The Strategies to Improve Water Quality from Managed Peatlands (SWAMP) research project aimed to address key knowledge gaps about water quality degradation in Ireland's peatland areas. This degradation is caused by decades of drainage for industrial and domestic peat extraction. The project reveals how long-term drainage for peat extraction and other land uses have negatively impacted Ireland's rivers and streams. Drained peatlands have leached harmful nutrients, acids, and carbon-rich water into these water bodies. The research focuses on identifying pollution hotspots, measuring the effects of peat soil drainage on water chemistry and aquatic biodiversity, assessing pollution prevention measures, and developing better hydrological models to predict the response of peatlands to drainage and restoration. These findings come at a crucial time as Ireland must address the specific challenges of complying with the Water Framework Directive and fulfilling the Nature Restoration Law.

Research 488: Habitat Mapping, Assessment and Monitoring with High-resolution Unoccupied Aerial Vehicle Imagery (iHabiMap)
Authors: John Connolly, Charmaine Cruz, James R. Martin, Jerome O Connell, Kevin McGuinness and Philip M. Perrin, June 2025
Year: 2025
Ireland has a wide range of important habitats, identified under Annex I of the EU Habitats Directive, needing protection and restoration. Monitoring, reporting, and verifying these habitats is an essential activity under this directive, but this can be time-consuming and resource-intensive, particularly over large remote areas. This research (iHabiMap) has enhanced our ability to do this by integrating ecological and UAV surveys, image analysis, and machine learning to accurately map coastal, grassland, and upland habitats. iHabiMap produced habitat maps with over 90% accuracy, demonstrating the potential of UAV and AI technology in habitat monitoring. The methodology can support regular habitat assessments, is transferable to other habitat types, and can help monitor the degradation and rehabilitation of dune systems, salt marshes, uplands, and grasslands. The agile research methodology was also adapted to map and monitor the invasive species Spartina anglica in saltmarshes.

Research 486: Proactive Optical Monitoring of Catchment Dissolved Organic Matter for Drinking Water Source Protection (PRODOM)
Authors: John Weatherill, Boris Droz, Elena Fernández-Pascual, Jean O’Dwyer, Emma Goslan, Connie O’Driscoll and Simon Harrison, May 2025
Year: 2025
In Ireland, approximately 82% of public water supplies originate from surface water catchments. This water requires disinfection with chlorine to inactivate pathogens and prevent the spread of waterborne disease. The presence of dissolved organic matter (DOM) in source waters can lead to the formation of potentially carcinogenic disinfection by-products (DBPs), such as trihalomethanes (THM4), of which Ireland has the highest number of reported exceedances in the EU in recent years. This research conducted detailed field and laboratory investigation in the River Lee catchment (Cork, Ireland), supported by predictive modelling using machine learning techniques, to gain more insights in the role of optically active DOM in DBP formation and forecasting. It highlights the value of UV-visible spectroscopy as a cost-effective and non-destructive technology suitable for proactive management of DOM in source water, with a high potential for aiding real-time process control at treatment plants.

Research 485: Specific Management and Robust Targeting of Riparian Buffer Zones
Authors: Daire Ó hUallacháin, Per-Erik Mellander, Simon Parker, Nikki Baggaley, Mark E. Wilkinson, Allan Lilly and Marc Stutter, April 2025
Year: 2025
With many of Irelands surface waters classed as less than the minimum of “good ecological status” under the Water Framework Directive, this research project looked to support optimal targeting and management of riparian margins, in agricultural contexts, for effective management of rivers in Ireland. It delivers a riparian measures database summarising alternative measures for Irish conditions, evaluating their effectiveness and wider ecosystem service benefits. Core to the research is the “Right Measure, Right Place” concept, a key tenet of Ireland’s River Basin Management Plan (2022–2027). Tools were developed to identify locations for maximum impact, using landscape context to prioritise 16 identified mitigation measures. The project aims to help policymakers and other research projects expand beyond traditional approaches to achieve water quality objectives under policies like the Common Agricultural Policy and Water Framework Directive.
Research 484: Framework for Characterising Oligotrophic (3110 and 3160) Lakes Using Practical Methods and Assessment Tools
Authors: Heather T. Lally, Martin Gammell, Emma Gray, Giovanni Cappelli and Cilian Roden, April 2025
Year: 2025
Oligotrophic lake habitats, which are characterised by low accumulation of dissolved nutrient salts are protected freshwater habitats in Ireland. These habitats support limited life forms, mainly algae and macroinvertebrates. This research report, from the "Peat Lakes" project, looks at the potential of these organisms to help in characterising and conserving oligotrophic lakes using practical methods and assessment tools. It assesses and provides findings on water chemistry and data from plant communities, including macrophytes, algal communities (including desmids), and invertebrate communities from 24 water bodies within Atlantic blanket bog landscapes in the west of Ireland. The report makes several recommendations and provides relevant stakeholders from state agencies with important information for the conservation of small water bodies (area ≤ 0.01 km²), to support the monitoring of favourable conservation conditions in oligotrophic lake habitats, under the EU Habitats Directive.
Research 483: Just Resilience and Adaptation in Ireland (JustAdapt)
Authors: Stefano Ceolotto, Niall Farrell, Pranav Kakkar and Anita Vollmer, April 2025
Year: 2025
Both the impacts of climate change and the policy responses to mitigate emissions affect different sections of society in different ways. The JustAdapt research project is the first national-level study to consider socioeconomic vulnerability alongside climate change impacts at a local level in Ireland. It includes modelling extreme weather events to identify where climate impacts and socioeconomic vulnerability coincide, assessing local economic impacts of climate policies, and developing guidelines for incorporating nature-based solutions, equity and justice into climate policy decision-making. Overall, the research offers policymakers, planners, and stakeholders’ insights to design fair, effective, and sustainable climate adaptation policies and strategies, while considering socio-economic vulnerabilities and promoting nature-based solutions for a resilient future.

This research report explores improving water quality affected by agricultural practices using a multi-disciplinary approach .It incorporated systems analysis of actors and incentives, spatial analysis on the effects of rural activity, analysis of factors impacting measure adoptions, and socio-economic and behavioural psychology studies to identify drivers of pro-environmental activity. Key findings highlight the necessity of localised solutions, the importance of farm advisors and local farming 'champions', collaboration among stakeholders, and providing knowledge and resources to farmers. It also finds that trust between advisors and farmers, upskilling advisors, and understanding the direct and indirect barriers to farm-level behaviour change are seen as crucial for fostering sustainable agricultural practices. The researchers highlights the importance of incentives and behavioural interventions to promote pro-environmental practices.
Evidence Synthesis Report 5: Study of the Increased Risk of Corrosion with the Use of Fatty Acid Methyl Ester (FAME) as a Diesel Additive
Authors: Carmel Breslin, Gillian Collins, Tara Barwa and Daniele Alves, March 2025
Year: 2025
Biofuels, including fatty acid methyl ester (FAME)-based biodiesels, have the potential to reduce greenhouse gas emissions from our transport sector. However, as these FAME-based biodiesels have become more common, challenges related to storage issues have emerged. FAME is not compatible with all materials, and corrosion issues have been reported during longer-term storage. This evidence synthesis research examines the properties of FAME-based biodiesels, the nature of corrosion reactions associated with these biofuels, the potential risk of corrosion and how to mitigate the risk. The report provides guidance on the general protocols to follow when managing and storing FAME-based biodiesels to mitigate corrosion risks.
