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

    Author : Chandrakant Singh; Ingo Fetzer; Lan Wang-Erlandsson; Ruud van der Ent; Axel Kleidon; Stockholms universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  4. 2. Felling Forests from Afar: Quantifying Deforestation Driven by Agricultural Expansion and International Trade

    Author : Florence Pendrill; Chalmers tekniska högskola; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL 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

  5. 3. The impact of forest on pest damage, pollinators and pollination services in an Ethiopian agricultural landscape

    Author : Ulrika Samnegård; Kristoffer Hylander; Peter Hambäck; Sileshi Nemomissa; Jaboury Ghazoul; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; agroforestry; Apoidea; Coffea arabica; crop pests; Ethiopia; forest cover; landscape ecology; moist afromontane forests; pollination; species composition; tropical agriculture; Plant Ecology; växtekologi;

    Abstract : The distribution of wild biodiversity in agroecosystems affect crop performance and yield in various ways. In this thesis I have studied the impact of wild biodiversity, in terms of trees and forest structures, on crop pests, pollinators and the pollination services provided in a heterogeneous landscape in southwestern Ethiopia.

  6. 4. 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

  7. 5. Secondary succession in tropical dry forests : drivers and mechanisms of forest regeneration

    Author : Geraldine Derroire; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Secondary succession is a complex process involving numerous factors acting across scales. Understanding secondary succession in tropical dry forests is important for the conservation and restoration of this highly threatened biome. READ MORE
