1. The relationship between climate, disease and coffee yield: optimizing management for smallholder farmers
Sammanfattning : Climate change and diseases are threatening global crop production. Agroforestry systems, which are characterized by complex multispecies interactions, are considered to provide nature-based solutions for climate change mitigation and pest and disease regulation. LÄS MER
2. Engendered promises, gendered challenges : Changing patterns of labor, control and benefits among smallholder households growing NERICA in Uganda
Sammanfattning : NERICA is a new group of high-yielding and stress-tolerant upland rice varieties, developed by the Africa Rice Center to address the continent-wide rice challenge, poverty and food insecurity. Recognizing that African women farmers do not always benefit from the introduction of productivity-enhancing technology and higher-value crops, the aim of my thesis is to understand processes leading to NERICA-related wellbeing outcomes among differently comprised grower households in Hoima District, Uganda, by examining inter- and intrahousehold gender dynamics.

3. Changing the risk at the margin : Smallholder farming and public policy in developing countries
Sammanfattning : This thesis consists of a summary and four self-contained papers. Paper [I] examines whether the implementation of a social safety net programme in Ethiopia has affected the value, risk and composition of farmers‟ crop portfolios. LÄS MER
4. 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.

5. Uncertain Futures : Adaptive capacities to climate variability and change in the Lake Victoria Basin
Sammanfattning : The Lake Victoria basin (LVB) in East Africa can be considered a climate change hotspot because of its large rural population dependent on rain-fed farming. Drawing on extensive fieldwork (2007-2011) in rural communities along the shores of Lake Victoria in Kenya and Tanzania, I explore adaptive capacities to climate variability and change and discuss how they interrelate in situ.
