  2. 6. Dry spell mitigation to upgrade semi-arid rainfed agriculture : Water harvesting and soil nutrient management for smallholder maize cultivation in Machakos, Kenya

    Author : Jennie Barron; Carl Folke; Theib Oweis; Stockholms universitet; []
    Keywords : ;

    Abstract : Improvements in on-farm water and soil fertility management through water harvesting may prove key to up-grade smallholder farming systems in dry sub-humid and semi-arid sub-Sahara Africa (SSA). The currently experienced yield levels are usually less than 1 t ha-1, i.e. READ MORE

  4. 7. Traps and transformations : Exploring the potential of water system innovations in dryland sub-Saharan Africa

    Author : Elin Enfors; Line Gordon; Christian Valentin; Stockholms universitet; []
    Keywords : smallholder farming; water system innovations; agricultural droughts; multi-functional landscapes; development trajectories; uncertainty; NATURAL SCIENCES; NATURVETENSKAP; naturresurshushållning; Natural Resources Management;

    Abstract : In semi-arid and dry sub-humid sub-Saharan Africa (SSA), high poverty levels and a heavy reliance on small-scale rainfed agriculture make rural livelihoods difficult. Upgrading current farming systems, in a way that safeguards productivity beyond field-scale, is urgent. READ MORE

  5. 8. Compost and fertilizer - alternatives or complementary? : management feasibility and long-term effects on soil fertility in an Ethiopian village

    Author : Workneh Bedada Chala; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Decline in soil fertility due to nutrient depletion is a concern for low-input crop production in the highlands of Ethiopia. Fertilizer addition is insufficient due to infrastructural and socioeconomic constraints. READ MORE

  6. 9. Decentralised energy systems based on biomass : a life cycle perspective on climate impact and energy balance

    Author : Marie Kimming; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Replacing fossil fuels with renewable energy sources is recognised as an important measure to mitigate climate change. Residual biomass from agriculture and forestry and short-rotation coppice grown on unused land can be converted to heat, power and fuel without directly compromising production of edible crops.

  7. 10. Integrating legumes in mixed crop-livestock systems in east Africa: Farmers' perceptions, ecosystem services and support for decision making

    Author : Tarirai Muoni; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Challenges faced by smallholder farmers in east Africa include limited access to inputs, small farm sizes, and erratic rainfall patterns. Legume intensification and species diversification have been recommended for improving food and nutritional security, controlling soil erosion, improving soil fertility, supplying income and providing fuel.
