Geography, climate and population
Lithuania, with a total area of 65 300 km², is one of the three Baltic states. It is bordered in the west by the Baltic Sea, in the north by Latvia, in the east and southeast by Belarus, in the southwest by Poland and by Kaliningrad, which is part of the Russian Federation. It declared its independence from the Soviet Union in March 1990. For administrative purposes, Lithuania is divided into 10 counties. The counties are divided into 60 municipalities. The capital city is Vilnius.
Lithuania is part of the east European plain. Within the country, lowland plains alternate with hilly uplands. From west to east, three lowland plains can be distinguished: the Pajuris, middle lowland and eastern lowland. Similarly, there are three uplands: the Zemaiciai (or Baltic), Aukstaiciai and eastern upland. The peak of the highest hill is at 293 m above sea level. Forests cover around 30 percent of the country (EC, 2012).
The agricultural area, which is the sum of arable land, permanent crops and permanent meadows and pasture, is estimated at 2.89 million ha, which is 44 percent of the total area of the country. In 2013, the total physical cultivated area was estimated at 2.32 million ha, of which 99 percent (2.29 million ha) consisted of temporary crops and 1 percent (0.03 million ha) of permanent crops (Table 1). The central and western parts of Lithuania are the best regions for crop production, especially the middle lowland.
Lithuania is a semi-humid country. The climate is transitional between maritime and continental. In the 12-15 km-wide coastal zone it is maritime, and in the east of the country it is continental. The average annual precipitation is 656 mm, ranging from less than 550 mm in the north to a maximum of more than 846 mm in the Zemaiciai hills. Over two-thirds of the precipitation occurs during the warmer period, from April to October.
The average annual temperature is 6.5-7.9°C. The warmest month of the year is July with an average temperature of about 19.7°C and the coldest month is January with an average temperature of about minus 2.9°C.
In 2015, the total population was about 3 million, of which around 31 percent was rural (Table 1). Average population density in the country is 44 inhabitants/km². The average annual population growth rate in the 2005-2015 period has been estimated at minus 1.5 percent.
In 2014, the Human Development Index (HDI) ranks Lithuania 37 among 188 countries, while the Gender Inequality Index (GII) ranks it 23 among 155 countries, for which information was available. Life expectancy is 74 years and the under-five mortality is 5 per 1000 births, both progressing from 69 years and 20 per 1000 in the 1990s. With no significant distinction between boys and girls, around 95 percent of the children in 2013 are enrolled in primary education, and 96 percent for secondary education (WB, 2015). Adult literacy is 99.8 percent in 2012 (UNDP, 2015). In 2015, 97 percent of the total population had access to improved water sources (100 and 90 percent in urban and rural areas respectively) and 92 percent of the total population had access to improved sanitation (97 and 83 percent in urban and rural areas respectively) (JMP, 2015).
Economy, agriculture and food security
In 2014, the gross domestic product (GDP) was US$ 48 172 million and agriculture accounted for 3 percent of GDP, while in 1994 it accounted for 11 percent.
In the Soviet era, agriculture was collectivized and organized in large-scale farms. After independence, agriculture was restructured and the land returned to its former owners.
Lithuania gained membership in the World Trade Organization in 2001 and joined the European Union (EU) in 2004 and the Euro zone in 2015. Foreign investment and EU funding have aided in the transition from the former planned economy to a market economy. Lithuania was severely hit by the 2008-09 financial crisis, but the country has rebounded and become one of the fastest growing economies in the EU (CIA, 2015).
The main crops in Lithuania are winter and spring cereal accounting for 41 percent of the total, winter and spring rape seed accounting for 12 percent, perennial grassland accounting for 40 percent and other crops as pulses, potatoes, beetroots, fallow, etc. account for 7 percent.
Surface water and groundwater resources
Rivers and lakes have long been used as waterways, although, with the exception of the Nemunas river in the south of the country, they are not very suitable for navigation. Within the country, there are 722 rivers with a length of more than 10 km each and just 21 of them have a length of more than 100 km. Most of the rivers flow across the middle lowland and the western part of the Zemaiciai upland.
