    Abstract [en]

    Is it possible to survive on a deserted farm: Manors, tenants and farming systems during the Middle Ages in the Lägerbo area, Östergötland. 

    This study approaches the late medieval farm desertion from a landscape perspective. It focuses on the area of a former medieval estate in southern Östergötland, Sweden. Based on a retrogressive analysis of cadastral maps and historical records the medieval settlement is reconstructed. In this process three formerly unknown deserted farms were identified, with abandoned field systems and building remains.  The volume provides the archaeological documentation of field systems and settlements at these sites. These data provide the background for investigating the shifting social and ecological circumstances that once made it possible for tenant families to survive on these farms. During the height of the manorial system the small farms were specialised units in a redistributive system. In the late 14th century the estate and all tenant farms were donated to the convents of Vadstena and Vreta.  Rents were no longer paid in labour but in butter.  In the fifteenth century several farms were abandoned and turned into meadows under the surviving farms. The new tenurial relations prevented the recolonization of the farms. The study is the result of an interdisciplinary project involving medieval archaeology, historical geography, palynology and medieval history.

    Green economy, Scandinavian investments and agricultural modernization in Tanzania2018In: The Journal of Peasant Studies, ISSN 0306-6150, E-ISSN 1743-9361, Vol. 45, no 4, p. 825-852Article in journal (Refereed)
    Abstract [en]

    ‘Green economy’ is a broad concept open to different interpretations, definitions and practices ranging from the greening of current neoliberal economies to radical transformations of these economies. In Africa, one emerging and powerful idea in the implementation of the green economy seems to be to use a green agenda to further strengthen development as modernization through capital-intensive land investments. This has again reinvigorated old debates about large-scale versus smallholder agriculture. Influential actors justify large-scale ‘green’ investments by the urgency for economic development as well as to offset carbon emissions and other environmental impacts. In this contribution, we discuss the case of the Southern Agricultural Growth Corridor of Tanzania (SAGCOT) to give examples of how the green economy may materialize in Africa. SAGCOT is presented by the Tanzanian government as well as investors and donors as a leading African example of an ‘investment blueprint’ and as a laboratory to test green growth combining profitable farming with the safeguard of ecosystem services. In particular, we discuss three Scandinavian investments within SAGCOT, their social implications and their discursive representations through the public debates that these investments have generated in Scandinavia.

    The vulnerable continent (PLATINA): Historical perspectives on Africa´s climate, environment and societies2009In: Meeting global challenges in research cooperation: Proceedings of a conference and workshop in Uppsala, May 27-29, 2008 / [ed] Ingrid Karlsson, Kristina Röing de Nowina, Uppsala: Uppsala University, 2009, p. 585-596Conference paper (Refereed)
    Abstract [en]

    Our research, based on studies of different climate archives from Tanzania, Mozambique and South Africa, contributes information on changes in climate and vegetation over the past 24000 years. This time perspective, reaching beyond the information available from instrumental records is needed for a better understanding of regional global climate dynamics and issues surrounding environmental change, throughout Africa, and is a prerequisite for increasing climate forecasting capabilities for the region. We argue that African people have vast experience from living in a variable climate and research on past interactions between climate and societies demonstrate the significance of lessons learnt for present situations. Our findings, underline the complex interactions between climate/environment and societies that may lead to different developments in time and space. Considering the so called vulnerable continent, extended investigations of how African communities cope with and adapt to climatically driven changes is needed to increase the capability to realise the potential as well as the limitations, of modern African communities to adapt to future climate change.

    Labour and landscapes: The political economy of landesque capital in 19th century Tanganyika.2007In: Geografiska Annaler Ser B, Human Geography, Vol. 89B, no 3, p. 233-248Article in journal (Refereed)
    Abstract [en]

    In a long-term and global perspective irrigated and terraced landscapes, landesque capital, have often been assumed to be closely associated with hierarchical political systems. However, research is accumulating that shows how kinship-based societies (including small chiefdoms) have also been responsible for constructing landesque capital without population pressure. We examine the political economy of landesque capital through the intersections of decentralized politics and regional economies. A crucial question guiding our research is why some kinship based societies chose to invest their labour in landesque capital while others did not. Our analysis is based on a detailed examination of four relatively densely populated communities in late precolonial and early colonial Tanzania. By analysing labour processes as contingent and separate from political types of generalized economic systems over time we can identify the causal factors that direct labour and thus landscape formation as a process. The general conclusion of our investigation is that landesque investments occurred in cases where agriculture was the main source of long-term wealth flow irrespective of whether or not hierarchical political systems were present. However, while this factor may be a necessary condition it is not a sufficient cause. In the cases we examined the configurations of world-systems connections and local social and economic circumstances combined to either produce investments in landesque capital or to pursue short-term strategies of extraction.

