    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, 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 Holocene. For example, pronounced environmental shifts that manifested as a marked change in the rainfall 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, anthropogenic land use has both diversified and increased exponentially associated with the arrival of new subsistence systems, crops, migrants and technologies, 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 easy to clear 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 yr BP and intensifying in the 18th and 19th centuries, was one such process. These caravan routes possibly acted as conduits for spreading New World crops such as maize (Zea mays), tobacco and tomatoes, although the processes and timing of their introduction remains poorly documented. The introduction of SE Asian domesticates, especially banana, rice, taro, and chicken, 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, we explore the different drivers and directions of land cover change, the associated environmental history and multiple interactions with the distribution of 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 interaction between people, the environment and land cover change are most contentious and/or poorly resolved. The review also critiques how this perspective on regional land use change can be used to inform and provide perspective for contemporary issues such as climate and ecosystem change models, conservation and the achievement of nature based solutions to development.

    ‘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.

    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.

    Earlier work on the terraced settlements of the Bokoni area (16th to 19th century, Mpumalanga province, South Africa) focussed on the homesteads, their contents, layout and chronology. This paper suggests a terminology and typology of agrarian structures in Bokoni in order to improve comparative approaches in Africa and beyond. The typology and an excavation of the terracing have made possible preliminary conclusions relevant for the further analysis of the terracing and stone-walling in Bokoni. The terracing developed incrementally, whereby cultivation, stone-clearing and terracing were intermixed processes. This is supported both by the organic content in a section of a terrace and by a phytolith analysis. The phytolith analysis furthermore indicated that maize was cultivated on the terraces, but this should be seen as a pilot study only, and presence of maize in Bokoni must be tested with other archaeobotanical methods.

    Widgren, M. 2015. Linking Nordic landscape geography and political ecology. Norsk Geografisk Tidsskrift-Norwegian Journal of Geography Vol. 00, 00-00. ISSN 0029-1951. The article analyses and compares two schools of landscape research - post-war European landscape history and Nordic landscape geography - and compares them with political ecology. Each of them developed within a specific political, environmental, and intellectual context. European landscape history developed as curiosity-driven research, but in the shadow of previous ideological misuse of settlement history. Political ecology developed in the context of the Sahel crisis and provided a radical answer to Malthusian simplifications of the desertification and land degradation. In contrast to that, Nordic landscape geography grew as an intellectual critical reaction to a European situation in which post-productivist landscape policies were on the agenda. The article also speculates on challenges ahead and suggests that the epoch when we understand European landscapes mainly from a post-productivist standpoint may be over.

    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.
