We translate knowledge into action and awareness while exploring the challenge of our time: the environmental crisis.

arvae Exhibition in Arosa

New perspectives on sustainability

What new perspectives on how to deal with the environmental crisis arise when people from Arosa, scientists and artists work together?

The project “Schpensa” uses the example of the potato to show the the potential of localizing food systems in the Alpine region. It creates a potato garden in the whole village and collects their knowledge about the crop in a constantly growing online archive.

The experimental project “Food is human” grows mushrooms on sewage sludge from Arosa. It expands our idea of (human) waste and offers new ideas about the current food production cycles.

The Project

Rooted in the people. Creating a community of practice

arvae creates spaces for true collaboration between the arts, science, and local communities. It is all about creating the right atmosphere and taking the time to really get to know the passions and practices of each participant in order to discover synergies and develop joint projects beyond institutional boundaries. We maintain a space for organic development of topics and projects across disciplines in close collaboration with the localities we work in.

Our work is deeply personal and rooted in the people, the knowledge, experiences, and stories that shape their locality.

Cultivating ground for authentic collaboration

Our pursuit of a sustainable future devotes us to permeate institutional boundaries and to connect and share knowledge from the arts, science, and regional experts (e.g. farmers, agricultural landowners, forest managers, or local tourism departments) at the sites of where we work.

Acting in local «Kollektivs»

arvaes core is the «Kollektiv»: an 8-month site-specific experiment in collaborative and transdisciplinary work that results in joint projects combating climatic change on a local level. Beyond the «Kollektiv» we host our «am Tisch» dinners and develop public programs contributing to a broader dialogue and network between art and science.



At the core of arvaes work is the «Kollektiv»: an 8-month site-specific experiment in collaborative and transdisciplinary work which is composed of 9-12 artists, scientists, and local (environmental) experts. Working in regions that are facing the effects of climate change the «Kollektiv»-members together with the local community identify urgent topics. arvae creates the conditions and the atmosphere needed to facilitate true and fair collaboration in 3 project phases (research phase, lab phase, production phase).

We are driven by an open and transparent process of knowledge sharing and project development, and we continuously evaluate the social, ecological, and economic impact we are achieving in our host region and the impact we have on how our «Kollektiv»-members and their collaborators relate to transdisciplinary work.

«Am Tisch»

«Am Tisch» is a curated dinner series taking place in intimate, informal settings and acting as a forum for (future) exchange with arvaes transdisciplinary community within, across, and between the arts and sciences. The format has the focus of connecting people over food (for thought) during dinners in unexpected locations for 20 invited guests and always with input from a member of our community, followed by time for conversation.

For our first dinner in this series we invited visual artist Paloma Ayala, who is also a participant in arvae’s first «Kollektiv» in Arosa, to co-host the evening with us. Paloma foraged local ingredients and prepared the meal with her self-made oven, giving our guests a deeper insight into her decolonial cooking and artistic practice.


«Kollektiv» Arosa

Project start in August 2021

The first «Kollektiv» commenced in August 2021 in Arosa, Switzerland. As we’ve learned from our partner Arosa Tourism, the municipality is facing some urgent environmental challenges, such as shifts in seasons, longer summers for itsit’s dependence on winter tourism or shifts in prevalent species in high altitudes. Therefore Arosa embraces the approach of the project to activate and fuel a broader public imagination around these topics. This in mind, the «Kollektiv» has already been up twice and gone through the research and lab phases.

Research Phase

In August 2021 the research phase of the Arosa «Kollektiv» took place. In this first step the «Kollektiv»-members visited Arosa for four days and identified the needs, challenges, and opportunities for potential projects in close exchange with various local (environmental) experts. Here comes a huge shout-out to our wonderful local friends and collaborators who generously gave the «Kollektiv» insight into their work and passions in and for Arosa!

The research phase resulted in the identification of water systems, agriculture, local food production, and sustainable tourism as key topics to develop projects on.

Lab Phase

Based on the information gathered in the research phase, the «Kollektiv» started developing specific project proposals addressing the selected topics. In order to advance the work on the proposals the «Kollektiv»-members have met for another five days in Arosa in September 2021. During this lab phase the «Kollektiv» largely organised their work autonomously, setting their own priorities and workshops in our open space format. There were meetings held between «Kollektiv-members» and local (environmental) experts, we sat at a round table with the Arosa’s major and the director of Arosa Tourism and we had numerous work-sessions, gatherings, and reflections together, further developing the project proposals. After meeting physically in September the «Kollektiv» worked on their project proposals for three additional weeks.

A project advisory group made up of experienced members of our sounding board and network helped us then make a selection for implementation. These were by Name Monica Ursina Jäger, artist, lecturer and research associate at the Institute of Natural Resource Sciences, ZHAW, Pascal Jenny, President of Arosa Tourism, Yvonne Altmann, Mayor of Arosa, Farah Ahmed, Climate Justice Lead at Julie’s Bicycles, London, Lalasia Bialic-Murphy, Lead Scientist at Crowther Lab, ETH, Serayna Solanki, freelance consultant in climate, environment and community participation, London and Céline Oberle, “Organic” Lead at Migros-Genossenschafts-Bund.

