  1. 1. Timber as a forest-risk commodity: embodied socio-ecological impacts in the Brazilian supply chain

    Författare :Caroline Sartorato Silva Franca; Chalmers tekniska högskola; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Environmentally-extended input-output model; Land use; Supply chain traceability; Forest frontiers; Sustainable Forest Management SFM ; Forest degradation; Illegal logging;

    Sammanfattning : The continued loss and degradation of forest resources is one of the largest sustainability challenges of our time. The past decades rise in global demand for agricultural and forest commodities have created unparalleled pressure on the natural resources, leading to forest destruction and associated loss in carbon stocks, invaluable biodiversity, ecosystems services, livelihoods.

    Sammanfattning : The forestry sector is playing an important role in the transition to a bioeconomy.In the supply chain of forest raw material, logging transport is a crucial component. The forestry sector must improve transport efficiency to mitigate its impact on the environment, to reduce costs and road safety risks,and to remain competitive. LÄS MER

  4. 3. SAWING STRATEGIES FOR TROPICAL HARDWOOD SPECIES : Simulation studies based on industrial conditions of Mozambique

    Författare :Pedro Ah Shenga; Dick Sandberg; Olof Broman; Mats Nylinder; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sawing strategies; tropical hardwood species; simulation; volume yield; log grading; umbila; jambirre; Träteknik; Wood Science and Engineering;

    Sammanfattning : The harvesting of Mozambique tropical hardwood species is considerable higher than the natural regrowth in the forest and the stock is decreasing drastically. Therefore, it is important to improve the material recovery when the wood is refined (i.e., in sawing and further refinement to products such as joineries, furniture etc. LÄS MER
