<strong>Soil</strong> Survey in Albania<br />

Introduction<br />

The history of soil survey investigations in Albania<br />

dates back to the late 1930s when the first book on<br />

the soils of the country was published (Zavalani,<br />

1938), but it was only after the Second World War<br />

that soil surveys really began. During the<br />

centralised economic and political system that<br />

lasted until the early 1990s, soil surveys were<br />

conducted regularly throughout the country.<br />

Initially, it was the <strong>Soil</strong> Science Department at the<br />

Agricultural University of Tirana that carried out<br />

these activities and then the <strong>Soil</strong> Science Institute<br />

(SSI) of Tirana, founded in 1971, took the lead.<br />

The latter is under the Ministry of Agriculture and<br />

Food (MAF) and is the only Institute in the country<br />

specialised in soil science.<br />

Until the early 1990s, the <strong>Soil</strong> Science Institute<br />

was very well organised, operating throughout the<br />

country, and conducting pedological surveys and<br />

fertility tests all over the agricultural land. Other<br />

activities included soil fertility and plant nutrition,<br />

drainage and irrigation research, soil microbiology<br />

studies, erosion control, and topographic surveys.<br />

There were 26 districts at this time in the country,<br />

each of them having its own soil laboratory and a<br />

small specialised staff, among them one general<br />

soil scientist and one soil chemist. The Institute<br />

provided scientific and technical guidelines for the<br />

‘district soil offices’, even though their<br />

management was handled by local administration.<br />

With the dawn of political changes and<br />

privatisation of the economy, commencing at the<br />

beginning of the last 1990s, the scientific<br />

institutions of the country went through drastic<br />

changes and setbacks. Compared with the year<br />

1990 the <strong>Soil</strong> Science Institute had experienced<br />

almost 70% reduction of its staff. The district soil<br />

offices were non-existent and few soil analyses<br />

were being made for the arable land. To overcome<br />

this situation an effort was made to rehabilitate the<br />

National <strong>Soil</strong> Laboratory at the SSI offices in<br />

Tirana.<br />

This was fully supported by a grant of the United<br />

States Agency for International Development<br />

(USAID) in 1998. At present this Laboratory is<br />

fully operational and can provide soil, water, plant<br />

and fertiliser analyses for major properties.<br />

<strong>Soil</strong> Mapping<br />

<strong>Soil</strong> Survey in Albania. Pandi Zdruli<br />

The first national soil map at scale 1:200,000 was<br />

compiled in 1958 (Veshi and Spaho, 1988). This<br />

was followed by intensive soil surveys, especially<br />

during the period 1971-1991, when detailed soil<br />

maps from 1:10,000 to 1:50,000 scale, along with<br />

soil reports, were prepared for each former<br />

agriculture co-operative, state farm and district. In<br />

addition to the arable land, soil surveys covered<br />

also natural pastures and forests, though the<br />

intensity of soil sampling was less detailed than the<br />

arable land. This indicates that soils have long<br />

been considered to be an important part of<br />

agricultural development.<br />

After the political change, soil survey and mapping<br />

was reduced drastically. Except for minimal<br />

surveys made by the <strong>Soil</strong> Science Institute, no<br />

other mapping was made until the mid 1990s when<br />

the USAID sponsored a national assessment of soil<br />

resources (Zdruli, 1997a). Another achievement<br />

was reported in 1998 when for the first time an<br />

Albanian soil data were introduced into the <strong>Soil</strong><br />

Geographic Database of Europe at scale<br />

1:1,000,000, sponsored by the <strong>European</strong> <strong>Soil</strong><br />

