Soil degradation 183

3.6. Soil degradation

The main problems for soils in the EU are irreversible losses due to increasing soil sealingand soil erosion, and continuing deterioration due to local contamination and diffusecontamination (acidification and heavy metals). The incremental loss and deterioration ofEuropes soil resource will continue, and will probably increase as a result of climatechange, land-use changes and other human activities.

Soil degradation is mainly caused by urbanisation and infrastructure development (inwestern and northern Europe) and erosion (in the Mediterranean region). There is asignificant risk of water erosion mainly in southern and central Europe and the Caucasusregion; at present, this risk is high to very high in one-third of Europe.

In the EU, policies are in place to prevent an increase in local soil contamination, which ishigh in areas with heavy industries and military bases. However, the problem of existingcontamination remains and there is a danger of further contamination in the AccessionCountries.

Diffuse contamination is particularly significant in areas with intensive agriculture.Southern Europe is increasingly affected due to increased industrial activity, urbanexpansion, tourism and agricultural intensification, while soils in northern Europe areprone to the effects of acid deposition.

Strategies for soil protection, and systems for monitoring of soil, are not adequatelydeveloped at European or national level, as compared with air and water for whichmonitoring, assessment and policy frameworks are already in place. A policy framework isneeded which recognises the environmental importance of soil, takes account of

problems arising from the competition among its concurrent uses (ecological and socio-economical), and is aimed at maintaining its multiple functions.

Main findings

1. Why are Europes soils degrading?

1.1. The issueSoil must be considered as a finite, non-renewable resource since its regenerationthrough chemical and biological weathering

of underlying rock requires a long time. Inhumid climates, for example, it takes 500

years on average for the formation of only2.5 cm of soil (The Tutzing Project, 1998).

Notwithstanding the limitations of availableinformation (see detailed discussion inChapter 4.2), it is clear that the damage tosoils caused by human activities is increasing,and manifested for instance in rates oferosion 10-50 times higher than the rates ofnaturally induced erosion. Pressure on soilsresults from agricultural intensification(including consolidation of small fields intolarger units) (see Chapters 3.13 and 3.14),and population growth coupled with increas-ing urbanisation (see Chapters 2.3 and3.12).

Soil is affected in terms of loss or deterio-ration of its functions (Box 3.6.1). A varietyof economic sectors all play a part in contrib-uting to soil degradation. As a consequence,approaches to solving soil problems must bebased on multi-layered and integrated

measures (Figure 3.6.1).

Some of the problems and their conse-quences are irreversible, such as soil losses,mainly due to erosion and soil sealing. Otherscan be improved with adequate measures,such as clean-up and remediation plans set upto eliminate local contamination.

1.2. Assessing the impacts of economic activities on soilThe capability of soil to provide a support tolife and ecosystems can be expressedthrough its ecological and socio-economicfunctions (Box 3.6.1).

Competition in terms of space exists betweenthe ecological and the socio-economic

functions, as well as among concurrent usesof soil within each group of functions.

For example, the use of land for infrastruc-ture construction irreversible in relation toseveral generations time scale makes soil

unavailable to ecological functions. Mean-while the over-intensive use of soils bymodern farming imposes too heavy a burdenon the buffer, filter, transformation, andgene-protection functions, resulting incontamination of the food chain and/orgroundwater, as well as the destruction ofplant and animal species. (Blum, 1990).

The concept of multiple soil function andcompetition is crucial in understandingcurrent soil-protection problems and their

multiple impact on the environment (Figure3.6.1). Accordingly, a conceptual assessmentframework has been developed applying theDPSIR approach to soil issues (Figure 3.6.2).This of course requires development ofindicators for soil degradation and loss ofsoil functions (see also chapter 4.2).

Soil quality and functions are of greatimportance for the environment. They areinterrelated with other key environmentalissues such as (see Figure 3.6.1):

biodiversity: including gene reserve andprotection, biomass production, protec-tion of landscapes (see Chapter 3.11);

water stress: soil has a filtering/bufferingcapacity, but there are threats fromcontamination, salinisation andeutrophication (see Chapter 3.5);

dispersion of hazardous substances, dueto run-off or leaching (see Chapters 3.3and 3.5).

