Urban renewal means reconstruction practices conducted upon structures and places that can no longer adapt themselves to new developments of the urban environment. Urban renewal plays a critical role in improving the living environment for modern urban dwellers, and renovation and regeneration of public open spaces has become a key component of urban renewal. The book collects many fabulous world landscape projects and focuses on urban renewal design from three aspects: conservation of historical sites, eco-sustainability of urban environment, and artistic regeneration. In this way we hope the book can help explore new strategies for urban development driven by renovation and landscape architecture.
