DANUBE4all is an EU project with the main task of developing a comprehensive action plan for the renaturation of river stretches in the Danube River Basin (DRB). To this end, a collaborative stakeholder process is being developed that actively incorporates the interests of citizens. The action plan is intended to contribute to the improvement of the ecological status, biodiversity and river connectivity of the Danube ecosystems and thus supports the EU mission OCEAN ‘Mission Healthy Oceans, Seas, Coastal and Inland Waters’. 

The development and implementation of innovative and socially relevant nature-based solutions has a wide range of positive effects. In addition to the improved connectivity of rivers, possible scenarios for floodplains, reducing the risk of floods and droughts, and other socio-economically effective measures are an important focus. Renaturation projects on the Danube are being promoted with the goal of improving the continuity of sediments and positively influencing habitats/biota. These include the Danube National Park east of Vienna, a section of the river in Hungary and a measure on the Danube delta. 

Nature-based solutions must be developed in collaboration with the affected population and supported by them in order to be effective in the long term. Renaturation processes tend to unfold slowly and require continuous attention and active support in order to be successful. Accordingly, the intensive involvement of citizens along the Danube is an important component that makes renaturation possible in the first place. A special work package supports interaction with citizens through the activation of citizen science. Citizen scientists are particularly involved in the development, implementation, evaluation and scaling of nature-based solutions, a citizen science method toolbox, and the development of communication measures. 

In particular, DANUBE4all serves the following research fields: 

• Criteria and indicators for physical connectivity status as a starting point for renaturation options in the Danube catchment. A reflection of existing assessment methods and initiatives contributes to this. 
• Analysing the (ecological) status of water bodies and biodiversity with the aim of expanding the existing transnational biodiversity monitoring with a strong focus on restoration. This includes long-term trends in connection with management and conservation measures associated with renaturation.
• Co-creation, implementation and results monitoring of nature-based solutions implemented in the project in the Danube River Basin. This includes: 
  • 3 restoration interventions with the participation of local residents (3 Demonstration Sites); 
  • the further use and replication of solutions in 5 Associated Regions; 
  • later a multiplication of the approach by supporting 10 restoration measures (10 Synergy Sites). 
• Implementation of socially relevant integrative measures with municipalities in the Danube River Basin. This includes measures that trigger social and economic change, as well as the sustainable, integrative and long-term management of restored ecosystems through public mobilisation and engagement. This is also to be achieved through citizen science.

It is an open secret that hardware operating on our smart devices contains not only plastic, but also conflict materials such as tungsten, tin, tantulum and gold. Technology is therefore not neutral. These resources are mined in conflict regions, assembled to electric circuits under harmful labour conditions and mostly ending up in contaminating landfills. This pollution is best understood as an enactment of ongoing colonial relations to Land. 

Arts-based research methods seize artistic practice to unpack complexity. Through opening up our artistic research project to citizens we want to make this phenomenon tangible. Intersecting Art and Science needs to be an experience of empowerment, of encouragement to find new ways.

This Citizen Science projecttackles sensitive issues through an online game that introduces the player to alternative technologies. Participants in our workshops (at the Technisches Museum Wien, the Academy of Fine Arts Vienna children’s university, Maker Fair Vienna and three Viennese schools) can become players and navigate through different scenes to meet specific characters as avatars. These avatars represent real people from around the world, collaborators in our main research project. Through this form of interactive storytelling young people are invited to become inventors of green and fair hardware themselves, to network among each other and transform their ideas into actual prototypes in the next phase of the project. 

Through the term Ethical Hardware we want to describe technology that does not harm the environment, but embraces restorative practices for the benefit of nature and inhabitants alike.

There are strong social movements among teenage, female* and non-binary creatives who share similar values (Extinction Rebellion, Fridays For Future). Our Citizen Science Project addresses the lack of communication between academia and the youth movement. We would like to explore the creativity and transformative work performed by young citizens, specifically from minorities, by offering a playful entry point to our research. We hope that the visions contributed by CSs will transform our theoretical definition of what imagining future technologies entails, and vice versa give participants the chance to discover alternative futures. This way together we hope to gain the necessary strengths to face this crisis. 