    The spatial and temporal change of cropland in the Scandinavian Peninsula during 1875–19992013In: Regional Environmental Change, ISSN 1436-3798, E-ISSN 1436-378X, Vol. 13, no 6, p. 1325-1336Article in journal (Refereed)
    Abstract [en]

    Land use and land cover change (LUCC) has emerged as an important issue of global change with significant influences on the geochemical cycle and regional climate change. Understanding the historical changes of land use and analyzing the environmental effects of LUCC make such reconstructions important. Based on historical statistics, this article reconstructs cropland area at the municipality level (härad/kommun) in the Scandinavian Peninsula during 1875–1999. The total acreage of cropland increased 36.84 % during 1875–1930, kept stable during 1930–1950, and decreased 14.25 % during 1950–1999. The croplands of Sweden and Norway both increased before 1950 and changed in different ways during 1950–1999 when the cropland decreased by 19.79 % in Sweden but increased by 9.63 % in Norway. The counties in the south Scandinavian Peninsula owned most of the cropland, with a cropland proportion of over 20 %, and experienced relatively obvious cropland changes. Growth centers with a rate of increase of over 5 % during 1875–1910 were found in Skåne, Stockholm, the Uppsala counties in Sweden, and the area around Oslo county in Norway. The general cropland distribution showed almost no change during this period, which mainly reflects the suitability of the natural conditions for agriculture. Multi-social factors co-impacted land use activities and induced temporal and spatial variations of the cropland. These factors included food supply, world trade, wars, agriculture policies, the economic and political environment, urbanization, and national differences. Compared with the widely used global land use dataset Historical Database of the Global Environment (HYDE), this study shows different cropland change curves before 1950. This article is a case study showing that the hindcasting model of the HYDE dataset has difficulty estimating multi-determined cropland change in the Scandinavian Peninsula, and the empirical study contributes to the improvement of the accuracy of historical land use data at the regional level.

    Drivers and trajectories of land cover change in East Africa: Human and environmental interactions from 6000 years ago to present2018In: Earth-Science Reviews, ISSN 0012-8252, E-ISSN 1872-6828, Vol. 178, p. 322-378Article in journal (Refereed)
    Abstract [en]

    East African landscapes today are the result of the cumulative effects of climate and land-use change over millennial timescales. In this review, we compile archaeological and palaeoenvironmental data from East Africa to document land-cover change, and environmental, subsistence and land-use transitions, over the past 6000 years. Throughout East Africa there have been a series of relatively rapid and high-magnitude environmental shifts characterised by changing hydrological budgets during the mid- to late Holocene. For example, pronounced environmental shifts that manifested as a marked change in the rainfall amount or seasonality and subsequent hydrological budget throughout East Africa occurred around 4000, 800 and 300 radiocarbon years before present (yr BP). The past 6000 years have also seen numerous shifts in human interactions with East African ecologies. From the mid-Holocene, land use has both diversified and increased exponentially, this has been associated with the arrival of new subsistence systems, crops, migrants and technologies, all giving rise to a sequence of significant phases of land-cover change. The first large-scale human influences began to occur around 4000 yr BP, associated with the introduction of domesticated livestock and the expansion of pastoral communities. The first widespread and intensive forest clearances were associated with the arrival of iron-using early farming communities around 2500 yr BP, particularly in productive and easily-cleared mid-altitudinal areas. Extensive and pervasive land-cover change has been associated with population growth, immigration and movement of people. The expansion of trading routes between the interior and the coast, starting around 1300 years ago and intensifying in the eighteenth and nineteenth centuries CE, was one such process. These caravan routes possibly acted as conduits for spreading New World crops such as maize (Zea mays), tobacco (Nicotiana spp.) and tomatoes (Solanum lycopersicum), although the processes and timings of their introductions remains poorly documented. The introduction of southeast Asian domesticates, especially banana (Musa spp.), rice (Oryza spp.), taro (Colocasia esculenta), and chicken (Gallus gallus), via transoceanic biological transfers around and across the Indian Ocean, from at least around 1300 yr BP, and potentially significantly earlier, also had profound social and ecological consequences across parts of the region.

    Through an interdisciplinary synthesis of information and metadatasets, we explore the different drivers and directions of changes in land-cover, and the associated environmental histories and interactions with various cultures, technologies, and subsistence strategies through time and across space in East Africa. This review suggests topics for targeted future research that focus on areas and/or time periods where our understanding of the interactions between people, the environment and land-cover change are most contentious and/or poorly resolved. The review also offers a perspective on how knowledge of regional land-use change can be used to inform and provide perspectives on contemporary issues such as climate and ecosystem change models, conservation strategies, and the achievement of nature-based solutions for development purposes.

