Community-led partnership for coastal restoration in the Maharees peninsula, Ireland

The Maharees peninsula is highly vulnerable to the impacts of climate change. According to the National Risk Assessment 2024 for Ireland , the frequency and intensity of extreme weather events and natural disasters will change due to climate change. Updated high-resolution Climate Projections for Ireland indicate that autumn and winter will become wetter (increases of up to 10% for SSP5-8.5, 2071–2100), while summer is projected to become drier (decreases of 8% for SSP5-8.5, 2071–2100). In addition, substantial increases in heavy rainfall events are expected. The number of intense storms is projected to increase over the North Atlantic Region, and storm surges could occur more often. In combination with sea level rise, there is a higher risk for coastal flooding (see the Climate Change Sectoral Adaptation Plan for Flood Risk Management ). Larger waves, which have reportedly already increased by 0.8 m in height per decade also contribute to increasing risks for coastal communities. Coastal erosion is therefore likely to accelerate in the coming years. The dune system of the Maharees, which protects the tombolo from storm surges and blowing sand deposits, has already retreated by more than 40m over the past decades. Increasing storm frequency and intensity and sea level rise will lead to the exacerbation of erosional pressures. The inhabitants of the Maharees Peninsula rely on a single access road, which has in the past frequently been blocked due to sand deposition. Without adequate adaptation efforts there is a risk for more frequent road interruptions. The cultural heritage of the Maharees notably includes a church and a graveyard which date back to the 13 th /14 th century. This heritage has been severely damaged during a storm event in 2012. Climate hazards such as coastal erosion and flooding put the conservation of this ecclesiastical site at risk. Growing tourism activities are an additional challenge. Especially during the summer months, a large number of short-term visitors is attracted by the opportunities for water recreational activities on the Maharees peninsula. Climate change increases the tourism potential through warmer summers. A historic lack of visitor management and tourist facilities (such as car parks) led to traffic congestion. The increasing number of people accessing the shoreline resulted in the degradation of the fragile dune ecosystem, and led to unease between the local community and visitors. The combined pressures from coastal erosion and tourism, exacerbated by climate change, present a serious threat to the livelihood and the ecosystems of the Maharees peninsula.

The measures implemented by the Maharees Conservation Association address the challenges encountered by the local community. In particular, they aim to: Preserve the ecosystem (restore the protective sand dunes, prevent wild camping, illegal parking, fire and waste dumping, control or restrict the access to vulnerable areas). Preserve the attractiveness of the area for sustainable tourism (prevent sand deposition that leads to the blockage of the only road to access the Peninsula, foster “regenerative tourism” to restore and enhance natural, social and economic capital, offer opportunities for visitors to be engaged in the preservation of the dune ecosystem, preserve the tangible and intangible cultural heritage). Foster a participatory governance to manage the coastal area in a sustainable way (build partnerships with local, regional and national stakeholders, promote bottom-up approaches to coastal restoration, design a community-led vision and a climate adaptation plan, raise awareness about the fragility of the dune ecosystems among locals and visitors).

