Tarptautinës geologijos mokslø sàjungos (IUGS) Geological Survey of strateginiame veiklos plane teigiama, kad „Pasauliui Lithuania in 2003 reikia tolesniø geologiniø tyrimø, kad visuomenë bûtø turtingesnë, saugesnë ir sveikesnë. Taèiau The Strategic Action Plan for the International Union of visuomenë gali turëti naudos ið geomokslø rezultatø Geological Sciences (IUGS) states that the world needs further tik esant abipusiai geriems informaciniams ir geoscientific research to secure a more prosperous, safer and bendradarbiavimo ryðiams. Pagrindinis iððûkis healthier society. However, society can profit from the results geologams ir yra tai pasiekti“. of geosciences only when these are communicated well. To Lietuvos geologijos tarnyba, aktyvi minëtos achieve this is a major challenge to geoscientists. Tarptautinës geologijos mokslø sàjungos narë, Geological Survey of Lithuania, being an active member of IUGS, seeks to make shorter the information gap between kasmetine savo veiklos ataskaita bando bent ið dalies geoscientists and broader society by publishing this report of sumaþinti „informaciná atotrûká“ tarp geologinës annual activities. We believe that the results of our geological bendruomenës ir plaèios visuomenës. Ir daroma tai work will be implemented in various spheres of human ne savireklamos ar ávaizdþio formavimo tikslais, bet activities. tikikintis, kad LGT darbø rezultatai bus pritaikyti ir (Institute of Geosciences, Un. of Sao Paulo) that “geology is kitose srityse. Deja, reikia sutikti su Brazilijos San Paulo not, at present, part of the popular culture” (Episodes, geologijos mokslø instituto atstovu Umberto Cordani, Vol. 23, No. 3). kad „Geologija dar nëra tapusi populiarios kultûros The organizational structure of LGT has not been sritimi“. (Episodes, Vol. 23, No. 3). essentialy changed in 2003, except that the Department of Law and Personnel and Auditing Service were established. 2003 metais ðiek tiek pertvarkyta LGT struktûra: By the end of 2003 LGT had 115 employees, 78 having a ákurtas Teisës ir personalo skyrius, Vidaus audito university degree (11 doctors of physical sciences among them). tarnyba ir reorganizuota á savarankiðkà padaliná The budget of the last year was 4349.3 thousand Lt (versus laboratorija.

The LGT carried out four tojø, ið jø 42 valstybës tarnautojai ir 73 darbuotojai, programmes: State Regulation of the Underground Use, the dirbantys pagal darbo sutartis.

Nineteen legal acts were prepared to ensure a better regulation of the underground use in 2003.

Kitas seminaro no doubt that the ativities of LGT will contribute to the tikslas buvo aptarti ir paskatinti ekogeologiná international geoscientific cooperation and will be reflected bendradarbiavimà pasienio regionuose. Renginyje at the International Geological Congress in 2004 in Florence. dalyvavo 67 specialistai ið 20 ðaliø (visø pasaulio kontinentø). Geologiniø tyrimø duomenys buvo aktyviai teikiami praktiniam naudojimui. 2003 metais lankytojams iðduota 3 110 ataskaitø, 550 lapø ávairaus mastelio þemëlapiø, 230 geofiziniø tyrimø diagramø. Nors sumaþëjus finansinëms galimybëms 2003 metais iðleisti tik penki leidiniai, taèiau daugiau dëmesio skiriama namø puslapiui internete (www.lgt.lt), rengiami praneðimai þiniasklaidai, teikiama informacija pagal uþklausas ir kt. Tikimës, kad 2003 metais Lietuvos geologijos tarnyboje sukaupti nauji geologiniai duomenys padës ágyvendinti Lietuvos nacionalinës darnaus vystymosi strategijos prioritetus (Valstybës þinios. 2003, Nr. 89-4029). Manome, kad LGT darbai reikðmingai prisideda ne tik prie efektyvesnio gamtos iðtekliø naudojimo, bet ir prie tokiø prioritetiniø krypèiø – „nuosaikus ir darnus ûkio ðakø ir regionø ekonomikos vystymas“, „geresnë kraðtovaizdþio apsauga ir racionalus tvarkymas“ ar „pasaulio klimato kaitos ir jos padariniø ðvel- ninimas“. Neabejojame, kad mûsø veikla atsispindës ir tarptautinëje geologø bendruomenëje, juolab kad ðiais – 2004 metais Florencijoje vyks 32-asis pasaulio geologø kongresas.