Bureau (ESB) at DG-JRC Ispra.<br />

This was followed in 2001 by a more detailed soil<br />

survey, under the <strong>IN</strong>TERREG II Programme<br />

sponsored by the <strong>European</strong> Commission and the<br />

Italian Government, aiming at the creation of a<br />

national soil database at 1:250,000 scale (Figure 1)<br />

and another much more detailed soil database for<br />

the coastal areas of the country at scale 1:50,000<br />

(Zdruli et al., 2003). The ESB was the technical<br />

coordinator of this project and the Mediterranean<br />

Agronomic Institute of Bari the implementing<br />

institution.<br />

This greatly advanced soil surveys in Albania and<br />

put the country at a high <strong>European</strong> standard, being<br />

the only one in Europe at that moment to have<br />

completed a national soil database according to the<br />

‘Georeferenced <strong>Soil</strong> Database for Europe’ Manual<br />

of Procedures-Version 1.1. (ESB, 1998, 2000)<br />

prepared by the Scientific Committee of the ESB.<br />

<strong>Soil</strong> Classification<br />

The national soil classification system and<br />

methods of soil resource inventory in Albania were<br />

developed locally with minimal inputs from the<br />

outside world. The system itself was a surrogate of<br />

the Russian system of soil classification. Due to<br />

the size of the country and particularly, to the<br />

40<br />

<strong>Soil</strong> Survey in Albania. Pandi Zdruli<br />

extent of arable land, the Albanian system served<br />

its purpose. It provided the first assessment of land<br />

resources and helped to make decisions on<br />

fertiliser use and land reclamation projects.<br />

However, modern soil science concepts were not<br />

used and the translation to other systems, such as<br />

the FAO Legend (FAO-UNESCO, 1974), World<br />

Reference Base for <strong>Soil</strong> Resources – WRB –<br />

(FAO, ISRIC and ISSS. 1998), and USDA <strong>Soil</strong><br />

Taxonomy (<strong>Soil</strong> Survey Staff, 1998) proved<br />

difficult.<br />

The first attempt to convert the national system of<br />

soil classification into other well-known systems<br />

was undertaken between 1994 and 1997. Zdruli


EUROPEAN <strong>SOIL</strong> BUREAU ⎯ RESEARCH REPORT NO. 9<br />

(1997a) provides the following soil orders of <strong>Soil</strong> Taxonomy for Albania (Table 1).<br />

