CONTENTS
Introduction
Ireland is an island on the western fringe of Europe between
latitude 51 1/2 and 55 1/2 degrees north, and longitude 5 1/2 to
10 1/2 degrees west. Its greatest length, from Malin Head in the
north to Mizen Head in the south, is 486 km and its greatest
width from east to west is approximately 275 km. Since 1921 the
island has been divided politically into two parts. The
independent twenty-six county area, comprising 70,282 sq. km, has
a population of 3,523,401 (1991). Northern Ireland, which is part
of the United Kingdom and contains six of the nine counties of
the ancient province of Ulster, has a population of 1,569,971
(1991). In 1973 Ireland became a member of the European Union
(EU).
Physical Landscape
The two great mountain systems of Europe, north of the Alps,
converge westwards to meet and mingle in Ireland. The older
(Caledonian) extends from Scandinavia through Scotland to the
north and west of Ireland, where it gives rise to the rugged and
mountainous landscapes of Counties Donegal, Mayo and Galway. The
higher mountains are of quartzite which weathers into bare,
cone-shaped peaks such as Errigal (752 m) in Donegal, Croagh
Patrick (765m) in Mayo and the Twelve Bens in Galway. Structures
of similar age are responsible for the Wicklow and Blackstairs
mountains which extend south-westwards from Dublin Bay for a
distance of more than 100 km. In these, long-continued denudation
of a great anticlinal structure has exposed a granite core which
now forms rounded peat-covered uplands, the crests being notched
in places by glacial cirques. The mountains are penetrated by
deep glacially modified valleys of which the best known is
Glendalough in County Wicklow.
The younger structures (Armorican) extend from central Europe
through Brittany to southern Ireland, where they reappear as a
series of east-west anticlinal sandstone ridges separated by
limestone or shale-floored valleys. The hills rise in height
westwards culminating in Carrantouhill (1041 m) in the
Magillycuddy Reeks, the highest mountain in the country. The
famous Upper Lake of Killarney nestles in the eastern slopes of
this range. The valleys separating the western extension of these
mountains have been flooded by the sea, giving rise to a number
of long deep inlets.
In north-eastern Ireland basaltic lavas spread widely over the
existing rocks in Eocene times and now form the bleak plateau of
east Antrim. Westwards the basalt is downwarped and the resultant
drift-covered lowland is occupied in part by Lough Neagh, the
largest lake in Ireland.
The heart of the country is a limestone- floored lowland bounded
on the south by the Armorican ridges and on the north and west by
the Caledonian mountains. This lowland is open to the Irish Sea
for a distance of 90 km between the Wicklow Mountains and the
Carlingford peninsula, giving easy access to the country from the
east. It also extends westwards to reach the Atlantic Ocean along
the Shannon Estuary, in Galway Bay, in Clew Bay and again in
Donegal Bay. Numerous hills break the monotony of the lowland
which rises westward towards the coast in County Clare where it
terminates in the cliffs of Moher, one of the finest lines of
cliff scenery in Western Europe.
Much of Ireland was covered by ice during the Pleistocene period.
This ice finally melted away about twelve thousand years ago,
leaving behind evidence of its former presence in most of the
minor physical features of the landscape. Throughout the greater
part of the lowland the bedrock is hidden by glacial deposits
which, in the north central part of the country, form a broad
belt of small hills (drumlins). The glacial cover also modified
the early drainage pattern and in places created groundwater
conditions which facilitated the growth of peat bogs.
Rivers
The lowland is drained by numerous slow- flowing streams, the
largest of which is the River Shannon, 340 km in length. In its
middle course this river broadens into a number of attractive
lakes but as it approaches the sea its gradient steepens. This is
the location of Ireland's earliest hydro-electric power scheme.
The main rivers draining eastwards are the Lagan, which flows
into Belfast Lough, the Liffey, with Dublin at its mouth, and the
Slaney, which enters the sea at Wexford. In the south of Ireland
the long east-west synclinal valleys are occupied by such rivers
as the Suir, the Lee and the Blackwater which reach the coast by
making right-angled turns to pass southwards through the
sandstone ridges in narrow gorge-like valleys.
