GIS Monthly Maps 2024

The Teagasc spatial analysis unit use data from a number of sources to assist farming. The sources used include the Ordnance Survey of Ireland, the Central Statistics Office, and Earth observation satellites, and remote sensing technologies. 

In creating the 'Map of the Month' the unit takes the most interesting map produced in each month to present it to a wider audience to promote discussion and debate  on the contribution of spatial analysis to Irish agriculture and food and on the specific maps produced. Maps can be viewed in interactive and pdf format. Read more about map of the month here.

Farms and Waterbodies


December - Farms and Waterbodies

Cartographers:  Dr Stuart Green

View map here: Farms and Waterbodies

Farms in Ireland are very fragmented, this can lead to problems for farmers and policy makers. An example is shown here: looking at how farms break down across waterbodies.

We have mapped all the subcatchments in the Republic and calculated what percentage of the farmers present in each subcatchment only farm in that subcatchment - to put it crudely, this would mean that their farming activity would only impact that particular subcatchment. However, on average only 46% of farmers in each subcatchment farm only there. The majority farm in at least two subcatchments, and sometimes even across more that two.   

Where is Teagasc? 


November - Where is Teagasc? 

Cartographers:  Dr Stuart Green & Dr Jesko Zimmermann

View map here: Where is Teagasc? Or more precisely, where is our office?

The concept of location can be surprisingly ambiguous. In this map we go down an unexpected rabbit hole trying to answer a seemingly simple question: Where do we work?

 

The Bioeconomy Ireland Week map series 


October - The Bioeconomy Ireland Week map series 

Cartographers:  Dr Jesko Zimmermann

As part of the Bioeconomy Week Ireland 2024, Teagasc has been producing a series of maps to support specific events and the Week as a whole. This year we produced three maps:

The Bioeconomy Ireland Week 2024 - Events near me - Here we provided an overview of the events held as part oif this years Bioeconomy Ireland Week

The National Library Campaign 2024 - The Marine Institute organised a series of events, including workshops and talks as part of the Bioeconomy Ireland Week, for which we provided an overview.  

Examples from the LEADER programme - In collaboration with Munster Technological University, we provided examples for bioeconomy related projects from the LEADER programme. 

 

 

Grasslands managed as Paddocks


September - Grasslands managed as Paddocks

Cartographers:  Dr Stuart Green

View map here: Grassland managed as paddocks

In July 2022, we published a new method to detect if fields were being managed as paddocks (O'Hara et al., 2022). The method used satellite imagery timeseries to show the presence of paddocks field by field. It's important to know where paddocks are to show the location of intensively managed grasslands, as these play an important role in greenhouse gas emissions and water quality. In the paper we tested the method only in one pilot area (the Barrow catchment) but have since repeated the process for the whole country. 

Here we present the resulting national map in a simplified form. We use a grid of 1km squares across the whole country and calculate the percentage of enclosed grasslands that are managed as paddocks. Note that Dublin is excluded, as are uplands and areas with no enclosed grasslands. 

An example of a Signpost Farm habitat map


August - An example of a Signpost Farm habitat map

Cartographers:  Dr Stuart Green

View map here: An example of a Signpost Farm habitat map

As part of the Teagasc Signpost Programme, participating farms are mapped for habitats using drone imagery. These maps are intended to form a baseline to observe change and as a platform for discussion between farmers and advisors. All 120 farms are mapped. 

Farm/Soil Complexity


July - Farm/Soil Complexity

Cartographers:  Dr Stuart Green

View map here: Farm/Soil Complexity

National soil maps such as Teagasc's Irish Forest Soils (IFS) indicative map are not the correct scale to be used at field scale - you cannot reliably say that if a field lies within a soil type polygon, the soil in the field is that soil type. This is due to the scale of a map determining the smallest object that can be detected, and the scale of national soil maps is grater than the scale we need to map fields. We can, however,  map broad geographies and use the IFS map to identify areas where there are lots of soil types (complex soil geographies) and where there there are fewer soil types (simple soil geographies). 

Here we present a measure o farm scale soil complexity - we map the length of soil boundaries in a farm divided by the size of the farm (excluding upland farms as these tend to include large unenclosed areas). It shows an interesting geography; those farms in pale are generally larger farms with low soil complexity. They correlate well to areas of the country with farms in dairy and tillage. In darker areas farms have a high complexity per hectare and we see these particularly in Monaghan and Clare. 

 

 

 

Sharing the land: Commonage in Ireland


June - Sharing the land: Commonage in Ireland

Cartographers:  Dr Jesko Zimmermann

View map here: Sharing the land: Commonage in Ireland

In this month's map we look at commonage in 2022

Commonage farming is one of the defining features of Irish upland agriculture. In its most general, the term commonage describes land owned or used by more than one person. Legally, the situation is more complex, and a more detailed breakdown of what circumstances can be regarded as commonage can be found at https://legalblog.ie/commonage/. Commonage is generally associated with upland sheep grazing and turbary rights (i.e. the cutting of turf in bogs), though one of the oldest and most-well known commonage areas is the Curragh in Co. Kildare which is a flat grass plain of nearly 2,000 ha, and, while grazed by sheep, is commonly associated with horse breeding and training. Commonage has been a part of the Irish farming landscape throughout history, and like all agriculture has transformed as circumstances and requirements changed. A good overview of the history of commonage can be found http://www.yourcommonage.ie/p/commonage_3.html.

