In this study, we explored how barriers such as dams have affected the longitudinal connectivity of riverine habitats from perspective potamodromous fish. For purpose, changes are investigated in central part Austrian Danube system, where national reporting for EU Water Framework Directive provides detailed information on position and characteristics well distribution range native fish species. This assessment is based an estimation regarding quantitative upstream downstream passability individual barriers, further investigate three different scenarios to account uncertainties. We then apply several combinations assumptions dispersal distances calculate a series network-based reach catchment indices. On average, barrier indicated high passability, while was substantially lower across scenarios. Furthermore, existing passes were estimated increased average between 20 % 24 %.

A Holistic Catchment‐Scale Framework to Guide Flood and Drought Mitigation Towards Improved Biodiversity Conservation and Human Wellbeing

Wiley Interdisciplinary Reviews Water, Год журнала: 2025, Номер 12(1)

ABSTRACT As climatic extremity intensifies, a fundamental rethink is needed to promote the sustainable use of freshwater resources. Both floods and droughts, including water scarcity, are exacerbating declines in river biodiversity ecosystem services, with consequences for both people nature. Although this global challenge, densely populated regions such as Europe, East Asia North‐America, well most affected by climate change, particularly vulnerable. To date mitigation measures have mainly focused on individual, local‐scale targets, often neglecting hydrological connectivity within catchments interactions among hydrology, biodiversity, change human wellbeing. A comprehensive approach improve infiltration, retention groundwater recharge, thereby mitigating impacts heavy rainfall droughts scarcity. We propose holistic catchment‐scale framework that combines conventional civil engineering methods, nature‐based solutions conservation actions. This integrates legislation, substantial funding governance structure transcends administrative discipline boundaries, enabling coordinated actions across multiple spatial temporal scales. It necessitates collaboration local regional stakeholders citizens, scientists practitioners. vision management resources could synergistic effects support mitigate functional ecosystems deliver benefits people.

Fast Expansion of Surface Water Extent in Coastal Chinese Mainland from the 1980s to 2020 Based on Remote Sensing Monitoring

Water, Год журнала: 2025, Номер 17(2), С. 194 - 194

Опубликована: Янв. 13, 2025

High-resolution satellite imagery providing long-term, continuous information on surface water extent in highly developed regions is paramount for elucidating the spatiotemporal dynamics of bodies. The landscape bodies a key indicator quality and ecological services. In this study, we analyzed dynamics, including rivers, lakes, reservoirs, using Landsat images spanning from 1980s to 2020, with focus Coastal Chinese Mainland (CCM) region. Our objectives were investigate temporal spatial variations area characteristics, explore driving forces behind these variations, gain insights into complex interactions between evolving environmental conditions, ultimately support sustainable development coastal regions. findings revealed that reservoirs constitute largest proportion water, while lakes occupy smallest share. Notably, trend expansion CCM was observed, mainly construction new reservoirs. These primarily gained areas agricultural land river floodplains early stages (1980s–2000), greater encroached upon by later periods (2001–2020). At level, tendency toward fragmentation complexity particularly evident. Human interference, urbanization, played pivotal role surfaces. While reservoir benefits resource assurance, flood control, prevention, it also poses eco-hydrological challenges, deterioration, reduced hydrological connectivity, aquatic ecosystem degradation. study provide essential data development. underscore urgency importance integrated management strategies, efforts aimed at conservation restoration natural scientific regulation artificial Balancing human needs preservation integrity crucial facilitating strategy integrates climatic socio-economic dimensions, ensuring use protection future generations.

Seeing is believing: How citizen science challenges riparian misconceptions

Open Research Europe, Год журнала: 2025, Номер 5, С. 89 - 89

Опубликована: Март 31, 2025

This open letter discusses the importance of riparian vegetation and misconceptions surrounding its management. It highlights essential ecosystem services provided by zones, such as flood regulation, sediment control, shading, microclimate habitat diversity. Despite these benefits, public misunderstanding often leads to harmful policies like clear-cutting channelization. In this brief communication, we emphasize role citizen science in addressing perception involving local communities environmental surveys, providing examples a novel approach monitor manage forests. This newly developed process involves volunteer training, data collection using smartphone app, analysis, dissemination results. The collected is validated experts used inform decision-making. hands-on engagement helps replace anecdotal beliefs with evidence-based understanding, fostering better support for conservation efforts.

A social network analysis of the European science–policy–society interface on biodiversity

Abstract Despite the wealth of evidence on biodiversity status, trends, and policy options in Europe, knowledge often fails to inform makers decision effectively. Implementing EU Biodiversity Strategy for 2030 will require transformation engagement exchange between providers makers. This is one main goals forthcoming Science Service Biodiversity. We sought support this endeavor by mapping landscape actors at science–policy–society interface. first compiled an extensive database ( n = 215) combining existing databases, searching web, consulting experts. then interviewed representatives key organizations 28) elicit data about their network relations with other organizations.

Slow drawdown, fast recovery: Stream macroinvertebrate communities improve quickly after large dam decommissioning

Journal of Applied Ecology, Год журнала: 2024, Номер 61(6), С. 1481 - 1491

Опубликована: Апрель 24, 2024

Abstract Dam removal is increasingly considered as a river restoration tool for impoundments that harm the environment or have exceeded their lifespan. However, few studies report ecological consequences of large dam removal. We performed multiple before‐after/control‐impact (mBACI) study to investigate decommissioning (42 m high) on instream habitat and invertebrate communities in temperate, forested catchment northern Spain. Before decommissioning, lack fine sediments high concentrations manganese iron occurred below but decreased downstream. Invertebrate taxa richness diversity were reduced, pollution‐sensitive missing just dam. The drawdown reservoir, first step towards its mobilized stored causing frequent turbidity peaks downstream, which nevertheless, caused no detrimental effects macroinvertebrate communities. One year after drawdown, downstream from dam, well those newly formed stream area formerly impounded by became very similar control reaches, showing successful project. Synthesis applications . helps restore habitats facilitates recovery short time frame if there are nearby sources potential colonizers. Slow reduces transport accumulated reservoir impacts, even more prior kept full years promote deposition marginal areas will later be readily colonized trees.
