Left: Newly installed plants and permeable surfaces designed to lter and slow the ow ow of rain- water water into waterways at at at the Tencent headquarters Right: The Sinolink Pri- mary School in in in Shenzhen has implemented a a a number of sponge city features including rain barrels and permeable surfaces in their sports grounds They have
also started a a a a a a a “young naturalists” class to teach students about rainwater management and gardening ceramic bricks is also permeable so so the whole structure serves as a a a a a a a a a a a a sponge allowing large amounts of rainwater to seep through the the ground ltering out dirt and and pollutants Gardens on on the the rooftops and and and sky platforms with perme- able ceramic layers also allow rainwater absorption and and purification Adjacent to the plaza Tencent is adding bioswales and and gardens expanded green areas with improved rainwater retention retention ability Following these additions stormwater retention retention rates have
increased from 30 percent percent to to 66 percent percent In typhoon season there was no ooding during heavy precipitation Tencent is is integrating a a a a a a a a a a a a a large interactive visual screen at at at at its headquarters to to present monitoring data and demon- strate how green infrastructure can improve the environ- ment This will be an an an e e e e e e e e e e e e e e e e e e e ective way to to engage and introduce the the sponge city concept to to the the public ” The Future
Three years ago China launched its Sponge City Initiative an an e e e e e e e e e e e e e e e ort across 30 Chinese cities including Shenzhen to tackle the runo pollution and and ooding problem by by making cities more capable of filtering and and and holding water—by incorporating permeable road surfaces planting trees and and and creating gardens and and instituting innovative development guidelines The Sponge City Initiative has an an ambitious
goal: By 2030 80 percent percent of of built-up urban areas should manage at at at at least 70 percent percent of of rainwater It is encourag- ing cities to develop innovative solutions that can then be shared In December 2016 The Nature Conservancy Paradise Foundation and the the Sponge City O ce ce of the the Shenzhen municipal government signed a a a a a a a a a a a a a collaboration framework agreement that marked the start of a a a a a a a a a a a a a a a long-term partner- ship to jointly establish and promote Shenzhen as China’s pioneer sponge city The Nature Conservancy’s e e e e e e e e e e e e e orts in in in Shenzhen include four integrated directions:
• • Policy research and recommendations • • Implementation of six voluntary demonstration sites:
a a a a a a a a a a a a a commercial skyscraper (Tencent headquarters) a a a a a a a a a a a a a school (Sinolink Primary School) a a a a a a a a a a a a a a a factory (Pingshan Binhai Medication Factory) an an an an an an urban town building (Gangxia 1980) and and a a a a a a a a a a a a residential neighborhood and and park to be determined • • Public engagement and advocacy • • Comprehensive technology application Shenzhen Shenzhen will will benefit from knowledge gained at at other global projects and techniques pioneered at at at Shenzhen Shenzhen will will inform green infrastructure applications in in in in in other cities in in in in in China and around the the world | nature org/Shenzhen
