  1. 1. Water Realities and Development Trajectories : Global and Local Agricultural Production Dynamics

    Författare :Mats Lannerstad; Jan Lundqvist; Malin Falkenmark; David Molden; Paul Appasamy; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Agriculture development; food production; per capita food supply; consumptive water use; evaporation; transpiration; hydro-climatic variability; blue water resource; green water resource; irrigation; river depletion; river basin closure; adaptive water management; vegetal and animal foods; Jordbruksutveckling; matproduktion; per capita mattillgång; konsumerande vattenanvändning; evaporation; transpiration; hydroklimatisk variabilitet; blåvattenresurs; grönvattenresurs; bevattning; uttorkning av vattendrag; överintecknade avrinningsområden; anpassad vattenhantering; vegetarisk och animalisk föda.; Water in nature and society; Vatten i natur och samhälle;

    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

  3. 2. Green-Blue Water Potential: : Building water resilience to attain the SDGs on food and poverty in Africa

    Författare :Maganizo Kruger Nyasulu; Ingo Fetzer; Stefan Liersch; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; agriculture; green-blue water resilience; sustainable development goals; climate change; land use change; vetenskap om hållbar utveckling; Sustainability Science;

    Sammanfattning : Attaining the Sustainable Development Goals (SDGs) of eradicating hunger and securing sustainable food for all by 2030, constitutes a major global challenge, particularly in sub-Saharan Africa (SSA). Here, malnourishment, poverty, and population growth are among the highest in the world, and some regions are constantly subject to extreme water variability and scarcity. LÄS MER

  4. 3. Hydrological and sediment yield modelling in Lake Tana Basin, Blue Nile Ethiopia

    Författare :Shimelis Gebriye Setegn; Bijan Dargahi; Anders Wörman; C. Green Rossi; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SWAT; Lake Tana; Blue Nile; hydrological modelling; watershed modelling; MCE; SUFI-2; GLUE; ParaSol; streamflows; sediment yield; erosion; water balance; model calibration; Hydrology; Hydrologi;

    Sammanfattning : Land and water resources degradation are the major problems on the Ethiopian highlands. Poor land use practices and improper management systems have played a significant role in causing high soil erosion rates, sediment transport and loss of agricultural nutrients. So far limited meas-ures have been taken to combat the problems. LÄS MER

  5. 4. A Triply Green Revolution : Building water resilience for SDGs on food and poverty for Africa

    Författare :Maganizo Kruger Nyasulu; Ingo Fetzer; Harry Fischer; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Sustainable Development Goals SDGs; Africa; water resilience; green-blue water; agriculture; climate change; land-use change; planetary boundaries; vetenskap om hållbar utveckling; Sustainability Science;

    Sammanfattning : Sub-Saharan Africa is confronted with the urgent challenge of ensuring food security in the face of changing demographics, climate change and water vulnerability, which can lead to potential crop failure. Despite the high advocacy for technological solutions, such as irrigation, rainfed agricultural systems, which account for more than 90% of the region's food production, often remain overlooked.

  7. 5. Blue-green stormwater systems for citywide flood mitigation : Monitoring, conceptualization, modeling, and evaluation

    Författare :Salar Haghighatafshar; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; blue-green measures; drainage system; flooding; flood mitigation; hydrodynamic modeling; rainfall-runoff; stormwater;

    Sammanfattning : Considering the growth in urbanization, leading to an increase in impervious surfaces, and the changing climate, enhancing the intensity and frequency of rainfall events, existing urban drainage networks—separate or combined sewer systems—are presumed to face substantially elevated hydraulic loads, causing pluvial floods in urban areas. There are several ways to address these challenges. LÄS MER