Climate
Ireland's mild and equable climate is a reflection of the fact
that its shores are bathed by the relatively warm ocean waters of
the North Atlantic Drift. Valencia, in the extreme south-west,
has an average January temperature of 7¡C and a July temperature
of 1 5¡C, a range of only eight degrees. The figures for Dublin
are 4.5¡C in January and 1 5.5¡C in July, a range of eleven
degrees. Extremely high or low temperatures are virtually
unknown.
Influenced by the Atlantic Ocean the weather in Ireland is mild, wet and changeable. It is not too hot and not too cold. Summer temperatures over 30°C (86 °F) are rare enough occurrences (perhaps once or twice a decade). The average monthly temperature in Ireland are:
January (5°C = 41°F), February (5°C = 41°F), March (7°C = 45°F), April (8°C = 46°F), May (11°C = 52°F), June (14°C = 56°F), July (16°C = 60°F), August, (16°C = 60°F), September (14°C = 56°F), October (11°C = 51°F), November (8°C = 48°F), December (7°C = 44°F). It can rain at any time in Ireland but prolonged periods of rainfall are rare enough. Snow and severe frost are usually confined to December, January and February.
Rainfall is heaviest on the westward facing slopes of the hills
where it may exceed 3,000 mm in Kerry, Mayo and Donegal. The east
is much drier and Dublin records on average only 785 mm annually.
The outstanding feature of the Irish weather is its
changeability, a characteristic which it shares with all the
countries that lie in the path of the temperate depressions.
However more stable atmospheric conditions may arise in winter
with the extension of the continental high pressure system
bringing clear skies and cool conditions, especially to the
eastern part of the country. In summer an extension of the Azores
high pressure system may bring periods of light easterly winds
and bright sunny weather.
Soils
Most of the soils of Ireland are derived from glacial drift and
reflect its varied composition and texture. There are large areas
of fertile grey-brown podzolic soils on the better drained parts
of the lowland. These give way to less fertile acid brown earths
where the parent material is low in lime or to gleyed soils where
the drainage is poor. Thin acid peaty soils are widespread on the
hills.
Vegetation
The visitor to Ireland is immediately impressed by two aspects of
the vegetation cover. The first is an impression of intense
greenness, the result of the abundant grasses responding to the
mild moist air. The second is the relative absence of trees,
especially along the western seaboard where strong winds are the
main limiting factor to growth. The once extensive oak woodlands
of the midlands were cleared over most of the country by the
seventeenth century and remain today only as remnants in remote
areas. The flora is of more limited variety than elsewhere in
Europe but it has some interesting features. In the extreme
south- west (Cork/Kerry) there is a vegetation with Mediterranean
affinities which includes the Arbutus. The numerous bryophytes
and lichens reflect the mildness and high humidity of this part
of Ireland. In the Burren in County Clare an Arctic-Alpine flora
survives from a colder period in the past.
Fauna
Apart from seals which breed around the coast and whales which
occasionally visit coastal waters, Ireland has twenty-seven
species of mammal. These include the red deer, pine marten,
badger, otter, hare and stoat which are native to the country, as
well as introduced species such as the fallow deer, rabbit and
other rodents. Ireland's only reptile is a small lizard and there
are three amphibia, the newt, the frog and the toad. The rivers
and lakes have salmon, trout, char, pollan, perch, pike and eels.
Of the three hundred and eighty species of wild bird recorded in
Ireland, only about one-third breed in the country.
People
Ireland has been inhabited since Stone-Age times and for more
than five thousand years has been the recipient of peoples moving
westwards across the European continent. Each new group of
immigrants has contributed something to its population and
culture and no group ever entirely obliterated the character of
the earlier ones. It is these diverse elements that have come
together to form the distinctive Irish nation of today.
The population of all Ireland was 8.2 million in 1841 and
four-fifths of those lived in rural areas. After the famine of
1846, when many people died and many more emigrated, the
population began to decrease, so that by 1930 it was only half
what it had been in 1846. One result of this large-scale
emigration, which continued throughout the latter part of the
nineteenth and the first half of the twentieth century, was that
many people of Irish descent have made their homes in other
countries. Irish men and women have made a significant
contribution to life in Britain, the United States, Canada,
Australia, New Zealand and South Africa.
