s first sponge park’ to save rainwater, cut urban flooding risk in Karachi

A novel water-saving initiative in Gulberg Town, Karachi has been inaugurated as the country's first sponge park. This innovative urban green space, located in Jamali Park, is designed to manage rainwater effectively, reducing the risk of urban flooding during monsoon events. The park, spanning one acre, features a range of eco-friendly elements such as rain gardens, bioswales, and permeable pathways.

These features are engineered to temporarily store runoff in shallow planted areas, allowing it to replenish groundwater after retention. Permeable pathways enable water to seep into the soil below, further aiding groundwater recharge. In addition to these sponge elements, the park also boasts native trees, a biodiversity zone, and a pollinator zone to support urban wildlife.

The incorporation of a community learning area further enriches the park, offering visitors an opportunity for experiential learning and a deeper connection with nature. The WWF-P, working in collaboration with the Gulberg Town Municipal Corporation and GSK, has introduced this unique design to demonstrate how local governments can translate climate commitments into tangible outcomes.

Experts have hailed the park as a practical example of how urban green spaces can effectively support biodiversity and contribute to global biodiversity goals. By turning climate commitments into real-world action, the Jamali sponge park sets a precedent for other municipalities to emulate in their efforts to enhance urban water management, biodiversity, and overall microclimate.
