Development: Time to leave GDP behind
Robert Costanza,Ida Kubiszewski,Enrico Giovannini,Hunter Lovins,Jacqueline McGlade,Kate E. Pickett,Kristin Vala Ragnarsdottir,Debra Roberts,Roberto De Vogli,Richard G. Wilkinson +9 more
TL;DR: Gross domestic product (GDP) is a misleading measure of national success as discussed by the authors, and countries should act now to embrace new metrics, urge Robert Costanza and colleagues, and they do not.
Journal ArticleDOI
Modelling and measuring sustainable wellbeing in connection with the UN Sustainable Development Goals
Robert Costanza,Lew Daly,Lorenzo Fioramonti,Enrico Giovannini,Ida Kubiszewski,Lars Fogh Mortensen,Kate E. Pickett,Kristin Vala Ragnarsdottir,Roberto De Vogli,Richard G. Wilkinson +9 more
TL;DR: In this article, the authors investigate alternative methods to relate the SDGs to overall measures of sustainable wellbeing that can motivate and guide the process of global societal change, and propose a sustainable wellbeing index (SWI) that connects with and complements the SDG dashboard.
Journal ArticleDOI
Challenges of Sustainable and Commercial Aquaponics
Simon Goddek,Boris Delaide,Utra Mankasingh,Kristin Vala Ragnarsdottir,Haissam Jijakli,Ragnheidur I. Thorarinsdottir +5 more
TL;DR: In this paper, opportunities that have the potential to fill the gap between research and implementation of commercial aquaponic systems have been identified, and the analysis shows that aquaponics is capable of being an important driver for the development of integrated food production systems.
Journal ArticleDOI
The dissolution of apatite in the presence of aqueous metal cations at pH 2–7
Eugenia Valsami-Jones,Eugenia Valsami-Jones,Kristin Vala Ragnarsdottir,Andrew Putnis,Dirk Bosbach,AJ Kemp,Gordon Cressey +6 more
TL;DR: Apatite dissolution was studied at 25°C in a series of batch experiments carried out within the pH range of 2-7 with or without the presence of aqueous Pb2+ or Cd2+ as discussed by the authors.
Journal ArticleDOI
The mechanism of cadmium surface complexation on iron oxyhydroxide minerals
TL;DR: In this article, the composition and structure of aqueous cadmium sorption complexes on the iron oxyhydroxide minerals goethite, lepidocrocite, akaganeite, and schwertmannite were studied using extended X-ray adsorption fine structure spectroscopy.