From the 1960s population numbers gradually stabilised and
between 1971 and 1986 there was a modest annual increase
averaging just over one per cent. From 1986, however, the
population declined for a few years as a result of renewed high
emigration. The total number of people living in the state in
1991 was 3,523,401, a decrease of 17,242 on the 1986 figure. The
overall density of population is 50 per square kilometre. There
is a strong and continuing movement from rural areas to towns so
that 52 per cent of the population now live in urban areas of
1,500 inhabitants or more. The rural population, which is mainly
in dispersed, isolated farmsteads, is fairly evenly distributed
throughout the country except in the mountainous areas and the
peat bogs. Densities as high as 180 per square kilometre occur
along the western seaboard, where the farms are small. Low rural
densities are associated with the larger farms on the richer land
in the east. The influence of Dublin and other urban areas is
clearly seen in the above-average densities in their contiguous
rural areas.
In Ireland (Republic) Roman Catholics comprise 95 per cent of the
community. Other denominations include Church of Ireland
(Anglican), Presbyterian, Methodist and a number of smaller
Protestant groups. They are strongest in the counties bordering
Northern Ireland, especially in Donegal (12 per cent), and in the
Eastern Region which includes Dublin, Kildare, Meath and Wicklow
(7 per cent). In Northern Ireland 65 per cent of the population
is Protestant, mainly Church of Ireland and Presbyterian. They
dominate in the three eastern counties of Ulster and comprise
40-50 per cent of the population in the west. There is also a
small Jewish community centred in Dublin, Belfast and Cork.
For the great majority of the people in Ireland, English is the
language in everyday use, but a quarter of the population claims
to be competent in Irish as well. Irish remains the first
language in the Gaeltacht (Irish speaking areas), located along
the remoter areas of the western seaboard, and in some very small
pockets of Irish speakers in West Cork, Waterford and Meath.
Urban Settlement
Even quite small village-like settlements are basically service
centres providing shopping facilities for the rural community.
The larger towns are also service centres but, in addition,
usually have industrial, administrative and commercial functions.
The main concentration of towns is in the east and south of the
country and all of the larger centres grew up as ports. Dublin
(city and county population 1,021,449), the focus of the roads
and railways, is situated where the central lowland reaches
eastwards to the Irish Sea. It is the chief commercial,
industrial, administrative, educational and cultural centre. Cork
city (127,000) has traditionally been associated with the
processing and marketing of agricultural products but it benefits
also from the presence of large-scale industrial development
around its outer harbour and the use of natural gas from the
offshore Kinsale field. Waterford (40,000), Dundalk (26,000) and
Drogheda (24,000) are smaller regional centres with industrial
functions. On the west coast, the main city is Limerick (52,000),
which is located at the lowest crossing place on the river
Shannon. It shares in the prosperity of the Shannon Industrial
Estate but its harbour facilities are now little used, though
significant port and industrial activities are developing
westwards along the Shannon estuary. Other significant western
urban centres are Galway (51,000) and Sligo (17,000).
In Northern Ireland the chief towns are Belfast (400,000), an
administrative and engineering centre with a fine harbour, and
Derry (190,000), the focus of the Foyle lowland. The new town of
Craigavon links the older urban centres of Lurgan and Portadown
and together the total population of the three towns is 72,000
people.
Agriculture
Farms and enclosed fields dominate the Irish landscape.
Two-thirds of the surface area is improved agricultural land and
much of the remainder is used by farmers as rough grazing for
cattle and sheep. Almost all the land is owned by the farmers who
work it, the former defective tenancy system as was replaced by
owner-occupancy in the late nineteenth and early twentieth
century. Farms of small and medium size predominate, over half
the holdings being 10-40 hectares. Farm size decreases westwards
and northwards and poorer land quality in the west adds to the
agricultural difficulties of the area.
