The essence of spatial planning is to create order to development within human settlements which in turn promotes safety, economy and beauty. Certain controls /constraints are necessary if people have to enjoy their freedoms / rights (esp. for the weaker members or land uses). 1.1 Definitions
Planning:
* Basic human activity * Deciding what to do in advance of doing it * Concerned with providing the right site, at the right time, and in the right place, for the right people (Ratcliffe, 1981) * A discipline based on the premise of order, convenience, economy and beauty. * Keeble (1965) described it as the art and science of ordering the use of land and the siting of buildings and communication routes so as to secure the maximum practicable degree of economy, convenience and beauty.
Urban Planning, in this regard, has been defined as a conscious direction of human effort aimed at attaining a rational, efficient and cost effective land use in urban areas. The same definition can also be applied to the planning of both rural and regional areas which are the other domains of planning. In both urban and rural areas, for instance, the acknowledgement that land is a constant resource in space and time implies the need for deliberate planning and development of such areas in order to enhance their utilization, based on the existing technological capacity (Mwangi, 2002).
Development: The making of any material change in the use or density of any buildings or land or the subdivision of any land (Physical Plannning Act Cap 286 of 1996)
Sustainable development: “Development that meets the needs of current generations without compromising the ability of future generations to meet their own needs” (WCED, 1987, p. 45).
Development control: * A planning activity that tries to cut down on possible infringement on freedom of others in human settlements * A process by which legal permission is
