Key message

The rate and nature of land use changes indicate where future environmental pressures are likely to arise. By European standards, Ireland has experienced a relatively high rate of land use change since the early 1990s.

Introduction

Land is subject to many competing demands. We rely on our land resource for food, energy, forestry, recreational opportunities and overall, for a good living environment. Current land use is the result of a sequence of past human interventions on the natural landscape. Agriculture remains the predominant land use in Ireland, although economic development and population growth since the mid 1990s, have led to an increase in the extent of built-up areas, with growth rates surpassing those of our European neighbours.

The soil of Ireland is an immensely valuable, and finite, national resource, which forms and evolves slowly over very long periods of time. Soil is a biologically active, complex mixture of weathered minerals, organic matter, organisms, air and water that provides the foundation for life in terrestrial ecosystems.  The general consensus is that soil quality in Ireland is good; however, this is based on limited information.

The state and impacts

Afforestation

Since 1997 policies have been in place to increase broadleaf planting, and the Rural Development Programme 2007-2013 sets a target of 30 per cent annual broadleaf afforestation. This target has been reached (and exceeded) in recent years, but primarily through a reduction in afforestation using coniferous trees rather than in increase in planting of broadleaves.

Land Cover

Landcover in Ireland is dominated by agriculture (66 per cent) with pasture comprising over 50 per cent. Peat bog and wetland occupy almost 19 per cent and forestry 12 per cent. The surface area occupied by artificial areas has increased from 1.99 per cent to 2.28 per cent between 2000 and 2006.

State and Impacts

Land Cover

Irish land cover is primarily agricultural, followed by bogs and wetlands and forestry. The Irish landscape has experienced continual land cover changes for centuries, but there has been a relatively high rate of land use change by European standards since the early 1990s. For example, the area under forestry has increased a quarter to over 10 per cent of national land cover, and the area of artificial surfaces (residential and industrial buildings, roads  etc.) increased by approximately 15 per cent since 2000 to 2.3 per cent of land cover.  There has been significant development on the periphery of many urban areas across Ireland. Similarly, rural areas have experienced widespread construction of single rural dwellings and the suburbanisation of villages close to towns and cities.

Approximately 75 per cent of the national forest estate is predominantly conifer, comprised mainly of commercial timber species but also including some native species such as Yew and Scots Pine. The remaining 25 per cent of the forest estate is predominantly broadleaf and mixed forest, of which approximately half is comprised of native broadleaf species such as Oak, Ash, Birch, Hazel, Alder etc. The proportion of broadleaf to coniferous species planted in recent years has increased, although the actual levels of planting have remained somewhat static.

Soil

A limited amount of information is known about Irish soils, but a late introduction into the industrial revolution preserved our soils from large amounts of contamination. The large percentage of permanent pasture land and our temperate climate have protected Ireland’s soils from serious degradation.  The general consensus is that soil quality in Ireland is good; however, this is based on limited information and therefore the degree of certainty is low. The production of a National Soils Database (2007) and the EPA Historic Mine Sites – Inventory and Risk Classification project (2010) has provided much needed baseline knowledge on soils in Ireland.

Forestry

Following a long period of afforestation, which began in 1904, forest cover has increased from 1 per cent to over 10.7 per cent of land cover. This compares with a European average of over 30 per cent. The strategic plan for the Irish forestry sector sets a national planting rate target of 20,000 ha per annum, and a target for forestry to reach 17 per cent of land cover by the year 2030. Recent planting rates have fallen well short of this target.

The key drivers and pressures

Total house completions

Total house completions increased by 378 per cent between 1990 and 2006 when this activity reached its peak. Since then there has been a dramatic fall in house completions such that by 2009 the level was back to that of the mid 1990's.

Drivers & Pressures

Land is subject to many competing demands. Current land use is the result of a sequence of past human interventions on the natural landscape.

The principal causes of land use changes in urban areas have been the development of housing and associated commercial services built to cater for the growth in the population and the migration to suburbs, satellite towns and villages. In the 25 years between 1970 and 1995 an average of 23,000 new homes were constructed in Ireland every year. In the ten years between 1996 and 2007 an average of 60,000 homes were constructed per year, peaking with 93,000 in 2006.   In recent years however, there has been a significant fall-off in new housing completions.