In response to a lack of coordinated coastal management, the Maharees Conservation Association was founded by the local community in 2016. It involves a diverse range of stakeholders from hospitality business, tourism, farming, education and other sectors. Additionally, the association has built partnerships with local councils, national agencies, NGOs and research institutions. This has enabled the Maharees Conservation Association to address the increasing environmental and socio-economic pressures on the Maharees Peninsula, by implementing a number of community-led solutions, such as: · Dune fencing: Wind-blown sand deposition frequently blocked the access road to the Maharees Peninsula and this is expected to worsen with increasingly frequent and severe storms due to climate change. Thus, the Maharees Conservation Association installed dune fences along the base of the sand dunes with the help of local volunteers. The fencing has successfully prevented sand deposition, and the road has not been blocked after the intervention. In addition, the fences prevent human interference with the dune vegetation and thus protect the integrity of the dune system. However, the solutions require constant maintenance efforts as they have to be dug out or replaced. · Marram grass planting: Unmanaged access, parking, wild camping, fires and waste dumping led to significant dune degradation. The dunes were successfully restored through marram grass planting. Marram grass ( Ammophila arenaria ) is a plant with matted roots that naturally stabilises sand dunes. The restored dunes play a key role in increasing the resilience of the coastal area to climate change, acting as a barrier to storm surges, reducing flooding in the hinterland and mitigating coastal erosion. Since marram grass is a valuable habitat for other species, this nature-based solution has also contributed to enhance the biodiversity of the dunes. Wide participation from schools, locals and visitors in the marram planting ensured the successful implementation of the solution. Additionally, volunteers supported the continued maintenance activities multiple times each year. The environmental NGO Clean Coasts supported the restoration of the dunes through on-site training of community members. · Awareness raising and education: Diverse initiatives, such as community training events, education material, signage and guided walks, supported by the Kerry Education and Training Board , enable locals and visitors to learn about the unique natural heritage of the Maharees Peninsula. The Maharees Conservation Association also cooperates with Munster Technological University (MTU) lecturers and students to implement awareness raising events and educational activities on endangered plants and animal species and regenerative tourism. These educational initiatives aim to increase the understanding of the impacts of climate change and build awareness about the fragility and importance of the dune ecosystem. They favour behavioural shifts and increased involvement of the local community and visitors in biodiversity protection. In addition, this serves to build relationships between visitors and the local community and enhances the visitor experience of the destination. · Preservation of Cultural heritage: A range of actions has been taken to preserve the cultural heritage of the Maharees in the light of climate change and of rising tourism visit numbers. For raising awareness among visitors and locals, the Maharees heritage trail has been developed. The audio-guided tour, available as a smartphone app , allows to experience the rich natural and cultural heritage of the Maharees peninsula. In the summer months, the Maharees Conservation Association regularly organises a series of events related to natural and cultural heritage. Another initiative focused on documenting the traditional placenames , which revealed the close relationship between the community and its immediate environment. The built heritage is especially at risk from climate hazards. The research project SEA-CCHange , funded by the national government, focused on a historic graveyard and highlighted that coastal erosion and flooding will lead to further degradation of the site. Therefore, the association has successfully applied for the Adopt a Monument Programme organised by the Heritage Council. In the coming years, various actions are planned to preserve the Kilshannig Church and graveyard. It is also aimed to acquire funding for a full or partial reconstruction of the church gable which was damaged in 2012. · Visitor management: Without adequate management, the high number of visitors in the summer season had led to wild parking and congestion, with negative impacts on the local community and the Maharees dune ecosystem. This had been exacerbated by the lack of visitor facilities (such as parking areas). To address this challenge, a summer car park with access to the beach was established with support from the local authority and a local land owner. It was accompanied by marking, signposting, and a system to report illegal activities such as littering, illegal parking, camping or unauthorised access to protected areas. These activities contribute to protect the fragile dune ecosystem. · Research: The Maharees Conservation Association has built partnerships with universities, in particular with the University of Galway and the Munster Technological University (MTU). The collaboration with researchers provides the evidence base to implement effective solutions, and facilitates monitoring and evaluation. Drone images and measurements of erosion and accumulation demonstrate the progress in restoring the dune ecosystem. Surveys of residents and visitors have been carried out to increase understanding of the short- and long-term coastal evolution of the peninsula and to identify challenges and solutions. Moreover, a Coastal Erosion and Flood Risk Management Study, commissioned by the local authority (Kerry County), is nearing completion. It includes a medium to long-term prognosis for the tombolo and suggests a range of measures to protect it. The collaboration with research institutions has supported awareness raising through community and visitor engagement experiences.