The second major study (Zdruli et al., 2003)<br />

conducted in 2001 revealed the distribution of soils<br />

according to the WRB (Figure 2). The Albanian<br />

pedological landscape is very diverse and complex.<br />

The lower coastal area of the western part of the<br />

country was mainly formed during the Quaternary<br />

period by the fluvial activity of several rivers<br />

flowing to the Adriatic and Ionian Seas. The<br />

dominant soils are Cambisols, Luvisols, Fluvisols,<br />

and Phaeozems, associated with Vertisols,<br />

Solonchaks, Gleysols, Arenosols, Histosols and<br />

Calcisols.<br />

On the eastern side of the coastal flatlands extends<br />

the hilly area covered by Mediterranean shrubs,<br />

typically Macchia Mediterranea with cultivation of<br />

olive groves, vineyards, and fruit trees. <strong>Soil</strong>s are<br />

moderately deep, but highly eroded and<br />

mismanaged, particularly by overgrazing.<br />

Luvisols, Cambisols, and Calcisols are the most<br />

extensive. Mountains are spread throughout<br />

Albania from the Alps in the north to the central<br />

and southern areas. At lower altitudes, pine, beech,<br />

and oak forests predominate whereas the highest<br />

elevations are mainly just bare rock. Above<br />

2,000m a.s.l. alpine meadows occur.<br />

Land evaluation of agricultural<br />

potentials<br />

Based upon the soil data accumulated during the<br />

period 1970-1988, the <strong>Soil</strong> Science Institute in<br />

Tirana began in 1988 a Physical Land Evaluation<br />

Study for all the agricultural land of the country.<br />

The main soil characteristics used for this land<br />

evaluation exercise were soil depth, thickness of<br />

the humus horizon, organic matter content at 50cm<br />

depth, available phosphorus, texture, and available<br />

moisture content of the topsoil. <strong>Soil</strong> acidity,<br />

alkalinity, salinity and the presence of stones are<br />

main soil constraints in Albania. Relief is a<br />

determining factor for agriculture; therefore slope<br />

threshold values were an important part of the<br />

evaluation process. Finally, climate determined the<br />

ultimate value of the land. Socio-economic factors<br />

were not considered in this study.<br />

At the end of the study all the agricultural land was<br />

divided into ten classes. Land class 1 is the best for<br />

agriculture crops while class 10 is the worst.<br />

Integral parts of this study were the preparation of<br />

several land evaluation maps, which show the<br />

classes of land for each farm, district and the entire<br />

country. The western coastal field areas, occupying<br />

about 250,000ha, have been identified with the<br />

best land classes, which have good potential for<br />

intensive agriculture. Classes 1 to 4 occupy nearly<br />

75% of this area. Factors of soil formation,<br />

physical landscape and generally similar climatic<br />

conditions are the main factors influencing the<br />

high land values. Hilly areas occupy roughly<br />

220,000ha. These areas, along with the interior<br />

valleys, belong to a variety of land classes, though<br />

classes 4, 5 and 6 are dominant. The main reason<br />

for the decreasing land values in the hilly zone is<br />

slope. Mountain areas covering about 80,000ha<br />

include the lowest ranking land classes due to<br />

steep slopes and severe climatic conditions<br />

(Kaleshi et al., 1992).<br />

The most important soil constraints, such as<br />

salinity (about 10,000ha), textural class, soil depth,<br />

alkalinity (about 60,000ha) in the western coastal<br />

area, and acidity in about 70,000ha mostly in the<br />

north-eastern part of the country, were also<br />

identified. Possible interventions to mitigate the<br />

negative effects of these constraints may increase<br />

the land values by one or two classes.<br />

Land use assessment<br />

A first attempt to prepare maps for actual land use<br />

and potential land use planning was done by Zdruli<br />

(1997b). This was followed by two EU


EUROPEAN <strong>SOIL</strong> BUREAU ⎯ RESEARCH REPORT NO. 9<br />

sponsored projects in 1997 and one in 2003. The<br />

latter is still in progress and the results are still to<br />

be reported.<br />

Zdruli (1997b) reports the distribution of arable<br />

crops mainly in the coastal area and the interior<br />

valleys; fruit trees, olive groves and vineyards in<br />

the hills; and pastures along with forest at the<br />

higher elevations.<br />

Under the current conditions, because agricultural<br />

land in Albania is high fragmented, the<br />

implementation of large-scale projects on land<br />

management is almost impossible. One approach<br />

to the issue of land consolidation, and sustainable<br />

land use planning, is the development of land use<br />

policies for single or similar groups of crops to be<br />

cultivated in suitable agro-ecological regions.<br />

These methods, in a sense, will overcome the<br />

obstacle of small land holdings because it will be<br />

one or few crops to unify large areas and thousands<br />

of farmers. This depends though, on investments<br />

and particularly on local and regional markets.<br />

Fertiliser use<br />

The history of fertiliser use in Albania began in the<br />

early 1970's with the construction of two factories,<br />

one for nitrogen and another for phosphate<br />

fertilisers. The impact on agricultural production<br />

