The Neman River and some of its tributaries are used for internal shipping (in 2000, 89 inland ships carried 900,000 tons of cargo, which is less than 1% of the total goods traffic).
Situated between 56.27 and 53.53 latitude and 20.56 and 26.50 longitude, Lithuania is glacially flat, except for morainic hills in the western uplands and eastern highlands no higher than 300 metres. The terrain is marked by numerous small lakes and swamps, and a mixed forest zone covers almost 33% of the country. The growing season lasts 169 days in the east and 202 days in the west, with most farmland consisting of sandy- or clay-loam soils. Limestone, clay, sand, and gravel are Lithuania's primary natural resources, but the coastal shelf offers perhaps 1,600,000 m3 (10 Mbbl) of oil deposits, and the southeast could provide high yields of iron ore and granite.
Lithuania has an abundance of limestone, clay, quartz sand, gypsum sand, and dolomite, which are suitable for making high-quality cement, glass, and ceramics. There also is an ample supply of mineral water, but energy sources and industrial materials are all in short supply. Oil was discovered in Lithuania in the 1950s, but only a few wells operate, and all that do are located in the western part of the country. It is estimated that the Baltic Sea shelf and the western region of Lithuania hold commercially viable amounts of oil, but if exploited this oil would satisfy only about 20 percent of Lithuania's annual need for petroleum products for the next twenty years. Lithuania has a large amount of thermal energy along the Baltic Sea coast which could be used to heat hundreds of thousands of homes, as is done in Iceland. In addition, iron ore deposits have been found in the southern region of Lithuania. But commercial exploitation of these deposits probably would require strip mining, which is environmentally unsound. Moreover, exploitation of these resources will depend on Lithuania's ability to attract capital and technology from abroad.
