1. 1. Advancing the Implementation of Protective Measures for Drinking Water Sources in Sweden

   Författare :Nadine Gärtner; Chalmers tekniska högskola; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; water protection; mitigation measures; spatial planning; groundwater; surface water; drinking water; risk assessment;

   Sammanfattning : The world’s drinking water sources are under growing pressure due to human activities, including infrastructure projects, agriculture, climate change, and the ever-increasing need for freshwater. Although there is a strong call to protect our source waters instead of increasing treatment efficiency at the drinking water treatment plant, the extent of protection measures is often hotly debated.

3. 2. Urban Water Security – Local Conditions and Regional Context : A case study of attitudes and water use behaviour in Windhoek, Namibia

   Författare :Therése Sjömander Magnusson; Jan Olof Lundqvist; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; water supply; urban; water management; water demand management WDM ; vattenförsörjning; Namibia; Water in nature and society; Vatten i natur och samhälle;

   Sammanfattning : The world is becoming urbanised. Between 1995 and 2025, it is estimated that the cities and towns of the developing world will have absorbed another two billion people. A majority of these people will be poor and settle down in the unregulated areas. LÄS MER

4. 3. Sustainable and Safe Use of Non-conventional Waters -Reclaimed Water and Desalinated Water

   Författare :Shuang Liu; Avdelningen för Teknisk vattenresurslära; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Water reuse; Desalination; Strategy; Water security; Guidelines; Policy; Microbial risk assessment;

   Sammanfattning : Fresh water scarcity, pollution and an uneven distribution have caused an increasingly serious global water crisis. One of the most widely adopted response strategies is the exploitation and use of non-conventional water sources. LÄS MER

5. 4. Evaluation of Modern Irrigation Techniques with Brackish Water

   Författare :Tarek Selim Aboulila; Avdelningen för Teknisk vattenresurslära; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Soil water; Soil Salinity; Drip irrigation; HYDRUS-2D 3D; El-Salam Canal; Egypt.;

   Sammanfattning : Modern irrigation techniques are becoming increasingly important in water-scarce countries especially in arid and semiarid regions. Higher crop production and better water use efficiency are usually achieved by drip irrigation as compared to other irrigation methods. LÄS MER

7. 5. Small Sanitation Systems – Treatment Efficiency, Sustainability and Implementation

   Författare :Brenda Vidal; Annelie Hedström; Inga Herrmann; Günther Langergraber; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sustainable sanitation; sand filter; phosphorus filter; package plant; cold climate; treatment process; system analysis; sustainability indicators; decentralization; centralization; historical development; on-site; resource recovery; source separation; source-separating systems; blackwater; urine; greywater; hållbarthetsanalys; små avlopp system; enskilda avlopp; markbädd; minireningsverk; kallt klimat; systemanalys; fosforfälla; fosforfilter; indikator; urin sortering; svartvatten; toalettvatten; gråvatten; BDT; VA-teknik; Urban Water Engineering;

   Sammanfattning : Current socio-technical wastewater system paradigms are being challenged by emerging global issues such as climate change, environmental degradation and scarcity of resources. Thus, exploration of innovative new urban water management solutions is required that enable closure of resource loops. LÄS MER
