Primary Economic Activities (Leaving Cert Geography): Revision Notes
Primary Economic Activities
The Greater Dublin Area demonstrates a unique pattern in primary economic activities compared to western regions of Ireland. Whilst employment in primary sectors remains relatively low, the productivity and specialisation levels are remarkably high due to several advantageous conditions.
Agriculture
Overview and characteristics
Agriculture in the GDA employs only 3% of the regional population, which is significantly lower than in western Ireland. However, this small workforce achieves exceptional results through highly productive and specialised farming methods.
Specialised agriculture involves focusing on a single crop type (such as wheat) or single animal species (such as cattle) to maximise efficiency and expertise.
The region's agricultural sector generates incomes that are 40% higher than the national average. This success stems from the commercial and intensive nature of farming operations, which prioritise high yields and maximum output. Unlike traditional mixed farming found in western regions, GDA agriculture focuses on market-oriented production designed to meet urban demand.
The region contains approximately 50% of Ireland's total greenhouse facilities, creating a thriving market gardening sector, particularly around Lusk in North County Dublin. This concentration reflects the area's suitability for intensive horticultural production.
Factors affecting agriculture in the GDA
Four key factors work together to create ideal conditions for agricultural development in the region:
Climate advantages
The GDA benefits from a temperate climate that strongly supports agricultural productivity. Summer temperatures average 16°C, providing warmer conditions than western regions. Additionally, the area receives nearly two hours more sunshine daily compared to western counties.
These climatic conditions enable successful arable farming, including the cultivation of wheat, barley and oats. Remarkably, 15% of Ireland's total wheat production occurs within the GDA. The extended growing season of 280 days proves particularly beneficial for market gardening and potato cultivation.
Potato blight is a fungal disease that causes potatoes to rot, but the GDA's drier climate reduces this risk compared to western regions.
The region produces 20% of Ireland's national potato crop, benefiting from the proximity to the Irish Sea, which moderates temperatures and reduces the risk of severe frost damage to sensitive crops like salads, flowers and root vegetables.
Relief and accessibility
The GDA's predominantly lowland relief creates exceptional conditions for modern agriculture. This flat terrain allows easy access for heavy machinery, enabling high levels of mechanisation throughout the region. Consequently, all available land can be intensively farmed without the limitations imposed by steep slopes or difficult terrain.
The lowland character means the region remains unexposed to harsh weather conditions, maintaining warmer soil temperatures that promote plant growth. Additionally, the flat landscape reduces soil erosion from wind and rainfall, preserving the fertility of agricultural land.
The main exceptions to this lowland pattern are the Dublin and Wicklow Mountains, where the terrain proves unsuitable for intensive agriculture. These upland areas are instead utilised for sheep rearing and forestry operations.
Soil quality
The region's highly fertile brown earth soils provide an excellent foundation for intensive crop production. These soils possess several advantageous characteristics that support agricultural productivity.
The brown earth soils are stone-free and easily worked, reducing labour intensity and allowing efficient mechanisation. Their calcium-rich composition produces nutrient-rich grasses that promote healthy bone growth in grazing animals. This soil quality contributes significantly to the success of horse breeding operations in County Kildare.
The fertile nature of these soils allows continuous intensive farming of arable crops without depleting the land's productivity, supporting the region's commercial agricultural focus.
Market access and opportunities
The presence of Dublin City provides the GDA with exceptional access to Ireland's largest urban market. The capital's population of 1.2 million people creates substantial demand for both basic foodstuffs and specialised agricultural products.
Market-oriented farms focus on producing crops that are in high demand from local markets rather than following traditional farming patterns.
The region's higher standard of living generates increased disposable income, creating demand for premium and specialised food products. Well-developed transport infrastructure connecting the GDA to Dublin City significantly reduces transportation costs compared to rural areas.
The commercial nature of farming in the region helps address common rural problems. Farmers tend to be younger than the national average (37 years old) and are highly educated in both agricultural techniques and business management. They adopt scientific, market-oriented approaches to farming that maximise profitability.