 

Changes in claimed farming area between 2017 and 2021


May - Changes in claimed farming area between 2017 and 2021

Cartographers:  Dr Jesko Zimmermann

View map here: Changes in claimed farming area between 2017 and 2021

In this month's map we look at the recently published public cut of the LPIS data to show aspects of farming dynamics. 

Farming systems are inherently dynamic, with farmers constantly adapting to internal and external drivers, both long and short term. One manifestation of this dynamic is change in farmed area. The Department of Agriculture, Food and the Marine recently released a public version of the Land Parcel Identification System (LPIS), a database containing the outlines and cropping information for all fields for which subsidies are claimed. In these maps we are showing changes in the total area claimed by farmers, averaged by EDs, in the years 2017 and 2021. EDs with less than five farms reported where obscured for privacy reasons. The map on the left shows the total range of claimed area in the timeframe (i.e. the difference between the largest and the smallest claimed area). This value gives an indication of the overall dynamics of the farms in an ED. To account for differences in farm size, the area was normalised by size in 2021. The map shows three distinct areas. (1) A North East to South band presents the largest range of sizes between years, representing an area linked to larger farms with more intensive agriculture. (2) A Mid North to South West band generally shows small changes in claimed land, these areas are dominated by less intensive beef farming. (3) The North West shows both large and small changes. Generally, these areas are least intense, however, while commonage areas were removed for the analysis, the area is dominated by large open pastures, so single changes in area claimed can have large impacts on the average change in the ED. The right map shows the direction of change (with any change over 0.1 ha being considered significant). Generally the distribution of increase and decrease is evenly distributed across Ireland. The reason for changes are diverse, but include changes in landownership and rentals, changes in exclusion criteria, temporarily changes in use to non-agricultural, and permanent removal of land from agriculture (e.g. to forestry or built area)

 


April - Hedgerow carbon of County Kildare

Cartographers:  Dr Stuart Green

View map here: Hedgerow carbon of County Kildare

This month we take an existing national data set and use spatial analysis to add value to it.

The Tailte Éireann National Land Cover Map (2018) digitises the footprint of all the hedgerows in the country. The recent Farm-Carbon Report from the EPA on research work done in Teagasc gives us data on the amount of carbon stored ,per ha, in typical hedgerows. The report breaks down hedgerows into two basic types (once mature)- regular, tightly cut annually and irregular, less tightly cut and “bushier”. The amount of carbon stored per Ha is not too dissimilar but the amount of carbon stored by length is much higher for the irregular.

Importantly the biodiversity value of irregular hedgerows is much higher than regular.

The NLC map doesn’t not distinguish between hedges in this way, so we have developed a way to characterise the hedgerow based on the shape of its footprint. We use spatial analytical methods to breakdown the hedgerow area in the NLC into individual hedgerows and then characterise as irregular and regular. We also label the hedgerow as internal to the farm, external boundary of the farm or a hedgerow shared between two farmers.

In the map we present the map for County Kildare with the total above ground carbon stored in the hedgerows for both types:

and the distribution of types across the three different boundary classes: 

 

The bar chart shows that “good fences make good neighbours” as large irregualr hedges are 3 times more common than regular hedgerows.

 


March - Apple Research in Teagasc

Cartographers:  Dr Stuart Green

View map here: Apple Research in Teagasc

In this month’s T-Research magazine, current research into apple breeding is highlighted. Teagasc has a long history in apples and used to have a dedicated Pomology Centre in Waterford. This was a legacy of Teagasc predecessor organisation An Foras Taluntais.

Here we present a scan of a paper soil map of the old centre. The centre was sold in the 1980s but we can see a clip from the RTE archive showing research at the centre focusing on a then new variety; Jonagold.

 


February - The LUCAS 2022 Land Cover Survey 

Cartographers:  Dr Stuart Green

View map here: The LUCAS 2022 Land Cover Survey

The Land Use/Cover Area frame Survey (LUCAS) is a pan-european ground survey of land cover across the EU. Performed every 3 years it involves surveyors visiting thousands of points across Europe (more than 8000 in Ireland alone). Detailed records (including photographs) are made of land cover, land use and, in a sub-set of points, soil information. Here we simply map landcover at the highest level of detail recorded (the numbers on brackets are the number of points with that land cover recorded out of 8597 points).


January - The Soil Water Index

Cartographers:  Dr Jesko Zimmermann

View map here: The Soil Water Index

The  Copernicus Global Land Service  is a fantastic resource of global earth observation products. It is part of the European Land Monitoring Core Service and provides a range of derived products covering areas of Vegetation, Energy, Water and the Cryosphere but also hot-spot monitoring.

In this map we showcase the Soil Water Index, which is built from radar satellite imagery and provides a good indication of the soil water status, including an estimate of deeper soil layers. 


About Map of the Month

In addition to undertaking geographical analyses and producing maps for research projects, the spatial analysis lab responds to ad hoc requests for contributions.  The latter may be for in-house purposes or to inform policy submissions. While dissemination is a key objective of research projects, maps produced in response to such requests rarely get a wider audience. We’ve decided that we’ll take the most interesting map we have produced in each month and to present it here to hopefully find a wider audience and promote discussion and debate on both the contribution of spatial analysis to Irish agriculture and food and on the specific maps produced.

Whilst this map can be shared please check with us before reproducing it in a publication. Many of the data sets we use are under licence with conditions attached.