1.3. Driving forces and pressures affecting soil

from main economic activities

1.3.1. Land development, transport and tourismPressures on land use are particularly associ-ated with urban sprawl (see Chapters 2.3,3.12 and 3.13), increasing mobility (seechapter 2.2) and tourism (see Chapters 3.14and 3.15).

A predicted 5% increase in the urbanpopulation between 1990 and 2010 will,according to present trends, require an

Box 3.6.1. Soil and soil functions

Many different definitions of soil exist, according tothe particular context, purpose, and point of viewfrom which soil issues are approached. This report,which considers soil with its multiple functions andimpacts as having a fundamental role in Europes

Environment, requires a broad definition such asthat adopted by the Council of Ministers of theCouncil of Europe in 1990:

Soil is an integral part of the Earths ecosystemsand is situated at the interface between the Earths

Ecologicalfunctions

Socio-economicfunctions

Production of biomass

Filtering, buffering andtransforming

Gene reserve and protectionof flora and fauna

Support to human settlements(housing and infrastructure,recreation) and waste disposal

Source of raw materials,including water

Protection and preservation ofcultural heritage

Soil produces food and fodder, providing nutrients, air,water. It provides a medium in which plants can penetratewith their roots.

This function enables soils to deal with harmful substances,mechanically filtering organic, inorganic and radioactivecompounds; adsorbing, precipitating or even decomposingand transforming these substances - thus preventing themfrom reaching the groundwater or the food-chain.

Soil protects numerous organisms and micro-organismswhich can live only in soil.

Soil provides ground for the erection of houses,industries, roads, recreational facilities and wastedisposal.

Soil provides resources of numerous raw materials,including water, clay, sand, gravel and minerals, as well asfuel (coal and oil).

Soil, as a geogenic and cultural heritage, forms anessential part of the landscape and is a source ofpaleontological and archeological evidence, relevant forthe understanding of the evolution of earth and mankind.

Source: Blum, 1990, 1998Soil degradation means loss or deterioration of itsfunctions. For the purpose of this report, it includes bothsoil loss and soil deterioration. Soil losses due to sealingand erosion can be considered in large part as irreversible

environmental point of view, the concept of soilalso embraces porous sedimentary rocks and otherpermeable materials together with the water whichthese contain and the reserves of undergroundwater. (Council of Europe, 1990).

Box 3.6.2. An emerging issue: the relationships between soil and climate change

The Kyoto Protocol recognises the need to consideradditional human-induced activities related tochanges in greenhouse gas emissions by sourcesand removals by sinks in the categories ofagricultural soils, land-use change and forestry. So

far only activities related to forestry (afforestation,reforestation and deforestation) since 1990 havebeen regulated. Reliable and transparentmethodologies, and guidelines on how to take intoaccount additional sources/sinks still need to bedeveloped (see Chapter 3.1; UNFCCC, 1998)

Soil can act as a carbon sink. This also hasimplications for the bio-availability and mobility ofmetals in soils, and has potentially harmful effectson both human, plant and animal health.Soil can also act as a carbon source, as well as asource of other greenhouse gases. The directapplication of agro-chemicals in the industrialagricultural sector, and other related managementpractices, can promote micro-organism activity insoils, and result in increased emissions of nitrousoxide (N2O), methane (CH4) and carbon dioxide(CO2) to the atmosphere, hence contributing toclimate change (see Chapter 3.1).

In boreal soils, reduction in the extent and depth ofpermafrost due to global warming could lead to anadditional flux of CO2 into the atmosphere, andcontribute to the release of CH4stored in the soil(IPCC, 1996).

Desertification and climate change

Desertification is land degradation in arid, semi-arid and sub-humid areas resulting from variousfactors, including climatic variations and humanactivities (UNCCD, 1997). Some southern parts ofthe EU, including Spain, Greece, Portugal, Italy andFrance (Corsica) are affected (EEA,1998).

The modified patterns of precipitation, consequentto climate change, will probably induce greaterrisks of soil erosion, depending on the intensity ofrain episodes (IPCC, 1998).

Desertification is likely to become irreversible if theenvironment becomes drier and the soil becomesfurther degraded through erosion and compaction(IPCC, 1996).

equal increase in the uptake of urban land(see Chapter 2.3).

