Abstract:In the world of earlier scientists a frontier was an exciting concept, term and line. It is not quite so now. Presently frontiers are zones that are partially settled and with limited transportation. They vary in size but in total area and in location they present significant potentials for population growth absorption. From about 1900 to 1940 frontier development was international and intercontinental in scope; now it is primarily national or regional in scale. Currently about as much of the total area in world frontiers is in stability as in growth and there are considerable areas of decline. The present trend is toward more stability while urbanization is dominating; until these two really change only major military causes will produce notable variations in frontier use while individual national political policies will result in local geographical pulses of minor advances and retreats. Yet, there is much potential area for new food production and settling, the world is still largely in a growth syndrome, and there are alternatives that also should be considered.
