  2. 2. Livestock, feed production and land use – an environmental assessment

    University dissertation from Department of Physical Geography and Ecosystem Science, Lund University

    Author : Yaw Sasu-Boakye; [2015]
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; partial equilibrium modelling; land use impacts; livestock production; soya beans; life cycle assessments; ecosystem services; protein feeds; feed substitution;

    Abstract : The use of land for agriculture contributes substantially to today’s global environmental challenges such as climate change, water and land degradation and biodiversity loss. Today, about 38% of the ice-free land surface on earth is used as agricultural land, with about 75% of agricultural land used to produce feed for livestock. READ MORE

  3. 3. Uncertainty, variability and environmental risk analysis

    Abstract : ABSTRACTThe topic of this thesis is impact assessment on biodiversity in life cycle assessment (LCA). With humans in focus, we need the earth’s resources and its biodiversity for our existence and human well-being may depend on the management of the earth’s resources. The earth, however, does not need humans to continue its existence. READ MORE

  5. 5. Land use dynamics and demographic change in southern Burkina Faso

    University dissertation from ; Southern Swedish Forest Research Centre, Swedish University of Agricultural Sciences

    Author : Issa Ouedraogo; Sveriges lantbruksuniversitet.; [2010]

    Abstract : With the increasing world’s population, coupled with the technology improvement, man has emerged as the major, most powerful and universal instrument of environmental change in the biosphere today. To understand and predict the impacts of this change in the future, long-term reconstruction of land use and cover changes at global, regional and local scales is a prerequisite. READ MORE
