In the last 20 years, the implications of international trade for environmental distribution between North and South gained increasing attention in the debate on sustainable development. In this article, the authors take a biophysical perspective to analyze the distribution of environmental goods versus environmental burdens in North-South trade relations. Studies based on physical accounting are particularly suitable to elucidate environmental consequences of economic specialization processes in different world regions, as they clarify implications for both the use of natural resources and the generation of waste and of emissions in a coherent and comprehensive manner. Empirical evidence from biophysical accounting studies suggests that the formation of specific metabolic profiles of societies in the North and in the South, as a consequence of economic specialization, leads to an unequal environmental distribution. The article closes with an evaluation of policy measures and instruments appropriate for reducing negative environmental consequences of North-South trade.

Global supply chains shift environmental and social impacts of consumption to remote locations. This opacity challenges many sustainability goals. To help businesses and governments realize more sustainable supply chains, new approaches are using spatial data and machine-learning techniques to connect Earth observation data to conventional economic tools.

A rapidly growing share of global agricultural areas is devoted to the production of biomass for non-food purposes. The derived products include, for example, biofuels, textiles, detergents or cosmetics. Given the far-reaching global implications of an expanding non-food bioeconomy, an assessment of the bioeconomy's resource use from a footprint perspective is urgently needed. We determine the global cropland footprint of non-food products with a hybrid land flow accounting model combining data from the Food and Agriculture Organization and the multi-regional input-output model EXIOBASE. The globally interlinked model covers all cropland areas used for the production of crop- and animal-based non-food commodities for the years from 1995 to 2010. We analyse global patterns of raw material producers, processers and consumers of bio-based non-food products, with a particular focus on the European Union. Results illustrate that the EU is a major processer and the number one consumer region of non-food cropland, despite being only the fifth largest producing region. Two thirds of the cropland required to satisfy EU non-food consumption are located in other world regions, giving rise to a significant dependency on imported products and to potential impacts on distant ecosystems. With almost 29% in 2010, oilseed production, used to produce, for example, biofuels, detergents and polymers, represents the dominant share in the EU's non-food cropland footprint. There is also a significant contribution of more traditional non-food biomass uses such as fibre crops (for textiles) and animal hides and skins (for leather products). Our study emphasises the importance of comprehensively assessing the implications of the non-food bioeconomy expansion as envisaged in various policy strategies, such as the Bioeconomy Strategy of the European Commission.

Das Umweltbundesamt veröffentlicht seit dem Jahr 2016 einen Bericht "Die Nutzung natürlicher Ressourcen. Ressourcenbericht für Deutschland". In diesem Ressourcenbericht werden die vielfältigen Zusammenhänge zwischen Ressourcenentnahme, Ressourcenkonsum und wirtschaftlicher Entwicklung untersucht und aufbereitet. Nach den ersten beiden Ressourcenberichten aus den Jahren 2016 und 2018 (⁠UBA⁠ 2016, 2018) wurde im Jahr 2022 die dritte Ausgabe veröffentlicht (UBA 2022). Ziel der vorliegenden Begleitmaterialien, bestehend aus einem Begleittext und einer Power Point Präsentation, ist es, ausgewählte Inhalte aus dem Ressourcenbericht zusammenzufassen, um z. B. die Nutzung im Lehrbetrieb oder Bildungseinrichtungen zu unterstützen.