    A simulation model of farming systems and land use in Sweden during the early Iron Age, c. 500 B.C. – A.D. 5501979In: Journal of Historical Geography, ISSN 0305-7488, E-ISSN 1095-8614, Vol. 5, no 1, p. 21-32Article in journal (Refereed)
    Abstract [en]

    In investigating an area with deserted fields and boundaries in the province of Östergotland, Eastern Middle Sweden, pollen analysis has been used as a tool in describing the ecological base of different phases in the development of the cultural landscape. The characteristics of the early Iron Age expansion have thus been proven to be the simultaneous expansion of cattle breeding and arable farming. This indicates an integrated system, with intensely tilled fields, knowledge of manuring and, therefore, need of a vast fence system to gather the cattle and make efficient use of the manure.

    Assuming a social organization of families with a size of eight to ten individuals, the amount of land required to feed each unit has been calculated. Three hectares of arable land, 30 ha of meadow land and 30 ha of pasture is suggested as a possible combination to support a family. Using a desk computer, units with these proportions of land have been randomly located in an area of 2 × 2 km2 taking soil differences into account. Agrarian units can be located several times at random and the resulting land-use patterns studied. The simulated results often very well describe the actual land-use pattern during the early Iron Age as indicated by deserted fields, boundaries and dwelling sites.

    Besieged Palaeonegritics or Innovative Farmers: Historical Political Ecology ofIntensive and Terraced Agriculture in West Africa and Sudan2010In: African Studies, ISSN 0002-0184, E-ISSN 1469-2872, Vol. 69, no 2, p. 323-343Article in journal (Refereed)
    Abstract [en]

    This article provides an overview of the historical occurrences of terracing, manuring and other features of intensive agriculture in West Africa and Sudan. The aim is to shed more general light on the political, economic and social contexts of precolonial intensive farming in sub-Saharan Africa. The article uses the vantage point of recent debates on driving forces behind terracing and irrigation in East Africa. It argues that despite being regularly cited as fact in the literature on terraced agriculture on West Africa, no clear historical evidence is available to show that slave raiding was indeed the determining factor behind the first settlement of these hills and the terracing. The farming systems of the late precolonial period must definitely be seen as an outcome of the political economy of the slave trade period. But the idea that the intensification is the outcome of the retreat of decentralised societies into hills and mountains is challenged by the fact that intensification also occurred on the plains and in areas dominated by stratified social organisation and predatory states. It seems as if the labour mobilisation required for intensive agriculture was achieved at both ends of this social continuum. Conflicts and defensive strategies, as well as cooperation in the forms of intermarriage, trade, etc, formed part of a long-term process of different groups relating to one another, intensifying their agriculture and developing a geographical division of labour.

    Bysamfällighet och tegskifte i Bohuslän 1300-17501997Book (Other academic)
    Abstract [en]

    This is a study in the historical geography of a medieval Norwegian province, based on field evidence, Danish and Norwegian, medieval and early modern sources, and 17th-to-18th century, Swedish cadastral maps. In previous literature, eastern Norway, including Bohuslän, is described as having been characterised by single farms with fields held in severalty. This study shows, however, that concentrated settlements, as well as subdivided fields existed in Bohuslän already in medieval times. The settlement development in Bohuslän, and possibly also in the rest of eastern Norway, must thus be seen as part of general European process, rather than a specifically Norwegian development, isolated from the rest of northern Europe. The specific forms that open fields took can, however be explained by some region-specific factors, among which the rules of inheritance were the most important.

    Climate and causation in the Swedish Iron Age: Learning from the present to understand the past2013In: Geografisk tidsskrift, ISSN 0016-7223, E-ISSN 1903-2471, Vol. 112, no 2, p. 126-134Article in journal (Refereed)
    Abstract [en]

    The paper reassesses the role of climate as a factor shaping changes in settlement and landscape in the Swedish Iron Age (500 BC to AD 1050). Two reasons motivate this re-evaluation. First, high-resolution data based on climate proxies from the natural sciences are now increasingly available. Second, the climate-related social sciences have yielded conceptual and theoretical developments regarding vulnerability and adaptability in the present and recent past, creating new ways to analyse the effects of climatic versus societal factors on societies in the more distant past. Recent research in this field is evaluated and the explicitly climate deterministic standpoint of many recent natural science texts is criticized. Learning from recent approaches to climate change in the social sciences is crucial for understanding society–climate relationships in the past. The paper concludes that we are not yet in a position to fully evaluate the role of the new evidence of abrupt climate change in 850 BC, at the beginning of the Iron Age. Regarding the crisis in the mid first millennium AD, however, new climate data indicate that a dust veil in AD 536–537 might have aggravated the economic and societal crisis known from previous research.

    Furrows in Africa — canals in the Americas?2014In: Azania, ISSN 0067-270X, E-ISSN 1945-5534, Vol. 49, no 4, p. 524-529Article in journal (Refereed)
    Abstract [en]

    This brief comment argues that the use of the term furrow system for locally developed irrigation in Eastern Africa is misleading in an international comparative perspective. It is at odds with the terminology in irrigation engineering and also with the archaeological terminology used outside Eastern Africa. Internationally, the term canal is used for the artificial watercourses that bring water from the source to the field, while furrow irrigation refers to one specific way of applying water to the individual field.