Although the role of agriculture diminishes as the Economy
develops, it is still a major source of income, export earnings
and employment. Farm products contribute about 20 per cent of the
total value of exports and agriculture's share of employment is
14 per cent (7 per cent in Northern Ireland). The agricultural
labour force has halved over the last twenty-five years but the
welfare of the farming community has increased, aided since 1973
by the market outlets and financial support of the EU.
Irish agriculture is predominantly mixed pastoral farming with
some subsidiary arable cropping. The mild, moist climate and the
soils are more suitable for the growth of grass than for arable
crops. Livestock farming has been further favoured by the large
market demand for its products in Britain and continental Europe.
Livestock products account for more than four-fifths of the value
of agricultural output. Dairying is most important in the
south-west and in the north and, apart from urban supply from
areas near cities, most of the milk is processed. The beef cattle
industry is widespread: the emphasis in the west on rearing young
stock, whereas on the better land and the larger farms of midland
and eastern areas it is more on fattening. Sheep are of greatest
significance in the upland environment and in a traditional sheep
area on the dry limestone land of south Connacht. The
horse-breeding industry is most concentrated in north Leinster
with many stud farms around the Curragh in County Kildare. Pig
and poultry production was traditionally associated with the
small- farm, dairying areas of Ulster and to a lesser extent with
Munster but modern production units have been established in
other places also. Tillage occupies one-tenth of the agricultural
land, the main crops being barley, wheat, oats, potatoes and
sugar beet. They are mainly on the lighter soils in the drier and
sunnier east of the country, though oats and potatoes are better
able to tolerate conditions in the west.
Forestry
There has been an active state afforestation programme in this
century, especially since 1950. Over 400,000 hectares have been
planted by the state. There was a rapid increase in private
afforestation in the 1980s. Forests now cover 6 per cent of the
land area, but Ireland still remains the least forested country
in Europe apart from Iceland. The objectives have been to provide
a domestic supply of timber, to make profitable use of land and
to afford employment.
Forestry policy had been to use land which was less suited for
agriculture, mainly in upland and peat bog areas. There the
environmental conditions favour coniferous trees which mature
rapidly, planting being mainly of sitka spruce and lodgepole
pine. From the early 1950s the use of hardier species and of
machinery and fertilisers facilitated planting on deep peat and
in more difficult environments, resulting in a westward and
upward shift in the focus of afforestation. The remoter rural and
western areas already derive employment and income benefits but
as the forests mature and timber output increases the impact will
be much greater. Planting of land which is marginal for
agriculture has been encouraged under EU policies from the 1980s.
The recreational role of forests has increased dramatically since
the 196Os with twenty forest parks and about five hundred other
forest sites being open to the public.
Fishing
The marine environment on the continental shelf around Ireland is
generally productive of fish but the bulk of the catch has for
long been taken by the fleets of other countries and the fortunes
of the Irish fishing industry have fluctuated. From the early
196Os major development efforts were made, including harbour
improvement, provision of larger and better-equipped vessels,
training, expansion of processing, organisation of distribution
and market development at home and abroad. Fish landings expanded
dramatically but from the mid-1970s expansion of the industry was
hindered by some problems of resource supply, with the need for
restrictions on fishing.
The total catch of the Irish fleet is about 250,000 tonnes.
Mackerel is the leading fish by value, followed by Dublin Bay
prawns, cod, herring, salmon and whiting. There are many fishing
ports scattered around the coast but the principal ones are
Killybegs, Howth, Rossaveel, Dunmore East and Castletownbere, and
in Northern Ireland Kilkeel, Ardglass and Portavogie. Many fish
farms have been established along the coast, especially in the
west. They are contributing an increasing share of fish output,
with salmon being the leading variety.
Mining
Major expansion in Irish mining during the 196Os and 1970s
related mainly to the development of metalliferous resources.
Mining began at Tynagh in east Galway, at Silvermines and
Gortdrum in County Tipperary and at Avoca in County Wicklow but
production has ceased at these mines. The greatest development
has been at Navan in County Meath where production began in 1977
on one of the largest zinc-lead deposits in the world.
