Water plays a central connecting role within the climate system, linking meteorological, hydrological, and earth system processes with societal dimensions such as water resource demands and risks associated with pollution, droughts, and floods. Global water challenges are addressed through multiple international agendas related to sustainable development, climate change, biodiversity, and water security. While these agendas share broadly aligned objectives, they differ in scope, scale, and modes of operationalization. Together, they shape how scientific knowledge is mobilized, policies are formulated, and actions are implemented. As the 2030 Agenda approaches its conclusion, there is a growing need to review and map global water agendas in order to better understand their interactions and support more coherent responses to complex water challenges. Rather than viewing global water agendas as parallel and independent efforts, they can be understood as interconnected learning pathways through which shared objectives, knowledge, and practical experience evolve over time. From this perspective, synergies emerge across these learning pathways through reflection, coordination, and exchange between science, policy, and practice. Clarifying how such synergies can be recognized, supported, and strengthened is therefore essential for advancing more integrated and impactful responses to global water challenges. The Strategic UN Synergy Working Group (SUN) operates within the IAHS HELPING Science for Solutions Decade (2023–2032) and aims to strengthen the contribution of hydrological science to international policy processes and practical implementation programmes. Guided by the HELPING paradigm, SUN facilitates bottom-up engagement, open science, and co-creation principles to support learning across scales and the translation of hydrological knowledge into policy and action. This contribution introduces the vision, structure, and core activities of the SUN Working Group, with a focus on understanding global water agendas and supporting synergies through a science–policy–practice approach. SUN builds on the understanding of global water agendas as interconnected learning pathways, and we will illustrate how coordinated learning pathways can help advance more coherent, integrated, and future-oriented global water agenda.

Small retention ponds are increasingly recognised as effective nature-based solutions for managing hydrological extremes in Norway’s agricultural catchments. Typically located in upper catchment areas or at the forest–agriculture interface, these ponds temporarily store runoff during intense rainfall events and snowmelt. In addition to flood mitigation, they provide important co-benefits by reducing soil erosion and sediment transport and by protecting agricultural drainage systems from erosion and overflow during extreme events, thereby supporting long-term soil productivity. Although individual storage volumes are limited, their cumulative impact at the catchment scale can be substantial when retention ponds are strategically distributed across the landscape. This study investigates the potential effects of small retention ponds using process-based hydrological modelling with SWAT+ to support catchment-scale climate adaptation planning in a Norwegian agricultural catchment. SWAT+ enables an improved representation of hydrological connectivity between managed landscapes and the stream network through its flexible spatial structure and rule-based management algorithms. The model is calibrated using a constraint-based approach that integrates both soft and hard data to represent streamflow and sediment dynamics in the Lierelva catchment. Multiple retention ponds are implemented to assess their cumulative effects on streamflow and sediment transport. Finally, the study discusses key challenges associated with modelling catchment–NBS interactions using SWAT+.

Small, superficial rot spots occurring around lenticels postharvest on apple in Norway have not been identified but were assumed to be underdeveloped Neofabraea lesions. Fungal isolation from such spots on fruit from the 2022 season revealed both Neofabraea perennans and Ramularia spp., identified by B-tubulin and ITS sequencing, respectively. In the 2023 season, isolations were made from fruit with spots resembling dry lenticel spot caused by Ramularia mali. The aim of this study was to identify the Ramularia species associated with the postharvest fruit spots in Norway. Multiple gene regions of five Norwegian isolates (E20, E21 from 2022; 13,15 and 18 from 2023) and three reference isolates, R. mali, R. eucalypti, and R. collo-cygni, were sequenced and used for phylogenetic analysis. The Norwegian isolates were distinct from the included reference isolates, but clustered with other Ramularia species. Isolates 13, 18 and E21 clustered with Ramularia vizellae, while isolates 15 and E20 were most closely related to Ramularia phacae-frigidae. Isolate E20 was sequenced using the Oxford Nanopore Technologies MinION platform. Pathogenicity was assessed in a field inoculation study using isolate E21, resulting in typical spot development on inoculated fruit. Ramularia vizellae has previously been reported from dead apple leaf litter and other woody hosts in the Netherlands and Iran, while R. phacae-frigidae was originally described from Phaca frigida in Switzerland. Neither species has previously been reported in association with apple fruit spotting. While Ramularia mali has caused outbreaks on apple in several European countries, recent studies hypothesize that the symptoms may be caused by a species complex with regional variation. The present results identify candidate species contributing to this complex in Norway and highlight the need for further studies to improve species delimitation and pathogenicity.
