The presented sustainability analysis of the island Samso uses the concept work energy as basis for the assessment of the sustainability. Both the energy flows and material flows can be expressed as renewable or non-renewable work energy and based on energy units. By the developed method it is possible to assess whether the development in a given area; in this case the island Samso is sustainable and furthermore to identify what is needed to make the development sustainable. The method can also be applied to express how much a project proposal, for instance to introduce electrical car on the island will bring the development closer to complete sustainability. In addition is developed an analysis of the carbon cycling which summarizes all the main carbon processes in a carbon cycling model to be able to assess the total net emission of carbon dioxide and methane on the island and the input-output balance of carbon for the island. Samso has introduced renewable energy but it is not ensuring that the carbon dioxide emission is zero because carbon participates in many processes; photosynthesis, decomposition of organic matter, consumption of food by humans and domestic animals and so on. Therefore is the erection of a model that includes all the main carbon processes necessary to reveal the net emission of carbon dioxide and methane and the total carbon balance. The carbon cycling model can be applied to quantify the emissions and the carbon balance at a given time point and how much they may be changed due to a project proposal for instance introduction and electrical cars on the island. The carbon model demonstrates how the carbon dioxide emission has changed from year 1997 where it was 5000 t C per year to 2011 where the uptake was 26 000 t C per year. By proposed projects it will be possible to take up almost 40,000 t C per year in year 2020.
Sven Erik Jørgensen is Professor Emeritus in Environmental Chemistry at the University of Copenhagen. He has received a Master of Science in Chemical Engineering from the Danish Technical University (1958), a Doctor of Environmental Engineering (Karlsruhe University) and a Doctor of Science in Ecological Modelling (Copenhagen University). He is Honorable Doctor at Coimbra University, Portugal and at Dar es Salaam University (Tanzania). He has received the Einstein Professorship of the Chinese Academy of Science. He has in 1975 founded the journal Ecological Modelling and in 1978 ISEM (International Society of Ecological Modelling). He has received several awards, The Ruder Boskovic Medal, The Prigogine Prize, The Pascal Medal, The Einstein professorship at the Chinese Academy of Sciences and many more. He has published 370 papers of which 256 were published in peer-reviewed international journals and he has edited or authored 79 books, of which several have been translated to other languages (Chinese, Russian, Spanish and Portuguese). He has authored a successful textbook in ecological modelling “Fundamentals of Ecological Modelling”. Recently he authored a well-received textbook in system ecology entitled “Introduction to Systems Ecology”. He is the Editorial Board Member of 20 international journals in the fields of ecology and environmental management. He is the President of ISEM and he has been elected member of the European Academy of Science’s, for which he is the chairman of the Section for Environmental Sciences.