A natural consequence of peripheral urban development is increased traffic volume; this often results in congestion and longer commuting times. As some villages and towns grow beyond the capability of the local infrastructure to support them, overloaded wastewater treatment plants or inadequate drinking water supplies pose a risk to health and the environment.

The scattered nature of Irish rural development has made the provision of public services, including wastewater services, more expensive and less economically viable. In many rural areas the majority of the population uses individual septic tanks, which pose a risk of pollution of groundwaters, surface waters and public water supplies if poorly sited and/or not properly maintained.

Other threats to Ireland’s land resource arise from intensification of agriculture, poorly managed commercial forestry, peat extraction, land clearance and development.

Soil can be contaminated by a wide range of potential pollutants, through either local (point source) contamination or diffuse contamination. Contamination from point sources can arise as a result of leakages and accidental spillages from commercial activities e.g. petroleum storage tanks, old gas work sites, timber treatment or landfills. Diffuse contamination can arise from activities such as agriculture, forestry, horticulture and landspreading of organic wastes.

The 2020 outlook

Outlook

The trend earlier in the decade towards a continuation of market-driven, low-density residential development on the periphery of cities and the suburbanisation of satellite villages and towns has come to an abrupt end.  The collapse of the property market, a slow recovery from economic recession, as well as a significant deficit in public finances means that it is likely to be some years before there is pressure again to convert significant amount of land for development purposes.

Nonetheless, the issues of spatial planning, land use and soil quality are intertwined and interdependent, and this should be reflected in integrated policies and plans at national, regional and local level. The continued uptake of the SEA Directive across all economic sectors will therefore be important.

It is possible that many soil threats and pressures, such as erosion, surface sealing and compaction, are occurring in Ireland, but no comprehensive assessment has been made to date. These threats, along with the potential impacts of climate change, need to be evaluated, quantified, prioritised and addressed.

While Ireland has fewer contaminated land problems than most other heavily industrialised countries, there is no overall policy framework for the identification, management and remediation of contaminated land in Ireland. National legislation dealing specifically with soil contamination needs to be developed, including a mechanism for remediation of sites.

Distribution of SEA plans/programmes

Strategic environmental assessment has been a legal requirement since July 2004, and has been applied at national, regional, county and local levels across different sectors as identified in the SEA Directive. As of November 2010, a total of 238 SEAs were at various stages. There has been good uptake on SEAs in most sectors although the Planning/Land Use sector has had the most significant take-up. A number of significant sectors have not undertaken SEA to date, in particular forestry, tourism and telecommunications.

Responses

Strategic Environmental Assessment

The EU Strategic Environmental Assessment (SEA) Directive became a legal requirement in Ireland since 2004. The main objective of SEA is to provide environmental protection and to implement environmental considerations into plans and programmes with the promotion of sustainable development.  SEA is mandatory for certain plans/programmes in the areas of agriculture, forestry, fisheries, energy, industry, transport, waste management, water management, telecommunications, tourism, town  and country planning and land use.

Of the sectors specified in the Directive, Land Use Planning has had the most significant take-up.  While many of the economic sectors are now beginning to address the requirements of the SEA Directive, it is notable that a number of significant sectors, in particular the forestry, tourism and telecommunications sectors, have yet to engage fully in the process. The effectiveness of SEA in Ireland is currently being assessed through a study initiated by the EPA.

Historic Mine Sites

An inventory and assessment of historic mine sites was published by the EPA and the Geological Survey of Ireland in 2010. This concluded that of the 32 mining districts assessed, 22 districts will not require any interventions, seven districts will require further monitoring and three districts (Tynagh, Silvermines and Avoca) will require additional site-specific risk assessment by the landowners. A comprehensive remediation project is currently underway at the Silvermines site, while a full assessment of the Avoca site, where the State is the landowner, has recently been completed.

Soils

A National Soils Database (NSDB) has been developed through a research project funded by the EPA. This database has provided Ireland with a baseline soil geochemical atlas. It provides data point and spatial distribution maps for 45 elements, including major nutrients such as phosphorus and potassium, as well as trace elements. The Irish Soil Information System project is a current research project funded by the EPA and being undertaken by Teagasc. This aims at producing a national digital soil map at a 1:250,000 scale with the associated soil information system for Ireland by 2014. The latest spatial mapping technologies are being utilised for this project, bringing soil mapping into the 21st century.
