   Sammanfattning : The transition to a more biobased society introduces both new opportunities and new challenges as we replace nonrenewable materials with renewable alternatives. One important challenge will be to control microbial growth on materials, both to protect the materials from biological degradation and to prevent the spread of infections and toxins that can cause illness.

4. 18. Decision Support Model for a Sustainable Regional Water Supply

   Författare :Karin Sjöstrand; Chalmers tekniska högskola; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; multi-criteria decision analysis; inter-municipal cooperation; drinking water supply; cost-benefit analysis; decision support; regionalization; sustainability; economic valuation;

   Sammanfattning : Water supply provision has traditionally been a municipal responsibility. However, environmental, social and economic drivers are now making it more attractive to manage the water services in a more aggregated way. LÄS MER

5. 19. 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

7. 20. Monitoring and Evaluation of Rural Water Supply in Uganda

   Författare :Andrew Quin; Berit Balfors; Cecilia Öman; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; monitoring and evaluation; rural water supply; Uganda; Sub-Saharan Africa; Water engineering; Vattenteknik;

   Sammanfattning : Many nations in Sub-Saharan Africa, supported by donors, have increased efforts in their rural water supply programmes within the last few decades. However, these programmes suffer from a range of challenges and problems and, according to recent figures, over half of rural inhabitants in Sub-Saharan Africa lack access to safe water supplies.