Farm sizes in the GDA remain much larger than western equivalents, averaging 42 hectares compared to smaller western holdings. This scale allows for more efficient operations and greater investment in modern technology.
Food Processing Example: Tayto and Guinness
Food processing operates on a much larger scale than in western regions. Major companies like Largo Foods purchase 10% of the national potato crop for Tayto crisp production, while Guinness sources wheat and barley from local suppliers for their Dublin manufacturing plants.
Satellite towns are settlements that developed near but independently from larger urban areas. They typically maintain their own markets and services while benefiting from proximity to major cities.
Several satellite towns that expanded during periods of economic growth provide additional substantial markets for agricultural produce, creating multiple outlets for regional farmers.
Forestry
Forestry plays a very limited role in the GDA's primary sector due to the high productivity of agricultural land for farming purposes. The majority of available land generates greater economic returns through agricultural use rather than forest production.
Forest coverage in the region is mainly restricted to the Dublin and Wicklow Mountains, where the terrain proves unsuitable for intensive agriculture. The acidic peat soils and mountainous relief create conditions better suited to forestry than farming.
The region's mild winter conditions promote the growth of coniferous forests. However, many of these forested areas serve recreational purposes as parks rather than commercial timber production. This reflects the region's proximity to Dublin's large urban population, which values forests for leisure activities and environmental benefits.
Fishing
Fishing represents a declining primary activity in the GDA, demonstrating significant changes over recent decades. This sector was once considerably more important to the regional economy but has faced numerous challenges that have reduced its contribution.
Historical decline
The fishing industry has experienced dramatic decline since the 1960s. In 1960, the GDA accounted for 35% of Ireland's total fish catch, but this figure has fallen to just 2% today. This represents one of the most significant sectoral changes in the region's economic development.
Howth serves as the GDA's largest fishing port and ranks as the sixth largest in Ireland nationally. However, even this major facility has struggled to maintain its historical importance in the face of various challenges.
Challenges facing the fishing industry
Several interconnected factors have contributed to the decline of fishing in the GDA:
Major Challenges to GDA Fishing:
- Overfishing: Rapid decline in fish stocks resulted primarily from overfishing during previous decades, making sustainable fishing increasingly difficult
- EU Restrictions: European Union intervention introduced fishing quotas, seasons and conservation areas to protect remaining fish stocks
- Competition: Upgrades to western seaports created increased competition, with western regions developing aquaculture (fish farming) as an alternative
Environmental challenges
The Irish Sea faces significant pollution challenges that affect fishing productivity. The sea has been contaminated by nuclear waste disposal from the Sellafield nuclear power plant in northwest England since the 1950s, making it one of the world's most radioactive seas.
This pollution particularly impacts shellfish farming, which affects the Dublin Bay area significantly. The bay produces 40% of Ireland's exported prawns, making pollution a major concern for this specialised sector.
Fish farming in the Irish Sea proves less productive than in cleaner Atlantic waters, further limiting the industry's potential for recovery and growth.
Key Points to Remember:
-
Agriculture dominates the GDA's primary sector with only 3% employment but 40% higher productivity than the national average through specialised, intensive farming
-
Four key factors support agricultural success: favourable climate (16°C summers, longer growing season), lowland relief (accessible to machinery), fertile brown earth soils (stone-free, calcium-rich), and excellent market access (Dublin proximity)
-
Commercial focus characterises GDA farming with younger, educated farmers (average age 37 years), larger farm sizes (42 hectares), and major food processing companies like Tayto and Guinness
-
Forestry remains limited due to highly productive agricultural land, mainly restricted to Dublin and Wicklow Mountains for recreational rather than commercial use
-
Fishing has declined dramatically from 35% of national catch in 1960 to just 2% today due to overfishing, EU quotas, competition from western ports, and Irish Sea pollution from nuclear waste