Some EU, national and regional policiesseem to encourage these sprawling trends:for instance, over the next decade, it is

planned to extend the length of railways byapproximately 12 000 km, of which 10 000km is high-speed track and the road networkby over 12 000 km (implementation of theTENs; see Chapter 2.2).

The major impacts of these developments onsoil are its irreversible loss: through surfacesealing, affecting the most productiveagricultural and forest land; together withsoil erosion, due to destruction of plantcover; local contamination due to waste

accumulation; and salinisation caused by theabstraction and use of marine water incoastal areas.

Expansion of transport infrastructure andtraffic emissions are also affecting soil interms of diffuse contamination (heavymetals, soil acidification), while road spillsand facilities connected to the transportsector (petrol stations and car-repair facili-ties) contribute to the generation of localsoil contamination.

The consequences are observable in nearlyall big cities and urban agglomerations inthe EU, such as London, Paris and the Ruhrarea (see Chapter 3.12, Box 3.12.6). Tourismaffects mainly the Alps, Mediterranean

coastal areas (which account for 30% of thetotal tourist arrivals in the EU), and sub-tropical islands (Canaries, Madeira).

1.3.2. AgricultureThere are marked regional imbalances in

the EU between agricultural intensification changes largely driven by the implementa-tion of the CAP and economic pressureson marginal farms. The latter causes landabandonment, which may accelerate soildegradation, and, in areas with a dry climate,may lead to desertification.

Intensive industrial agriculture gives rise tosevere (and increasing) pressures on agricul-tural soils, which represent approximately40% of the EUs total soil resource (see

Chapter 2.2).

The major impacts on soil are (GermanAdvisory Council of Global Change, 1994):

increased susceptibility to wind andwater erosion as a consequence ofagricultural practices (long exposure ofploughed soil, loss of organic matter,cultivation on steep slopes, etc.);

loss of grazing cover and erosion due toovergrazing;

loss of fertility due to deep ploughing,elimination of crop residues, mono-culture and elimination of mixedcultivation/animal farming;

soil compaction by heavy machines, withincreased run-off.


5/20


These problems, initially focused on zoneswith fertile soils in Europe, are now wide-spread at continental level, as industrialagriculture has spread to regions with lessfertile and more vulnerable soils, such as theMediterranean area.

1.3.3. Industry, energy and mining

These sectors are affecting soils both interms of local contamination, mainly due toinadequate waste management and produc-tion processes, and diffuse contamination,due to emission and transport of pollutants

via air, water and earth often in regions farfrom the original source (Box 3.6.3).

Local soil contamination most frequentlyoccurs at waste-disposal sites, gas works, oil

refineries, metal-processing industries,chemical industries and other productionfacilities.

The extraction of minerals, metals andconstruction materials can be anothersource of pollution, leading to: local con-tamination; destruction of arable land;changes in morphology and consequentlyerosion and hydrological disruption; andcompaction, surface sealing and soil loss.

2. What is the current state of Europes soils?

Although soil degradation at European levelis generally recognised as a serious and

widespread problem, its quantification,geographical distribution and total areaaffected are only roughly known.

The most recent assessment of soil condi-tions in Europe is an evaluation of thecurrent state of human-induced soil degrada-

tion, derived by ISRIC in 1993 from theworld map on the status of human-inducedsoil degradation (GLASOD) (Maps of soildegradation in Europe, prepared by ISRIC,are published in EEA, 1998). There is a needfor better, and more detailed information.

Validation of the maps through the EIONETis ongoing.

2.1. Soil loss by urbanisation and infrastructures

The rates of real soil loss due to surfacesealing through urbanisation and infrastruc-ture construction in the EU are consistent.Since 1970, the increase of length of motor-

ways has been significant in most of thecountries. Occupation of land by infrastruc-ture is high in Belgium, Germany and theNetherlands, and is increasing in Greece,

Industry direct chemicals industry, petrochemical/oilindustry, steel industry and other

Energy direct gas works, petrochemical/oil industry

Transport direct and accidents (road spills), maintenance of indirect transport vehicles, inadequate interim

storage of hazardous chemicals

Household/ indirect production of wasteConsumers

Tourism indirect production of waste

Military direct military bases: production of war fareagents, shooting ranges, stocks, air strips,car-repair shops

Box 3.6.3. The causes of local contamination

Contaminated sites are mostly due to industrial activities and waste disposal.

