Starting from the first one, in the top left, Professor Fenoglio is seen showing an entomological collection to elementary school children. The second photo depicts staff conducting a fish population survey in the no-kill area of the Po Valley. The third photo shows the no-kill section of the Val Varaita, where sediment flushing has left the riverbed entirely covered with gravel and fine sediment. Finally, the fourth image is an underwater shot showing the release of some trout captured during a survey in the no-kill section of the Po Valley.

Local Activities

ALPSTREAM plays a significant role in the Po Valley area and beyond, promoting activities aimed at protecting watercourses, particularly alpine ones, from both human-induced and natural impacts.

ALPSTREAM has conducted several studies on the effects of sediment flushing, climate change, and anthropogenic impacts related to pollution, excessive water extraction, and habitat destruction. Through this work, the center has become a key player in risk assessment, environmental impact evaluation, water resource management, and biodiversity conservation. It provides consultancy services and collaborates with public authorities and natural parks.

These important partnerships led to the creation of a no-kill fishing area of approximately 3 km on the Po River, the construction of an in-situ mesocosms for manipulative experiments under controlled conditions, and the development of several academic courses, summer schools, educational and research projects, educational excursions, and various other scientific outreach activities.

Additionally, the ALPSTREAM center has made the municipality of Ostana a hub for all activities related to alpine watercourses, hosting schools of different degrees, universities, public authorities, as well as serving as a reference point for fishermen and naturalists. These activities as well as the combined efforts to renew characteristic alpine villages, has led to a growing presence in the area, making it vibrant from a scientific, cultural, and artistic perspective, nationally and internationally. This mutual exchange between science and tourism creates a virtuous cycle beneficial for the economic recovery of the mountain areas. It also offers a new perspective on conducting research immersed in nature, in a context where sustainability is a lifestyle choice aimed at safeguarding the natural wonders of our alpine ecosystems.

Educational Activities with Schools

ALPSTREAM organizes educational activities for all school degrees designed and delivered by trained and qualified staff. These activities stand out for their interactive, multisensory, and interdisciplinary approach, addressing topics related to the protection and study of water bodies, especially alpine rivers. The main topics include the proper management of river systems and water resources,...

Conservation Effectiveness of No-Kill Management for the Protection of River Fish Populations

Canalizations, pollution, dams, water diversions, the exponential increase of cormorant populations, reckless introduction of alien species, and, in recent years, widespread alterations in water flow due to climate change have severely reduced the natural heritage of our rivers. In this context, what is the conservation effectiveness of introducing a no-kill management approach for the protection...

Effects of the Sampeyre Dam Drawdown Operations near the Historic No-Kill Stretch on the Varaita Stream: The photo shows the riverbed significantly impacted by the accumulation of fine sediment.

Sustainable Management of Dam Drawdown Operations

The assessment and mitigation of the impacts of dams on river ecosystems is one of the main research lines of the Centre for the Study of Alpine Rivers – ALPSTREAM. ALPSTREAM researchers have been studying for years the effects of excessive fine sediment accumulation on the biological components of alpine watercourses. In this context, a specific biomonitoring index has been developed, offering...

UNIGHT

For several years now, researchers from the Alpstream group have enthusiastically participated at the European Researchers' Night (Unight), an event held simultaneously across Europe to promote interaction and dialogue between the scientific the community and the society. The goal is to bring citizens closer to science and show how this profession can be exciting, with the aim of inspiring younger...
