1. 1. Water supply management in an urban utility : A prototype decision support framework

   Författare :Frank Kizito; Roger Thunvik; Kalanithy Vairavamoorthy; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Decision support systems; Geographic information systems; Participatory planning; Urban water supply management; Decision support framework; Action research; Water engineering; Vattenteknik;

   Sammanfattning : In this study, four real-life problem situations were used to explore the challenges of developing and implementing decision support tools for planning and management within an urban water utility. The study sought to explore how the degree of adoption of formal decision support tools in practice, generally perceived to be low, could be improved. LÄS MER

   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

4. 3. Decision support for sustainable water security

   Författare :Karin Sjöstrand; Dale Whittington; RISE; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; risk assessment; decision support; water security; water availability; multi-criteria decision analysis; water scarcity; sustainability; drinking water supply; cost-benefit analysis; marginal abatement cost curves;

   Sammanfattning : Society’s large dependence on water, in combination with climate, socio-economic and demographic changes, places a massive pressure on our freshwater resources. As a result, water crisis, defined as a significant decline in the available quality and quantity of freshwater, is now considered to be among the most critical global risks to society. LÄS MER

5. 4. Water Supply in Tanzania and Performance of Local Plant Materials in Purification of Turbid Water

   Författare :Nancy Marobhe; Gunno Renman; Gunnar Jacks; Msafiri Jackson; Tapio Katko; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Antibacterial effect; Coagulant proteins; Vigna unguiculata; Parkinsonia aculeata; Ion exchange; Tanzania water supply; Water engineering; Vattenteknik;

   Sammanfattning : Water supply services in urban and rural areas of Tanzania were reviewed and specific studies were carried out on water supply and on purification of turbid water sources using locally available plant materials in rural villages of Singida Rural District. The review showed that large proportions of urban and rural populations in Tanzania face acute water supply problems mainly due to poor planning, implementation and management of water supply projects, including an inability to address social, technical, operation and maintenance and financial issues.