The most widespread mining activity is the quarrying of sand,
gravel and stone for the large construction industry. Limestone
is used as a soil improver and in cement manufacture. Other
minerals extracted include barite in Tipperary, gypsum in Cavan
and marble in west Galway.
Peat is a major mineral fuel and Ireland is the second-largest
producer in the world. It has been hand-cut as a domestic fuel
for centuries but now output is mainly by mechanised cutting,
especially on the large bogs of the central lowland. There has
been considerable offshore exploration for oil and natural gas
and in 1978 the first gas came ashore from the Kinsale Head gas
field off Cork. It is piped from Cork to Dublin and the major
towns.
Electricity
Ireland is dependent on imported fuels for the major part of its
energy supply but the policy has been to utilise native resources
to the maximum in the generation of electricity. The first major
development was the ambitious Shannon hydroelectric scheme in the
1920s, followed by harnessing of the Rivers Liffey, Erne, Lee and
Clady in the 1940s and 1950s. There is a pumped storage plant in
the Wicklow Mountains. Eleven medium to small peat-fired power
stations had begun production by the early 1960s, mainly in the
midlands. Electricity is also generated from Kinsale natural gas
in the Cork Harbour area and in Dublin.
Most of the power stations using indigenous resources are at
inland locations but all those based on imported fuels have
coastal sites and are generally of much larger size. Production
at these stations was initially from coal but later principally
from oil. Location had been mainly adjacent to the largest urban
markets for electricity in Dublin and Belfast but other
sheltered, deep-water sites have been used near Larne in County
Antrim and on Lough Foyle, the Shannon Estuary and Waterford
Harbour. There is a large coal-fired power station at Moneypoint
on the Clare shore of the Shannon estuary.
Transport
Transport in Ireland is predominantly by road. There are public
bus and freight services but most road transport is in private
vehicles. The dense road network was developed to serve a
population which was larger than at present and traffic density
is low by European standards. Yet with increasing motor vehicle
ownership there is considerable traffic congestion in and around
the major urban centres and some of the main routes are being
improved.
With the growth of competition from road transport, the railway
system which had developed in the nineteenth century contracted
through closure of light railways, branch lines, some main routes
and smaller stations. The network now comprises 2,300 km of route
way with Dublin as the main focus. The railway operates at a
substantial loss but its social benefits are recognised.
External air and sea links are vital to Ireland because of its
island location. Almost all the goods traffic and substantial
passenger movement goes by sea. The principal ports are on the
east and south coasts, most of the traffic being through Larne,
Belfast, Dublin, Dun Laoghaire, Rosslare, Waterford and Cork. The
main international airports are at Dublin, Belfast, Shannon and
Cork. Air services operate to the principal British cities and to
mainland European countries, with the main role of Shannon being
in transatlantic traffic. The considerable expansion in air
transport is reflected in the growth of the national airline, Aer
Lingus, which carries more than four million passengers annually.
Manufacturing
Much of early manufacturing development was concentrated in the
north-east of Ireland, the Lagan valley becoming the major
industrial area in the country, relying mainly on linen and
shipbuilding. When both of these industries fell into decline,
diversification of the industrial structure became a major
objective of policy in Northern Ireland and a variety of new
industries were established, principally of British origin and
mainly in the east.
In the attempt to develop an industrial sector the Irish
Government followed at first a protectionist policy with the
objective of establishing Irish-owned manufacturing to serve the
home market. There was a major reversal of policy from the late
1950s, with the initiation of a movement towards free trade and
promotion of export-oriented industry. Foreign involvement has
been actively encouraged, the main investment coming from the
United States, Britain and Germany. Factory employment is now
three times what it was at the time of independence. There had
been a high degree of industrial concentration in Dublin and the
main urban centres but state policy has been to bring
manufacturing to other towns also and to favour development in
the west by making higher grants available to firms establishing
there.
The principal sectors in Irish manufacturing are metals and
engineering, the food, drink and tobacco industries, and textiles
and clothing. Industries in which there has been substantial
recent growth include light engineering, electronics, synthetic
fibres, pharmaceuticals and plastics.
