Abstraction, diversion, and storage of flow alter rivers worldwide. In this context, minimum regulations are applied to mitigate adverse impacts protect affected river reaches from environmental deterioration. Mostly, however, only selected instream criteria considered, neglecting the floodplain as an indispensable part fluvial ecosystem. Based on essential functions processes unimpaired temperate rivers, we identify fundamental principles which must adhere determine truly...
Rivers worldwide have been transformed into fragmented, impounded, channelized, and flow-regulated ecosystems. These anthropogenic transformations can reduce fish distribution population status, especially of those species belonging to medium- or long-distance migratory guilds dependent on free-flowing rivers intact sediment habitat conditions. Here, we aim understand how different hydro-morphological pressure types affect the status key potamodromous rheophilic lithophilic guilds, barbel (...
Hydropower (HP) is an important renewable energy source contributing 65.7% to Austria's national electricity generation. However, HP also associated with ecosystem degradations jeopardizing the aims of EU Water Framework Directive (WFD) and Habitats Directive. Based on Renewable Energy (RED), Austrian Strategy has defined goals further increase production by 3.5 TWh until 2015. Because strategies for development are widely missing, hydropower plants (HPPs) planned approved a local regional...
In today’s intrinsically connected world, the Water–Food–Energy–Climate Nexus (WFEC Nexus) concept provides a starting point for informed and transparent decision-making based on trade-offs synergies between different sectors, including aquatic ecosystems, food security, energy production, climate neutrality. The WFEC approach is particularly applicable in regions requiring transboundary water management, such as Central Asia. Unfortunately, this region with unevenly distributed...
Europäische Fließgewässer stehen unter starkem Nutzungsdruck. Dabei zählen Eingriffe in die Hydromorphologie im Rahmen energiewirtschaftlicher Nutzung oder durch Hochwasserschutzmaßnahmen zu den stärksten Belastungen. Heute gibt es nur noch wenige verbleibende natürliche naturnahe Gewässerstrecken. In Österreich befinden sich derzeit 15 % der Wasserkörper einem "sehr guten" und 22 "guten" ökologischen Zustand. Um Ziele EU-Wasserrahmenrichtlinie erreichen, sind Nationalen...
Ecological connectivity is key to maintaining a coherent and resilient network of protected areas in the EU. The EU Biodiversity Strategy for 2030 has identified unhindered movement species, nutrients ecological processes across connected landscapes as feature Trans-European Nature Network (TEN-N) conserved areas. However, date, streamlined guidance on planning implementing measures specifically at European scale been limited. This report presents methodological framework guidelines mapping...
This milestone report compiles mid-term findings from the six case studies of NaturaConnect project, each serving as a critical testing ground to understand practical implications TEN-N across diverse environmental and socio-political contexts different spatial scales. These reports represent starting point for identifying commonalities challenges among studies, offering guidance on design implementation TEN-N.
Aquaculture is the fastest-growing animal food production sector and expected to become increasingly important meet future demands. As a landlocked country, Austria’s self-sufficiency rate for fish rather low with 6% in total 48% freshwater fish. Therefore, order enable sustainable growth of while avoiding negative impacts on aquatic ecosystem other uses, we developed aquaZone, decision support tool trout farm zoning. Thereby, 30 spatially explicit criteria related environmental...

Zusammenfassung Im Rahmen dieser Arbeit wurden Abflusskennwerte für Hochwasser (MJHQ), Mittelwasser (MQ) sowie Niederwasser (MJNQ, MJNQ 7 , Q 95 98 ) alle topografischen Einzugsgebiete der österreichischen Oberflächenwasserkörper inklusive ausländischen hydrologischen Oberlieger-Regionen vorhergesagt. Die Regionalisierung wurde mit dem Machine-Learning-Modell XGBoost durchgeführt. Zentrale Grundlage das Training von war LamaH-Datensatz, welcher 859 beobachtete in Zentraleuropa über 70...
Zusammenfassung Weltweit ist die Aquakultur der am schnellsten wachsende Sektor in tierischen Lebensmittelproduktion. Dieser wird voraussichtlich immer wichtiger werden, um den zukünftigen Nahrungsmittelbedarf zu decken. Im Binnenland Österreich Selbstversorgungsgrad von Fisch mit 6 % insgesamt bzw. 48 bei Süßwasserfischen eher gering. Um ein nachhaltiges Wachstum des Sektors ermöglichen und gleichzeitig negative Auswirkungen auf verwendeten aquatischen Ökosysteme andere Nutzungen Ressource...
