A biodiversity park is a holistic concept to rejuvenate rivers and restore their water quality, volume, and floodplain. The park works with a three-pronged approach: restoring the degraded urban riverscapes, bioremediating of wastewater, and using floodplain to clean and store floodwater. Transforming urban river floodplains into biodiversity parks thus offers many benefits. Biodiversity parks can help clean rivers and riverbanks, provide habitat for urban biodiversity, help recharge groundwater.
