Short description of the intervention
The Wuqing District of Tianjin is a rapidly developing suburban district, northwest of the city core, containing 4 larger 5 smaller rivers, 5 water reservoirs, Wetland area that partially protected by the DaHuangPu Nature Reserve, the Jinbei Forest Park, several public parks, greenery near buildings, green roofs and vegetation along roads. A spike in population growth going from 130.000 in 2000 to 1.2 million in 2018 brought the need for wide urban development where the district focused on implementing blue and green infrastructures (1). "The urbanized area of the district is reported to meet the requirements of the national ‘Garden City’ standard with over 36% green coverage, currently aiming to achieve 45% on the long run, and was selected as a pilot national ecological demonstration area for green urban development in 2014. Since 2014, over 500 million EUR was invested into blue and green infrastructure projects (1 p26). The three flagship projects evaluated here are 1) the South Lake (Nanhu) Area that combines business, recreational, residential, and ecological development around in a waterside area, 2) the North Canal Suburban Park which is a recreational, entertainment and wetland area on 2.53 km2 where over 72.000 trees were planted in recent years, 3) and the 400 meter wide, multi-functional green corridor running along the Cuiheng Road (1).
