We show in Table 1. 2. iv the projected acreage in cropland for the period under review. Actual limits in the supply of good agricultural land result in projections of a very modest size.

We conclude that, given the characteristics of the high population density in relation to land resources, there will be considerable pressure in the West Indies for industrialisa- tion and urbanisation and emigration on the one hand, and for increasing yields on the other. Population pressure may tend to depress yields by the cultivation of marginal and sub-marginal land resources; but we believe that the latter will be of importance in the future period with which we are concerned. The factors which will probably be of most import- ance in increasing yields are better breeds of plants and livestock and reduction of disease. Economic factors are also important, but in the West Indies one of the main cost prob- lems, low labour productivity, is difficult to remedy. It is also probably unfortunate but true that so long as labour is plentiful and land is scarce, capital will tend to be spent rather on improving productivity per acre than per man. As a result of our consideration of acreages and yield factors we project the total sup- plies of commodities. These are summarized for main commodities in Table 1.2. v. It will be noted that the rates of growth of production are not high except possibly for cocoa; the growth rate for this product is approximately comparable to that experienced by bananas and sugar in the period 1948-60. The products for which the least expansion is predicted are root crops, sea island cotton, corn and pulses. Reconciliation of demand and supply and import demand The reconciliation of demand and supply figures produced data on import demand for those products that are partly locally produced and partly imported. Import demand in- formation for commodities that are wholly imported are derived from the demand table. Import demand is shown in summary form in Table 1.2. vi.
