This blog post examines how scattered fields, which appeared inefficient in medieval European rural areas, could endure by interlocking with risk dispersion, communal grazing, and resource utilization structures.
The typical form of agricultural land ownership in medieval Western Europe was ‘scattered open fields’. This refers to a structure where there were no fences between one farmer’s land and another’s, allowing free movement between them, and where a single farm’s land was not concentrated in one place but divided into small plots scattered across multiple locations. The community enforced that adjacent plots cultivate the same crop, ensuring sowing and harvesting occurred nearly simultaneously. This method allowed for communal grazing of livestock on fallow fields after harvest, using their manure as fertilizer to restore soil fertility. So why were the fields deliberately scattered, rather than simply leaving them unfenced?
Since the 19th century, medieval historians have sought the reason in a communal ethos aiming for equitable plowing or equal land holdings that accounted for differences in soil fertility. However, in the 1970s, McCloskey changed the approach to the question. Like earlier historians, McCloskey agreed that scattered fields were less efficient for agricultural production than consolidated ones. So why did this seemingly inefficient form of land ownership persist for so long?
McCloskey found the inherent efficiency of scattered fields in their ‘insurance effect through risk diversification’. According to his argument, crop yields can vary significantly across plots within a relatively small area due to pests, diseases, or climate changes. Therefore, considering risk, just as one should not put all one’s eggs in one basket, farming on land scattered across multiple locations becomes an effective way to prepare for crop failures. In other words, the reduction in grain production caused by scattered fields corresponds to a kind of insurance premium paid to guard against risk.
Phenoaltea countered this argument, criticizing that since grain is a storable commodity, other methods could have been sufficiently utilized to prepare for the risk of short-term crop failures. He instead argued that the scattered field form was itself more efficient for grain production. In agriculture, it is crucial to allocate labor to the most efficiently usable locations over time. Thus, allocating labor such as working here today when it rains and working there tomorrow when the sun is out can yield higher efficiency.
Meanwhile, Dalman found the reason for the persistence of scattered fields in the practice of communal grazing. If individual farms fenced off their own plots, it would become difficult for other farms to engage in communal grazing. However, if the land was scattered into multiple fragments, the cost of fencing would increase significantly. Therefore, it is possible to interpret that scattered plots were adopted as an institutional mechanism to prevent individual farms from hindering the community’s efforts to achieve economies of scale in livestock farming through communal grazing. In other words, Dalman understood the scattered land system as a choice to resolve the ‘tragedy of the anti-commons’. This problem arises in situations where multiple individuals privately own resources that would be more efficiently used collectively, but where obtaining consent for joint use from all owners is structurally required. This concept contrasts with the ‘tragedy of the commons,’ which occurs when multiple people privately abuse a resource they jointly own.
Henry Smith also analyzed scattered open fields in relation to common grazing, but unlike Dahlmann, he viewed it as a choice to solve the ‘tragedy of the semi-commons.’ According to his perspective, resources possessing both private and public ownership characteristics face unique problems due to opportunistic behavior, with medieval European open fields being a classic example. While grain cultivation requires efficient private use of small plots, livestock grazing demands efficient communal use of large areas, leading to the same land being utilized at different scales depending on the season. Thus, open fields functioned dualistically as both private and common land depending on the season. This created an incentive to concentrate actions favorable to cultivation—such as fertilizing crops with livestock manure during communal grazing—on one’s own land, while concentrating actions detrimental to cultivation—like livestock trampling and damaging the soil—on others’ land. Smith explains that the scattered field tenure system was precisely the solution to this problem.
Thus, the scattered open field system in medieval Europe was not merely a vestige of custom, but can be understood as the complex result of various factors: risk dispersion, efficiency in labor allocation, the institutional maintenance of communal grazing, and the suppression of opportunism in semi-communal and semi-private resources. This analysis reveals more clearly the socioeconomic background that allowed the seemingly inefficient system of scattered fields to persist over the long term.
