Sustainable Solutions for Planetary Health

ERN-Environmental Engagements: talks

For the first time in the history of humankind the human-induced socio-ecological crises are approaching or crossing planetary boundaries, threatening the very possibilities of survival on Earth. Only rapid and profound changes can steer us to a pathway towards planetary health. In order to make these transitions as safe and as just as possible, certain values and basic principles need to be considered and evidence-based decisions must be made. Thus, to achieve sustainable solutions for planetary health, a plurality of perspectives is required. This is what the “Environmental Engagements: talks”-series hosted by the Environmental Research Network aims at: Giving a platform to researchers from diverse backgrounds conducting cutting-edge environmental research at the University of Vienna, who are ready to engage with a broad audience beyond disciplinary boundaries through highly timely and solution-focused exchanges.

13.10.2021 Nicole Lieger "A Circular Economy – Going Way Beyond Recycling"

Über den Vortrag:
Ressources on this planet are finite. How can we use them, without using them up?
Instead on digging ores out of the ground, and throwing them away after use, we could develop a system where materials are being reused again and again. Where all materials, once mined, stay in circulation.
For that, we need to go far beyond the old approach of thinking about „recycling“ once we‘re standing in front of a garbage heap. We need to start at the beginning, and design products in a way that makes it possible for product parts and materials to be circular. It needs new business models, new infrastructure, new cultural habits.
A number of initiatives are already underway, from EU level to innovative businesses to individuals.
Is it enough? What needs to happen next?

27.10.2021 Atakan Aral "A Computational Approach Towards Early Detection of Micropollutants in Rivers"

Über den Vortrag:
Industrial facilities located in watersheds use large amounts of water for various purposes, and they release it back to the rivers through water treatment plants. Unfortunately, such treatment plants are prone to technical and human failures. In Europe, we have seen several disasters in the last decade, most recently in Finland and Poland. These failures usually go unnoticed for days and result in huge amounts of chemical discharge into rivers. With an automated monitoring and early warning system, similar environmental disasters could be avoided in the future. Among chemical substances, micropollutants are particularly dangerous to water ecosystems as well as human health because of their high toxicity and decay tolerance. This presentation will summarize our efforts towards designing a computational early warning system for micropollutants in rivers, which will locate the source of the pollution within minutes with unprecedented accuracy. To this end, we propose the use of smart sensors (IoT) and artificial intelligence (AI). The sensors will capture continuous data from the river, and the AI model will combine the data with scientific expertise to make predictions in an automated way. A critical constraint is that such a system must have a small ecological footprint so that it will not affect the very same environment it is intended to protect.

17.11.2021 Ulrike Felt "An environmental problem in search for a political solution – The case of the single-use plastic directive"

Über den Vortrag:
The 20th century has frequently been described as the “the plastic age”, plastic being omnipresent and ubiquitous. It exists in all kinds of forms and with multiple functions — the material’s plasticity has allowed it to permanently reshape our material cultures. Yet, it contains all kinds of chemical additives creating harmful effects; it degrades into fragments (microplastics) thus shifting shape and diffusing into the remotest parts of our environment and our bodies; and, plastic accumulates over time constituting what one could call the archives of 20th century “progress”. Taking these complexities as a starting point, this lecture aims at investigating the struggles in European policy arenas over the governance of plastic. Currently, Europe is engaged in intense policy debates — e.g. the EU Plastic Strategy and the Single-Use Plastics directive — trying to address plastic as a matter of public concern and develop adequate responses. We will carefully analyze the ways these policy initiatives conceptualize, narrate and address the plastic issues and propose solutions. Doing this I want to open up an in-depth reflection on the limitation of specific policy framings and invite to engage with the multiplicity of the lives of plastic-in-society and thinking about the solutions so far proposed or already put in place.

Über die Vortragende:
Ulrike Felt is Professor of Science and Technology Studies since 1999, Head of the Department of Science and Technology Studies and of the research platform Responsible Research and Innovation in Academic Practice.

01.12.2021 Thilo Hofmann "Nano in Plant Agriculture: Risks and Opportunities"

Über den Vortrag:
Professor Hofmann´s talk will address natural (NPs), engineered (ENPs) and microplastic(nano) particles (NMPs). The production and use of industrial, agricultural and consumer products leads to the emission of emerging pollutants into the environment such as ENPs and NMPs. Concerns arise over the possibility that ENPs and NMPs might pose a threat to the environment, including drinking water and food supplies. Investigations of ENPs and NMPs are still hampered by the absence of suitable analytical methods that are capable of detecting and quantifying them in complex matrices and at very low concentrations. This knowledge is urgently needed for risk assessment and regulation. Even though many concepts have been developed in nanogeosciences for the fate of natural particles, they are sometimes overlooked for ENPs and NMPs. This talk will address specific aspects concerning the detection and fate of nanoparticles, including natural, engineered and microplastic(nano)particles. It will focus on analytical concepts and knowledge from nanogeoscience, which might be also important to NMPs research. It will address the state of knowledge of using nanotechnology in plant agriculture, and address risks from increasing plastic pollution at agricultural sites.

Über den Vortragenden:

26.01.2021 Stephanie Nitsch "Wind Power from a Civil Law Perspective"

Über den Vortrag:
In view of an increasing demand for renewable energy, the aim of this talk is to address the challenges that civil law poses to the purchase, construction, and operation of renewable power plants. With a special focus on wind power, a central task is to examine challenges of the law of obligations as well as property law. This analysis is performed through the lens of the various actors involved, such as manufacturers, constructors, operators, and landowners. Which concepts and argumentations are advocated, and do they comply with today’s court practice? In response to this question, new approaches and possible solutions under Austrian civil law shall be introduced and discussed.

Über die Vortragende:
Stephanie Nitsch is a lecturer at the University of Vienna and a member of the editorial board of the ‘University of Vienna Law Review’. Until 2021, Stephanie was a research and teaching assistant (post doc) at the Department for European, International and Comparative Law at the University of Vienna. Her research in the fields of comparative private law and private international law adopts an environmental perspective.
