CORINE Landcover 2024

 

The Environmental Protection Agency (EPA) has produced the latest CORINE (Co-ORdinated INformation on the Environment) landcover data series (CLC) for Ireland for the reference year 2024. This is the sixth instalment of CLC since the first data was produced for refence year 1990 and the EPA has been responsible for delivering the CLC dataset in Ireland since CORINE 2000.

CLC 2024

The CORINE 2024 project for Ireland includes the following three datasets as its deliverables:  

  1. A revised 25ha CORINE 2018 dataset (CLC 2018_revised)
  2. The 2018 - 2024 5ha Change dataset (CLCCh 2018-2024)
  3. The Updated CLC 2024 25 ha dataset (CLC 2024)

All three datasets are now available to view and download from the EPA’s Geoportal at https://gis.epa.ie

The CORINE timeseries is part of the Copernicus Land Monitoring Service (CLMS). Corine and other pan European land monitoring data can also be accessed at  https://land.copernicus.eu/en

The CORINE data for Ireland was produced with funding from the European Commission. Data for the project was provided by Copernicus, Coillte and the Department of Agriculture, Food and the Marine (DAFM).

The CORINE Landcover (CLC) nomenclature guidelines, including class definitions, can be found at Home :: Corine Land Cover classes  

 

 

CORINE 2024 - Results

The full national statistics from the CORINE 2024 25ha landcover status dataset for Ireland at Level 1 are given below in table 1 and at level 3 in table 2.

The data shows that agriculture continues to be the dominant landcover type present in Ireland, covering 4.7 million hectares or 67.13% of the country. This is a slight reduction from 67.33% in CORINE 2018, followed by Wetlands at 14.7%, forest and semi-natural areas at 13.54%, Artificial at 2.51% and Water which covers 2.1%*.

Fig. 1 below shows the percentage cover of the five level 1 landcover classes in Ireland. 

* Not including class 523 Sea and Ocean.

CORINE 2024 - Level 3 results

Looking at the individual level 3 classes, class 231 Pastures is the most dominant landcover type at 3,864,853.20 ha (54.62%); followed by class 412 Peatlands at 96,993.98 hectares (13.58%); and class 243 Land principally occupied by agriculture, with significant areas of natural vegetation at 488,186.53 ha (6.9%). The hierarchy of landcover classes at Level 3 is shown in fig. 2 below for the top ten classes. The full data is given in table 2.

CLC Change 2018 -2024

The 2018 - 2024 5ha Change dataset (CLCCh 2018-2024), maps all landcover change in Ireland greater than 5 hectares between the reference years 2018 and 2024. Looking at this data gives greater detail on landcover dynamics in Ireland than from just looking at the 25ha status layers alone. The full change statistics are available to view and download from table 3 below. The dominant change types are also illustrated in fig. 3 below.

Key landcover change trends 2018 - 2024

  • Overall there was 273,933 ha of change in Ireland between 2018 and 2024. This represents 3.87% of the total national area (ROI). This is an increase of 26,622 ha or 0.37% of the national area compared with the previous CORINE reporting period of 2012 -2018.
  • Change and rotation within the agriculture and forestry classes remains the dominant landcover change type, accounting for 96% of all change by area. 
  • The largest individual change type was the conversion of 77,218 ha of land from class 231 Pasture to 211 Arable land, representing 28% of all change. This is an increase of 23,107 ha or 42% in this change type compared to the previous reporting period (2012-2018).
  • There has been a corresponding decrease in the amount of 211 Arable converted to 231 Pasture in the same period. This type of change has fallen from 58,248 ha in 202-2018 to 40,073ha in 2018-2024, a drop of 18% in the rate of this change type.
  • 4,389 ha of land was converted into forestry (afforestation), primarily from agricultural land. This is a 28% increase in afforestation since the last reporting period.
  • There was a 40% increase in the rate of forestry maturing from transitional forestry (class 324) to the mature forestry classes (312, 313 or 311). There was also a 6.6% increase in the rate of clearfelling.
  • There was a 127% (3,167 ha) increase in the rate of non-artificial land converted to an Artificial surface class. This is the largest increase in rate of change since 2018 at Level 1. 39% of this was in the development of new construction sites (class 133).
  • 62 % new land converted to an artificial surface came from the 231 Pasture class (3,515 ha).
  • For the first time, areas of land above 5ha which were converted to 'solar farms' were mapped in CORINE. In total, 751 ha (0.01% of national area) of land was converted to class 121 Industrial or commercial units which incorporates solar farms or parks.  This includes 407 ha of class 211 arable land and 344 ha of class 231 Pastures.
  • 37 instances of new solar farms in total were identified. The largest of which was 151 ha of agricultural land in Co. Cork, see image below.