Waste disposal addresses most sectors, namely industry, households andconsumers but also tourism.

The transport sector contributes to local soil contamination due to road spillsand the huge number of repair and maintenance facilities.

Abandoned military bases pose a very serious problem in most of theAccession Countries, especially those of the former Soviet army forces. Localsoil contamination at military bases is mostly due to air strips, vehicle repairand maintenance facilities, production of warfare agents, storage of chemicalsand fuels, and shooting ranges.

The energy sector contributes to the problem with gas works and caloricpower stations.

Portugal and Spain (see Chapter 2.2, Table2.2.1).

There is a lack of consistent data on theamount of soil loss through surface sealingat the EU level. Data on the total amount ofbuilt-up areas is only available for a limitednumber of countries, and is not comparable

since countries use different methodologies.Within these limitations, existing data showsthat since 1990 the growth of built-up areashas been consistent in Belgium, France andGermany, where it reached about 50 and 70ha/day over the period 1990-1995 in Bel-gium and France respectively, and exceeded120 ha/day over the period 1993-1997 inGermany (Table 3.6.1, Figure 3.6.4).

Built-up areas have grown at the expenses ofagricultural land in France, Germany, theNetherlands, Poland and Iceland whereforest areas have also decreased in theperiod 1990-1995 (Figure 3.6.3).

Soil loss rates through land developmentand infrastructures may exceed those due to

soil erosion in many EU countries, with thelikely exception of some countries in South-ern Europe (see Table 3.6.3).

2.2. Soil erosionSoil erosion in Europe is mainly due to waterand to a lesser extent to wind. The major

causes are unsustainable agricultural practicesand overgrazing. Soil erosion reduces theecological functions of soil: mainly biomassproduction, crop yields due to removal ofnutrients for plant growth, and soil filteringcapacity due to disturbance of the hydrologi-cal cycle (from precipitation to runoff).

The loss of plant nutrients and organicmatter viaeroded sediment reduces thefertility and productivity of the soil. Thisleads to a vicious cycle whereby farmers

apply more fertilisers to compensate for theloss of fertility. Soil, once eroded, tends to bemore susceptible to further erosion, andthus the cycle intensifies. The loss of appliednutrients in this way, represents an enor-mous cost to the agricultural community.

It has been calculated that in Austria, poten-tial loss of organic matter in agricultural soildue to erosion could be more than 150 000tonnes per year, while potential loss ofnutrients, such as nitrogen and phospho-rous, could be more than 15 000 and 8 000tonnes per year respectively (Stalzer, 1995).

2.2.1 How much soil is being eroded?

Soil erosion causes irreversible soil loss overtime-scales of tens or hundreds of years and

is an increasing phenomenon in Europe(Blum, 1990). In parts of the Mediterraneanregion, erosion has reached a stage ofirreversibility and in some places soil erosionhas practically stopped through lack of soil.

With a very slow rate of soil formation, any

soil loss of more than 1 t/ha/year can beconsidered irreversible within a time span of50-100 years. Losses of 30-40 t/ha in indi-

vidual storms that may happen once everyone or two years are measured regularly inthe EU, with losses of more than 100 t/ha inextreme events (Van Lynden, 1995).

The amount of soil loss from erosion in theEU is not known. The area affected by watererosion and yearly amounts of soil loss forselected countries in the period 1990-1995

are shown in Tables 3.6.2 and 3.6.3. Figure3.6.5 shows distribution of loss per land-useclass in the same period.

Soil losses are high in Spain, where loss ofsoil in agricultural land reached a peak of anaverage 28 t/ha/year, in the period 1990-1995, while the total area affected was 18%of the total land in 1995. Substantial losseshave been calculated for Austria, where anaverage of more than 9 t/ha/year in agricul-tural land losses affected an area of approxi-mately 8% of the total land.

