6. Fertile grounds? : Collective strategies and the political ecology of soil management in Uganda
Sammanfattning : Proceeding from land degradation and soil fertility decline in sub-Saharan African smallholder agriculture and drawing on empirical research with smallholder farmers in Tororo district in south-eastern Uganda (2010-2012), this thesis identifies local collective strategies in response to changing livelihood conditions. In an attempt to co-produce knowledge with a transformative potential, the thesis also illustrates how action research can be employed to envision, implement and evaluate a locally anchored practice to improve soil fertility, namely the use of human urine as a crop fertilizer.

7. Between Nature and Modernity : Agroecology as an alternative development pathway: the case of Uganda
Sammanfattning : Agricultural modernization has massively increased global food supply, but at a high environmental cost. Today many are calling for an agricultural ‘paradigm shift’, including several mainstream institutions. LÄS MER
8. Large-Scale Land Acquisitions as a Driver of Socio-Environmental Change : From the Pixel to the Globe
Sammanfattning : A major challenge of our time is to sustainably produce food and other goods for a growing global population, without putting additional pressures on land and water resources and local people’s quality of life. Large-scale agriculture has brought many benefits to humanity in terms of food production but has also caused multiple sustainability challenges, including land and water degradation, deforestation, and biodiversity loss in areas of production.

9. Pathways to future cropland : Assessing uncertainties in socio-economic processes by applying a global land-use model
Sammanfattning : Global agricultural production almost tripled within the last five decades. The production increase wasbased on expanding cropland and pastures, as well as the intensification of agriculture, including increased use ofhigh yielding crop varieties, machinery, irrigation, artificial fertilisers, and pesticides.

10. Biodiversity in Agricultural Landscapes: Landscape and Scale-Dependent Effects of Organic Farming
Sammanfattning : Declines in the distribution and abundance of many farmland species during recent decades have been attributed to agricultural intensification. Agri-environment schemes are commonly used in Europe to reduce this loss of farmland biodiversity, but their effectiveness may depend on several external factors. LÄS MER
