1996 ARAL SEA GEOINFORMATION SYSTEM presentation program 1996 Includes chosen topics from GIS Compiled by Andrei Ptichnikov, Institute of Geography RAS and Sveta Kniazeva, All- Russian Forest Monitoring Center. Compiled by Andrei Ptichnikov, Institute of Geography RAS and Sveta Kniazeva, All- Russian Forest Monitoring Center.
Aral sea GIS features 3 main themes, including : - Physical geography and topography; - Socio-economic development and resources use; - Environmental problems and ways of their solution. n 49 thematic layers in English and Russian n Republican, regional and local levels of presentation n Detailed studies of AmuDarya and SyrDarya deltas n Remote Sensing layers from Landsat TM and MSS, Resource MSU- SK, MSU-E satellite platforms for 1973-1996 n Compatibility with GRID/GEMS specifications n Compiled using PC ARC-INFO and IDRISI software in UTM projection n Scales from 1:4 000 000 to 1:25 000. n Visualization of maps - using ArcView 2 software

ECOLOGICAL ISSUES Center of salt and dust transfer Fall of salt and dust > 20 tons/sq.km Fall of salt and dust > 200 tons/sq.km Fall of salt and dust > 600 tons/sq.km Fall of salt and dust > 80 tons/sq.km Lakes Rivers Administrative boundaries Environment pollution Environment pollution Aral sea Amount of salt-dust deposits from dry bottom of the Aral sea dry bottom of the Aral sea
ECOLOGICAL ISSUES ECOLOGICAL ISSUES Rehabilitation measures Desertic hemihalophyte Desertified halophyte shrubs Desiccated tugay complexes Desiccating and salinizing tugay complex Halophyte shrubs Halophyte shrubs and reeds Takyr without vegetation Xerohalophyte shrubs Salinized tugay shrub complexes Semidesertic hemihalophyte No data Landriv Forecasted ecosystems in the AmuDarya delta in 2000 - 2005 years
Medical anomalies, cases per 10000 Background (<0.5) Very low (0.5-06) Low (06-12) Moderate (12-18) High (18-24) Very high (24-30>) Dynamics of maligant diseases in Karakalpakia ( % ) 4,5 5,8 7,1 7,2 7,1 7,4 8,7 9,5 7,5 9,9 7,8 02 4 6810 1980 1981 1982 1983 1984 1985 1986 1987 1988 1989 1990 Kungrad Turtkul Nukus Chimbay Kegeil y Karauziak Bozatau Chumanay Berouny Ellikala Aral sea Kanlikuly Muinak Tachtakupyr Kungradsky Bayganinsky Chelkarsky Irgizsky Aralsky Kazalinsky Tamdynsky Suzaksky Kzylkumsky Peshkunsky Aral sea Socio-Economic development + + Public health
