1. 21. The use of highway crossings to maintain landscape connectivity for moose and roe deer

   Författare :Mattias Olsson; Per Widén; Anthony Clevenger; Karlstads universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; wildlife crossings; Barrier effect; habitat selection; ecoduct; moose; roe deer; connectivity; conservation; overpass; underpass; highway; exclusion fencing; Biology; Biologi; Biology; Biologi;

   Sammanfattning : Increasingly wildlife managers and land managers are challenged to maintain the viability and connectivity among large mammal populations. Thus, it is important that effective highway crossings are identified and optimized with respect to construction cost, facilitation of ungulate movements, and ability to reduce wildlife-vehicle collisions.

3. 22. Designing out waste - Exploring barriers for material recirculation

   Författare :Isabel Ordonez Pizarro; Chalmers tekniska högskola; []
   Nyckelord :HUMANIORA; HUMANITIES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; waste sorting; sustainable development; Water; Waste; Urban; waste management; Resources; resource recovery; ​Recycling; designing with waste; recycling;

   Sammanfattning : This doctoral thesis has investigated what hinders material recirculation in society, to later suggest possible ways to support material recirculation in the future. Since material recirculation is proposed as a way to use waste materials for new production, it was deemed relevant to investigate two separate case studies that enabled recirculation from production systems and waste management.

4. 23. Marginal and Virtual Water for Sustainable Water Resources Management in Syria

   Författare :Khaldoon A. Mourad; Centrum för Mellanösternstudier (CMES); []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

   Sammanfattning : Arid and semiarid Middle Eastern countries generally, and Syria in particular, face serious water shortage problems and challenges with water sustainability. Climate change, population growth, and economic development play a major role in decreasing available water resources per capita. LÄS MER

5. 24. Exploring cross-resource impacts of urban sustainability measures : an urban climate-land-energy-water nexus analysis

   Författare :Rebecka Ericsdotter Engström; Viktoria Martin; Georgia Destouni; Vladimir Cvetkovic; Mark I. Howells; Nazmiye Ozkan; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; urban sustainability; CLEW nexus; water-energy nexus; nature-based solutions; SDG spillovers; Energy Technology; Energiteknik;

   Sammanfattning : In an increasingly urban world, cities' global resource uses grow. Two fundamental resources for making cities liveable are water and energy. These resources are also closely interlinked – systems that convert and deliver energy to cities require water, and urban water systems use energy. LÄS MER

7. 25. Evaluation of suitable nursery areas for penaeid shrimps in shallow water systems in southern Mozambique

   Författare :Daniela de Abreu; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Tropics; Southeast Africa; Shallow water; Estuaries; Nursery ground value; Decapods; Penaeidae; Carbon and nitrogen isotopes; Diet; Acetyl cholinesterase; Butyryl cholinesterase; Metals;

   Sammanfattning : Tropical shallow water habitats such as estuaries, mangrove forests and seagrass beds are important nursery areas for juveniles of many commercially important species including penaeid shrimp. Penaeids are one of the most important fishery resources worldwide, and in Mozambique they are the basis of a profitable commercial fishery, landing hundreds of tons per year. LÄS MER
