East Cork, Waterford, Galway and the Shannon Estuary will be the first to bear the brunt of an “alarming and startling” rise in sea levels, a TD has warned.

As the Irish Examiner reports, David Stanton (Cork East) expressed his fears of a “truly frightening” outcome for many coastal communities in the continued absence of a national coastal risk strategy.

“There is no point waiting until the seawater is up to our knees and then saying we should have planned for this 20 years ago,” he said.

Discovery of the remains of a “drowned” prehistoric house in north Connemara may be further evidence of sea-level rise along the Atlantic coast in the last millennium.

As The Sunday Times reports today, parts of a small prehistoric dwelling covered by sea except at low spring tide have been identified by archaeologist Michael Gibbons and engineer Shane Joyce on the coast south-west of Clifden, Co Galway.

The site is in a sheltered “lagoon-like setting” on the tip of the Faul peninsula, at the junction of Clifden and Ardbear bays.

Gibbons said that the structure is similar in size to early Neolithic houses, and it is protected from tidal surges by Oileán Gearr or Islandagar, a small island on its western side.

Gibbons said it was further evidence of a “drowned prehistoric landscape”, which has been researched and dated by NUI Galway palaeoecologists Prof Michael O’Connell and Dr Karen Molloy.

O’Connell and Molloy have estimated that sea levels rose by as much as four metres on the Atlantic coast in later prehistory - as in 1,000 years ago – with Galway Bay being younger than originally estimated.

Prof O’Connell said that it was “quite reasonable” to suggest the structure identified by Gibbons and Joyce may be early Neolithic, given that sea level rise occurred in the late Neolithic period.

O’Connell and Molloy’s work focused on tree stumps, believed to be bog pine, which have been exposed at low tide by storms dating back to 2010, along with pollen analysis of coastal peat deposits.

Gibbons said that a shell midden dating from 4,000 BC on the Errislannan peninsula, just south-west of the Faul location, was also evidence of Neolithic settlement by early farmers.

Dublin Bay’s sea level seems to be rising faster than forecast — and at twice the global average over the past two decades.

The Irish Times reports on this startling claim from Dun Laoghaire-Rathdown County Council’s (DLRCoCo) climate change action plan, which also notes that weather extremes are “likely to increase in their frequency and intensity”.

The report comes following one of Ireland’s hottest summers on record, itself just months after a first ever Status Red warning for snow was issued by Met Éireann.

Three Dublin local authorities launched their climate action plans on Monday (9 September), with DLRCoCo’s plan pledging to “prioritise nature-based flood defences where possible” over the next five years.

Marine Leisure & Aquatic Tourism

Domestic coastal tourism expenditure was approximately €698 million in 2018, while domestic marine tourism generated €381 million.

Activities such as walking/ running along the coast, swimming and beach visitations are among the most popular activities for domestic visitors on both day and overnight trips.

While participation rates in pursuits such as bird and wildlife watching in coastal areas and visiting nature reserves, etc. in coastal areas were lower, these activities did see the highest frequency of both day and overnight trips for those active in these activities. 

According to the National University of Galway (NUIG) research the average expenditure per coastal day trip in 2018 was calculated at €95. The equivalent for coastal overnight trips was €310. The estimated water-based activity expenditure per person per trip across the sample was €56 rising to €73 for the subsample that actually undertake waterbased activities on their coastal visits. The results also indicate that domestic tourists undertake the majority of their marine activities on the West and South coasts of Ireland and that there are notable differences in participation rates across age groupings, social classes and by family makeup.

A domestic tourist is defined in this report as a person who spends at least one night away from home on their trip. Total expenditure by domestic tourists in coastal areas was estimated to be €698 million in 2018, which represents 35% of the total expenditure by domestic tourists (using the broader Fáilte Ireland measure for domestic tourists that includes business trips equating to 10.92 million in total trips and €2,006 million in total revenue).

The marine-related activity expenditure, or what might truly be referred to as domestic marine tourism, is estimated to generate revenue of €381 million with €172 million being spent on water-based activities. Marine tourism makes up an estimated 19% of total domestic tourism expenditure.

Marine Leisure Tourism - FAQ

Coastal tourism refers to land-based and water-based tourism activities taking place on the coast for which the proximity to the sea is a condition including also their respective services. Coastal and Marine Tourism & Leisure are seen as one of the Blue Economy (BE) sectors that can help unlock the potential of multi-use of space at sea by engaging with Blue Growth (BG) sectors such as Aquaculture and Marine Renewable Energy among others.

NUI Galway carried out a survey of domestic residents in Ireland in 2019 as part of a survey entitled "Valuing and understanding the dynamics of Ireland's Ocean Economy". The purpose of the household survey was to profile the domestic market for single-day trips (leisure) and overnight trips (tourism) for coastal and marine-related activities in Ireland. The results of the survey are also used to estimate what proportion of an Irish resident's total domestic tourism expenditure is in coastal areas (coastal tourism) and what proportion is spent on undertaking marine-related activities (marine tourism).

The NUI results highlight the important contribution that Ireland's marine and coastal resources make to the leisure experiences of the general population and the importance of the domestic tourism market to local coastal economies. The analysis indicates that domestic coastal tourism expenditure was approximately €698 million in 2018, while domestic marine tourism generated €381 million. Activities such as walking/ running along the coast, swimming and beach visitations are among the most popular activities for domestic visitors on both day and overnight trips. While participation rates in pursuits such as bird and wildlife watching in coastal areas and visiting nature reserves, etc. in coastal areas were lower, these activities did see the highest frequency of both day and overnight trips for those active in these activities. Satisfaction with the available marine-related leisure facilities was also found to be very high across all activities.
