Evidence re Boserup's Theory Several types of evidence bearing on Boserup's theory However, in most cases we lack sufficient controls ("all else" not equal); accordingly, it may be misleading to compare yields and costs for systems in 2 different places at same time, since soil may vary, history is different, etc. Evidence on correlation between fallow period, population density, and land productivity [see Table 3 ]: 1. Palerm (1957) compared 3 Mexican peasant communities: swiddeners use 1.5 hectares/year/family, but need 12 hectares total over swidden cycle; short fallow option has lower yields (need 2.5 ha/yr/family) but total over fallow cycle is only 6.5 ha; irrigated land supports permanent crops with high yields, only need 0.86 ha/family 2. Comparisons of 17 rice growing societies in Asia by Hanks (1972) showed a direct relationship btwn intensification and population density, as predicted by Boserup's theory: swiddeners had 31 people/mi. 2