Lithuania is divided in four River Basin Districts (RBD):
The internal renewable surface water resources (IRSWR) are estimated at 15 360 million m³/year (Table 2). The incoming surface water resources are estimated at 9 040 million m³/year, of which 9 000 million m³ from Belarus and 40 million m³ from Poland. Total renewable surface water resources are thus estimated at 24 400 million m³/year. The outflow to the Russian Federation is estimated at 850 million m³/year, of which 840 million m³ through Nemunas and 10 million m³ through Pregolya. The outflow to Latvia is estimated at 4 010 million m³/year, of which 2 000 million m³ through Lielupe, 500 million m³ through Daugava, 1 300 million m³ through Venta and 210 million m³ through the western coast basin. This brings the total outflow to 4 860 million m³/year.
The largest groundwater reserves are in the eastern and southeastern parts of the country, as well as along the Neris and Nemunas valleys while the smallest reserves are in central Lithuania (MoE, 2014). Internal renewable groundwater resources are estimated at 1 100 million m³/year. It is considered that most of the flow is drained out by the river system and does not contribute to the total renewable water resources. The overlap between surface water and groundwater resources has been estimated at 1 000 million m³/year which brings the total renewable water resources to 24 500 million m³ (24 400+1 100-1 000) (Table 3).
In 2009, produced municipal wastewater was estimated at 262 million m³, treated municipal wastewater at 128 million m³ and direct use of treated wastewater at 5 million m³.
Lakes and dams
Lithuania has more than 2 800 lakes, of which 25 have surface areas of more than 10 km². They cover 1.5 percent of the total area of the country. Most lakes are concentrated in the Aukstaiciai uplands in the east of the country.
There are 20 large dams in Lithuania registered in ICOLD’s World Register of Large Dams (Burneikis, Punys and Zibiene, 2001). One large dam, the Kaunas dam, has been built on the Nemunas river for hydropower generation. Its total capacity is 462 million m³ and its useful capacity is 220 million m³. About 376 dams have been built for water storage for irrigation and flood control. Their total capacity is 1 360 million m³ and their useful capacity is 230 million m³. The reservoirs could also be useful for fishery and recreation. Total dam capacity is estimated at 1 822 million m³ and the useful capacity at 450 million m³.
International water issues
Lithuania takes part in the following agreements concerning the use of international watercourses, lakes or groundwater (UN, 2004):
All four RBDs in Lithuania are international. Nemunas RBD shares water courses with Belarus, Kaliningrad (Russian Federation) and Poland. The other three, Daugava, Venta and Lielupe RBDs, share water courses with Latvia (EC, 2015). However, no international river basin management plans (RBMPs) have yet been adopted.
Cooperation with Belarus and the Russian Federation in the field of protection of the environment, including water bodies, has been developed for a number of years on the basis of cooperation agreements signed by the Ministry of Environment of Lithuania, the Ministry of Natural Resources of Belarus and and the Ministry of Natural Resources of the Russian Federation. These agreements, however, don’t cover all relevant aspects regarding transboundary water resources. Some agreements with Belarus and the Russian Federation are:
The Nemunas RBD is shared with two EU Member States, Poland and Latvia, and two non-EU countries, Belarus and the Russian Federation (Kaliningrad oblast). The governments of Lithuania, the Russian Federation, Belarus, and the European Commission have initiated the preparation of an agreement on cooperation in the use and protection of water bodies within the Nemunas RBD. A draft agreement has been drawn up but has not been signed yet. No measures have been foreseen for Poland and Latvia, because the part of the Nemunas RBD in Poland constitutes only 287 km² (the upstream reaches of the rivers with no significant pressures), and the part of the RBD in Latvia constitutes only 100 km2 (the upstream reaches of the rivers with no significant pressures), and the results of water quality monitoring showed that the ecological status of the rivers along the Polish and Latvian border were good (EC, 2012).
Coordination of some RBMP elements with Latvia has occurred, but a joint RBMP has not been elaborated. An intergovernmental commission on transboundary cooperation between these two countries was set up following the “Agreement on Transfrontier Cooperation between the Government of Lithuania and the Government of Latvia” signed in 1999. Cooperation with Latvia seeking to create a joint River Basin District Management Plan will continue on the basis of this agreement and pursuant to the Technical Protocol of Cooperation in the Management of International River Basin Districts, signed between the Ministry of Environment of Lithuania and the Ministry of Environment of Latvia in 2003 (EC, 2012). The Lielupe and Venta rivers, shared between Lithuania and Latvia, are included in the list of European Main Transboundary Surface Waters. The water quality problems of these rivers can only be solved by means of international agreements, in compliance with the mechanisms provided in the Helsinki Convention on “Use and Protection of Transboundary Watercourses and International Lakes” adopted in 1992.
