The paper describes the current framework which places barriers between the disciplines of environmental designers, underlining the extent of fragmentation and the need for a co-ordinated approach.
Design at the small scale is examined in its relationship to the total process. The effect of unco-ordinated decisions taken in related but separate planning disciplines is discussed and the consequences illustrated.
The impact of micro-scale design is examined with reference inter alia to the co-ordination of decision-making processes; attitudes to conservation, piecemeal growth and change; the notion of acceptable design criteria; user participation and response; and local group involvement. Aspects of the impact at the architectural scale will be illustrated.

The concept of 'The perception of the quality of life' is discussed and analysed. The measurement of the various components is illustrated and the use for national planning of such measurements is demonstrated. This is achieved through the presentation of some relevant findings of research done on the perception of the quality of life during rapid industrialization.
Die konseptualisasie van 'Die warneming van die kwaliteit van lewe' word bespreek en ontleed. Die meting van verskeie komponente word geïllustreer en die gebruik daarvan vir nasionale beplanning aangedui. Daarvoor word 'n aantal toepaslike empiriese bevindinge ivm die waarneming van die kwaliteit van lewe gedurende vinnige industrialisasie voorgedra.

Conditions for the formation of extensive floodplains are extremely limited in South Africa, for they require that a river should regularly break the confines of its normal channel to flood a substantial adjacent area which includes a number of suitable depressions to retain water over the dry season. These requirements are usually only met where a river carrying significant run-off attains grade on a flat plain. The coastal plain of northern Zululand is the only such area in the high rainfall zone of the Republic and, because of its unusual south-north course, the Pongolo River has formed a floodplain of some 10 000 ha along the eastern foot of the Lebombo Mountains. This floodplain comprises a low-lying area, incorporating a series of shallow pans, separated from the main river channel by low levees.

What can we learn from the ecological disturbances which have been caused by man in river systems? The first is that the damages or the effects of such disturbances may only become evident or serious after 10, 20 or even 30 years. The second is that secondary effects which could hardly have been foreseen sometimes play a major role in the damages that do occur.

This paper, the product of an interdisciplinary team effort, seeks to find an acceptable procedure for ensuring that proper consideration is given to the environmental consequences of the construction works necessary for progress.
It examines and commends the EPPIC approach of a voluntary assumption of responsibility by the professional planner - it being accepted that there is no substitute for good planning - but concludes that the support of carefully structured legislation is essential. The characteristics of such legislation are thoroughly examined in the paper.
A practical procedure which should be acceptable to the public is proposed. This is, briefly, to make public disclosure of the environmental impacts of significant projects mandatory in a prescribed manner, the role of the courts being solely to ensure that the proposed procedures are properly followed.

The issues involved can, I believe, be narrowed down to two basic ones, ie the aims of an EIR and the way in which we wish to implement those aims.
As far as the aims are concerned, the bare minimum is that a full disclosure of the potential environmental impact of a proposed action which may detrimentally affect the environment should be required.
