  2. 21. Hydro-climatic changes in irrigated world regions

    Author : Shilpa Muliyil Asokan; Georgia Destouni; Howard Wheater; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Climate change; hydro-climatic change; evapotranspiration; irrigation; water demand; water balance; land-use; water-use; hydrological catchment; Aral Sea; India; Mahanadi River Basin; Physical Geography; naturgeografi;

    Abstract : Understanding of hydro-climatic changes in the world’s river basins is required to ensure future food security. Different regional basins experience different levels of hydro-climatic change depending on the endorheic or exorheic nature of a hydrological basin, along with the climatic conditions and human land and water-use practices, for instance for irrigation.

  4. 22. Land use dynamics in the face of population increase. A study in the districts of Gatsibo and Nyagatare, Eastern Province, Rwanda

    Author : Theophile NIYONZIMA; Göteborgs universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; land use dynamics; land cover changes; population increase; cropping; livestock; political ecology; Rwanda;

    Abstract : This thesis is about land use dynamics in areas undergoing population increase. The study was undertaken to clarify how the increasing population interacted with their physical environment through farming in Eastern Province, Rwanda. READ MORE

  5. 23. Land-use and land-cover dynamics and rural livelihood perspectives, in the semi-arid areas of Central Rift Valley of Ethiopia

    Author : Efrem Garedew; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Global environmental changes in climate, land-use and bio-diversity are increasingly on top of scientific and political agenda. The impacts of climate change are manifested on all dimensions of food security: availability, accessibility, utilization and stability. READ MORE

    Abstract : As global urbanization progresses, cities worldwide are growing in size, which leads to many economic, environmental, and management challenges. Recent advancements in spatial data analysis and algorithmic geography have also led to the development of various urban model-based planning support systems (PSS) for urban planning. READ MORE

  7. 25. Anthropogenic impact on predator guilds and ecosystem processes : Apex predator extinctions, land use and climate change

    Author : Marianne Pasanen Mortensen; Bodil Elmhagen; Francisco Palomares; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Mesopredators; apex predators; top-down; bottom-up; interspecific killing; red fox; Eurasian lynx; grey wolf; wolverine; productivity; winter severity; cropland; zoologisk ekologi; Animal Ecology;

    Abstract : Humans affect ecosystems by changing species compositions, landscape and climate. This thesis aims to increase our understanding of anthropogenic effects on mesopredator abundance due to changes in apex predator status, landscape and climate. READ MORE
