    Keywords : TEKNIK OCH TEKNOLOGIER; LANTBRUKSVETENSKAPER; SAMHÄLLSVETENSKAP; ENGINEERING AND TECHNOLOGY; AGRICULTURAL SCIENCES; SOCIAL SCIENCES; Forest transitions; Land cover; Carbon footprints; Agriculture; Forestry; Carbon emissions; Land use; International trade; Deforestation;

    Abstract : Deforestation is a major source of human-caused greenhouse gas emissions and the largest threat to terrestrial biodiversity. Most forest loss is due to the expansion of agricultural land use increasingly driven by international demand for food, fuel and fibre. READ MORE

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

    Author : Eugene Ejike Ezebilo; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : 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. READ MORE

  5. 5. Stand dynamics in undisturbed and selectively logged tropical rainforest over 18 years : effect of logging intensity and climate extremes

    Author : Daniel Lussetti; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Rainforests in Southeast Asia are enormously important, both ecologically and socio-economically, but their sustainability is severely threatened by various forms of disturbance that perturb the dynamics of forests here and elsewhere. To help efforts to counter such threats, this thesis focuses on two of the most important forms of disturbance that currently affect tropical rainforests: logging and extreme climatic events.
