Landscape architecture is a multi-disciplinary field, incorporating aspects of urban design, architecture, geography, ecology, civil engineering, structural engineering, horticulture, environmental psychology, industrial design, soil sciences, botany, and fine arts. It is a comprehensive discipline of land analysis, planning, design, management, preservation, and rehabilitation.

Landscape architecture can be traced to the origins of man and early agricultural development, although it did not evolve into a profession until the mid-19th Century, as society sought to meet many of the new challenges of industrialization and urban growth. With that concern came the realization that cities, in particular, had to be more functional, welcoming, and aesthetically pleasing to their inhabitants.

Today, projects that involve the work of landscape architects include: residential, parks and recreation, monuments, urban design, streetscapes and public spaces, transportation corridors and facilities, waterway restoration and reuse, gardens and arboreta, security design, hospitality and resorts, institutional, academic campuses, therapeutic gardens, historic preservation and restoration, conservation, corporate and commercial, land art and earth sculpture, interior landscapes, and more
