- ‘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.

- 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.

- 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.
