"The idea of the world system arises out of neo-Marxist scholarship, particularly the work of Wallerstein [1,2,3]. For Wallerstein, the present world system emerged in the sixteenth century with the discovery by Europeans of the new world. This allowed the population of the European world to expand beyond its carrying capacity through importing resources to supplement those within the existing nations. This set in train a system of dependency and exploitation that led to the colonial expansion and the system of markets and dependencies shaping the world into 'core', semi-peripheral and peripheral nations. The core nations initially dominant were the maritime and later industrial powers of Europe; Britain, the Netherlands, Spain and France. The system was initally built around trade, within which the European powers explored and obtained commodities for sale in Europe. These included spices, silks, and new foods. The dominance of the core was secured through their wealth and their military and naval capacities. With the discovery of new worlds, migration then settlement occurred, firstly, of the Americas and later of Southern Africa and Australia and New Zealand. One of the consequences of this migration was to create what some have called dominion capitalist societies . What characterised this group of countries was their dependency on land-based production. The beef ranches of Argentina and the sheep farms of Australia and New Zealand played a significant role in the chain of food production for the industrialising populations of Europe. A consequence of this particular pattern of production and its orientation to exporting has been a different pattern of urbanisation with cities being built on the coast and serving as entrepôt, transportation and service centres rather than bases for industrial production and attractors of rural domestic populations [5,6,7,8]. In New Zealand, for example, it was not until the post-second-world-war period that the indigenous population shifted from being rural to urban based. In 1945, the distribution was 74 per cent rural and 26 per cent urban. By 1971, this had reversed to 71 per cent urban and 29 per cent rural ."
