  2. 1. Integrated Agriculture and Aquaculture Systems (IAA) for Enhanced Food Production and Income Diversification in Tanzania

    Author : Deogratias Mulokozi; Håkan Berg; Ian Bryceson; Stockholms universitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Smallholder farmers; Oreochromis niloticus; Amaranthus hybridus; food production; household income diversification; water use efficiency; farm net income; Physical Geography; naturgeografi;

    Abstract : Aquaculture production in Tanzania has increased in recent years, responding to an increased demand for fish, partly because of an increasing population and declining catches of wild fish. However, the current aquaculture production is still low, dominated by small scale farming systems, that are struggling with a number of challenges such as lack of improved fish breeds, feeds, technical skills and low adoption rates.

  6. 4. Wind Farm Configuration and Energy Efficiency Studies - Series DC versus AC Layouts

    Author : Stefan Lundberg; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : In this thesis, the design and control of a wind farm utilizing series-connected wind turbines with a DC output has been evaluated. The advantage is that a suitable DC voltage level, appropriate for transmission of the generated power directly, without using a large centralized DC/DC converter, can be obtained. READ MORE

  7. 5. Smallholder farm management and priorities : balancing productivity, livelihood, climate adaptation and ecosystem services

    Author : Ylva Nyberg; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Smallholders in sub-Saharan Africa are highly vulnerable to climate change, but also have good potential for improving production. This thesis examined how Kenyan smallholders manage their farming systems to adapt to rainfall variability and improve productivity, while also maintaining sustainable delivery of multiple ecosystem services.
