Urban Farm DB summary

Sponge city is a Chinese urban planning model that uses green and wetland infrastructure to absorb, purify, and store rainwater. China piloted the model in 16 districts in 2015 and a further 15 cities in 2016, with a central government mandate that 80% of urban space adopt sponge-city adaptations and recycle at least 70% of rainfall by 2030. However, 19 of the 30 pilot cities have still experienced flooding since implementation, indicating implementation challenges.