2.2.2 Where in Europe?

Although it has always been considered as asevere and increasing problem in southernEurope, soil erosion, especially due to water,is becoming increasingly relevant in north-ern Europe. The area with the greatestseverity of soil loss for both wind and watererosion is the Balkan Peninsula and thecountries surrounding the Black Sea. Somecentral European Countries such as theCzech Republic and the Slovak Republic,

also suffer from extremely serious soilerosion problems (EEA, 1998).

The EU Mediterranean countries have severesoil erosion problems, which can reach theultimate stage and lead to desertification. Atpresent rates of erosion, considerable areas inthe Mediterranean and the Alps, currentlynot at risk, may reach a state of ultimatephysical degradation, beyond a point of noreturn within 50-75 years. Some smaller areashave already reached this stage (Van Lynden,1995).

third of the European land area. Areas withsuch high risk are dominantly located insouthern and central Europe and the Cauca-sus area. In the remaining parts of Europethe risk is low to moderate.

Under the baseline scenario, the watererosion risk is expected to increase by 2050in about 80% of the EU agricultural areas, asan effect of climate change. It remains thesame in 10% of the areas and decreases inthe remaining 10%. The areas with highestincrease in erosion risk are mainly located inthe western part of central Europe, in theMediterranean area, and in the north andsouth of the Black Sea. Areas with 10% ormore decrease in risk can be found acrossthe EU (parts of UK and Spain), but are

mainly located in the areas south or south-east of the Gulf of Bothnia (Maps 3.6.1 and3.6.2).

2.3. Local contaminationLocal contamination is a characteristic of

regions where intensive industrial activities,inadequate waste disposal, mining, militaryactivities or accidents pose a special stress tosoil. If the natural soil functions of buffering,filtering and transforming are overexploited,a variety of negative environmental impactsarise, the most problematic of which are

water pollution, direct contact by humanswith polluted soil, uptake of contaminants byplants and explosion of landfill gases.

2.3.1. How many contaminated sites are there in

Europe?There is no European-wide monitoring ofcontaminated sites. Monitoring exits only ona country-by-country basis. Countries are atdifferent levels of progress and apply differ-ent methodologies and definitions.

Several countries have initiated nationalinventories. However, data on the number ofcontaminated sites based on national inven-tories is not currently comparable, since it isbased on different national approaches.Therefore, national totals do not represent

the scale of the problem, but give only anindication of the efforts made by eachcountry.

Information available for 20 Europeancountries reveals that the estimated total ofsites which are definitely or potentiallycontaminated exceeds 1.5 million and thatthese are mostly located in 13 EU MemberStates (Table 3.6.4).

2.3.2 Where in Europe?

Land contamination usually affects areaswith a high density of urban agglomerationand with a long tradition of heavy industry,or in the vicinity of former military installa-tions. However, a single site may pose amajor threat to a large population group orto a vast area, as for the mine of Aznacllar(Andalusia, Spain), where an accidentoccurred in April 1998 and provoked thecontamination of an area of about 4 500 ha,threatening the national park of Doana(Box 3.6.4).

The largest and most affected areas arelocated in north-west Europe, from Nord-Pasde Calais in France to the Rhein-Ruhr regionin Germany, across Belgium and the Nether-lands. Other areas include the Saar region in


9/20


Germany; northern Italy, north of the riverPo, from Milan to Padua; the region locatedat the corner of Poland, the Czech Republicand the Slovak Republic, with Krakow andKatowice at its centre; and the areas aroundall major urban agglomerations in Europe.

In order to identify hot-spots for localcontamination, an integrated inventory ofpollution sources to air, water and land isneeded.

2.3.3 What is being done? Investigation and remediation of contaminated land in Europe.Identification of sites posing a potential riskto human health and ecosystems (identifica-tion of potential contamination through thescreening process), verification that a

contamination exists, and assessment of therisks involved are the first steps in themanagement of contaminated land beforeany remediation activity can take place.

Progress in the identification of contami-nated sites in some European countries issummarised in Figure 3.6.6. In Denmark, forinstance, screening has been completed for93% of suspected sites and risk assessmentfor 26% of the definitely contaminated sites;in Austria, the percentages are 9% and 35%respectively. It is not possible at present to

make a more comprehensive assessment ofprogress in the management of contami-nated land in the EU, because the availableinformation is far from complete.

