Future planning of tidal flat reclamation and landcover change in the research zone

In the coastal area of Jiangsu Province, according to current coastal reclamation and development plan of the province (2010), the distribution and management of the land for reclamation is based on the area between 2 different river esturies along the coastal line. In the map below, the future plan of tidal flat reclamation area between different esturies in 3 municipalities (Nantong, Yancheng and Lianyungang) are mapped based on the study of literature and existing document. In this project, Rudong is chosen to be the research zone for further study

Future planning of tidal flat reclamation

The distribution of the reclamation area is based on the location of esturies

Research zone (Rudong country)

Reclamation plays a vital role in providing land for urban expansion and guaranteeing the food security for the Jiangsu Province (Yu and Xu.2017). Recent land reclamation schemes will cause 44%–45% loss of the most important ecotopes on mid-range and low-range littoral zones (Muller et al.2020). Based on the data from landsat 4-8, The maps below shows the trend of different types of landcover. In summary, the right chart shows that the area of tidal flat has been declining since 2000 and the area of land reclamation has been growing since 1996.

Current landuse pattern and landuse trajetories of 3 different reclamation area

Based on previous study, there are 3 typical landuse pattern based on different suitability: 1. Not suitable for both agriculture and urban development ("Tidal flat→halophytes→cropland") , 2. Suitable for agriculture ("Tidal flat→halophytes→aquaculture pond→cropland"). 3. Suitable for urban development ("Tidal flat→halophytes→cropland→construction land" in the central par t of the province's coastal area).

Reorganization of the reclamation process for 3 types of coastal reclamation area

Strategies of reorganizing the reclamation process for area with 3 different suitability

Based on previous study, 3 new landuse solutions are proposed: 1. Not suitable for both agriculture and urban development (return farmland and restore salt marsh) , 2. Suitable for agriculture(aquaculture between terraced field for salt discharge). 3. Suitable for urban developme (buffer for canal and restore wetland). The aim is for balancing the time, ecological value and economical profit in the process of developing reclamation area.

Suitability assessment of 3 development modes in the new reclamation zone 3 development modes in the new reclamation zone and water integration strategies

In Northern Jiangsu, there are 3 types of developing modes for most of the tidal flat reclamation areas based on 3 categories of suitability, and they are 1)suitable for agriculture,2)suitable for urban development,3)not suitable for both agriculture and urban development (Chen Cheng. 2017). For the area 1, the development mode is: “halophytes→aquaculture pond→cropland”, for the area 2, the development mode is: “halophytes→ cropland”, for the area 3, the development mode is “halophytes→cropland→urban development”(Xu et al.2017). Meanwhile, the development modes is also relevant to the per GDP of coastal municipalities (He et al.2021).

Facilitating circular food production model in Gothenburg

SITE: Gothenburg, Sweden

03. URBAN(CIRCULAR) FOOD SYSTEM

TYPE OF PROJECT: Master thesis project

SUPERVISOR: Jorge Gil, Jonathan Cohen

BRIEF

Facilitating urban circular food system in

city region

Peri-urban food production

Nutrients recovery Residential building

According to the waste management plan of Gothenburg, Gothenburg are planning to reduce the food-waste production by 50% per inhabitant in 2030, while 20% more food waste should be sent to nutrition recovery or biogas or other equivalent purpose. In order to realize the goal of waste reducing and recycling. New system, service and facilities in the urban food waste recyclingsystem are required.

In this thesis I will explore how urban planing and design can support facilitaing circular economy in city by choosing the integration of foodwaste recycling system and future’s local food production planning ( ’Stadslandet” ). Scenario planning ,evaluation of keep performance indicators (KPIs) and geodesign methods will be applied in the project.

04. GREEN LINK

BRIEF

Green trail + Ecological corridor

In this project I researched the social-ecological solutions for connecting important biotopes which is cut through by highway-159 in the south part of Gothenburg. In the project I combine the design of ecological corridors, ecoduct with social benefits for people, like public open space, cycling route and urban permaculture space. Which provide different types of landscape for surrounding residents.

GREEN TRAIL | Vision of bioswale park and multifunctional ecoduct

5.Bioswale park in-between farmpark and residential area

In the bioswale based community park, the steep slope of the existing bioswale is widened and the overgrown grass along the ditch is replaced by local meadow species, so the bioswale become more visible and approachable, also the stormwater storage capacity is improved. Existing shrubs and trees along the biowale are moved in order to provide better vista for visitors walking in the park and residents living. Meanwhile, two 1m width gravel routes linked by 3 walkable stone check-dams on the stream are built for guiding people approach the viewpoints and small playground along the bioswale in nearby houses. New local shrubs are planted in the west slope for marking and provide protection for small playgrounds in the lawn.

6. Multifunctional ecoduct connecting Anggardsbergen and Balltorp

Over the highway159, a multifunctional ecoduct with 1:12 slope for both local target animals and local residents is planned for connecting anggardsbergen nature reserve and forest in Balltorp. Above the ecoduct, a 20M width green belt for linking ecological corridor on both sides of the highway is designed, soil type and morphology of the green belt on the ecoduct is referred from surrounding ecological corridor and patches. Also, Plants in the green belt are mainly local shrubs,herbs and meadows based on the study of species composition of the surrounding nature area. Shrubs,trunks and stone boulders are put on the green belt which function as a natural“screen”, dividing the 4M width trail for humans and the green area for animals. small infiltration ponds connected to ditches are created for attracting animals, also collecting water from the ecoduct through gentle slope.

07.Pilot project of Meiyuan children friendly community

Renovation of Shanghai Meiyuan community

Site: Shanghai, 2022

Situation: Preparing for construction

My role: Junior project leader, cooperated with community architect.

Meiyuan community was built in the 1980s.In 2023,Meiyuan community will be renovated and become one of the children friendly communities in Shanghai municipality. After discussion with local officers, teachers from school and local residents, a pilot site is selected and two scenarios (Co-build garden + Pick up harbor) are proposed, and now preparing for

continued discussion and construction.

Scenario1: Co-build edible garden (Community and school)

In the first scenario, Current plant bed is transformed into a co-build garden. Nowadays, the edge of the plant bed is divided into 4 waiting areas for kids from 4 classes. Based on the current plan, we divide the greenbelt into 4 small permaculture gardens with similar areas and students from each class are responsible for each area. Children can engage in the urban farming process, cooperating with teachers and the community. Bench is added to the edge of the co-build garden, offering a rest area for local residents and parents.

Scenario2: Pick-up harbor for parents

In the 2nd scenario, we transformed the green belt into a seating platform for local residents and parents. From 4 pm to 6 pm, the seating platform functions as a rest area for parents who pick up children. At other times, the pick up harbor can function as a rest area for local residents. Wood is used in the construction and local plants are planted, for adding more natural atmosphere for the community.

Visualization of general longlitude of the Bostanli basin

Section B-B

Section C-C

The Bostanli catchment has an extensive hinterland of approx. 40 km2. In the upstream area, many small natural streams come together and form wider streams that run towards the city. These streams are denaturalized in downstream urban areas, where infrastructure often crosses the canals. In addition, the culverts under the bridges are relatively small, resulting in bottlenecks for water drainage during extreme weather events.
