Erica Gies writes about the surprising ways that urban areas are dealing with water woes across the world.
The good news? Houston had already begun shifting gears, hoping to reduce the severity of future floods by reclaiming 183 miles of natural waterways that snake through the city and 4,000 acres of adjacent green space from industrial areas through a project known as the Bayou Greenways. The goal is to absorb rain where it falls, reducing the volume rushing into stormwater detention facilities, and to encourage biking and walking as “active transit” in the parks that make up the Bayou Greenways.
With these measures, Houston is beginning to embrace a worldwide trend in urban retrofitting — layering new infrastructure on top of old to help cities weather climate change. In many places, that includes reducing greenhouse gas emissions: shifting to cleaner energy, making buildings more efficient and improving public transit. For cities facing increased threats from floods and droughts, it also means adapting to a changing world by finding new ways to manage water.”
