  1. 6. Of seagrass and society : Exploring contributions of tropical seagrass meadows to food security

    Författare :Benjamin Jones; Johan S. Eklöf; Lina M. Nordlund; Leanne C. Cullen-Unsworth; Richard K.F. Unsworth; Maricela de la Torre-Castro; Christina Hicks; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Biodiversity; Blue food; Food security; Social-ecological systems; Small-scale fisheries; Seagrass meadows; marinbiologi; Marine Biology;

    Sammanfattning : Conserving biodiversity while simultaneously feeding a growing population is one of the grand challenges of the Anthropocene. Recently, global assessments have shone a light on the importance of the marine environment for the supply of food (often termed blue food), as well as the diverse and many livelihood opportunities associated to it.

  3. 7. Fields of Gold : The Bioenergy Debate in International Organizations

    Författare :Magdalena Kuchler; Björn-Ola Linnér; Johan Hedrén; Eva Friman; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; bioenergy; biofuels; debate; discourse; concept; international organizations; international relations; FAO; IEA; IPCC; energy security; climate change; food security; food vs. fuel; bioenergi; biobränsle; debatt; diskurs; begrepp; internationella organisationer; internationella relationer; FAO; IEA; IPCC; energisäkerhet; klimatförändringar; livsmedelssäkerhet;

    Sammanfattning : The concept of producing energy from biomass has, for the last two decades, occupied attention of policy-makers, private industries, researchers and civil societies around the world. The highly contested and contingent character of the biofuel production, its entanglement in the nexus of three problematic issues of energy, climate and agriculture, as well as its injection into the current socioeconomic arrangements, is what makes it timely to analyse.

  4. 8. Global Phosphorus supply chain dynamics: Sustainability implications for the 21st century

    Författare :Claudiu Eduard Nedelciu; Ingrid Stjernquist; Kristin Vala Ragnarsdottir; Birgit Kopainski; Pål Börjesson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; phosphorus; supply chain; food security; circularity; systems thinking; system dynamics modeling; naturgeografi; Physical Geography;

    Sammanfattning : Phosphorus is an essential yet irreplaceable macronutrient for agriculture and thus plays a key role in global food security. Most of the phosphate fertilizers are produced from phosphate rock, a finite mineral resource that is mined and processed at great environmental and social costs. LÄS MER

  5. 9. Addressing Water, Energy and Food Accessibility towards Achieving Sustainable Development in Katsina State, Northern Nigeria

    Författare :Yahaya Sani; Avdelningen för Teknisk vattenresurslära; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; water; energy; food; Nexus; Accessibility; sustainabie development;

    Sammanfattning : It has become increasingly evident that water-energy-food nexus security is critical to realising the ambitious global goals (SDGs). Demands for water, energy and food have exceeded available supplies in many regions of the world. LÄS MER

  7. 10. Study on the Earth’s Surface Mass Variations using Satellite Gravimetry Observations

    Författare :Hadi Amin; Mohammad Bagherbandi; Lars Sjöberg; Faramarz Nilfouroushan; Martin Horwath; Högskolan i Gävle; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; geodetic reference system; geoid potential; global vertical datum; climate change; global warming; mass change; ice melting; sea-level change; remote sensing; satellite gravimetry; geodetiska referenssystem; geopotential; globala vertikala datum; klimatförändring; global uppvärmning; massförändring; issmältning; havsnivåförändring; fjärranalys; satellitgravimetri;

    Sammanfattning : Our complex planet is continuously undergoing temporal and spatial changes. In this context, ongoing processes in the Earth subsystems (geosphere, biosphere, cryosphere, hydrosphere, and atmosphere) cause changes in the gravity field of the Earth across a wide range of temporal and spatial scales.
