Hefei 2030 presents a vision for urban expansion in Hefei, the capital of Anhui province, China. The project aims to blend modern living spaces with sustainable agricultural practices through the use of aquaponics. This method allows traditional farming lifestyles to adapt within a city environment, addressing both environmental challenges and the needs of local communities. Positioned near Chaohu Lake, the largest freshwater body in the province, the design emphasizes ecological integrity while supporting community development and economic growth.

Integration of Aquaponics

At the heart of the design is the application of aquaponics, a system that combines fish farming and vegetable cultivation. This sustainable approach utilizes water from fish tanks, which is rich in nutrients, to support plant growth. The architecture incorporates growing pipes that enable efficient production of herbs and vegetables. By integrating these agricultural practices within residential areas, food production can be enhanced while reducing waste, aligning with efforts to create a more sustainable future.

Urban Layout and Grid System

The design employs a grid system to organize residential units and communal spaces effectively. This layout serves as a guideline for creating a balanced community along the lakeshore, promoting efficient land use. Various housing types are included, such as units that provide access to nature, pottery studios, and small businesses. These arrangements encourage interactions among residents, fostering a sense of community and enhancing everyday life.

Relocation Strategy and Community Cohesion

A key element involves the relocation of existing residents, primarily rural farmers. The plan offers modern housing solutions while respecting the agricultural traditions of these individuals. By maintaining agricultural activities within the urban setting, the design helps support a smooth transition for families, allowing them to keep their cultural connections. This approach ensures that the community remains united and engaged even as it shifts to a more urbanized lifestyle.

Sustainable Water Management

Water management is a vital part of the project's environmental strategy. A filtration system has been designed to recycle and return clean water to Chaohu Lake. This procedure not only sustains the aquatic ecosystem but also improves the living conditions for urban residents. The process of circulating clean water back to the lake reflects a commitment to ecological responsibility, forming a foundational aspect of the project’s design philosophy.

The layout features a mix of residential units and communal spaces. These include gardens, recreational areas, and pottery studios that blend residential life with the surrounding natural environment. This design highlights a modern approach to living that respects agricultural traditions and promotes community well-being.