Many countries have developed specialfunding tools for the clean-up of contami-nated sites, such as tax systems, new land-useincentives or the prevention of new contami-nation. Public expenditure on clean-up andremediation of contaminated sites for se-lected countries is illustrated in Table 3.6.5.

In the EU, policies now in place reflecting theprecautionary principle will help to avoidcontamination in the future. Thus expendi-ture on the clean-up of contaminated sites

will stabilise or even decline, except incountries which have only recently begun toaddress the problem. Monitoring activities

will increase; many countries have onlyrecently started to set up a monitoring system.

At EU level the programmes of the Euro-pean Regional Development Fund providesome support for the clean-up of local soilcontamination (Table 3.6.6).

Many Accession Countries have enactedlegislation for contaminated sites, started

inventories and set up specific funding tools.Hungary and the Czech Republic can beregarded as the most advanced in thisrespect. The Slovak Republic and Sloveniaare working on a new regime includingfinancing models. Lithuania, Latvia, Hun-

gary and the Czech Republic have started toset up inventories, while all AccessionCountries have made assessments of the costsof remedial measures for former militarybases. Co-operation with the EU is increas-ing.

2.4. Dif fuse contaminationSoils are often used for the disposal ofindustrial and urban waste products. Con-taminants from flowing water over soil oreroded soil itself can pollute surface waters

such as rivers, streams and reservoirs. Leach-ing of contaminants through channels in thesoil via preferential flow is a large source ofchemicals in groundwater (see Chapter 3.3).

Soil characteristics play a major role in themovement of chemicals within the soil.Movement of chemicals that adsorb tomineral or organic soil particles is governedmainly through erosion mechanisms,

whereas transport of soluble chemicals tendsto be via water flow either through the soilor as surface runoff. Many chemicals exhibit

both partial adsorption and solubilisation,making predictions of their fate, behaviourand environmental impacts difficult (seeChapter 3.3).

The soil function most affected by diffusecontamination is its buffering, filtering andtransforming capacity. When the bufferingcapacity of soil with respect to a certainsubstance is exceeded, the substance isreleased to the environment. This delayedrelease of pollutants is very dangerous and

renders the soil a chemical time-bomb.

The most relevant problems posed by diffusecontamination and treated here are soilacidification, soil contamination by heavymetals and chemicals, and surplus nutrients.

2.4.1 Soil acidificationSoil acidification occurs as a result of emis-sions from vehicles, power stations, otherindustrial processes and natural bio-geochemical cycles, re-depositing onto thesoil surface mainly via rainfall and drydeposition (see Chapter 3.4).

Exceedances of critical loads of acidificationand eutrophication are at present mostlydominated by nitrogen deposition. The

In April 1998, a tailing-dam dike in an open-castpyrite mine at Aznalcllar (Seville, Spain) breached,allowing water and solid materials from the tailingspond to be discharged into the nearby Agrio river,an affluent of Guadiamar. About 4.5 million cubicmeters of slurry composed of acidic water, finedivided metals (mainly pyrite) and other materialsinundated the riverbanks of the Agrio andGuadiamar rivers threatening Doana, Europeslargest national park. A strip of ca. 300 m wide and40 km long, at both sides of the rivers, was coveredby a layer of toxic black sludge. About 4 500 ha ofagricultural land became polluted.

Studies carried out immediately after the spillingshowed that the sludge were composed mainly ofpyrite (68-78%) in very fine particle size. Chemicalanalysis of the sludge showed a great content inheavy metals and other toxic elements (Cabrera etal., 1998).

Box 3.6.4. The accident of Doana

A year later 68% of soils are still contaminated withhigh and very high concentrations of heavy metals.With reference to the arable layer up to a depth of10 cm, 68% of soils are contaminated with arsenic,47% with zinc, 25% with lead, 15% with copper,11% with tallium and 4% with cadmium. The mostcontaminated areas are located close to the mineand in the surroundings of the park.

Although remediation started soon after theaccident and current measures allow theimmobilization of a large part of the contaminants,the re-use of affected land is still a major problem.

Figure 3.6.6.Progress in identification of contaminated sites inselected countries as % of estimated total

situation is not homogeneous over Europe,and some hot-spots have been identified.