The solutions implemented by the Maharees Conservation Association are cost-effective due to the extensive involvement of local volunteers and efficient use of a wide range of funding sources. Funding was primarily provided by the Kerry County Council and the National Parks and Wildlife Service (NPWS). Additionally, a wide range of other funding opportunities has been used (e.g., Creative Ireland, LEADER, BIM Flag, The Heritage Council, Local Authority Waters Programme, Clean Coasts an Taisce, Community Foundation of Ireland). Some solutions have also been supported through fundraising and private donations. The Climate Action Fund , provided by the Department of the Environment, Climate and Communications and administered by the local authority, now provides a systematic funding opportunity for coastal communities. The cost of implementing solutions varies. For example, chestnut fencing to support the recovery of marram grass and enhance the stability of the dunes costs €20 per meter. This solution has also been implemented to prevent sand deposition on the road. The Kerry County Council has provided a total of €14,000 for fencing over the last nine years. Some sections of fencing have also been funded by the Maharees Conservation Association and the National Parks and Wildlife Service. The installation of the fences as well as subsequent maintenance activities have been performed by unpaid local volunteers. This reduces costs, but requires constant commitment from the local community for maintenance. The implemented measures have led to various environmental, social and economic benefits. The restoration of degraded dunes improves the habitat conditions for protected species and contributes to decrease the vulnerability to erosional pressures. Regarding the social aspect, the involvement of schools, tourism businesses, visitors and residents improved the understanding of the challenges and built a shared responsibility for ecosystem protection. Increased environmental awareness led to behavioural change and decreased unease between residents and visitors. Through strengthening the resilience of the Maharees Peninsula and restoring the unique ecosystem, the initiative contributed to maintaining the attractiveness for tourism and recreational activities. In addition, new forms of tourism such as regenerative tourism and heritage tourism have been established. Sustainable tourism development therefore also secures income sources for the local economy.

Several factors were decisive for successfully initiating and implementing community-led approaches to coastal management on the Maharees Peninsula. The involvement of local stakeholders from diverse backgrounds, ranging from tourism, the hospitality business, farming and education, ensured the representation of different economic and social interests. Strong social cohesion between different members of the community was fostered though the planning of and participation in activities such as fencing or marram grass planting. The support of the local community is a key success factor, as it allows for a higher flexibility in responding to urgent challenges outside the standard working hours. Moreover, the local knowledge of the stakeholders enables to monitor the solution effectively. Building trustful partnerships with public authorities (e.g. Kerry County Council, National Parks and Wildlife Service) formed the basis for pilot testing of innovative solutions. These partnerships provided access to technical and financial support and helped to align climate change adaptation initiatives with broader policy objectives, such as biodiversity protection and sustainable tourism. The evidence base for the implementation of several solutions was built through the collaboration with universities. The challenges for the Maharees Peninsula were effectively addressed through nature-based solutions. Additionally, awareness-raising (e.g. guided tours, educational material, social media) resulted in significant behavioural change among visitors and locals. A recent collaboration with the Dingle Hub and Creative Ireland called Neart na Machairí supported community-led climate adaptation planning through creativity. The Maharees Conservation Association is also actively engaged in exchanging knowledge and experiences with other coastal communities, e.g., by presenting the learnings at conferences, fostering public outreach, and directly engaging with other coastal communities at site visits, thus facilitating replication. By 2025, 25 coastal communities in Ireland were engaged in this process. However, the efforts to build coastal resilience are hindered by the lack of a holistic coastal management instrument and insufficient systematic support of community-led initiatives from higher governance levels. The management of the Irish coast remains fragmented, with numerous departments and public bodies having a remit in the coastal area. This results in conflicting policy objectives and gaps in the coherence between local, regional and national governance levels. In addition, the Maharees Conservation Association initiative relies heavily on the commitment of local volunteers and external funding sources. Strengthening long-term resilience of the Maharees Peninsula would benefit from a more formal recognition of community-led initiatives, adequate resourcing, and the creation of mechanisms and forums that facilitate the exchange of technical and policy knowledge to support inclusive and informed decision-making.
