  1. 1. The Political Economy of Deforestation of the Northwestern Colombian Amazon

    Master-uppsats, Stockholms universitet/Institutionen för biologisk grundutbildning (BIG); Stockholms universitet/Stockholm Resilience Centre

    Författare :Paula Andrea Sanchez Garcia; [2021]
    Nyckelord :Amazon; Colombia; power dynamics; political economy; hegemony;

    Sammanfattning : The Amazon has experienced rapid forest loss in the past decades due to the growing colonization, infrastructure development and commercial agriculture expansion. Understanding the underlying social, political and economic drivers of deforestation is key to curb deforestation of the Amazon basin. LÄS MER

  3. 2. Emission of methane from tree stems in the Amazon basin : A study to investigate short temporal and spatial variability of methane emission of tree stems in the Amazon basin

    Kandidat-uppsats, Linköpings universitet/Tema Miljöförändring

    Författare :Magdalena Lindgren; Ida Pehrson; [2018]
    Nyckelord :Methane; tree stems; greenhouse gas; gas exchange; carbon cycle; seasonally flooded forests; short temporal variability; spatial variability; Amazon basin;

    Sammanfattning : It is well known that methane (CH4) is emitted from soil, water and wetlands under anaerobic conditions through methanogenesis. CH4 is the final product of the anaerobic respiration of the microorganism methanogen. LÄS MER

  4. 3. Groundwater Chemistry in the Amazon Rainforest

    Master-uppsats, Linköpings universitet/Tema Miljöförändring

    Författare :Jennifer Leone; [2017]
    Nyckelord :Amazon; carbon flux; chemical analysis; groundwater; nutrients;

    Sammanfattning : Groundwater chemistry is highly variable and dependent on environmental conditions, and it is not entirely understood how all these factors contribute to groundwater chemistry. This study aims to examine some of the factors that contribute to groundwater heterogeneity in the Amazon Rainforest. LÄS MER

  5. 4. Potential risks and prospects of protections of a hydrokinetic turbine implemented in the Amazon River, Colombia : A theoretical and practical study

    Uppsats för yrkesexamina på avancerad nivå, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Amanda Ulvmyr; [2016]
    Nyckelord :Hydrokinetic energy; erosion; CFD simulations;

    Sammanfattning : Electricity has been proved to be a crucial factor to achieve an economic and social development in emergent countries and is seen as a necessity to deplete the world’s poverty. As energy resources are getting scarce, a higher implementation of renewable electricity generation, such as hydropower, is a necessity. LÄS MER

  7. 5. A pilot study on the coupling potential for a hydrokinetic turbine within the Amazon basin : - Optimization from an energy perspective

    Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Erik Nordqvist; [2016]
    Nyckelord :Hydrokinetic turbine; CFD-analysis; Coupling;

    Sammanfattning : Many people around the world still lack access to a reliable electricity grid. Supplying electricity to remote off grid areas like villages around Leticia, Colombia is often interrelated with high costs and geographical limitations. Today most of the electricity demand is met through the usage of diesel generators. LÄS MER