A survey to assess the effects of acid deposi-tion on European forest soils began in 1989as a joint initiative of the International Co-

operative Programme on Assessment andMonitoring of Air Pollution Effects on Forestin the UNECE region (ICP Forests) and theEU Scheme on the Protection of Forestsagainst Atmospheric Pollution. Although acommon methodology for sampling andanalysis was adopted in most countries,differences in national methods used exist.Moreover, information is available only for asubset of sites. Further analysis is needed tosubstantiate large-scale impacts of aciddepositions on forest soils.

Information from 23 European countries(including the EU Member States) reportedacid topsoil conditions in 42% of the 4 532sites covered, and indicated a relationshipbetween acid deposition and soil acidity.Extremely acid conditions (defined as amineral surface layer pH below 3.0) werereported in 1.9% of sites, mainly located inregions receiving a very high atmosphericdeposition load, and often where the soilshave an extremely low buffering capacityagainst acidification (EC, UNECE and MFC,

1997).

Map 3.6.3 and Figure 3.6.7 show the sensitiv-ity to acidification of the European forestsoil, measured by the soil buffering capacityagainst added acids. The highest proportionof acid-sensitive sites are found in the Neth-erlands, Finland and Belgium. In Luxem-bourg, the Slovak Republic, Hungary,Slovenia, Portugal, Switzerland and Austriathe majority of the observed forest soils areresistant to acidification.

There have already been further substantialreductions in emissions of sulphur dioxide;nitrogen oxides and VOCs emissions will bereduced by 2010 by implementation ofpolicies in the pipeline (see Chapter 3.4).Nevertheless, there is still concern over acid

deposition in hot-spots and areas withsensitive ecosystems, and if acid depositiondoes not decrease, the area of Europeanforest under threat may increase by 50% to110 million ha (representing 45% of thetotal forest area) (EEA, 1995).

2.4.2 Heavy metalsSoils naturally contain trace elements, whichfunction as micro-nutrients essential to plantand animal growth, while high concentra-tions can be a threat to the food chain. Theelements of most concern are mercury (Hg),

lead (Pb), cadmium (Cd) and arsenic (As),which are especially toxic to humans andanimals, and copper (Cu), nickel (Ni) andcobalt (Co) which are of more concernbecause of phyto-toxicity. The toxicology ofthese contaminants depends on soil type,

vegetation and climate, as well as, theirconcentration.

Concentrations of heavy metals in soil covera very wide range. In many cases, the higher

values indicate contamination from mans

activities, although large values can occurbecause of natural geological or soil-formingconditions.

In forest soils, results from the above-men-tioned forest soil survey show that concentra-tions of heavy metals such as lead and zinc inhumus layers and topsoils follow regionalgradients, reflecting atmospheric depositionpatterns. The majority of sites with high leador zinc concentrations in the soil organiclayer are found in the region with the

highest deposition load. However, criticalconcentration of lead, zinc and cadmium areexceeded in less than 1% of sites for which

values have been reported. Exceedances ofcritical organic layer concentration ofchromium and copper have reported morefrequently, in 9% and 19% of the sitesrespectively.

Map 3.6.4 and Figure 3.6.8 show lead avail-ability in European forest soils. The risk oftoxic amounts of plant-available lead isassociated with highly industrialised areas in

Germany, England and Wales. All sitesclassified in the highest availability class arelocated in the region of Europe receiving ahigh or moderately high deposition load(EC,UN/ECE and MFC, 1997).

Heavy-metal exposure has been reducedthroughout Europe, and a further decline isexpected in the Accession Countries, al-though increases in cadmium and mercuryin waste are projected in the EEA countries(see Chapter 3.3).

Positive effects from these reductions onEuropean soils are expected, althoughmethodological differences between coun-tries preclude accurate quantitative assess-ment. Moreover, there are still major gaps inquantifying heavy-metal emission factorsfrom industrial processes and in knowledgeabout the toxic effects of heavy metal onecosystems or the bearing capacity of differ-ent soils.

