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

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

    Abstract : 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. READ MORE

    Author : Jessica Spijkers; Henrik Österblom; Matthew Osborne; Tiffany Morrison; Graeme S. Cumming; Geoff Dabelko; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fisheries; conflict; environmental security; social-ecological systems; complex adaptive systems thinking; Sustainability Science; vetenskap om hållbar utveckling;

    Abstract : Are international conflicts over fishery resources a growing security concern? High-profile incidences of conflict, diminishing fishery resources and climate impacts on marine systems have made the international community increasingly wary of fisheries conflict. However, we lack knowledge on conflict incidences over time, as well as the contexts in which the conflicts occur, to assess if fisheries conflict is a growing security threat. READ MORE
