Landscape architecture and design research is becoming increasingly popular due to rapid urbanization and its impacts on the urban and periurban environment. The constant mitigation and sprawl of urban areas is an imperative and key point for knowing which natural and man-made landscape innovations or patterns are the most suitable and sustainable for urban architecture and design. Such knowledge is crucial to achieving sustainable urbanization while maintaining and improving urban and periurban areas as well as providing a healthy environment for urban residents. Thus, innovative research that is supported by computational approaches, field studies, and spatial analysis to expand knowledge on sustainable urbanization is in high demand. In this Special Issue, we recruited researchers to share their state-of-the-art work on landscape architecture and design combined with sustainable solutions and other research fields such as urban blocks, urban public places, and architectural and design amenities related to urban and periurban environmental engineering for better coping with the urbanization phenomenon. Manuscripts within this Special Issue address sustainable urban design and landscape architecture; the design and management of green spaces; the planning and maintenance of periurban areas; and the expansion of urban areas and their impact on the urban-rural context.
