Urban and regional planners look at whether development ideas are practical by considering economic, human, political, legal, environmental and aesthetic issues, such as how a piece of land should be developed, and what effect this will have on the local community of the environment. Planners balance the public interest against private interests, to improve the quality of life for everyone and to build a sustainable future. It is a growing area which can have an impact on future land use decisions. Urban and regional planners require good technical skills about land use planning, a high level of communication skills, knowledge of design, economics and law, and demonstrate sound ethical and professional behavior.