was immediate and was reflected in the doubling<br />

of the yields of major crops over a short period.<br />

The main fertilisers used were ammonium nitrate,<br />

urea, single super phosphate and potassium<br />

chloride and sulphate. Fertiliser use was rather<br />

stable during the period 1985-1990 but declined<br />

notably in 1991 to about 33% (Thompson and Xia,<br />

1992) of the average consumption during the<br />

previous six years. These declines resulted from<br />

the break-up of agricultural cooperatives and state<br />

farms, disruption of fertiliser distribution, lack of<br />

credit for fertiliser purchases, and relatively slow<br />

land reform.<br />

The US-based non-profit International Centre for<br />

<strong>Soil</strong> Fertility and Agricultural Development<br />

(IFDC) is assisting Albania in restructuring its<br />

fertiliser production and input markets through the<br />

support for local dealers that replaced the<br />

governmental controlled enterprises of agricultural<br />

inputs operating during the old regime. Since 1995<br />

fertiliser imports along with other inputs have<br />

increased greatly and continue to provide the<br />

greatest stimulus to the increase of agricultural<br />

production. It is important to emphasize that the<br />

efficiency of fertiliser use has improved<br />

significantly since the collapse of the centrally<br />

planned economic system. In addition, soil data<br />

play a crucial role when establishing the nutrient<br />

balance of soils, crop yields and the need for<br />

fertilisers.<br />

Natural resources<br />

conservation and<br />

management<br />

<strong>Soil</strong> Survey in Albania. Pandi Zdruli<br />

It is estimated that in Albania, in only one year,<br />

erosion washes away 1.2 million tons of organic<br />

carbon, 100,000 tons of nitrate salts, 60,000 tons of<br />

phosphates, and 16,000 tons of potassium salts<br />

(Laze and Kovaçi, 1996), while the total amount of<br />

fertilisers imported or produced by local industry is<br />

far less. Other studies (Qilimi, 1996) show that soil<br />

fertility is decreasing mainly because of reductions<br />

in organic matter content, nitrogen, and potassium<br />

compared to 20 years ago, resulting in nutrient<br />

mining of the soils.<br />

Zdruli and Lushaj (2000) report accelerated soil<br />

erosion, deforestation, overgrazing, soil pollution,<br />

re-salinisation, acidification, water logging,<br />

flooding, urbanisation and soil sealing, nutrient<br />

mining, and loss of soil fertility as perhaps the<br />

most alarming environmental problems in Albania.<br />

The basis for making these assessments remain the<br />

old and recent soil data supported by the use of a<br />

Geographic Information System (GIS) and<br />

fieldwork.<br />

While the legal status and institutional<br />

strengthening for the conservation of natural<br />

resources is making progress, the most<br />

constraining problem remains law implementation<br />

and enforcement. Deterioration of the forests and<br />

natural pastures is the most visible example of<br />

such effects. The agricultural land in Albania is a<br />

finite resource and there are no areas remaining<br />

where the cropland could expand. Many mistakes<br />

were made in the past by converting natural<br />

pastures and forests to cropland and the negative<br />

results of such actions are well known throughout<br />

the country. (Zdruli et al., 1997b; 1998).<br />

Future Perspectives<br />

The most striking process that happened in<br />

Albanian agriculture after the political upheaval<br />

was the change in land ownership. There were<br />

about 550 agricultural co-operatives and state<br />

farms until 1990 managing all the agricultural land<br />

(about 700,000ha) of the country. The picture in<br />

2001 shows the agricultural land being distributed<br />

among about 450,000 farm families averaging 1,3<br />

hectares per farm or 0,25ha per person distributed<br />

in 1.8 million parcels, often far from each other<br />

(Civici, 2001).<br />

This is the greatest ‘revolution’ in the modern<br />

times of Albania with respect to private land<br />

ownership. The process has gone on (and is still<br />

going on) with controversies on the way in which<br />

this privatisation was implemented.<br />

From the soils’ prospective, the change in land<br />

ownership has brought to difficult times in keeping<br />

the link between the thousands of newly created<br />

farmers and the corresponding governmental<br />

institutions. Even though many farmers recognise<br />

for instance, the importance of soil fertility and<br />

land conservation, few of them would consider<br />

paying for a soil survey investigation on their land.<br />

Consequently, the opinion of the governmental<br />

structures remains that public funds or<br />

international donors should sponsor soil survey<br />

programmes. This becomes a priority especially<br />

with the pace of increase in land degradation and<br />

environmental damage of Albania’s natural<br />

resources.<br />

In many areas, Albania is blessed with fertile soils,<br />

but the total amount of arable land is finite and<br />

may not be able to support the increase in<br />

population expected in the coming years. At<br />

present, the country relies heavily on agricultural<br />

imports, which could make it vulnerable to local or<br />

regional crises, putting food security at risk. To<br />
