What is Landscape Architecture and Its role in Sustainable Development ?

1.0 Introduction
Landscape architects plan the most harmonious relationships between the land and the objects on it by proper combination of open space and planting. They may work on parks, gardens, housing projects, school campuses, golf courses, or airports. They begin a project by reviewing the needs and desires of the client. They study the site, mapping such features as the slope of the land, existing structures and the type of soil. They check local building codes and availability of utilities make drawings, which outline the work in detail, and draw up lists of materials to be used. They then invite bids from construction companies and landscape nursery companies. With the awarding of the contracts, their work may be finished, or they may stay on to supervise the work as their client representative , all these are included into their varies scope of work. In planning a site, landscape architects first consider the nature and purpose of the project and the funds available. They analyze the natural elements of the site, such as the climate, soil, slope of the land, drainage, and vegetation; observe where sunlight falls on the site at different times of the day and examine the site from various angles; and assess the effect of existing buildings, roads, walkways, and utilities on the project. They prepare a preliminary design. To account for the needs of the client as well as the conditions at the site, they frequently make changes before a final design is approved. They also take into account any local, State, or Federal regulations such as those protecting wetlands or historic resources. Computer-aided design (CAD) has become an essential tool for most landscape architects in preparing designs. Many landscape architects also use video simulation to help clients envision the proposed ideas and plans. For larger scale site planning, landscape architects also use geographic information systems technology, a computer mapping system.
