  1. 1. The rough journey to access health care : the case of leishmaniasis in the Bolivian rainforest

    Författare :Daniel V. Eid Rodríguez; Miguel San Sebastián; Isabel Goicolea; Anna-Karin Hurtig; John Porter; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cutaneous leishmaniasis; Health-care access; risk factors; population surveillance; capture-recapture; health care seeking behavior; intralesional pentavalent antimonials; economic analysis; cost analysis; budget impact analysis; Bolivia; rainforest; Public health; folkhälsa;

    Sammanfattning : Background: Leishmaniasis is a parasitic infectious disease transmitted by vectors that cause three main clinical syndromes: cutaneous (CL), mucosal (ML), and visceral (VL). Since VL is not relevant to this thesis, only CL and ML will be further discussed. LÄS MER

  3. 2. Rooting for forest resilience : Implications of climate and land-use change on the tropical rainforests

    Författare :Chandrakant Singh; Ingo Fetzer; Lan Wang-Erlandsson; Ruud van der Ent; Axel Kleidon; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Climate change; forest dynamics; human influence; land-use change; rainforest tipping; remote sensing; resilience; root zone storage capacity; tropical forests; vetenskap om hållbar utveckling; Sustainability Science;

    Sammanfattning : Tropical rainforests in the Amazon and Congo River basins and their climate are mutually dependent. Evaporation from these forests help regulate the regional and global water cycle. Furthermore, these rainforests themselves depend on precipitation to sustain their structure and functions. LÄS MER

  4. 3. The role of the hydrological cycle in forest ecosystems : flow path, nutrient cycling and water-carbon interaction

    Författare :Yanzi Yan; MERGE: ModElling the Regional and Global Earth system; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; flow path; DOC concentration; groundwater; photosynthesis; Amazon rainforest; catchment geomorphology;

    Sammanfattning : Forest ecosystems, covering over a third of land on the Earth, play a significant role in the global hydrological cycle, and influence soil erosion and climate change. However, the distribution, movements, quality of water, and hydrological processes in forested ecosystems are not well understood yet. LÄS MER

  5. 4. Natural Resource Use Conflict: Gold mining in tropical rainforest in Ghana

    Författare :Wisdom Akpalu; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Optimal taxation; Efficiency; Externality; Dynamic analysis; Firm behaviour.;

    Sammanfattning : Extraction of gold in many tropical countries is done in rainforests that provide non-timber forest benefit flows. Our model is the first attempt at modelling this conflict in a developing country in the tropics where capital for mining is from foreign direct investment (FDI). LÄS MER

  7. 5. Nature conservation in a tropical rainforest : economics, local participation and sustainability

    Författare :Eugene Ejike Ezebilo; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : The loss of tropical forests has led to establishment of protected areas such as national parks to conserve environment. National parks often affect the livelihoods of local people, especially when they are strongly linked to natural resources. For conservation efforts in a national park to be efficient, cooperation of local people is required. LÄS MER
