2. 1. Environmental-flow assessments for current and future run-off in a large river system regulated for hydropower production

   Author : Åsa Widén; Roland Jansson; Birgitta Malm-Renöfält; Michael McClain; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Environmental flows; eco-hydrology; hydropower; river ecosystem; environmental benefits; climate change; collaboration; resource management; Ekologisk reglering; vattenkraft; produktionsoptimering; hydrologi; hydraulik; akvatiskt ekosystem; miljönytta; klimatförändringar; samverkan; vattenresurs management;

   Abstract : In 2019, Sweden implemented legislative changes to renegotiate hydropower permits to both consider environmental rehabilitation and to ensure national supply of hydropower. This means that efforts for environmental rehabilitation of the 2,000 hydropower plants in Sweden need to be considered. READ MORE

4. 2. Strengthening the Environmental Sustainability of Production Systems through Digitalization

   Author : Xiaoxia Chen; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; digital technology; Industry 4.0; digitalization; manufacturing; mechanisms; environmental sustainability; production system; environmental benefits;

   Abstract : Industrial companies are facing incremental pressure to strive for environmentally sustainable development. This can be attributed to their increased contribution to energy consumption and carbon emissions and the growing international attention focused on global warming. READ MORE