The food and drink industries are more widely dispersed
throughout the country than are other forms of manufacturing,
since their raw materials are for the most part produced in rural
areas. The remainder of manufacturing is more concentrated in the
main industrial centres, principally Belfast and Dublin. With
decline in some of the industries in these centres and the
establishment of new factories throughout the country, the trend
has been towards greater decentralisation of manufacturing .
Tourism
There has been major growth in Irish tourism since the Second
World War, related mainly to increased affluence, improved
transport facilities and greater promotion and organisation of
the industry. A severe setback occurred in the years 1969-72,
principally as a result of violence in Northern Ireland, and
subsequent recovery has been slower in the north. Tourism plays
an important role in the balance of payments, with over three
million people visiting the country annually. Visitors come
mainly from Great Britain but also from continental Europe, North
America and other areas. There is also substantial tourist
traffic within the country.
The tourist attractions of Ireland include the relaxed atmosphere
and friendliness of the people, the clean rural environment, the
varied and attractive scenery, the important historical and
literary associations and the opportunities to participate in
recreational activities. There is also a major ethnic factor,
with emigrants returning home on holiday and people of Irish
descent visiting relatives and places of ancestral connection.
Tourism is strongly oriented towards the coastal zone, which
offers the attractions of the sea, scenic landscapes and the
major cities and towns. Dublin is the single most important
centre but the western seaboard is the part of the country having
the greatest tourist appeal.
Other Services
Growth of the service or tertiary sector has been a major feature
of economic development in recent decades. It accounts for 60 per
cent of employment, the role of services being greater in
Northern Ireland. The principal service categories are
educational and medical services, retail and wholesale
distribution, public administration and defence, transport and
communication, the insurance, finance and business service group,
and varied personal services. The spatial patterns of individual
services differ but they are essentially urban activities because
of the need to be accessible to consumers and because of
interrelationships between services. The high degree of
concentration in the major urban centres, especially Dublin and
Belfast, and the consequent increase in office activities have
been reflected in the extent of office building development.
There is an international off- shore services centre at the
Custom House Dock in Dublin.
Regional Development
Regional imbalances in population trends, employment, income and
related social conditions have for long been a feature of
Ireland. The most striking traditional contrast is between the
more prosperous east and the less developed west, though this
twofold distinction is a simplification of a more complex
regional pattern. The less developed character of the west can be
explained mainly in terms of its more difficult physical
environment, its remoteness from external influences, markets and
financial sources, its heavy dependence on small-farm agriculture
and its lower levels of urbanisation and infrastructural
provision. The result has been low incomes, high unemployment and
underemployment and heavy migration from the area with its social
consequences. In recent times inner Dublin and the central
districts of other cities have been recognised as problem areas
also.
Attempts have been made to counteract regional imbalance since
the 1950s, at first focusing exclusively on the west but later
promoting western development within a broader regional planning
framework. The Irish-speaking Gaeltacht areas have been
particularly favoured in welfare promotion. The major initial
incentive was the allocation of direct state grants to
manufacturing firms locating in the west, and although grant
provision was later extended to all parts, a differential was
maintained in favour of western areas. The largest manufacturing
concentration of this type is at Shannon, where an industrial
estate was developed as part of a plan to promote traffic through
the airport. While manufacturing remained the spearhead of
regional policy, development efforts in other sectors assumed an
increasing regional dimension, as in agriculture, forestry,
fishing and tourism. Some decentralisation of government
administration has been introduced. In recent years there has
been a growing realisation of the role which service industries
could play in regional development.
Within Northern Ireland there is also a core- periphery contrast;
the main area of development comprises much of Antrim, Down and
north Armagh, with most of the remainder, in particular the west,
lagging behind. The more peripheral parts tend to be
characterised by population, religious and political differences,
by a weaker urban structure with more limited economic
opportunities and by higher unemployment and emigration rates.
Development measures have included infrastructural improvement,
advance factory provision and higher industrial grants.
Most of the geographical features of Ireland influence the
spatial pattern of economic and social development. In turn, the
extent to which regional development policies are effective, both
north and south, will have a major bearing on the future
geography of the island.