In 2003 and 2004, several seminars were held for Baltic experts to discuss identification of river basin districts, proposed typology and characteristics of surface water. Even if they have not led to a harmonized typology, experts had a regular information exchange with neighbouring colleagues. In 2003, permanent working groups were established.
Cooperation with Poland on issues of water protection is ensured through the commission of cooperation of Poland and Lithuania. It was established on the basis of the Agreement between the two countries on “Cooperation on the Issues of the Use of International Waters”. One of the objectives of the working groups of the commission is to cooperate in the development and implementation of the River Basin District Management Plan in international waters (EC, 2012).
In 2011, total water withdrawal was estimated at 631 million m3 of which 415.9 million m3 (66 percent) for industry, 149.9 million m3 (24 percent) for municipalities and 65.6 million m3 (10 percent) for agriculture including irrigation, livestock watering and cleaning, and aquaculture (Figure 1 and Table 4). Around 72 percent of total water withdrawal is withdrawn from surface water, 27 percent from groundwater and 1 percent by direct use of municipal treated wastewater (Figure 2).
In 1995, total water withdrawal was estimated at 4 352 million m³ and in 2005 it was estimated at 2 377 million³. The reason that these figure is so much higher than the water withdrawal in 2011 is that by far the largest part, (4 099 million m³ in 1995 and 2 098 million m³ in 2005) was needed for cooling of nuclear power plants. However, at the end of 2009 Lithuania, under pressure of the EU, closed down its last nuclear reactor, which had been generating 70 percent of its electricity. While electricity was a major export product, since closure of the nuclear plant more than 60 percent of Lithuania’s electricity is imported (WNA, 2016).
Irrigation and drainage
Evolution of irrigation development
The irrigation potential in the country has been estimated at 200 000 ha.
In the 1970s, in the Nemunas river delta about 40 000 ha of meadows in polders were protected by dams against flooding. About 100 pumping stations had been installed to remove excess water in periods of flood. However, since this led to moisture deficit in dry periods sluices were installed in the polders, enabling to regulate the water level in the ditches and to irrigate in the driest periods. In 1976, 2 200 such systems, called sluice systems, were exploited. However, these systems were not used for long as sprinkler irrigation soon proved to be a more effective system of irrigation under Lithuanian conditions.
Since 1965, a lot of research on sprinkler irrigation has been carried out. The first sprinkler irrigation systems were installed in 1965 in the Kaunas and Këdainiai districts in the centre, where for some time domestic wastewater was used for irrigation. However, after an outbreak of cholera in the region in about 1970, the use of domestic wastewater for irrigation was forbidden. In the period 1973-1985, 33 industrial pig complexes were built. Irrigation systems were installed on 6 600 ha close to these complexes, using the dung as fertilizer.
During the period 1970-1990, the construction of irrigation systems was rather expensive because of the need for reservoir construction. Nevertheless, irrigation systems increased rapidly. By the end of 1970, irrigation covered 5 100 ha. In 1975 and in 1990 it was 22 300 and 42 700 ha respectively.
During the Soviet period, large irrigation systems were installed (100-200 ha) on kolkhoz (collective farms) and sovkhoz (state farms). After they were broken up, private owners started working on small plots (8-20 ha) and many of the large irrigation systems stopped functioning. This is the reason for the rapid decrease in irrigation after the independence. While 42 700 ha were equipped for irrigation in 1990, only 9 247 ha were left equipped for irrigation in 1995. The rest of the system has largely been destroyed, as farmers have not been interested in using large, costly irrigation schemes.
At present, irrigation systems are not popular since equipment is expensive and, in many parts of the country rainfed cropping is very well possible. In 2012, the total area equipped for irrigation was estimated at 4 440 ha, which represents only 0.2 percent of total cultivated area (Table 5). In 2010 actually irrigated area accounted for 1 532 ha, which was only about one third of the area equipped for irrigation in that year.
In 2010, out of the total of 120 farms in the country that used irrigation, 56 farms used surface irrigation, 36 farms used sprinkler irrigation and 56 farms used localized irrigation. In that same year, 19 farms used on-farm groundwater, 66 farms used on-farm surface water (ponds or dams), 33 percent used off-farm surface water from lakes, rivers or watercourses, 10 farms used off-farm water from common water supply networks, and 10 farms used other sources of water. Out of those 120 farms, 72 farms were smaller than 2 ha, 15 farms had an area of 2-5 ha, 10 farms of 5-10 ha, 7 farms of 10-20 ha, 5 farms of 20-50 ha, 5 farms of 50-100 ha and 6 ha larger than 100 ha (Statistics Lithuania, 2012).
