AGRICULTURE
Land Fund Law (No. 18/1991) – a
fundamental change of property
over the land
-The transition from state and
collective property to private
ownership
-The land was divided among a
large number of owners (4.7
millions), each acquiring under 2
hectares
1990
-the allocated piece of land is often
fragmented into several parcels,
over 47 million parcels emerged
after the implementation of the Law

•A tendency of precipitation concentration
over short time intervals and an increase
of their torrential character
• rapid snowmelting
•flush flood events in small catchments

CASE STUDIES
BAIA MARE - TECHNOLOGICAL ACCIDENT AND
TRANSBOUNDARY POLLUTION
JANUARY AND MARCH 2000
• Two tailings dam failures in Maramures county
resulted in the release of 200 000 m³ of contaminated
water and 40 000 tonnes of tailings into tributaries of the
Tisa River, a major tributary of the Danube.
• Following these accidents, Institute of Geography in
collaboration with the University of Wales, UK initiated
a research programme in northwest Romania to establish
metal levels in rivers affected by the present and historic
mining activities.