2.4.3 Nutrient load

The over-application to soil of fertiliserswith a high phosphorus and nitrogencontent or livestock manure, together withacid depositions with a high content inthese two elements, can have important

effects on the environment. Here, capabilityof soil to provide nutrients to plant growthis affected, and its buffering and filteringcapacity plays an important role. Bothnitrogen and phosphorous are essentialelements for plant growth, but can becomedamaging when present in quantitiesexcessive to plant requirements. Theaccumulation may lead to the soil becomingsaturated and the excess may be leachedfrom the soil, eroded or simply washed offinto the groundwater, waterways and coastalsystems, causing eutrophication (see Chap-ter 3.5).

A high nitrogen content in soil may also bean important cause for the loss of vitality ofEuropean forests. In forest soils, a highernitrogen content in the organic layer hasbeen observed in areas receiving a highatmospheric deposition load compared

with remote areas of Europe. About 17%of the sites present high nitrogen levels inthe organic layer. A low nitrogen availabil-ity has been found in Scandinavian coun-tries and in the UK, while in the rest ofEurope very low availability is expected tooccur rarely. A concentration of sites with

high or very high nitrogen availability hasbeen observed in Germany, the SlovakRepublic and northern Spain (EC, UN/ECE and MFC, 1997).

Although fertiliser consumption was

constant or slightly decreased during thelast decade, nutrient loads (nitrogen andphosphate) from diffuse agriculturalsources remain high, with special refer-ence to parts of north-western Europe

where there is intensive livestock produc-tion (Map 3.6.5). However, phosphorus

are primarily aimed at combating pollutionin other compartments and affect soilsindirectly.

With special regard to local soil contamina-

tion, it can be said that most EU and Acces-sion Countries have recognised the need toset up regulatory frameworks on how tomanage existing local soil contaminationand how to prevent future contamination.National policies of most countries addressliability questions and the prevention ofnew pollution. With respect to existingcontamination, most western Europeancountries and some eastern Europeancountries also address the keeping ofregional inventories, financing aspects, and

site investigation procedures. A variety ofcountries have made an attempt to calculatetotal national clean-up costs. Though resultsof such calculations are not comparable,they are important indicators for theattention paid to this particular matter. Costestimates deriving from Accession Coun-tries usually address the environmentaldamage of former Soviet military bases. Inthe case of the Czech Republic and Hun-gary, national costs estimated go beyondthis issue.

The development of a policy frameworkwhich recognises the role of soil, takesaccount of the problems arising from thecompetition among its concurrent uses(ecological and socio-economical), and

aimed at the maintenance of its multiplefunctions, could have multiple benefits andcould achieve a consistent improvement ofEuropes environment as a whole. Such apolicy framework is currently absent at theEU level and in most EU Member States and

Accession Countries.

3.2. Monitoring and assessment frameworks for

soil what exists and what is neededThere is no European-wide monitoringnetwork for soil, although some progress hasmade in some areas, such as the monitoringof forest soils within the framework ofUNECE-ICP Forest and the EU Scheme forProtection of Forests already mentioned.

Statutory soil monitoring is carried out in a

number of Member States, but rarely for thepurposes of soil protection per se. Monitor-ing is more often performed in support of,for example, the provision of better plantnutrient advice for the agricultural sector.Further difficulties within the concept of soilmonitoring arise from the great diversity

which exists in the design of soil monitoringschemes, the frequency of sampling, therange of parameters determined, and themethods of analysis used. There are alsoincreasing problems of data ownership andtransfer (see Chapter 4.2). As a result of this

diversity, there is lack of harmonisation ofthe data derived from soil monitoring, andthere is no pan-European quality control ofthe existing soil-monitoring networks.

As shown by the multi-function/multi-impactapproach, soil monitoring and assessmentneed to be addressed in an integrated way.There is a need to work towards the estab-lishment of certain standards for all relevanttypes of soil degradation, based on a uniformgeneral methodology. An appropriate

degree of co-ordination at the EU levelwould be necessary to obtain some level ofuniformity between countries in the develop-ment of criteria and methodology for theproduction of relevant data on soil condi-tions.

To this end, a complete framework formonitoring, assessment and reporting onsoil issues in Europe must be developed,similar to those already in place for air and

water. This must include the harmonisation/streamlining of data collection/data flowactivities (setting up a European Soil Moni-toring Network and related databases), thedevelopment of policy-relevant indicators,and the establishment of a coherent report-ing mechanism on soil.
