Introduction

The image of Norse Greenland as a marginal community of subsistence farmers whose eventual failure in the fifteenth century reflected an inability, or unwillingness, to change in the face of climate change and increased environmental stress has become something of a topos (cf. Diamond 2005). Evidence of increased erosion as a result of grazing pressure after the introduction of sheep, goats and cattle is widespread in southwest Greenland (e.g. Fredskild 1992), and some details of the fortunes of individual farms have been presented from palaeoecological records (e.g. Mainland 2006; Panagiotakopulu et al. 2007).

Contrasts have been drawn between the more northerly Western Settlement (Figure 1), as a place where hunters farmed, and the Eastern Settlement, whose farmers appear more akin to those of contemporary Iceland, except for the virtual absence of fish as part of their diet or economy (cf. Berglund 1986). An econocentric view (Dugmore et al. 2007) is that Norse Greenland existed as an outpost of Iceland occupied to secure access to élite trade materials, principally walrus ivory, skins and furs, for medieval Europe, and that collapse in Greenland was a consequence of the re-orientation of supply and the development of alternative materials.

Whatever the causes of abandonment, Norse Greenlandic farmers were not passive bystanders when confronted with natural or economic difficulties. They deliberately modified their landscapes in an effort to increase hay yields for their dairy stock especially. Schweger (1998) has suggested that the geoarchaeological evidence for manuring at the site of Gården under Sandet in the Western settlement amounted to the development of a plaggen soil and there is isotope evidence for selective manuring in the Eastern Settlement (Commisso & Nelson 2007). Ingstad (1966; see Arneborg 2005 for more examples) had drawn attention to evidence for water management at the site of Garðar, the modern Igaliku (Figure 1), and location of the bishop's farm and cathedral (Figure 2) in the Eastern Settlement. New evidence from Garðar implies an integrated system of manuring and irrigation of hayfields which must have required a significant annual input of labour in order to sustain it.

Garðar

In 2005, farmers at Igaliku cut a series of drainage ditches in the pasture beside the main farm complex (Figure 3). These exposed a sequence of organic deposits, rich in artefactual material and other debris overlying a gently undulating surface of sands and silts and sealed by a fibrous peat (Figure 4). The sharp basal boundary between the artefact-rich layer and basal sands/silts probably reflects the stripping of turves for the construction of farm buildings (cf. Krogh 1967), and the beginning of organic sedimentation (dating prior to cal AD 1040-1250) indicates a major change in the depositional environment.

As well as fragments of coopered bowls (Figure 5), two notched tally sticks were recovered from the upcast from the ditches (Figure 6). One is the standard merchants' tally, familiar from Bergen (Grandell 1988), the other, with its carefully carved groups of notches, is matched by similar examples from Sandnes (Kilærsavík) in the Western Settlement (Roussell 1936) and may have functioned as a rosary (Ólafsson, pers. comm.).

Ditch section at Garðar/Igaliku showing poorly sorted grey-brown sands and silts with scattered stones (i) overlain by a dark brown humified and clay-rich peat containing abundant cultural material (a plaggen soil) (ii), and sealed by brown fibrous peat lacking in artefactual debris (iii). Calibration of AMS radiocarbon dates on Montia fontana seeds using Calib Rev 5.0 produces 2σ ranges of cal AD 1040-1250 (lower sample) and cal AD 1290-1400 (upper sample).

The palaeoecological data (insects and pollen sampled from the drainage ditch) include a natural assemblage suggesting a wet eutrophic peaty field with small pools mixed with an indoor component rich in human and animal ectoparasites (essentially a stored-hay fly and beetle fauna). It appears that waste materials from the farm, including the byres - the bishop's stalls for about 100 cattle are out of all proportion to anything else in Greenland (McGovern 1992) - were being liberally spread across the hayfield to create a plaggen soil. This, combined with the evidence for wetlands in an area which might otherwise be prone to drought, implies a management of resources similar to the English use of water meadows, although considerably earlier than any known example there (cf. Bettey 1999), and Scandinavian sources (e.g. Emanuelsson & Moller 1990) imply that examples of these systems in Norse homelands may derive from English prototypes.

Saga and Icelandic law code evidence (Havarðs saga ch. 14; Grágás K187), however, indicates the use of irrigation on hayfields during the medieval period and the tradition seems also to have been maintained in the similarly drought-prone inland area of Gudbrandsdal in central Norway (Michelson 1987). It is perhaps not without significance that Greenland's first bishop, Arnald, sent out from Lund in AD 1124, became bishop of Hamar (less than 100km south of Gudbrandsdal) upon his return to Norway in 1152.

Conclusion

The extensive re-modelling of the landscape around Garðar to utilise both midden and water supply would have required the annual articulation of considerable labour. From the dating evidence, it seems that the system was maintained until the estate was finally abandoned in the fifteenth century - the cessation of manuring (cal AD 1290-1400) is a very abrupt horizon. The power of successive bishops and their bailiffs over generations of 'independent people' (sensu Laxness 1946) is evident, and would support the hypothesis that final desertion reflects a group decision implemented by the See.

The abandonment of Norse Greenland essentially fossilised a medieval managed landscape with few parallels in Northern Europe. Whilst the reintroduction of sheep farming since the late eighteenth century has caused significant damage to the remains, the evidence for manipulation of resources by the Bishop's men adds to the site's importance and strengthens the proposal to give the region World Heritage status (>http://whc.unesco.org/en/tentativelists/1781/).