Our research team composed by artists researchers Stefanie Wuschitz and Patrícia J. Reis at the Academy of Fine Arts in Vienna and the citizen scientists will together with the Technisches Museum Wien (TMW), our national research partner, make the research results operative for use in classrooms and after school programs.

The sale of electrical and electronic equipment is constantly increasing and accordingly e-waste has already become the fastest growing waste stream in the world. Our society needs to face this challenge without delay, so the Recycling Heroes project aims to raise awareness about e-waste, especially among students but also in society in general, by combining the principles of the circular economy with citizen science methods.

Participation

As citizen scientists, the students develop a comprehensive questionnaire to ask their family or neighbours what electronic products are used for and over what period of time, and what happens to devices that are no longer used. Afterwards, the students analyse the results of the survey and consider what could be done to ensure proper disposal and increase the recycling rate. In addition, the students look into the development of electronic products that can be used in other current citizen science projects. These new products can be developed, for example, as a mesh-up of e-waste parts and new parts - sustainability is the focus here! Subsequently, the developed and tested prototypes will be duplicated in small numbers and distributed to other partner schools in the project. These schools will use the prototypes to collect data on temperature, noise, humidity and particulate matter in the school environment, for example, and then make them available to Citizen Science projects.

Aims

The project aims to strengthen the students' environmental awareness and recycling culture, as well as their understanding of eco-design and development processes. In addition, the students learn to develop suitable survey instruments and to sharpen their scientific thinking with regard to citizen science.

Plastic Pirates - Go Europe! A Citizen Science Initiative to investigate plastic pollution along rivers

The pollution of beaches and riverbanks in Europe with plastic waste does not stop at borders. Preventing micro- and macroplastics in the environment, addressing this challenge scientifically and researching sustainable materials are therefore tasks we need to work on together across Europe.

Plastic Pirates - Go Europe! was first developed in Germany in 2016. Since January 2022, with the support of the EU Commission, the initiative has been extended to the whole of Europe as a European citizen science action in which school classes and youth groups (young people aged 10-16) collect plastic samples from streams and rivers and document their findings. The data collected across Europe is entered into a database and then analysed by scientists. Young people who are interested in science and the environment are given the opportunity to participate in practical research. They make an important contribution to researching the state of European rivers and the extent and pollution caused by plastic waste.
As part of the project, the types of waste identified by the individual groups (e.g. cigarette butts, pieces of foil or packaging) are recorded on a suitable river bank or stream with the help of detailed action materials and subsequently published on a digital map. The data collected by the young people will help science to gradually close existing research gaps on the occurrence, composition and production of plastic waste.

Interested school classes and youth groups are cordially invited to participate in the initiative. All information about the "Plastic Pirates" can be found on our homepage (www.plastic-pirates.eu/at) or can be obtained by sending an email request to This email address is being protected from spambots.

CrowdWater is a hydrological citizen science project of the University of Zurich. CrowdWater uses an app to collect data about water. No prior knowledge is required to participate.

What is the project about?

CrowdWater stands for independent and reliable data collection by anyone with an interest in water. The observations collected with the CrowdWater app can complement existing measurements and be used for hydrological modeling. The method is being developed in Zurich and will also be used in remote areas and regions with low data availability. 

How can interested citizen participate?

With the CrowdWater app for Android and iOS, participants can collect data on water levels (with physical and virtual staff gauges), soil moisture, the condition of temporary streams, plastic pollution and water body type independently and without measuring devices. New observation stations can be created anywhere in the world or additional observations can be added to an existing station.

In the CrowdWater online game, the data quality of the uploads in the category "virtual staff gauge" is checked and if needed improved by contributing citizen scientists.

What happens with the data?

The data are published anonymously on our homepage and can be used for free for own projects. In the research project, the data is used for hydrological modeling so that its potential can be investigated. Two PhDs have already been completed in the CrowdWater project, and two more PhDs are currently ongoing. Currently, the focus is on temporary streams and water quality observations. The publications that have come out of the project so far can be found here. What the current research team is working on can be read here.