Role of irrigation in agricultural production, economy and society
In 2010, the actually irrigated area was 1 532 ha, of which 642 ha or 42 percent were potatoes, 614 ha or 40 percent vegetables and strawberries, 101 ha or 7 percent other temporary crops, 82 ha or 5 percent fruit trees and berry plants and 92 ha or 6 percent permanent meadows and pastures (Statistics Lithuania, 2012) (Table 5 and Figure 3).
Status and evolution of drainage systems
The main issue in relation to agriculture in Lithuania is the removal of excess water to enable cropping. In ancient times, Lithuanians removed excess moisture from fields by furrowing them, using a special way of ploughing, or by making ditches. The first subsurface drainage systems are said to have been installed in 1855. Drainage works increased significantly at the beginning of the twentieth century, starting with the beginning of cultivation in the Nemunas river delta. In 1918, about 5 900 ha were known to be drained. In 1939, 14 800 ha of land were intensively drained, including 11 800 ha by subsurface drainage. In addition, 457 700 ha of land were drained extensively. Around 1 million ha of wetland had been drained by 1970 and 2 million ha by 1978. In 1995, the total drained area was estimated at about 3 million ha, of which 2.6 million ha, or 86 percent, were equipped with subsurface drainage systems. The total length of subsurface drainage lines is almost 1.6 million km. It is calculated that drainage systems have been installed on 90 percent of the area needing drainage, which is estimated at almost 3.4 million ha, which is more than half of the total area of the country. In fact, the country remains one of the most extensively drained countries in the world (Povilaitisa et al, 2014).
Water management, policies and legislation related to water use in agriculture
The main institutions involved in water resources management are:
The river basin management plans (RBMP) for the Daugava, Lielupe, Nemunas, and Venta RBDs were adopted in 2010, implemented in the period from 2010 through 2015, and will be updated every six years, i.e. in 2015, 2021, etc. The plans present an overview of the RBD status and needs, provide information on water protection objectives, identify water bodies at risk of failing to achieve good status, foresee measures for achieving water protection objectives, etc. (EC, 2015; Länsstyrelsen Blekinge län, 2012).
There are pricing policies for water use in every sector in Lithuania. Costs for water supply and treatment are fully covered by user charges (UN, 2004).
External financial resources have come mainly from bilateral donors such as Sweden, Finland, Norway and Denmark, and also from the international institutions such as the Poland and Hungary: Assistance for Restructuring their Economies (PHARE) programme, the European Bank for Reconstruction and Development (EBRD), the Nordic Environment Finance Corporation (NEFCO) and the World Bank (UN, 2004).
Policies and legislation
The general legislation and regulatory framework for water management includes (UN, 2004):
The Law on Water regulates the ownership of the internal water bodies, the management, use and protection of water resources and the rights and obligations of users of internal bodies of water and their resources. According to the law, the use of water resources shall be regulated considering the needs of the economy and population. It should guarantee a sustainable use of surface and groundwater resources, prevent waters from pollution and protect the rights of owners of bodies of water and users of their water resources.
Environment and health
The most important sources of pollution of water are (Länsstyrelsen Blekinge län, 2012):
The quantitative and chemical condition of most of the groundwater basins is good; they are subject to surveillance monitoring. Five groundwater basins have been identified as being at risk, with parts having chloride and sulphate concentrations in excess of the drinking water standard due to natural causes. Monitoring of the problematic quality indicators was launched in these basins in 2013 (MoE, 2014).
The rivers of Lithuania will become particularly vulnerable in summer due to climate change. If the climate change scenarios come true, spring and autumn floods will change greatly. In summer, the water quality will suffer from low flows. The maximum summer temperature of lakes will rise and therefore the processes of eutrophication will accelerate (Climate Adaptation, 2015).
Drainage is usually carried out in conjunction with specific cultural practices: removing shrubs and stumps, gathering stones, ploughing drained swamps and fallow lands. However, sometimes too many shrubs are removed, resulting in an increase in soil erosion. For this reason, serious attention is being paid to environmental protection.
Prospects for agricultural water management
The protection of water and the sustainable management of inland water bodies is one of the main environmental challenges for the government of Lithuania. A programme of measures must be established for each river basin district in order to achieve water protection objectives.
