  2. 6. Fluid-induced alteration of metasedimentary rocks in the Scottish Highlands

    Author : Alexander Lewerentz; Alasdair Skelton; Patrick Crill; Charlotte Möller; Jay Ague; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; metamorphic fluids; metamorphic fluid flow; fluid-rock interaction; metamorphic fluid fluxes; Geology; geologi;

    Abstract : Fluids, mainly H2O and CO2, are released from H- and C-bearing phases during prograde metamorphism. Because of the buoyancy of these fluids, they rise within the crust towards the surface of the Earth. Metamorphic fluids take advantage of permeable horizons, shear zones, fold hinges, fractures, and are channelled into high-flux zones. READ MORE

  4. 7. Addressing water scarcity in the Bolivian Altiplano for sustainable water management

    Author : Claudia Canedo Rosso; Avdelningen för Teknisk vattenresurslära; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Hydrology; Climatology; climate modes; Drought; Water balance; ENSO; Soil moisture; crop yield; Remote sensing; Bolivian highlands; arid and semiarid regions; Climate anomaly;

    Abstract : Water scarcity is a consequence of complex interactions between water access and water use. In fact, the time period over which precipitation deficit accumulates is a determing factor for the occurrence of drought. Drought induces crop production losses and far-reaching societal effects. In the South American Altiplano, drought is a major hazard. READ MORE

    Abstract : This study analyses the history of a large hydroelectric scheme – the Great Ruaha power project in Tanzania. The objective is to establish why and how this specific scheme came about, and as part of this to identify the key actors involved in the decision-making process, including the ideological contexts within which they acted.

  6. 9. Rainfall variability, soils and land use changes in the Ethiopian highlands

    Author : Staffan Rosell; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; rainfall change; soil productivity; tef; land-use changes; South Wollo; water harvesting;

    Abstract : Most farmers in the Ethiopian highlands are dependent on rain-fed agriculture. The indigenous cereal tef is the most important crop for the farmers in the highlands. The central highland is an environmentally fragile area and a marginal area of Ethiopia with a recurring problem for the farmers to sustain an adequate agricultural production. READ MORE
