The site was subject to a range of primary climate change risks including loss of habitat, shrinking wetlands, increased floods and droughts, and negative impacts due to extreme weather events. Secondary climate change vulnerabilities included changes in plant phenology, reduced soil moisture, contamination of drinking water caused by flooding and eutrophication, and public health impacts caused by extreme temperature and flooding. The project is a primary example of habitat restoration with secondary benefits including wetland restoration, ecological hydrology, stormwater management, ecological remediation, and sponge city concepts. Tertiary benefits include biodiversity enhancement, vernacular preservation, and pedestrian connectivity.

The site was subject to a range of primary climate change risks including decline in mangroves, contaminated drinking water, coastal system degradation, increased coastal erosion, and loss of habitat. Secondary climate change vulnerabilities included increased floods and droughts, and negative impacts on agricultural production, cultural heritage, and rural livelihood. The project is a primary example of wetland restoration with secondary benefits including habitat remediation, ecological remediation, and sponge city concepts. Tertiary benefits include ecological hydrology, stormwater management, agrarian urbanism, and vernacular preservation.

The city of Xi’an, now a major city with a population exceeding ten million people, was once the historic capital of many different ancient Chinese dynasties for over one thousand years. Reconciling the need for urban development with Xi’an’s history is challenging: the city must continually make accommodations as new archaeological sites are discovered amid its urban fabric. The Yannan Park site was established after the discovery of twenty-five ancient sites—dating to the Han Dynasty (206 BC–AD 220) and earlier—across a forty-one-hectare area in the middle of Xi’an. While some of this area had been protected, some had been contaminated by runoff from an adjacent concrete drainage channel.57
