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

    Author : Abdulhakim Abdi; Institutionen för naturgeografi och ekosystemvetenskap; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; SAMHÄLLSVETENSKAP; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; SOCIAL SCIENCES; Net Primary Production NPP ; Africa; Drylands; Coupled Human and Natural Systems; Human-Environment Relations; Food; Fuel; Feed; Earth Observation; Remote Sensing; Biomass; Carbon; Supply and Demand;

    Abstract : 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. READ MORE

  6. 4. Meeting-places of Transformation : Urban Identity, Spatial Representations and Local Politics in St Petersburg, Russia

    Author : Thomas Borén; Bo Lenntorp; Thomas Lundén; Jussi Jauhiainen; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Time-space; lifeworld; Hägerstrand; Habermas; Lotman; participant observation; post-Soviet transformation; time-geography; cultural geography; cultural semiotics; urban studies; everyday life; Soviet cartography; local self-government; Ligovo; Uritsk; Krasnosel skii raion.; Other earth sciences; Övrig geovetenskap;

    Abstract : This study develops a model for understanding spatial change and the construction of space as a meeting-place, and then employs it in order to show an otherwise little-known picture of (sub-)urban Russia and its transformation from Soviet times to today. The model is based on time-geographic ideas of time-space as a limited resource in which forces of various kinds struggle for access and form space in interaction with each other. READ MORE

  7. 5. Optics for Earth Observation Instruments

    Author : Arvid Hammar; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; off-axis; free-form mirrors; measurements; stray light; spline horns; THz; reflector optics; satellites; scientific instruments; diamond turning; tolerancing; telescopes;

    Abstract : The optical system is an essential part of every remote sensing instrument used for detecting electromagnetic waves. Careful design, fabrication and characterization is therefore crucial, especially for satellite-borne missions where the possibility of post-launch repairs is highly limited. READ MORE
