Presented by Professor Andrew Learmonth, this programme fits within the Regional Section of the course. Using Professor Learmonth's own work and experience in the study of development in the State ...of Mysore in South Central India, it attempts to delimit the usefulness of traditional geographic work. The second part of the programme takes the statistical technique of linear programming, and by explaining its basic components suggests a use for this method in determining the actual possibilities for development given a region's resources The explanation of LP is done graphically and the limitations of the simplified approach are explained.

Footage description: Professor Learmonth introduces the programme and outlines its purpose. Map showing degrees of development within South India. Learmonth explains the map and the methodology by which it was compiled, namely principal component analysis. Learmonth turns to a more detailed examination of the Maidan, an area within Mysore State. He describes it in terms of resources, industry, products etc. A series of illustrative photographs is screened behind Learmonth. Learmonth now goes on to consider two examples of the planning recommendations that arose from the survey of the Maidan. A rainfall graph showing the double peaks is shown in connection with the first recommendation. The second recommendation dealing with the use of cultivatable waste land is illustrated with an appropriate map. Learmonth explains why the geographer rather than the agronomist or agricultural climatologist was better able to indicate and isolate these recommendations. He continues with a further brief description of other recommendations made. Limitations to the survey are also pointed out. Learmonth now leaves the Mysore Survey to discuss in detail a technique which permits the geographer to calculate the best combination of industries to fit the particular combination of resources of a particular region. Learmonth describes the technique of linear programming and its use for the geographer. Illustrative graphs are shown. After the introduction, Learmonth goes on to demonstrate the technique on a hypothetical area, the resources of which are defined. The figures are converted to graph form and the hypothetical example worked through. After plotting the four limitation lines, these are now combined into a composite line representing the actual limitation to maximum growth. Learmonth explains in considerable detail the implications of the graph. The graph is now read to show maximum growth and maximum increased income for the hypothetical region and also the best possible combination of industries to achieve them. Learmonth then goes on to stress that this is a demonstration of principles only and that actual application requires greater subtlety. Credits.
