The World Until Yesterday: What Can We Learn from Traditional Societies? Read Free

    We can observe how those four conditions are satisfied by the groups I’ve just mentioned as approaching the extreme of exclusive territories and defended boundaries. My New Guinea mountain friends have a significant investment in their year-round gardens, pigs, and forests, which traditionally gave them everything that they needed. Clearing forests and developing gardens are laborious for them, and are even more so for western NewGuinea’s Dani, who dig and maintain elaborate systems of ditches to irrigate and drain their gardens. The Iñupiat and Ainu occupy rich year-round territories with abundant marine resources of salt-water fish, seals, whales, and seabirds, freshwater fisheries and waterfowl, and inland areas with terrestrial mammals to hunt. Arnhem Land’s Yolngu similarly lived in dense populations made possible by the combination of productive coastal and inland resources. Owens Valley’s Shoshone Indians were hunter-gatherers living at relatively high densities in an area with ample water that let them irrigate land to increase its yields of edible wild grass seeds, and that provided storable harvests of pine nuts. Those food stores, pine groves, and irrigation systems were worth defending, and there were enough Owens Valley Shoshones to defend them. Finally, Yanomamo Indians maintain plantations of peach palm and plantain trees that produce their staple foods for many years and are also worth defending.
    In areas with especially large and dense populations, such as those of the Dani and the Sudan’s Nuer, not only are there separate groups each with its own territory, but those territorial groups are further organized into hierarchies of three or more levels. Those hierarchies remind us of the hierarchical organization of land, people, and political control familiar to us in our modern state societies, starting with individual house plots, and ranging up through cities, counties, and states to the national government. For instance, the Nuer ( Plate 7 ), numbering 200,000 people in an area of 30,000 square miles, are divided into tribes of 7,000 to 42,000 people each, each tribe divided and subdivided into primary and secondary and tertiary subtribes, down to villages of 50 to 700 people and separated by 5 to 20 miles. The smaller and hierarchically lower the unit, the fewer are the disputes about boundaries and other matters, the stronger are the pressures that relatives and friends bring to bear on disputants to settle disputes quickly and without violence, and the more limited is any fighting that does occur. For instance, the Nuer observe few restrictions in their treatment of neighboring Dinka tribes: they regularly raid the Dinka, steal Dinka livestock, kill Dinka men, and take home some Dinka women and children as captives while killing the others. But Nuer hostilities against other Nuer tribes consist only of sporadic cattle raids, killing of just a few men, and no killing or kidnapping of women and children.
Non-exclusive land use
    The opposite extreme of less or no exclusivity is approached under conditions that are the mirror image of the conditions selected for exclusivity. One such condition is sparse and small populations that make patrolling (other than casually looking for trespassers while out doing other things) impossible. For instance, a society consisting of just a single family can’t afford dedicated patrols, because it can’t have its single adult man spending all day seated at the top of a watch-tower. A second condition involves unproductive, marginal, variable environments with sparse and unpredictable resources, such that any territory one might feasibly claim would often (at some seasons or in a bad year) not contain essential resources, and one would then periodically have to seek resources in another group’s territory and vice versa. Third, it doesn’t pay to risk one’s life defending a territory containing nothing worth dying for: if one’s
