  1. 1. Primary Production in African Drylands : Quantifying Supply and Demand Using Earth Observation and Socio-ecological Data

    Författare :Abdulhakim Abdi; Institutionen för naturgeografi och ekosystemvetenskap; []

    Sammanfattning : The human-environment connection in the mostly rural drylands of sub-Saharan Africa forms a complex, interlinked system that provides ecosystem services. This system is susceptible to climatic variability that impacts the supply of its products, and high population growth, which impacts the demand for these products. LÄS MER

  2. 2. Resilient Landscapes: socio-environmental dynamics in the Shashi-Limpopo Basin, southern Zimbabwe c. AD 800 to the present

    Författare :Munyaradze Manyanga; Paul Sinclair; Alinah Segobye; Uppsala universitet; []
    Nyckelord :Archaeology; Shashi-Limpopo Basin; landscapes; perceptions; floodplains; wetlands; drylands; ecology; socio-political complexity; local knowledge; climate change; seasonal variability; resilience; southern Africa; Arkeologi; arkeologi; Archaeology;

    Sammanfattning : The general perception today is that the Shashi-Limpopo Basin in southern Africa is hot and dry and not conducive to human habitation. Today there is no doubt that the Shashi-Limpopo Basin has been home to many communities throughout the pre-historical period. LÄS MER

  3. 3. Pastoralists, Mobility and Conservation : Shifting rules of access and control of grazing resources in Kenya's northern drylands

    Författare :Annemiek Pas Schrijver; Lowe Börjeson; Elizabeth E. Watson; Mats Widgren; Caroline Upton; Stockholms universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; pastoralism; livestock mobility; conservation; community conservancy; Northern Rangelands Trust; political ecology; access; institutions; governmentality; territoriality; Samburu; Laikipia; Isiolo; Kenya; geografi med kulturgeografisk inriktning; Geography with Emphasis on Human Geography;

    Sammanfattning : Pastoral mobility is seen as the most effective strategy to make use of constantly shifting resources. In northern Kenya, mobile pastoralism as a highly-valued strategy to manage grazing areas and exploit resource variability is becoming more complex. LÄS MER

  4. 4. Rural Livelihood Options for "a better and more sustainable future". Local perspectives from Myanmar and Morocco

    Författare :Laura Kmoch; Chalmers University of Technology; []
    Nyckelord :SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SOCIAL SCIENCES; SOCIAL SCIENCES; Rural Livelihoods; Cluster Analysis; Technology Adoption; Swidden Farming; Agroforestry; Climate Adaptation; Remittances; Local Agroecological Knowledge;

    Sammanfattning : In 2015, state leaders adopted the 2030 Agenda for Sustainable Development, to address global inequalities and respond to heightened concern about challenges, arising from contemporary global change. This thesis contributes to addressing these challenges, by extending the knowledge base that rural development stakeholders can draw on to co-construct viable livelihood options for vulnerable rural people.

  5. 5. The importance of tree cover for water resources in semiarid West Africa

    Författare :Aida Bargues Tobella; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; LANTBRUKSVETENSKAPER; NATURAL SCIENCES; AGRICULTURAL SCIENCES;

    Sammanfattning : The current paradigm in forest hydrology implies that an increase in tree cover always leads to reduced water yields as a result of increased interception and transpiration (ET) losses. This trade-off theory, in which more trees mean less water, has led to concerns that the establishment of trees in drylands may jeopardize scarce water resources. LÄS MER
