Veröffentlichung Shaping sustainable digitisation(Umweltbundesamt, 2021) Arenhövel, Dorothee; Blum, Christopher; Cohors-Fresenborg, Dieter; Eick, Martina; Frien-Kossolobow, Lisa; Hagenah, Evelyn; Kiso, Claudia; Herrmann, Bianca; Koller, Matthias; Hoyer, Christian; Kohlmeyer, Regina; Köhn, Marina; Krack, Juri; Kristof, Kora; Lorenz, Andreas; Löwe, Christian; Menger, Matthias; Douglas, Martyn; Meurer, Doris; Mutert, Tina; Oehme, Ines; Schäfer, Marco; Schauser, Inke; Schlippenbach, Ulrike von; Schlippenbach, Ulrike von ; Schneider, Christian; Schultz-Krutisch, Thomas; Schweitzer, Christian; Sedello, Cornelia; Veenhoff, Sylvia; Töpfer, Christoph; Vogel, Julia; Wachotsch, Ulrike; Weiß, Ralf; Deutschland. UmweltbundesamtDigitisation is not only transforming our society it is also having an impact on the environment: On the one hand, digitisation can improve the state of the environment for example through digitally optimised production processes. On the other hand, negative environmental rebound effects can arise, like a higher demand for internet-enabled products from which an increase in usage of resources and energy during production processes results. With this impulse paper, UBA shows where digitisation can create opportunities and challenges for environmental policy. In doing so, UBA aims to help shape digitisation in line with the guiding principle of sustainability.

UmweltbundesamtWith the indicator report "Data on the Environment - Environmental Monitor 2020", the German Environment Agency provides a condensed picture of the state of the environment, the causes of environmental pollution and starting points for improved policy action. For this purpose, a total of 30 important environmental indicators were selected and, where available, underpinned with existing political goals - for example, from the German sustainability strategy or EU directives. In summary, the system of environmental indicators provides a stocktaking of German environmental policy.

ESTIMAP ("Ecosystem Service Mapping Tool") is a collection of spatially explicit models, originally developed to support policies at a European scale. We based our analysis on 10 case studies, and 3 ES models. Each case study applied at least one model at a local scale. We analyzed the applications with respect to: the adaptation process; the "precision differential" which we define as the variation generated in the model between the degree of spatial variation within the spatial distribution of ES and what the model captures; the stakeholders' opinions on the usefulness of models. We propose a protocol for adapting ESTIMAP to the local conditions. We present the precision differential as a means of assessing how the type of model and level of model adaptation generate variation among model outputs. We then present the opinion of stakeholders; that in general considered the approach useful for stimulating discussion and supporting communication. Major constraints identified were the lack of spatial data with sufficient level of detail, and the level of expertise needed to set up and compute the models. © 2017 The Authors.

At the same time, one could observe a sharp decline in farmland-biodiversity. © Springer International Publishing AG, part of Springer Nature 2019Veröffentlichung Selected Trade-Offs and risks associated with land use transitions in central Germany(2019) Priess, Jörg A.; Hoyer, Christian; Jäckel, Greta; Schweitzer, ChristianFuture uncertainties and risks for socio-environmental systems are often addressed in the form of scenarios. This study aims to identify the biggest future risks and uncertainties for the study region Central Germany and the question which land use changes and impacts on selected ecosystem services related to agricultural production can be expected in the coming decades. For this purpose, we co-developed scenario storylines along the largest uncertainties, how the region may change with different stakeholders and used environmental models to simulate land-use changes and impacts on selected ecosystem services related to agricultural production. The study revealed that Climate change may have beneficial (e.g. maize, sugar beet) or adverse effects (e.g. barley, wheat) on crop yield levels, depending on crop type and level of climate change. In the scenarios crop production is additionally influenced by different levels of regional preferences influencing crop land extent (e.g., afforestation), crop management (e.g., organic production), and crop types used for food or bioenergy production. As driving factors such as climate change, land availability, and land management all influence agriculture, integrated studies like this are needed to assess future crop production. However, sustainability objectives may prefer other than the most productive agricultural pathways providing additional benefits such as regulating or cultural services. © Springer International Publishing AG, part of Springer Nature 2019Veröffentlichung Daten zur Umwelt(Umweltbundesamt, 2021) Aubrecht, Elisabeth Lena; Balzer, Frederike; Biewald, Anne; Bilharz, Michael; Bünger, Björn; Dauert, Ute; Drosihn, Detlef; Dziekan, Katrin; Eckermann, Frauke; Frerk, Michel; Gniffke, Patrick; Golde, Michael; Günther, Jens; Hermann, Sebastian; Hilliges, Falk; Hintzsche, Matthias; Hofmeier, Maximilian; Hoyer, Christian; Huss, Nadine; Kessinger, Susan; Kolodziej, Andrea; Langholz, Christian; Leujak, Wera; Leuthold, Sandra; Mohaupt, Volker; Müller, Felix; Neuberger, Alexander; Plaß, Dietrich; Reißmann, Daniel; Scheuschner, Thomas; Schulz, Alexandra; Schwermer, Sylvia; Tambke, Jens; Timme, Stephan; Töpfer, Christoph; Werner, Stefanie; Wintermeyer, Dirk; Deutschland. UmweltbundesamtMit dem Indikatorenbericht "Daten zur Umwelt - Umweltmonitor 2020" gibt das Umweltbundesamt einen umfassenden Überblick über den Umweltzustand, über die Verursacher der Umweltbelastungen und Ansatzpunkte für verbessernde Maßnahmen. Dazu wurden für alle Umweltbereiche insgesamt 30 wichtige Umwelt-Indikatoren ausgewählt und soweit vorhanden mit vorliegenden politischen Zielen - beispielsweise aus der deutschen Nachhaltigkeitsstrategie oder auch aus EU-Richtlinien - unterlegt. Daher stellt das System der Umweltindikatoren gleichzeitig eine Bilanz der Umweltpolitik dar.

UmweltbundesamtDie Digitalisierung transformiert nicht nur unsere Gesellschaft, mit ihr gehen auch Auswirkungen auf die Umwelt einher: Einerseits kann Digitalisierung den Umweltzustand verbessern, z.B. durch digital optimierte Produktionsprozesse. Andererseits können negative Umwelteffekte entstehen, da z. B. der Bedarf an internetfähigen Produkten zunimmt, die bei der Produktion und der Nutzung weitere Ressourcen und Energie benötigen. Mit diesem Impulspapier zeigt das UBA auf, wo durch Digitalisierung Chancen und Herausforderungen für die Umweltpolitik entstehen können. Damit möchte das UBA dazu beitragen, Digitalisierung im Einklang mit dem Leitbild der ⥠Nachhaltigkeit⥠zu gestalten. Quelle: www.umweltbundesamt.de
