Originally an earthen ditch on the Guandu Plain, adjacent to the nature park and irrigated rice fields, this canal often suffered from collapse on the side near the rice fields, causing farmland loss and water blockages. The other side, bordering Guandu Nature Park, was prone to overgrowth and subsequent blockages. To address these problems and preserve the native ecosystem, the project employed natural materials to enhance the original irrigation and drainage functions while creating habitats for wildlife and wildlife-friendly corridors. This approach balanced agricultural needs with ecological preservation, achieving sustainable development goals.
