1. 1. Access to water : Rights, obligations and the Bangalore situation

   Författare :Jenny T. Grönwall; Johan Hedrén; Julie Wilk; Srinivasan Janakarajan; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; access to water; rights; human rights; water rights; India; Bangalore; tillgång till vatten; rättigheter; mänskliga rättigheter; vattenrättigheter; Indien; Bangalore; Water in nature and society; Vatten i natur och samhälle;

   Sammanfattning : The city of Bangalore in southern India is undergoing rapid urbanisation and administrative transition. Its growth puts pressure on the available water sources – being mainly the disputed inter-State River Cauvery and the hard-rock aquifers – with ensuing problems of access. LÄS MER

3. 2. Towards Energy-Efficient Drinking Water Production using Biomimicry

   Författare :Simon Isaksson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Filter; Membrane Protein; Supported Lipid Bilayer; Drinking Water; Water Treatment; Silica; Aquaporin; Liposome; Biomimicry;

   Sammanfattning : Water is a prerequisite for life and we therefore need pure drinking water to survive. Yet there are more than half a billion people that do not have access to pure drinking water. Water treatment can be performed in many different ways, one of the most commonly used being filtration.

4. 3. Sustainable Arsenic Mitigation A Strategy for Scaling-up Safe Water Access : A Strategy for Scaling-up Safe Water Access

   Författare :Mohammed Hossain; Prosun Bhattacharya; Marinus Eric Donselaar; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Bangladesh; drinking water; arsenic mitigation; local tubewell driller; sediment color tool; low-manganese; Intermediate Deep aquifer; Land and Water Resources Engineering; Mark- och vattenteknik;

   Sammanfattning : In rural Bangladesh, the drinking water supply is mostly dependent upon manually operated hand pumped tubewells, installed by the local community. The presence of natural arsenic (As) in groundwater and its wide scale occurrence has drastically reduced the safe water access across the country and put tens of millions of people under health risk.

5. 4. Challenges and Opportunities For Safe Water Supply in Mozambique

   Författare :Nelson Matsinhe; Avdelningen för Teknisk vattenresurslära; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; service quality; sustainability.; water treatment; water supply;

   Sammanfattning : In Mozambique, despite considerable investments in the promotion of drinking water supplies, the access to quality water of sufficient quantity for the majority of people is still far from optimal. Current official figures report that nearly half of the country´s population and about 45 per cent of urban residents do not have access to safe water. LÄS MER

7. 5. Basin-scale change in water availability and water quality under intensified irrigated agriculture

   Författare :Rebecka Törnqvist; Jerker Jarsjö; Marcel van der Perk; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Irrigation; Hydrology; Land-use change; Basin-scale; Central Asia; Aral Sea; Semi-arid; Return flow; Water saving; Health risk; Water quality; Surface water; Groundwater; Nitrogen; Attenuation; Recirculation; Climate change; Physical Geography; naturgeografi;

   Sammanfattning : Changes in land use and water use can greatly impact the cycling of water and water-borne substances. Increased redistribution of river water to irrigated fields can cause enhanced evapotranspiration and decreased river discharge. LÄS MER
