Circular Economy in the EU: Measures and a new Monitoring Framework

The EU has recently published a “Circular Economy Package”, introducing various measures designed to advance the transition to a circular economy. Among these is a monitoring system that can assess progress towards a circular economy. The foundations for this monitoring framework were developed by the Institute of Social Ecology in Vienna in collaboration with the Joint Research Centre of the European Commission in Ispra.

Human impacts on forests and grasslands much larger and older than previously assumed

Human biomass utilization reduces global carbon stocks in vegetation by 50%, implying that massive emissions of CO2 to the atmosphere have occurred over the past centuries and millennia. The contribution of forest management and livestock grazing on natural grasslands to global carbon losses is of similar magnitude as that of deforestation. Currently, these effects are underappreciated in existing global carbon models and assessments of the greenhouse gas emissions (GHG) from land-based production. Without full consideration of land management effects, global climate forecasts and calculations of the GHG effects of future bioenergy policies are error prone, seriously jeopardizing the robust evaluation of measures that would help achieving the 1,5°C target of the Paris Agreement. These are some of the result of a study headed by Karl-Heinz Erb from the Institute of Social Ecology, published in the scientific journal “Nature” on 20.12.2017.

New research shows: Organic farming can make an important contribution to world nutrition

A global conversion to organic farming can contribute to a profoundly sustainable food system, provided that it is combined with further measures, specifically with a one-third reduction of animal-based products in the human diet, less concentrated feed and less food waste. At the same time, this type of food system has extremely positive ecological effects, i.e. considerable reduction of fertilizers and pesticides, and reduced greenhouse gas emissions – and does not lead to increased land use, despite lower agricultural yields. These are the findings of a new study, which included the Vienna-based Department of Social Ecology among its contributors. Results have recently been published in “Nature Communications”.

When forests regrow: ERC Starting Grant for sustainability researcher Simone Gingrich

In many industrialised countries, forests are starting to regrow after centuries or millennia of large-scale deforestation. This appears positive for the global climate system, because forests sequester carbon that would otherwise accumulate in the atmosphere. However, forest regrowth may not necessarily be a viable strategy for climate-change mitigation. Simone Gingrich has been awarded a prestigious ERC Starting Grant and plans to use it to identify and analyse the “hidden emissions” of reforestation processes.

Current insights into social ecology: special issue of the journal ‚Sustainability‘ published

In the last decades social ecology has made important contributions to sustainability research. As the science of societal relationship to nature it evolved in the late 1980s. Today, the approach that understands complex environmental problems to be rooted in the critical relationship between society and nature is regarded to be fundamental for research dealing with sustainable development. Now, with a special issue of the renowned international journal ‘Sustainability’ a comprehensive insight is given to the state of the art of social-ecological research.

Advanced ERC Grant for Helmut Haberl

Grants awarded by the European Research Council are among the most prestigious research prizes European researchers can hope to attract. Human Ecologist Helmut Haberl (Institute of Social Ecology) is the most recent recipient of an Advanced ERC Grant, valued at almost 2.5 million EURO over a period of five years. Together with his collaborators in the Institute of Social Ecology and at Humboldt University, Helmut Haberl will investigate the role of material stocks for the development towards a sustainable society.

Durstige Landwirtschaft: Übermäßige Grundwassernutzung bedroht Lebensmittelversorgung weltweit

Der Anbau international gehandelter Lebensmittel zapft immer größere Mengen an nicht-erneuerbarem Grundwasser an. Dies führt dazu, dass die Grundwasservorräte schrumpfen – die zukünftige Verfügbarkeit von Lebensmitteln und Wasser gerät damit weltweit in Gefahr, warnt ein internationales Forscherteam im Fachblatt „Nature”. Laut den Expertinnen und Experten des University College of London, des Senckenberg, der Alpen-Adria-Universität, der NASA and des International Institute for Applied Systems Analysis, ist die Menge an nicht-erneuerbarem Grundwasser, das zur Bewässerung genutzt wird, von 2000 bis 2010 um knapp ein Viertel angestiegen.

The century of material stockpiling: 23-fold increase in material stocks in buildings and infrastructure drives resource consumption

A team of researchers led by scientists from the Institute of Social Ecology at AAU has recently presented the first global estimate of the volume of natural resources accumulated in buildings and infrastructure. According to their calculations, global in-use stocks of materials rose 23-fold between 1900 and 2010, harboring long-term consequences for loop closure and emissions.

Vom Luchs bis zur Lungenflechte: Wo die wilden Kerle wohnen

„Buch der Wildnis“ liefert Überblick über Österreichs letzte unberührte Naturräume

Gebäude, Straßen, Menschenmassen, Schmutz und Lärm – je hektischer unsere Welt wird, desto mehr wächst die Sehnsucht der Menschen nach ruhigen, naturbelassenen Rückzugsräumen. „Die Begriffe „Unverfälschte Natur“ oder „Wildnis“ erzeugen allerhand Bilder im Kopfkino, aber was sich dahinter konkret verbirgt, wissen wohl die wenigsten“, sagt Karin Enzenhofer vom WWF. „Wir wollen das ändern und einem besonderen Naturschatz ein Gesicht verleihen: der heimischen Wildnis. Das „Buch der Wildnis“ portraitiert 50 besonders naturnahe, kaum erschlossene Gebiete Österreichs. Leserinnen und Lesern erhalten Einblick in die Schönheit, den Wert und die Verletzlichkeit dieser einzigartigen Landschaften. Das Buch ist zum kostenfreien Download auf erhältlich. Studie zeigt: Viel wilde Natur in den Alpen
