  2. 11. Efficient Management of Water Utilities : Sustainability Analysis of Swedish Performance

    Author : Nasik Najar; Avdelningen för Teknisk vattenresurslära; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sustainability index; reinvestment; facilities status; climate adaptation and flood security; ; water utility in Sweden;

    Abstract : In Sweden, a sustainability index (SI) has been used since 2014 as an internal benchmark management tool to analyse and steer municipal water and wastewater (WW) activities toward sustainability. A consistent trend in national results from SI across all years is that while day-to-day operations are working well, there are deficiencies in strategies for long-term planning. READ MORE

  5. 13. Hydro-climatic changes in irrigated world regions

    Author : Shilpa Muliyil Asokan; Georgia Destouni; Howard Wheater; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Climate change; hydro-climatic change; evapotranspiration; irrigation; water demand; water balance; land-use; water-use; hydrological catchment; Aral Sea; India; Mahanadi River Basin; Physical Geography; naturgeografi;

    Abstract : Understanding of hydro-climatic changes in the world’s river basins is required to ensure future food security. Different regional basins experience different levels of hydro-climatic change depending on the endorheic or exorheic nature of a hydrological basin, along with the climatic conditions and human land and water-use practices, for instance for irrigation.

    Abstract : Water supply security is increasingly becoming a challenge worldwide. Surface waters, which are often used for drinking water production, have experienced an increase in natural organic matter (NOM) and frequency of algae blooms. Water quantity is also an issue due to increasing populations and potable water demand. READ MORE
