    Sammanfattning : Water constraints for humans and nature are gaining more and more public attention as a critical environmental dilemma that needs to be addressed. When aquifers and rivers are running dry, the debate refers to an ongoing “world water crisis”. LÄS MER

    Sammanfattning : Wood is a natural raw material, and would hardly be considered a risk to the environment. However, the handling of wood materials on an industrial scale has been shown to have a negative impact on water bodies that run-off from industrial sites that process wood-based materials. LÄS MER

  4. 4. Water management and performance on local and global scales A comparison between two regions and their possibilities of knowledge transfer

    Detta är en avhandling från Stockholm : Department of Land and Water Resources Engineering, Royal Institute of Technology

    Författare :Nasik Najar; [2010]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The problem to secure safe water supply, good sanitation and a good watercourse and marine environment status has become increasingly complex and at the same time more and more important to meet. It has been recognized, that an integrated approach must be used to meet not only technical and scientific aspects, but the role should also be included of factors such as economics, acceptability, capacity building, and efficient management in the overall view.

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Land system sience; socio-environmental change; telecoupling; scale; co-production of knowledge; participatory art project; network science; blue and green water; Africa; Land grabbing; Remote sensing;

    Sammanfattning : A major challenge of our time is to sustainably produce food and other goods for a growing global population, without putting additional pressures on land and water resources and local people’s quality of life. Large-scale agriculture has brought many benefits to humanity in terms of food production but has also caused multiple sustainability challenges, including land and water degradation, deforestation, and biodiversity loss in areas of production.