Production Phase

From mid-November 2021 onwards the chosen projects will be specified, produced, realised, and, eventually, evaluated. We look forward to sharing their plans and progress here soon.

«Kollektiv» Members

What makes our «Kollektiv» strong is the expertise and passion of its members and the diversity in skills and characters. Meet the «Kollektiv» of artists, scientists, and local (environmental) experts for arvae in Arosa:

Dr. Mark Anthony

Microbial biologist for Crowther Lab, ETH Zürich

Mark is a microbial ecologist and teacher at ETH Zürich. He researches how the diversity of soil microorganisms influences plant development and the sensitivities of ecosystems to global environmental changes. His main motivation to study fungi lies in the fact that many of these organisms form symbiosis with plants through mycorrhizae, and that the composition and diversity of fungi strongly affects forest ecosystems. Despite their importance in ecosystems most fungi live in the soil and are invisible to the naked eye and thus do not garner the same attention as plants and animals in conservation or restoration initiatives. Mark is passionate about making a convincing case for fungal conservation and research because fungi are figurative engines powering nutrient cycles as decomposers and mycorrhizal symbionts, and that we can prepare better for the future by understanding the ecology of fungi and explicitly incorporating them into environmental initiatives. He is fascinated with Swiss forests because they are highly managed and face many contemporary environmental challenges which will be exacerbated by climate change.

Arosa Projects

Schpensa: a growing archive on cultivated crops

The interdisciplinary project «Schpensa» aims to show the potential that lies in the localisation of food systems in the alpine region. It thematises the relationship of the population of Arosa to cultivated plants, each with a view into the past and with a speculative view into the future.

This is prototypically done with the example of the potato. Through artistic and culinary contributions of the «Schpensa» project team, the relationship of our society to the potato shall be questioned and made accessible through emotionally charged experiences. Historical, scientific as well as artistic and culinary contributions will be collected in a growing archive online. These contributions will be developed in a series of events and workshops with the local population, school classes, gardeners and local chefs of Arosa. Among other things, potatoes will be grown together in cooperation with local garden hosts and the Maran Alpine Garden. The harvested crops will be cooked and celebrated at a harvest festival in the fall.

In a broader sense, «Schpensa» aims to use the example of the potato to pose questions about contemporary and sustainable nutrition in the Alpine region. The «Schpensa» project team believes that the future development of global food production depends largely on societies’ ability to adapt to climatic changes and to re-think their dietary habits.

«Schpensa» is the result of a collaboration between Bettina Tschuor, Violetta Burckhardt, Anne-Laure Franchette and Simeon Max.

Food is human. (Re-)imagination of the relationship between man and mushroom

This highly experimental, process-based project aims to grow edible mushrooms (fungi) from human waste in order to investigate current hierarchies in food consumption and production globally and in Arosa. 

Following a site-visit through Arosa’s water system during the research phase and multiple exchanges with the organic garden in Schanfigg, the project group drew strong connections between the underground water-pipe system in Arosa and a fungal network. Based on the great potential of mushrooms to mediate connections, the project takes up one of the issues most discussed by the «kollektiv»: the development and expansion of tourism in Arosa and the urban waste it generates. It offers new perspectives and possibilities on waste generation while addressing the challenges of growing food and sustaining soil health in an alpine region; and the importance of local food production in Arosa. For this purpose, an experiment will be conducted attempting to cultivate edible mushrooms from mainly sewage sand from Arosa’s wastewater treatment plant, which will be made visible through an installation and events in the center of town in Arosa, aiming to expand the idea of what waste can be.

To procure the waste, the project team is working with Arosa’s fountain master, Roland Bürkli. The project is supported by the Crowther Lab, ETH Zürich, who provides facilities to safely remediate the waste and test the growing of edible fungi. This project is the result of a collaboration between Mark Anthony, Paloma Ayala and Nadine Keller with Kläranlage Arosa.


Alexandra Mueller-Crepon


Before joining forces with Tara to start arvae, Alex leveraged her intercultural capacities building platforms and bridges for artists and designers who work with new technology and science. With an academic background in international relations, cultural management and cultural policy in urban development, she has always been interested in where the arts meet other sectors, disciplines and logics. She has dedicated her career to holding space for free artistic practices within these other structures and fostering understanding for the value of other disciplines collaborating with the arts. She has curated cultural content for tech and science platforms, facilitated collaborations between Swiss partners and American universities, and consulted art schools on their interdisciplinary teaching and internationalization strategies. She has also conceptualised and realised both physical and virtual exhibitions between art, science and technology. Furthermore, by facilitating programs for exchange on cultural entrepreneurship and mentoring cultural start-ups, she has developed a sense for the potential that lies between the arts and a market. She believes that we can most effectively make this world a better place by working together and that every fruitful collaboration starts and succeeds in honest human connection. This is what she strives to contribute to with arvae.
